[0074] FIG. 17 shows a purely schematic sectional view through the assembly device in FIG. 16.

[0075] FIG. 1 shows a purely schematic perspective exploded view of an assembly device 1 according to the invention. The assembly device 1 according to the invention is particularly suitable for pressing in components 100 such as, for example, bearings 100 and/or for retracting components 200 such as, for example, shafts 200 and/or for sliding on and/or pulling off components such as, for example, radial shaft seals, coupling parts etc.

[0076] In this context, the assembly device 1 according to the invention comprises a base body 2 which, in the exemplary embodiment shown here, is formed in a substantially tubular manner. A receiving means 4 for a counterpart 3 is provided on this base body 2, wherein the receiving means 4 is provided in the exemplary embodiment shown here as a separate part which can be connected here to the base body 2 by means of a locking device 8.

[0077] In the exemplary embodiment shown here, the base body 2 is connected to a handling means 400 or is provided by a part of this handling means 400.

[0078] Here, the handling means 400 in the exemplary embodiment shown has a rechargeable battery 401, so that the assembly device 1 can be operated in a mobile manner even without a cable- and/or hose-based power supply.

[0079] An actuator means 7 is arranged within the base body 2, which in the exemplary embodiment shown here is also provided by the handling means 400. In the exemplary embodiment shown here, the actuator means comprises a pressure cylinder 9 and/or a hydraulic system 9. However, in other configurations, instead of the pressure cylinder and/or instead of the hydraulic system, a worm drive 10 and/or a threaded rod 11 and/or other means for generating a linear movement can additionally or alternatively be provided.

[0080] All necessary components for extending the pressure cylinder 9 within the base body 2, such as, for example, electric motor, hydraulic pump, control valves, etc. are arranged here in the handle 402 of the handling means 400, wherein the pressure cylinder 9 can be extended by means of an actuating element 403. In the exemplary embodiment shown here, the handle 402 thus provides the drive or the housing for the drive for the actuator means 7.

[0081] The assembly device 1 further comprises a tube means 5, which can be slid over the base body 2 at least in sections. A recess 12 is provided in the base body 2 via which recess the actuator means 7 can enter into operative connection with the tube means 5 slid onto the base body 2.

[0082] A recess 13 is provided in the tube means 5, which is provided such that it corresponds to the recess 12 in the base body 2. If the tube means 5 is slid over the base body 2, an operative connection can be established between the actuator means or pressure cylinder 9 and the tube means 5 by means of a coupling element 14, in the exemplary embodiment shown here by means of a bolt 22. If the actuator means 7 is actuated or if the pressure cylinder 9 is extended, the tube means 5 is pushed forward via the coupling element 14.

[0083] The tube means 5 comprises a contact section 6 with which, for example, a bearing 100 can be pressed in, or which is supported against the housing part 300 when retracting a shaft. Depending on the exemplary embodiment, a fitting 20 can be provided which is supported against the contact section 6. Different contours and cross-sections or diameters can be adapted via such a fitting 20.

[0084] The receiving means 4 serves to receive the counterpart 3, wherein the counterpart 3 acts in particular as a tie rod. The counterpart 3 and/or the receiving means 4 have a connecting means 19 which enables a quick and reliable connection between counterpart 3 and base body 2 via the receiving means 4. In the exemplary embodiment shown, the counterpart 3 can simply be hooked in the connecting means 19 into the receiving means using a correspondingly configured connecting means 19.

[0085] In the exemplary embodiment shown, the tube means 5 has different inner diameters. The diameter of the receiving means 4 in the exemplary embodiment shown here is larger than the diameter of the base body 2. In order that the tube means 5 can nevertheless be displaced both over the base body 2 and over the receiving means 4, the tube means 5 is first slid over the base body 2. Subsequently, the receiving means 4 is inserted into a corresponding opening in the base body 2. The locking means 8 can then be inserted via the opening 23 in the tube means 5 so that the receiving means 4 is securely connected to the base body 2. In addition, the tube means 5 is secured against accidental dropping.

[0086] In the exemplary embodiment shown here, the counterpart 3 comprises a plate 17 which is supported as a tie rod against the housing part 300 when a component is retracted. Furthermore, the counterpart 3 here comprises a centering projection 26 via which the counterpart 3 can be inserted into the opening 301 in a defined manner.

[0087] Furthermore, in the exemplary embodiment shown here, the centering projection 26 serves as a stop or depth stop 27. Via this stop 27 it is achieved that a component 100 or bearing can be assembled in a defined manner since the press-in depth is limited.

