Torsional strength testing torsion testing machine

Abstract

The invention relates to a torsional strength testing torsion testing machine, which comprises a rack and an operation table, wherein the rack is provided with the operation table and a guide rail, the guide rail is provided with a test operation table, the test operation table is provided with an operation rod and an emergency stop component, an opening / closing rod is arranged beside the operation rod, positioning blocks are arranged between the test operation table and the guide rail and are positioned on the bottom portion of the test operation table, and the positioning block is made from an alloy steel material. According to the present invention, the top portion of the guide rail is provided with the baffle, such that the distance between the clamping jaw and the clamping member can be well controlled, the impact of the clamping jaw on the clamping member due to the over high force applying is prevented, the use safety of the clamping jaw and the clamping member is ensured, and the damage on the clamping jaw and the clamping member is avoided; and the hand wheel drives the screw rod to control the movement of the clamping jaw, such that the movement speed is uniform, and the torsional strength testing result of the electric cable is accurate.

Description

technical field [0001] The invention relates to a testing machine, in particular to a torsion testing machine for testing torsional strength. Background technique [0002] When testing the torsional strength of the cable, it is often necessary to use a torsion testing machine for testing. The torsion testing machine clamps the cable through the claws on both sides and then moves each other to twist the cable. It can test the resistance of the cable when it is subjected to torsion in time. How much is the torsional strength? Know the mechanical properties of the produced cables in time. However, many torsion testing machines are inaccurate when they are in use. The test console on the guide rail is easy to hit the other side when operating. The clamping parts cause the claws to be damaged, which affects the use of the torsion testing machine and reduces the use effect of the torsion testing machine. In some cases, the connection between the torsion testing machine and the gui...

The clamping parts cause the claws to be damaged, which affects the use of the torsion testing machine and reduces the use effect of the torsion testing machine. In some cases, the connection between the torsion testing machine and the guide rail is not firm, and the experimental console is directly fixed on the guide rail. The force on the guide rail is uneven, and the guide rail is damaged, which affects the actual use of the guide rail
