What are the design methods of small car inspection tools? In this paper, starting from the automobile structure and combining with an example, the general method of the design of the body stamping parts inspection tools is expounded.

1. The small stamping parts of the body are mainly composed of the bottom panel assembly, the clamping device group, the inspection details, the positioning pin of the main pair and the section template, etc. The main elements of the inspection are the position of the workpiece shape (including the outline of the workpiece and the shape of the surface, etc.) with holes, flanges and other features.

In the design of small vehicle inspection tools, the size reference is usually placed in the body coordinate system, and the coordinate line is drawn every 100mm in the direction of X,Y and Z.

2. Most of the body stamping parts have the characteristics of spatial surface and more local features, such as non-axisymmetric and less rigid, so it is difficult to locate, support and clamp. At present, most of the body stamping parts are inspected by CNC machine tools according to the number of models and predetermined processing procedures to automatically complete all the surface and hole positions that need to be processed at one time, small car inspection of specific materials are mostly epoxy resin.

After the design is completed, the location and size of the floor assembly shall be determined according to the vehicle inspection tools, and the section samples shall be set at the key sections to be inspected.
