Composition and characteristics of inspection
The main element of detection is the position of the shape of the workpiece (including the contour of the workpiece and the shape of the curved surface, etc.) with features such as holes and flanges. In the design of the inspection tool, the size reference is generally placed in the body coordinate system, and the coordinate lines are drawn every 100 mm in the X, Y, and Z directions. The reference block and the reference hole on the bottom plate are used to establish the coordinate system of the inspection tool.
Most of the body stamping parts have spatial curved surfaces and more local features, and have the characteristics of non-axisymmetric and poor rigidity. Therefore, positioning, support and clamping are difficult. At present, most of the inspections of body stamping parts are automatically completed by the CNC machine tool according to the numerical model and the predetermined processing program. All the surfaces and holes that need to be processed are automatically completed at one time. The specific materials are mostly epoxy resins. After the specific design is completed Then, determine the position and size of the bottom plate assembly according to the specific inspection, and set the cross-section model at the key cross-section to be inspected.
