Technical field
The invention belongs to field of machining, in particular to a kind of Automobile Part list handle Machining of Connecting Rod lathe that is applied to is used
Turning attachment.
Background technique
For the lathe process sequence of Automobile Part list handle connecting rod, main processing content is face work, interior hole, cuts
Slot, processing diameter of bore and its circularity in drawing is special characteristics size, and assembly success or not is played in the assembly in later period
Effect, we in common processing only be common three-jaw, but after carrying out interior hole machined with common three-jaw, be easy to appear interior
Diameter and circularity off-dimension, it is predominantly unqualified caused by deformation.
Summary of the invention
Technical problem solved by the invention is to be to provide a kind of completely new turning attachment, can effectively eliminate Automobile Part
In single handle connecting rod lathe process the problem of inner hole machining deformation.
The technology used in the present invention means are as described below.
A kind of turning attachment of Automobile Part list handle connecting rod, is used to process connecting rod, which has circular portion
With shank connected to it, it includes more than two clamping jaws for stepping up connecting rod, which is movably connected on cup dolly；
Clamping jaw is rectangular parallelepiped structure, is vertically arranged along cup dolly diameter to the center of circle, clamping jaw offers longitudinal close to center of circle one end
Accommodation groove, the longitudinally disposed connecting plate of the interior accommodating of accommodation groove, connecting plate centre is equipped with lateral direction penetrating hole, clamping jaw and the through hole
Aperture is arranged in corresponding position two sides, and aperture is with accommodating connecting pin in through hole connecting plate to be fixedly connected with clamping jaw；Connecting plate
Two sides offer accommodating hole above and below through hole, and Universal clamp head is inserted in accommodating hole；Cup dolly, which is provided centrally with, to be used for
The positioning end cap of positioning link bar；Cup dolly is additionally provided with several clump weights.
Clamping jaw is three, and clump weight is four pieces.
The universal collet has fixed link, fixed link one end connecting clip nut, and chuck nut is connect another with fixed link
Side is rough surface.
The positioning end cap is round and is fixed by positioning pin and cup dolly；Upwards several fixed is arranged in the positioning end cap
Position wall, the positionable wall match with connecting rod front end circular portion.
Technical effect caused by the present invention is as follows：Clamping connecting rod circle is distinguished by the clamping of three groups of two general-purpose collets
Two blank outer circles up and down of shape part outer circle blank, and dispersion principle 6Kg is firmly learned with there are four clump weight on chuck
Chuck pressure, eliminate processing in the problem on deformation of internal diameter and circularity.This not only improves product in process
Stability, also to the irregular workpiece of later period lathe process have directive significance.It increases the efficiency of the manufacturing and reduces
The undesirable risk of quality.Solves the problems, such as the Internal Hole Deformation due to caused by clamping in Automobile Part connecting rod manufacturing procedure.
Detailed description of the invention
Fig. 1 is turning attachment schematic perspective view of the invention.
Fig. 2 is turning attachment overlooking structure diagram of the invention.
Fig. 3 is universal collet schematic perspective view of the invention.
Specific embodiment
As shown in Figures 1 and 2, a kind of turning attachment of Automobile Part list handle connecting rod of the present invention, is used to process connecting rod
A, connecting rod A have circular portion A1 and shank A2 connected to it.It includes more than two folders for stepping up connecting rod A
Pawl 1 is in the present embodiment three clamping jaws, is optimal selection.The clamping jaw 1 is movably connected on cup dolly 2；This flexible connection
It is that those skilled in the art are easy to accomplish, details are not described herein, for example, it may be being provided with track, clamping jaw in disc base
Bottom setting is fluted, and clamping jaw is provided with fixing screws, unclamps screw when needing mobile, slides, need fixed in orbit
Screw is tightened, is also possible to be equipped with multiple holes using disc base, clamping jaw is equipped with to be inserted with the matched protrusion in hole, foundation locational requirement
Enter corresponding aperture, be also possible to Electronic control component, is ok as long as being able to achieve correlation function.
Clamping jaw 1 is rectangular parallelepiped structure, is vertically arranged along 2 diameter of cup dolly to the center of circle, clamping jaw 1 is opened close to center of circle one end
Equipped with longitudinal accommodation groove 11, longitudinally disposed connecting plate 3 is accommodated in accommodation groove 11, is equipped with lateral direction penetrating among the connecting plate 3
Hole（It is not marked in figure）, clamping jaw 1 and the through hole corresponding position two sides are arranged aperture, accommodate connecting pin 4 in aperture and through hole
Connecting plate 3 to be fixedly connected with clamping jaw 1；For fix stably, the top of clamping jaw 1 can also be provided with bolt 12, bolt
Positioned at connecting plate two sides, to play further firm effect.Connecting plate 3 is located at through hole and offers accommodating hole in two sides up and down,
Universal clamp head 5 is inserted in accommodating hole；In the present embodiment, which has fixed link 51, and fixed link is inserted and fixed to
Accommodating hole, 51 one end connecting clip nut 52 of fixed link, the other side that chuck nut 52 is connect with fixed link 51 are rough surface, should
Rough surface can be arranged according to demand, as shown in figure 3, the rough surface is similar continuous upward triangle.Here circle
Pedestal can be solid 10 cun of oild chucks, and clamping jaw is for stepping up and unclamping workpiece（Connecting rod）, and utilize connecting plate and universal
