The appearance of the phrase in various places in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments.

[0032] In the description of this application, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", and "attached" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection, or an indirect connection through an intermediate medium, or it can be the internal communication of two elements.

[0034] In the embodiments of the present application, the same reference numerals represent the same components, and for the sake of brevity, detailed descriptions of the same components are omitted in different embodiments. It should be understood that the thickness, length, width and other dimensions of various components in the embodiments of the present application shown in the drawings, as well as the overall thickness, length, width and other dimensions of the integrated device are only exemplary descriptions and should not constitute any limitation to the present application.

[0036] In the description of the present invention, a first feature being “above” or “below” a second feature may include that the first and second features are directly in contact with each other, or may include that the first and second features are not in direct contact but are in contact with each other via another feature therebetween.

[0037] In the description of the present invention, a first feature “above”, “over” and “above” a second feature includes the first feature being directly above and obliquely above the second feature, or simply means that the first feature is horizontally higher than the second feature.

[0038] The term "plurality" used in the present application refers to two or more (including two).

[0039] First of all, it should be pointed out that in the technical solution of integrating the motor 300 with the rear axle or the front axle, the motor 300 and the rear axle, or the motor 300 and the front axle constitute the drive axle 200 assembly, and when the drive axle 200 assembly is assembled, it is necessary to connect the motor shaft of the motor 300 with the drive shaft of the drive axle 200. The two can be connected by a spline structure or transmitted by gear meshing. Regardless of whether the spline structure is used for connection or the gear meshing is used for transmission, it is necessary to adjust the relative position of the rear axle and the motor 300 during the assembly process. In the prior art, it is difficult to align the motor shaft and the drive shaft, or it is difficult to move the motor 300 to the expected assembly position, resulting in greater assembly difficulty and lower assembly efficiency.

[0040] At the same time, it is understandable that the power connection between the motor shaft and the drive shaft requires lubrication by a lubricating medium to reduce wear between the motor shaft and the drive shaft, extend service life, and improve the working stability and safety of the drive axle 200 assembly.

[0041] However, the viscosity of the lubricating medium is relatively high. After the lubricating medium is set in the spline area of ​​the motor shaft and the spline area of ​​the drive shaft, the assembly resistance between the two is relatively large, which will also increase the difficulty of assembly and reduce the assembly efficiency.

[0042] Based on this, the present application proposes a drive axle tooling 100, which can reduce assembly difficulty and improve assembly efficiency.

[0043] Reference below Figure 1-Figure 5 A drive axle tool 100 according to an embodiment of the present invention is described.

[0044] like Figure 1 and Figure 2 As shown, the drive axle tooling 100 according to the embodiment of the present application includes: a stand 10, a bracket assembly 20, a tray assembly 30 and an assembly assembly 40.

[0045] The bracket assembly 20 is disposed on the platform 10 and is suitable for lifting the drive axle 200. The tray assembly 30 is disposed on the platform 10, and the motor 300 is movably disposed on the tray assembly 30. The assembly assembly 40 is disposed on the platform 10 and is suitable for pushing the motor 300 to move in the tray assembly 30 so as to be assembled to the drive axle 200.

[0046] Specifically, the bracket assembly 20 can lift and position the drive axle 200, so that the drive axle 200 is in the expected installation position and maintains a relatively static state, and the tray assembly 30 is set on the stand 10, and the motor 300 is movably set on the tray assembly 30, so that the motor 300 can be moved to the expected installation position by moving the motor 300, thereby facilitating the assembly of the motor 300 and the drive axle 200, improving the assembly accuracy, and reducing the difficulty of assembly.

