Abstract
The utility model relates to a large-diameter fast locating nipple chuck used for a large-and-medium mechanical processing machine tool, which comprises a disk and a fixed axis arranged at the centre of the disk. A radial sliding chute is arranged on the disk; a jack catchs is arranged in the sliding chute. The large-diameter fast locating nipple chuck has the different points that: a linkage turntable is arranged at the back centre part of the disk; the linkage turntable is hinged with the back face of the jack catchs through the hinged connection rod; the linkage turntable is connected with a swing driving gear. The swing driving gear consists of a drive rod and a slide seat driving gear connected with each other, or both hinged ends of a pneumatic/hydraulic flow piston cylinder. The large-diameter fast locating nipple chuck has the advantages that: firstly, the jack catchs is of synchronous linkage not only with fast locating and clamping, but also with high locating precision, thereby realizing fast locating and clamping the large-diameter concentric jaw chuck; secondly, the clamping and disassembling of the large-diameter workpieces are simplified, and the operation is convenient; thirdly, the structure is simple and reasonable.
Description
Technical field
The utility model relates to a kind of major diameter that is used for big-and-middle-sized mechanical processing machine and locatees expansion chuck fast.
Background technology
Product parts must accurately be located and firm grip on lathe by certain technical requirements before carrying out machining.And for the circular product part, topmost clamping, locate mode are that centering clamps, and the anchor clamps that clamp that now are used to feel relieved are generally three-jaw or chuck.For three-jaw or the chuck of centering diameter below 500mm, claw generally all has interlock to clamp function, can realize the quick-clamping location to product parts.And three-jaw or the chuck of centering diameter more than 500mm, still the claw of being unrealized at present interlock, its centering mode also needs manually to beat the manual centering of table, complex operation and influenced by human factor bigger, particularly weight is heavier, and the location diameter is bigger, the product parts that positioning accuracy is high, more difficult assurance required precision, its location, clamping time are long, and operation easier is big.
Summary of the invention
Technical problem to be solved in the utility model is that the major diameter a kind of easy to operate, that the clamping time is short that provides at the deficiency of above-mentioned prior art existence is located expansion chuck fast.
The utility model is that the technical scheme that problem adopted of the above-mentioned existence of solution is: include disk 1 and the fixed axis 2 that is installed in the disk middle part, on disk, offer radial groove 4, be installed on claw 3 in the chute, its difference is to be installed on interlock rotating disk 6 at the middle part, the back side of disk, the interlock rotating disk is hinged by the back of hinged connecting rod 9 with claw, and described interlock rotating disk links to each other with the rotation drive unit.
Press such scheme, described rotation drive unit is joined by drive rod 11 and slide drive unit and constitutes; Perhaps moving piston cylinder two is hinged constitutes by gas/liquid.
Press such scheme, described slide drive unit comprises drive screw 12, drive screw and slide 13 phase configuration that have screw, and the upper end of slide and drive rod 11 are hinged.
Press such scheme, described claw is provided with 3～4, and along circumferentially uniform, each claw back links to each other with interlock rotating disk 6 by isometric connecting rod 9, so that each claw is made radially same moved further.
Press such scheme, described disk location diameter is φ 600mm～φ 1500mm.
The course of work of the present utility model is: by the rotating drive screw rod slide 13 is moved around, drive the 6 forward and reverse rotations of drive rod 11 push-and-pulls interlock rotating disk, the interlock rotating disk then drives the radially same back and forth moved further of chute of each claw by connecting rod 9, thereby realizes the quick location of workpiece is clamped.
The beneficial effects of the utility model are: (1) claw synchronous interaction, and not only the location clamps soon, and the positioning accuracy height, has realized that the quick location of major diameter self-centering chuck clamps; (2) clamping of large-diameter workpiece and dismounting are simplified, made things convenient for operation; (3) structure is provided with advantages of simple.
