Wherein, the outer surface of described collet mainly comprises male cone (strobilus masculinus) I and male cone (strobilus masculinus) II, described male cone (strobilus masculinus) II is adaptive with the taper hole of matrix, described matrix is provided with external screw thread with taper hole with the outer cylinder surface of one end, be provided with internal thread and inner conical surface in the endoporus of described fastening nut, the external thread rotary merga pass inner conical surface of described internal thread and matrix compresses male cone (strobilus masculinus) I and to collet transmission of pressure.
Further, described matrix one end is provided with screwed hole, and described positioning key is provided with screw hole, screws be fixedly connected with matrix by positioning key after bolts through bolt holes with screwed hole.
Further, described matrix is provided with mounting hole, described mounting hole and taper hole through.
The utility model advantage compared with prior art:
1, the male cone (strobilus masculinus) II of collet is suitable with the taper hole of matrix, can realize the centering object to part reference axis more accurately;
2, the internal thread of fastening nut and matrix external thread rotary merga pass inner conical surface compress male cone (strobilus masculinus) I and to collet transmission of pressure, collet pressurized shrinks Clamp blocks reference axis then, and its clamping is firmly stable, improves the machining accuracy of workpiece;
3, matrix one end is fixedly connected with the work top of lathe by positioning key, the moment of torsion produced when positioning key not only bears fastening nut degree of tightness part, will guarantee the tram of clamp body on lathe table top simultaneously;
4, or clamping reference axis shorter situation softer for part material, the utility model efficiently solves part and crushes the problems such as distortion, not clamping, positioning precision and repetitive positioning accuracy be inaccurate, simple to operate, there is quick-replaceable function, greatly improve operating efficiency.
5, on matrix, mounting hole is shaped with, can conveniently to the cleaning of chip and foreign material in collet and taper hole, the face, long limit of mounting hole simultaneously, also can as the placed side of part axial workpiece axial location part.
