Abstract
The utility model discloses a spring clamping head knife handle with an eccentric locking nut balance structure. The spring clamping head knife handle comprises a knife handle main body whose one end is connected with the main shaft of a processing center machine tool, wherein other end thereof is clamped by a locking nut with an eccentric hole and is provided with a cutter, the outer periphery of the locking nut is provided with a plurality of spanner grooves for balancing the gravity center of the locking nut, and the spanner groove comprises a small spanner groove and a big spanner groove with different specifications and sizes. A clamping cutter and a ring-shaped circlip which generates retracting and expanding function are arranged between the locking nut and the cutter, and a screw which limits the cutter to axially recede is further arranged on the position inside the knife handle main body close to the cutter. The spring clamping head knife handle has simple structure, excellently solves the balance problem of the locking nut through the improvement of the structure, guarantees the excellent processing precision of the knife handle when the knife handle rotates at high speed of 8000-120000, and simultaneously effectively protects the precision and the service span of the main shaft of the machine tool.
Description
Technical field
The utility model belongs to field of machining, specifically relates to a kind of collet handle of a knife with Camlock nut balanced structure.
Background technology
Many weeks, when on machining handle of a knife work in-process scheming bed, using, its rotating speed is high more, just require the balance of handle of a knife parts high more, otherwise can be because the imbalance of handle of a knife makes machine tool spindles produce vibrations, thereby reduce main shaft precision and machining accuracy, even shorten the service life of machine tool chief axis.
Yet at present the collet handle of a knife that uses mainly is to be made of with the holder main body that the machining center machine tool chief axis is connected an end, and the other end of holder main body is by the cutter that has been fixedly clamped of the locking nut with eccentric orfice.The handle of a knife of this structure, because of the eccentric orfice that has on its locking nut is to reach the purpose of being convenient in use utilize the cutter after eccentric orfice will clamp to take out of together with locking nut, this just structure has brought disequilibrium for this body structure of locking nut, so in the process of companion handle of a knife rotation, cause handle of a knife the problem of disequilibrium, precision and the machining accuracy and the service life of directly damaging the machining center machine tool chief axis also can occur.
The utility model content
The purpose of this utility model is to address the above problem, and a kind of simple in structure, collet handle of a knife with Camlock nut balanced structure that balance is good is provided.
For reaching the foregoing invention purpose, the technical scheme that is adopted is: the collet handle of a knife with Camlock nut balanced structure, comprise the holder main body that an end is connected with the machining center machine tool chief axis, the other end of holder main body is by the cutter that has been fixedly clamped of the locking nut with eccentric orfice, the outer circumference of described locking nut is provided with the spanner groove of a plurality of counter lock jack panel centers of gravity, and described spanner groove is made of specification small wrench groove and big spanner groove inequality.
The quantity of described spanner groove is six, wherein four undersized small wrench grooves are arranged at the side away from the locking nut center of gravity, two other large-sized big spanner groove is arranged at the side near the locking nut center of gravity, and six spanner grooves are equally spaced and are arranged on the locking nut excircle.
Be provided with clamp-on tool between described locking nut and the cutter and produce the annular jump ring that shrinks the expansion effect.
The position of next-door neighbour's cutter also is provided with the screw that the restriction cutter shaft is drawn back in the described holder main body.
In sum; the utility model is simple in structure, by the improvement of said structure, has solved locking nut balance problem well; ensure handle of a knife good machining accuracy when 8000～12000 high rotating speeds that change use, effectively protected machine tool chief axis precision and service life simultaneously.

Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the broken section structural representation of locking nut;
Fig. 3 is the broken section structural representation of locking nut left side apparent direction among Fig. 2;
Fig. 4 is the local structure for amplifying schematic diagram of locking nut upper ejector lever groove position;
Among the figure: 1-holder main body, 2-screw, 3-locking nut, 4-jump ring, 5-cutter, 6-spanner groove, 6.1-small wrench groove, the big spanner groove of 6.2-, B-sidewall length, L-parallel-segment length, the H-degree of depth.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described in further detail:
Shown in Fig. 1～3, collet handle of a knife with Camlock nut balanced structure, comprise the holder main body 1 that an end is connected with the machining center machine tool chief axis, the other end of holder main body 1 is by the cutter 5 that has been fixedly clamped of the locking nut 3 with eccentric orfice, the outer circumference of described locking nut 3 is provided with the spanner groove 6 of a plurality of counter lock jack panel 3 centers of gravity, and described spanner groove 6 is made of specification small wrench groove 6.1 and big spanner groove 6.2 inequality.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 centers of gravity, two other large-sized big spanner groove 6.2 is arranged at the side near locking nut 3 centers of gravity, and six spanner grooves 6 are equally spaced and are arranged on locking nut 3 excircles.Be provided with clamp-on tool 5 between locking nut 3 and the cutter 5 and produce the annular jump ring 4 that shrinks the expansion effect, the position of next-door neighbour's cutter 5 also is provided with the screw 2 that restriction cutter 5 axially retreats in the holder main body 1.
As shown in Figure 4, in the specific implementation, the locking nut sidewall length B on small wrench groove 6.1 sides is greater than the sidewall length of big spanner groove 6.2, and all less than the parallel-segment length and the degree of depth of big spanner groove 6.2, table one specifically sees the following form for the parallel-segment length L of small wrench groove 6.1 and depth H.
| L±0.05(mm) | B±0.05(mm) | H±0.05(mm) | |
| The small wrench groove | 9.00 | 5.67 | 2.50 |
| Big spanner groove | 9.36 | 5.67 | 2.85 |
The number range that the utility model is not limited in the foregoing description to be exemplified can be according to the different accommodation of carrying out of handle of a knife and locking nut specification size in the actual processing.
