Hongyi Tengda automotive sheet metal checking fixtures are high-precision special testing equipment in the automotive manufacturing industry, designed for dimensional accuracy and assembly compliance inspection of body stamping sheet metal parts and welded assemblies. The product line covers a full range of body sheet metal parts, including A-pillar/B-pillar reinforcement plates, threshold inner plates, hood/trunk/door assemblies, and composite PCF fixtures for shock towers and front wheel housings. Designed strictly in accordance with the 3-2-1 positioning principle and vehicle RPS benchmarks, it 1:1 restores the loading posture of parts, enabling fast and accurate 100% online inspection.

Adopting a high-rigidity base and contoured structure, equipped with standardized testing components such as positioning pins, clamping devices, inspection pins, and feeler gauges, the fixture can efficiently complete full-dimensional inspection of part profile, hole position, edge step difference, assembly gap, etc. A single part can be judged in 1-2 minutes, effectively monitoring mold wear and production dimensional fluctuations, and ensuring the consistency of mass production. The product is vehicle-specific with an accuracy of ±0.05~±0.1mm, balancing inspection efficiency and precision. It is widely used in stamping and welding workshops of OEMs and parts suppliers, serving as the core tool for quality control of body sheet metal parts.
