Description

Technical Field

[0001] The utility model relates to the technical field of automobile headlights, in particular to a fixture tooling for auxiliary detection of automobile headlights. Background Technique

[0002] In the auxiliary detection of automobile headlights, the fixture tooling plays a crucial role. Specific functions: 1) Precise positioning and fixation: The primary function of the fixture tooling is to ensure the precise positioning and fixation of the automobile headlights during the detection process. By designing a reasonable fixture structure, it can ensure that the headlights maintain a stable posture and correct position on the detection table, which is crucial for subsequent detection work. Precise positioning and fixation help reduce detection errors caused by position deviation and improve the accuracy of detection results. 2) Improve detection efficiency: On the automobile production line, time is efficiency. The fixture tooling can quickly and conveniently install the headlights onto the detection equipment, eliminating the cumbersome manual adjustment process in traditional methods. This not only reduces the complexity and time cost of manual operations but also improves the automation level of the entire detection process, thus significantly enhancing the detection efficiency.

[0003] Deficiencies have been found in the existing fixture tooling for auxiliary detection of automobile headlights during use. Firstly, it cannot reliably clamp automobile headlights with different shapes and has poor adaptability. Secondly, after clamping the automobile headlights, it cannot drive them to flip according to requirements to better meet the detection needs. Therefore, it is necessary to optimize and improve the existing structure of the automobile front combination lamp. Content of the Utility Model
