Further, described protruding tooth is uniform at least two of annular, described breach and the corresponding setting one by one of described protruding tooth.
Further, between described ringfeder and described positioning seat, be provided with setting circle pin.
Further, between described positioning seat and described pull bar, be provided with holding screw, and be provided with locating slot corresponding to described holding screw on described pull bar.
Further, described tapered face fit structure comprises and is arranged on the outer conical surface of described positioning seat end and is arranged on the internal conical surface on described ringfeder.
The beneficial effects of the utility model are:
The utility model is convenient for changing the gear-hobbing clamp mechanism of ringfeder, by the stopper slot being formed by gland and bulge loop is set on pull bar, and on ringfeder, be arranged at stopper slot coordinate protruding tooth, when assembling, utilize tapered face fit structure that ringfeder is sleeved on positioning seat, then pull bar is inserted in positioning seat, and breach is alignd protruding tooth is fallen in stopper slot with protruding tooth, after ringfeder being rotated to the angle of setting, fix, so just complete the installation of ringfeder, the unloading process of ringfeder is contrary with said process; In summary, gear-hobbing clamp mechanism structure of the present utility model is simple, and facilitates assembling and the dismounting of ringfeder, is convenient to change.
Brief description of the drawings
In order to make the purpose of this utility model, technical scheme and beneficial effect clearer, the utility model provides following accompanying drawing to describe:
Fig. 1 is the structural representation that the utility model is convenient for changing the gear-hobbing clamp mechanism for implementing example of ringfeder;
Fig. 2 is the structural representation of pull bar;
Fig. 3 is the structural representation of ringfeder.
Detailed description of the invention
Below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described in detail.
As shown in Figure 1, be convenient for changing the structural representation of the gear-hobbing clamp mechanism for implementing example of ringfeder for the utility model.The present embodiment is convenient for changing the gear-hobbing clamp mechanism of ringfeder, comprise pull bar 1, be fixedly set in the positioning seat 2 on pull bar 1 and be sleeved on the ringfeder 3 on positioning seat 2, the pull bar 1 of the present embodiment is provided with locating slot 1a, positioning seat 2 is provided with the holding screw 4 coordinating with locating slot 1a, for preventing that pull bar 1 from rotatablely moving with respect to positioning seat 2.One end of pull bar 1 is provided with the gland 5 for being fixed ringfeder 3, and the be provided with bulge loop 6 that extend radially outwardly adjacent with gland 5 on pull bar 1, between bulge loop 6 and gland 5, forms stopper slot 7.Between ringfeder 3 and positioning seat 2, be provided with tapered face fit structure, and one end of ringfeder 3 is provided with the protruding tooth 8 that extends radially inwardly and coordinate with stopper slot 7, the be provided with breach 9 that for protruding tooth 8 pass bulge loop 6 corresponding to protruding tooth 8 on bulge loop 6.Preferably, protruding tooth 8 is uniform at least two of annular, breach 9 and the corresponding setting one by one of protruding tooth 8, the protruding tooth 8 of the present embodiment be set to 3 also annular uniform, breach 9 annular corresponding to protruding tooth 8 is uniform is set to 3.The tapered face fit structure of the present embodiment comprises and is arranged on the outer conical surface of positioning seat 2 ends and is arranged on the internal conical surface on ringfeder 3, by adopting tapered face fit structure, in the time of pull bar 1 tension downwards, ringfeder 3 under gland 5 effect, also move downward and effect at tapered face fit structure under produce distortion, tensioner workpiece 11, in the time that pull bar 1 upwards loosens, ringfeder 3 moves upward under bulge loop 6 effects, tapered face fit structure is cancelled, and distortion is shunk, and can take off easily workpiece 11.
