Moment-testing tool test bench

The invention discloses a moment-testing tool test bench, and the test bench comprises a bottom plate, a positioning shaft, a pressure plate, a bearing, a fixed sleeve, a transmission block, a first locking screw, a transmission shaft, a second locking screw, and a transmission box. The test bench is characterized in that the positioning shaft is disposed in the transmission shaft, and is connected with the second locking screw; the fixed sleeve is disposed in the transmission box; the transmission shaft is disposed in the bearing in the fixed sleeve; a moment-testing bench is changed into a gear transmission structure, so as to test a loading moment of an electromagnetic brake part, thereby greatly reducing the labor intensity, and greatly improving the production efficiency. The gear transmission of the moment-testing bench has certain self-locking performance, so the tested moment deviation is very large. Through repeated testing, a device for detecting the loading moment of an electromagnetic brake in a rear axle mechanism reduces the labor intensity by 90%, improves the production efficiency by 20 times, and achieves 100% data authenticity.