[0047] It can be understood that the motor 300 is movably arranged on the tray assembly 30 in two situations. One situation is the adjustment process before assembly. In this process, the position of the motor 300 is adjusted to move the motor 300 to the expected installation position. The other situation is that after adjusting to the expected installation position, the motor 300 is further switched between the first position and the second position, the first position being the expected installation position, and the second position being the assembled position, that is, the assembly of the motor 300 is completed by switching the motor 300 between the first position and the second position. The movement of the motor 300 to the expected installation position can be a synchronous movement of the motor 300 and the tray assembly 30, and the switching of the motor 300 between the first position and the second position can be a separate movement of the motor 300 relative to the tray assembly 30 or a synchronous movement.

[0048] Furthermore, if Figure 4 As shown, the assembly component 40 includes a push block 41 movably disposed on the stand 10 and adapted to push the motor 300 to move toward the axle housing of the drive axle 200 .

[0049] It should be pointed out that lubricating media are provided on both the motor shaft and the drive shaft. The viscosity of the lubricating media is relatively high, resulting in relatively large assembly resistance between the motor 300 and the drive axle 200. Excessive assembly resistance increases the difficulty of assembly and affects assembly efficiency.

[0050] Based on this, the present application sets up an assembly component 40, which can push the motor 300 from the first position to the second position to complete the assembly, making the assembly of the motor 300 more labor-saving, reducing the difficulty of assembly, and improving the assembly efficiency.

[0051] According to the drive axle tooling 100 of the embodiment of the present application, by setting the assembly component 40, the push block 41 of the assembly component 40 can push the motor 300 to move from the first position to the second position, so as to overcome the greater assembly resistance through the assembly component 40, reduce the assembly difficulty, and improve the assembly efficiency.

[0052] See also Figure 4 As shown, according to some embodiments of the present application, the assembly component 40 further includes: a push rod 42 , which is dynamically connected to the push block 41 and is suitable for driving the push block 41 to move toward or away from the motor 300 .

[0053] Specifically, the push rod 42 is connected to the push block 41, or the push rod 42 and the push block 41 are connected through a transmission structure, so that the push rod 42 pushes the push block 41, thereby realizing the assembly of the motor 300. Through the setting of the push rod 42, the force arm of the assembly component 40 can be increased, so that the assembly component 40 can be more labor-saving during the assembly process and the assembly efficiency is higher.

[0054] exist Figure 4In the specific embodiment shown, the assembly component 40 further includes: a mounting frame 43 , the mounting frame 43 is connected to the tray assembly 30 , and the push rod 42 is disposed on the mounting frame 43 .

[0055] Specifically, the mounting frame 43 is disposed on the tray assembly 30, and can be disposed on the first tray 321, the second tray 322 or the third tray 323 of the tray group 32, or can be disposed on the stand 10, preferably on the first tray 321, so that the assembly component 40 can move synchronously with the tray assembly 30, and then during the assembly of the motor 300, there is no need to further adjust the relative position between the push block 41 of the assembly component 40 and the motor 300, so as to simplify the assembly structure, reduce the adjustment actions during the assembly process, and improve the convenience of assembly.

[0056] In some embodiments, the push rod 42 may include: a first rod portion 421 and a second rod portion 422, one end of the first rod portion 421 is connected to the mounting frame 43, the free end of the second rod portion 422 is connected to the push block 41, and the first rod portion 421 and the second rod portion 422 are threadedly matched to make the length of the push rod 42 adjustable.

[0057] Specifically, the first rod portion 421 and the second rod portion 422 are configured to be threadedly matched so that the overall length of the push rod 42 is adjustable, so that the length of the push rod 42 can be adjusted based on assembly requirements to adapt to the assembly between drive axles 200 and motors 300 of different specifications.

[0058] It should be pointed out that the first rod portion 421 and the second rod portion 422 can be constructed as a threaded fit to make the length adjustable. The first rod portion 421 and the second rod portion 422 can also be constructed as a telescopic structure to achieve length adjustment of the push rod 42. After the first rod portion 421 and the second rod portion 422 are adjusted to a suitable length, the relative position of the first rod portion 421 and the second rod portion 422 can be locked by a locking pin or other structure.

