Abstract

The utility model relates to a novel three-jaw chuck for fixing cylindrical workpieces. The novel three-jaw chuck comprises a chuck body, clamping jaws, a big gear and a small gear as well as three clamping heads and three guide grooves, wherein a spanner inserting hole is formed in the side surface of the chuck body, and three fixing grooves for placing the clamping jaws are formed on the end surface of the chuck body; the big gear and the small gear are mutually engaged and are both arranged in the chuck body; the upper end of the small gear is communicated with the spanner inserting hole; a thread groove is formed at the other end of the big gear; convex blocks a matched with the thread groove are arranged on the bottom surfaces of the clamping jaws; the guide grooves are formed on the end surface of the chuck body, which is located at the same side with the fixing grooves; the clamping heads are arranged in the guide grooves; convex blocks b matched with the thread groove are also arranged on the bottom surfaces of the clamping heads; the convex blocks a and the convex blocks b are opposite in thread direction; clamping blocks are arranged in a position on the top surfaces of the clamping heads, close to the center of the chuck body; when the small gear drives the big gear to rotate, the thread groove on the big gear drives the clamping jaws and the clamping heads to move in the radial direction of the chuck body at the same time, and the clamping heads and the clamping jaws are opposite in moving direction.

Description

A kind of novel scroll chuck
Technical field
The utility model relates to the fixture of the fixation workpiece on a kind of lathe, and especially a kind of scroll chuck of fixation workpiece belongs to the machine tool accessory technical field.
Background technology
The device of fixation workpiece all adopts scroll chuck on most of lathes, and this device comprises chuck body and three claws, in chuck body, is fixed be meshing with each other pinion and gear wheel, and pinion is connected with spanner jack on the chuck body; Gear wheel is provided with thread groove; All be provided with the projection that matches with this thread groove on each claw; When through the spanner rotation pinion in the spanner patchhole, gear wheel also rotates thereupon, and the rotation of gear wheel must cause the radial motion of claw along chuck body.During use, all be the center that claw is left chuck body, then to be processed inserted in the chuck body, again claw is turned to be processed, clamp to be processed.But many times to be processed all is cylindrical workpiece, adopts this sample loading mode to fix, and is easy to make workpiece generation radial deformation, causes a large amount of condemned MAT'Ls, has reduced the production efficiency and the quality of production greatly.
The utility model content
The utility model purpose is for the deficiency that overcomes prior art a kind of novel scroll chuck to be provided, and it can stationary cylinder shape to be processed.
For achieving the above object, the technical scheme that the utility model adopts is: a kind of novel scroll chuck comprises chuck body, claw, gear wheel and pinion; The side of said chuck body is provided with a spanner jack, and its end face is provided with three holddown grooves of placing claw; Said gear wheel and pinion are meshing with each other, and all are located in the chuck body; The upper end of said pinion is communicated with the spanner jack; The other end of said gear wheel is provided with thread groove; Said claw bottom surface is provided with the projection a that matches with thread groove; Also comprise three dops and three gathering sills; On the said gathering sill, and be positioned on the end face with chuck body and holddown groove homonymy; Said dop is located in the gathering sill; The bottom surface of said dop also is provided with the projection b that matches with thread groove, and the hand of spiral of projection a and projection b is opposite; On the end face of said dop, on the position near the chuck body center, be provided with fixture block; When said pinion drove gear wheel and rotates, the thread groove on the gear wheel drove the radial motion along chuck body of claw and dop simultaneously, and the direction of motion of dop and claw is opposite.
Preferably, said each dop all is positioned in the middle of two adjacent claws.
Because the utilization of technique scheme, the utility model compared with prior art has advantage:
A kind of novel scroll chuck of the utility model scheme, when the processing cylindrical workpiece, dop stretches in the cylindrical workpiece, lives workpiece in internal fixation; The while claw is the clamping work pieces in the outside of workpiece also.The utility model scheme stationary cylinder shape workpiece simple to operate effectively reduces directly the scrappage that stationary cylinder shape workpiece externally produces, and enhances productivity and the quality of production.
Description of drawings
Below in conjunction with accompanying drawing the utility model technical scheme is described further:
Accompanying drawing 1 is the stereogram of the novel scroll chuck of the utility model;
Accompanying drawing 2 is the exploded view of the novel scroll chuck of the utility model;
Accompanying drawing 3 is the cutaway view at A place in the accompanying drawing 1;
Wherein: 1, chuck body; 2, claw; 3, dop; 4, fixture block; 5, spanner patchhole; 6, pinion; 7, gear wheel; 8, thread groove; 9, holddown groove; 10, gathering sill.
The specific embodiment
Below in conjunction with accompanying drawing and specific embodiment the utility model is done further to specify.
Accompanying drawing 1,2,3 is the described a kind of novel scroll chuck of the utility model, comprises chuck body 1, claw 2, gear wheel 7 and pinion 6; The side of said chuck body 1 is provided with a spanner jack 5, and its end face is provided with three holddown grooves 9 of placing claw 2; Said gear wheel 7 is meshing with each other with pinion 6, and all is located in the chuck body 1; The upper end of said pinion 6 is communicated with spanner jack 5; The other end of said gear wheel 7 is provided with thread groove 8; Said claw 2 bottom surfaces are provided with the projection a (not shown) that matches with thread groove 8; Also comprise three dops 3 and three gathering sills 10; Said gathering sill 10 is positioned on the chuck body 1, and is positioned on the end face with holddown groove 9 homonymies; Said dop 3 is located in the gathering sill 10; The bottom surface of said dop 3 also is provided with the projection b (not shown) that matches with thread groove 8, and the hand of spiral of projection a and projection b is opposite; On the end face of said dop 3, on the position near chuck body 1 center, be provided with fixture block 4; When said pinion 6 drove gear wheel 7 rotations, the thread groove 8 on the gear wheel 7 drove claw 2 and the radial motion of dop 3 along chuck body 1 simultaneously, and dop 3 is opposite with the direction of motion of claw 2; Said each dop 3 all is positioned in the middle of two adjacent claws 2.
Because the utilization of technique scheme, the utility model compared with prior art has advantage:
A kind of novel scroll chuck of the utility model scheme, when the processing cylindrical workpiece, dop stretches in the cylindrical workpiece, lives workpiece in internal fixation; The while claw is the clamping work pieces in the outside of workpiece also.The utility model scheme stationary cylinder shape workpiece simple to operate effectively reduces directly the scrappage that stationary cylinder shape workpiece externally produces, and enhances productivity and the quality of production.
Below only be the concrete exemplary applications of the utility model, the protection domain of the utility model is not constituted any limitation.All employing equivalents or equivalence are replaced and the technical scheme of formation, or any to move mode dull and stereotyped described in the utility model, all drop within the utility model rights protection scope.
