AI Technical Summary

Technical Problem

Existing technologies have low efficiency in tailgate alignment detection and large measurement errors, making it difficult to meet the requirements for high precision and high efficiency detection.

Method used

Design a centering inspection fixture for tailgates, including a first plate, a second plate, a detection unit, and a measuring component. The second plate slides in the left-right direction, the detection unit moves with the tailgate offset, and the measuring component directly reads the sliding distance. Combined with an adjustable detection pin and slide rail structure, the accuracy and flexibility of the inspection are ensured.

Benefits of technology

It improves the efficiency and accuracy of tailgate inspection, reduces cumbersome adjustment steps and measurement errors, adapts to the inspection needs of tailgates of different specifications, and reduces the complexity of equipment replacement and operation.

Abstract

The application relates to the technical field of tooling, and discloses a centering detection tooling and a centering detection assembly for a tail door. The centering detection tooling comprises a first plate part, a second plate part, a detection part and a measuring assembly. The second plate part is slidingly arranged on the first plate part along the left-right direction. The detection part is arranged on the second plate part and is suitable for driving the second plate part to move along the first direction when the tail door is offset. The measuring assembly is arranged on the first plate part, and the measuring assembly is suitable for measuring the sliding distance of the second plate part along the left-right direction. The centering detection tooling improves the detection efficiency.
