Description

Technical Field

[0002] The electromagnetic brake is a connector that transmits the torque of the active side to the passive side. It can be freely connected, disconnected or braked as needed. It has the advantages of compact structure, simple operation, sensitive response, long life, reliable use, and easy remote control. In order to ensure the normal use of the electromagnetic brake, it is necessary to test the dynamic torque.

[0003] The Chinese patent document with the announcement number CN210487131U discloses a rapid test device for electromagnetic brake torque, which drives the first clamp block and the second clamp block to move by sliding a slider in a slide groove. The electromagnetic brake is clamped by the first clamp block and the second clamp block, and then the fixing bolt is passed through the inside of the fixing hole and tightened to fix the first clamp block and the second clamp block, and then the strap is pulled out through the perforation, and the strap drives the column to rotate when it is pulled out, and the coil spring deforms with the rotation of the column. After the strap is pulled out, the electromagnetic brake is tied with the strap, and after the strap is tied with the electromagnetic brake, the clamp hole on its surface is used to clamp it on the hook, so as to fix the strap and fix the electromagnetic brake on the mounting table to prevent the electromagnetic brake from shaking during the test and affecting the test.

[0004] However, there is a shortcoming in the use of the original equipment. In the process of fixing the electromagnetic brake through the fixing component, due to the contact between the electromagnetic brake and the direct fixing component, the electromagnetic brake itself is prone to vibrate when outputting power, causing a slight collision between the electromagnetic brake and the fixing component, resulting in abnormal noise.
