Detailed description of the invention
Concrete structure of the present utility model is described in detail according to Fig. 1～8.This taper shank set includes by the cylinder being arranged on one end
Section 6, the adpting flange 7 at middle part and be arranged on the taper shank set main body 1 that the cone segments 8 of the other end is formed, be arranged on taper shank set
Collet 2 within main body 1 one end and be used for fastening the locking nut 3 of collet 2, wherein taper shank set main body 1 one end
Column body segment 6 is designed as hollow structure, and column body segment 6 front portion is provided with the external screw thread 4 for coordinating, and cylinder with locking nut 3
The front portion of the cavity 9 of section 6 hollow structures is designed with the collet matched with collet 2 and coordinates inclined-plane 10.Taper shank set is main
The keyway 11 coordinated with key on lathe it is provided with and for being installed by screw by adpting flange 7 on adpting flange 7 in the middle part of body 1
Locking hole 12 on lathe.The tapering of the cone segments 8 of taper shank set main body 1 other end is connected the tapering of taper hole and matches with lathe
Close, make whole taper shank set be connected with lathe.
During for the ease of whole taper shank cover locking, the clamping of institute's use spanner, in the column body segment 6 of taper shank set main body 1 one end
The profile in portion is made into the shape of outer-hexagonal 5 by conventional circle.
The dismounting of taper shank set for convenience, the adpting flange 7 in the middle part of taper shank set main body 1 is provided with dismounting internal thread hole
13。
For reducing the sides such as the difficulty of processing of the whole tapering of cone segments 8 of taper shank set main body 1 other end, saving processing cost
The consideration in face, to cone segments 8 central region on the basis of original tapering is constant, has carried out further processing, has made radial ruler
Very little reduction 0.1～0.2mm, makes the radial dimension radial dimension less than 8 liang of end regions of cone segments in this section of region.
In order to match with matching used collet 2, cavity 9 front portion of the column body segment 6 of taper shank set main body 1 one end sets
The collet put coordinates the angle design on inclined-plane 10 to be 16 °.
The collet 2 being arranged in the front cavity 9 of taper shank set main body 1 is that ER32 presss from both sides spring structure.
The taper design of the cone segments 8 of taper shank set main body 1 other end is No. 4 taperings of Mohs, in order to be assemblied in the phase of lathe
In answering the taper hole of tapering.
During use, in the cavity 9 of column body segment 6 front portion that collet 2 is put into taper shank set main body 1, it is ensured that elastic clip
The conical surface of 2 coordinates inclined-plane 10 to contact with the collet of cavity 9 front portion of column body segment 6, then locking nut 3 is pre-installed
On the external screw thread 4 of column body segment 6 front portion of taper shank set main body 1, but need not tighten.The cone segments 8 that taper shank overlaps main body 1 loads
In the corresponding taper hole of machine tool chief axis, make the keyway 11 on the adpting flange 7 of taper shank set main body 1 and the key of setting on machine tool chief axis
In mating connection, and use bolt or locking pin etc. by the locking hole 12 on adpting flange 7, whole taper shank set is connected to machine
On bed main shaft.Select the corresponding cutter that operation existing with workpiece to be processed matches, by the handle of a knife of cutter through locking nut 3 He
The through hole at collet 2 center, is arranged in taper shank set；After Cutting tool installation manner puts in place, tighten locking nut 3, make collet 2
The fully handle of a knife of clamp-on tool, it is ensured that cutter can follow machine tool chief axis and taper shank set rotates.
When workpiece to be processed is according to the processing technique formulated, when needing to change tool sharpening, first unscrew locking nut 3,
Make the handle of a knife of collet 2 loosening cutter, by pulling-out of cutter, then existing operation needs the handle of a knife of the cutter used through lock
Jack panel 3 and the through hole at collet 2 center, tighten locking nut 3, the handle of a knife of collet 2 clamp-on tool, make whole cutter
It is securely mounted in taper shank set, it is achieved quick, not damaged, the nothing of cutter deform installs.
During taper shank set with the whole installation and removal of lathe and cutter and taper shank set, torque wrench can be used to press from both sides
Handle the outer-hexagonal 5 in the middle part of the column body segment 6 of taper shank set main body 1, in order to quickly lock and unscrew.
When needs carry out regularly maintaining to lathe and taper shank set etc., owing to using for a long time, may meet
To the situation of dismounting taper shank set inconvenience, special extracting tool at this moment can be used by the connection method in the middle part of taper shank set main body 1
Whole taper shank set is pulled down by dismounting internal thread hole 13 easily that arrange on blue 7.
Put into the collet 2 in the front cavity 9 of taper shank set main body 1, can be that ER32 presss from both sides spring structure, and permissible
Having water-proof function further, use ER folder spring structure to carry out the handle of a knife of clamping cutter, simple and practical, interchangeability is strong, and accessory is more
Change conveniently.In order to match with matching used ER32 folder spring structure, the cavity 9 of the column body segment 6 of taper shank set main body 1 is anterior to be arranged
Collet coordinate inclined-plane 10 angle design be 16 °.
In order to the taper hole of tapering corresponding to lathe matches, the taper design of the cone segments 8 of taper shank set main body 1 is Mohs cone
Degree, such as: can be Mohs 3, No. 4, No. 5 taperings etc..
