Description

A kind of turnery processing special fixture
Technical field
This utility model belongs to machining equipment technical field, relates to a kind of turnery processing special fixture.
Background technology
Lathe process is the some of machining.Lathe process mainly carries out turnery processing with lathe tool to the workpiece rotated.Lathe can also be used with drill bit, reamer, reamer, screw tap, screw die and checkering tool etc. process accordingly.Lathe be mainly used in processing axle, dish, set and other there is the workpiece of rotary surface, be that machine-building and repair factory use a widest class machine tooling.
Workpiece rotates, and the machining of straight line or curve movement planar made by lathe tool.Turning is typically carried out on lathe, in order to process inside and outside circle cylinder, end face, taper seat, forming face and the screw thread etc. of workpiece.During turning inside and outside circle cylinder, lathe tool moves along the direction being parallel to workpiece rotation axis.When turning end or cut-out workpiece, lathe tool is along the direction horizontal movement being perpendicular to workpiece rotation axis.If the movement locus of lathe tool becomes an oblique angle with workpiece rotation axis, taper seat just can be processed.The revolving body surface that turning shapes, can use forming-tool general laws or point of a knife method of loci.During turning, workpiece is rotated primary movement by machine tool chief axis;Feed motion made by the lathe tool being clamped on knife rest.
Various frock clamps are applied widely in mechanical manufacturing field; due in lathe operation; workpiece must be clamped and just can be processed; traditional fixture is typically all scroll chuck, only three claws, three stress points; and these three stress point is in one plane; therefore can only clamp the workpiece with symmetrical structure, clamping not strongly often occurs in the workpiece for abnormity, the situation that workpiece drops.The utility model patent of Application No. 201520234587.2 discloses a kind of turning attachment, including " u "-shaped fixed mount, lathe clamping part, the first supporting rod, fixed slip bar, fixed disk and the second supporting rod.Two fixed disks of turning attachment are equivalent to two claws, three the second supporting rods are had on each fixed disk, during clamping workpiece, six stress points can be provided, and stress point is not or not a plane, is distributed in the space of three-dimensional, for special-shaped asymmetric workpiece, can clamp according to the depth position that each position of workpiece is different, uniform force, fixation will not fall off.
But, when workpiece being clamped by six stress points, it is impossible to effectively ensure that six stress points all act on workpiece, thus this turning attachment is relatively low to the clamping effect of workpiece.Additionally, workpiece is clamped by existing turning attachment generally by three claws, various sizes of workpiece is clamped by three removable realizations of claw;Three stress points act on workpiece, and workpiece is less with the application point of fixture, the force limited between fixture and workpiece so that fixture is relatively low to the clamping effect of workpiece.
