Description

Technical Field

[0001] The utility model relates to the technical field of automobile parts detection devices, and more specifically to a detection device used for automobile parts production. Background Art

[0002] As the foundation of the automobile industry, auto parts are a necessary factor to support the sustainable and healthy development of the automobile industry. In particular, the current independent development and innovation in the automobile industry, which is in full swing, requires a strong parts system to support it. The independent brand and technological innovation of the whole vehicle need parts as a foundation, and the independent innovation of parts has a strong driving force for the development of the whole vehicle industry. They influence and interact with each other. Without the independent brand of the whole vehicle, the R&D and innovation capabilities of the strong parts system will be difficult to burst out. Without the support of a strong parts system, it will be difficult for the independent brand to grow bigger and stronger.

[0003] After the stamping parts in automobile parts are produced, they need to be tested for flatness. The traditional testing method is to manually place the product flat on the testing platform and use a feeler gauge or a height gauge for testing. There are many unstable factors in the testing, and the testing time is also long. The testing efficiency is low and cannot meet the modern production scale. The existing patent is a testing device for automobile parts production, and the patent authorization number is CN 212300310 U. The testing device for automobile parts production can perform multi-point flatness detection on the top of the stamping part.

[0004] However, the patent authorization number CN 212300310 U adjusts the position of the flatness detector by moving the displacement active drive gear left and right and the U-shaped transmission part forward and backward on the limit baffle, thereby achieving the technical effect of multi-point flatness detection of different parts of the stamping part. Since the device detects flatness, it cannot detect wheel hub accessories. In order to be able to detect automotive accessories with curved surface structures, we propose a detection device for automotive accessories production to solve the above-mentioned problems.