[0088] FIG. 1 also shows that the counterpart 3 has a centering aid 28 for the component 100. Thus, for example, when pressing in a bearing 100, the bearing 100 can first be attached or slid onto the centering aid 28 passed through the opening 301. The component 100 pre-positioned in this way can then be pressed in in a defined manner by means of the assembly device 1.

[0089] FIG. 2 purely schematically shows how a component 100, in this case a bearing 100, is pressed in. For this purpose, the bearing 100 is arranged in front of the one side of the opening 301, wherein the counterpart 3 in the exemplary embodiment shown here is inserted from the other side of the opening 301 in the housing part 300 through the opening 301 and through the bearing 100.

[0090] The counterpart 3 is then hooked into the receiving means 4, wherein a fitting 20 is provided here which adapts the contact section 6 to the size of the bearing 100. In order that the counterpart 3 can be inserted into the receiving means 4 despite the fitting 20, a corresponding recess 21 is provided in the fitting 20. To prevent the fitting 20 from falling off the tube means 5, a locking means 24 is also provided here, which is designed here as a spring-loaded pressure piece. Other types of locking means can also be used in a useful and suitable manner to receive the fitting 20 securely on the tube means 5.

[0091] If the actuator means 7 in the exemplary embodiment shown here is now actuated, the pressure cylinder 9 is extended forwards, thus in the direction of the receiving means 4, whereby the tube means 5 is pushed forwards by the coupling of the actuator means 7 via the coupling element 14. As a result, the tube means 5 and the base body 5 or the receiving means 4 are displaced relative to each other so that the distance between the contact section 6 and the receiving means 4 is changed.

[0092] In doing so, the tube means 5 in the exemplary embodiment shown here moves forward over the receiving means 4 so that the distance between the contact section 6 and the counterpart 3 or the plate 17 of the counterpart 3 is reduced. Hereby, a pressing force is exerted on the bearing 100 so that the bearing is pushed into the opening 101 of the housing part 300.

[0093] FIG. 3 shows a purely schematic top view of an assembly device 1 according to the invention. Here too, it can be seen that the counterpart 3 is received in the receiving means 4 by means of a connecting means 19. Furthermore, it can be seen that a recess 13 is provided in the tube means 5, which recess has a first engagement section 15 and a second engagement section 16. Thus, a kind of a bayonet adjustment mechanism is provided.

[0094] This serves to increase the stroke of the tube means 5 in the exemplary embodiment shown here in two steps if the available stroke of the actuator means 7 or the pressure cylinder 9 is not sufficient. For this purpose, the tube means 5 is first brought into contact with the coupling element 14 by means of the first engagement section 15. The actuator means 7 is then actuated so that the pressure cylinder 9 extends.

[0095] If the stroke of the pressure cylinder 9 is not sufficient, the pressure cylinder or the actuator means 7 can be moved back, whereby the coupling element 14 also moves back. In this case, the retraction in the exemplary embodiment shown here is effected by a spring reset.

[0096] Now, the tube means 5 can be rotated so that the second engagement section 16 comes into contact with the coupling element 14. Now, the actuator means 7 can be actuated again so that the double stroke is available due to the embodiment of the tube means 5 with an engagement section 15 and a second engagement section 16. Depending on the configuration, it is also possible to work with even more engagement sections so that a desired stroke or displacement of the tube means 5 can be achieved.

[0097] FIGS. 4 to 6 show in purely schematic sectional views the pressing of a bearing 100 into an opening 301 in a housing part 300. In FIG. 4, the bearing 100 is still positioned in front of the opening 301. In the two views according to FIGS. 5 and 6, the bearing 100 is already fully pressed into the opening 301 of the housing part 300.

[0098] In this case, the position of the tube means 5 relative to the receiving means 4 can be seen in particular via the position of the coupling element 14 and the contact section 6. As can be seen in FIGS. 5 and 6, compared to the initial situation of the assembly device 14, the tube means 5 is pushed forward beyond the receiving means 4. As a result, the distance between the contact section 6 and the plate 17 of the counterpart 3 serving as a tie rod changes. Hereby, the bearing is optimally pressed into the opening 301.

[0099] Since the movement of the tube means 5 is effected here by means of a handling device and in particular by means of a hydraulic system, a particularly simple and rapid pressing-in of a bearing or a component 100 is achieved. Complicated handling using threaded rods and nuts is not necessary. It is also not necessary to drive in the bearing, which is relatively difficult since it requires to work relatively carefully so as not to damage the bearing.

[0100] In FIG. 7, a further exemplary embodiment of an assembly device 1 according to the invention is shown purely schematically in a perspective exploded view. In contrast to the exemplary embodiment according to FIG. 1, the counterpart 3 in this case does not have a plate 17 or an abutment but rather an attachment means 18.

