DETAILED DESCRIPTION OF THE DISCLOSURE

[0020] The foregoing summary, as well as the following detailed description of certain embodiments will be better understood when read in conjunction with the appended drawings. As used herein, an element or step recited in the singular and preceded by the word a or an should be understood as not necessarily excluding the plural of the elements or steps. Further, references to one embodiment are not intended to be interpreted as excluding the existence of additional embodiments that also incorporate the recited features. Moreover, unless explicitly stated to the contrary, embodiments comprising or having an element or a plurality of elements having a particular condition can include additional elements not having that condition.

[0021] FIG. 1 illustrates a block diagram of a system 100 for removing a cap seal 102 from a fastener 104, according to an example of the present disclosure. The various blocks in the diagram of FIG. 1 are arranged to facilitate the following explanation, rather than to require or imply any particular configuration of the physical objects that are represented by the blocks. The fastener 104 is used to secure components 106 together. The components 106 can be panels, frame, beams, blocks, walls, and/or the like. The fastener 104 can be a screw, bolt, or the like having a shaft, which can be threaded, a head, and/or a nut. The cap seal 102 is initially secured to a portion of the fastener 104, such as the head or the nut. In at least one example, the cap seal 102 is formed from a polysulfide sealant, and is cured onto the fastener 104.

[0022] The system 100 includes a seal remover 108 coupled to a distal end 110 of an operative portion 112 of a tool 114. The tool 114 can be a drill, a right angle nut runner, or the like. The operative portion 112 can be a drill bit, a shaft, or the like that is configured to rotate about a central longitudinal axis. The operative portion 112 includes a proximal end 116 opposite from the distal end 110. The proximal end 116 can be operatively coupled to an actuator 118, such as a motor, that is configured to automatically rotate the operative portion. Alternatively, the tool 114 may not include the actuator 118. Instead, the operative portion 112 can be configured to be manually rotated.

[0023] In at least one example, the seal remover 108 is removably coupled to the distal end 110. For example, the seal remover 108 is an attachment that removably secures to the distal end 110, such as via one or more fasteners, snaps, latches, and/or the like. In this manner, the seal remover 108 can be selectively secured to and removed from the distal end 110. As another example, the seal remover 108 can be integrally formed with the operative portion 112. In particular, the seal remover 108 can form the distal end 110 of the operative portion 112.

[0024] The seal remover 108 includes a base 120, fingers 122 extending outwardly from the base 120 (that is, extending away from the distal end 110 of the operative portion 112 of the tool 114), and passages 124 between the fingers 122. For example, the fingers 122 can extend radially outward from a distal surface (away from the tool 114) of the base 120. The fingers 122 are configured to remove the cap seal 102 from the fastener 104, such as by abrading, grinding, frictionally rubbing, scrubbing, and/or cutting the cap seal 102 away from the fastener 104. The passages 124 allow for removed material from and/or portions of the cap seal 102 to discharge from the seal remover 108 during operation.

[0025] In operation, the tool 114 is moved into proximity of the cap seal 102, so that the fingers 122 engage (for example, are urged into and contact) one or more portions of the cap seal 102, for example, the exterior surface thereof. As the fingers 122 contact the cap seal 102, the tool 114 is operated to rotate the operation portion 112, and therefore the seal remover 108. For example, the actuator 118 can be activated to rotate the operative portion 112. As the operative portion 112 rotates, the fingers 122 of the seal remover 108 rotate about a central longitudinal axis of the operative portion 112. The rotation of the fingers 122 on and around the cap seal 102 acts to remove the cap seal 102 from the fastener 104, such as by abrading, grinding, scrubbing, frictionally rubbing, and/or cutting portions of the cap seal 102 away from the fastener 104. As portions of the cap seal 102 are removed from the fastener 104, the removed portions are centripetally accelerated away from the fastener 104, and are discharged out and through the passages 124 as the seal remover 108 continues to rotate. The tool 114 continues to be operated to rotate the seal remover 108 (and may be continually urged toward the cap seal 102) until the cap seal 102 is removed from the fastener 104.

