Vehicle body inner cavity electrophoretic coating detection fixture

Abstract

The invention provides a vehicle body inner cavity electrophoretic coating detection fixture comprising a fixture body, a steel band fixing device, an arc-shaped steel band, a steel band guide device, a guide device fixing ring, a guide shaft, a guide rod, a lifting lug fixing rod, a lifting lug, a limiting rod, a connecting rod, a U-shaped fixed rod and an operating handle. By adopting the vehicle body inner cavity electrophoretic coating detection fixture provided by the invention, the thickness of an electrophoresis membrane on the sheet metal surface of the inner part of a vehicle body cavity can be accurately reflected, the electrophoretic performance of a vehicle body structure can also be analyzed and judged according to detection results, the modes of verifying the vehicle body structure by virtue of disassembly ways can be avoided or reduced, the development cost of novel products can be effectively reduced, the development cycles of the novel products can be shortened, and the electrophoresis quality of mass-produced vehicles can be improved.

Description

Technical field [0001] The invention relates to a vehicle body detection tool, in particular to a vehicle body inner cavity electrophoretic coating detection tool. Background technique [0002] The quality of the electrophoretic coating of the car body largely depends on the structure of the car body, especially the electrophoresis quality of the inner cavity structure composed of multi-layer sheet metal of the car body will directly affect the corrosion resistance of the vehicle. At present, due to the high cost of electrophoresis verification software (such as VPS, etc.) for vehicle body structure data analysis, it cannot be popularized. Therefore, in the design verification stage or mass production process of the new product development process, verification can only be carried out by dismantling the actual vehicle. The actual situation of the optimization of the body structure or process, the cost is relatively high, and the cycle is relatively long. Summary of the invention...
