In order to ensure the safety and reliability of coal mine motors, they need to be regularly inspected and maintained. During the motor test bench inspection process, the motor needs to be fixed on the test bench for various tests. The existing clamping mechanism has unstable clamping force and is prone to shaking, which causes the clamping device to loosen and the motor cannot be accurately positioned, affecting the accuracy of its test results.
[0003] Therefore, by rotating the screw, the clamping plate clamps the motor and is squeezed, the extrusion block slides in the extrusion groove, the extrusion block drives the tilting block to move, and the tilting block slides in the tilting groove, so that the support rod moves downward along the inclined surface of the tilting block, and the base of the motor is squeezed and fixed. The motor is accurately positioned, which greatly improves the stability of the motor. By utilizing the shaking generated during motor testing, the motor shaking causes the extrusion block to move slightly, and the tilting block causes the support rod to continuously apply supporting force to the motor base up and down, thereby keeping the motor stable and preventing the fixing device from loosening due to long-term shaking of the motor.
[0004] In view of the shortcomings of existing technologies, further improvements are needed. Utility Model Content