[0026] As described herein, the system 100 for removing the cap seal 102 from the fastener 104 includes the seal remover 108 including the fingers 122 outwardly extending from the base 120. Passages 124 are defined between the fingers 122. The seal remover 108 is configured to be coupled to the distal end 110 of the operative portion 112 of the tool 114. The tool 114 is configured to be operated to rotate the seal remover 108 in relation to the cap seal 102 so that the fingers 122 remove the cap seal 102 from the fastener 104. Removed portions of the cap seal 102 are discharged through and out of the passages 124.

[0027] FIG. 2 illustrates a perspective top view of the system 100 being operated to remove a cap seal 102, according to an example of the present disclosure. As shown, the tool 114 can be a hand held tool, such as a nut runner, having an operative portion 112, such as rotatable shaft. The seal remover 108 includes the base 120, which can be secured to an adapter 130, such as a chuck, that is coupled to, or forms part of, the operative portion 112. Optionally, the adapter 130 can be part of the seal remover 108. The base 120 and the fingers 122 can be formed of a resilient material, such as a polymer, rubber, or the like. As examples, the seal remover 108 can be formed of nylon, rubber, polyetherimide, a polyacetal, and/or the like. If flexibility is desired, the seal remover 108 can be formed of a material, such as nylon or rubber. If a more rigid material is desired, the seal remover 108 can be formed of polyetherimide, polyacetal, or the like.

[0028] As shown, in order to remove the cap seal 102, the seal remover 108 is disposed onto and over the cap seal 102, such that the fingers 122 are disposed over and around an exposed end of the cap seal 102. The tool 114 is then operated to rotate the seal remover 108. As the seal remover 108 is rotated, the fingers 122 engage the material of the cap seal 102. In at least one example, as the seal remover 108 is urged onto the cap seal 102, the fingers 122 can outwardly flex and deflect over engaged portions of the cap seal 102, thereby providing increased friction therebetween. As the tool 114 is operated to rotate the seal remover 108, the fingers 122 rotate and around the engaged portions of the cap seal 102, thereby removing portions of the cap seal 102, such as by abrading, griding, scrubbing, frictionally rubbing, and/or cutting away portions of the cap seal 102.

[0029] FIG. 3 illustrates a perspective side view of the system 100 of FIG. 2 being operated to remove the cap seal. Referring to FIGS. 2 and 3, as the tool 114 is operated to urge the seal remover 108 further into the cap seal 102 in the direction of arrow A, and the seal remover 108 continues to rotate about a central longitudinal axis 132 of the operative portion 112 in the direction of arc B (such as a counterclockwise direction), the fingers 122 frictionally engage the cap seal 102, and remove portions thereof, which are discharged out of the passages 124 via centripetal acceleration. Optionally, the seal remover 108 can be rotated in a direction that is opposite of arc B (such as in a clockwise direction). The removed portions of the cap seal 102 can be discharged as sealant residue 133.

[0030] FIG. 4 illustrates a perspective view of a seal remover 108, according to an example of the present disclosure. Referring to FIGS. 1-4, the seal remover 108 includes the base 120, such as a circumferential main body. The base 120 can include one or more channels 134 configured to receive one or more pins, clips, screws, and/or the like that are configured to secure the seal remover 108 to the distal end 110 of the operative portion 112, such as via the adapter 130.

[0031] The fingers 122 outwardly extend from the base 120. Each finger 122 includes an extension beam 140 that is generally parallel with a central longitudinal axis 142 of the seal remover 108. The extension beam 140 extends from the base 120. When the seal remover 108 is connected to the distal end 110 of the operative portion 112, the central longitudinal axis 142 is coaxial with the central longitudinal axis 132 (shown in FIG. 3). A tooth 144 extends from an end of each extension beam 140 opposite from the base 120. Each tooth 144 includes slanted edges 146 that converge at a sharp apex 148. Thus, the fingers 122 includes teeth 144 that are configured to dig, cut, and/or the like into the cap seal 102 in order to remove the cap seal 102 as the seal remover 108 rotates.

[0032] In at least one example, the fingers 122 can be serrated, such as on or proximate edges. For example, each tooth 144 can include flat or slanted edges with a serrated end, which effectively grinds a polysulfide sealant material.

