In order to meet the above requirements, use of the following processes and tooling.
1. First of all cylindrical processing A good benchmark, in the shaft both ends of the craft to remain 50mm long 25mm chuck, chuck and A baseline requirements and the step surface with the A axis perpendicular to the base.
2. The two ends of the shaft into the chuck and milling bian 42h6, see Figure 1, require bian and A center-symmetric and the two ends of the base parallel.
3. Tooling production: Card tank 2, as shown in Figure 2 require B5 groove 42H7 symmetrical with the center hole, groove perpendicular to the face with the center hole.
4. Will be canned in the shaft at both ends of cards, the card should be directed to the same eccentric tank, through the card slot with the axis of tank co-bian 42H7/h6 to control the direction of the eccentricity; cans on the card by adjusting the clamping screw can be regulate the amount of eccentricity; make cards face tank level surface with the axis of compaction to ensure that the center axis parallel with the card center tank.
5. In the car with double bed, the top fixture, four-claw clamping card pot rotation, in order to use Form A baseline measurement of cylindrical ends, adjust the screws on the card cans to adjust to different eccentric volume, turning the eccentric cylindrical to size.
6. When the eccentric shaft machining process chuck exhausted to cut out both ends.
Such processing method is simple, reliable method to avoid the cumbersome process of the original (boring to play center hole), can be applied to require the same direction, a number of eccentric eccentric axis machining.
