The invention discloses an industrial robot built-in wiring harness abrasion and accelerated abrasion test method and device. No method and no device specially aiming at the abrasion test of a built-in wiring harness of an industrial robot exist in the prior art. The device provided by the invention mainly consists of a plurality of wiring harnesses, a camera, a simulated mechanical arm, a wiringharness joint motor, a camera space position regulating device, a multi-wiring-harness bundling device, a swinging motor, an installing seat, a holding hoop, a swinging arm, a simulation board, a simulation board swinging rotation device, a simulation board moving platform, an industrial personnel computer, a motor movement controller, a swinging motor driver, a step motor driver and an image collection card. The plane abrasion test or joint constraint abrasion test can be selected; the swinging amplitude and the swinging period of the swinging motor are controlled according to the wiring harness abrasion mode or the wiring harness accelerated abrasion mode; next, an imaging recognition technology is used for recognizing the wiring harness abrasion region due to simulation; the wiring harness abrasion and accelerated abrasion detection intelligence is realized; and the image processing process is simple and efficient.
