In order to solve the problems of the technologies described above, the utility model have employed following technical scheme:

Taper sheath processes little end positioning device, comprises resilient sleeve, expansion body, drive rod, bracing frame and is arranged on the limited block of expansion body one end; The outer surface of described expansion body is at least provided with two annular grooves arranged along its circumferencial direction, and described resilient sleeve is enclosed within annular groove; Described limited block radial direction arranges chute, and the cross section of expansion body is the lobe ring structure of at least three lobes, and lobe ring one end of lobe ring structure is arranged in chute with the mode single-degree-of-freedom that can radially slide, and described drive rod to be arranged on vertically in expansion body and to pass limited block; Described expansion body inner circle arranges tapered configuration vertically, and the cylindrical of drive rod arranges the bullet matched with tapered configuration, and described tapered configuration arranges internal thread, and bullet arranges the external screw thread matched with the internal thread of tapered configuration; The traversing through end of described drive rod to be arranged on bracing frame and to be rotatably assorted with bracing frame; The top of described limited block arranges a draw-in groove, support frame as described above is arranged clamp that is rotating and that may be stuck in draw-in groove.

As a kind of preferred version of the present utility model, the traversing through end of described drive rod is fixedly installed the swiveling wheel driving drive rod, and the outer surface of swiveling wheel arranges anti-slip veins.

The beneficial effects of the utility model are: taper sheath is processed little end positioning device and can be positioned the small end of taper sheath, the chuck of lathe is without the need to too gripping the large end of taper sheath, avoid the large end clipping broken taper sheath, also avoid being distorted at the outer bowlder taper sheath of car taper sheath simultaneously.

Detailed description of the invention

Below in conjunction with the drawings and specific embodiments, the utility model is described in more detail.

As shown in Figures 1 to 3, taper sheath processes little end positioning device, comprises resilient sleeve 1, expansion body 2, drive rod 3, bracing frame 4 and is arranged on the limited block 5 of expansion body 2 one end.The outer surface of expansion body 2 is at least provided with two annular grooves arranged along its circumferencial direction, and in the present embodiment, expansion body 2 is provided with two annular grooves, resilient sleeve 1 is enclosed within annular groove.Limited block 5 is platy structure, limited block 5 radial direction arranges chute 6, the cross section of expansion body 2 is the lobe ring structure of at least three lobes, the expansion body 2 of the present embodiment adopts straight cut pintongs ring, lobe ring one end of lobe ring structure is arranged in chute 6 with the mode single-degree-of-freedom that can radially slide, and drive rod 3 to be arranged on vertically in expansion body 2 and to pass limited block 5.Expansion body 2 inner circle arranges tapered configuration 7 vertically, the present embodiment adopts two sections of inner circle tapered configuration, the cylindrical of drive rod 3 arranges the bullet 8 matched with tapered configuration 7, drive rod 3 is arranged two sections of bullets 8 matched with two sections of tapered configuration 7 respectively, in the present embodiment, tapered configuration 7 arranges internal thread, and bullet 8 arranges the external screw thread matched with the internal thread of tapered configuration 7.The traversing through end of drive rod 3 to be arranged on bracing frame 4 and to be rotatably assorted with bracing frame 4, and in the present embodiment, the traversing through end of drive rod 3 to be arranged on bracing frame 4 by bearing 12 and to be rotatably assorted with bracing frame 4.The top of limited block 5 arranges a draw-in groove 9, bracing frame 4 is arranged clamp 10 that is rotating and that may be stuck in draw-in groove 9.

The traversing through end of drive rod 3 is fixedly installed the swiveling wheel 11 driving drive rod 3, and the outer surface of swiveling wheel 11 arranges anti-slip veins, both laborsaving by turn swiveling wheel 11 rotation of drive rod 3, facilitates again.

When using this taper sheath to process little end positioning device, the small end of taper sheath 13 is placed in expansion body 2, as shown in Figure 4, clamp 10 on rotary support frame 4 makes clamp 10 be stuck in the draw-in groove 9 at limited block 5 top, turn drive rod 3, bullet 8 screws in tapered configuration 7, each lobe ring can be made to move along the synchronous radial single-degree-of-freedom of chute of limited block 5, thus the diameter of resilient sleeve 1 is increased, can position the small end of taper sheath 13, clamp 10 behind location on rotary support frame 4 makes clamp 10 depart from the draw-in groove 9 at limited block 5 top, the large end of chuck without the need to too gripping taper sheath 13 of lathe, avoid the large end clipping broken taper sheath 13, also avoid being distorted at the outer bowlder taper sheath 13 of car taper sheath 13 simultaneously.

What finally illustrate is, above embodiment is only in order to illustrate the technical solution of the utility model and unrestricted, although be described in detail the utility model with reference to preferred embodiment, those of ordinary skill in the art is to be understood that, can modify to the technical solution of the utility model or equivalent replacement, and not departing from aim and the scope of technical solutions of the utility model, it all should be encompassed in the middle of right of the present utility model.
