Abstract
The utility model belongs to gear machining technology field, particularly relate to a kind of gear-hobbing clamp of fast changeable, comprise and fix gear hobbing base on the table by hold-down screw, it is characterized in that being fixed with gear hobbing mandrel dish by soket head cap screw above described gear hobbing base, be provided with gear hobbing underlay above described gear hobbing mandrel dish, by described gear hobbing mandrel dish, gear hobbing mandrel be fixed on gear hobbing base.Gear-hobbing clamp of the present utility model, changes into " the taper shank connection " of prior art " cylindrical hole and end face are located by connecting ", reaches the object directly changing gear hobbing mandrel, its structure is simple, stable performance, and cost is extremely low, reduce labour intensity, greatly improve and change efficiency.
Description
Technical field
The utility model belongs to gear machining technology field, particularly relates to a kind of gear-hobbing clamp of fast changeable.
Background technology
Gear hobbing process is an of paramount importance link in Gear Processing process, and gear-hobbing clamp is that in gear hobbing process, workpiece connects with lathe and ensures the basis of machining accuracy, and therefore change workpiece to be processed kind all needs to change fixture at every turn.Along with the popularization of the Flexible Production theory of multi items, small lot, the replacing of frock clamp becomes very frequent.As shown in Figure 1, the replacing options of existing gear-hobbing clamp is: first pulled down from gear hobbing workbench by gear hobbing base, after then taking nut apart with special spanner, changes gear hobbing underlay and gear hobbing mandrel.The shortcoming of this method is: 1, gear hobbing base is very heavy, and all gear hobbing base will be dismantled, labour intensity is excessive at every turn, and easily produces to collide with etc. and cause frock installation accuracy misalignment; 2, after gear hobbing base is pulled down, radial reference for installation destroys completely, needs centering gear-hobbing clamp again, causes gear-hobbing clamp to change efficiency extremely low; 3, gear-hobbing clamp adopts taper shank connected mode, and difficulty of processing is large, and cost is high.
Utility model content
The deficiency that the utility model exists for above-mentioned prior art, provide a kind of structure simple, change quick and lower-cost gear-hobbing clamp.
The technical scheme that the utility model solves the problems of the technologies described above is as follows: a kind of gear-hobbing clamp of fast changeable, comprise and fix gear hobbing base on the table by hold-down screw, its special character is to be fixed with gear hobbing mandrel dish by soket head cap screw above described gear hobbing base, is fixed on gear hobbing base by gear hobbing mandrel by described gear hobbing mandrel dish.
Further, gear hobbing underlay is provided with above described gear hobbing mandrel dish.
The beneficial effect of above-mentioned further scheme is adopted to be that gear hobbing underlay plays the effect of axial support workpiece.
The beneficial effects of the utility model are: gear-hobbing clamp of the present utility model, " the taper shank connection " of prior art is changed into " cylindrical hole and end face are located by connecting ", reach the object directly changing gear hobbing mandrel, its structure is simple, stable performance, cost is extremely low, reduces labour intensity, greatly improves and changes efficiency.
Accompanying drawing explanation
Fig. 1 is the structural representation of existing gear-hobbing clamp;
Fig. 2 is structural representation of the present utility model;
In figure, 1, gear hobbing base; 2, nut; 2 ', soket head cap screw; 3, gear hobbing mandrel; 4, gear hobbing underlay; 5, hold-down screw; 6, gear hobbing mandrel dish.
Detailed description of the invention
Be described principle of the present utility model and feature below in conjunction with accompanying drawing, example, only for explaining the utility model, is not intended to limit scope of the present utility model.
A kind of gear-hobbing clamp of fast changeable, comprise by the fixing gear hobbing base 1 on the table of hold-down screw 5, its special character is to be fixed with gear hobbing mandrel dish 6 by soket head cap screw 2 ' above described gear hobbing base 1, be provided with gear hobbing underlay 4 above described gear hobbing mandrel dish 6, by described gear hobbing mandrel dish 6, gear hobbing mandrel 3 be fixed on gear hobbing base 1.
The utility model is installed and used like this, when installing first, by gear hobbing base 1 fine finishining, the depth of parallelism of guarantee upper and lower end face and locating hole are to the perpendicularity of lower surface, ensure the precision of gear hobbing mandrel 3, its each contact surface beated and is less than 0.005mm, then by gear hobbing base 1 by gear hobbing mandrel dish 6, soket head cap screw 2 ' and gear hobbing underlay 4 and gear hobbing mandrel 3 install fix after refill and clip on workbench, centering gear hobbing mandrel 3, installation and debugging complete.In use, changing workpiece to be processed at every turn, directly changing gear hobbing mandrel 3, without the need to being pulled down by gear hobbing base 1.
More than for the utility model for embodiment, only establish for ease of explanation, when meaning of the present utility model can not be limited with this, namely generally according to the various shift design that the application's the scope of the claims is done, all should be included in the scope of the claims of the present utility model.
Claims (2)
