Abstract
The utility model relates to a chuck which comprises a body, wherein, the two ends of the body are respectively provided with a top surface and a bottom surface, an axle hole runs through the top surface and the bottom surface along the axle center of the body, a cone-shaped clamping section, a neck axle and a connecting section are sequentially arranged on the body between the top surface and the bottom surface, a plurality of cut flutes are disposed on the wall surface of the body along the axial direction, the axle hole positioned on the clamping section is a polygonal star hole. The utility model adopts the technical proposal that the axle hole positioned on the clamping section of the chuck is designed to the polygonal star hole, so the polygonal workpiece or tool can be clamped in the vertex angles of the polygonal star with high clamping rate.
Description
Technical field
The utility model relates to a kind of clamping part that is used for lathe workpiece or instrument, relates in particular to the chuck of polygon workpiece of a kind of clamping or instrument.
Background technology
As shown in Figure 1, be generally to be applied to the workpiece that lathe uses or the chuck of instrument, this chuck body 1 is for having the microscler cone of central shaft hole 6, the end face 9 and bottom surface 10 that should run through chuck body 1 for central shaft hole 6, be divided into cone shape gripping section 5 between the end face 9 of described body 1 and the bottom surface 10 successively, neck axle 3 and linkage section 2, insert in this central shaft hole 6 for making things convenient for workpiece or cutter (not shown), the wall Back stroke of chuck body 1 is provided with the profile groove 4 that 3 roads communicate with axis hole 6, one section of profile groove 4 extends to end face 9, another section extends to neck axle 3, make chuck body 1 have elasticity, can be out of shape workpiece or the instrument clamped when inserting workpiece or cutter, and elasticity the best of gripping section 5, its flexible amplitude is big.But because common chuck, when clamping polygon workpiece or instrument, very inconvenience, it is low to clamp probability.
Summary of the invention
The utility model provides easy to use at deficiency of the prior art, the chuck of suitable clamping polygon workpiece or instrument.
In order to solve the problems of the technologies described above, the utility model is solved by following technical proposals:
Chuck, comprise body, the two ends of described body are respectively end face and bottom surface, one axis hole runs through this end face and bottom surface along the body axle center, be divided into cone shape gripping section, neck axle and linkage section between the end face of described body and the bottom surface successively, described body wall upper edge is axially arranged with several profile grooves, and the described axis hole that is positioned at gripping section is polygonal star hole.
As preferably, the described axis hole that is positioned at gripping section is positive octagonal star hole, and described profile groove is 4.
As preferably, the described axis hole that is positioned at gripping section is positive 12 jiaos of star holes, and described profile groove is 3.
As preferably, the described drift angle that is positioned at the angle star on the gripping section is the arc transition angle.
By the chuck of the technical solution of the utility model, the axis hole that will be positioned at gripping section is designed to polygonal star hole, is convenient to polygon workpiece or tool holding in the drift angle of polygonal star, clamping rate height.

The specific embodiment
Below in conjunction with the accompanying drawing and the specific embodiment the utility model is described in further detail:
Embodiment 1
As Fig. 2, chuck shown in 3, comprise body 1, the two ends of described body 1 are respectively end face 9 and bottom surface 10, one axis hole 6 runs through this end face 9 and bottom surface 10 along body 1 axle center, be divided into cone shape gripping section 5 between the end face 9 of described body 1 and the bottom surface 10 successively, neck axle 3 and linkage section 2, described body 1 wall upper edge is axially arranged with 4 profile grooves 4, one section of profile groove 4 extends to end face 9, another section extends to neck axle 3, make chuck body 1 have elasticity, the axis hole 6 of described gripping section 5 is positive octagonal star hole, and wherein 4 drift angles 7 separately of 6 drift angles in this octagonal star hole lay respectively on the gripping section 5 of adjacent 2 profile grooves 4, and all the other 4 drift angles 7 are positioned on the profile groove 4.And the drift angle 7 that is positioned on the gripping section 5 is the arc transition angle.Reduce the mutual friction mutually of workpiece and drift angle.
Present embodiment is applicable to tetragonal workpiece of clamping or instrument, and adopts tetragonal workpiece of octagonal star hole clamping or instrument, and the clamping rate has increased by one times.
As Fig. 4, chuck shown in 5, comprise body 1, the two ends of described body 1 are respectively end face 9 and bottom surface 10, one axis hole 6 runs through this end face 9 and bottom surface 10 along body 1 axle center, be divided into cone shape gripping section 5 between the end face 9 of described body 1 and the bottom surface 10 successively, neck axle 3 and linkage section 2, described body 1 wall upper edge is axially arranged with 3 profile grooves 4, one section of profile groove 4 extends to end face 9, another section extends to neck axle 3, make chuck body 1 have elasticity, the axis hole 6 of described gripping section 5 is positive 12 jiaos of star holes, wherein 9 drift angles of 12 drift angles in these 12 jiaos of star holes lay respectively on the gripping section 5 of adjacent 2 profile grooves 4, promptly be equipped with 3 drift angles 7 on the gripping section 5 of every adjacent 2 profile grooves 4, all the other 3 drift angles are positioned on the profile groove 4.And the drift angle 7 that is positioned on the gripping section 5 is the arc transition angle.Reduce the mutual friction mutually of workpiece and drift angle.
When present embodiment is applicable to hexagonal workpiece of clamping or instrument, adopt 12 jiaos of hexagonal workpiece of star hole clamping or instrument, the clamping rate has increased by one times, when being suitable for tetragonal workpiece of clamping or instrument, adopt 12 jiaos of tetragonal workpiece of star hole clamping or instrument, the clamping rate has increased by two times
In a word, the above only is preferred embodiment of the present utility model, and all equalizations of being done according to the utility model claim change and modify, and all should belong to the covering scope of the utility model patent.
