Preferably, the clamping arc diameter of clamp body is greater than the body diameter 0.1mm of chip cylindrical parts, and the clamping arc diameter of clamp is greater than the body diameter 1 ~ 2mm of chip cylindrical parts.
Preferably, be provided with mounting spring between clamp body and clamp, mounting spring correspondence is set on lead.
Preferably, clamp body lower end is provided with the tapered cylinders for connecting machine tool, and tapered cylinders is provided with inner groovy and is two flap-type structures along bus.
Preferably, the top of the stepped boss of clamp body is fixedly installed spring pressuring plate, and the free end of spring pressuring plate extends to above grasping part.
Preferably, to be positioned at below grasping part and the ledge surface of next-door neighbour's grasping part is provided with transverse concave groove.
Compared with prior art, the present invention has following useful technique effect:
The present invention is less than the bicircular arcs positioning and clamping structure of 180 ° by have employed radian, realize the accurate positioning of workpiece, multistage manufacturing processes, eliminates the superposition of workpiece multiple clamping manufacturing tolerance simultaneously.Install simple, precision is high, is convenient to Workpiece clamping and location.
Further, the cone structure of clamp body, by the setting of hollow and two flap-type, makes the easy installing/dismounting that fixture realizes at lathe.
Further, clamp body base has through hole, reduces the dither effect that clamp body is arranged on the clamp body that gas causes when gas-static turntable uses while reducing fixture own wt.
Further, clamp adopts screw-driving and adopts spring pressuring plate to the warping phenomenon preventing clamp in clamping process.
Further, clamp adopts Z-type to match with the step structure of clamp body, can ensure the stability of clamping process.
Further, have transverse concave groove on the top of clamp body, also can take out by the undamaged of workpiece easily while realizing machining small.

Detailed description of the invention
Below in conjunction with specific embodiment, the present invention is described in further detail, and the explanation of the invention is not limited.
Chip cylindrical parts of the present invention bores mill Special Fixture for Machining assembly, can realize easy clamping and the high precision manipulation of fixture; Be applicable to chip cylindrical parts and carry out the processing of ultraprecise brill mill.
The present invention is adopted by the trade union college position of clamp body 1 and clamp 8 and is less than the designed arc-shaped appearance of 180 ° and the arc diameter of clamp 8 is greater than clamp body 1 arc diameter, differ by more than 1 ~ 2mm, the circular arc of clamp body 1 plays positioning action, the circular arc of clamp 8 plays the effect stepped up, clamped contact is linear contact lay, increases the stability in workpiece process.
Have lead 6,11 between clamp body 1 and clamp 8, pinching screw 9 and mounting spring 10 realize Workpiece clamping and unclamp.
The installation of clamp body 1 on lathe adopts the location of taper hole.
Clamp body 1 and clamp 8 surface have spring pressuring plate 2,4 to ensure the parallel motion of chip cylindrical parts in clamping.
Concrete, as shown in Figure 1, clamp body 1 and clamp 8 to be connected with pinching screw 9 composition fixture by lead 6,11.Clamp 8 is led by lead 6,11 and clamps.Adopt cone and inner groovy in the bottom of clamp body 1, and have hole bottom clamp body, to alleviate the weight of clamp body, increase structural strength and the rigidity of clamp body, positioning precision is high, and location is convenient; Clamp body 1 bottom pyramidal cylinder is two flap-type hollow structures, has certain Flexible change ability, therefore in fixture clamping process, more easily ensures coordinating and positioning precision of fixture and lathe.
