[0016] The utility model will be further explained below in combination with the drawings and embodiments.

[0017] In the description of the utility model, it should be explained that unless there is explicit provision and limitation, the terms "connected", "connected" should be understood broadly, for example, it can be fixedly connected, or integrally connected, it can be mechanically connected, or electrically connected, it can be directly connected, or indirectly connected through intermediate medium.

[0018] Figure 1 And Figure 2 The clamping tool of the cycloid motor sleeve part shown in the figure comprises a bottom plate 1, two shaft holes are formed in the upper surface of the bottom plate 1, a positioning mandrel 2 for sleeving the cycloid motor sleeve part is fixed on the upper surface of the bottom plate 1 at the shaft hole position through bolts, and a half-lack pressing plate 3 for fixing the cycloid motor sleeve part is assembled on the upper end of the positioning mandrel 2 through bolts.

[0019] In order to match the lateral assembly limit, lateral assembly limit grooves 4 are formed on both sides of the bottom plate 1.

[0020] The lateral assembly limit groove 4 can be fixedly assembled with the bottom plate 1 through bolts.

[0021] In order to match the assembly and fixation, the positioning mandrel 2 comprises a bottom mounting shaft 21 inserted into the shaft hole, an upper assembly shaft 22 fixedly arranged on the upper end of the bottom mounting shaft 21 in the axial direction and a fixed flange plate 23 fixedly arranged on the connecting end of the bottom mounting shaft 21 and the upper assembly shaft 22.
