Description
Technical field
The present invention relates to a kind of collet of machinery manufacturing industry.
Background technology
Existing a kind of patent No. discloses a kind of structure for the Chinese utility model patent that the CN91218617.8 name is called " using collet " more, its structure is that chuck body one end is a cylinder, two keyways of 180 ° of being separated by are arranged on the cylinder outer surface, and the center has and is used for screwing in the internal thread of handling leading screw; The other end is a cone, there is a hole at the cone center, and cone dignity upper edge circumference evenly has mounting hole axial arranged more than two, the mid-slide block of each mounting hole, close joining of conical bore on plain line in the center of slide block end face and the lathe rotating shaft, the bottom surface of slide block contacts with workpiece; It is characterized in that apart from cylinder one end appropriate location, respectively bore an aperture perpendicular to each mounting hole wall, make straight trough between two apertures and the taper seat handing-over line, also occupy aperture on the slide block relevant position, chuck body and slide block are run through with a spring steel wire.The shortcoming of this design is to need the turnover position of folder in folder hole of processing to be difficult to the location, so it is inconvenient to operate; Also have this design bad as the elastic force effect of the outside expanding of slide block by playing steel wire, because it is too thin to play steel wire, corrodes easily and rupture or hinders and lose deformability, service life is shorter, thus design reasonable not enough.
Summary of the invention
Technical problem to be solved by this invention is the collet that a kind of long service life, good clamping effect, compact conformation are provided at above-mentioned prior art present situation.
The present invention solves the problems of the technologies described above the technical scheme that is adopted: a kind of collet, and it includes elastic mechanism;
It is characterized in that also including:

Spindle tube is enclosed within slide outside, the mouth end be provided with the diameter of slide progressively expanding reach cooperate, oppress the annular extrusion face of slide block towards central slide.
Preferably, described several piece fixture block and several piece slide block are equally distributed at circumferencial direction.
As preferably, described several piece fixture block and several piece slide block are four, and four fixture block shapes are identical, be stitched together constitute can holding workpiece sleeve.
Preferably, described diameter progressively expanding reach main body adopts the frustum shape, and accordingly, the annular extrusion face also is the conical surface, and slide block rear outside face also is the local conical surface.
Preferably, described chute adopts T-slot.
As improvement, be that screw connects between described several piece fixture block and the several piece slide block.
As preferred improvement, described elastic mechanism is that annular elastomeric top flat one side contacts mutually with the bottom surface of slide block, and the another side of annular elastomeric top flat contacts mutually with an end of described spring, and the other end of spring contacts mutually with support ring, and the another side of support ring and described punching trombone slide one end are inconsistent, and the punching trombone slide is connected the slide afterbody.Certainly, elastic mechanism also can adopt the flexure strip of other form, makes to support between the relative slide block to go up flexure strip, constitutes elastic mechanism.
Improve, described punching trombone slide leading portion divides the connecting portion that is provided with at interval equably at circumferencial direction again, and the connecting portion outer surface is shaped on connecting thread, is fixedly connected on by being threaded on the slide afterbody.
Further improve, convex with and the corresponding protuberance of slide block number on described annular elastomeric top flat one side, its end face of described protuberance is the inclined-plane, and the suitable and conflict of the inclined end face of this inclined-plane and slide block together.
At last, be provided with the keeper that makes things convenient for the workpiece location in the described spindle tube;
Described keeper is a setscrew nut, and this setscrew nut is arranged in the punching trombone slide and is fixed in fixed pedestal by screw thread, and the fixed pedestal inner surface is distributed with the gathering sill that the connecting portion for the punching trombone slide passes.
A kind of collet, it includes elastic mechanism;
It is characterized in that also including:
The several piece fixture block distributes on circumference, is used for the clamping workpiece;
The several piece slide block distributes on circumference, the anterior fixture block separately that connects correspondence, and the rear portion is spacing at the front end position of slide, can radially slide;
Elastic mechanism is provided with the slide block back, makes each slide block remain the trend of inwardly opening;
Slide, front end position are progressively expanding reach of diameter, have chute corresponding, that supply the slide block rear portion to embed at circumferencial direction;
Spindle tube, be enclosed within slide outside, the mouth end be provided with the diameter of slide progressively expanding reach cooperate, being provided with head in slide block inside is the seat that rises of taper, be provided with the pull bar that head is the conical surface in the seat that rises, this pull rod shaft is to extending spindle tube and being connected with tractive unit.
Compared with prior art, the invention has the advantages that: the first, the expanding of slide block is realized by the tubular spring, thereby has been eliminated the too thin situation of expanding spare, avoided expanding spare to corrode and the defective of fracture or wound mistake deformability easily, prolonged significantly service life; The second, be provided with the folder keeper in the chuck of the present invention, thereby guaranteed that every folder stretches into the distance of folder hole, make more convenient operation, easier, and the clamping effect is also better; Also have, by changing the claw form, can process the material of diameter greater than spindle tube, as other part external diameter and end face, and more flexible because of having positioner to make to insert and put, be desirable anchor clamps such as various instrument lathes, NC instrument lathe, the design's compact conformation, axially outreach is short, thereby has increased rigidity, improved crudy, and material-saving saving of labor, minimizing spreading anchor clamps time and versatility.
