Abstract
The utility model discloses a prevent falling powerful centre gripping handle of a knife of sword relates to the machining tool field, provides the powerful centre gripping handle of a knife that can avoid the sword. Prevent falling powerful centre gripping handle of a knife of sword is provided with the cutter hole and is out of shape the groove including the handle of a knife main part that has centre gripping part and installation parts in the centre gripping part, warp groove slope setting, see to the root by centre gripping part tip, be out of shape groove revolving to being clockwise from inside to outside. Can further be provided with ring channel or helicla flute on the pore wall in cutter hole. The utility model discloses the inhomogeneities that can reduce the centre gripping part wall thickness of handle of a knife with effectively avoid having now powerful centre gripping handle of a knife fall the sword phenomenon.
Description
Technical field
This utility model relates to machine tool field, particularly relates to the brute force clamping handle of a knife of a kind of anti-lost cutter.
Background technology
Existing powerful clamping handle of a knife architecture principle is that holder main body male cone (strobilus masculinus) is coordinated by needle roller with nut inner conical surface, forces holder main body deformation endoporus to shrink during nut, thus clamp-on tool.For making holder main body deformation be more prone to, holder main body endoporus periphery designing axial deformation groove, through research, existing deformation groove has the disadvantage that: 1. deformation wall unevenness is even, and what clamping process needs were bigger screws power, clamps highly difficult；2. axially add holding force deficiency, it is easy to fall cutter (axial displacement of cutter generation sensing workpiece side) phenomenon.
Utility model content
The technical problems to be solved in the utility model is: provide a kind of it can be avoided that fall the brute force clamping handle of a knife of cutter.
The technical scheme is that for solving the problems referred to above the brute force clamping handle of a knife of anti-lost cutter includes the holder main body with retained part and mounting portion, retained part is provided with cutter holes and deformation groove；Deformation groove is obliquely installed；Being seen to root by retained part end, deformation groove rotation direction from inside to outside is clockwise.
Further: the hole wall of cutter holes is provided with cannelure.
Further: the hole wall of cutter holes is provided with helicla flute.
The beneficial effects of the utility model are: can reduce the inhomogeneities of retained part wall thickness of handle of a knife and be prevented effectively from existing powerful clamping handle of a knife fall cutter phenomenon.Especially being applied in the processing of big cutting force, use the probability occurring cutter phenomenon during common powerful clamping handle of a knife relatively big, product percent defective and disqualification rate are higher, use the new construction of this patent application enterprise can be brought bigger business efficiency undoubtedly.

Figure is labeled as: holder main body 1, retained part 2, deformation groove 3, cannelure 4, nut 5, cutter holes 6, sealing mechanism 7, needle roller 8, helicla flute 9.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, this utility model is further illustrated.
The brute force clamping handle of a knife of anti-lost cutter includes the holder main body 1 with retained part 2 and mounting portion, and retained part 2 is provided with cutter holes 6 and deformation groove 3；Deformation groove 3 is obliquely installed；Being seen to root by retained part 2 end, deformation groove 3 rotation direction from inside to outside is clockwise.Retained part 2 be holder main body 1 for clamping the part of cutter, mounting portion is the holder main body 1 part for being connected with lathe.
As shown in Figure 1 to Figure 3, retained part 2 male cone (strobilus masculinus) is coordinated by needle roller 8 powerful clamping handle of a knife confined state with nut 5 internal taper hole, rotates nut 5 during clamping, and nut 5 moves to retained part 2 root and makes retained part 2 deform, and cutter holes 6 reduces；Nut 5 is finally moved to the face laminating with retained part 2 root；Now cutter holes 6 clamp-on tool.The coolant outflow that sealing mechanism 7 is avoided passing through in holder main body 1 can be set.
Deformation groove 3 of the present utility model tilts clockwise certain angle α (angle is different according to the size of cutter holes 6), so can the even property of wall unevenness brought of complementation retained part 2 male cone (strobilus masculinus), make cutter clamping be more prone to.And cutter is subject to reverse power when normal cutting, cutter has one to the component of main shaft side (moving in opposite direction with falling cutter spacing), avoids the appearance of cutter phenomenon to a certain extent.
In order to avoid cutter further, the hole wall of cutter holes 6 is provided with cannelure 4.Cannelure quantity is recommended as two, it is also possible to be other quantity.When so making cutter be clamped, can occur that trace elastic deformation makes self by firmly locking at the sideline place at cannelure 4 two ends, largely avoid the generation of cutter phenomenon.Cannelure 4 also can be replaced helicla flute.
