ASSEMBLY DEVICE AND METHOD FOR ASSEMBLING COMPONENTS

Description

[0001] The present invention relates to an assembly device, in particular for pressing in components such as bearings and / or for pulling in components such as shafts into a designated opening in a housing part or the like, and / or for sliding components onto and / or off. The assembly device comprises at least one base body, at least one counterpart, and at least one tube assembly. The present invention also relates to two methods for operating such an assembly device.

[0002] In systems, machines, and vehicles with moving parts, bearings are often pressed into designated openings or driven in using specially shaped sleeves. Depending on the design, shafts are then driven into these bearings to provide moving parts for specific movements.

[0003] Pressing bearings into designated openings is typically done using special pressing dies. Alternatively, tools are often used, which usually include a threaded rod. This threaded rod is inserted through the opening in a support or other housing component into which the bearing is to be pressed. The bearing is then placed on the rod, and a press plate is slid onto each side. Nuts are then tightened, which continuously move the two press plates closer together until the bearing is pressed into the opening.

[0004] Pressing in bearings using such tools is generally reliable. However, assembling the tools is quite complex, and pressing in bearings takes a relatively long time. Hammering in bearings carries certain risks of damage and injury and is also time-consuming.

[0005] Once a bearing is pressed in, a shaft is then driven into the pressed-in bearing, depending on the type of machine, system, or vehicle and the application. This process is also time-consuming and strenuous, and it's relatively easy to damage the shaft, the bearing, and / or other components.

[0006] If the shaft also needs to be supported on the opposite side, the bearing cannot first be pressed in and then the shaft driven in, as the shaft is usually already inserted into the opening. Therefore, on the opposite side, the bearing must generally be hammered onto the shaft and simultaneously pressed or driven into the opening. This is also time-consuming and can easily lead to damage. A tool according to the preamble of claim 1 is shown in document US 5,402,560 A.

[0007] The object of the present invention is therefore to simplify, accelerate and preferably make more reliable the pressing in and / or pulling in of components.

[0008] This problem is solved by an assembly device with the features of claim 1, by a method for pressing in a component such as a bearing with the features of claim 10, and by a method for pulling in a component such as a shaft with the features of claim 12. Preferred embodiments of the invention are the subject of the dependent claims. Further advantages and features of the present invention will become apparent from the general description and the description of the exemplary embodiment.

[0009] The assembly device according to the invention is particularly suitable for the assembly and disassembly of components. Specifically, it is suitable for pressing in components such as bearings, shaft seals, coupling parts, etc., and / or for pulling components such as shafts into a designated opening in a housing part or the like, and / or for sliding components onto and / or off. The assembly device comprises at least one base body and at least one counterpart. The base body has at least one receiving device for receiving the at least one counterpart. Furthermore, the assembly device comprises at least one pipe assembly with at least one contact section, wherein the pipe assembly is slid over the base body at least partially. The pipe assembly and the base body, respectively,The pipe assembly and the receiving device can be moved relative to each other by means of at least one actuator device, so that the distance between the section of the pipe assembly and the receiving device can be changed.

[0010] Due to the components being movable relative to each other, or by changing the distance between the system section and the receiving device, the pipe assembly and the base body or the receiving device are moved relative to each other, so that the system section presses against the component to be mounted and thus transmits a force, or supports itself against the housing part, so that the component to be mounted is pulled.

[0011] As previously explained, the assembly device is used for mounting components. However, it is also possible to disassemble components mounted using the assembly device, such as bearings, or to remove components.

[0012] Preferably, the pipe assembly and the base body interact in a sliding fit manner. This allows the pipe assembly to be guided on the base body, at least partially, and to slide over it when the distance changes.

[0013] The actuator serves to change the distance between the section of the pipe system and the receiving device, whereby the actuator can, in particular, be part of a handling device, which is especially mobile. For example, a cordless screwdriver or a hydraulic device in the form of a hand tool can be used to provide a suitable actuator.

