Problems solved by technology

Although the utility model reduces the difficulty of processing and improves the production efficiency, when the commutator is arranged, because the position of the positioning block is fixed, misalignment may occur between the positioning blocks on two adjacent commutating segments As a result, misalignment occurs between two adjacent commutator segments, which is not conducive to realizing high-efficiency arrangement of commutator segments

Abstract

The invention relates to the technical field of commutators, and particularly discloses a pure copper mica-free commutator and a production process thereof. The pure copper mica-free commutator comprises a commutator main body. The commutator main body comprises commutator segments, and each commutator segment comprises a commutator segment body and a root part. Two first positioning blocks are arranged on each of the two end surfaces of the commutator segment body along the short axis direction. The two first positioning blocks are arranged at an interval along the length direction of the commutator segment body. A second positioning block is arranged between the two first positioning blocks. The first positioning blocks and the second positioning blocks on the same end face of the commutator segment body are arranged in a staggered mode in the short axis direction of the commutator segment body, the first positioning blocks on the two end faces of the commutator segment body are arranged in a staggered mode in the short axis direction of the commutator segment body, and correspondingly, the second positioning blocks on the two end faces of the commutator segment body are arrangedin a staggered mode. According to the commutator, the segment arrangement efficiency in the commutator production process is improved, and interference on the subsequent production process due to dislocation between two adjacent commutator segments is avoided.

Description

technical field [0001] The invention relates to the technical field of commutators, in particular to a pure copper mica-free commutator and a production process thereof. Background technique [0002] The commutator is a very important part of a DC motor. At present, during the processing of the commutator, mica sheets and commutator segments are alternately arranged to prevent short circuits caused by contact between adjacent commutator segments. However, it is very troublesome to use mica slices and commutation slices to arrange the operation, and the accuracy of mica slice arrangement is high, and the position deviation of mica slices will cause the commutator to be unable to process normally, which will increase the size of the commutator. The difficulty of processing increases labor costs. [0003] The patent document with the application number CN201320376052.X discloses a mica-free commutator structure, including a base and a commutator segment, the commutator segmen...