[0059] like Figure 4 As shown, the first rod portion 421 is connected to the mounting bracket 43 via a sliding sleeve 44 .

[0060] That is to say, a sliding sleeve 44 is provided on the mounting frame 43, and one end of the first rod portion 421 can be slidably set in the sliding sleeve 44, and the sliding sleeve 44 is fixed on the mounting frame 43, so that the first rod portion 421 can be slidably set on the mounting frame 43, and the driving of the push block 41 can be achieved by adjusting the relative position between the sliding end of the first rod portion 421 and the mounting frame 43. Through the setting of the sliding sleeve 44, the friction loss between the first rod portion 421 and the mounting frame 43 can be reduced, which can extend the service life of the drive axle tooling 100 and reduce abnormal noise during the assembly process, thereby improving the use experience.

[0061] Furthermore, the assembly component 40 also includes a push handle 45 , which is disposed on the mounting frame 43 and is dynamically connected to the push rod 42 .

[0062] Specifically, the push handle 45 can be constructed as a wrench, handwheel or other structure. By pulling or rotating the push handle 45, the push rod 42 drives the push block 41 to move. The operation difficulty of the assembly component 40 is lower, the assembly convenience is higher, and the assembly action is more labor-saving.

[0063] It is understandable that in the embodiment where the push handle 45 is configured as a wrench, the push handle 45 is rotatably disposed on the mounting frame 43, and the rotating end of the push handle 45 is configured as a cam structure and pushes against the first rod portion 421 to drive the push block 41 to move.

[0064] That is, by pulling the push handle 45, the push handle 45 is configured as a cam structure, and different positions of the rotating end push against the first rod portion 421, so that the first rod portion 421 extends out of the sliding sleeve 44 or retracts into the sliding sleeve 44, reducing the difficulty of operation.

[0065] It should be pointed out that the cam structure can make the rotating end directly formed as a cam, or the rotating end can be formed as a mechanical structure equivalent to the cam, that is, a mechanical structure that can realize the linear reciprocating motion of the push rod 42. Both are optional structural forms of the rotating end of the push handle 45 of the present application, and the present application does not make specific limitations.

[0066] like Figure 4 As shown, according to some embodiments of the present application, the mounting frame 43 includes: a first plate 431 and a second plate 432 which are arranged at an angle, and the first plate 431 is fixed to the tray assembly 30 , and the second plate 432 is connected to the push rod 42 .

[0067] Specifically, the first plate 431 and the second plate 432 are arranged at right angles, one end of the first plate 431 is connected to the first tray 321 of the tray group 32, and the other end is connected to one end of the second plate 432, the other end of the second plate 432 extends upward, and the other end of the second plate 432 is provided with a push rod 42, a sliding sleeve 44 and a pull handle.

[0068] In this way, on the one hand, through the setting of the mounting frame 43, the assembly component 40 and the tray component 30 can be moved synchronously, the adjustment steps can be simplified, the assembly steps can be simplified, so as to reduce the difficulty of assembly and improve the assembly efficiency; on the other hand, the push rod 42, the push block 41 and other structures can be closer to the motor 300 in space, which is convenient for operation, and the probability of interference between the bracket component 20, the tray component 30 and the assembly component 40 during the assembly process can be avoided, thereby further improving the convenience of assembly.

[0069] Furthermore, a reinforcing plate 433 is provided between the first plate 431 and the second plate 432. Thus, the structural strength and reliability of the mounting frame 43 can be improved, the fixing stability and reliability of the assembly component 40 on the tray component 30 can be improved, and the service life of the assembly component 40 of the drive axle 200 can be extended.

[0070] like Figure 3 As shown, the tray assembly 30 of the present application can drive the motor 300 to move relative to the stand 10 and the drive bridge 200, and can move to the expected installation position.

