Description

Coaxiality is fast quick inspection jig Technical Field The application relates to the technical field of inspection jigs, in particular to a quick coaxiality inspection jig. Background In the field of machining, the coaxiality of an inner hole is an important index for measuring the precision of a columnar metal part, and the precision is directly related to the running stability and the service life of the assembled part. If the coaxiality deviation of the inner hole is too large, the problems of blocking, wearing and even breakage and the like of the part in the running process can be caused. Therefore, in order to ensure the quality of products, the high-efficiency and accurate detection of the coaxiality of the inner holes of the columnar metal parts becomes an indispensable link in the production process. The prior art inner hole coaxiality quick inspection jig is the same as the coaxiality detector. The jig generally comprises a driving device, a positioning component, a dial indicator detection shaft and the like. During operation, the columnar metal to-be-detected piece is placed on the positioning assembly, the to-be-detected piece is driven to rotate around the axis of the positioning assembly through the driving device, the dial indicator detection shaft is inserted into the inner hole of the to-be-detected piece, and the dial indicator detection shaft is attached to the inner wall of the inner hole. Along with the rotation of the part to be detected, the dial indicator can detect the radial runout of the inner hole wall in real time, and then the coaxiality condition of the inner hole is obtained through calculation. Aiming at the related technology, the inventor considers that the columnar metal to-be-detected piece is easy to move along the length direction of the columnar metal to-be-detected piece in the detection process, and the movement can cause the relative position of the detection shaft of the dial indicator and the inner hole to change, so that the radial runout detected by the dial indicator is inaccurate, and the detection result of the coaxiality of the inner hole is further influenced.
