Abstract
The utility model relates to a spring collet which comprises a spring collet body, a spring collet shell and a machine tool spindle flange plate, wherein the head part of the spring collet body is arranged in the spring collet shell, the tail part of the spring collet body is arranged in the machine tool spindle flange plate, the spring collet body can slide relative to the spring collet shell and the machine tool spindle flange plate, the tail part of the spring collet is fixedly provided with a pull rod, the head part of the spring collet body is provided with an inner conical hole, the head part of the spring collet body is provided with an outer conical surface matched with the conical surface of the inner conical hole, the spring collet body is provided with an open slot which axially extends from the head part to the middle part, and the open slot is filled with an elastic material layer. The spring collet has the beneficial effects that as the open slot of the spring collet body is filled with the elastic material layer, the open slot can be elastically sealed, the clamping effect of the spring collet body cannot be affected; and when a part is processed, the dust or scrap iron of a grinding wheel can be effectively prevented from entering the matched position of the conical surfaces of the spring collet shell and the spring clamp body or being accumulated in the open slot, and thus the clamping precision of the part can be improved.
Description
(1) technical field
The utility model relates to a kind of clamping device of Machining of Shaft-type Parts, relates in particular to a kind of collet.
(2) background technology
Existing collet, mainly comprise the chuck body, the chuck shell, and the machine tool chief axis ring flange that is fixedly arranged on this chuck shell rear, the head of this chuck body places in the described chuck shell, the afterbody of this chuck body places in the described machine tool chief axis ring flange, described chuck body can described relatively chuck shell and the slippage of described machine tool chief axis ring flange, the afterbody of described chuck body is installed with pull bar, the head of described chuck shell is provided with internal taper hole, the head of described chuck body is provided with the male cone (strobilus masculinus) with described internal taper hole cone match, and described chuck body is provided with the open slot that extends axially from the head to the middle part.When the working shaft-like part, adopt collet to clamp axial workpiece, because the axiality of collet clamping is difficult for crushing piece surface, thereby makes collet be widely used than chuck height during clamping.But the collet of this structure can be easy to enter from open slot the cone match of chuck shell and chuck body at processing parts process medium plain emery wheel ash or iron filings, also can be accumulated in the open slot, thereby cause part to beat greatly, reduces the parts fixation precision.
(3) summary of the invention
There is above-mentioned deficiency in the prior art in order to overcome, the utility model provides a kind of collet simple in structure, easy to use, it can prevent effectively in the processing parts process that emery wheel ash or iron filings from entering the cone match of chuck shell and chuck body or being accumulated in the open slot clamping precision of raising part from open slot.
The technical scheme in the invention for solving the technical problem is: a kind of collet, comprise the chuck body, the chuck shell, and the machine tool chief axis ring flange that is fixedly arranged on this chuck shell rear, the head of this chuck body places in the described chuck shell, the afterbody of this chuck body places in the described machine tool chief axis ring flange, described chuck body can described relatively chuck shell and the slippage of described machine tool chief axis ring flange, the afterbody of described chuck body is installed with pull bar, the head of described chuck shell is provided with internal taper hole, the head of described chuck body is provided with the male cone (strobilus masculinus) with described internal taper hole cone match, described chuck body is provided with the open slot that extends axially from the head to the middle part, is filled with elastomeric layer in the described open slot.
The utility model in use, axial workpiece is installed in the chuck body, pull back pull bar then, pull bar drives the chuck body and moves backward relative to machine tool chief axis ring flange and chuck shell, and the head of chuck body inwardly shrinks under the conical surface extruding of chuck shell, thereby the clamping part just can be processed part then.
The beneficial effects of the utility model are: owing to filled elastomeric layer in the open slot of chuck body, thereby open slot is carried out elastic packing, not only can not influence the clamping effect of chuck body, can also prevent effectively in the processing parts process that emery wheel ash or iron filings from entering the cone match of chuck shell and chuck body or be accumulated in the open slot from open slot, thereby improve the clamping precision of part.
(4) description of drawings
Fig. 1 is a front view of the present utility model;
Fig. 2 is a vertical view of the present utility model.
(5) specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
With reference to Fig. 1, Fig. 2, a kind of collet, comprise chuck body 1, chuck shell 2, and the machine tool chief axis ring flange 3 that is fixedly arranged on these chuck shell 2 rears, the head of this chuck body 1 places in the described chuck shell 2, the afterbody of this chuck body 1 places in the described machine tool chief axis ring flange 3, described chuck body 1 can described relatively chuck shell 2 and described machine tool chief axis ring flange 3 slippages, the afterbody of described chuck body 1 is installed with pull bar 4, the head of described chuck shell 2 is provided with internal taper hole 5, the head of described chuck body 1 is provided with the male cone (strobilus masculinus) 6 with described internal taper hole 5 cone match, described chuck body 1 is provided with the open slot 7 that extends axially from the head to the middle part, is filled with elastomeric layer 8 in the described open slot 7.The utility model in use, axial workpiece is installed in the chuck body 1, pull back pull bar 4 then, pull bar 4 drives chuck body 1 and moves backward relative to machine tool chief axis ring flange 3 and chuck shell 2, and the head of chuck body 1 inwardly shrinks under the conical surface extruding of chuck shell 2, thereby the clamping part just can be processed part then.Owing in the open slot 7 of chuck body 1, filled elastomeric layer 8, thereby open slot 7 is carried out elastic packing, not only can not influence the clamping effect of chuck body 1, can also prevent effectively in the processing parts process that emery wheel ash or iron filings from entering the cone match of chuck shell 2 and chuck body 1 or be accumulated in the open slot 7 from open slot 7, thereby improve the clamping precision of part.
