They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, the above terms should not be construed as limitations on this application.

[0021] It is understood that the term "a" should be understood as "at least one" or "one or more", that is, in one embodiment, the number of an element can be one, while in another embodiment, the number of the element can be multiple, and the term "a" should not be understood as a limitation on the number.

[0022] refer to Figures 1 to 3 A preferred embodiment of the fixture for placing an input shaft assembly according to this application will be described in detail below. The fixture includes a side support 10 and a base 20. The side support 10 has at least one set of first insertion holes 101. The base 20 extends horizontally from the lower end of the side support 10, and the length direction of the base 20 is parallel to the orientation of the first insertion holes 101. The dimensions of the first insertion holes 101 are adapted to the shaft dimensions of the input shaft assembly, and the base 20 is capable of supporting the planetary gear set of the input shaft assembly.

[0023] An input shaft assembly is supported by a fixture with its shaft inserted into a first socket 101 and its planetary arrangement placed on the upper surface of the base 20. This fixture provides stable support for the input shaft assembly during surface quality inspection by rotating it, preventing it from rolling and colliding with surrounding components, thus avoiding damage. It also prevents foreign matter from adhering to the input shaft assembly during rolling, which could affect subsequent inspections. Furthermore, this application standardizes operator behavior, reduces safety risks during operation, improves the overall safety of the working environment, enhances operational convenience, improves assembly quality and overall work efficiency, and optimizes the operational process. This application also has the advantages of simple structure, small size, and light weight, making it easy to carry and store, and suitable for use in confined spaces.

[0024] In one embodiment, two sets of the first socket 101 are provided, and the two sets of the first socket 101 are arranged back to back. The side support 10 is located in the middle of the base 20. In this way, the fixture for placing the input shaft assembly can simultaneously support two input shaft assemblies, allowing multiple workers to perform inspection operations at the same time, thus improving work efficiency.

[0025] Preferably, each group has one first socket 101, and the first socket 101 can be designed to be of different sizes so that the placement fixture for the input shaft group with different sizes of the first socket 101 can support the input shaft groups with different shaft diameters and lengths, thereby meeting the actual placement requirements.

[0026] In one embodiment, each group of first sockets 101 is provided with a plurality of first sockets 101, and the plurality of first sockets 101 are distributed at vertical intervals to accommodate input shaft groups with different radial dimensions of the planetary gear set on the shaft portion, thereby satisfying the requirement to accommodate input shaft groups with different planetary gear set sizes.

[0027] Preferably, the side support 10 includes a side support body 11 and a plug-in portion 12. The side support body 11 is mounted on the base 20, and the plug-in portion 12 is mounted on the surface of the side support body 11. The first insertion hole 101 is formed in the plug-in portion 12.

[0028] Preferably, the plug portion 12 is detachably mounted to the side support body 11. This allows for greater flexibility in use when input shaft assemblies with different shaft diameters need to be placed; simply replace the plug portion 12 with one of different sizes in the first socket 101.

[0029] refer to Figures 2 to 3 The plug-in part 12 has at least one first mounting hole 1201, and the side support body 11 has at least one first mating hole 1101. The plug-in part 12 is assembled to the side support body 11 in such a way that each of the first mounting holes 1201 corresponds to a first mating hole 1101, and either one is first penetrated by a bolt while the other is threadedly engaged with the corresponding bolt.

[0030] Preferably, there are four of each of the first mounting holes 1201 and the first mating holes 1101, and the four first mounting holes 1201 are spaced apart in pairs. The plug-in part 12 is assembled to the side support body 11 with four bolts in such a way that the four first mounting holes 1201 correspond to the four first mating holes 1101 respectively, so as to ensure that the plug-in part 12 is firmly assembled with the side support body 11.

[0031] In one embodiment, when the first insertion hole 101 is provided, the first mounting hole 1201 and the first mating hole 1101 are both provided. The first mounting hole 1201 is coaxial with the first insertion hole 101 and is located at the center of the insertion part 12, so as to prevent the insertion part 12 from deflecting when the connection is loose, causing the position of the first mounting hole 1201 to change, which is not conducive to the subsequent support of the input shaft assembly.

