Description
Technical field
The utility model relates to a kind of spline gear special fixture, specifically, particularly relates to a kind of for clamping the special fixture of spline gear.
Background technology
Spline gear fixture is in the market structure as a whole, and add man-hour to the spline gear of different model, just must be along with whole spline gear special fixture is changed together.
Along with the demand in market, the kind of spline gear is more and more, so the replacing of spline gear fixture is just quite being bothered, and it is better that therefore those skilled in the art are devoted to develop a kind of versatility, is convenient for changing the spline gear special fixture of spline gear.
Utility model content
Because the above-mentioned defect of prior art, technical problem to be solved in the utility model is to provide the good spline gear special fixture of a kind of versatility.
For achieving the above object, the utility model provides a kind of spline gear special fixture, comprises supporting disk, terminal pad and mother set, and the center of described mother set is provided with the first through hole;
Described mother set comprises lathe connecting portion and frock connecting portion, and the center of described frock connecting portion is provided with boss;
The center of described terminal pad is provided with second through hole concentric with described the first through hole, and described boss coordinates with described the second via clearance, and described terminal pad is fixedly connected with by the first bolt with described mother set;
The center of described supporting disk is provided with the third through-hole concentric with the second through hole, and described supporting disk one end is provided with plate-like support, and the other end of described supporting disk is provided with tapered fixed part, and described fixed part has been disposed radially screwed hole; Described supporting disk is fixedly connected with by the second bolt with terminal pad;
Described third through-hole internal clearance is combined with mandrel; The external part of the relatively described supporting disk of mandrel is provided with spline; The center of described mandrel is provided with the fourth hole concentric with described third through-hole; Described supporting disk is fixedly connected with by the 3rd bolt with mandrel, and the mating surface of described mandrel and described third through-hole is the face of cylinder.Mandrel and third through-hole adopt the face of cylinder to coordinate, better positioning core axle, thereby the machining accuracy of raising gear, and also can simplify the processing of mandrel.
By above technical scheme, mandrel is arranged in the through hole of fixed part and is screwed, and has facilitated the replacing of spline gear, has improved the versatility of spline gear fixture.
As preferably, described lathe connecting portion is the frustum of a cone of relatively described frock connecting portion projection.Above structure is convenient to lathe connecting portion and is fixed on lathe.
The beneficial effects of the utility model are: the utility model is applicable to the spline gear of processing multiple types, have improved the versatility of spline gear fixture.
Brief description of the drawings
Fig. 1 is the utility model concrete structure schematic diagram.
Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is described in further detail:
As shown in Figure 1, a kind of spline gear special fixture, comprises supporting disk 1, terminal pad 2 and mother set 3, and the center of described mother set 3 is provided with the first through hole 3d; Described mother set 3 comprises lathe connecting portion 3a and frock connecting portion 3b, and described frock connecting portion 3b center is provided with boss 3c;
As shown in Figure 1, the center of described terminal pad 2 is provided with second through hole 5 concentric with described the first through hole 3d, described boss 3c and described the second through hole 5 matched in clearance, and described terminal pad 2 is fixedly connected with by the first bolt 6 with described mother set 3;
As shown in Figure 1, the center of described supporting disk 1 is provided with the third through-hole 1c concentric with the second through hole 5, described supporting disk 1 one end is provided with plate-like support 1a, and the other end of described supporting disk 1 is provided with tapered fixed part 1b, and described fixed part 1b has been disposed radially screwed hole 1d; Described supporting disk 1 is fixedly connected with by the second bolt 4 with terminal pad 2;
As shown in Figure 1, described third through-hole 1c internal clearance is combined with mandrel 8; The external part 8a of the relatively described supporting disk 1 of mandrel 8 is provided with spline 8b; The center of described mandrel 8 is provided with the fourth hole 8c concentric with described third through-hole 1c; Described supporting disk 1 is fixedly connected with by the 3rd bolt 7 with mandrel 8, and described mandrel 8 is the face of cylinder with the mating surface of described third through-hole 1c.Mandrel adopts the face of cylinder to coordinate with the second through hole, better positioning core axle, thereby the machining accuracy of raising gear, and also can simplify the processing of mandrel.
As shown in Figure 1, described lathe connecting portion 3a is the frustum of a cone of relatively described frock connecting portion 3b projection.
Operation principle of the present utility model is as follows:
When sectional fixture, first make the frustum of a cone of mother set 3 coordinate with lathe (not shown), thereby make mother set 3 can bear certain axial and radial load.Then make terminal pad 2 coordinate with mother set 3, and fixing by the first bolt 6, and supporting disk 1 coordinates with terminal pad 2, and adopts the second bolt 4 to locate.Finally make mandrel 8 coordinate with supporting disk 2, and fixing with the 3rd bolt 7.Gripping sleeve coordinates with telescopic screw rod (not shown) on lathe.
When machining gears, end has the gripping sleeve (not shown) of spring function through bore, by the spline fitted of the keyway of bore and mandrel, then screw rod (not shown) retraction, drive gripping sleeve axially-movable, thereby the laminating of the conical end portion that makes gripping sleeve end face chamfering tightly and bore, the recline gear support portion of supporting disk 2 of the other end of gear.After gear blank fixes, can start gear blank to carry out Milling Process.
If desired, when processing has the gear of another model inner hole key slot, directly change the mandrel matching, and replace whole mother set frock without entirety.
The utility model is only applicable to the processing of endoporus spline gear, for the gear of other inner hole structures, needs other special fixture.
More than describe preferred embodiment of the present utility model in detail.Should be appreciated that those of ordinary skill in the art just can make many modifications and variations according to design of the present utility model without creative work.Therefore, all technical staff in the art comply with design of the present utility model on the basis of existing technology by the available technical scheme of logical analysis, reasoning, or a limited experiment, all should be in by the determined protection domain of claims.
