Description

A kind of collet chuck group

Technical field

The utility model relates to collet chuck fields, and in particular to be a kind of collet chuck group that can determine that aligned cutting tool.

Background technique

Since existing collet chuck group includes collet chuck and cutter, collet chuck is equipped with holding holes and multiple profile grooves, the wherein clamping Hole is axially through the collet chuck, and the holding holes are slightly in a circle, and each profile groove is axially formed in the collet chuck, and multiple profile groove Radially equi-angularly space is arranged, and surrounds the holding holes, and multiple profile groove enables the collet chuck in radially generating deformation；It should Cutter is equipped with installing end and processing end, the installing end and is oppositely arranged with the processing end, and the installing end is slightly in a circle；It is intended to assemble The collet chuck and the cutter, after the holding holes of the collet chuck are protruded at the installing end of the cutter, in the collet chuck in radially generating deformation Afterwards, the cutter can be clamped, that is, the collet chuck and the cutter can be assembled.

But since the holding holes run through the collet chuck, user protrudes into the clamping of the collet chuck at the installing end by the cutter Kong Shi, there is no a definite anchor points, and when the cutter being made to be installed in the collet chuck every time, which stretches out the length of the collet chuck It is inconsistent, cause the depth of tool sharpening inconsistent, the length that collet chuck clamps cutter is also inconsistent, and leads to the excessively loose of clamping Or tension.And since the holding holes are slightly rounded, the installing end of the cutter is also slightly rounded, the cutter when to work pieces process, The cutter can be rotated relative to the holding holes, lead to machining accuracy error, therefore, existing collet chuck group really has it that need to be improved Place.

In view of this, the applicant furthers investigate regarding to the issue above, there is this case generation then.

Utility model content

The main purpose of the utility model is to provide a kind of collet chuck groups, and which solve cutter meetings when the processing of traditional collet chuck group The problem of opposite collet chuck group relatively rotates.

In order to achieve the above objectives, the solution of the utility model is:

A kind of collet chuck group, wherein include collet chuck body and cutter, the collet chuck body includes an accommodating space and two A limiting section, the accommodating space is axially through collet chuck body, two facing settings of limiting section, and the limiting section is convex Set on the wall surface of accommodating space, and there is a thrust surface and an at least confined planes, the thrust surface to be formed in limit for the limit The bottom in portion, an at least confined planes are formed in the side of limiting section, and an at least confined planes are adjacent to thrust surface, and with There is at an angle setting between thrust surface；The cutter is detachably arranged in the accommodating space of collet chuck body, and the cutter Equipped with an installing end and multiple abutment faces, the installing end is set to wherein one end of cutter, and the section at the installing end is one Polygon, and setting corresponding with an at least confined planes, multiple abutment faces are formed in the outer of the neighbouring installing end of the cutter At surface, wherein two abutment faces are limited by the thrust surface in collet chuck body.

Further, the limiting section has two confined planes, and two confined planes are formed in the side of limiting section, and two confined planes Interval setting.

Further, the abutment face is inclined-plane.

Further, the section at the installing end is quadrangle, and the cutter is set there are four abutment face.

Further, the collet chuck body is equipped with two effluent troughs and multiple profile grooves, and each effluent trough is along axial recessed in collet chuck sheet Body, and be connected with accommodating space, and two effluent troughs are respectively arranged on the two sides of accommodating space, each effluent trough is equipped with one and goes out The mouth of a river, the water outlet run through set on the bottom surface of effluent trough；Each profile groove is axially formed in collet chuck body, and and accommodating space It is connected, and radially equi-angularly space is arranged multiple profile grooves, two profile grooves therein go out with the two of two effluent troughs respectively The mouth of a river is connected setting.

After adopting the above structure, compared with prior art, the utility model relates to a kind of collet chuck group, due to collet chuck body If each limiting section is equipped with a thrust surface, and since the cutter is equipped with multiple abutment faces, when its of cutter there are two limiting section In two abutment faces by collet chuck body two thrust surfaces limit when, can stop push cutter, allow user to learn one Exact anchor point makes when being that cutter is installed in the collet chuck body every time, and the length that collet chuck body is stretched out at the processing end is equal Unanimously, guarantee collet chuck body to the clamping effect of cutter；Furthermore the section at the installing end is a polygon, and each limiting section Tool there are two confined planes, two confined planes of each limiting section can clip cutter installing end, and be avoided that cutter in processing, knife Have opposite collet chuck body to rotate, leads to the situation generation of machining accuracy error, play the role of aligned cutting tool.