[0014] The counterpart provides, in particular, a type of tie rod, which is either attached to a component to be pulled in or used as a counter bearing for pressing in components.

[0015] The support section of the pipe assembly serves to support the pipe assembly against the housing part during insertion and to transmit force to a component such as a bearing during press-fitting. For this purpose, the diameter of the support section is adapted to the intended use, so that it can either plunge into the opening into which a bearing is to be pressed and / or be supported against the housing part outside the opening.

[0016] In all embodiments, it is preferred that all components of the assembly device according to the invention are coordinated and designed in such a way that the rules of proper assembly are observed.

[0017] The assembly device according to the invention offers many advantages. A significant advantage is that the assembly device according to the invention considerably facilitates and speeds up the assembly of components, such as pressing in bearings or pulling in shafts.

[0018] Furthermore, with the assembly device according to the invention, there is no longer a risk of damage to the components when inserting shafts or pressing in bearings, since the simple handling of the assembly device and the application of force by means of the actuator device enable targeted insertion of the components.

[0019] Furthermore, the installation of the mounting device, i.e., the insertion of the counterpart into the receiving device, is very simple, and the time-consuming assembly of tool parts is eliminated.

[0020] Another significant advantage of the assembly device according to the invention is that a user can perform the necessary work steps for pressing in, pulling in, or the like in a much more ergonomic manner. Furthermore, damage to components and / or injury to the user from impact tools is eliminated.

[0021] Furthermore, the noise emission when using the mounting device according to the invention is significantly lower, at least than when conventionally hammering in components.

[0022] According to the invention, the tube assembly can be displaced at least partially beyond the receiving device. This can be achieved by pushing the tube assembly towards the housing part into which a component is to be pressed or drawn. In preferred embodiments, the receiving device can also be retracted relative to the tube assembly to receive the counterpart. In both cases, however, it is preferred that the tube assembly is displaced relative to the receiving device, with the tube assembly projecting at least partially beyond the receiving device.

[0023] Preferably, the receiving device is detachably and / or interchangeably mounted on the base body. Depending on the design, however, the receiving device can also be manufactured integrally with the base body or be permanently connected to it. In the case of a detachable and / or interchangeable design of the receiving device, different receiving devices can be provided depending on the intended use. These are preferably connected to the base body in such a way that sufficient force absorption is possible.

[0024] In advantageous embodiments, the inner diameter of the pipe assembly is adapted, at least partially, to at least one outer diameter of the base body and / or the receiving device and / or the mating part. It is particularly preferred that the inner diameter of the pipe assembly is also adapted to the diameter of the component to be mounted, such as a shaft or a bearing. Thus, depending on the embodiment, the pipe assembly can be slid over the component, at least partially, if required.

[0025] Preferably, the counterpart comprises at least one cross-section serving as a centering projection and / or a stop. Such a centering projection allows the counterpart to be centered within the opening in a housing part, thus ensuring a defined insertion depth of components. The maximum insertion depth can be predetermined by such a stop or depth stop. When pressing in a bearing, the cross-section of the centering projection preferably corresponds to the cross-section of the opening and thus to the outer diameter of the component.

[0026] Preferably, the counterpart includes at least one section that serves as a centering aid for the component to be mounted. For example, when pressing in bearings, the counterpart can be guided through the opening in the housing part and the bearing can be slid onto the centering aid in front of the opening.

[0027] In advantageous embodiments, the receiving device is connected to the base body via at least one locking device. In particular, this locking can be achieved by means of a locking pin, which is inserted into corresponding openings in the base body and the receiving device. To ensure secure reception, the locking pin can be secured. For this purpose, a groove can preferably be provided in the locking pin, into which a spring-loaded locking pin preferably engages. In other embodiments, the connection by means of a locking device can also be achieved by using a bolt or the like.

