[0002] The commutator, also known as the "rectifier", is an important component on the armature of DC motors and AC commutator motors. It is composed of many copper sheets separated by mica sheets and is cylindrical or disc-shaped. Each copper sheet is connected to several armature winding elements. During the commutator production process, the dielectric strength test between the commutator segments is related to the quality of the commutator.

[0003] The existing commutator inter-segment withstand voltage detection device cannot meet the detection requirements of commutators of different sizes, cannot form an assembly line type detection operation line, and has low detection efficiency.

[0004] A search revealed a Chinese patent document that discloses an automatic withstand voltage test device for micromotor commutator segments [Application Number: 202022681445.4; Publication Number: CN213302421U]. This withstand voltage test device includes a test platform equipped with a material lifting mechanism. An automatic withstand voltage test unit is located above the test platform. The lifting rod of the material lifting mechanism passes through a clearance hole in the discharge station of an external horizontal conveyor, lifting the commutator to be tested from the discharge station into the automatic withstand voltage test unit for automatic testing.

[0005] Although the voltage resistance test device disclosed in this patent is capable of performing automated testing, it can only test a single commutator, cannot meet the testing requirements of commutators of different sizes, cannot perform assembly-line testing, and has low testing efficiency.

[0006] Based on this, we proposed an automatic test device for the withstand voltage between commutator segments. This device can quickly and conveniently load the commutator, meet the centering clamping requirements of commutators of different sizes, improve work efficiency and quality, meet the detection requirements of commutators of different sizes, improve detection efficiency and the reliability of detection results, and can form a pipeline-type detection operation line, thereby improving detection efficiency.
