Abstract
The invention provides a three-jaw centrifugal force self-centering chuck which comprises a chuck body, clamping jaws, centrifugal shafts, plug screw shafts, centrifugal rolling sleeves and fixed shafts, wherein three uniformly distributed straight grooves are formed in the end surface direction of the chuck body; three uniformly distributed titled grooves are formed in the circumference direction; three uniformly distributed fixed shaft holes and one central hole are further formed inside the chuck body; the clamping jaws are arranged inside the straight grooves; an inner threaded hole which is parallel and symmetry with the central line of the titled groove surface is formed in each titled groove; the plug screw shafts are screwed inside the inner threaded holes through outer threads; springs are sleeved on the plug screw shafts; clamping grooves are formed in the clamping jaws; the centrifugal shafts penetrate through the clamping grooves and are installed inside the titled grooves of the chuck body; inner holes are formed in two ends of the centrifugal shafts; the centrifugal shafts are sleeved on the plug screw shafts through the inner holes; and the fixed shafts penetrate through the fixed shaft holes and the inner holes of the clamping jaws to be assembled inside the chuck body. The three-jaw centrifugal force self-centering chuck is convenient to use, reduces the working intensity, improves the production efficiency, shortens the equipment manufacturing period, lowers the cost and at the same time improves the machining precision.
Description
Technical field
The present invention relates to lathe field of machining, relate in particular to a kind of lathe centrifugal force automatic centring locking scroll chuck device.
Background technology
Lathe three-claw chuck assembly, by driving claw power used different, is divided into manually and automatic two kinds at present, and manually scroll chuck exists the problems such as inconvenient, labour intensity is large, production efficiency is low of using; Automatically scroll chuck, although alleviated labour intensity, needing increases hydraulic means or pneumatic means, has long, the problem such as cost is high, Operation and Maintenance is complicated of device fabrication cycle.
Summary of the invention
The present invention is directed to the problems referred to above, a kind of three-jaw centrifugal force self-centering chuck is provided, object is: chuck body utilizes centrifugal force clamping work pieces while rotating, when stopping operating, chuck body utilizes Compress Spring elastic returning original state, reduce labour intensity, enhance productivity, shorten the device fabrication cycle, reduce costs expense, improve machining accuracy simultaneously.
Technical solution of the present invention:
Three-jaw centrifugal force self-centering chuck, comprises chuck body and claw, it is characterized in that: described chuck also comprises centrifugal shaft, plug screw axle, centrifugal roll sleeve and fixed axis; Described chuck body end face direction has three equally distributed straight troughs, and circumferencial direction has three equally distributed skewed slots, and chuck body inside also has three equally distributed fixed shaft holes and a centre bore; Described claw is placed in straight trough, and each skewed slot has the internal thread hole parallel and symmetrical with inclined trough surface center line; Described plug screw axle is tightened in by external screw thread in the internal thread hole of chuck body, and on plug screw axle, cover has spring; On described claw, have draw-in groove, centrifugal shaft is contained in chuck body skewed slot through draw-in groove, and centrifugal shaft two ends have endoporus, centrifugal shaft by inner hole sleeve on plug screw axle; Described fixed axis is tight with in chuck body through fixed shaft hole and claw endoporus.
The internal thread hole of described each skewed slot is at least two.
Described internal thread hole diameter is larger than skewed slot width.
Described spring is Compress Spring.
Described centrifugal shaft is connected with draw-in groove by centrifugal roll sleeve.
Beneficial effect of the present invention:
The present invention is easy to use, reduces labour intensity, enhances productivity, and shortens the device fabrication cycle, reduces costs expense, improves machining accuracy simultaneously.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Fig. 2 is A-A sectional structure schematic diagram in Fig. 1.
In figure: 1, chuck body; 2, claw; 3, centrifugal shaft; 4, plug screw axle; 5, Compress Spring; 6, centrifugal roll sleeve; 7, fixed axis; 8, rotation thimble; 9, workpiece; 10, tailstock center.
The specific embodiment
Below in conjunction with drawings and Examples, illustrate the present invention.
As depicted in figs. 1 and 2, a kind of three-jaw self-centering chuck, comprises chuck body 1, claw 2, centrifugal shaft 3, plug screw axle 4, centrifugal roll sleeve 6 and fixed axis 7.Chuck body 1 end face direction has three equally distributed straight troughs, claw 2 is placed in straight trough, circumferencial direction has three equally distributed skewed slots, and each skewed slot has at least two internal thread holes parallel and symmetrical with inclined trough surface center line, and internal thread hole diameter is larger than skewed slot width; Chuck body inside also has three equally distributed fixed shaft holes and a centre bore.Plug screw axle 4 is tightened in by external screw thread in the internal thread hole of chuck body 1, and on plug screw axle 4, cover has Compress Spring 5, and Compress Spring 5 is loaded in internal thread hole.Centrifugal shaft 3 two ends have endoporus, and centrifugal shaft 3, and can move by inner hole sleeve on plug screw axle 4 on plug screw axle 4, prevents from throwing away chuck body 1.On claw 2, have draw-in groove, centrifugal shaft 3 is contained in chuck body 1 skewed slot, and can, in the interior movement of skewed slot 1, by centrifugal roll sleeve 6, in draw-in groove, move.Described fixed axis 7 is tight with in chuck body 1 through fixed shaft hole and claw 2 endoporus.Rotation thimble 8 is loaded in chuck body 1 centre bore by Morse taper shank; Tailstock center 10 and rotation thimble 8 will have compared with high-axiality.
Concrete use procedure:
Workpiece 9 as shown in Figure 1, needs its middle slot portion size of turning, and rotation thimble 10 is loaded in chuck body 1 centre bore:
First according to the length of workpiece 9, adjust tailstock center 10, make tailstock center 10 and rotation thimble 8 distances moderate, the size to fit of pressure, pushes up to obtain too tight easy burn-out workpiece and thimble, pushes up not tightly, and turning accuracy does not reach requirement.
Secondly according to the material of workpiece 9 and external diameter size, adjust lathe spindle rotating speed, bite and feeding speed size etc.
Again start lathe spindle motor, by lower main axis rotation knob, chuck body 1 is rotated, centrifugal shaft 4 and centrifugal roll sleeve 6 outwards move under centrifugal action, drive claw 2 clamping work pieces that turns clockwise, and start turning processing.
After last workpiece 9 processes, press lathe spindle and stop knob, main shaft stops the rotation, and chuck body 1 stops the rotation thereupon, and in claw 2 skewed slots, under Compress Spring 5 effects, claw 2, centrifugal shaft 4 and centrifugal roll sleeve 6 restore to the original state, and workpiece unclamps, and takes out workpiece.Wait for next operation cycle.
As heavier in workpiece, available other lifting device is installed workpiece.
To sum up, the present invention produces a desired effect.
