[0020] As an embodiment of the utility model, the self-centering clamping assembly includes a slide 5 and a clamping plate 6. Two parallel slide grooves 4 are provided on the slide 3. There are two slides 5 that slide in the two slide grooves 4. There are two clamping plates 6 that are detachably connected to the two slides 5. V-mouths 6a are provided in the two clamping plates 6, and an extension platform 6b is provided on the side below the V-mouth 6a. The two clamping plates 6 are installed in opposite directions. A driving assembly for driving the two slides 5 to approach or move away from each other is provided on the slide 3. When the two clamping plates 6 are separated, the extension platform 6b can be used to place the gear shaft. When the two clamping plates 6 are close to each other, the gear shaft can be clamped through the V-mouth 6a. At the same time, when clamped at different diameter positions of the stepped gear shaft, the axial center height of the gear shaft can also be vertically aligned with the center of the height direction of the V-mouth 6a. The self-centering clamping assembly on the two slides 3 can ensure that the heights of the two ends of the gear shaft axis are consistent.

[0021] As an embodiment of the utility model, the driving assembly includes a bidirectional threaded rod 7, which is rotatably arranged on a slide 3 between two slides 5. One side of the two slides 5 is fixedly provided with a threaded cylinder 9 screwed on the bidirectional threaded rod 7. A motor 8 is fixedly arranged on the slide 3. One end of the bidirectional threaded rod 7 is connected to the driving end of the motor 8. The motor 8 adopts a torque motor. By starting the motor 8, the bidirectional threaded rod 7 can be driven to rotate, thereby driving the two slides 5 and the splint 6 to move closer to or away from each other through the threaded cylinder 9.
