Abstract
The invention discloses a workpiece chuck. Clamping claws on the chunk move synchronously through an umbrella structure composed of connecting rods and a telescopic device. Compared with a traditional chunk with a spiral clamping mode, the workpiece chuck has fewer errors and better synchronization, and clamping force can be adjusted very conveniently through adjustment on the telescopic device. Compared with a traditional rotating type clamping mode, the workpiece chuck is more rapid and accurate in opening and clamping.
Description
Technical field
The present invention relates to a kind of workpiece chuck, belong to field of machining.
Background technology
Traditional drilling machine, horizontal milling machine is all to realize fastening to workpiece by bench vice, but this clamping mode position degree is poor, and the stability clamped is also bad, and traditional three-pawl type chuck is by the clamping that screws of screw thread, after long-time the use, its position degree that clamps rear workpiece also can't guarantee.
Summary of the invention
The object of the invention is to: a kind of technical scheme that can address the above problem is provided.
The present invention realizes by the following method:
A kind of workpiece chuck, comprise some chucking claws, the guide rail identical with chucking claw quantity, chuck body, described guide rail points to the chuck body center array and arranges, described chucking claw by guide rails assembling in chuck body, described chuck also comprises connecting rod base, retractor device, the connecting rod that quantity is identical with chucking claw, the bottom of described connecting rod one end and chucking claw is rotationally connected, the connecting rod other end and connecting rod base are rotationally connected, described connecting rod base is suspended in the chuck body bottom, one end of described connecting rod base and retractor device is connected, the start direction of described retractor device is perpendicular to the chuck body plane, the other end of described retractor device is connected with chuck body bottom or frame.
As further innovation of the present invention, described chucking claw bottom is provided be used to snapping in the protruding key of guide rail, described chucking claw projection key is provided with half-cylindrical projection towards the one side of chuck body middle position, and the axis of described semicolumn is vertical with the chuck body bottom surface.
As further innovation of the present invention, on described protruding key, be provided with the groove of some rules with the guide rail contact-making surface.
Beneficial effect
Beneficial effect of the present invention is:
1. the present invention is by connecting rod, retractor device, structure with a umbrella realizes the synchronizing moving to chucking claw on chuck, chuck than traditional screw type clamping, of the present invention have lower error and better synchronously spend, by the adjustment to retractor device, clamping force also can be adjusted very easily, and opens and clamp more traditional rotary clamping mode more rapidly with accurate.
2. the present invention is by the chucking claw head, semicircular jacking block being set, to prevent when there is no clamping workpiece, because the clamping of chucking claw causes connecting rod and the retractor device that the excessive movement of telescoping mechanism causes to bump and be damaged.
3. the present invention arranges some grooves by the contact-making surface at protruding key and guide rail, and lubricating oil can be stored in inside grooves, realizes lubricated effect, to guarantee can or not because of long-term the use, not produce wearing and tearing by chucking claw, causes the reduction of precision.
The accompanying drawing explanation
Fig. 1 is that structure of the present invention is always schemed.
Fig. 2 is the top view of chuck of the present invention.
Fig. 3 is the side view of chucking claw of the present invention.
Fig. 4 is the top view of chucking claw of the present invention.
In figure: 1, chucking claw; 2, connecting rod; 3, connecting rod base; 4, retractor device; 5, chuck body; 6, groove; 7, frame; 8, guide rail.
The specific embodiment
Below in conjunction with accompanying drawing, be described further
As shown in Fig. 1 ~ 4, a kind of workpiece chuck, comprise some chucking claws 1, the guide rail 8 identical with chucking claw 1 quantity, chuck body 5, described guide rail 8 points to chuck body 5 center array and arranges, described chucking claw 1 is installed in chuck body 5 by guide rail 8, described chuck also comprises connecting rod base 3, retractor device 4, the connecting rod 2 that quantity is identical with chucking claw 1, the bottom of described connecting rod 2 one ends and chucking claw 1 is rotationally connected, connecting rod 2 other ends and connecting rod base 3 are rotationally connected, described connecting rod base 3 is suspended in the chuck bottom, one end of described connecting rod base 3 and retractor device 4 is connected, the start direction of described retractor device 4 is perpendicular to chuck body 5 planes, the other end of described retractor device 4 is connected with chuck bottom or frame 7,
Described chucking claw 1 bottom is provided be used to snapping in the protruding key of guide rail 8, and the protruding key of described chucking claw 1 is provided with half-cylindrical projection towards the one side of chuck body 5 middle positions, and the axis of described semicolumn is vertical with chuck body 5 bottom surfaces;
On described protruding key, be provided with the groove 6 of some rules with guide rail 8 contact-making surfaces.
In use, at first make retractor device, in the present embodiment, use pneumaticpiston, described pneumaticpiston one end is arranged on the frame bottom.Make it inflated elongation, thereby chucking claw is expanded outwardly along guide rail, and now chuck unclamps, by workpiece setting in the middle of chuck, afterwards pneumaticpiston is bled, make it to shorten, because now workpiece is because the synchronizing moving of chuck chucking claw is stepped up to hit exactly at chuck automatically, by the adjustment to vacuum in piston, can according to the material of workpiece, adjust the dynamics of clamping, after workpiece is clamped, can process it.
Claims (3)
1. workpiece chuck, comprise some chucking claws, the guide rail identical with chucking claw quantity, chuck body, described guide rail points to the chuck body center array and arranges, described chucking claw by guide rails assembling in chuck body, it is characterized in that: described chuck body also comprises connecting rod base, retractor device, the connecting rod that quantity is identical with chucking claw, the bottom of described connecting rod one end and chucking claw is rotationally connected, the connecting rod other end and connecting rod base are rotationally connected, described connecting rod base is suspended in the chuck body bottom, one end of described connecting rod base and retractor device is connected, the start direction of described retractor device is perpendicular to the chuck plane, the other end of described retractor device is connected with chuck body bottom or frame.
