technical field

The utility model relates to the technical field of stamping, in particular to a detection device for stamping accessories.

Background technique

Stamping products rely on presses and molds to apply external forces to sheets, strips, pipes, and profiles to cause plastic deformation or separation to obtain the desired shape and size.

Some existing auto parts are stamped products. For some stamped products with more complex structures, when the size of the stamped product deviates, it will make it difficult to assemble the stamped product. The size is within the appropriate error range, and the hand-held size measuring instrument is often used to measure the assembly gap and the gap detection separately during the inspection.

The above-mentioned prior art solutions have the following defects: when using a hand-held size measuring instrument for measurement, it is necessary to check multiple positions, resulting in a large number of measurements, which leads to a slow detection speed by the inspectors.
