Technical Field

The utility model relates to the technical field of automobile welding clamps, in particular to an automobile part detection device.

Background

Automotive body panels include front and rear bumpers, front fenders, doors, trunk lids, and the like, and prior to welding these parts, it is necessary to clamp the automotive parts using a welding jig prior to welding. The prior art discloses an mistake proofing detects welding jig, and welding jig's location clamping unit is fixed on the bottom plate, is equipped with the sensor on the support of location clamping unit, and the sensor links to each other with programmable control system. The operator puts each subassembly into welding jig, and each location clamping unit compresses tightly the work piece, and every sensor response corresponds annex, indicates in order to ensure that auto parts installs in place on welding jig according to the pilot lamp of control panel.

In the technical scheme, the sensor is fixedly installed on the positioning and clamping unit of the welding fixture, when the automobile body part is positioned on the positioning structure of the welding fixture, the surface, facing the sensor, of the automobile part is the detection surface, and the sensor determines that the automobile part is placed in place by detecting the existence of the detection surface. Because the sensor has a certain detection range, the distance between the detection surface of the parts of different vehicle types positioned on the welding fixture and the measuring head of the sensor is different. The distance between the parts of a part of the vehicle type and the measuring head of the sensor is far after the parts are positioned on the welding fixture, so that the measuring head of the sensor cannot detect the existence of the parts, if the parts of the vehicle type are detected by the measuring head of the sensor by installing the sensor at a higher position on the welding fixture, the distance between the parts of other vehicle types and the measuring head of the sensor is too close after the parts of the vehicle type are positioned on the welding fixture, and the parts easily collide or scratch the measuring head of the sensor when positioned on the welding fixture, so that the sensor is damaged; moreover, the welding station is very harsh in environment, a large amount of welding slag can fall and be accumulated on the measuring head of the sensor, so that the sensor can erroneously detect the welding slag as an automobile part, and the situation of false detection occurs.
