Embodiment Construction

[0017] The technical solution will be described in further detail below.

[0018] In the method described in the technical solution, by drawing the planar structure to be detected on a transparent film at a ratio of 1:1, and then covering the transparent film on the surface structure to be detected, it is judged whether the detected structure meets the design requirements. When completing this method, the following steps are generally adopted. Step 1, draw the design pattern on the transparent film at a ratio of 1:1; Step 2, measure whether the geometric elements of the pattern drawn on the film meet the design requirements; The required transparent film pattern is covered on the surface of the object to be inspected for comparison, and it is judged whether the geometric elements of the object to be inspected meet the design requirements. In this implementation step, before testing the surface structure to be tested, it is first checked whether the geometric elements of the pa...

Abstract

The invention relates to a method for testing structural geometrical elements, more particularly to a checking method for a location degree and a geometric dimension of a surface complex structure. The method comprises: a to-be-checked plane structure is drawn on a transparent film at a ratio of 1: 1; the transparent film covers a to-be-checked surface; and whether the checked structure meets a design requirement is determined. According to the invention, the design pattern is drawn on the transparent film and the transparent film with the drawn pattern as a checking standard sample piece covers the to-be-checked surface directly to check geometrical elements of the surface structure. Therefore, the operation becomes simple and convenient; and a checking result can be obtained rapidly and visually.

Description

technical field [0001] The invention relates to a method for inspecting structural geometric elements, in particular to a method for inspecting the position and geometric dimensions of complex surface structures. Background technique [0002] In the inspection of geometric elements of product structure, some products with complex surface structures are often involved. Some products have holes and grooves of various sizes on the surface. This type of product involves many geometric dimensions and hole position dimensions, and the accuracy requirements are not high. . like figure 1 , figure 2 As shown, a large number of printed boards in electronic products involve the machining of hundreds or even thousands of plastic molds, servo drive board cold plates, DIO board heat sinks and other parts. The parts are complex in shape and involve geometric dimensions. The position between the holes and other complex parts of multiple sizes, and some rubber molded printed parts are pr...