[0071] Specifically, the tray assembly 30 of the present application includes: a motor bracket 31 and a tray group 32, the motor bracket 31 is arranged on the tray group 32, and the tray group 32 is adjustable in the X-direction, Y-direction and Z-direction relative to the stand 10 so that the motor shaft of the motor 300 is aligned with the drive shaft of the drive axle 200.

[0072] That is to say, the motor bracket 31 is set on the tray group 32, and the tray group 32 can realize position adjustment in the height direction and the X and Y directions in the horizontal plane, so as to adjust the relative position of the motor bracket 31 through the tray group 32, so that the motor 300 set above the motor bracket 31 moves to the expected installation position, and in the expected installation position, the motor shaft of the motor 300 can be aligned with the drive shaft of the drive axle 200, so as to reduce the difficulty of assembly and improve the assembly efficiency.

[0073] It should be pointed out that the alignment of the motor shaft and the drive shaft can be, in an embodiment where the motor shaft and the drive shaft are connected by a spline structure, the motor shaft and the drive shaft reach a concentric position, and in an embodiment where the motor shaft and the drive shaft transmit power through a gear structure, the motor shaft and the input gear reach a concentric position, and the input gear is integrated in the bridge housing of the drive axle 200.

[0074] According to the drive axle tooling 100 of the embodiment of the present application, by setting a tray assembly 30, the tray assembly 30 is suitable for driving the motor 300 to adjust its position in the height direction and the horizontal plane, which can reduce the difficulty of aligning the motor 300 with the drive axle 200, thereby reducing the difficulty of assembly, improving assembly efficiency, and reducing assembly costs.

[0075] like Figure 3 As shown, according to some embodiments of the present application, the tray group 32 includes: a first tray 321 , and the first tray 321 is movably disposed on the stand 10 along the Z direction through a lifting and adjusting assembly 33 .

[0076] Specifically, the lifting and adjusting component 33 is connected to the first tray 321, and the lifting and adjusting component 33 is arranged on the stand 10, and the first tray 321 is arranged on the lifting and adjusting component 33. By adjusting the lifting and adjusting component 33, the relative position of the first tray 321 in the height direction can be achieved, and then the position adjustment of the tray assembly 30 as a whole in the height direction can be achieved, which can reduce the difficulty of height adjustment of the motor 300, reduce workload, and improve assembly efficiency.

[0077] See also Figure 3 As shown, further, a guide assembly 34 is provided between the first tray 321 and the stand 10 , and the guide assembly 34 is suitable for guiding the Z-direction movement of the first tray 321 .

[0078] Specifically, the guide assembly 34 can be constructed as a plurality of guide columns, which can be slidably disposed on the stand 10 and have their top ends fixed to the first tray 321, or the guide columns are fixed to the stand 10 and slidingly cooperate with the first tray 321, so as to guide the movement of the first tray 321 through the guide columns, thereby improving the movement accuracy of the first tray 321, reducing the movement of the first tray 321 during movement, and improving the adjustment accuracy.

[0079] Exemplarily, the number of the guide posts is four, and the four guide posts are respectively disposed on four corner areas of the first tray 321 .

[0080] exist Figure 3 and Figure 5 In the specific embodiment shown, further, the lifting and adjusting assembly 33 includes: a lifter 331, an adjusting rod 332 connected to the lifter 331 by power, and an adjusting handle 333 for driving the adjusting rod 332 to move, and the adjusting handle 333 is arranged on the lateral edge of the platform 10.

[0081] Specifically, the lifter 331 can be constructed as a hydraulic lifting mechanism, a screw nut lifting mechanism, a piston connecting rod lifting mechanism, etc. The adjusting rod 332 is used to drive the lifter 331 to achieve lifting, and the adjusting handle 333 is used for the operator to operate to drive the adjusting rod 332. This can not only reduce the operating difficulty of the lifting and adjusting component 33, improve the operating convenience, and thus improve the assembly efficiency, but also the lifter 331 can make the height adjustment process of the motor 300 more labor-saving, thereby improving the operating convenience and the use experience.