[0028] Preferably, the base body is designed in a tubular form, at least in sections. A round or rounded contour is particularly preferred, wherein the contour of the tubular element is preferably adapted to the contour of the base body, at least in sections.

[0029] Particularly preferably, the base body is designed to be rotatable, at least in sections, or is rotatably mounted. Rotation about the longitudinal axis of the base body is especially preferred, so that the base body can be aligned in different orientations on the handling device, for example.

[0030] In suitable embodiments, the actuator assembly comprises at least one pressure cylinder and / or at least one worm drive and / or at least one threaded rod and / or other devices for generating a linear motion. Other suitable drives can also be advantageously used.

[0031] Preferably, the pressure cylinder and / or the worm drive and / or the threaded rod are arranged at least partially within the base body. This design allows for a concealed or covered drive, resulting in particularly reliable operation of the assembly device. Furthermore, a compact device can also be provided.

[0032] According to the invention, at least one opening is provided in the base body through which the actuator assembly enters into operative connection with the pipe assembly. In advantageous embodiments, the opening is essentially slot-shaped, so that a kind of sliding fit is formed.

[0033] According to the invention, the pipe assembly has at least one corresponding opening, at least in sections, through which the pipe assembly is connected to the actuator assembly via at least one coupling element. For example, the pipe assembly can be slid over the base body, with a coupling element providing the connection between the actuator assembly and the pipe assembly as soon as the openings in the base body and in the pipe assembly are sufficiently aligned. A coupling element can, for example, be provided by a bolt.

[0034] Preferably, the clearance in the pipe assembly is designed, at least in sections, essentially as a slot.

[0035] Particularly when the clearance in the pipe assembly is designed as a slot, it is preferred that the clearance includes at least one first engagement section and at least one second engagement section. This allows the adjustment range or stroke of the pipe assembly to be adapted and extended as needed. The at least two engagement sections can be designed as bayonet fittings, so that the respective engagement sections are set by moving the pipe assembly and performing a rotation and / or pivoting operation.

[0036] Preferably, the counterpart comprises at least one plate. Such a plate can, for example, provide a tie rod when pressing bearings into an opening in a housing part, which is supported by the bearing and / or the housing part. The plate can be supported, in particular, by the housing part, so that, for example, when the pipe assembly is extended, a tensile force is generated between the receiving device and the counterpart.

[0037] In advantageous embodiments, the counterpart includes at least one fastening device. In such an embodiment, the counterpart can be fixed to a component by means of a fastening device. For example, the counterpart can be fixed to a shaft to be pulled in by means of a bolt or the like, so that the counterpart also acts as a tie rod for the component to be pulled in.

[0038] Preferably, the counterpart and / or the receiving device comprises at least one connecting device. Such a connecting device serves in particular for quickly connecting the counterpart to the receiving device. This connection can be effected in particular by snapping, hooking, inserting, twisting, screwing in, or another rapid joining method, especially without the use of tools.

[0039] In advantageous embodiments, the counterpart includes at least one quick-release fastener. In such an embodiment, the counterpart can, in particular, comprise, for example, a threaded rod onto which a plate can be slid, or which comprises a rod. Furthermore, preferably at least one quick-release nut or the like is provided, so that particularly quick fixing and adjustment can be achieved.

[0040] Preferably, at least one fitting is provided, which allows for the adaptation of at least one cross-section and / or at least one contour, e.g., for different bearing and / or component diameters. Such a fitting can, for example, be designed in the form of a sleeve, which, according to the requirements, can have a certain outer cross-section and / or inner cross-section and / or a specific contour. Such a fitting preferably interacts with the mounting section of the pipe assembly or provides a new mounting section or press section. The fitting can thus be supported against the mounting section of the pipe assembly, preferably with a corresponding receptacle on the pipe assembly onto which, for example, the fitting can be slid. Preferably, the fitting is fixed to the pipe assembly so that it cannot fall off during use of the assembly device.Here too, a quick-release fastener or quick-connect fitting can be provided; for example, a spring-loaded pressure piece can be used, which ensures a secure but detachable connection of the fitting to the pipe assembly. Other locking mechanisms can also be used to advantage.