[0032] refer to Figures 1 to 3The base 20 includes a main body 21 and at least one support part 22. The main body 21 is mounted on the side support body 11 of the side support member 10. The support part 22 is disposed on the upper surface of the main body 21 and is used to support the planetary gear set of the input shaft assembly.

[0033] It is worth mentioning that, in the horizontal direction perpendicular to the axis of the first socket 101, the size of the support 22 is smaller than the size of the planetary gear set of the input shaft assembly, so as to minimize the contact area between the planetary gear set and the support 22 when the input shaft assembly is placed, and greatly reduce the possibility of the planetary gear set being contaminated.

[0034] Preferably, the support portion 22 has a set of second insertion holes 201 with a predetermined depth in the vertical direction. The second insertion holes 201 are used to insert the shaft portion of the input shaft assembly so as to disassemble and assemble the input shaft assembly. This avoids the situation where the parts set on the shaft portion directly contact the table surface and adhere foreign objects during the disassembly and assembly process, thus ensuring the cleanliness of the parts.

[0035] Preferably, a set of second sockets 201 is provided, and the second sockets 201 can be designed to be of different sizes so that the placement fixture for the input shaft assembly with different sizes of the second sockets 201 can support input shaft assemblies with different shaft diameters and lengths, thereby meeting actual placement requirements.

[0036] In one embodiment, a plurality of second sockets 201 are provided, and the plurality of second sockets 201 are distributed at vertical intervals to accommodate input shaft groups with different radial dimensions of the planetary gear set, thereby satisfying the requirement to accommodate input shaft groups with different planetary gear set dimensions.

[0037] Preferably, the second insertion hole 201 is formed in the support portion 22, which is detachably mounted to the seat body 21. This allows for flexibility in use when different shaft diameters need to be accommodated; simply replace the support portion 22 with a different size for the second insertion hole 201.

[0038] refer to Figures 2 to 3 The support portion 22 has at least one second mounting hole 2201, and the seat body 21 has at least one second mating hole 2101. The support portion 22 is assembled to the seat body 21 in such a way that each second mounting hole 2201 corresponds to a second mating hole 2101, and either one is first penetrated by a bolt while the other is threadedly engaged with the corresponding bolt.

[0039] Preferably, there are four of each of the second mounting holes 2201 and the second mating holes 2101, and the four second mounting holes 2201 are spaced apart in pairs. The support part 22 is assembled to the base body 21 with four bolts in such a way that the four second mounting holes 2201 correspond to the four second mating holes 2101 respectively, so as to ensure that the support part 22 and the base body 21 are firmly assembled.

[0040] In one embodiment, when there is one second insertion hole 201, there is also one second mounting hole 2201 and one second mating hole 2101. The second mounting hole 2201 is coaxial with the second insertion hole 201 and located at the center of the support part 22, so as to prevent the support part 22 from deflecting when the connection is loose, which would cause the position of the second mounting hole 2201 to change, which would be detrimental to the subsequent support of the input shaft assembly.

[0041] refer to Figures 1 to 3 The bottom of the seat body 21 forms a snap-fit ​​structure 211. The seat body 21 is assembled onto the counterweight by engaging with a pair of matching structures of a counterweight through the snap-fit ​​structure 211, so as to improve the overall stability by using the counterweight to prevent the fixture for placing the input shaft assembly from tipping over when carrying the input shaft assembly.

[0042] Preferably, the snap-fit ​​structure 211 is implemented as a slot, and the mating structure is implemented as a protrusion, the size of the slot being adapted to the size of the protrusion. The counterweight seat is assembled to the seat body 21 by means of the protrusion snapping into the slot.

[0043] Alternatively, the snap-fit ​​structure 211 is implemented as a protrusion, and the mating structure is implemented as a slot, the size of which is adapted to the size of the protrusion. The base body 21 is assembled to the counterweight base by means of the protrusion snapping into the slot.
