The technical effects of the invention are that: this extracting tool is without impact force, and disassembly is steady, and safety labor-saving can be according to not
With the overhang of the adjustment wedge block of gap size, this tool does not allow wedge-shaped block directly to contact with taper-shank cutter, but
Allow above individual wedge block be in contact with it, worn it is rear directly change wedge block, and do not have to change entirety, reduce use cost；
The outer-hexagonal nut of welding handle can pull easily with hand, easy to use without pulling looking for spanner.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of taper shank link；
Fig. 2 is the cross-sectional view of taper shank extracting tool use state of the invention；
Fig. 3 is the schematic perspective view of drive block of the invention.
Specific embodiment
The present invention is described in detail below in conjunction with attached drawing.
As shown in Figure 1, 2, 3, a kind of 5 extracting tool of taper shank, the drive block including a plate, the drive block have half
Cylindrical side 41, and the cammed surface 42 being arranged with the semi-cylindrical side 41 at angle；The semi-cylindrical side 41 with
The mutually close one end of cammed surface 42, which is extended, a threaded rod 43, the axis of the threaded rod 43 and the axis of semi-cylindrical side 41
Line is parallel；It further include constituting the nut 3 being threadedly engaged with the threaded rod 43；When dismantling taper shank 5, the drive block is interspersed in cone
In waist-shaped hole 11 in handle connecting rod 1, wherein the circle of one end in the semi-cylindrical side 41 and waist-shaped hole 11 far from taper shank 5
Cambered surface fitting, the cammed surface 42 are located at the abutting of the end in waist-shaped hole 11 with the taper shank 5, and the threaded rod 43 protrudes out to
Outside waist-shaped hole 11, the aperture gear of the nut 3 and waist-shaped hole 11 is connect.For this extracting tool without impact force, disassembly is steady, and safety saves
Power.This provision for disengagement is bonded by semi-cylindrical with the semicircular inner walls of waist-shaped hole 11, and disassembly is generated using the binding face
The reaction force of taper shank 5, contact area is big, and unit area pressure is smaller, is not easy to cause to damage to 11 inner wall of waist-shaped hole.
Preferably, the drive block includes tapered wedges 7 and inclined wedge block 4, on the inclined wedge block 4 with 5 end of taper shank
The opposite 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 protrudes out on the outside of the notch of slot, the semi-cylindrical
The threaded hole 6 for being parallel to 7 glide direction of tapered wedges and being through in slot is opened up on side, is equipped with and is used in the threaded hole 6
The jackscrew of distance is protruded out in adjusting tapered wedges 7.Can be according to the overhang of the adjustment wedge block of different gap size, this tool is simultaneously
Do not allow wedge-shaped block directly with 5 tool contact of taper shank, but allow above individual wedge block be in contact with it, worn it is rear directly
Wedge block is changed, and does not have to change entirety, reduces use cost.
The nut 3 is equipped with the handle being arranged radially, and the handle and nut 3 pass through welded connecting.Welding handle
Outer-hexagonal nut 3 can easily be pulled with hand, it is easy to use without pulling looking for spanner.
