A sealing fin fixing apparatus can fix a sealing fin to a rotor in a shortened period of time to minimize variations of the pullout strength of the sealing fin. In the sealing fin fixing apparatus that fixes the sealing fin in a sealing groove defined in the outer circumference of the rotor of a rotary machine and includes a headstock for setting a rotor thereon, a Z-stage movable along a Z-axis, an X-stage movable along an X-axis, a tool rest supported on the X-stage, and a caulking tool mounted on the tool rest and including a shank and a pressing roller, while the pressing roller is being held against a caulking wire inserted, together with the sealing fin, in the sealing groove in the rotor that is set on the headstock, the headstock is actuated to rotate the rotor, thereby caulking the caulking wire to fix the sealing fin to the rotor.

The diaphragm boss is fixed such that the shaft part and the enlarged-diameter part are exposed upwardly. The diaphragm member is held with an air suction force by a robot arm apparatus having an air suction part such that the small-diameter concave part and the large-diameter concave part are exposed downwardly. By controlling the robot arm apparatus, the diaphragm member is brought into contact with the diaphragm boss while tilting an axis of the diaphragm member with respect to an axis of the diaphragm boss. By controlling the robot arm apparatus, the small-diameter concave part and/or the large-diameter concave part of the diaphragm member are pressed against the diaphragm boss while rotating the diaphragm member around the axis of he diaphragm boss, so that the enlarged-diameter part is fitted into the large-diameter concave part and the shaft part is fitted into the small-diameter concave part.

Embodiments of the present disclosure provide an apparatus and method for mounting an O-ring to a work piece. The apparatus comprises a guiding component comprising a frustum portion adapted to be arranged coaxially with a groove formed on an end surface of the work piece for receiving the O-ring, a large end face of the frustum portion arranged adjacent to the end surface; a plurality of through slots each extending a predetermined distance radially from an edge of the large end face; and a pressing component comprising a plurality of fingers each adapted to be fitted in and moved along the corresponding through slot to push the O-ring that is placed on the frustum portion into the groove, wherein a diameter of the large end face is larger than an inner diameter of the groove.

Tool for installing O-rings in an inner diameter of a structure includes a plurality of held in a spaced, fixed parallel relationship to one another. A plurality of guide surfaces are secured with and disposed between the plates. A selectively-actuable finger actuator is disposed to move a plurality of fingers generally radially between the plurality of plates. Each of the plates includes a slot, and a loading pin is configured to be received within the slots. When at least one O-ring is disposed about a plurality of guide surfaces proximal the periphery of the plates, and the loading pin is moved within the slots, the loading pin pulls a loop of the O-rings toward the plate axis. When the loading pin is removed, the finger actuator may be actuated to move the fingers in the generally radial direction to move the at least one O-ring radially outward from the plates.

Embodiments of the present disclosure provide an apparatus and method for mounting an O-ring to a work piece. The apparatus comprises a guiding component comprising a frustum portion arranged coaxially with a groove formed on an end surface of the work piece for receiving the O-ring, a large end face of the frustum portion arranged adjacent to the end surface; and an operation component adapted to drive the guiding component to rotate back and forth about a central axis of the guiding component, wherein a diameter of the large end face is substantially same as an inner diameter of the O-ring to allow the O-ring surrounding and eccentric to the frustum portion to slide into the groove with a rotation of the guiding component.

An insertion tool may be utilized for placement of a seal into a groove of a component. The insertion tool may comprise a base and a seal lifting portion. The seal lifting portion may comprise a surface configured to selectably engage with a seal to move the seal between a lifted position and an unlifted position within an associated groove of a component. The surface of the seal lifting portion may be configured to continuously move the seal between the lifted position and unlifted position. The seal may have a first height h.sub.1 and a second height h.sub.2, wherein h.sub.2 may be less than h.sub.1. The seal may be stretched to h.sub.2 in the lifted position and returned to h.sub.1 in the unlifted positioned in the associated groove of the component.

An installation tool for installing a seal includes a shaft and a seal-engaging component coupled with the shaft. During an installation of the seal, the seal-engaging component is adapted to couple with the seal. The seal-engaging component includes a first surface and a second surface. The seal-engaging component also includes a first annular ring extending from the first surface and adapted to engage with the seal for coupling the seal with the seal-engaging component. The seal-engaging component further includes a second annular ring extending from the first surface. The installation tool also includes a sliding hammer adapted to slide along a length of the shaft. During the installation of the seal, the sliding hammer is adapted to apply a force to the seal-engaging component for installing the seal at a seal installation location.

Automatic seal applicator apparatuses comprise a seal applicator module comprising a conical element and a pair of jaws or fingers that separates a seal, such as an O-ring, a D-ring, or other like seal, from a dispensing sleeve, and automatically applies the same to a part. Moreover, the apparatus comprises a quick-release module for quickly and easily removing one or both the dispensing sleeve and the conical element. In addition, the apparatus comprises a turntable allowing multiple parts to have seals applied thereto automatically. Finally, a system of a plurality of seal applicator apparatuses may be utilized for applying a plurality of seals to parts automatically.

A method of processing O-rings in an automated mass production system includes: (a) advancing an O-ring retainer toward a loading position in alignment with an output end of a feed device; (b) discharging a leading O-ring from the output end in electronic synchronization with advancement of the O-ring retainer to the loading position to initiate loading of the O-ring into the retainer prior to the retainer arriving at the loading position; (c) after loading the O-ring into the retainer, advancing the retainer away from the loading position toward an unloading position; and (d) moving an end effector in electronic synchronization with advancement of the retainer to the unloading position to synchronize arrival of the retainer at the unloading position with arrival of the end effector at a pick-up position in alignment with the O-ring at the unloading position for pick up of the O-ring by the end effector.

A plug for isolating a wellbore. The plug can include a body having a first end and a second end, wherein the body is formed from one or more composite materials and adapted to receive a setting tool through the first end thereof, at least one malleable element disposed about the body, at least one slip disposed about the body, at least one conical member disposed about the body, and one or more shearable threads disposed on an inner surface of the body, adjacent the second end thereof, wherein the one or more shearable threads are adapted to receive at least a portion of a setting tool that enters the body through the first end thereof, and wherein the one or more shearable threads are adapted to engage the setting tool when disposed through the body and adapted to release the setting tool when exposed to a predetermined axial force.
