Pressing plate has the through hole coaxial with it, lower surface is provided with paw, and it is placed in the top of body;
Pull bar comprises fixed cell and bar portion;
Bar portion is socketed in pressing plate and body successively, upper end and fixed cell compact siro spinning technology, and lower end is fixedly connected with pull unit;
Fixed cell is placed on pressing plate upper surface.
Further, inner core sleeve outer cover is connected to spring; The inside radius of spring is less than the radius of tapered inner core lower surface, and length is greater than the height of inner core sleeve, and its lower end is fixed on the upper surface of fixed disk.
Further, the fixedly sleeved flexible back-up ring in upper end, side of socket inner core, the height of cone cored structure is less than the height of socket inner core.
Further, fixed disk is provided with pallet, and pallet has and the through hole being socketed the coaxial and cross-sectional area of inner core and being greater than tapered inner core lower surface area, the height of pallet is less than the height of socket inner core.
Further, pressing plate lower surface is provided with several paws around its edge.
Further, bar portion has attacked screw thread in upper end, and fixed cell is the nut matched with bar portion, and fixed cell cross-sectional area is greater than the cross-sectional area of through hole on pressing plate.
Further, fixed cell comprises the fixed block that a cylinder and three are distributed in cylindrical sides, and the through hole on pressing plate and fixed cell match.
The advantage that the invention has and good effect are: by arranging removable cone cored structure, achieve that workpiece and tapered inner core gaplessly coordinate, workpiece loading and unloading is convenient, reduce hole sliding injury in workpiece, substantially increases the making precision of workpiece external tooth.

Detailed description of the invention
As shown in Figure 1, a kind of synchronized gear shaping clamping tool, comprises body 1, cone cored structure 4, pressing plate 5, pull bar 6;
Body 1 comprises fixed disk 11 and socket inner core 12, body 1 has the through hole coaxial with being socketed inner core 12;
Socket inner core 12 is fixed on the upper surface of fixed disk 11, and coaxial with fixed disk 11;
Cone cored structure 4 comprises tapered inner core 41 and inner core sleeve 42, it has the through hole coaxial with boring cored structure 4, and is socketed on socket inner core 12 by this through hole;
Tapered inner core 41 is cone, and upper surface area is less than lower surface area, and is fixed on inner core sleeve 42 upper surface coaxial with it;
Pressing plate 5 has the through hole coaxial with it, and lower surface is provided with paw 51, and it is placed in the top of body 1;
Pull bar 6 comprises fixed cell 61 and bar portion 62;
Bar portion 62 is socketed in pressing plate 5 and body 1 successively, upper end and fixed cell 61 compact siro spinning technology, and lower end is fixedly connected with pull unit;
Fixed cell 61 is placed on pressing plate 5 upper surface.
Inner core sleeve 42 outer cover is connected to spring 3; The inside radius of spring 3 is less than the radius of tapered inner core 41 lower surface, and length is greater than the height of inner core sleeve 42, and its lower end is fixed on the upper surface of fixed disk 11.
The fixedly sleeved flexible back-up ring 7 in upper end, side of socket inner core 12, the height of cone cored structure 4 is less than the height of socket inner core 12.
Fixed disk 11 is provided with pallet 2, and pallet 2 has and the through hole being socketed the coaxial and cross-sectional area of inner core 12 and being greater than tapered inner core 41 lower surface area, the height of pallet 2 is less than the height of socket inner core 12.
Pressing plate 5 lower surface is provided with several paws 51 around its edge.
As shown in Figure 2, bar portion 62 has attacked screw thread in upper end, and fixed cell 61 is the nut matched with bar portion 62, and fixed cell 61 cross-sectional area is greater than the cross-sectional area of through hole on pressing plate 5.
As shown in Figure 3, fixed cell 61 comprises the fixed block 63 that a cylinder and three are distributed in cylindrical sides, and the through hole on pressing plate 5 and fixed cell 61 match.
Getting workpiece 8 horizontal is inserted on tapered inner core 41, and tapered inner core 41 upper surface radius is less than workpiece 8 internal bore radius, and workpiece 8 can be inserted in very smoothly.Because tapered inner core 41 cross sectional radius increases gradually, when workpiece 8 slips down to the tapered inner core 41 section radius position identical with workpiece 8 internal bore radius, workpiece 8 stops gliding.At this moment workpiece 8 and tapered inner core 41 achieve the blind-mate of radial orientation, and namely both overlap.Now also there is certain distance in workpiece 8 lower surface and pallet 2.Fixed cell 61 side is evenly equipped with three fixed blocks 63, is socketed in outside bar portion 62 from top to bottom, is then rotated to an angle pressing plate by pressing plate 5 through fixed cell 61.Pull bar 6 moves downward under the control of pull unit, and fixed cell 61 is placed on pressing plate 5 upper surface all the time, and band dynamic pressure plate 5 and workpiece 8 move downward, and Compress Spring 3, workpiece 8 lower surface contacts with the upper surface of pallet 2.Thus, the paw 51 on pressing plate 5 and tapered inner core 4 clamping work pieces 8, pallet 2 limits pressing plate to be continued to move downward, and circlip 7 limits the rebound motion of spring 3.This kind of scheme lower tray 2 increases with the contact area of workpiece 8 with the design of pressing plate 5 end face as far as possible, and reduce concentrating of stress with this, workpiece 8 and tapered inner core 41 can realize again the blind-mate in radial direction, and these are beneficial to the machining accuracy improving workpiece.
Above the embodiment of the invention has been described in detail, but described content being only the preferred embodiment of the invention, can not being considered to for limiting practical range of the present invention.All equalizations done according to the invention scope change and improve, and all should still belong within this patent covering scope.
