Abstract
The open a kind of turning attachment of the present invention, it uses connecting plate, cylinder sleeve, fixed plate to connect with the first fixed screw successively, fixes seat and be connected with fixed plate with the second fixed screw；Piston is arranged in cylinder sleeve, three lower limbs of having helped pull a cart, and its leg is through the hole in fixed plate, then is connected with the 3rd fixed screw with piston；Floating bushing is arranged in helping pull a cart, cover plate be provided with more than three protruding, help pull a cart be provided with three with upper notch, when after protruding alignment recess, push and load onto cover plate and turn over an angle, just can pin workpiece；Being provided with more than three on helping pull a cart and fasten screw, it is cased with spring, the other end of spring contacts with the removable pin on floating bushing, and its effect is automatically floating bushing to be ejected together with workpiece after work pieces process completes；The rear portion of piston is connected with pull bar connecting screw, main shaft pull bar successively.The present invention by the axial force along workpiece Work-sheet pressing, it is to avoid because of the circularity over tolerance caused along workpiece radial pressure.
Description
Technical field
The present invention relates to a kind of turning attachment.
Background technology
Lathe is to utilize the rotation of workpiece and the rectilinear movement of cutter to process workpiece.Engine lathe is used
Workpiece clamped by chuck, and chuck rotates with lathe spindle, and workpiece follows chuck to rotate together.
It is that three (or four) claws are the most afterburning along workpiece that chuck for lathe can clamp the principle of workpiece,
This power is sufficiently large, enough big of the frictional force that produces therefrom, and workpiece is clamped tightly.This way
Processing less demanding to general Roundness of Workpiece is very suitable for.But high processing work is required for circularity
Part, because claw is sufficiently large along the power of workpiece radial direction, when workpiece is sandwiched on chuck, the processed place of workpiece
Circularity is by the accuracy guarantee of lathe itself, but after workpiece takes off from chuck, disappears along workpiece power radially,
The circularity at the processed place of workpiece changes, and often can cause circularity over tolerance.
In view of this, the special proposition present invention.
Summary of the invention
The technical problem to be solved in the present invention is to overcome the deficiencies in the prior art, it is provided that a kind of lathe folder
Tool.
For solving above-mentioned technical problem, the present invention uses the basic conception of technical scheme to be: a kind of lathe
Fixture, clamps workpiece tightly by the axial compressive force along workpiece, thus avoids because of along workpiece radial pressure
The circularity over tolerance caused.
The concrete structure of the present invention is: be connected with lathe headstock with connecting plate, with connecting plate, cylinder sleeve,
Fixed plate connects with the first fixed screw successively, and fixing seat is connected with fixed plate with the second fixed screw；Piston
Being arranged in cylinder sleeve, three lower limbs of having helped pull a cart, its leg is through the hole in fixed plate more solid with the 3rd with piston
Determine screw to connect；Floating bushing is arranged in helping pull a cart, and the overall dimensions of floating bushing is slightly less than the inner chamber size helped pull a cart,
The inner chamber of floating bushing is slightly larger in dimension than the overall dimensions of workpiece；Cover plate be provided with more than three protruding, help pull a cart on
Be provided with three with upper notch, when after protruding alignment recess, push and load onto cover plate and turn over an angle, just may be used
Pin workpiece；The front end of fixing seat be provided with three with the compression point protruded above, the front end of cover plate be provided with three with
The compression point protruded above；On helping pull a cart, it is provided with more than three fastens screw, it is cased with spring, spring another
One end contacts with the removable pin on floating bushing, its effect be after work pieces process completes automatically floating bushing together with
Workpiece ejects together；The rear portion of piston is connected with pull bar connecting screw, main shaft pull bar successively.
Present invention have the advantage that it can be clamped workpiece tightly by the axial compressive force along workpiece, thus
Avoid the circularity over tolerance because causing along workpiece radial pressure.
Accompanying drawing explanation
Accompanying drawing 1 is the top view of the present invention, and the pull bar connecting screw at piston rear portion, main shaft pull bar do not have
Draw in the drawings.
Accompanying drawing 2 is the profile of the present invention, and the pull bar connecting screw at piston rear portion, main shaft pull bar do not have
Draw in the drawings.
Detailed description of the invention
As shown in drawings, one turning attachment of the present invention, it is connected with lathe headstock with connecting plate 1,
With the first fixed screw 4, (the first fixed screw 4 has three or three successively for connecting plate 1, cylinder sleeve 2, fixed plate 3
More than individual) connect, fix seat 5 second fixed screw 6 (the second fixed screw 6 has three or more than three)
It is connected with fixed plate 3；Piston 7 is arranged in cylinder sleeve 2, and helping pull a cart 8 has three lower limbs, and its leg is through fixing
Hole on plate 3, then be connected with the 3rd fixed screw 9 with piston 7；Floating bushing 13 is arranged on helps pull a cart in 8,
The overall dimensions of floating bushing 13 be slightly less than help pull a cart 8 inner chamber size, the inner chamber of floating bushing 13 is slightly larger in dimension than
The overall dimensions of workpiece；There are three (or more than three) protruding on cover plate 10, help pull a cart and have three (or three on 8
More than individual) recess, when after protruding alignment recess, push and load onto cover plate 10 and turn over an angle, just can lock
Live workpiece；The compression point 12 that the front end of fixing seat 5 has three (or more than three) to protrude, the front end of cover plate 10
There is the compression point 11 that three (or more than three) protrude；Three (or more than three) are had on 8 to fasten spiral shell helping pull a cart
Silk 14, it is cased with spring 15, and the other end of spring 15 contacts with the upper removable pin 16 of floating bushing 13；
The rear portion of piston 7 is connected with pull bar connecting screw, main shaft pull bar successively, and main shaft pull bar is by hydraulic mechanism control
Can translation vertically, thus control to help pull a cart 8, cover plate 10 translation, reach to compress or unclamp the purpose of workpiece.
The above, to those skilled in the art, can be according to the skill of the present invention
Other various corresponding changes and deformation are made in art scheme and technology design, and all these change and deformation are all
The scope of the claims of the present invention should be belonged to.
