Description
本实用新型涉及一种激光检测治具，属于检测治具技术领域。The utility model relates to a laser detection fixture, which belongs to the technical field of detection fixtures.
现有的激光式板件厚度检测治具一般只能检测出过厚的板件，而符合厚度标准的板件和小于厚度标准的板件均作为合格品出件。而对于一些要求严格的精密设备，对板件的厚度要求高，过薄过厚均可带来质量问题，如汽车钢板，汽车钢板厚度问题一直是国内消费者比较关心的问题，而并不是钢板越厚汽车就越安全，而是应该根据车体不同部位的受力情况，选择不同厚度的钢板，这就需要严格控制车体不同受力部位的钢板厚度。Existing laser-type plate thickness detection fixtures generally can only detect excessively thick plates, while plates that meet the thickness standard and plates that are smaller than the thickness standard are all produced as qualified products. For some precision equipment with strict requirements, the thickness of the plate is required to be high. Too thin and too thick can bring quality problems, such as automotive steel plates. The thickness of automotive steel plates has always been a concern of domestic consumers, not steel plates. The thicker the car, the safer it is. Instead, steel plates of different thicknesses should be selected according to the stress of different parts of the car body, which requires strict control of the thickness of the steel plates in different parts of the car body.
本实用新型所要解决的技术问题是，提供一种快速检出过厚板件的激光检测治具；进一步地，本实用新型提供一种可快速检出过薄板件的激光检测治具；更进一步比，本实用新型提供一种便于板件取出的激光检测治具。The technical problem to be solved by the utility model is to provide a laser detection fixture that can quickly detect over-thick plate parts; further, the utility model provides a laser detection fixture that can quickly detect over-thin plate parts; further In contrast, the utility model provides a laser detection fixture which is convenient for taking out the plate.
