一种刷压检测装置
By designing a brush pressure detection device, a servo motor drives a unidirectional lead screw and a pressure sensor to detect the contact pressure between the brush bristles and the slip ring in real time. This solves the problem of not being able to accurately obtain the brush pressure value in existing devices, and realizes accurate performance analysis and stable detection of the bus ring.

AI Technical Summary
Existing devices cannot accurately determine the real-time brush pressure between the brush bristles and the slip ring, which causes many inconveniences in the development, debugging, use and maintenance of the bus ring, making it difficult to accurately obtain the brush pressure value under different adjustment states, thus affecting performance analysis.
A brush pressure detection device was designed, including a detection platform, a fixing mechanism, and a clamping mechanism. A servo motor drives a unidirectional lead screw to move a plate. A pressure sensor detects the contact pressure between the brush bristles and the slip ring in real time, and the data is displayed by a PLC controller. The fixing mechanism and clamping mechanism together ensure the stable fixation of the brush holder and the slip ring.
It enables precise detection of the contact pressure between the brush bristles and the slip ring, ensuring the accuracy and stability of the detection results. It solves the problem of not being able to accurately obtain the brush pressure value in existing devices, and improves the efficiency of the development, debugging and maintenance of the bus ring.
