Pipe checking fixtures are high-precision special testing tools for the production of automotive pipeline components, designed for dimensional accuracy, spatial routing, and assembly compliance inspection of various automotive pipelines such as brake pipes, oil pipes, air conditioning pipes, and wire harness pipes. Strictly following the vehicle RPS benchmark and 3-2-1 positioning principle, the fixtures 1:1 restore the actual loading posture of pipelines, accurately simulate the vehicle installation conditions, and enable fast and efficient 100% online inspection.

Adopting a high-rigidity testing platform and contoured positioning structure, equipped with standardized components such as special positioning pins, clamping mechanisms, go/no-go gauges, and profile inspection blocks, the fixtures can efficiently complete full-dimensional inspection of pipe diameter, hole position, spatial line, bending angle, and assembly gap. A single part can be inspected in 1-2 minutes, effectively monitoring mold wear and production dimensional fluctuations, and ensuring the consistency of mass production. Vehicle-specific with a manufacturing accuracy of ±0.05~±0.1mm, the fixtures adapt to the inspection requirements of complex spatial routing of pipelines. Widely used in the production quality inspection links of OEMs and pipeline suppliers, they are core testing equipment to ensure the assembly accuracy, driving safety and overall vehicle reliability of the automotive pipeline system.