[0033] As shown, the seal remover 108 can include eight regularly-spaced circumferential fingers 122 disposed around a central receiving chamber 150. The receiving chamber 150 is sized and shaped to allow reception of the cap seal 102. As noted, the fingers 122 can be configured to outwardly deflect as the fingers 122 contact the cap seal 102. The flexible fingers 122 exert frictional force into the cap seal 102, which increases the rate of removal of material from the cap seal 102. As the seal remover 108 is rotated on and around the cap seal 102, the teeth 144 dig into the cap seal 102, and inner surfaces 152 of the extension beams 140 frictionally engage the cap seal 102, thereby causing portions of the cap seal 102 to break away, and discharge through the passages 124 as the sealant residue 133.

[0034] During a removal process, the fingers 122 follow a contour of the cap seal 102 and underlying portion of the fastener 104 (such as a nut) by deflection and flexion, thereby allowing for quick removal of the cap seal 102 from the fastener 104. As the tool 114 is operated to rotate the seal remover 108, the fingers 122 flex scrape off the cap seal 102 in a fast and clean pass, which is quicker and more efficient than removing the cap seal 102 with a plastic scraper. The seal remover 108 can be formed from a polymer, as noted, instead of a metal, which ensures that the seal remover 108 does not damage the underlying fastener 104.

[0035] Optionally, the seal remover 108 can include more or fewer fingers 122 than shown. For example, the seal remover 108 can include three, four, five, six, seven, nine, or more fingers 122 instead of eight.

[0036] FIG. 4 shows an example of the seal remover 108. It is to be understood that the size, shape, and various features shown in FIG. 4 can be different than shown. For example, the spacing between the fingers 122 can be greater or less than shown. Additionally, the fingers 122 can be longer, shorter, wider, or thinner than shown. The spacing between the fingers 122 can be uniform, or can differ between different sets of fingers 122. The lengths and widths of the extension beams 140 can be greater or less than shown. The number and orientation of cutting edges on the extension beams 140 and/or teeth 144 can vary from what is shown in FIG. 4.

[0037] Additionally, the extension beams 140 can be more or less flexible. The degree to which the extension beams 140 deflect from vertical can vary, depending on a desired amount of flexibility (or rigidity). As such, an amount of force that each cutting surface exerts into the cap seal 102 can vary, as desired.

[0038] The seal remover 108 shown and described in FIG. 4 can be a general device that is useful with various different types of fastener shapes and sizes. The seal remover 108 can be adapted and customized for a particular application, such as with respect to certain sizes and shapes of fasteners. The fingers 122 (including the extension beams 140 and the teeth 144) can be customized for a specific type of fastener profile, such as by shaping engaging/cutting edges specifically to complement an outer shape of a specific fastener type. Additionally, the material from which the seal remover 108 is fabricated may also be modified, such as by machining the teeth to have a desired orientation and/or position.

[0039] FIG. 5 illustrates an isometric view of a seal remover 108, according to an example of the present disclosure. The seal remover 108 shown in FIG. 5 is an example of a customized device, which can be configured to remove a cap seal from a fastener having a particular shape. For example, the seal remover 108 shown in FIG. 5 can be customized and configured to remove a cap seal from an aerospace major structure fastener, such as can be formed of Inconel, and configured to join a wing to a body structure of an aircraft. Referring to FIGS. 1 and 5, the fingers 122 can be configured to cut around portions of the cap seal 102. The fingers 122 are disposed around a central receiving chamber 159 configured to receive the cap seal 102. Each finger 122 includes a wedge-shaped main body 160 outwardly extending from the base 120. The main body 160 includes an arcuate outer wall 162 connected to an arcuate inner wall 164 by sidewalls 166 that angle toward each other from the outer wall 162 to the inner wall 164. As such, the outer wall 162 is larger (that is, extends over a greater radial distance) than the inner wall 164. The fingers 122 also includes an exposed cutting end 170 that connects to and over the outer wall 162 and the inner wall 164. The cutting end 170 includes a flat leading surface 172 connected to a beveled trailing surface 174. The flat leading surface 172 can be in a plane that is parallel to a plane in which a flat bottom surface 176 of the base 120 resides. The beveled trailing surface 174 downwardly cants from the flat leading surface 172. A leading edge 178 of the leading surface 172 can be sharp and configured to cut into the cap seal 102, while the beveled trailing surface 172 allows residue from the cut material of the cap seal 102 to fall away and off the cutting end 170.