[0101] Such an exemplary embodiment of an assembly device 1 according to the invention with a counterpart 3 configured in this way can be used in particular for retracting components 100 such as shafts 200. However, with an assembly device 1 configured in this way, it is also possible that components can be slid over other components and/or slid over other components and simultaneously and/or subsequently pressed into an opening.

[0102] In FIG. 8, retracting a component 200 or a shaft 200 into an opening 301 of a housing part 300 is shown purely schematically. Here, the counterpart 3 is firmly connected to the shaft 200 by means of the attachment means 18.

[0103] The counterpart 3 is then connected to the receiving means 4 by means of the connecting means 19.

[0104] When the actuator means 7 is actuated, the tube means 5 in the exemplary embodiment shown here is also pushed forwards over the receiving means 4, wherein in such a configuration, the contact section 6 or the fitting 20 is supported against the housing part 300 and pulls the shaft 200 through the opening 301.

[0105] In the exemplary embodiment shown here, both the tube means 5 and the fitting 20 are adapted such that the shaft 200 can be retracted at least in sections into the fitting 20 and the tube means 5.

[0106] FIGS. 9 to 14 show purely schematically in three different views how a shaft 200 is retracted into the opening.

[0107] FIG. 9 shows a side view of an assembly device 1 according to the invention, wherein a shaft 200 is arranged in front of the opening 301, wherein the counterpart 3 connected to the shaft 200 is passed through the opening 301 and inserted into the receiving means 4.

[0108] FIG. 10 shows a purely schematic sectional view from above through the sectional plane A-A in FIG. 9. Here, the counterpart 3 connected to the shaft 200 can be seen, which is screwed into the shaft 200 by means of an attachment means 18.

[0109] The counterpart 3 is passed through the opening 301 and inserted into the receiving means 4 so that the counterpart 3 is firmly connected to the base body 2. When the actuator means 7 is actuated, the tube means 5 is pushed forward. Since the contact section 6 or the fitting 20 is supported against the housing part 300, the relative movement of the tube means 5 to the receiving means 4 or to the base body 2 causes the shaft 200 to be retracted into the opening 301, whereby the shaft or the counterpart 3 is retracted into the tube means 5.

[0110] This is illustrated in FIGS. 11 and 12, wherein in FIG. 12 a sectional view from above through the sectional plane B-B in FIG. 11 is shown. Here, it can be seen that the counterpart 3 has already been partially retracted through the opening 301 and plunges into the tube means 5 or through the fitting 20.

[0111] In FIGS. 13 and 14, it is shown purely schematically that the shaft is drawn completely through the opening 301. For this purpose, the tube means 5 in the exemplary embodiment shown here is repositioned by means of a type of bayonet adjustment mechanism so that the coupling element 14 is no longer in engagement with the first engagement section 15 but rather with the second engagement section 16.

[0112] For this purpose, the actuator means 7 was first moved back, wherein subsequently the tube means 5 is rotated and is manually displaced and rotated here so that the coupling element 14 comes into engagement with the second engagement section.

[0113] When the actuator means 7 is extended again, the tube means 5 is advanced further so that the shaft 200 is retracted further or completely through the opening 301, and it can be seen in FIG. 14 that the counterpart 3 is now arranged completely in the tube means 5 with the shaft 200 also being retracted into the tube means 5 and through the fitting 20.

[0114] FIG. 15 illustrates a purely schematic perspective view of an exemplary embodiment of a tube means. Here too, the bayonet adjustment mechanism can be seen, by means of which the first engagement section 15 or the second adjustment section 16 can be brought into operative connection with the actuator means 7.

[0115] In FIGS. 16 and 17, a further exemplary embodiment of an assembly device 1 according to the invention is shown purely schematically. However, in the exemplary embodiment shown, no fitting 20 is provided, rather, the contact section 6 of the tube means 5 serves directly as the force-transmitting section or pressing section.

[0116] A further difference from the previously shown configurations is that the recess 13 in the tube means 5 is not formed to be closed. Here, the first engagement section 15 is provided in the recess 13. If more stroke or further displacement of the tube means 5 is required, the actuator means 7 can be moved back, wherein then the tube means 5 can also be rotated here with the coupling element 14 then pressing against the tube means 5 outside the recess 13 so that the edge 25 of the tube means 5 provides the second engagement section 16.

[0117] Depending on the configuration of the assembly device 1 or the actuator means 7 and the tube means 5, it is also possible that the adjustment between a first and a second or a further engagement section 15, 16 is not necessary. In that case, the recess 13 in the tube means 5 can also be provided as a simple through-hole, for example.
