Abstract
The invention discloses a collet chuck handle with an eccentric locknut balance structure; the collet chuck handle comprises a handle body with one end connected with a machining center machine tool main shaft; the other end of the handle body is provided with a cutter fixed and clamped by the locknut having an eccentric hole; the outer periphery of the locknut is provided with a plurality of wrench grooves used for balancing the gravity center of the locknut; the wrench grooves comprise small wrench grooves and big wrench grooves of different specification sizes. An annular jump ring used for clamping the cutter and generating contraction/expansion effects is arranged between the locknut and the cutter; the position, close to the cutter, in the handle body is also provided with a screw used for stopping the cutter from axially going backwards; above all, the collet chuck handle is simple in structure, and the improved structure can well solve the locknut balance problems, thus ensuring the handle to have excellent processing precision at high speed of 8000-12000 turn, and simultaneously effectively protecting the machine tool main shaft precision and service life.
Description
Technical field
The invention belongs to field of machining, in particular to a kind of spring clamping head knife handle with eccentric locking nut balance structure.
Background technology
As is well known, when machining handle of a knife work in-process scheming bed uses, its rotating speed is more high, just require that the balance of shank section part is more high, otherwise machine tool spindles can be made to produce vibrations due to the imbalance of handle of a knife, thus reducing main shaft precision and machining accuracy, even shorten the service life of machine tool chief axis.
But the holder main body that currently used spring clamping head knife handle is mainly connected with processing center machine tool main shaft by one end is constituted, the other end of holder main body has been fixedly clamped cutter by the locking nut with eccentric orfice.The handle of a knife of this structure, eccentric orfice because having on its locking nut is the purpose reaching to be easy in use utilize eccentric orfice to be taken out of together with locking nut by the cutter after clamping, this structure brings disequilibrium to this body structure of locking nut just, so causing handle of a knife also to there will be the problem of disequilibrium in the process rotated in company with handle of a knife, the directly infringement precision of processing center machine tool main shaft and machining accuracy and service life.
Summary of the invention
It is an object of the invention to solve the problems referred to above, it is provided that what a kind of simple in construction, balance were good has the spring clamping head knife handle of eccentric locking nut balance structure.
For foregoing invention purpose can be reached, be the technical scheme is that the spring clamping head knife handle with eccentric locking nut balance structure, including the holder main body that one end is connected with processing center machine tool main shaft, the other end of holder main body has been fixedly clamped cutter by the locking nut with eccentric orfice, the outer circumference of described locking nut is provided with the spanner groove of multiple counter lock jack panel center of gravity, and small wrench groove and big spanner groove that described spanner groove is differed by specification are constituted.
The quantity of described spanner groove is six, wherein four undersized small wrench grooves are arranged at the side away from locking nut center of gravity, two other large-sized big spanner groove is disposed in proximity to the side of locking nut center of gravity, and six spanner grooves are equally spaced and are arranged on locking nut excircle.
It is provided with clamp-on tool between described locking nut and cutter and produces to shrink the annular jump ring of extension effect.
In described holder main body, the position of next-door neighbour's cutter is additionally provided with the screw that restriction cutter shaft is drawn back.
In sum; present configuration is simple, by the improvement of said structure, solves locking nut balance problem well; ensure the machining accuracy that handle of a knife is good when the high rotating speed of 8000～12000 turns uses, effectively protect machine tool chief axis precision and service life simultaneously.

Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention is described in further detail:
As shown in Figures 1 to 3, there is the spring clamping head knife handle of eccentric locking nut balance structure, including the holder main body 1 that one end is connected with processing center machine tool main shaft, the other end of holder main body 1 has been fixedly clamped cutter 5 by the locking nut 3 with eccentric orfice, the outer circumference of described locking nut 3 is provided with the spanner groove 6 of multiple counter lock jack panel 3 center of gravity, and small wrench groove 6.1 and big spanner groove 6.2 that described spanner groove 6 is differed by specification are constituted.The quantity of described spanner groove 6 is six, wherein four undersized small wrench grooves 6.1 are arranged at the side away from locking nut 3 center of gravity, two other large-sized big spanner groove 6.2 is disposed in proximity to the side of locking nut 3 center of gravity, and six spanner grooves 6 are equally spaced and are arranged on locking nut 3 excircle.Being provided with clamp-on tool 5 between locking nut 3 and cutter 5 and produce to shrink the annular jump ring 4 of extension effect, in holder main body 1, the position of next-door neighbour's cutter 5 is additionally provided with the screw 2 that restriction cutter 5 axially retreats.
As shown in Figure 4, in the specific implementation, the locking nut side wall length B on small wrench groove 6.1 side is more than the side wall length of big spanner groove 6.2, and the parallel-segment length L of small wrench groove 6.1 and depth H are respectively less than parallel-segment length and the degree of depth of big spanner groove 6.2, are specifically shown in following table table one.
It is emphasized that, it is above the preferably enforcement row of the present invention, not the present invention is done in appearance any type of restriction, every any simple modification, equivalent variations and modification above example made according to the technical spirit of the present invention, all still falls within the scope of technical solution of the present invention.
