Specific embodiment
Method of the present invention step is as follows：
1) cam parts positioning is clamped on special purpose device so as in screwed hole be first in lathe center of rotation；
The relative position of screwed hole is determined using the geometrical relationship being processed between hole and locating surface, location hole on workpiece；
2) another processed screwed hole is caused again to be at the center of rotation of lathe by rotary index；Extend in " eight " word
The radially-arranged two screw thread centerline holes of shape make which meet at certain point, arrange indexing mechanism as index center to realize this with this point
Function；
3) above-mentioned two action is repeated, two screwed holes to be processed are made respectively in precalculated position, using numerically controlled lathe
The final processing of two screwed holes can be completed.
Referring to Fig. 2, the structure of the specific embodiment of the invention includes device body 1, be provided with device body 1 index dial 2,
Apotting spindle 3 and deck 13, index dial 2 passes through apotting spindle 3 and deck 13 connects, and apotting spindle 3 is arranged on index dial 2 and card
The center of seat 13, index dial 2 can be rotated around heart axle 3, and centrally disposed intentionally neck bush 10 of deck 13, apotting spindle 3 are placed in heart axle
In bushing 10.Index dial 2 and 13 both sides of deck are symmetrically respectively arranged with limiting and guiding device, and limiting and guiding device includes spacing lining
