Abstract

The invention relates to a guide-type collet. The guide-type collet comprises a collet body and an extending section. The collet body is provided with a sleeve hole in the center so that the collet body sleeves a cutter. The collet body is provided with at least one adjusting opening in the sleeve hole of the outer ring wall surface such that the collet body has elasticity. The extending section is correspondingly arranged at one end of the collet body and in the structure of an annular straight sleeve.

Description

Guiding type collet chuck

Technical field

The present invention relates to a kind of guiding type collet chuck, refer in particular to one can assist to concentrate cutting fluid at tool sharpening, And avoid the tool tube clamping structure of cutter disalignment.

Background technology

Along with the progress of industrial processes science and technology, multifunctional processor tool (such as: CNC lathe) of application automatization Object is carried out such as cutting, boring etc. processing action, controls facility with replacement tradition with manpower and add Work is a kind of gradually universal processing kenel, and optionally switches each in response to various processing action demands The cutter of style and various sizes is the characteristic of automatic multi-function machining machine and tool.

And in existing machine for automatic working category, in a kind of cutter holding dress having from internal ejection cutting fluid In putting, frequently by a clamping collet chuck and a lock nut, cutter is fixed in time clamping cutter, and clamp It is for an additional fixing plate with collet chuck itself, the problem the most easily having fixing upper disalignment, such one Be easily caused and related cause cutter itself eccentric and affect processing, in addition the cutting fluid from internal ejection be by Confluxing in portion, is therefore likely to the gap by clamping collet chuck and runs off, and causes cutting fluid to be difficult to concentrate Being ejected into and pile up at the processing of cutter bits, the chip removal effect that therefore can obtain is given a discount, and the most just leads Cause have to carry out chip removal by more outer jet cutting fluid, in the upper sight of application, has its weak point, Therefore described before taking a broad view of, the present inventor thinks and designs a kind of guiding type collet chuck having water shutoff function, with Phase is improved for the disappearance of prior art, and then the enforcement in enhancement industry utilizes.

Summary of the invention

Because aforesaid the deficiencies in the prior art point, the present invention design one possess novelty, progressive and The guiding type collet chuck of the tool water shutoff function of the patent requirements such as industry applications, to overcoming the difficult point of prior art.

For reaching above-mentioned purpose, the technology used in the present invention means are a kind of guiding type collet chuck of design, its bag Containing: a collet chuck body, it is to have a trepanning in central authorities to be sheathed on a cutter with correspondence, and this collet chuck body Outer shroud wall at this trepanning is provided with at least one adjustment opening, and then allows this collet chuck body have elasticity； And an extension, it is correspondingly arranged on one end of this collet chuck body, is a ring-type straight sleeve structure.

Wherein, this adjustment opening is that elongated is distributed in this collet chuck body.

Wherein, this collet chuck body system one end is rear end, and the other end is front end.

Wherein, this rear end of this collet chuck body is located in this extension.

Wherein, the internal ring wall in this extension is further provided with an anti-seal cage groove.

The guiding type collet chuck of the tool water shutoff function of the present invention provides one can guide assembling cutter in the upper system of design, order It is aligned in the axle center of cutter holding seat exactly, and provides isolation cutting fluid to prevent what it from leaking outside to ask simultaneously Topic, has splendid application portability, has splendid application portability.

And in order to allow above-mentioned purpose, technical characteristic and actual implement after incremental become apparent from understandable, in Hereinafter preferably implement example to assist a ruler in governing a country corresponding relevant graphic be described in detail by being.

Detailed description of the invention

Please refer to Fig. 1 to shown in 3, the present invention proposes a kind of guiding type collet chuck, and it is to assemble in a cutter To fix a cutter 80 and by lock nut 70 packing among tool grip slipper 90, it is the most concrete in one Embodiment can comprise collet chuck body 10 and an extension 20.

Aforesaid collet chuck body 10 is to have a trepanning 11 in central authorities to be sheathed on correspondence on this cutter 80, and This collet chuck body 10 outer shroud wall at this trepanning 11 is provided with at least one adjustment opening 12, and it maybe can be in Elongated is distributed in this collet chuck body 10, and then allows this collet chuck body 10 have elasticity, overlaps in this lock nut 70 It is located at that this collet chuck body 10 is outer and packing or unclamp this collet chuck body 10 of Shi Kerang this cutter 80 is produced clamping And the structural change loosened, additionally, this collet chuck body 10 is one end is rear end 13, the other end is front end 14, To meet the skew wall face of an opening of this lock nut 70.

This extension 20 aforesaid is correspondingly arranged on one end of this collet chuck body 10, maybe can be provided at this rear end In place of 13, it is a ring-type straight sleeve structure, and then can corresponding matching open in the one of this cutter holding seat 90 One of mouth guides straight trough 91, and then produces an effect guided, and disalignment when avoiding assembling, and in Between the outer shroud wall of this extension 20 and this guiding straight trough 91, one first anti-seal cage 60 can be set further, This first anti-seal cage 60 is compressed to reach waterproof function.

And be further provided with an anti-seal cage groove 21 in this extension 20 1 internal ring wall, and then can be in being sheathed on Time on this cutter 80, play an envelope by arranging one second anti-seal cage 61 on this anti-seal cage groove 21 Close waterproof function.

Coordinate referring to shown in Fig. 4 the most further, wherein in a deformation implementation aspect, this collet chuck body 10 This front end 14 or may correspond to the opening of a cutter holding seat 90A, this extension 20 is then corresponding to one The guiding straight hole 71A of one opening of lock nut 70A, and and then it is provided with the first anti-seal cage 60 and generation etc. With above-mentioned water-proof function；Second anti-seal cage 61 is located between this extension 20 and this cutter 80, and quilt Compress and produce waterproof effect.And wherein this lock nut 70A use on can without in collet chuck body 10 additionally Plus a disc, and by the collocation with this extension 20, and then when making it clamp with tool clamp holder, no The problem having seepage cutting fluid occurs, and more can save the time that cutter is replaced simultaneously.

Being changed by the guiding type collet chuck of present invention clever thought in design, it provides one can guide assembling cutter 80, make it be aligned in the axle center of this cutter holding seat 9090A exactly, and provide simultaneously isolation cutting fluid with Prevent the problem that it leaks outside, there is splendid application portability, do not caned for prior art and person, thus visible Its incremental place.

Described above it is merely exemplary for the purpose of the present invention, and nonrestrictive, ordinary skill people Member understand, in the case of the spirit and scope limited without departing from claim, can many modifications may be made, Change or equivalence, but within falling within protection scope of the present invention.
