Characteristics of automotive stamping parts inspection

Automobile stamping parts are a kind of metal stamping parts, which are widely used. There are usually hundreds of stamping parts in a car. When processing automotive stamping parts in a stamping plant, you often need to be more strict with yourself, because the requirements for automotive stamping parts will be higher. Today, precision mainly analyzes the characteristics of automobile stamping parts in inspection. 1. Automobile stamping parts are often complicated and irregular, and it is difficult to accurately locate, support, and clamp; 2. The stiffness of automobile stamping parts is generally weak, and it is very easy to cause errors due to deformation during the entire inspection process; 3. Except for a few small ones In addition to stamping parts, the size standards of stamping parts are generally placed in the body coordinate system for processing, except for many characteristic positions of the workpiece (such as holes, bosses, etc.), the distance between adjacent coordinate lines is indicated on the drawing. In addition, for the vast majority of contours (very random slopes), the size scale has not yet been obtained. Nowadays, the method of indicating the size with coordinate grid, which is widely used in the 1980s, has gradually been replaced by CAD data information. The CAD data information of stamping parts, weldments and even car bodies supplied by the technical department can be used as the basis for the size of manufacturing molds, welding fixtures and tooling fixtures.
