Abstract
The utility model provides a novel chuck jaw and belongs to the technical field of machines. The novel chuck jaw solves the problem that an existing chuck jaw is insecure in clamping. The novel chuck jaw comprises a chuck base, a clamping jaw is fixedly connected to the base, and the clamping jaw is provided with a plurality of cambered clamping portions which are distributed in parallel. Detachable connection is adopted in the novel chuck jaw, the novel chuck jaw is convenient to disassemble and maintain, the clamping portions of the chuck jaw are cambered and can limit movement of workpieces in the rotation direction and further generate certain clamping force in the radial direction, and therefore the novel chuck jaw has the advantages of being stable in clamping and convenient to maintain.
Description
Technical field
The utility model belongs to field of mechanical technique, relates to a kind of clamping tooling, particularly a kind of chuck jaw.
Background technology
In machining, at first need workpiece to be processed is carried out to clamping position, workpiece on lathe location adopts the chuck be fixed on main shaft to carry out clamping, and the workpiece of clamping mostly is revolving body, and revolving body needs high speed rotating man-hour adding, therefore very high to the stability requirement of piece-holder, especially for some large-scale workpieces, after its clamping, because position to be processed is longer, it is shorter that position is accepted in clamping, cause easily causing workpiece to rock, make the workpiece of processing produce run-out tolerance.
Current lathe chuck generally adopts scroll chuck, chuck etc., it adopts three or four chuck jaws to be fixed on main shaft, chuck jaw generally adopts the straight line step, as shown in Chinese patent (Granted publication CN201815690U), during its holding workpiece, the step of chuck jaw contacts with the outer surface of part, now, chuck jaw is line contact or even some contact with contacting of workpiece, its contact-making surface is little, the clamping jail is insecure, is difficult to especially effective clamping for shaggy blank in addition.
Summary of the invention
The purpose of this utility model is to have the problems referred to above for existing technology, has proposed the chuck jaw that a kind of clamping stability is high.
The purpose of this utility model can realize by following technical proposal: a kind of Novel chuck pawl, comprise the chuck pedestal, and it is characterized in that, be fixedly connected with claw on described pedestal, there is the curved clamping part of several parallel distributions on described claw.
In above-mentioned Novel chuck pawl, the described claw back side is provided with bolt hole, and described chuck pedestal is provided with counter sink, and described chuck pedestal passes counter sink by bolt and is connected with the bolt hole at the claw back side.
In above-mentioned Novel chuck pawl, described chuck pedestal outer face is curved.The chuck pedestal is installed in chuck body, and several chuck pedestals and chuck body form a uniform cylindrical, while preventing that main shaft from rotating because crank shakes.
Compared with prior art, this chuck jaw adopts and to removably connect, for convenience detach and maintenance of chuck jaw, the clamping part of chuck jaw is arc, not only on rotation direction, limits workpiece motion s, is also producing in the radial direction certain chucking power, there is clamping firm, advantage easy to maintenance.
The accompanying drawing explanation
Fig. 1 is the front axonometric drawing of this Novel chuck pawl;
Fig. 2 is the back side axonometric drawing of this Novel chuck pawl.
In figure, 1, the chuck pedestal; 2, claw; 3, clamping part; 4, counter sink.
The specific embodiment
Be below specific embodiment of the utility model by reference to the accompanying drawings, the technical solution of the utility model is further described, but the utility model be not limited to these embodiment.
As depicted in figs. 1 and 2, this Novel chuck pawl comprises chuck pedestal 1, is fixedly connected with claw 2 on pedestal 1, has the curved clamping part 3 of several parallel distributions on claw 2.Chuck pedestal 1 is provided with counter sink 4, and claw 2 back sides are provided with bolt hole, and chuck pedestal 1 is provided with and can passes counter sink 4 and the bolt that claw 2 back side bolts hole are connected, and by this bolt, chuck pedestal 1 is fixedly connected with claw 2.Chuck pedestal 1 outer face is curved.
This chuck jaw is installed in the chuck body of scroll chuck, three chuck jaws embed respectively in chuck body, because the chuck body outside is curved, chuck pedestal 1 outside of three chuck jaws is also curved, form a circle after chuck jaw and chuck body successful installation, in the time of can effectively preventing that main shaft from rotating because crank shakes.Chuck jaw is when holding workpiece, and because clamping part 3 is curved, claw 2 both can limit the circumferential rotation of workpiece, can also limit the motion of workpiece radial direction, had effectively guaranteed piece-holder stability.
Specific embodiment described herein is only to the explanation for example of the utility model spirit.The utility model person of ordinary skill in the field can make various modifications or supplements or adopt similar mode to substitute described specific embodiment, but can't depart from spirit of the present utility model or surmount the defined scope of appended claims.
Claims (4)