[0082] Exemplarily, the lifter 331 is constructed as a screw-nut lifting mechanism, the adjusting rod 332 is engaged with the lifter 331, and the adjusting handle 333 is constructed as a handwheel. The rotation of the handwheel can drive the adjusting rod 332 to rotate. The adjusting rod 332 rotates clockwise to raise the lifter 331 and synchronously drives the first tray 321 to rise. The adjusting rod 332 rotates counterclockwise to lower the lifter 331 and synchronously drives the first tray 321 to descend.

[0083] Furthermore, the adjusting rod 332 and the lifter 331 are dynamically connected via a universal joint 334 .

[0084] That is to say, a universal joint 334 is provided between the adjusting rod 332 and the lifter 331, which can realize variable-angle power transmission and is used in positions where the direction of the transmission axis needs to be changed. It can make the power transmission stability between the lifter 331 and the adjusting rod 332 higher, and the working stability of the lifter 331 higher, thereby making the working stability and reliability of the drive axle tooling 100 higher.

[0085] like Figure 5 As shown, the lifter 331 includes a power input end 3311 and a power output end 3312 , the power input end 3311 is power-connected to the power output end 3312 , the power input end 3311 is connected to the adjustment rod 332 , and the power output end 3312 is connected to the tray assembly 32 .

[0086] Specifically, the power input end 3311 and the power output end 3312 can be constructed as a screw nut transmission to drive the tray group 32 to move through meshing transmission, or can be constructed as an oil transmission, that is, the lifter 331 has a cylinder body, and a pressure medium is arranged in the cylinder body, and the power output end 3312 is constructed as a hydraulic rod. The power input end 3311 rotates under the drive of the adjustment rod 332 to adjust the cylinder body volume. The cylinder body volume changes to generate pressure, thereby pushing the power output end 3312 up or down to drive the tray group 32 to move. Figure 3 As shown, further, the lifting and lowering adjustment assembly 33 also includes: a locking member 335 , which is disposed on the stand 10 and is suitable for unlocking or locking the adjustment rod 332 .

[0087] Specifically, the locking member 335 can be fixed on the stand 10 by a fixing block, and the locking member 335 can have a locking structure such as a locking pin. After the adjusting rod 332 moves to a suitable position, that is, after the motor 300 is adjusted to a suitable height, the adjusting rod 332 is locked by a locking structure such as a locking pin, so that the adjusting rod 332 is fixed at the current angle.

[0088] In this way, the stability of the lifting and adjusting assembly 33 can be improved. After being adjusted to the appropriate position, the adjustment rod 332 can be prevented from changing position, thereby preventing the motor 300 from changing position, thereby improving the adjustment reliability and ensuring that there will be no position changes in the height direction during the subsequent assembly of the motor 300. It can also improve the assembly accuracy and reduce the difficulty of assembly.

[0089] According to some embodiments of the present application, the tray group 32 also includes: a second tray 322 and a third tray 323, the second tray 322 slidingly cooperates with the first tray 321, the third tray 323 slidingly cooperates with the second tray 322, and one between the second tray 322 and the third tray 323 and between the first tray 321 and the second tray 322 is provided with an X-guide rail, and the other is provided with a Y-guide rail, so that the position of the motor bracket 31 in the X direction and the Y direction can be adjusted.

[0090] Exemplarily, an X-guide rail may be provided between the first tray 321 and the second tray 322, a Y-guide rail may be provided between the second tray 322 and the third tray 323, and the motor bracket 31 may be provided on the third tray 323, so that adjustment in the X and Y directions may be achieved; or a Y-guide rail may be provided between the first tray 321 and the second tray 322, an X-guide rail may be provided between the second tray 322 and the third tray 323, and the motor bracket 31 may be provided on the third tray 323, so that adjustment in the X and Y directions may be achieved.

