Description

Technical Field

[0001] The utility model belongs to the technical field of detection tooling, and particularly relates to a roughness detection tooling of a gantry structure. Background Art

[0002] Cold-rolled coils are often used in the manufacture of home appliances such as automobiles, refrigerators, and washing machines because of their smooth surface. They are also used in some industrial equipment and various building materials. Since cold-rolled coils have high requirements for the surface, their surface roughness will directly affect the quality and price of the product. Therefore, in addition to the automatic detection module on the line, the inspectors also need to conduct surface roughness sampling inspections on the processed cold-rolled coils. By increasing the manual sampling and automatic detection to form a double guarantee, the quality of the final shipped products can be ensured. At present, for the surface roughness sampling inspection of cold-rolled coils, the inspectors will use a handheld detector to inspect the surface of the sample plate; however, due to structural reasons, this handheld detector can only perform a small range of inspections from the edges of the sample plate, and cannot directly obtain data from the center area of ​​the coil. It can only ensure the accuracy of the data by continuing to cut the plate and continue to detect, which is very inconvenient. Therefore, there is a certain market demand for designing a detection tool that can cooperate with the detector to comprehensively detect the roughness of the coil. Summary of the invention
