Description

Technical Field

[0001] This utility model relates to the field of torsion testing machine technology, specifically to an insulating sleeve torsion testing machine. Background Technology

[0002] After the insulating sleeve is manufactured, it needs to undergo a torsion test to determine its ability to withstand plastic deformation under unidirectional or bidirectional torsion. The test can reveal surface defects in the insulating sleeve and is mainly suitable for use in the mechanics laboratories of relevant research departments, universities, and industrial and mining enterprises to determine the torsional performance of the insulating sleeve. For example, as shown in a torsion testing machine with Chinese Patent Publication No. CN214894583U, the lead screw is rotatably mounted at both ends of the drive frame. The second motor is fixed to the outside of the drive frame, and its main shaft is connected to the lead screw. The movable frame can move on the lead screw. The first motor is fixed to the movable frame. The main shafts of the chuck and the first encoder are fixed at both ends of the main shaft of the first motor. The first encoder is fixed to the first motor. The central controller is electrically connected to the first motor, the second motor, and the first encoder.

[0003] However, when using a torsion testing machine to perform a torsion test on the insulating bushing, the lack of a protective device for the insulating bushing on the chuck means that the insulating bushing may break due to torsion during the torsion test. The broken insulating bushing may then fly out during the high-speed operation of the motor, causing injury to the operator. Utility Model Content