[0041] Preferably, the fitting has at least one clearance. This clearance serves in particular as access to the receiving device for the mating part. For example, the mating part can be inserted into the receiving device through the clearance. Subsequently, depending on the design, the fitting can also serve as a locking mechanism, for example, by being rotated so that access to the receiving device is no longer free, thus temporarily preventing the mating part inserted into the receiving device from being removed.

[0042] The method according to the invention is suitable for pressing a component, such as a bearing, into an opening of a housing part using an assembly device as previously described. The following steps are carried out in a suitable sequence. A bearing is positioned in front of one side of an opening in a housing part. The counterpart is then inserted from the other side of the opening through the opening and the bearing. Alternatively, the counterpart can also be inserted from the side of the bearing through the opening. The counterpart is connected to the base body via the receiving device. The distance between the mounting section and the receiving device is changed by means of the actuator device for pressing in the bearing. In particular, the distance can be achieved by extending the tube device, whereby the tube device presses against the bearing and pushes it into the opening. The counterpart serves as a counter bearing.

[0043] Preferably, the actuator assembly is then retracted and the pipe assembly is returned, for example manually, so that the connection between the counterpart and the receiving device can be released, allowing the mounting device to be removed from the housing part.

[0044] In other embodiments, however, the receiving device with the inserted counterpart can also be withdrawn relative to the pipe device, whereby in this embodiment too the pipe device is displaced beyond the receiving device or the base body in the direction of the housing part and thus presses in the bearing.

[0045] The inventive method for pressing in components also offers the advantages already described above.

[0046] Preferably, the following steps are carried out at a suitable location and in a suitable sequence. The actuator is retracted. The pipe assembly is rotated, and the second engagement section is inserted. This is followed by a further adjustment of the distance between the system section and the receiving device using the actuator. These process steps are particularly suitable when the stroke or travel range provided by the actuator and / or the handling device is insufficient to achieve a sufficient change in distance between the pipe assembly and the receiving device. This can be very useful, for example, to keep the actuator as small as possible, since it is preferably a hand-held device that could otherwise become too unwieldy.If insufficient stroke is achieved, the actuator can be retracted and the pipe assembly switched from the first engagement section to the second, allowing for further adjustment of the distance between the receiving section and the pipe assembly, depending on the design. In this way, the stroke can be increased, depending on the configuration. If multiple engagement sections are provided, this process can be repeated according to the number of engagement sections, depending on the configuration.

[0047] The actuator assembly can then be retracted, with the pipe assembly preferably being returned to the first engagement position or to the first engagement section.

[0048] The inventive method for drawing components such as a shaft into an opening of a housing part using an assembly device as previously described is characterized by the following steps in a suitable sequence. The counterpart is attached to the component or shaft. The shaft or component with the attached counterpart is passed through a corresponding opening in a housing part. Depending on the embodiment, initially only the counterpart is guided through the opening. The counterpart is connected to the base body via the receiving device, and the distance between the mounting section and the receiving device is changed by means of the actuator device to draw in the shaft or component.

[0049] Preferably, the cross-section of the counterpart is at least slightly smaller than the cross-section of the opening and / or the component, so that a sliding and / or sliding fit is created, which preferably serves as a centering and / or assembly aid.

[0050] This method according to the invention also offers the advantages that have already been explained for the assembly device.

[0051] The change in distance between the pipe assembly and the receiving section can be achieved in particular by extending the pipe assembly and / or retracting the receiving assembly.

[0052] After the process has been carried out, or after the shaft has been inserted, the actuator is preferably retracted and the tube is moved back manually or automatically so that the counterpart can be removed from the receiving device. Preferably, the counterpart is removed from the component or shaft after insertion.

