Abstract

The present invention finishing cylindrical hydraulic tool chuck of generator amature, the frock chuck being related on a kind of lathe, including chuck body and three claws, claw is not positioned at the front end face of chuck body by guide rail, and claw can move along guide rail;It is coaxial into the axis hole for positioning generator amature, the axis hole and chuck body that three claws to the axis of chuck body draw close back wall;The axis hole is after three claws are drawn close to the axis of chuck body and mutually compressed, to be formed by turnery processing, and the diameter of the axis hole is smaller 0.01 ~ 0.1mm than the diameter of generator amature to be processed;In turnery processing axis hole, the rotating speed of chuck body is 140 ~ 160 revs/min.The hydraulic tool chuck structure of the present invention is simple and convenient to operate quick, clamping workpiece stabilization, accurate positioning, is effectively improved operating efficiency, reduces the labor intensity of worker and ensures the crudy of workpiece.

Description

Finish the cylindrical hydraulic tool chuck of generator amature
Technical field
The invention belongs to machining apparatus field, the frock chuck being related on a kind of lathe is more particularly to a kind of to process the cylindrical frock chuck of generator amature.
Background technology
In metal processing sectors, turning is a kind of conventional machining mode, is mainly used in working shaft-like part, and chuck is the mechanical device for being used for clamping workpiece on lathe, and workpiece is clamped by the claw positioning synchronous of chuck in turning process.The chuck of existing lathe uses three claws or four click-on mechanisms, and claw is rectangular parallelepiped structure, and oild chuck makees clamping work using the centripetal motion of hydraulic means driving claw, so as to which workpiece is positioned at into chuck hub;This installation way to coordinate requirement higher the claw of chuck in clamping process the problem of position inaccurate otherwise easily occur.Due to design defect, when being processed using existing frock chuck is cylindrical to generator amature, after being clamped by claw to generator amature, to ensure the precision in generator amature process, also need to lock the check and correction of claw one by one, ensure that the axial line of the axial line and chuck of generator amature is coaxial, said process is manually completed, labor strength is big, operating efficiency is low, it is not accurate to be also easy to occur correction center in clamping workpiece simultaneously, produces circular runout, influences the yield rate of work pieces process.
The content of the invention
It is an object of the invention to provide a kind of simple in construction, easy to operate, clamping workpiece stabilization, the cylindrical hydraulic tool chuck of finishing generator amature of accurate positioning.
The technical scheme that uses to achieve the above object of the present invention is:One kind finishing cylindrical hydraulic tool chuck of generator amature, including chuck body and three claws, claw is not positioned at the front end face of chuck body by guide rail, and claw can move along guide rail;Three claws draw close back wall into the axis hole for positioning generator amature to the axis of chuck body, the axis hole and chuck body are coaxial, the axis hole is after three claws are drawn close to the axis of chuck body and mutually compressed, formed by turnery processing, and the diameter of the axis hole is smaller 0.01 ~ 0.1mm than the diameter of generator amature to be processed.
Further technical scheme is the present invention:In turnery processing axis hole, the rotating speed of chuck body is 140 ~ 160 revs/min.
A kind of axis hole of the finishing cylindrical hydraulic tool chuck of generator amature of the present invention is different from traditional processing method:First three claws are drawn close to the axis of chuck body before axis hole is processed, and after mutually compressing, in-car hole operation is carried out to the claw mutually compressed by lathe again, so as to form axis hole, and when carrying out in-car hole operation, the speed of mainshaft of chuck body is 140 ~ 160 revs/min, and the axis hole so processed is high with chuck body concentricity;In addition, within shaft hole diameter of the invention is smaller 0.1mm than the diameter of generator amature to be processed, so after being clamped by claw to generator amature, be not required to lock claw check and correction one by one, ensure that the axial line of the axial line and chuck of generator amature is coaxial, to rotor it is cylindrical be processed during, rotor would not also produce circular runout, the labor intensity of worker is reduced, improves operating efficiency, ensures the crudy of workpiece.
The present invention finishing cylindrical hydraulic tool chuck of generator amature is further described with reference to the accompanying drawings and examples.
Brief description of the drawings
Fig. 1 is the structural representation of the present invention finishing cylindrical hydraulic tool chuck of generator amature;
Drawing reference numeral explanation:1- chuck bodies, 2- guide rails, 3- claws, 4- axis holes.
Embodiment
As shown in figure 1, a kind of finishing cylindrical hydraulic tool chuck of generator amature of the present invention, including chuck body 1 and three claws 3, claw 3 is not positioned at the front end face of chuck body 1 by guide rail 2, and claw 3 can move along guide rail 2;The axis of three claws 3 to chuck bodies 1 draws close back wall into the axis hole 4 for positioning generator amature, the axis hole 4 and chuck body 1 are coaxial, the axis hole 4 is after the axis of three claws 3 to chuck bodies 1 is drawn close and mutually compressed, formed by turnery processing, and the diameter of the axis hole 4 is smaller 0.01 ~ 0.1mm than the diameter of generator amature to be processed.
In turnery processing axis hole 4, the rotating speed of chuck body 1 is 140 ~ 160 revs/min.
Above example is only presently preferred embodiments of the present invention, and structure of the invention is not limited to the form that above-described embodiment is enumerated, and any modification for being made within the spirit and principles of the invention, equivalent substitution etc., be should be included in the scope of the protection.
