As further improvement of the utility model, being provided with lining in base plate, one end of described cam pin inserts in this lining in base plate；Lining and cam pin are the most replaceable after wearing and tearing, and can ensure the precision of fixture for a long time, increase the service life；
As further improvement of the utility model, being provided with positioning sleeve in the hole, location of clamp body, one end of described latch is passed through a jack and is connected by screw thread with positioning sleeve；Both it had been conveniently replaceable positioning sleeve and latch, latch can have been positioned again；
As further improvement of the utility model, the base plate between fixing fixture block and movable clip block is fixedly connected with backing plate by screw；The end face of different workpieces can be positioned by adjusting backing plate, expand the scope of application；
In sum, this utility model not only low cost, clamping are easy, efficiency is high, and machining accuracy is high, it is ensured that product quality.

Detailed description of the invention
Below in conjunction with the accompanying drawings this utility model is described in further detail.
As shown in Figures 1 to 9, a kind of eccentric processing fixture, the base plate 2 being articulated with on clamp body 1 by hinge 16 including clamp body 1, one end, it is installed with indexing set 3 by screw in the other end of base plate 2, indexing set 3 is provided with two jacks 4 and 5, being provided with positioning sleeve 6 in clamp body 1, one end of a latch 7 is connected by screw thread through jack 4 with positioning sleeve 6；nullOn a base plate 2 relative to be provided with fixing fixture block 8 and movable clip block 9，Fixing fixture block 8 and movable clip block 9 are provided with the arc clamping face with work piece match，Fixing fixture block 8 is connected firmly by four screws with base plate 2，One end of movable clip block 9 is articulated with on base plate 2 by hinge 10，The other end of movable clip block 9 is provided with through hole 11，The two lateral walls of this through hole 11 is plane，It is provided with lining 12 in the base plate 2 of this through hole 11 correspondence，One end of one cam pin 13 inserts in the lining 12 in base plate through through hole 11，The eccentric segment 13a of cam pin 13 is positioned at through hole 11，The rotating diameter of eccentric segment 13a is more than the spacing of through hole 11 two lateral walls，The two ends of fixing fixture block 8 and movable clip block 9 are equipped with step 8a or 9a，Step 8a and 9a overlaps in the axial direction of cam pin，The both ends step 9a of movable clip block 9 is being axially located between the end step 8a that base plate 2 is corresponding with fixing fixture block；It is fixedly connected with backing plate 14 by screw on base plate 2 between fixing fixture block 8 and movable clip block 9；
