AI Technical Summary
In the existing technology, the tire belt layer separation force testing device has problems such as unstable clamping and unintuitive test results, which leads to test errors.
A clamping device was designed, which includes an anti-slip clamping surface and a self-locking mechanism. The clamping is stable through the cooperation of a screw and a nut, and the tensile force value is displayed by a helical tension spring and a gear and rack transmission system to ensure that the sample does not slip during the test. The device is easy to operate.
It achieves stable clamping, simple operation, improved testing accuracy and intuitive results, and reduced testing errors.
