Abstract

The invention discloses an assembly fixture for a motor brush carrier. The assembly fixture for the motor brush carrier achieves the technical effects of fine assembly and accurate locating of the brush carrier for fixing an electric brush in a motor. The assembly fixture comprises a motor end cover (1) and the electric brush carrier (2). The motor end cover (1) is provided with a receding hole (11) and an end cover bearing chamber (6). The electric brush carrier (2) is provided with an electric brush assembly hole (3). One end of an electric brush locating core shaft (4) is provided with a cylindrical step end shaft (7). The electric brush locating core shaft (4) is provided with a through hole (9). The cylindrical step end shaft (7) is arranged in the end cover bearing chamber (6). An inner check mouth end face (8) on the end cover bearing chamber (6) abuts against a cylindrical step vertical surface (5). An electric brush locating rod (10) penetrates through the receding hole (11) and the through hole (9) in sequence and then is connected with the electric brush assembly hole (3) in a penetrating mode. The assembly fixture substantially improves the assembly accuracy of the electric brush and a rotor and lowers the occurrence rate of collecting ring ablation accidents.

Description

technical field [0001] The invention relates to an assembly tool for a motor, in particular to an assembly tool for accurate positioning of a motor brush holder. Background technique [0002] The quality of the sliding contact between the brush and the slip ring of the motor will directly affect the commutation performance of the motor. During the assembly process of the motor, in the past, only attention was paid to whether the contact between the slip ring and the brush was in place, the concentricity of the central axis of the entire brush set installed with the central axis of the motor rotor, and the alignment of the brush on the axial direction of the motor. The accurate positioning of the lack of enough attention. The existing installation and positioning method of the motor brush holder is carried out manually, and then corrected by means of inspection and correction, which has the defect of low installation accuracy of the brush holder, and the installation error o...
