Technical Field

[0001] This application relates to the field of testing tooling technology, and in particular to a testing tooling for long strip automotive lamp injection molded parts. Background Technology

[0002] The long strip headlight injection molding part inspection fixture is a special inspection equipment designed for the injection-molded parts of long strip headlights in automobiles. Its core function is to quickly and accurately verify key indicators such as the dimensional accuracy, appearance quality, and assembly compatibility of the injection molded parts, ensuring that they meet the technical specifications and safety standards of automobile production.

[0003] Existing equipment cannot flexibly adapt to the workpiece clamping requirements during the inspection of long strip car light injection molded parts, which can easily lead to the workpiece not being clamped or being damaged. Long strip car light injection molded parts are long and have some irregular structures. If they cannot be clamped, the workpiece will shift and shake during inspection, which can easily cause inspection deviations.

[0004] Therefore, a new approach is needed to solve this problem. Utility Model Content

At this time, the compression spring 14 will be compressed. Then, the pressure block 12 is rotated to press on the workpiece. Under the action of the spring rebound force, workpieces of different specifications are clamped. The workpiece is inspected by inserting the depth gauge into the corresponding coaxiality detection block 18. Then, the hole diameter is inspected by the hole inspection rod 22. When it is necessary to disassemble the workpiece, the hand block 13 needs to be rotated again to reset its rotation. Then, the hand block 13 is released. The compression spring 14 will reset under its rebound force and push the corresponding pressure block 12 to engage in the corresponding slot 16.
