Motor brush welding device

Abstract

The invention belongs to the field of motors, and discloses a motor brush welding device which comprises a base. One end of the base is provided with a first tool unit, and the first tool unit comprises two electric brush positioning plates, a reed supporting seat and a reed pressing rod; the two electric brush positioning plates are respectively connected with two sides of the end part of the base, electric brush grooves for accommodating electric brushes are formed in the tops of the electric brush positioning plates, threaded holes are formed in two sides of each electric brush groove, electric brush ejector rods in threaded connection are arranged in the threaded holes, and the electric brush ejector rods are used for ejecting the electric brushes accommodated in the electric brush grooves; the reed supporting seat is movably connected with the base and is positioned between the two electric brush positioning plates; a protrusion is arranged at the end of the base, a mounting hole is formed in the protrusion, one end of the reed pressing rod penetrates through the protrusion and is located above the reed supporting seat, and a gap between the reed pressing rod and the reed supporting seat is used for containing the reed. The production requirements of torque motors of different models are met, the electric brush welding production efficiency and the tool repeated utilization rate are greatly improved, and the tool cost is saved.

Description

technical field [0001] The invention belongs to the field of motors and relates to a motor brush welding device. Background technique [0002] The DC torque motor is a kind of torque motor, and it is a torque motor that uses DC as the power supply. It is a special motor with soft mechanical characteristics and wide speed range, which can output higher speed with smaller output torque. Moreover, the rotating speed and output torque can be adjusted independently, which is convenient to use and easy to operate, and has higher controllability than ordinary AC torque motors. [0003] As an important component of the DC torque motor, the brush requires good electrical conductivity, thermal conductivity and lubrication performance, and has a certain mechanical strength and the instinct of commutation sparks. The brush is responsible for conducting current between the rotating part and the stationary part. The brush reed serves as the connecting element between the lead wire and t...

AI Technical Summary

Problems solved by technology

[0004] The existing welding tools for brushes and reeds all weld the brushes of the same model and the same specification batch, which not only has high cost, but also has low production efficiency

In addition, the existing welding equipment is difficult to guarantee the dimensional accuracy, and the requirements for the welding level of the workers are relatively high
