Test bench for testing vibration of automotive dimming motor units

Abstract

The invention provides a test bed for detecting vibration of an automobile dimming motor device. The test bed comprises a base table and a vibration testing mechanism; an installation table is fixedlyinstalled on the plane of the top at the left end of the base table; and transverse guide rails are arranged at the front end edge and the rear end edge of the plane of the top on the portion, on theright side of the installation table, of the base table respectively. According to the test bed for detecting vibration of the automobile dimming motor device, because two electric air cylinders which are symmetric left and right are vertically and inversely installed on a top plate of a lifting mechanism, the tail ends of the piston ends of the two electric air cylinders are fixedly connected with L-shaped hanging plates, and guide rods A are vertically inserted into the front side and the rear side of each electric air cylinder respectively. The plane of the right end of a connecting plateis rotationally connected with a load wheel disc which is rotationally connected with a dimming motor on the left side through a coupler. The vibrating state of the dimming motor in use can be simulated, so that data which is more consistent with the actual situation is obtained.

Description

technical field [0001] The invention relates to the technical field of motor vibration testing, and more specifically relates to a test bench for detecting the vibration of an automobile dimming motor device. Background technique [0002] Servo motors, as the driving components of most high-end equipment, play an irreplaceable role in modern industries such as CNC machine tools, robots, electric vehicles, construction machinery, and precision instruments. Their performance and reliability have a huge impact on the quality of equipment systems. In particular, the dimming motor used in automobiles needs to be subjected to a vibration test before use in order to check the service life, such as a servo motor vibration shock test device in the patent application CN201720437048.8, including a support base and a first mounting plate. The support base is used for detachable installation on the vibration test bench or impact test bench. The first mounting plate is fixedly arranged o...

AI Technical Summary

Problems solved by technology

[0005] In summary, the present invention provides a test bench for detecting the vibration of an automotive dimming motor device. Through structural and functional improvements, the traditional motor test bench is mostly fixed on a fixture with no load. In the test, when the motor rotates without load, there is a deviation between the obtained data and the data obtained under load, and the difference in the fixing method will also affect the vibration test of the motor. In addition, the motor is generally heavy, and it is inconvenient to fix it during the test.
