Method for reducing double pin positioning error

In the production, the workpieces with two parallel holes are often used to locate the workpiece. In order to reduce the displacement and the angle error, we have adopted the following methods in production, and the effect is better. The original fixed diamond pin 3 (Fig. 1) is made into a tapered movable diamond pin (Fig. 2). The maximum outer diameter of the diamond pin is larger than the outer diameter of the workpiece positioning hole, and the maximum outer diameter portion must be higher than the clamp. Diamond pin
