Description

A kind of turning attachment
[technical field]
The utility model belongs to Machining Technology field, is specifically related to a kind of turning attachment.
[background technology]
In Machining Technology, requiring very high to the clamping of workpiece, three chucks generally using carry out clamping, for axle Class finding clamping preferably deforms and time-consuming, so relatively low to productivity ratio in Machining Technology, at present, based on hand-operated clamping, Clamping process is that manual operation, clamping are safe and reliable not, more complicated, thus causes that working (machining) efficiency is low, machining accuracy is low, holds Easily causing cosmetic injury, the labour intensity of operating personnel increases, and the production cycle extends, and in order to save production cost, improves and produces Benefit, cylinder is arranged on clamp body by existing air-actuated jaw, and air inlet outlet passageway exposes, and structure imperfection easily causes safety Hidden danger.
[content of the invention]
Technical problem to be solved in the utility model is for above-mentioned deficiency of the prior art, provides a kind of pneumatic Turning attachment, clamps workpiece under not parking state, it is to avoid lathe frequent starting, reduces equipment loss.
The utility model is by the following technical solutions:
A kind of turning attachment, including band step dish class formation clamp body, fixture body disc overcoat is equipped with round buss, inclined-plane lining And cylinder seat, it is provided with back-moving spring and collet on the right side of clamp body, on the left of clamp body, be provided with circular pull bar, circular pull bar Passing on left spindle hole to be connected with cylinder piston rod, right side fastens through conical seat, and conical seat is connected with the lower end of double inclined plane bar, The upper end of double inclined plane bar is connected with inclined-plane lining through round buss, can drive round buss axially-movable, set successively on the right side of cylinder seat Being equipped with double-direction thrust ball bearing and tapered collet, collet is connected with acoustic-optic alarm.
Further, circular pull bar and circular seat form relocation mechanism.
Further, clamp body and collet rotate with main shaft, and cylinder seat does not turns.
Further, conical seat and double inclined plane bar contact surface are wedge shape, and double inclined plane bar can outwardly or inwardly do radially fortune simultaneously Dynamic.
Further, double inclined plane bar includes two groups, often organizes and is provided with spring on double inclined plane bar.
Compared with prior art, the utility model at least has the advantages that and avoids lathe frequent start-stop, and reduction sets Standby loss;Utilize source of the gas Automatic-clamping and unclamp workpiece, easy to operate, improve production efficiency;Utilize collet automatic centering Be installed part;Utilize rearmounted cylinders providing power, replace manual operations, it is achieved clamping under not parking state, use circular pull bar " floating " mode, make machining accuracy significantly improve, and add job stability, this clamp structure is compact, general adjustable, is A kind of efficient, safe Green Machining corollary apparatus, it is adaptable to the not parking processing of axial workpiece on numerically controlled lathe and engine lathe.
[brief description]
Fig. 1 is structural representation of the present utility model.
Wherein: 1. clamp body;2. round buss;3. inclined-plane lining;4. back-moving spring;5. collet;6. circular pull bar;7. Conical seat;8. double inclined plane bar;9. cylinder seat;10. double-direction thrust ball bearing;11. tapered collet;12. circular seat;13. lathe tails Seat;14. workpiece.
[detailed description of the invention]
Referring to shown in Fig. 1, the utility model provides a kind of turning attachment, including clamp body 1, clamp body 1 is band platform Rank dish class formation, is connected with main shaft;It is set with round buss the 2nd, inclined-plane lining 3 and cylinder seat 9, clamp body 1 right-hand member outside clamp body 1 dish It is provided with back-moving spring 4 and collet 5, on the right side of cylinder seat 9, be disposed with cushion cover, double-direction thrust ball bearing the 10th, conically shaped Folder the 11st, back-up ring, the inner conical surface of tapered collet 11 matches with the profile of collet 5, and collet 5 is connected with sound and light alarm dress Put, sound and light alarm can be carried out.
Being provided with circular pull bar 6 on the left of clamp body 1, circular pull bar 6 left end is connected with cylinder piston rod by spindle hole, right Side is fastened by nut after penetrating conical seat 7, and conical seat 7 is connected with the lower end of double inclined plane bar 8, and the upper end of double inclined plane bar 8 is passed through Round buss 2 is connected with described inclined-plane lining 3, composition radially driving-chain, can drive round buss 2 axially-movable, and double inclined plane bar 8 can be same When outwardly or inwardly do radial motion, double inclined plane bar 8 includes two groups, often organizes and is provided with spring on described double inclined plane bar 8.
When rearmounted cylinder action, circular seat the 12nd, circular pull bar 6 and lower end conical seat 7 is driven to move, due to lower end toper Seat 7 and double inclined plane bar 8 contact surface are wedge shape, and two groups of double inclined plane bars 8 can outwardly or inwardly do radial motion simultaneously, its outer end with tiltedly Face lining 3 contacts, and promotes inclined-plane lining 3 and cylinder seat 9 to move in the axial direction, and then by the axially-movable of tapered collet 11 Realize the pine folder of collet 5.
Under not parking state, clamp body 1 and collet 5 rotate with main shaft, and cylinder seat 9 does not turns.Workpiece 14 cylindrical one End loads in collet 5, and tailstock tool 13 thimble coordinates positioning.Starting source of the gas, making circular pull bar 6 move to left, conical seat 7 forces Double inclined plane bar 8 moves radially outwards, and drives inclined-plane lining the 3rd, cylinder seat 9 and tapered collet 11 to move to left, and collet 5 transformation becomes Shape, clamps workpiece 14, and now cylinder seat 9 rotates together with main shaft and collet 5.After completion of processing, changing source of the gas, circle is drawn Bar 6 moves to right, and double inclined plane bar 8 moves down under spring force, and cylinder seat 9 and tapered collet 11 move to right under back-moving spring 4 effect, Collet 5 eliminating deformation, unclamps workpiece 14.
Owing to workpiece is played self-centering action by collet, circular pull bar 6 forms relocation mechanism with circular seat 12.Make folder Main axis center is adjusted and eliminates to errors of centration by concrete and workpiece automatically, and therefore part processing precision is carried further High.Use circular pull bar 6 external gas source structure, cancel fixture inside cylinder and import and export tracheae, make clamp structure greatly simplified, use More convenient, safety.
The utility model discloses a kind of turning attachment, it is to avoid lathe frequent start-stop, reduce equipment loss;Utilize source of the gas certainly Move clamping and unclamp workpiece, easy to operate, improve production efficiency;It is furnished with acoustic-optic alarm, can the feelings of alert device clamping at any time Condition, uses " floating " mode of circular pull bar, makes machining accuracy significantly improve, and add job stability, this clamp structure Compact, general adjustable, it is a kind of efficient, safe Green Machining corollary apparatus, it is adaptable to numerically controlled lathe and engine lathe upper shaft The not parking processing of class part.