[0091] In this way, the tray group 32 includes: a first tray 321, a second tray 322 and a third tray 323. The first tray 321 can realize height adjustment, and the second tray 322 and the third tray 323 can realize X-axis adjustment and Y-axis adjustment respectively, so that the motor 300 has more adjustment freedom, the adjustment difficulty of the motor 300 is lower, the alignment difficulty between the motor 300 and the drive axle 200 is lower, the assembly difficulty is lower, and the assembly efficiency is higher.

[0092] See also Figure 3 As shown, in some embodiments, the motor bracket 31 includes: a bracket plate 311 and a bracket body 312, the bracket plate 311 is fixedly connected to the tray assembly 32, an oblong hole is provided on the bracket plate 311, and the bracket body 312 is set on the bracket plate 311 by a fastener penetrating the oblong hole.

[0093] Specifically, the bracket plate 311 is fixedly connected to the third tray 323, or the bracket plate 311 and the third tray 323 are integrated, and an oblong hole can be set on the bracket plate 311, and the bracket body 312 is connected to the bracket plate 311 by fasteners, and the fasteners are penetrated by the oblong holes, so that the relative position between the bracket plate 311 and the bracket body 312 is adjustable, and the position adjustment of the tray group 32 is combined with the overall adjustment stroke of the bracket assembly 20 to make it larger, and the adaptation range of the drive axle tooling 100 is larger, which can be applicable to the assembly of more types of drive axles 200 and motors 300, thereby improving the applicability of the drive axle tooling 100.

[0094] It is understandable that the movement stroke of the motor 300 from the first position to the second position should be consistent with the adjustable stroke of the bracket body 312 in the oblong hole, or the adjustment stroke should be slightly larger than the movement stroke from the first position to the second position to facilitate the assembly of the motor 300.

[0095] like Figure 1 and Figure 2 As shown, according to some embodiments of the present application, the bracket assembly 20 includes a plurality of brackets 21 , and the plurality of brackets 21 are all disposed on the platform 10 and are suitable for placing the drive axle 200 horizontally.

[0096] Specifically, the bracket 21 may include a rod body and a lifting portion arranged at the free end of the rod body, one end of the rod body is connected to the stand 10, and a plurality of fixing portions may be arranged on the stand 10. The rod body may be selectively arranged on different fixing portions to adapt to drive axles 200 of different specifications and sizes. The height adjustment between the rod body and the lifting portion may be achieved by setting a gasket to adapt to drive axles 200 with different assembly height and size requirements. A U-shaped positioning surface may be arranged on the lifting portion to position the drive axle 200, and the shape of the positioning surface may be adaptively set according to the outer contour of the drive axle 200, which will not be repeated here.

[0097] It is understandable that flexible structures can be provided on the supporting portion and the supporting surface of the motor bracket 31 for positioning and buffering to avoid scratching the drive axle 200 or the motor 300 during assembly. The flexible structure can be constructed as a pad, which can be a rubber pad, a nylon pad, etc.

[0098] Combination Figure 1 and Figure 2 As shown, the assembly process of the drive axle 200 of the embodiment of the present application is as follows:

[0099] First, the drive axle 200 is placed on the bracket assembly 20 , and the drive axle 200 is positioned by a plurality of brackets 21 .

[0100] Furthermore, the motor 300 is set on the motor bracket 31, and the height position of the motor 300 is adjusted by adjusting the lifting adjustment component 33. The relative position between the second tray 322 and the first tray 321 and the relative position between the second tray 322 and the third tray 323 are adjusted so that the motor 300 reaches the expected installation position.

[0101] Finally, the motor 300 is pushed from the first position (i.e., the expected installation position) to the second position (i.e., the assembled position) by the push block 41 of the assembly component 40 to complete the assembly of the motor 300 and the drive axle 200, thereby reducing the assembly difficulty and improving the assembly efficiency.
