Abstract
The utility model discloses a fixture special for machining a single-key gear. A first through hole is formed in the center of a base sleeve. The base sleeve comprises a lathe connecting part and a tool connecting part. A boss is arranged in the center of the tool connecting part. The boss is in clearance fit with a second through hole. A connecting plate is fixedly connected with the base sleeve through a first bolt. A third through hole concentric with the second through hole is formed in the center of a supporting plate. One end of the supporting plate is provided with a disc-shaped supporting part. The other end of the supporting plate is provided with a fixing part which is in a cone shape. A threaded hole is formed in the fixing part in the radial direction. The supporting plate and the connecting plate are fixedly connected through a second bolt. A central spindle is formed in the third through hole in a clearance fit mode. The outer surface of the central spindle is provided with a single key. A fourth through hole concentric with the third through hole is formed in the center of the central spindle. The fitting surface between the central spindle and the third through hole is a cylindrical surface. The fixture special for machining the single-key gear is used for machining multiple models of single-key gears, so that universality of the fixture for the single-key gears is improved.
Description
Technical field
The utility model relates to a kind of special fixture, specifically, particularly relates to a kind of for clamping the special fixture of singly-bound gear.
Background technology
Singly-bound gear fixture is in the market structure as a whole, and add man-hour to the singly-bound gear of different model, just must be along with whole singly-bound gear special fixture is changed together.
Along with the demand in market, the kind of singly-bound gear is more and more, so the replacing of singly-bound 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 singly-bound gear special fixture of singly-bound 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 singly-bound gear of a kind of versatility special fixture.
For achieving the above object, the utility model provides a kind of processing singly-bound 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 outer surface of described mandrel is set to singly-bound, and 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 singly-bound gear, has improved the versatility of singly-bound 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 singly-bound gear of processing multiple types, have improved the versatility of singly-bound gear fixture.
Accompanying drawing explanation
Fig. 1 is the utility model concrete structure schematic diagram.
The specific embodiment
Below in conjunction with drawings and Examples, the utility model is described in further detail:
As shown in Figure 1, a kind of processing singly-bound 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 outer surface of described mandrel 8 is set to singly-bound 8a, and 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, the keyway of bore is coordinated with the singly-bound of 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.
