Abstract

The utility model discloses a tool shank with high degree of balance, which comprises a cutter body and key slots formed on two sides of the cutter body, wherein the cutter body adopts a hollow tapered structure; the key slots on the two sides of the cutter body have inconsistent sizes and dimensions; and the tool shank with the high degree of balance is characterized in that pre-balanced holes are formed in the key slots; and the cross section areas of the pre-balanced holes are smaller than the cross section areas of the key slots. The tool shank with the high degree of balance has the advantages of simple and reasonable structure, attractive appearance, convenient processing, good safety and reliability and the like; and particularly, the degree of balance of the tool shank can be improved, the processing is more steady, the quality of the processing surface is improved, and the abrasion of a cutting tool is reduced.

Description

A kind of high degree of balance handle of a knife

Technical field

The utility model relates to the machining tool field, is specifically related to a kind of high degree of balance handle of a knife.

Background technology

For a long time, all be one of indispensable cutter at field of machining CAT handle of a knife.At present, the CAT handle of a knife is widely used in field of machining, and its head can connect the multiple interfaces form, as the side-strengthened handle of a knife, and collet handle of a knife, powerful chuck handle of a knife, pyrocondensation handle of a knife, face milling cutters handle of a knife, drill chuck holder, Mohs handle of a knife etc.

For transmitting moment of torsion, usually offer two keyways on the CAT handle of a knife, but because both sides keyway size is asymmetric, make handle of a knife produce a bigger amount of unbalance in working order down, with CAT40 is example, the amount of unbalance that fluting produces is described: the handle of a knife quality is 860g, amount of unbalance 5g, uneven radius r: 23.81mm.In High-speed machining,, even produce potential safety hazard because the asymmetric amount of unbalance that causes of keyway size can cause the crudy instability.

This patent is exactly a kind of new solution that proposes at the problems referred to above.

The utility model content

Technical problem to be solved in the utility model is: how a kind of high degree of balance handle of a knife is provided, that this high degree of balance handle of a knife has is simple and reasonable, appearance looks elegant, easy to process, advantage such as security reliability is good, the more important thing is, can improve the degree of balance of handle of a knife, make processing more steady, improve machined surface quality, reduce tool wear.

For achieving the above object, the technical scheme that the utility model adopted is: a kind of high degree of balance handle of a knife is provided, comprises cutter hub and the keyway that is arranged on the cutter hub both sides; Described cutter hub is the pyramidal structure of hollow; The keyway size dimension of described cutter hub both sides is inconsistent; It is characterized in that: be provided with the pre-equilibration hole in the described keyway; The cross-sectional area in described pre-equilibration hole is less than the cross-sectional area of keyway.

According to high degree of balance handle of a knife provided by the utility model, it is characterized in that: described pre-equilibration hole is provided with one at least.

According to high degree of balance handle of a knife provided by the utility model, it is characterized in that: described pre-equilibration hole is a cylindrical structural.

According to technique scheme as can be known, a kind of high degree of balance handle of a knife provided by the utility model is compared with traditional handle of a knife and is had following advantage: 1, simple and reasonable, appearance looks elegant, easy to process, security reliability good; 2, can improve the degree of balance of handle of a knife, make processing more steady, improve machined surface quality, reduce tool wear.

Description of drawings

The front view of the high degree of balance handle of a knife that Fig. 1 provides for the utility model.

The right view of the high degree of balance handle of a knife that Fig. 2 provides for the utility model.

The partial top view of the high degree of balance handle of a knife that Fig. 3 provides for the utility model.

Wherein, 1, cutter hub; 2, keyway; 3, pre-equilibration hole.

The specific embodiment

Below in conjunction with accompanying drawing the utility model is further described:

As shown in the figure, this high degree of balance handle of a knife comprises cutter hub 1 and the keyway 2 that is arranged on cutter hub 1 both sides; Described cutter hub 1 is the pyramidal structure of hollow; Keyway 2 size dimensions of described cutter hub 1 both sides are inconsistent; It is characterized in that: be provided with pre-equilibration hole 3 in the described keyway 2; The cross-sectional area in described pre-equilibration hole 3 is less than the cross-sectional area of keyway 2.

Described pre-equilibration hole 3 is provided with one at least; Described pre-equilibration hole 3 is a cylindrical structural.

This high degree of balance handle of a knife is removed certain quality in the method that the symmetric position employing symmetry of amount of unbalance is punched, to eliminate the amount of unbalance of handle of a knife integral body according to the static balance principle.This method is not only easy to operate, and allowance can be good at control, and is applicable to the raising of the degree of balance of multiple handle of a knife.

But; the above only is a preferred implementation of the present utility model; should be understood that; for those skilled in the art; under the prerequisite that does not break away from the utility model principle; can also carry out some improvement and modification to the utility model, these improvement and modification also fall in the protection domain of the utility model claim.

Claims
