Background

In modern workpiece processing equipment, detection equipment is often used for detecting the specifications of the processed workpieces, so that each processed workpiece meets the production standard.

Patent CN201620991005.X discloses a semi-finished axle thread three-hole position degree gauge, which is used for measuring the radius from each of three shaft end screw holes 8-2 to a central taper hole 8-1 and the connecting line distance between the axes of each of the three shaft end screw holes 8-2 by using a vernier caliper, and comparing with a theoretical value calculated by trigonometric function solution to obtain an error value of the processing amount once. However, since the machined central taper hole 8-1 and the three shaft end screw holes 8-2 are respectively located on different height planes, human errors are inevitably introduced into the measuring result of the vernier caliper, and further the measuring error exceeds a theoretical error allowable range, so that the product quality of the semi-finished axle 8 cannot be effectively guaranteed. The centering ball head at the top end of the front section of the center shaft positioning pin is inserted into the center taper hole, so that the axis extension line of the mandrel positioning sleeve passes through the center of the center taper hole, and the axis of the mandrel positioning sleeve is positioned. And further judging whether the respective axis deviation errors of the three shaft end screw holes which are detected currently accord with a given tolerance range by detecting whether three stud gauge rods which are respectively and coaxially connected with the three shaft end screw holes which are detected can be inserted into a corresponding gauge rod sleeve or not.
