To achieve the above object, the utility model provides following technical scheme：
A kind of turning attachment for fixing single-ended whorl work piece, including chuck body, locating piece and taper pin；The fixture sheet
Body is provided with the body pin-and-hole of axially extending bore and up/down perforation, and axially extending bore includes the screwed hole being threadedly coupled with the workpiece end of thread
Section；The locating piece is assemblied in axially extending bore, and locating piece is provided with the pin-and-hole of up/down perforation, taper pin be assemblied in body pin-and-hole and
The positioning to locating piece is realized in pin-and-hole.
A kind of above-mentioned turning attachment for fixing single-ended whorl work piece, the body pin-and-hole, pin-and-hole are respectively tapered hole, it
Size and taper match respectively with taper pin；The axially extending bore includes unthreaded hole section and screw thread hole section, when locating piece is determined
After in axially extending bore, a part for locating piece is located in the screw thread hole section of axially extending bore.
A kind of above-mentioned turning attachment for fixing single-ended whorl work piece, the longitudinal section of the chuck body is regular hexagon；
To be cylindrical, the diameter of its diameter and axially extending bore matches the locating piece.
Application method of the present utility model is：
First, locating piece is fitted into the axially extending bore of chuck body, taper pin inserted real in body pin-and-hole and pin-and-hole
Now to the positioning of locating piece；Then the end of thread of workpiece is screwed in the screw thread hole section of chuck body axially extending bore, due to positioning
A part for block is located in screw thread hole section, thus progressively screw workpiece be able to ensure that workpiece end of thread end face and locating piece it is tight
It is close to offset；The turnery processing of workpiece can now be carried out；After machining, the top of locating piece and workpiece while unloading taper pin
Pressure eliminates immediately, so as to the convenient dismounting for carrying out workpiece；The utility model taper pin and taper body pin-and-hole, pin-and-hole
Cooperation may insure that locating piece tightly offsets all the time with workpiece in turning process, can prevent work while crudy is ensured
Micro- deformation of part；The chuck body of hexahedron structure facilitates the clamping of lathe clamping jaw.
The beneficial effects of the utility model are：
The utility model can ensure to hold out against single-ended whorl work piece, the convenient turnery processing to the workpiece other end；Turning
After the completion of dismounting taper pin can easily and fast complete the dismounting of workpiece, greatly improve operating efficiency, at the same taper pin and this
The cooperation of body pin-and-hole, pin-and-hole may insure that locating piece and workpiece tightly offset all the time in turning process, prevent micro- shape of workpiece
Become.

Embodiment
Fig. 1~Fig. 5 shows, a kind of turning attachment for fixing single-ended whorl work piece of the utility model, including chuck body 1,
Locating piece 2 and taper pin 3；The longitudinal section of chuck body 1 is regular hexagon；Chuck body 1 is provided with axially extending bore 4 and up/down perforation
Body pin-and-hole 5, the unthreaded hole section of axially extending bore 4 including left side and the screw thread hole section on right side, the end of thread of screw thread hole section and workpiece 7
Threaded connection；Body pin-and-hole 5 is bellmouth, and the size and taper of its size and taper respectively with taper pin 3 match；Locating piece
2 be cylinder, and the diameter of its diameter and the axially extending bore 4 of chuck body 1 matches, and locating piece 2 is assemblied in axially extending bore 4,
