Abstract
The utility model relates to a turning device for elliptic work pieces, which is composed of a tube seat, an eccentric pin seat, a sliding block, a sliding plate and a locating and clamping mechanism for work pieces; the eccentric pin seat is arranged in the inner hole of the tube seat, and the sliding block is pressed on the eccentric pin seat by a pin and a bearing; the sliding block rotates along the tube seat and simultaneously pushes the sliding plate in a cross dovetail groove to rotate to drive the work piece to changeably rotate with the divergence from the center of the main shaft of a lathe; cutters are fed one time, the forming and turning of the outer surface of an ellipse can be completed to imitate and turn; the lathe mechanism is not needed to change, the geometry shape quality and requirement can be ensured by the utility model, and the utility model has the advantages of simple structure, convenient operation, low noise and high work efficiency.
Description
The utility model relates to the Machining Technology field, specifically a kind of oval workpiece turning clamp.
At present, the processing of oval workpiece is adopted increases a cam on lathe spindle, lay down the length feed leading screw of lathe feed arrangement, connect knife rest with connecting rod, workpiece and cam rotate synchronously in turning process, cutter is reciprocating and reach the purpose of turning by cam control, this processing method is vibrated in process greatly, the noise height, and surface roughness requires to be difficult for guaranteeing, operation inconvenience, and because the error in geometrical form of cam directly has influence on the crudy of workpiece.
The purpose of this utility model is the deficiency that overcomes in the present oval workpiece turning, provides a kind of and need not change machine tool structure, and friction in the working angles, noise is low, and the surface roughness height can keep the workpiece crudy, the oval workpiece truning fixture that work efficiency is high.
The utility model is to realize like this, this oval workpiece truning fixture, mainly by ring flange, work piece positioning tightly installs formation, it is characterized in that ring flange is fastened on the lathe spindle, one end of pull bar is fastened on the headstock end by the lathe spindle hole, the other end is connected on the eccentric key seat that places the ring flange endoporus with pin, slide block is by pin, bearing is pressed on the eccentric key seat, and slidably reciprocates in the dovetail groove of slide plate, and the positioning and clamping mechanism of workpiece is by bolt, nut, packing ring, the cover plate seat is formed, the cover plate seat is connected with bolt with slide plate, and ring flange adopts dovetail groove to be connected with cover plate.
The offset of the eccentric key seat centering heart is the semi-minor axis that the major semiaxis of oval workpiece deducts oval workpiece.
Dovetail groove on the slide plate is a cross.
The utility model is through trial-production and trial run, and the workpiece geometries that car goes out is accurate, meets the drawing requirement of product fully, has easy and simple to handlely, need not change lathe mechanism, and friction easily prolongs cutter life, guarantees workpiece surface roughness, the work efficiency advantages of higher.
Now in conjunction with the accompanying drawings embodiment of the present utility model is illustrated.
Accompanying drawing 1 is the front view of the utility model embodiment.
Accompanying drawing 2 is the left view after accompanying drawing 1 removes workpiece positioning clamping mechanism.
In the accompanying drawing: 1. pull bar 2. garden taper pins 3. ring flanges 4. eccentric key seats
5,6. bearing 7. slide blocks 8. pins 9. slide plates
10. cover plate seat 11. workpiece 12. packing rings 13. nuts
14. bolt 15. cross dovetail grooves
In the drawings, when lathe spindle rotates, when slide block 7 rotates with ring flange 3, promoting slide plate 9 in cross dovetail groove 15 rotates, slide plate drives cover plate seat 10, workpiece 11, bolt 14, nut 13, packing ring 12 rotations, rotates because slide block 7 promotes slide plate 9 in cross dovetail groove 15, and workpiece 11 departs from the lathe spindle center and changes rotation, the cutter positioning feeding once can be finished the elliptic curve copying.
Claims (3)
