AI Technical Summary

Technical Problem

Existing technology cannot simultaneously test the tightness of the seat belt bracket and the side reinforcement plates, resulting in the need for multiple repeated operations during the testing process, which is inefficient and produces inconsistent test results, posing a safety hazard.

Method used

A synchronous extension detection device was designed. Through the cooperation of components such as support frame, cylinder, guide plate and displacement sensor, the device can realize the synchronous detection of both sides of seat belt bracket and reinforcing plate. The cylinder drives the guide plate and extension pin to detect the tightness, and the displacement sensor senses the displacement to realize automated detection.

Benefits of technology

It improves testing efficiency and accuracy, reduces labor and equipment costs, meets the needs of large-scale production of automotive parts, and ensures the consistency and accuracy of test results.

Abstract

The utility model discloses a synchronous extension detection device, which relates to the technical field of safety belt support detection and comprises a support frame and a support plate mounted on the upper surface of the support frame. A first cylinder is arranged on the upper surface of the supporting plate, and the output end of the first cylinder penetrates through the supporting plate and is fixedly connected with the upper surface of a lifting plate; a spring is fixedly arranged on the lower surface of the lifting plate, and the other end of the spring is connected with a guide fixing plate; a third limiting groove is formed in one side of the guide fixing plate, and a guide plate matched with the third limiting groove is slidably arranged on the third limiting groove; according to the utility model, the second cylinder drives the guide plate to move up and down in the second limiting groove, and the extension pin synchronously extends forwards under the action of the guide shaft to carry out push detection on the tightness of the two sides of the safety belt bracket and the reinforcing plates, so that the synchronous detection on the tightness of the connection of the safety belt bracket and the reinforcing plates on the two sides is realized; the detection efficiency and precision are improved, and the requirement for large-scale production of automobile parts is met.