[0053] Preferably, the method further optionally comprises the following steps at a suitable location and in a suitable sequence. The actuator assembly is retracted. The pipe assembly is rotated, and the second engagement section is adjusted. This is followed by a further adjustment of the distance between the system section and the receiving device using the actuator assembly. As previously described for pressing a component, such as a bearing, into an opening, these additional process steps serve to compensate for any insufficient stroke or adjustability by changing the engagement sections on the pipe assembly.

[0054] The methods described above can also be used analogously to remove or detach components, or, for example, to press a bearing into a corresponding opening in a housing part if a shaft already passes through this opening. For this purpose, the counterpart is attached to the shaft, which is already guided through the opening in the housing part. The bearing to be slid or pressed in is then guided, at least partially, over the counterpart, and the counterpart is connected to the receiving device or the base body. Subsequently, by changing the distance between the receiving device and the tube assembly, the bearing is pushed or pressed over the shaft and then into the opening, with the counterpart acting as a tie rod and absorbing the force applied to the shaft.

[0055] Further advantages and features of the present invention will become apparent from the exemplary embodiment, which is explained below with reference to the accompanying figures.

[0056] The figures show: Fig. 1 is a purely schematic representation of an embodiment of an assembly device according to the invention in an exploded view; Fig. 2 is a purely schematic representation of an embodiment of an assembly device according to the invention in a side view during the insertion of a bearing into a housing part; Fig. 3 is a purely schematic representation of an embodiment of an assembly device according to the invention in a top view; Fig. 4 is a purely schematic representation of an embodiment of an assembly device according to the invention during the insertion of a bearing into a housing part in a top sectional view; Fig. 5 is a purely schematic representation of an embodiment of an assembly device according to the invention during the insertion of a bearing into a housing part in a top sectional view; Fig. 6 is the view according to Figure 5with fully inserted bearing; Fig. 7 a purely schematic representation of a further embodiment of an assembly device according to the invention in an exploded view; Fig. 8 a purely schematic representation of an embodiment of an assembly device according to the invention during the insertion of a shaft into a housing part in a top view; Fig. 9 a purely schematic representation of an embodiment of an assembly device according to the invention at the beginning of the insertion of a shaft into a housing part in a side view; Fig. 10 a sectional view through the section plane AA in Figure 9 Fig. 11 is a purely schematic representation of an embodiment of an assembly device according to the invention during the insertion of a shaft into a housing part in a side view; Fig. 12 is a sectional view through the section plane BB.

Figure 16 .

[0057] In Figure 1A purely schematic assembly device 1 according to the invention is shown in a perspective exploded view. The assembly device 1 according to the invention is particularly suitable for pressing in components 100, such as bearings 100, and / or for pulling in components 200, such as shafts 200, and / or for sliding on and / or pulling off components, such as radial shaft seals, coupling parts, etc.

[0058] The assembly device 1 according to the invention comprises a base body 2, which in the embodiment shown here is essentially tubular. A receiving device 4 for a counterpart 3 is provided on this base body 2, wherein the receiving device 4 is provided as a separate part in the embodiment shown here, which can be connected to the base body 2 by means of a locking device 8.

[0059] In the embodiment shown here, the base body 2 is connected to a handling device 400, or is provided by a part of this handling device 400.

[0060] In the illustrated embodiment, the handling device 400 has a battery 401, so that the assembly device 1 can also be operated mobilely without a cable and / or hose-bound power supply.

[0061] Within the base body 2, an actuator assembly 7 is arranged, which in the embodiment shown here is also provided by the handling device 400. In this embodiment, the actuator assembly comprises a pressure cylinder 9 or a hydraulic system 9. In other embodiments, however, instead of the pressure cylinder or the hydraulic system, a worm drive 10 and / or a threaded rod 11 and / or other devices for generating a linear motion may be provided additionally or alternatively.

