A synchronous extension detection device

Abstract

This utility model discloses a synchronous extension detection device, relating to the field of seat belt bracket detection technology. It includes a support frame and a support plate mounted on the upper surface of the support frame. A first cylinder is provided on the upper surface of the support plate, with its output end penetrating the support plate and fixedly connected to the upper surface of a lifting plate. A spring is also fixedly provided on the lower surface of the lifting plate, with the other end of the spring connected to a guide plate. A third limiting groove is provided on one side of the guide plate, and a matching guide plate is slidably mounted on the third limiting groove. This utility model uses a second cylinder to drive the guide plate to move up and down within the second limiting groove. The extension pin, under the action of the guide shaft, extends forward synchronously to perform a push detection on the tightness of the seat belt bracket and the two sides of the reinforcing plate. This achieves synchronous detection of the tightness of the connection between the seat belt bracket and the two reinforcing plates, improving detection efficiency and accuracy, and meeting the needs of large-scale production of automotive parts.
