Abstract
The invention discloses a three-jaw chuck which comprises a chuck body, jaw rails, jaws, an inner fluted disc and a small bevel gear; the jaws are arranged on the jaw rails which are uniformly distributed on the chuck body; the inner fluted disc is arranged on the chuck body; the lower end of the inner fluted disc is connected with the small bevel gear; a spanner insertion square hole is arranged on the small bevel gear; an elastomer is arranged at the bottom in the spanner insertion square hole; a convex surface piece is arranged above the elastomer; the elastomer is a spring; and according to the three-jaw chuck, because the elastomer is arranged at the bottom in the spanner insertion square hole, the convex surface piece is arranged above the elastomer, after a freshman or a careless person clamps a work piece, a spanner is automatically separated from the spanner insertion square hole, so that the problems that a machine tool is started in case that the spanner is forgotten to be removed, as a result, the machine tool is damaged or personal accidents are caused are solved.
Description
Technical field
The present invention relates to the clamping tool that uses on a kind of lathe, particularly a kind of novel scroll chuck belongs to the machine tool accessories technical field.
Background technology
Extensively on lathe, machine components are processed employed clamping tool at present and be mainly scroll chuck; All be provided with bevel pinion on the general scroll chuck; Have spanner on the bevel pinion and insert square hole, rotate bevel pinion through spanner and reach control claw chucking workpiece.But some new hands or some careless people can forget that taking down spanner just starts lathe after accomplishing clamping work pieces, just may cause this moment lathe to damage or cause personal injury.
Summary of the invention
Technical problem to above-mentioned existence the objective of the invention is: after having proposed a kind of completion clamping work pieces, spanner can break away from the scroll chuck that spanner inserts square hole automatically.
Technical solution of the present invention is achieved in that a kind of scroll chuck, comprises chuck body, claw track, claw, interior fluted disc and bevel pinion; Said claw is installed on the chuck body on the equally distributed claw track; Fluted disc is installed in the chuck body in said; The lower end of fluted disc connects bevel pinion in said; Have spanner on the said bevel pinion and insert square hole; The bottom that said spanner inserts in the square hole is provided with elastomer; Said elastomeric top is provided with convex tablets.
Preferably, said elastomer is a spring.
Because the utilization of technique scheme, the present invention compared with prior art has advantage:
Scroll chuck of the present invention; Because the bottom that spanner inserts in the square hole is provided with elastomer; Put on elastomeric and be provided with convex tablets; After the people of some new hands or carelessness accomplished clamping work pieces, spanner can break away from spanner automatically and insert square hole, had avoided because of forgetting that taking down spanner causes lathe to damage or cause personal injury with regard to starting lathe.

Below in conjunction with accompanying drawing technical scheme of the present invention is described further:
Accompanying drawing 1 is the stereogram of scroll chuck of the present invention;
Accompanying drawing 2 is the front section view of scroll chuck of the present invention;
Accompanying drawing 3 is the partial enlarged drawing of accompanying drawing 2;
Wherein: 1, chuck body; 2, claw; 3, claw track; 4, interior fluted disc; 5, bevel pinion; 6, spanner inserts square hole; 7, elastomer; 8, convex tablets.
The specific embodiment
Below in conjunction with accompanying drawing the present invention is described.
Of the present invention a kind of scroll chuck shown in accompanying drawing 1-3 comprises chuck body 1, claw track 3, claw 2, interior fluted disc 4 and bevel pinion 5; Said claw 2 is installed on the chuck body 1 on the equally distributed claw track 3; Fluted disc 4 is installed in the chuck body 1 in said; The lower end of fluted disc 4 connects bevel pinion 5 in said; Have spanner on the said bevel pinion 5 and insert square hole 6; The bottom that said spanner inserts in the square hole 6 is provided with elastomer 7; The top of said elastomer 7 is provided with convex tablets 8; Said elastomer 7 is a spring.
Because the utilization of technique scheme, the present invention compared with prior art has advantage:
Scroll chuck of the present invention; Because the bottom that spanner inserts in the square hole is provided with elastomer; Put on elastomeric and be provided with convex tablets; After the people of some new hands or carelessness accomplished clamping work pieces, spanner can break away from spanner automatically and insert square hole, had avoided because of forgetting that taking down spanner causes lathe to damage or cause personal injury with regard to starting lathe.
The foregoing description only is explanation technical conceive of the present invention and characteristics; Its purpose is to let the personage that is familiar with this technology can understand content of the present invention and implements; Can not limit protection scope of the present invention with this; All equivalences that spirit is done according to the present invention change or modify, and all should be encompassed in protection scope of the present invention.
