Embodiment
The invention will now be described in further detail with reference to the accompanying drawings.
As shown in Figures 1 to 9, a kind of eccentric processing fixture, including clamp body 1, one end are articulated with fixture by hinge 16
Bottom plate 2 on body 1, indexing set 3 is installed with the other end of bottom plate 2 by screw, and indexing set 3 is provided with two jacks 4 and 5,
Positioning sleeve 6 is provided with clamp body 1, one end of a latch 7 is connected through jack 4 with positioning sleeve 6 by screw thread；Phase on a base plate 2
To be provided with fixing clip 8 and movable clip block 9, fixing clip 8 and movable clip block 9 provided with the arc clamping face with work piece match,
Fixing clip 8 is connected firmly with bottom plate 2 by four screws, and one end of movable clip block 9 is articulated with bottom plate 2 by hinge 10, activity
The other end of fixture block 9 is provided with through hole 11, and the two lateral walls of the through hole 11 are to be provided with plane, the corresponding bottom plate 2 of the through hole 11
Bushing 12, one end of a cam pin 13 is inserted in the bushing 12 in bottom plate through through hole 11, and the eccentric segment 13a of cam pin 13 is located at
In through hole 11, eccentric segment 13a rotating diameter is more than the spacing of the two lateral walls of through hole 11, fixing clip 8 and movable clip block 9
Two ends are equipped with step 8a or 9a, and step 8a and 9a overlaps in the axial direction of cam pin, the both ends step of movable clip block 9
9a is between the end step 8a corresponding with fixing clip of bottom plate 2 is axially located；Between fixing clip 8 and movable clip block 9
Backing plate 14 is fixedly connected with by screw on bottom plate 2；
In use, first rotating backward cam pin 13, its eccentric segment 13a is contacted with the left side wall of through hole 11, reverse promotion activity
Fixture block 9 rotates, it is separated with fixing clip 8, the end of workpiece can be now put between fixing clip 8 and movable clip block 9,
Cam pin 13 is rotated forward again, and its eccentric segment 13a is contacted with the right side wall of through hole 11, forward direction promotes movable clip block 9, make it to fixation
