Description

Technical Field

[0001] The invention relates to the technical field of detection tooling, in particular to a detection tooling for mis-riveted studs. Background Art

[0002] The self-clinching stud is a fastener used for sheet metal, thin plates, chassis, and cabinets. The self-clinching stud has a hexagonal shape at one end and a cylindrical shape at the other end. There is a back-cut groove between the hexagonal side and the cylindrical shape, and its inner shape is an internal thread. The hexagonal head is pressed into the preset hole of the thin plate by a press (the aperture of the preset hole is generally slightly larger than the cylindrical outer diameter of the self-clinching stud) to cause plastic deformation around the hole. The deformed part is squeezed into the back-cut groove of the self-clinching nut column, so that the self-clinching nut column is riveted to the thin plate, thereby forming an effectively fixed internal thread on the thin plate.

[0003] At present, the known methods of checking missing studs on stamped parts are to use manual visual inspection and caliper measurement tools. The recognition of the rivet stud structure on the visually inspected parts is low when the number and types are large, and visual fatigue inspection will also result in omissions. Using caliper inspection cannot meet the efficiency requirements of mass production. Summary of the invention
