Abstract
The invention discloses a bolt-type small end locating mechanism for conical sleeve machining. The bolt-type small end locating mechanism comprises elastic sleeves, an expanding body, a driving rod, a supporting frame, a limiting block, a guide pipe, a cover plate, a spring and a bolt. The elastic sleeves are sleeved with annular grooves in the expanding body. A sliding groove is formed in the limiting block in the radial direction, one end of the expanding body is arranged in the sliding groove, and the driving rod is arranged in the expanding body and extends out of the limiting block. Taper structures are arranged at the inner circle of the expanding body in the axial direction, and cones matched with the taper structures are arranged at the outer circle of the driving rod. A first through hole is formed in the top of the limiting block, one end of the guide pipe is fixed to the top of the supporting frame, the cover plate is fixed to the other end of the guide pipe, and one end of the bolt penetrates the supporting frame and corresponds to the first through hole. The spring is located between the cover plate and a circular truncated cone arranged on the outer wall of the bolt.

Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the present invention is described in more detail.
As shown in Figures 1 to 3, bolt-type taper sheath processing small end detent mechanism, comprises resilient sleeve 1, expansion body 2, drive rod 3, bracing frame 4, the limited block 5 being arranged on expansion body 2 one end, conduit 9, cover plate 10, spring 11 and latch 12.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 16 and to be rotatably assorted with bracing frame 4.The top of limited block 5 arranges a through hole I 13, and the top of bracing frame 4 arranges a through hole II.One end of conduit 9 is fixed on the top of bracing frame 4, and cover plate 10 is fixed on the other end of conduit 9, latch 12 through conduit 9 and cover plate 10 and with conduit 9 and cover plate 10 matched in clearance, one end of latch 12 is corresponding with through hole I 13 through through hole II.Spring 11 to be enclosed within latch 12 and to be positioned at conduit 9, and one end of spring 11 is pressed on cover plate 10, on the round platform 14 that the outer wall that the other end is pressed in latch 12 is arranged.Latch 12 is positioned at round platform 14 and arranges a pin hole 18 with the middle part of the other end of latch 12.
