Description
Technical field
The utility model relates to a kind of for gripping the technical field of the collet chuck structure aspect of drill bit, espespecially a kind of there is enough chucking powers can be for being applicable to clamp the collet chuck structure of long edge drilling bit and short edge drilling bit.
Background technology
TaiWan, China is announced the general common chuck structure being applied on cutter or drill grinder of M284483 patent, its structure is please refer to shown in Fig. 1 to Fig. 3, mainly comprise a fixture 10, one nut 11 and be folded in the collet chuck 12 between this fixture 10 and this nut 11, wherein this collet chuck 12 comprises before perforation, rear end face Yi center trepanning 13, one of convergent rear cone section 14 backwards, convergent and be longer than an inner cone section 15 of this rear cone section 14 forward, by front end face, extend to this rear cone section 14 and the non-through a plurality of front profile groove 16 to rear end face and extend to this inner cone section 15 and the non-through a plurality of rear profile groove 17 to this front end face by rear end face.Between each two adjacent front profile groove 16, form respectively a jaw 18, the medial surface of the front end of this jaw 18 has respectively the fixture block 19 that trepanning 13 center, Chao Gai center is convexly equipped with, and the length of this fixture block 19 is greater than half of this inner cone section 15.The front end of the fixture block 19Yu Gai center trepanning 13 of the plurality of jaw 18 surrounds a folder hole 190.Wherein, this front profile groove 16 can be respectively respectively 8 roads or can be respectively respectively 6 roads with the quantity of this rear profile groove 17.
In Fig. 3, can find out, wherein the length of the inner cone section 15 of existing collet chuck 12 is H, and the length of fixture block 19 is h.Therefore, when utilizing the drill bit 20 of existing collet chuck 12 clamping short sword swords 21, (blade 21 of this drill bit 20 is arranged in this folder hole 190, when the handle of a knife 22 of this drill bit 20 is arranged in the center trepanning 13 of these folder hole 190 rear sides), the blade 21 of this drill bit 20 just can be greater than because of the length of this fixture block 19 this inner cone section 15 half (it approaches the rear end of inner cone section 15), so just only can only protrudingly expose a bit of length L of front end of this collet chuck 12.And so short length may be used after the short time and can cannot to use because of the front end that wearing and tearing approach collet chuck 12, very cause and can can't bear to use because of the restriction of working depth, therefore existing collet chuck 12 only can only be applicable to clamp the drill bit 20 of rimmer knife sword 21, and be not suitable for the drill bit 20 of clamping short sword sword 21, so using certain length once the blade 21 of this drill bit 20 just cannot use and need abandon, yet this drill bit 20 in fact still has at least one section of not short blade 21 of being clamped by this fixture block 19 cannot be filled the use of part and has slatterned, especially can make therefore significantly shorten the service life of the drill bit 20 of rimmer knife sword 21.
In view of this, the design people is for not attaining perfect caused many disappearances and inconvenience in the design of above-mentioned collet chuck structure, and deeply design, and active research improvement has a fling at and development and Design goes out this case.

The specific embodiment
In order further to explain the technical solution of the utility model, below by specific embodiment, the utility model is elaborated.
Refer to shown in Fig. 4 to Fig. 9, show that collet chuck structure described in the utility model comprises the rear cone section of a center trepanning 30, one 40, one inner cone section 50, an annular groove 60, a plurality of front profile groove 70 and a plurality of rear profile groove 80.Wherein:
This center trepanning 30 connects front and rear end, and can wear for a drill bit 20.
This rear cone section 40 is positioned at rear end, and is gradually-reducing shape backwards.
This inner cone section 50 is positioned at front end, and is gradually-reducing shape forward, and the length of this inner cone section 50 is greater than this rear cone section 40.
This annular groove 60 is located at outer peripheral face, and position is between this forward and backward cone section 50,40.
The plurality of front profile groove 70 extends to this rear cone section 40 by this inner cone section 50, and it penetrates into this center trepanning 30 by outer peripheral face.The front end of this front profile groove 70 extends to front end face and opening-like, and rear end is non-through is closed to rear end face.Between each two adjacent front profile groove 70, form respectively a jaw 71, the medial surface of the front end of this jaw 71 has respectively the blade 21 that a fixture block 72 that trepanning 30 center, Chao Gai center is convexly equipped with is available for clamping this drill bit 20, and the length h ' of this fixture block 72 is less than the length H of this inner cone section 50 half (being h ' <H/2).The front end of the fixture block 72Yu Gai center trepanning 30 of the plurality of jaw 71 surrounds a folder hole 73, and this folder hole 73 can wear for the blade 21 of this drill bit 20, and the center trepanning 30 of these folder hole 73 rear sides can wear for the handle of a knife 22 of this drill bit 20.
The plurality of rear profile groove 80 extends to this inner cone section 50 by this rear cone section 40, and penetrates into this center trepanning 30 by outer peripheral face.The plurality of rear profile groove 80 is and is crisscross arranged with the plurality of front profile groove 70, and includes a plurality of open ditches 81 and a plurality of sealing ditch 82.The front end of the plurality of open ditch 81 is non-through is closed to front end face, and rear end penetrates into rear end face and be opening-like.The front and back ends of the plurality of sealing ditch 82 is all non-through is closed to front and rear end, and rear end face is not dissectd in the rear end of this sealing ditch 82, but have, links the contiguous block 83 of both sides furrow bank so that it forms closed.
In the utility model, the quantity of this front profile groove 70 and this rear profile groove 80 is respectively respectively 8 roads, and wherein this rear profile groove 80 comprises the open ditch 81 in 4 roads and 4 roads sealing ditch 82.In addition, the quantity of this front profile groove 70 and this rear profile groove 80 can be also respectively respectively 6 roads, and wherein this rear profile groove 80 comprises the open ditch 81 in 3 roads and 3 roads sealing ditch 82.
Because collet chuck structure of the present utility model can be less than by the length h ' of this fixture block 72 half the structural design of length H of this inner cone section 50, make this collet chuck when the drill bit 20 of clamping short sword sword 21, the blade 21 of this drill bit 20 can protrudingly expose the long segment length L ' of front end of this collet chuck.Especially, utilize the plurality of rear profile groove 80 to be with the plurality of front profile groove 70 design being crisscross arranged, make the quantity of the opening-like open ditch 81 in the rear end of the plurality of rear profile groove 80 can be less than the quantity of this front profile groove 70, therefore just can make the formed a plurality of jaws 71 of the plurality of front profile groove 70 can therefore there is stronger rigidity, the relative fixture block 72 that just can make the plurality of jaw 71 front ends has larger clamping power, and then is enough to make the drill bit 20 clamped by it grinding or adding the situation that can not produce beat or rock man-hour.Particularly, its available longer time of protruding blade exposing 21, and because its blade 21 of being clamped by this fixture block 72 (be positioned at this collet chuck among blade 21) only only has a bit of, therefore can make this drill bit 20 be effectively used, and then therefore effectively cut the waste and significantly reduce the cost of consumptive material.
Above-described embodiment and accompanying drawing non-limiting product form of the present utility model and style, suitable variation or modification that any person of an ordinary skill in the technical field does it, all should be considered as not departing from patent category of the present utility model.