[0062] All necessary components for extending the pressure cylinder 9 within the base body 2, such as the electric motor, hydraulic pump, control valves, etc., are arranged here in the handle 402 of the handling device 400, whereby the pressure cylinder 9 can be extended by means of an actuating element 403. In the embodiment shown here, the handle 402 thus provides the drive or the housing for the drive for the actuator device 7.

[0063] The assembly device 1 further comprises a pipe assembly 5, which can be slid over the base body 2, at least in sections. A clearance 12 is provided in the base body 2, through which the actuator assembly 7 can enter into operative contact with the pipe assembly 5 slid onto the base body 2.

[0064] The pipe assembly 5 has a clearance 13, which corresponds to the clearance 12 in the base body 2. When the pipe assembly 5 is slid over the base body 2, a operative connection between the actuator assembly or pressure cylinder 9 and the pipe assembly 5 can be established by means of a coupling element 14, in the embodiment shown here by means of a bolt 22. When the actuator assembly 7 is actuated or the pressure cylinder 9 is extended, the pipe assembly 5 is pushed forward via the coupling element 14.

[0065] The pipe assembly 5 comprises a system section 6, with which, for example, a bearing 100 can be pressed in, or which bears against the housing part 300 when a shaft is pulled in. Depending on the embodiment, a fitting 20 may be provided, which bears against the system section 6. Different contours and cross-sections or diameters can be adapted via such a fitting 20.

[0066] The receiving device 4 serves to receive the counterpart 3, which in particular functions as a tie rod. The counterpart 3 and / or the receiving device 4 have a connecting device 19, which enables a quick and reliable connection between the counterpart 3 and the base body 2 via the receiving device 4. In the illustrated embodiment, the counterpart 3 can simply be hooked into the connecting device 19 with a correspondingly designed connecting device 19 in the receiving device.

[0067] In the illustrated embodiment, the pipe assembly 5 has different inner diameters. The diameter of the receiving device 4 is larger than the diameter of the base body 2 in this embodiment. To allow the pipe assembly 5 to be moved over both the base body 2 and the receiving device 4, the pipe assembly 5 is first slid over the base body 2. The receiving device 4 is then inserted into a corresponding opening in the base body 2. The locking device 8 can then be inserted through the opening 23 in the pipe assembly 5, thus securely connecting the receiving device 4 to the base body 2. The pipe assembly 5 is also secured against unintentional detachment.

[0068] In the embodiment shown here, the counterpart 3 comprises a plate 17, which acts as a tie rod against the housing part 300 when a component is inserted. Furthermore, the counterpart 3 here comprises a centering projection 26, by means of which the counterpart 3 can be inserted into the opening 301 in a defined manner.

[0069] Furthermore, in the embodiment shown here, the centering projection 26 serves as a stop or depth stop 27. This stop 27 ensures that a component 100 or bearing can be mounted in a defined manner, since the press-in depth is limited.

[0070] In Figure 1It is also shown 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 placed or slid onto the centering aid 28, which is guided through the opening 301. The component 100, thus pre-positioned, can then be pressed in using the assembly device 1.

[0071] In Figure 2 The diagram shows, purely schematically, how a component 100, here a bearing 100, is pressed in. For this purpose, the bearing 100 is positioned in front of one side of the opening 301, with the counterpart 3, in the embodiment shown here, being inserted from the other side of the opening 301 into the housing part 300 through the opening 301 and the bearing 100.

[0072] The counterpart 3 is then hooked into the receiving device 4, for which a fitting 20 is provided that adapts the system section 6 to the size of the bearing 100. To allow the counterpart 3 to be inserted into the receiving device 4 despite the fitting 20, a corresponding clearance 21 is provided in the fitting 20. To prevent the fitting 20 from falling off the pipe assembly 5, a locking device 24 is also provided, which here is designed as a spring-loaded pressure piece. Other locking devices can also be used effectively and appropriately to securely hold the fitting 20 on the pipe assembly 5.

