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, a kind of fitting device of fixing taper sheath processing small end, 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, support 9, screw rod 10, spring 11 and locking nut 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, support 9 is fixedly installed on bracing frame 4, the top of bracing frame 4 arranges through hole II, support 9 is arranged through hole III, screw rod 10 through support 9 through hole III and in through hole III matched in clearance, one end of screw rod 10 is corresponding to through hole I 13 through hole II, spring 11 is enclosed within screw rod 10, one end of spring 11 is pressed on support 9, the other end of spring 11 is pressed on round platform 14 that screw rod 10 is arranged, locking nut 7 be positioned at the outside of support 9 and rotation set on the other end of screw rod 10.
