Description

Technical Field

[0001] This utility model relates to the field of automotive lighting manufacturing technology, specifically a measuring device for adjusting automotive headlight screws. Background Technology

[0002] In the existing technology, some vehicle headlights have three adjusting screws in different positions on their housings. The different heights of these three adjusting screws will affect the error of the headlight light source after it is installed on the vehicle. Therefore, the height of these three adjusting screws needs to be adjusted during the production process on the assembly line to ensure the adjustment accuracy.

[0003] Traditional adjustments rely heavily on manual adjustment of three adjusting bolts. However, manual adjustment alone cannot guarantee accuracy and fails to meet adjustment requirements. While some existing technologies use measuring devices for assistance, they suffer from the following drawbacks: 1. Insufficient calibration accuracy: The measuring gauges and headlight support brackets of traditional devices are statically coupled, unable to dynamically adapt to vehicle position deviations on the assembly line, leading to errors between measurement results and the actual vehicle installation state; 2. Low adjustment efficiency: Relying on repeated manual adjustments of the gauges and fixtures is time-consuming and cannot meet production line cycle time requirements; 3. Lack of synchronous calibration function: The height and angle adjustments of the headlight support brackets operate independently of the measuring system, easily leading to accumulated errors affecting the final adjustment accuracy.
