The displacement sensor moves left and right, the extension length of the insert is measured, the test probe is in contact with the flange insert to form a test loop, and electrical performance parameters such as the insulation performance of the insert, the current and the like are measured through an electrical tester.

During manual detection, the electric performance is measured by plugging and unplugging the plug, and the extension length of the inserting sheet is measured by a special test tool. However, during manual production, an operator works for a long time, and is inevitably distracted, easy to miss tests and the like, so that complaints and complaints of customers and even OEMs (original equipment manufacturers) are caused. And the measurement takes long time, the workload of operators is large, and the efficiency is low.

Through the above analysis, the problems and defects of the prior art are as follows:

(2) The existing flange component testing device has the disadvantages of long measuring time consumption, large working load of an operator and low efficiency.

The difficulty in solving the above problems and defects is:

1. the flange excircle and the extension length of the inserting sheet depend on manual detection, no automatic detection means exists, the detection time consumption is long, the missing detection rate is high, whether the detection is qualified or not mainly depends on the judgment of an operator, the test environment and the self state of the operator have great influence on the test result, and the conditions of missing detection and judgment error are easy to occur.

2. The extension length of the inserting sheet cannot be displayed.

The significance of solving the problems and the defects is as follows: with the rapid development of modern industry, automation equipment is gradually developing towards intellectualization, flexibility, energy conservation, high precision, high quality and high safety. The high-integration automatic testing device for the comprehensive performance of the flange assembly reduces labor cost and labor intensity, reduces detection beats, improves detection efficiency and detection reliability, meets the requirement of rapid and accurate measurement of the flange assembly in the automobile industry, and improves customer satisfaction.
