Multi-wire-harness space torsion/bending frictional wear test method and device

Abstract

The invention discloses a multi-wire-harness space torsion / bending frictional wear test method and device. As a carrier of power transmission and control capability of the robot, the cable is generally very important as the heart of a person for the industrial robot. However, in the production process, people can find that the industrial robot is prone to bending and twisting of the multi-wire-harness cable in the high-speed movement process, and the service life of the cable can be severely tested. After the wire harnesses are tested for multiple times, the wear condition of the cable in the high-speed bending and twisting state can be obtained, the number of times of bending and twisting and the resistance and temperature of the wire harnesses before and after bending and twisting are comprehensively analyzed, and therefore the wear performance of the multi-wire-harness cable is evaluated, and guiding significance is achieved for formulating the maintenance and replacement period of the high-speed moving cable. According to the invention, the wear state of the cable in different severe environments can be measured, the practicability and applicability of the device are improved, and stable operation of the device is facilitated.

Description

Technical field [0001] The present invention belongs to the field of robotics reliability of the detection harness wear, particularly, to a robotic wire harness torsion / bending frictional wear test method. Background technique [0002] Due to rising labor costs, as well as development of new technologies and new materials, a large number of industrial robots in our production occupations. The cable carrier as robot transfer power and control capabilities for industrial robots for itself, as a man's heart is generally very important. But in the production process, we can find a high-speed industrial robots in the course of the campaign and more prone to bending and twisting of cable harnesses, this will bring severe test cable life, and therefore a need for a reliable test method for high-speed movement wear performance cables are tested to ensure that the cable can meet the demand. [0003] Currently on the robot harness wear and much of its protective sleeve case detection tes...

Problems solved by technology

However, the system does not take into account the wear of the cable surface and cannot detect the wear of the protective sleeve

Patent No. CN206223578 discloses a cable torsion fatigue testing device, which is mainly composed of a fixing part, a swinging part and a driving mechanism. The test method is that the cable is driven by the swinging part to swing back and forth, and the counter records The number of swings, which can effectively simulate the effect of twisting of the cable, however, this method cannot detect the wear of the cable in the bending contact between the cable and the cable

The patent No. CN201922388686.7 discloses a cable winding torsion test device, which is composed of a shaft frame and a motor. During the test, the stepping motor is directly controlled to drive the cable to twist, and at the same time, it is equipped with a proximity sensor to detect and count the cable. number of torsional turns, but cannot detect wear from cable-to-cable flex contact

None of the above methods has made a summary and overall evaluation and detection of the surface wear degree of the bending and torsion cable, and cannot completely complete the target of the reliability detection of the cable torsion / bending friction and wear performance
