Problems solved by technology

[0003] At present, the evaluation method of high point height of stamping cover parts is relatively rough. Some are measured by spiral micrometer. This method has poor measurement accuracy and high requirements for high point position. The size of the area and the feel of the hand judge the height of the high point, which cannot be measured accurately and quantitatively

Embodiment Construction

[0035] The embodiment of the present application provides a detection method, device and testing machine for high-point defects on the surface of stamping parts. The detection method can more accurately measure the height of high-point defects of stamping parts by scanning the contour curve of the stamping parts.

[0036] The technical solution of the embodiment of the present application is to solve the above-mentioned technical problems, and the general idea is as follows:

[0037] A method for detecting high-point defects on the surface of a stamping part, comprising: adjusting a stamping part sample to a target state, and the target state is a horizontally placed state; performing contour scanning on the stamping part sample to obtain multiple contour curves; The obtained multiple contour curves are scanned to determine the height of the high point defect of the stamping part sample.

[0038] In order to better understand the above-mentioned technical solution, the above-m...

Abstract

The invention discloses a method and a device for detecting a high-point defect of a surface product of a stamping part and a testing machine, and the method comprises the steps: adjusting a stamping part sample to a target state which is a horizontal placement state; performing contour scanning on the stamping part sample to obtain a plurality of contour curves; and the height of the high point of the stamping part sample is determined by comparing the scanned contour curves. According to the detection method, the height of the high defect of the stamping part is measured more accurately by scanning the profile curve of the stamping part.

Description

technical field [0001] The invention relates to the technical field of surface quality control of stamping parts, in particular to a detection method, device and testing machine for high point defects on the surface of stamping parts. Background technique [0002] Automobile stamping parts are auto parts that are cut out, stretched and formed to obtain specific shapes, specifications and functions. They are an important part of automobile manufacturing and have a decisive impact on the quality of vehicle assembly. In the process of automobile development, the surface quality of stamping parts seriously affects various indicators of the whole vehicle, including the cost of the whole vehicle, the production efficiency of the painting workshop and the quality of the whole vehicle, or investing manpower to repair the parts will also cause A large amount of capital investment, especially the manual repair of galvanized sheets, will cause the anti-corrosion ability of the parts to...
