Specific implementation mode
The method and step of the present invention is as follows：
1) cam parts are positioned on dedicated unit and is clamped, one of threaded hole is made first to be in lathe rotation center；
The relative position of threaded hole is determined using the geometrical relationship being processed between hole and positioning surface, location hole on workpiece；
2) another is made to be processed the rotation center that threaded hole again is at lathe by rotary index；It is in " eight " word to extend
The radially-arranged two screw thread centerline holes of shape make it meet at certain point, are put with this and indexing mechanism is arranged to realize this for index center
Function；
3) above-mentioned two action is repeated, so that two threaded holes to be processed is in precalculated position respectively, utilizes numerically controlled lathe
The final processing of two threaded holes can be completed.
Referring to Fig. 2, the structure of the specific embodiment of the invention includes device body 1, be provided on device body 1 index dial 2,
Apotting spindle 3 and deck 13, index dial 2 are connected by apotting spindle 3 and deck 13, and the setting of apotting spindle 3 is in index dial 2 and card
The center of seat 13, index dial 2 can be rotated around mandrel 3, and deck 13 is provided centrally with mandrel bushing 10, and apotting spindle 3 is placed in mandrel
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 that limit serves as a contrast
It is provided with bolt 5 in set 4, limiting bush 4 and compresses the spring 8 of bolt 5, limiting bush 4 is placed in index dial 2, and deck 13 is right