[0040] As shown, each finger 122 can also include a cutting groove 180 on an interior surface 182 at a junction of the inner wall 164 and the cutting end 170. The cutting groove 180 includes an upright wall 184 connected to an angled wall 186 that downwardly cants toward a central longitudinal axis 188. The upright wall 184 includes an expanded leading edge 194 that connects to a tapered portion 196 that terminates in a tapered trailing edge 196. It has been found that the shapes of the cutting grooves 180 and the cutting ends 170 efficiently cut into the cap seal 102 as the tool 114 is operated.

[0041] Each passage 124 is defined between a sidewall 166 of a finger 122, and a sidewall 166 of a neighboring finger 122 (that is, a finger closest to a finger 122. The passages 124 include an inboard inlet 200 and an outboard outlet 202. The inlet 200 is smaller than the outlet 202. The passages 124 are also wedge shaped, and the expanded size of the outlet 202 in relation to the inlet 200 allows for quick and efficient removal of removed portions of the cap seal 102 during operation of the tool 114.

[0042] The cutting edges of each fingers 122, such as including the cutting groove 180 and the cutting end 170, and the passages 124 are configured to tightly conform to a size and shape of a portion of a fastener 104 so that cutting action rotates around the fastener 104 and clears the sealant quickly and efficiently, such as in under fifteen seconds.

[0043] Optionally, the seal remover 108 can include more or fewer fingers 122 than shown. For example, the seal remover 108 can include three, five, six, seven, eight, or more fingers 122 instead of four.

[0044] Referring to FIGS. 1-5, in at least one example, the seal remover 108 can include at least one finger 122 that is shaped as shown and described in relation to FIG. 4, and at least one other finger 122 that is shaped as shown and described in relation to FIG. 5.

[0045] FIG. 6 illustrates an isometric view of seal removers 108a, 108b, 108c, and 108d, according to an example of the present disclosure. Referring to FIGS. 1, 5, and 6, the seal removers 108a-108d can be shaped the same as one another, but have different sizes. In this manner, a seal remover 108a-108d can be selectively secured to, removed from, and replaced in relation to the distal end 110 based on a size of the cap seal 102. Seal removers 108 as shown in FIG. 4 can also include different sizes.

[0046] Referring to FIGS. 1-6, the seal removers 108 can be integrally molded and formed as a single piece, such as a from a plastic or rubber. In at least one example, the seal removers 108 can be formed via additive manufacturing.

[0047] It has been found that the seal removers 108 as shown and described herein reduce a time of removal of a cap seal 102 from a portion of a fastener 104 by at least 75%, and upwards of 95%. Further, by coupling the seal remover 108 to the tool 114 (instead of using a separate scraper), there is little to no risk of injury from slipping off a cap seal. Additionally, removal time can be further reduced by using a seal remover 108 that is customized to a particular fastener size and/or shape.

[0048] The fingers 122, such as cutting surfaces thereof, can be resharpened. For example, a flat hand file can be used to sharpen the cutting surfaces.

[0049] FIG. 7 illustrates a perspective view of a seal remover 108, according to an example of the present disclosure. Cutting surfaces of the fingers 122 can include serrations 220. The serrations 220 can be on exposed edges 224, such as at terminal ends 252. For example, each tooth 144 can include flat or slanted edges with serrations 220, which effectively grind a polysulfide sealant material.

[0050] One or more of the fingers 144 can also include a groove 250, such as a transverse V-shaped groove at a terminal end 252. In at least one example, the finger(s) 144 can include the groove 250, but not the serrations 220. Any of the embodiments described herein can include serrations, such as the serrations 220, and/or grooves, such as the groove 250.

[0051] FIG. 8 illustrates a flow chart of a method, according to an example of the present disclosure. Referring to FIGS. 1 and 8, the method is for removing the cap seal 102 from the fastener 104. The method includes coupling, at 300, the seal remover 108 to the distal end 110 of the operative portion 112 of the tool 114. The seal remover 108 includes the fingers 122 outwardly extending from the base 120. The passages 124 are defined between the fingers 122. The method also includes operating, at 302, the tool 114 to rotate the seal remover 108 in relation to the cap seal 102, removing, a 304, the cap seal 102 by the operating 302, and discharging, at 306, removed portions of the cap seal 102 through and out of the passages 124.
