Multi-head cable scratch-resistant test device

Abstract

The invention discloses a multi-head cable scratch-resistant test device which comprises a scratch-resistant test machine body, an electrical cabinet is arranged on one side of the scratch-resistant test machine body, a servo driver, a differential rotating collector encoder, a PLC and a relay are arranged in the electrical cabinet, the servo driver is electrically connected with a servo motor, and the PLC is electrically connected with the relay. By programming the PLC, counting can be automatically stopped when any scratch-resistant test head scraping needle is in contact with a sample conductor, alarm information is displayed on an operation screen of a human-computer interface, and normal operation counting of other test heads is not affected; meanwhile, by programming the PLC, when part of the test heads are in normal tests, other test heads without test samples can be used for testing midway, and normal counting of the running test heads is not affected. The device is convenient to operate, simple and easy to understand and long in service life, the test period is greatly shortened, and the working efficiency is greatly improved.

Description

technical field [0001] The invention relates to a multi-head cable scratch resistance test device, which belongs to the technical field of wire and cable testing. Background technique [0002] The traditional PI / PTFE composite insulated wires and cables for aerospace do not have the performance index requirements for scratch resistance, but with the rapid development of my country's aerospace industry, in order to deal with various harsh aerospace environments, such as vibration, shock It will cause the cable to be scratched, and the scratch resistance performance of the new generation of PI / PTFE smooth composite insulated wire and cable for aerospace is put forward. Whether the insulation or sheath layer of the wire and cable is scratch-resistant is also one of the methods for judging whether the wire and cable can be used for a long time. [0003] Article 10.13 of the national standard GB / T 33343-2016 "Test Methods for Aviation Insulated Wires" requires: Sample test 10 po...

AI Technical Summary

Problems solved by technology

Taking a wire with a wire gauge number of 20 as an example, the average number of cycles during scratching and conducting at room temperature should not be less than 5,000 times, that is, it takes at least 90 minutes to make a test point, while the existing reciprocating scratching test The instrument can only measure one point at the same time, and it takes at least 900 minutes to complete 10 test points. The test cycle is long and the efficiency is low.
