Laminating, the end that the cammed surface is located in waist-shaped hole with the taper shank is pushed against, and the threaded rod is protruded out to outside waist-shaped hole, institute
Nut is stated to be connect with the aperture gear of waist-shaped hole.
Preferably, the drive block includes tapered wedges and wedge block, with taper shank end phase on the wedge block
To side offer a slot, the depth direction of the slot is vertical with the axis of the semi-cylindrical side, the tapered wedges
It is slidably arranged in slot, and the cammed surface of tapered wedges is protruded out on the outside of the notch of slot, is offered on the semicircle side
Parallel to tapered wedges glide direction and the screwed hole in slot is through to, is provided with the screwed hole and is protruded out for adjusting tapered wedges
The jackscrew of distance.
Preferably, the nut is provided with the handle being radially arranged.
Preferably, the handle passes through to be welded to connect with nut.
Preferably, it is provided with packing ring between the nut and waist-shaped hole aperture.
Preferably, one end that the packing ring fits with the outer ring surface of taper shank connecting rod is the outer ring surface with taper shank connecting rod
Isometrical arc surface, packing ring is plane with one end that nut fits.
The technical effects of the invention are that：, without impulsive force, dismounting is steady, and safety labor-saving can be according to not for this extracting tool
With the overhang of the adjustment wedge of gap length, this instrument does not allow wedge-shaped block directly to be contacted with taper-shank cutter, but
Allow single wedge to be above in contact with it, worn and torn it is rear directly change wedge, and without changing entirety, reduce use cost；
The outer-hexagonal nut of welding handle can be pulled easily with hand, easy to use without being pulled spanner is looked for.
Brief description of the drawings
Fig. 1 is the structural representation of taper shank link；
Fig. 2 is the sectional view of taper shank extracting tool use state of the invention；
Fig. 3 is the dimensional structure diagram of drive block of the invention.
Specific embodiment
The present invention is described in detail below in conjunction with accompanying drawing.
As shown in Figure 1, 2, 3, the extracting tool of a kind of taper shank 5, including a tabular drive block, the drive block has half
Cylindrical side 41, and the cammed surface 42 set with 41 one-tenth of semi-cylindrical side angle；The semi-cylindrical side 41 with
The mutually close one end of cammed surface 42 is extended a threaded rod 43, the axis of the threaded rod 43 and the axle of semi-cylindrical side 41
Line is parallel；Also include constituting the nut 3 that screw thread coordinates with the threaded rod 43；During dismounting taper shank 5, the drive block is interspersed in
In waist-shaped hole 11 in taper shank connecting rod 1, wherein the semi-cylindrical side 41 and the interior one end away from taper shank 5 of waist-shaped hole 11
Arc surface is fitted, and the end that the cammed surface 42 is located in waist-shaped hole 11 with the taper shank 5 is pushed against, and the threaded rod 43 is protruded out to
Outside waist-shaped hole 11, the nut 3 connects with the aperture gear of waist-shaped hole 11., without impulsive force, dismounting is steady, and safety is saved for this extracting tool
Power.This provision for disengagement is fitted by semi-cylindrical with the semicircular inner walls of waist-shaped hole 11, and dismounting is produced using the binding face
The reaction force of taper shank 5, its contact area is big, and unit area pressure is smaller, is difficult that the inwall of waist-shaped hole 11 is caused to damage.
Preferably, the drive block includes tapered wedges 7 and wedge block 4, with the end of the taper shank 5 on the wedge block 4
The relative side in portion offers a slot, and the depth direction of the slot is vertical with the axis of the semi-cylindrical side 41, described
Tapered wedges 7 are slidably arranged in slot, and the cammed surface 42 of tapered wedges 7 is protruded out on the outside of the notch of slot, the semicircle side
Offered on side parallel to the glide direction of tapered wedges 7 and the screwed hole 6 that is through in slot, be provided with the screwed hole 6 for
Regulation tapered wedges 7 protrude out the jackscrew of distance.Can be according to the overhang of the adjustment wedge of different gap size, this instrument is not
Allow wedge-shaped block directly with the tool contact of taper shank 5, but allow single wedge to be above in contact with it, worn and torn and rear directly changed
Wedge, and without changing entirety, reduce use cost.
The nut 3 is provided with the handle being radially arranged, and the handle is with nut 3 by being welded to connect.Welding handle
Outer-hexagonal nut 3 easily can be pulled with hand, it is easy to use without being pulled spanner is looked for.
It is provided with packing ring 2 between the nut 3 and the aperture of waist-shaped hole 11, the outer ring surface phase of the packing ring 2 and taper shank connecting rod 1
One end of laminating is the arc surface isometrical with the outer ring surface of taper shank connecting rod 1, and packing ring 2 is plane with one end that nut 3 fits.
Packing ring 2 can avoid the outer ring surface directly contact of nut 3 and taper shank connecting rod 1, and then avoid damaging cone in the rotary course of nut 3
The outer ring surface of handle connecting rod 1.
Presently preferred embodiments of the present invention is the foregoing is only, is not intended to limit the invention, it is all in essence of the invention
