[0037] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of protection of the present application.

[0038] Embodiment one: please refer to Figures 1-14 The present application provides the following technical solutions: a rotor pressing ring assembly electrical performance detection device, which comprises a detection table 1 and a support seat 2 fixedly installed on the detection table 1, a longitudinal air cylinder 3 fixedly installed on the support seat 2, a pressing rod 4 connected to the output end of the longitudinal air cylinder 3, and a pneumatic sleeve 5 driven by air pressure slidably sleeved outside the pressing rod 4; a guide slide rail 6 fixedly installed on the support seat 2, a sliding seat 7 snapingly and slidably connected to the guide slide rail 6, a lifting frame 8 fixedly installed on the sliding seat 7, a transverse air cylinder 11 fixedly installed on the lifting frame 8, a moving support 12 connected to the output end of the transverse air cylinder 11, and a probe 13 fixedly installed on the moving support 12 and used for electrical performance detection in contact with a rotor; a longitudinal adjusting mechanism for adjusting the detection height of the probe 13 arranged on the support seat 2, and a transverse adjusting mechanism for adjusting the horizontal distance between the two probes 13 arranged on the support seat 2.

[0039] The longitudinal adjusting mechanism comprises a crank handle 9 rotatably installed on the support seat 2, and a threaded rod 10 coaxially connected to the crank handle 9.

[0040] The transverse adjusting mechanism comprises a driven limit block 14 fixedly installed on the moving support 12; a positioning rod 15 fixedly installed on the lifting frame 8, a limit seat 16 movably sleeved outside the positioning rod 15, and a positioning hole 17 formed in the limit seat 16 and slidably matched with the positioning rod 15; and the driven limit blocks 14 are symmetrically arranged at positions on both sides of the limit seat 16 and laterally move in contact with the side surface of the limit seat 16.

[0041] When detecting, the motor rotor is placed in the detection groove 19, and the detection position of the probe 13 is adjusted according to the diameter of the rotor and the position of the rotor installed on the motor. First, the threaded rod 10 is rotated by the handle 9, and the threaded rod 10 is threadedly connected with the lifting frame 8. Under the threaded transmission, the sliding seat 7 on both sides of the lifting frame 8 is clamped on the guide rail 6 to slide, the height of the lifting frame 8 is adjusted, and the longitudinal movement of the lifting frame 8 drives the synchronous movement of the probe 13, so that the longitudinal position of the probe 13 for electrical detection can be adjusted.

If there is a pressure line ring on the surface of the rotor, after the pressing rod 4 is controlled to press on the surface of the rotor, the pneumatic sleeve ring 5 is pushed by the air pressure to continue to move downward.
