The Outer Taper correspondence of described taper hole axle left end loads in workpiece taper hole, and described locating piece is band step fan shape structure, locating piece is provided with the groove corresponding with excircle of workpiece flange, realizes clamping the location of workpiece.
Described push rod is three.
Be provided with T-shaped key in described fixed disk center taper hole, be also provided with broaching tool backing plate in described taper hole axle endoporus, on described locating piece, correspondence is provided with pin, and pin comprises straight pin and chamfered edge pin.
The beneficial effects of the utility model: described a kind of automatic stocking formula draws taper hole key groove clamp, it is by workpiece and broaching tool normal mounting location, for broaching tool feed stroke provides location condition, and workpiece is provided to exit the power of (automatic material returning) at broaching tool withdrawing stroke.1), simple and compact for structure there is following advantage in it:, and except fixed disk, Workpiece fixing element has axle, locating piece; Broaching tool director element is T-shaped key and backing plate; 2), utilize taper fit, ensure that the axiality of workpiece, cutter and broaching machine, and be installed solid and reliable thus ensure that Workpiece Machining Accuracy is high; 3), by push rod, spring and cushion cover coordinate and realize automatic material returning, easy to operate, enhance productivity.
Accompanying drawing illustrates:
Fig. 1 main TV structure principle schematic of the present utility model;

Shown in figure: 1. taper hole axle; 2. locating piece; 3. hexagon socket head cap screw; 4. fixed disk; 5. spring; 6. push rod; 7. cushion cover; 8. packing ring; 9. spring washer; 10. nut; 11. backing plates; 12. pins; 13.T shape key.
Detailed description of the invention
The utility model is described in detail below in conjunction with accompanying drawing.
As illustrated in fig. 1 and 2, described a kind of automatic stocking formula draws taper hole key groove clamp, be characterized in comprising the fixed disk 4 be arranged on as clamp body on broaching machine center bearing bracket, taper hole axle 1 right-hand member Outer Taper is inserted in the taper hole of fixed disk 4 center, taper hole axle 1 left end is Outer Taper, locating piece 2 is arranged on fixed disk 4 by hexagon socket head cap screw 3, cushion cover 7 is provided with on the right side of fixed disk 4, push rod 6 correspondence is through the cylindrical hole on cushion cover 7 and fixed disk 4, push rod 6 between cushion cover 7 and fixed disk 4 is arranged with spring 5, push rod 6 is by packing ring 8, spring washer 9 and nut 10 are fixedly linked with cushion cover 7.
The Outer Taper correspondence of described taper hole axle 1 left end loads in workpiece taper hole, and described locating piece 2 is band step fan shape structure, locating piece 2 is provided with the groove corresponding with excircle of workpiece flange, realizes clamping the location of workpiece.
Described push rod is three.
Be provided with T-shaped key 13 in described fixed disk 4 center taper hole, be also provided with broaching tool backing plate 11 in described taper hole axle 1 endoporus, on described locating piece 2, correspondence is provided with pin 12, and pin 12 comprises straight pin and chamfered edge pin.
Described a kind of automatic stocking formula draws taper hole key groove clamp, its fixed disk 4 is as the clamp body of this fixture, its inner port edge axially opens a straight trough, correspondingly axially also open same shape straight trough at taper hole axle 1 cylindrical, straight trough width is corresponding with keyway broach nominal width, the straight trough degree of depth and T-slot 13 height, broaching tool height, broaching tool backing plate 11 height correlation; Its seam coordinates with broaching machine center bearing bracket, connects with 4 bolts; Spring 5 is enclosed within push rod 6; A left side for push rod 6, right-hand member inserts in three circular holes of fixed disk 4 and cushion cover 7 respectively; Push rod 6 and cushion cover 7 pass through packing ring 8, spring washer 9, and nut 10 is fixedly connected with, and forms automatic pusher together; Backing plate 11 is placed in bottom taper hole axle 1 straight trough, and its thickness is determined according to broaching tool height and adjusted depending on the broaching tool degree of wear; Pin 12 is as the setting element of locating piece 2, and T-shaped key 13 is as director element, and purposes makes broaching tool alignment pieces, simultaneously through the straight trough on fixed disk 4 and taper hole axle 1.Stroke return by broaching tool, arranged by broaching machine, cushion cover Compress Spring, drives push rod to move to left and to be ejected by workpiece; Simultaneously due to the elastic reaction of spring, push rod rigid shock is avoided to cause part deformation and damage.This class part of processing has center taper hole, and by technical requirement, and in the operation before wire pulling method, to the machining accuracy in hole and the perpendicularity between hole and end face, there are strict requirements.According to the shape facility of this kind of part and the processing request of preposition operation, the utility model adopts axle tapering location fit angle orientation can meet workpiece taper hole key slot center and the requirement of broaching machine carriage center axiality completely, and structure simplification, compact.