[0073] When the actuator 7 is actuated, in the embodiment shown here the pressure cylinder 9 is extended forward, i.e., in the direction of the receiving device 4, whereby the coupling of the actuator 7 via the coupling element 14 pushes the pipe assembly 5 forward. This displaces the pipe assembly 5 and the base body 5 or the receiving device 4 relative to each other, thus changing the distance between system section 6 and the receiving device 4.

[0074] In the embodiment shown here, the pipe assembly 5 moves forward over the receiving device 4, thus reducing the distance between the system section 6 and the counterpart 3 or the plate 17 of the counterpart 3. This exerts a pressing force on the bearing 100, causing it to be pushed into the opening 101 of the housing part 300.

[0075] In Figure 3A purely schematic representation of an assembly device 1 according to the invention is shown from above. Here, too, it can be seen that the counterpart 3 is received in the receiving device 4 by means of a connecting device 19. Furthermore, it can be seen that a clearance 13 is provided in the pipe device 5, which has a first engagement section 15 and a second engagement section 16. This provides a type of bayonet adjustment.

[0076] This serves to increase the stroke of the pipe assembly 5 in the embodiment shown here in two stages if the available stroke of the actuator assembly 7 or the pressure cylinder 9 is insufficient. For this purpose, the pipe assembly 5 is first brought into contact with the coupling element 14 via the first engagement section 15. The actuator assembly 7 is then actuated, causing the pressure cylinder 9 to extend.

[0077] If the stroke of the pressure cylinder 9 is insufficient, the pressure cylinder or the actuator assembly 7 can be retracted, which also retracts the coupling element 14. In the embodiment shown here, this retraction is effected by a spring return mechanism.

[0078] The pipe assembly 5 can now be rotated so that the second engagement section 16 comes into contact with the coupling element 14. The actuator 7 can then be actuated again, so that, due to the design of the pipe assembly 5 with one engagement section 15 and a second engagement section 16, twice the stroke is available. Depending on the configuration, even more engagement sections can be used to achieve the desired stroke or displacement of the pipe assembly 5.

[0079] In the Figures 4 to 6The purely schematic sectional views show the pressing of a bearing 100 into an opening 301 in a housing part 300. The bearing 100 is located in Figure 4 even before opening 301. In the two views according to the Figures 5 and 6 The bearing 100 is already fully pressed into the opening 301 of the housing part 300.

[0080] The position of the pipe assembly 5 relative to the receiving device 4 can be determined in particular from the position of the coupling element 14 and the system section 6. As shown in the Figures 5 and 6 As can be seen, compared to the initial position of the assembly device 14, the pipe assembly 5 is pushed forward beyond the receiving device 4. This changes the distance between the system section 6 and the plate 17 of the counterpart 3, which serves as a tie rod. This ensures that the bearing is optimally pressed into the opening 301.

[0081] Since the movement of the pipe assembly 5 is effected by means of a handling device, and specifically by means of hydraulics, a particularly simple and quick pressing in of a bearing or component 100 is achieved. Cumbersome handling of threaded rods and nuts is not necessary. Driving in the bearing is also unnecessary, which is relatively difficult because one must work very carefully to avoid damaging the bearing.

[0082] In Figure 7 A further embodiment of an assembly device 1 according to the invention is shown purely schematically in a perspective exploded view. In contrast to the embodiment according to Figure 1 The counterpart 3 here does not have a plate 17 or abutment, but rather a fastening device 18.

[0083] Such an embodiment of an assembly device 1 according to the invention, with a corresponding counterpart 3, can be used in particular for inserting components 100 such as shafts 200. However, components can also be pushed over other components using such an assembly device 1 and / or pushed over other components and simultaneously and / or subsequently pressed into an opening.

[0084] In Figure 8 The drawing-in of a component 200 or a shaft 200 into an opening 301 of a housing part 300 is shown purely schematically. The counterpart 3 is stably connected to the shaft 200 by means of the fastening device 18.

