Description

Technical Field

[0001] The utility model relates to the technical field of laser detection, in particular to a laser detection device for riveting tooling. Background Art

[0002] Riveting is a fixing technique that is often used to fix studs on plates such as iron and aluminum plates that cannot be welded. It is also a very common fixing method and is usually used in electronic mechanical equipment, metal sheet industry products, hardware stamping, or copper, aluminum, plastic and other materials.

[0003] When riveting existing metal plates, laser spotlights are used to project cross marks to assist in ensuring that the rivets are accurately punched in the designated locations. However, some metal plates are pre-set with equidistant and easy-to-install holes and slots on their surfaces, which greatly reduces the probability of rivet placement errors. However, some metal plates do not have holes and slots installed, so workers can only rely on marking and feeling to punch. Moreover, accurate inspection cannot be performed after punching, which can easily lead to quality problems in the riveting tooling.

[0004] Therefore, a laser detection device for riveting tooling is now designed to solve this type of defect. Utility Model Content
