Abstract
The utility model relates to a multipurpose mechanical chuck which comprises a chuck body and three or four jaws, wherein, the jaws are symmetrically and movably installed on the chuck body, the chuck body is fixedly provided with a supporting disc through a screw, a plurality of threaded rods, a plurality of self-centering sliding blocks and a disc spiral gear wheel are movably installed through the supporting disc, the number of the threaded rods and the self-centering sliding blocks is equal to that of the jaws, each jaw is respectively connected with one threaded rod and one self-centering sliding block, the threaded rods are installed in the self-centering sliding blocks, all the self-centering sliding blocks are connected with gears on the disc spiral gear wheel, an olive-shape gear is installed on the supporting disc, the olive-shape gear is meshed with the gears on the disc spiral gear wheel, hexagonal holes are formed on the threaded rod, and square head holes are formed on the olive-shape gear. The utility model integrates the three-jaw self-centering chuck and the four-jaw independent chuck into a whole, is suitable for processing steady batch parts with various geometrical shapes, has reasonable design, simplifies the replacement of the three-jaw self-centering chuck and the four-jaw independent chuck, saves a great amount of labor force, saves the expends, increases the benefits and simplifies the process.
Description
Technical field
The utility model relates to a kind of multi-purpose machinery chuck.
Background technology
In mechanical processing process, workpiece is subjected to the effect of cutting force, centrifugal force, inertia force etc., in order to guarantee under these external force effects, workpiece still can keep the Working position determined by setting element in anchor clamps, and in unlikely generation vibration or displacement, the clamp structure clamping device should be set workpiece is reliably clipped.
When the workpiece machined surface when being the operation benchmark, for making datum coincidence to reduce position error, needs to adopt centering and clamping mechanism with center key element (axis, central plane etc.).
Centering and clamping mechanism has centering and clamps two kinds of functions, is the most frequently used representative instance as the three-jaw self-centering chuck of horizontal lathe.
With chuck three-jaw self-centering chuck and four-jaw chuck are arranged now, the claw of three-jaw self-centering chuck is mainly used in the chucking cylindrical work with advancing with going out, and the claw list of four-jaw chuck advances singly, and is mainly used in the prismatic workpiece of chucking.And do not have a kind of collection three jaw self-centerings and four paws single action is the chuck of one, needs three in use, chuck changes, very trouble.
The utility model content
The utility model technical issues that need to address just are to overcome the defective of prior art, a kind of multi-functional chuck is provided, it collects three jaw self-centerings and the four paws single action is an one, simplified the same geometry workpiece repeat to proofread and correct with three, the replacing of chuck, when saving a large amount of labours, save expense, increased benefit, simplified technology.
For addressing the above problem, the utility model adopts following technical scheme: the utility model multi-purpose machinery chuck, comprise chuck body and a plurality of claw, claw is movably arranged on the chuck body symmetrically, chuck body is set with supporting disk by screw, be movably installed with a plurality of screw rods by supporting disk, a plurality of self-centering slide blocks and a butterfly helical tooth wheel disc, the quantity of screw rod and self-centering slide block and the quantity of claw equate, each claw is connected with a screw rod and a self-centering slide block respectively, screw rod is installed in the self-centering slide block, all self-centering slide blocks all are connected with butterfly helical tooth wheel disc, the olive-type gear is installed, the gears engaged on olive-type gear and the butterfly helical tooth wheel disc on the supporting disk.Claw described in the utility model is three or four.Screw rod described in the utility model is provided with hexagon ring, and described olive-type gear is provided with the square toes hole.
The utility model chuck disposes the cross double (end) wrench, and described double end is respectively turret head and square toes.
Use of the present utility model is:
Adjust screw rod with the cross like spanner turret head, make respectively and move on the claw or move down, claw is realized singly advancing singly, and is the center until adjusting workpiece.
Use the square spanner clamping work pieces, make the olive-type gear do rotation, drive the butterfly rotation roulette and do the plane and rotate, drive self-centering slide block, screw rod, claw simultaneously and move or move clamping work pieces outward in doing, claw is with advancing with going out, clamp to be that self-centering, workpiece enter to add the duration.
The utility model chuck collection three jaw self-centerings and four paws single action are one, be applicable to the part processing of various geometries with certain batch, after one time single action is proofreaied and correct completion of processing, clamping workpiece can be used self-centering mechanism once more, clamping work pieces apace, enter second then, until process finishing.
The utility model chuck design is reasonable, in operating process without any need for any special measures, it simplified waste time and energy three, the replacing of chuck, when saving a large amount of labours, saved certain expense, increased benefit, simplified technology.
