Abstract
The utility model discloses a kind of chuck, comprise fastener, driving member, chuck body, claw and auxiliary claw, described fastener is at least two and prolongs chuck body radius and evenly to intert in the middle part of chuck body sidewall and fastener extends in chuck body cavity and engages with driving member lower surface, described driving member is arranged in chuck body cavity, described chuck body upper surface prolongs evenly be slidably installed at least three claws and claw of chuck body upper surface radius and extends in chuck body cavity and engage with driving member upper surface, described chuck body upper surface be evenly installed with at least three auxiliary claws and claw and claw spaced apart.This chuck, effectively stepping up workpiece is strengthened by auxiliary claw, define different institutions repeatedly fixing workpiece, solve the problem that the workpiece caused when claw does not clamp or claw loosens flies out or damages lathe, the effective unsafe factor reducing the workman of operation lathe.
Description
Technical field
The utility model relates to field of mechanical technique, is specially a kind of chuck.
Background technology
Chuck lathe is used for the mechanical device of clamping work pieces.Utilize and be distributed on moving radially of movable jaw on chuck body, the machine tool accessories of Workpiece clamping and location.Chuck is generally made up of chuck body, movable jaw and claw driving mechanism three part; lack effective protective device; especially workpiece does not clamp the workpiece the caused this kind of problem that flies out does not have good solution; certain unsafe factor is caused to the operator of lathe; when a problem occurs; often relatively more serious, for this reason, we propose a kind of chuck.
Utility model content
The purpose of this utility model is to provide a kind of chuck, to solve the problem proposed in above-mentioned background technology.
For achieving the above object, the utility model provides following technical scheme: a kind of chuck, comprise fastener, driving member, chuck body, claw and auxiliary claw, described fastener is at least two and prolongs chuck body radius and evenly to intert in the middle part of chuck body sidewall and fastener extends in chuck body cavity and engages with driving member lower surface, described driving member is arranged in chuck body cavity, described chuck body upper surface prolongs evenly be slidably installed at least three claws and claw of chuck body upper surface radius and extends in chuck body cavity and engage with driving member upper surface, described chuck body upper surface be evenly installed with at least three auxiliary claws and claw and claw spaced apart.
Preferably, described fastener is bolt or umbrella tooth.
Preferably, described driving member is plane fluted disc.
Preferably; described auxiliary claw comprises auxiliary claw base, movable securing member, support member, active connection, auxiliary claw head and protective layer; described auxiliary claw base is fixedly mounted on chuck body upper surface; described support member one end to be movably arranged in auxiliary claw base cavity by movable securing member and support member can with movable securing member for axle rotates; the described support member other end is movably arranged in auxiliary claw head cavity by active connection, and described protective layer is closely pasted onto auxiliary claw head upper surface.
Preferably, described protective layer material is rubber.
Compared with prior art, the beneficial effects of the utility model are: this chuck, effectively stepping up workpiece is strengthened by auxiliary claw, define different institutions repeatedly fixing workpiece, solve the problem that the workpiece caused when claw does not clamp or claw loosens flies out or damages lathe, the effective unsafe factor reducing the workman of operation lathe.

Fig. 3 is that the utility model assists claw structural representation.
In figure: 1, fastener, 2, driving member, 3, chuck body, 4, claw; 41, claw main body, 42, claw head, 5, auxiliary claw, 51, auxiliary claw base; 52, movable securing member, 53, support member, 54, active connection, 55, auxiliary claw head and 56, protective layer.
Detailed description of the invention
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
Refer to Fig. 1 to Fig. 3, the utility model provides a kind of technical scheme: a kind of full-automatic plastic-steel plants the energy-saving electric machine of tooth, comprise fastener 1, driving member 2, chuck body 3, claw 4 and auxiliary claw 5, described fastener 1 is at least two and prolongs chuck body 3 radius and evenly to intert in the middle part of chuck body 3 sidewall and fastener 1 extends in chuck body 3 chamber and engages with driving member 2 lower surface, fastener 1 is bolt or umbrella tooth, driving member 2 is plane fluted disc, driving member 2 is arranged in chuck body 3 chamber, chuck body 3 upper surface prolongs evenly be slidably installed at least three claws 4 and claw 4 of chuck body 3 upper surface radius and extends in chuck body 3 chamber and engage with driving member 2 upper surface, chuck body 3 upper surface be evenly installed with at least three auxiliary claws 5 and claw 5 and claw 4 spaced apart, auxiliary claw 5 comprises auxiliary claw base 51, movable securing member 52, support member 53, active connection 54, auxiliary claw head 55 and protective layer 56, auxiliary claw base 51 is fixedly mounted on chuck body 3 upper surface, support member 53 one end to be movably arranged in auxiliary claw base 51 chamber by movable securing member 52 and support member 53 can with movable securing member 52 for axle rotates, described support member 53 other end is movably arranged in auxiliary claw head 55 chamber by active connection 54, protective layer 56 is closely pasted onto auxiliary claw head 55 upper surface, protective layer 56 material is rubber, fastener 1 drives driving member 2, then the centripetal motion of claw 4 is driven, because the pitch of driving member 2 screw thread is equal, claw 4 move distance is equal, there is self centering effect, artificially the auxiliary claw head 55 of auxiliary claw 5 is closely pressed close to workpiece, claw base 51 inner chamber is shunk thus locked support member 53 by rotary moveable securing member 52, complete and the secondary of workpiece is clamped.
To those skilled in the art, obvious the utility model is not limited to the details of above-mentioned one exemplary embodiment, and when not deviating from spirit of the present utility model or essential characteristic, can realize the utility model in other specific forms.Therefore, no matter from which point, all should embodiment be regarded as exemplary, and be nonrestrictive, scope of the present utility model is limited by claims instead of above-mentioned explanation, and all changes be therefore intended in the implication of the equivalency by dropping on claim and scope are included in the utility model.Any Reference numeral in claim should be considered as the claim involved by limiting.
In addition, be to be understood that, although this description is described according to embodiment, but not each embodiment only comprises an independently technical scheme, this narrating mode of description is only for clarity sake, those skilled in the art should by description integrally, and the technical scheme in each embodiment also through appropriately combined, can form other embodiments that it will be appreciated by those skilled in the art that.
