Abstract
The invention relates to a machining method for a square work-piece. According to the machining method, a three-jaw chuck is used for machining the square work-piece and the three-jaw chuck comprises a chuck body, three movable jaws and a jaw drive mechanism. The specific machining method comprises the following steps of: (1) cutting the parts (abutting against the work-piece) of the three jaws of the three-jaw chuck so that the surface composed of the tops of the three movable jaws is similar to the cross section of the machined work-piece in shape; and (2) further adjusting the jaw drive mechanism on the basis that the surface composed of the tops of the three movable jaws is similar to the cross section of the machined work-piece in shape in the step (1), so that the surface composed of the tops of the three movable jaws is superposed with the cross section of the work-piece, thus fixing the machined work-piece. According to the machining method for a square work-piece disclosed by the invention, the three processed movable jaws are used, and the section composed of the tops of the three jaws is superposed with the cross section of the work-piece under the action of the jaw drive mechanism, thus fixing the machined work-piece; moreover, the machining method for a square work-piece is simple in structure, convenient in operation, and low in cost.
Description
Technical field
the invention belongs to field of machining, particularly a kind of processing method of side's body workpiece.
Background technology
are present, are used for surface of the work processing, generally all adopt three-jaw or chuck to clamp workpiece to be processed, carry out the processing of sequencing then; Workpiece (cylinder) for rule adopts scroll chuck to fix, and is as shown in Figure 1, according to scroll chuck 1 ' self-centering action, under the claw driving mechanism; The claw 4 of three activities ' along chuck body 3 ' on draw-in groove 30 ' move to chuck hub, by scroll chuck 1 ' self-centering action, give fixedly bringing convenience of workpiece; Yet, be not that all processing works all are the cylinder of rule, as shown in Figure 2; The square body of rule processing in the actual life, then adopt chuck 2 ', according to chuck 2 ' the claw 4 ' relative independentability of four activities; The claw 4 of four activities ' the driving mechanism effect under, the claw 4 of four activities ' along chuck body 3 ' on draw-in groove 30 ' move four surfaces of the side's of acting directly on body respectively to chuck hub; Thereby reach the stability of workpiece processing, however adopt chuck 2 ' be not easy the to confirm center of workpiece, the processing of general side's body workpiece be adopt earlier chuck 2 '; One end of workpiece is processed into cylindrical, adopts cylindrical after scroll chuck 1 ' the clamp processing again, carry out the processing in a dark step; Therefore, in the processing of square body workpiece, the process more complicated; The efficient of processing is not high, and the processed workpiece accuracy is lower, and cost is also bigger simultaneously.
Summary of the invention
technical problem to be solved by this invention is the deficiency that overcomes prior art, a kind of processing method of side's body workpiece is provided, particularly a kind of improved scroll chuck.
For solving above technical problem, a kind of technical scheme that the present invention takes is:
A kind of processing method of side's body workpiece, what this processing method adopted is the processing of the scroll chuck side of carrying out body workpiece, wherein scroll chuck comprises the claw and the claw driving mechanism of chuck body, three activities, concrete processing as follows:
(1), three claw conflict workpiece of scroll chuck are partly carried out cutting process, the face that makes the claw top of three activities constitute is similar with the shape of the cross section of processing work;
(2), the face that is made up of the claw top of three activities described in the step (1) are similar with the shape of the cross section of processing work; Further regulate the claw driving mechanism; The face that makes the claw top of three activities constitute overlaps with the cross section of workpiece; Thereby fixed the workpiece of processing, conveniently carried out next step processing.
Because the employing of technique scheme, the present invention compared with prior art has the following advantages:
the present invention adopts three movable jaws after treatment similar with the shape of cross section of workpiece; Under the effect of claw driving mechanism; The cross section that makes the top of three claws constitute overlaps with the cross section of workpiece, thereby has fixed the workpiece of processing, and it is simple in structure; Easy to operate, cost is lower.
Description of drawings
are done further detailed explanation below in conjunction with accompanying drawing and concrete embodiment to the present invention.
Fig. 1 looks sketch map for the master of scroll chuck fixation workpiece in the original technology of the present invention;
Fig. 2 looks sketch map for the master of chuck fixation workpiece in the original technology of the present invention;
Fig. 3 looks sketch map for the master of the scroll chuck fixation workpiece of the present invention after improving;
wherein: 1,1 ' scroll chuck; 2,2 ' chuck; 3,3 ' chuck body; 30,30 ' draw-in groove; 4,4 claws; 5, workpiece.
The specific embodiment
As shown in Figure 3; Processing method according to a kind of side's body of present embodiment workpiece; What this processing method adopted is the processing of scroll chuck 1 side's of carrying out body workpiece 5, and wherein scroll chuck 1 comprises the claw 4 and the claw driving mechanism (not shown) of chuck body 3, three activities, concrete processing as follows:
(1), three claws, the 4 conflict workpiece of scroll chuck 1 are partly carried out cutting process, the face that makes claw 4 tops of three activities constitute is similar with the shape of the cross section of processing work;
(2), the face that is made up of claw 4 tops of three activities described in the step (1) are similar with the shape of the cross section of processing work 5; Further regulate the claw driving mechanism; The face that makes claw 4 tops of three activities constitute overlaps with the cross section of workpiece 5; Thereby fixed the workpiece 5 of processing, conveniently carried out next step processing.
are similar with the shape of cross section of workpiece by three movable jaws after handling, and under the effect of claw driving mechanism, make the cross section of top formation of three claws overlap with the cross section of workpiece; Thereby fixed the workpiece of processing; Compared with prior art, solved scroll chuck can not the side of processing body workpiece and chuck be difficult to confirm the problem of workpiece centre, it is simple in structure; Easy to operate, cost is lower.
More than the present invention has been done detailed description; Its purpose is to let the personage that is familiar with this art can understand content of the present invention and implements; Can not limit protection scope of the present invention with this; All equivalences of doing according to spirit of the present invention change or modify, and all should be encompassed in protection scope of the present invention
