C. the back of clamp body and front are respectively equipped with clamping and positioning assembly C, D, the structure of assembly C, D is identical, index dial among assembly C, the D and slip cap are fixed on the clamp body by screw, by screw the top of sliding is housed in the slip cap, slip is equipped with the adjustment screw mandrel in the top, the front end that pushes up that slides is equipped with briquetting, adjusts on the screw mandrel handwheel is housed, and is equipped with on handwheel and the index dial and draws pin member assembly F;

D. on the inclined-plane, lower-left of clamp body, be provided with the structure tapered hole calibration assembly E identical with hexahedron calibration assembly B.

In the utility model, the installation site of hexahedron calibration assembly B can be exchanged with the installation site of clamping and positioning assembly D.

In clamping and positioning assembly C, D, also pivoted housing can be installed on the slip cap.

The utlity model has following advantage: 1, working (machining) efficiency height, easy to operate, safe and reliable, cost is low; 2, solved the turning problem of the rack porous bolt sphere of big screw, major diameter, coarse pitch; 3, present, the bolt sphere diameter of domestic maximum is 200mm, and the screw maximum gauge is M56, and uses the utility model anchor clamps, can process the bolt sphere of the above diameter of 1000mm on C650 lathe and vertical lathe, has developed the bright prospects of watering steel hollow bolt net.

Concrete structure of the present utility model is provided by drawings and Examples.

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is the vertical view of Fig. 1;

Fig. 3 has installed structural representation behind the tapered hole calibration assembly E for the utility model;
