Abstract
The utility model relates to a centre floating chuck comprising a chuck body and a three-jaw. The three-jaw in the chuck body can rotate around a positioning pin; a center is slidingly arranged in the front part of the chuck body; a draw rod is arranged in the chuck body; upper and lower floating bodies are sheathed on the draw rod; a spring is arranged in the chuck body to cause the three-jaw and the lower floating body to keep conical surface contact. The utility model can reduce positioning errors, improve machining precision, increase production efficiency, replace numerous nonstandard chucks to become standard series universal chucks, guaranteed the precision and carry out the turning, milling, grinding, gear shaping and gear hobbing processing to parts of axis class.
Description
The utility model belongs to a kind of lathe clamping device, particularly a kind of top formula floating chuck.
Along with the development of metal machining Processes and apparatus, add the also renewal thereupon of required anchor clamps in man-hour.Scroll chuck is widely used as main machining universal fixturing, but scroll chuck particularly to the processing of axial workpiece, can only be applicable to the processing of low precision because this body structure is limit.This is that its clamping precision is 0.1mm because workpiece is contained between scroll chuck and thimble, so, when workpiece fine finishining, have to adopt two traditional thimbles to add the mode of dial and chuck, its clamping precision is 0.03mm.To some special axial workpieces, have to the adopting process hole or supplementary means such as technology ring, just can carry out machining, bring inconvenience to processing like this, and influence the raising of production efficiency.
The purpose of this utility model is at the deficiency with upper chuck, designs a kind of top formula floating chuck, and it can reduce position error, improves machining accuracy, can replace numerous nonstandard anchor clamps and becomes the standard series universal chuck, guarantees the product precision.
The purpose of this utility model is finished as follows: the three-jaw in the chuck body can rotate around alignment pin, top being slidingly mounted in the chuck body front end arranged, pull bar is arranged in the chuck body, be set with upper and lower two buoyancy body on the pull bar, have spring to make three-jaw and following buoyancy body keep the conical surface often to contact in the chuck body.During work, two top location, three-jaw plays unsteady clamping action, no matter thereby thick, fine finishining, design basis and technological datum are overlapped, reduce position error; At the car of axial workpiece, mill, grind, insert, in the gear hobbing processing, can replace numerous various nonstandard anchor clamps, and become the standard series universal chuck.
Top afterbody can have spring to connect with chuck body, and the chuck body front end also is equipped with spacer pin.When top location, because of axial limiting is arranged, so the production efficiency height easily guarantees the converted products precision.
The working end of three-jaw is movably installed with the adjustment piece, along with the difference of processing work diameter, can adjust the position of piece on three-jaw easily.Adjusting the piece end has interchangeable, can change at any time during wearing and tearing.
Between the upper and lower buoyancy body spring is installed, to control two gaps of floating between the spheroid.
Below in conjunction with accompanying drawing the utility model is described in further detail.
Fig. 1 is a kind of concrete structure cutaway view of the utility model.
Fig. 2 is the vertical view of Fig. 1.
With reference to figure, the interior interference fit of chuck body (13) is equipped with lining (14), top (9) are slidingly mounted in the lining (14), spring (12) in top (9) afterbody connects with chuck body (13) by baffle plate (16) and screw (15), and spacer pin (11) is assemblied on the lining (14) by fixed head (10) and screw (8).If processing work does not need axial location, dismountable spring (12) and spacer pin (11).During work, after workpiece is contained on top (9), promotion by tail stock for machine tool top (or the thimble in another subsidiary body), top (9) and workpiece are moved to the chuck direction together, compress spring (12) simultaneously, run into spacer pin (11) up to workpiece end face, like this, the position fixing process of workpiece all finishes.Be moved to the left by pull bar (20) then, buoyancy body (18) and (17) also are moved to the left, and by moving of buoyancy body (18) conical surface, impel three-jaw (3) to rotate around alignment pin (4), thereby clamping work pieces have so just been finished the location and the clamping of workpiece.Following buoyancy body (18) is to make itself and three-jaw (3) keep often contacting by spring (2), it is not subjected to the interference of remaining parts in the chuck body, when wherein a claw touches the height point of workpiece, buoyancy body (18) is moved down, thereby making in addition, two claws touch surface of the work successively, along with following buoyancy body (18) constantly is moved to the left, and reach the clamping of floating, and do not interfere top location.Because pull bar (20) direction of pull is fixed, and buoyancy body (18) leans on last buoyancy body (17) to guarantee good quick condition because of the off-centre of floating down.Spring (19) guarantees good displacement between two buoyancy body.Spring (2) is installed in the chuck body (13) by plug (1).The adjustment piece (5) of three-jaw (3) working end is fixing by screw (6), and the working face of adjusting piece (5) has interchangeable (7), and pull bar (20) can be pneumatic or be surged.
Owing to add man-hour, adopt two top location, three-jaw only rises to float and clamps, so can reach arm's length standard≤0.03mm, the processing work diameter is unrestricted, only needs to change the position, hole of adjusting piece (5) and interchangeable (7) and gets final product.This chuck can carry out axial workpiece Vehicle Processing, mill processing, grinding and gear shaping and gear hobbing.
Claims (5)
1, a kind of top formula floating chuck, comprise chuck body (13) and three-jaw (3), it is characterized in that the three-jaw (3) in the chuck body (13) can rotate around alignment pin (4), there is top dirt (9) to be slidingly mounted in chuck body (13) front end, pull bar (20) is arranged in the chuck body (13), be set with buoyancy body (17) and following buoyancy body (18) on the pull bar (20), have spring (2) to make three-jaw (3) and following buoyancy body (18) keep the conical surface often to contact in the chuck body.
2, chuck according to claim 1 is characterized in that top (9) afterbody has spring (12) to connect with chuck body (13), and chuck body (13) front end also is equipped with spacer pin (11).
3, chuck according to claim 1 is characterized in that the working end of three-jaw (3) is movably installed with adjustment piece (5).
4, chuck according to claim 3, it is characterized in that adjusting piece (5) end has interchangeable (7).
5, chuck according to claim 1 is characterized in that between buoyancy body (17) and the following buoyancy body (18) spring (19) being installed.
