Abstract

The invention relates to a detector for detecting different sections of a transmission shaft jacket fairway interval, which is a detection tool used for a car constant velocity universal joint transmission shaft jacket fairway, a cylindrical hole is arranged on a working table plate, a step sliding column is arranged in the cylindrical hole, a spring A is sleeved on the step sliding column, and the lower end of the step sliding column is fixedly connected with a baffle block; the upper end of the stepped sliding column is fixedly connected with the upper cover, a transverse column sleeve is arranged between the stepped sliding column and the upper cover, a connecting rod B is fixedly arranged in one end of the transverse column sleeve, the other end of the connecting rod B is fixedly connected with a steel ball B, a connecting rod A in sliding connection is arranged in the other end of the transverse column sleeve, and the other end of the connecting rod A is fixedly connected with a steel ball A. A longitudinal column sleeve is arranged in the stepped sliding column. The longitudinal column sleeve and the transverse column sleeve are communicated and perpendicularly and fixedly connected, the transmission assembly is arranged in the longitudinal column sleeve and the transverse column sleeve, a meter rod of the dial indicator is fixedly arranged in the longitudinal column sleeve, a contact of the dial indicator is in contact with the lower end face of the transmission assembly, and the vertical face of the upper end of the transmission assembly is in contact with the connecting rod A. The technology is accurate in data detection and high in efficiency.
