DC torque motor brush welding jig and welding processing method

Abstract

The invention discloses a brush welding fixture for a DC torque motor and a welding processing method, which solves the problems of high requirements on operators for brush welding, large batch differences in manual welding, and low qualification rate. A brush positioning plate and a reed positioning plate are installed on the front surface of the base body of the brush welding fixture; the top of the base body is provided with a forward first protrusion; In the pit where the brushes to be welded are placed, the inclination angle of the bottom surface of the pit is the same as the inclination angle of the top surface of the brush positioning plate; there is a threaded hole between the left end face of the brush positioning plate and the pit; After the rod is matched with the threaded hole, one end is located outside the left end face of the brush positioning plate, and the other end extends into the pit; the thickness of the reed positioning plate is adapted to the width of the reed to be welded; the top of the reed positioning plate is provided with a A second protrusion adapted to the bending angle of the welding reed; the reed pressing rod vertically passes through the first protrusion and then presses the to-be-welded reed.

Description

technical field [0001] The invention belongs to the field of motor assembly and manufacture, and in particular relates to a DC torque motor brush welding fixture and a welding processing method. Background technique [0002] DC torque motor is characterized by large stall torque, low no-load speed, can directly drive load without any deceleration device, and has strong overload capacity. It can generate enough torque without damage when it is locked for a long time. It is widely used in high-precision transmission systems such as the drive of various radar antennas and photoelectric tracking. [0003] As an important component of the DC torque motor, the brush is responsible for conducting current between the rotating part and the stationary part. The brush reed is used as the connection element between the lead wire and the brush, and also provides a certain pressure for the brush. Make sure that the brushes and rotor are in tight contact. The welding quality of the brus...

Problems solved by technology

[0005] The present invention provides a brush welding jig and welding processing method for DC torque motors, which solves the problem of low production efficiency due to the poor universality of the welding tooling used in conventional brush welding, and unreliable welding quality caused by the use of non-metallic materials in the welding tooling. Issues such as large batch differences
