Application of spherical support in combined fixture

The spherical support (Fig. 1) and the combined fixture components can better solve the problem of bevel inclined hole machining. When processing the cast steel die base (Fig. 2), the weight of the workpiece is 85kg. It is required to position the F face and the orientation of the 2-R40. If the bevel P_1 of 1:8 and 1:10 is machined on the vertical milling machine, the workpiece The positioning surface should form a β angle with the bottom surface of the fixture (Fig. 3), and the β angle is based on the angle between the P_1 and the F plane.