[0085] The counterpart 3 is then connected to the receiving device 4 by means of the connecting device 19.

[0086] When the actuator device 7 is actuated, the pipe device 5 is also pushed forward over the receiving device 4 in the embodiment shown here, whereby in such a design the system section 6 or the molded part 20 is supported against the housing part 300 and the shaft 200 is pulled through the opening 301.

[0087] In the embodiment shown here, both the pipe assembly 5 and the fitting 20 are adapted in such a way that the shaft 200 can be drawn into the fitting 20 and the pipe assembly 5 at least section by section.

[0088] In the Figures 9 to 14 The diagram, shown purely schematically in three different views, illustrates how a wave 200 is drawn into the opening.

[0089] In Figure 9Figure 1 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 device 4.

[0090] In Figure 10 is a sectional view from above through the cutting plane AA in Figure 9 shown purely schematically. Here you can see the counterpart 3 connected to the shaft 200, which is screwed into the shaft 200 by means of a fastening device 18.

[0091] The counterpart 3 is guided through the opening 301 and inserted into the receiving device 4, so that the counterpart 3 is firmly connected to the base body 2. When the actuator 7 is actuated, the pipe assembly 5 is pushed forward. Since the system section 6 or the fitting 20 is supported against the housing part 300, the relative movement of the pipe assembly 5 to the receiving device 4 or to the base body 2 draws the shaft 200 into the opening 301, thereby drawing the shaft or the counterpart 3 into the pipe assembly 5.

[0092] This is in the Figures 11 and 12 depicted, whereby in Figure 12 a sectional view from above through the section plane BB in Figure 11 As shown. Here it can be seen that the counterpart 3 has already been partially drawn through the opening 301 and is entering the pipe assembly 5 or passing through the fitting 20.

[0093] In the Figures 13 and 14The diagram shows, purely schematically, that the shaft is completely pulled through the opening 301. For this purpose, the pipe assembly 5 in the embodiment shown here is repositioned by means of a bayonet-type adjustment, so that the coupling element 14 is no longer engaged with the first engagement section 15, but with the second engagement section 16.

[0094] For this purpose, the actuator device 7 was first retracted, followed by the rotation of the pipe device 5, which was then manually moved and rotated so that the coupling element 14 engages with the second engagement section.

[0095] When the actuator assembly 7 is extended again, the pipe assembly 5 is advanced further, so that the shaft 200 is drawn further or completely through the opening 301, whereby in Figure 14It can be seen that the counterpart 3 is now completely arranged in the pipe assembly 5, with the shaft 200 also being drawn into the pipe assembly 5 and through the fitting 20.

[0096] In Figure 15 The figure shown is a purely schematic perspective view of an exemplary embodiment of a pipe assembly. The bayonet adjustment, by means of which the first engagement section 15 or the second adjustment section 16 can be brought into operative contact with the actuator assembly 7, is also visible here.

[0097] In the Figures 16 and 17 Figure 1 shows a further embodiment of an assembly device 1 according to the invention, purely schematically. In the embodiment shown, however, no fitting 20 is provided, but the section 6 of the pipe assembly 5 serves directly as the force-transmitting section or press section.

[0098] Another difference from the previously shown embodiments is that the clearance 13 in the pipe assembly 5 is not closed. Here, the first engagement section 15 is provided in the clearance 13. Should a greater stroke or further displacement of the pipe assembly 5 be necessary, the actuator 7 can be retracted, whereby the pipe assembly 5 can also be rotated, with the coupling element 14 then pressing against the pipe assembly 5 outside the clearance 13, so that the edge 25 of the pipe assembly 5 provides the second engagement section 16.

[0099] Depending on the design of the mounting device 1 or the actuator assembly 7 and the pipe assembly 5, adjustment between a first and a second or further engagement section 15, 16 may not be necessary. In that case, the clearance 13 in the pipe assembly 5 can, for example, also be provided as a simple through-hole. Reference symbol list
