Cable bending fatigue testing device

Abstract

The present invention relates to a testing technology, and provides a cable bending fatigue testing device including a base, a fastening device, a motor and a control device. An output shaft of the motor horizontally directly faces to the fastening device, and the output shaft is fixedly provided with a movable plate which can swing in the forward direction and the reverse direction with forward rotation and reverse rotation of the output shaft. One end of a cable to be tested is fastenedly fixed on the fastening device, the other end of the cable to be tested is bent and then is fixed on the movable plate and can be bent back and forth in the forward direction and the reverse direction with the forward swing and the reverse swing of the movable plate, both sides of the movable plate are each provided with a travel switch, the travel switches are connected with the control device, and a counting unit is arranged in the control device. According to the invention, one end of the cable to be tested is fixed through the fastening device, the other end of the cable to be tested is bent and then is connected with the movable plate and is cyclically bent in the forward direction and the reverse direction under the drive of the output shaft of the motor, furthermore, counting is carried out through the control device, and thus the bending fatigue strength of the cable to be tested can be tested; with the testing device, operations are simple and reliable, the work intensity is reduced, and the work efficiency is improved.

Description

technical field [0001] The invention relates to testing technology, more specifically, to a cable bending fatigue testing device. Background technique [0002] Cables, as necessary connectors in the use of lamps, are mainly used to connect load lamps and power sources. In use, they will not only be affected by the external environment, but also human factors will affect their life. In the process of use, it is inevitable that there will be bending, stretching, friction, torsion, etc., so the bending resistance, wear resistance, torsion resistance, and stretching resistance of the cable greatly affect the use of the cable. Safety, when it does not meet the above performance requirements, safety accidents such as broken skin short circuit, open circuit, and leakage will occur, which will bring safety hazards to people's lives and property safety. Therefore, in order to obtain effective safety protection, these cables need to be bent before use. Folding fatigue test, there is ...

Problems solved by technology

In the process of use, it is inevitable that there will be bending, stretching, friction, torsion, etc., so the bending resistance, wear resistance, torsion resistance, and stretching resistance of the cable greatly affect the use of the cable. Safety, when it does not meet the above performance requirements, safety accidents such as broken skin short circuit, open circuit, and leakage will occur, which will bring safety hazards to people's lives and property safety. Therefore, in order to obtain effective safety protection, these cables need to be bent before use. Folding fatigue test, there is no fixture in the traditional test, the test process is complicated, manpower, material resources are consumed, and the cost is high
