Vehicle lights are tools for automobiles to illuminate roads during night driving, mainly including headlamps, rear lamps, turn signals, and license plate lighting lamps. They also serve as tools for sending various driving signals and providing illumination. To provide drivers with more reliable and safer usage guarantees, auto parts manufacturers must strictly control and screen the quality of vehicle lights during production. Today, we will focus on the dimensional inspection of vehicle light products.

Measurement solution

Vehicle lights are injection molded parts with tough materials that are not easily deformed, requiring measurement of coordinate errors of curved surface points. Lihe Precision's precision inspection solution for vehicle lights can meet the high-precision manufacturing requirements of auto parts manufacturers for vehicle lights. This measurement solution adopts a classic moving-bridge CMM paired with the CZ10T-S indexing automatic probe holder, easily handling the measurement of coordinate errors of curved surface points, realizing fast contact measurement, and accurately collecting dimensional data of vehicle light products.

Measurement process

1. Use a fixture or CMM-specific fixture for clamping and fixing to prevent deformation and position movement of the workpiece during measurement.

2. Import the vehicle light workpiece model into the measurement software, and establish a coordinate system using the iterative method to align the product's coordinate system with the assembly coordinate system and match the CAD model.

3. Take arbitrary points on the digital model for programming, run the program to automatically measure the position deviation of the workpiece's curved surface points. Finally, generate a graphic and text report of the measurement results.

The auto parts industry is an important part of the automobile industry. Lihe Precision has created an efficient and accurate precision measurement solution for vehicle lights to assist the high-quality development of the auto parts industry.
