Detection jig

Abstract

The invention relates to the technical field of detection jigs, and discloses a detection jig. The detection jig comprises a carrying table, a bearing beam and a clamping unit. A detection through hole is formed in the carrying table, a fixing part is arranged on the carrying table in a protruding mode, and the fixing part is located on one side of the detection through hole in the first direction; the bearing beam is arranged at the detection through hole and can bear a part, and one end of the bearing beam is connected to the fixing part and extends in the first direction so as to divide the detection through hole into two detection channels; the clamping unit is arranged on the carrying table and located on the other side of the detection through hole in the first direction, and the clamping unit can be close to or away from the fixing part in the first direction so as to clamp or loosen the part. According to the detection jig provided by the invention, the part can be stably fixed on the detection jig, the possibility of relative displacement between the part and the detection jig is reduced, and the accuracy of part detection is improved.

Description

technical field [0001] The invention relates to the technical field of detection jigs, in particular to a detection jig. Background technique [0002] The camera bracket needs to undergo various quality inspections before leaving the factory. Generally, before the camera bracket is tested, the camera bracket is fixed on the testing fixture to prevent the camera bracket from moving during the testing process. After the camera bracket has passed one of the inspections, it is necessary to use equipment such as manipulators to grab the inspection jig, and move the jig and camera bracket to the subsequent inspection station as a whole. At present, there is a light hole on the camera bracket, and the size of the light hole needs to be detected, that is, the front and back of the fixed camera bracket need to be exposed. Therefore, a detection hole is opened on the jig to ensure that the front and back of the camera bracket are Both can be exposed, and the camera bracket is fixed ...

AI Technical Summary

Problems solved by technology

At present, there is a light hole on the camera bracket, and the size of the light hole needs to be detected, that is, the front and back of the fixed camera bracket need to be exposed. Therefore, a detection hole is opened on the jig to ensure that the front and back of the camera bracket are Both can be exposed, and the camera bracket is fixed on the jig only by the claws on the left and right sides of the camera bracket, and in order to avoid leaving clamp marks on the camera bracket, the clamping force on the camera bracket is relatively small. The friction between the camera bracket and the jaws is small, and the camera bracket is more likely to move relative to the fixture during the movement process, causing the detection point on the camera bracket to move, reducing the accuracy of camera bracket detection and affecting the product. pass rate
