Description
Technical field
The utility model relates to frock clamp field, particularly a kind of clamping apparatus for gear wheel processing.
Background technology
Gear is divided into axle class and dish class by tooth embryo shape, and generally adopt Double Tops pointed orifice to locate during working shaft-like, gear-hobbing clamp generally adopts combining structure, namely be made up of clamp base and axle, the fixture of same specification, base can install the axle of different size, has the low advantage easy to adjust of cost.Common gear-hobbing clamp base is divided into 2-3 kind according to the large I of workpiece, select by the reference circle of workpiece, a part often needs through several machine tooling, Gear Processing is also like this, as machining shaft gear, need through turning, grinding, tooth Profile Machining, the operations such as pincers processing, and these manufacturing procedures are communication with one another, therefore add and must consider man-hour comprehensively, the feature of concrete analysis part and technical requirement, according to the quality of product, production lot, economy, and the situation such as appointed condition selects suitable processing method, customize out economical, advanced, rational technical process, also need the clamp for machining adapting to various processing conditions simultaneously.
Utility model content
It is simply exquisite that technical problem to be solved in the utility model is to provide a kind of structure, is suitable for the clamping apparatus for gear wheel processing to gear retrofit within the scope of 0.05-1.25mm, to solve the above-mentioned multinomial defect caused in prior art.
For achieving the above object, the utility model provides following technical scheme: a kind of clamping apparatus for gear wheel processing, by rigid central spindle, can be risen mandrel, extension spring, location flat key, gear, back-moving spring, plain washer and binding nut composition, in rigid central spindle, cover has the mandrel that can rise, can rise on mandrel and be designed with two annular grooves, two extension springs are embedded in groove respectively, be enclosed within and can rise on mandrel, rigid central spindle and can rise between mandrel and be provided with location flat key, the end of location flat key is fixed on the tail end of the mandrel that can rise, the head end of location flat key is arranged on back-moving spring, back-moving spring is arranged on rigid central spindle and can rises in the head gap of mandrel, the part that rigidity mandrel is exposed at the mandrel exterior that can rise first puts plain washer, install binding nut again to fix, geared sleeve can rise on mandrel.
Preferably, the surface design of described rigid central spindle has ripple glaze.
Preferably, described plain washer is spheric washer.
Preferably, described extension spring, all inlays two extension spring in the annular groove of mandrel that can rise.
Preferably, described back-moving spring designs for dual spring.
The beneficial effect of above technical scheme is adopted to be: the surface design of rigid central spindle has ripple glaze, such design is when mandrel expansion of can rising applies identical power, rigid central spindle reduces due to the ripple glaze contact area on surface, thus increases rigid central spindle applies power sensitivity to the mandrel that can rise; Plain washer is spheric washer, and such design prevents to the damage that fixture itself produces in Gear Processing process, uniform force when simultaneously fixture can be made to step up; Two extension spring is all inlayed in extension spring in the annular groove of mandrel that can rise, and fixture can shrink by such design when very fast; Back-moving spring designs for dual spring, and the design of dual spring alleviates spring fatigue strength in use greatly, and original size of reduction fixture that can be very fast, extends the service life of fixture simultaneously.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Wherein, 1---rigid central spindle, 2---can rise mandrel, and 3---extension spring, 4---location flat key, 5---gear, 6---back-moving spring, 7---plain washer, 8---binding nut.
Detailed description of the invention
Preferred embodiment of the present utility model is described in detail below in conjunction with accompanying drawing.
Fig. 1 shows the detailed description of the invention of a kind of clamping apparatus for gear wheel processing of the utility model: a kind of clamping apparatus for gear wheel processing, by rigid central spindle 1, can be risen mandrel 2, extension spring 3, location flat key 4, gear 5, back-moving spring 6, plain washer 7 and binding nut 8 form, in rigid central spindle 1, cover has the mandrel 2 that can rise, the surface design of rigid central spindle 1 has ripple glaze, such design is when mandrel 2 expansion of can rising applies identical power, rigid central spindle 1 reduces due to the ripple glaze contact area on surface, thus increase rigid central spindle applies power sensitivity to the mandrel 2 that can rise, can rise on mandrel 2 and be designed with two annular grooves, two extension springs 3 are embedded in groove respectively, two extension spring is all inlayed in extension spring 3 in the annular groove of mandrel 2 that can rise, fixture can shrink by such design when very fast, be enclosed within and can rise on mandrel 2, rigid central spindle 1 and can rise to be provided with between mandrel 2 and locate flat key 4, the end of location flat key 4 is fixed on the tail end of the mandrel 2 that can rise, the head end of location flat key 4 is arranged on back-moving spring 6, back-moving spring 6 is arranged on rigid central spindle 1 and can rises in the head gap of mandrel 2, back-moving spring 6 designs for dual spring, the design of dual spring alleviates spring fatigue strength in use greatly, original size of reduction fixture that can be very fast, extend the service life of fixture simultaneously, the part that rigidity mandrel 1 is exposed at mandrel 2 outside of can rising first puts plain washer 7, plain washer 7 is spheric washer, such design prevents in Gear Processing process the damage that fixture itself produces, uniform force when simultaneously fixture can be made to step up, install binding nut 8 again to fix, gear 5 is enclosed within and can rises on mandrel 2.
Above-described is only preferred embodiment of the present utility model; it should be pointed out that for the person of ordinary skill of the art, under the prerequisite not departing from the utility model creation design; can also make some distortion and improvement, these all belong to protection domain of the present utility model.
