Description

Technical Field

[0001] The invention belongs to a tension testing machine, in particular to an automatic chain safety tension testing machine. Background Art

[0002] The chain tension test is relatively complicated. Since the chain is supplied as an integral part, the chain supply will stop and stagnate during the tension test. Therefore, it is easy to have insufficient tension. As a result, the chain will accumulate somewhere, forming knots or entanglements, which will affect the overall operation. Therefore, when solving such problems, the chain is usually tension tested alone, which makes the tension test more time-consuming and the overall efficiency is low.

[0003] For example, an automatic wire harness terminal tension testing machine disclosed in application number CN202011407482.4 includes a frame, a terminal chuck, a wire harness clamping mechanism, and a tension testing mechanism. The terminal chuck is arranged on one side of the top of the frame, and a plurality of slots are provided on the terminal chuck. The wire harness clamping mechanism includes a pressure plate and a pressure roller arranged on the other side of the top of the frame. The frame is provided with a transverse movement mechanism for driving the pressure plate to move. The pressure roller is arranged on the upper side of the pressure plate near the front end of the terminal chuck. A support block for supporting the pressure roller is provided on the front side of the pressure plate. There is no contact between the pressure roller and the pressure plate. An eccentric shaft is provided on the side of the pressure roller near the terminal chuck, and both ends of the eccentric shaft are movably connected to the support block. A toggle handle for rotating the pressure shaft is provided on the pressure roller. An arched boss is provided on the rear side of the pressure plate. A torsion spring is provided on the eccentric shaft, one end of the torsion spring is connected to the support block, and the other end of the torsion spring is connected to the pressure roller. The cable is conveniently fixed and has a good fixing effect, thereby improving the accuracy and efficiency of the test. Summary of the invention
