Problems solved by technology

[0003] The technical problem to be solved by the present invention is to provide a kind of pressure sensor and pressure tracking system to collect the carbon brushes of motor brush holders in view of the current lack of dynamic testing of the elastic force test of the motor brush holder carbon brushes in the production process of automobile DC motors. The pressure signal is controlled by the PLC (Programmable Logic Controller) operation program, and the dynamic whole process elasticity test is carried out on the brush holder workpiece, so as to realize the 100% online detection of the motor brush holder carbon brush elasticity of the motor brush holder carbon brush workpiece Dynamic testing device and testing method

Abstract

The invention provides a device for testing the elasticity of the carbon brush of a motor brush rocker dynamically and a testing method thereof. The device for testing the elasticity of the carbon brush of a motor brush rocker dynamically consists of a bottom plate, a stander, a vertical cylinder, left and right linear guide rails, front and back linear guide rails, a positioning and fixing pressure gripper, a positioning tooling, left and right linear bearings, front and back linear bearings, a damping curb pin, a pressure sensor, a screw mandrel, a servo motor, a shaft coupling, a displacement sensor and a programmable network digital monitor. The test device can test the change of the elasticity curvilinear of a tested work-piece.

Description

technical field [0001] The invention relates to a vehicle accessory or a vehicle part, in particular to a dynamic test device and a test method for the carbon brush elastic force of a motor brush holder of an automobile DC motor. Background technique [0002] Test the elasticity of the carbon brush in the motor, for example, test the elasticity of the carbon brush of the vehicle ABS (full name Anit-lock Brake System) motor, window motor, wiper motor, etc., mainly to detect the carbon in the motor The elastic state of the brush after installation is to ensure the stability of the output current of the automobile DC motor during operation, reduce noise and ensure the life of the motor. Existing tests for the elastic force of carbon brushes in motors are generally performed in the laboratory or measuring room for static detection of the elastic force of a single tested workpiece. Since it is only a static detection of the elastic force of a single tested workpiece, it cannot be...
