The specific embodiment
Below, at lathe chuck of the present invention,, describe with reference to accompanying drawing enumerating preferred implementation with having used on the relation of this lathe with the Work piece processing method of chuck.
Fig. 1 is the stereogram of the lathe of an embodiment of the invention with chuck 10, and Fig. 2 is the front view that lathe shown in Figure 1 is used chuck 10.The lathe of present embodiment is arranged on the machining spindle of not shown lathe (for example universal lathe) with chuck 10, workpiece is positioned fixing, being used for by described machining spindle is that high speed rotation is carried out in the axle center with pivot O, thereby with machining tool (for example cutting element) processing work of being scheduled to.
As depicted in figs. 1 and 2, lathe has with chuck 10: the chuck main body 12 of flat cylindrical, and it is arranged on the machining spindle of not shown known lathe; 3 claws 14, they dispose with equal angles (for example every 120 °) along the circumferencial direction of the front surface 12a of chuck main body 12, advance and retreat simultaneously diametrically and clamping work pieces W (with reference to the chain-dotted line among Fig. 2); And 3 adjusting pin 16a, 16b, 16c, they are separately positioned between the adjacent claw 14.
3 claws 14 are 3 following claws: can by manual operation can dismounting on the side of chuck main body 12 driving handle 18 and along the radially advance and retreat simultaneously of chuck main body 12.Promptly, each claw 14 can be each guide rail 20 that extends radially from pivot O in the front surface 12a upper edge of chuck main body 12 and advance and retreat with respect to pivot O, can control the outer peripheral face of workpiece W simultaneously by enough each chuck face 14a, thereby position fixing (with reference to Fig. 2) towards pivot O.
Herein, with reference to Fig. 3 and Fig. 4, an example of the advance and retreat structure of the claw 14 that utilize to drive handle 18 is described.Fig. 3 is the cut-away section stereogram behind the front surface 12a of excision chuck main body 12, and Fig. 4 is the sectional view of chuck main body 12 shown in Figure 3.In addition, the advance and retreat structure that this utilization drives the claw of handle is known mechanism, has therefore simplified its diagram in Fig. 3 and Fig. 4.Certainly, can also adopt following illustrated advance and retreat structure advance and retreat structure in addition.
As shown in Figure 3 and Figure 4, the inboard of front surface 12a in the inside of chuck main body 12, be provided with vortex-like key member 22, the driven wheel of differential 22c that this vortex-like key member 22 has the 22a of plectane portion, erects the vortex-like jut 22b on the front surface that is arranged on the 22a of plectane portion and give prominence to from center, the back side.On the other hand, each claw 14 engages with this vortex-like jut 22b sliding freely by keyway 14b, and keyway 14b is formed on the back side of each claw 14, is made of the curve shape corresponding with the volute shape of vortex-like jut 22b.
The driven wheel of differential 22c and the driving bevel gear 24a of the front end that is arranged on driving shaft 24 (lower end) that rotates by driving handle 18 mesh.Thus, when rotary manipulation driving handle 18 rotated driving bevel gear 24a, driven wheel of differential 22c also rotated, and 22a of plectane portion and vortex-like jut 22b are that the axle center is rotated with pivot O thus.
Therefore, vortex-like jut 22b vortex-like (spiral-shaped) is set to shape (so-called Archimedian screw) equally spaced approaching with respect to initial point based on its anglec of rotation and that leave.Thus, when when driving the vortex-like jut 22b of handle 18 rotations, under the snap action of this vortex-like jut 22b and keyway 14b, each claw 14 is along guide rail 20 (with reference to Fig. 2) advance and retreat equidistantly diametrically simultaneously.
Return Fig. 1 and Fig. 2, adjusting pin 16a～16c is the screw with the head that can operate with staff, screws togather with each hold-down nut 26 on the front surface 12a that is fixed on chuck main body 12.Thus, the head of operator's rotary manipulation adjusting pin 16a～16c, thus, each adjusting pin 16a～16c rotates separately, in fact infinitely advance and retreat.
As can be seen from Figure 2, adjusting pin 16a～16c is configured between each claw 14 with equal angles (for example every 120 °), and each claw 14 disposes with equal angles (for example every 120 °) along the circumferencial direction of the front surface 12a of chuck main body 12.That is, each adjusting pin 16a～16c is separately positioned on about on the symmetrical and relative position of the pivot O of chuck main body 12, and each claw 14 and each adjusting pin 16a～16c are arranged alternately with equal angles (for example every 60 °) on described circumferencial direction.
Then, describe with the Work piece processing method of chuck 10 having used the lathe that as above constitutes with reference to the flow chart of Fig. 5.
For example, when dwindling the machining of circular bar-shaped workpiece W diameter, at first, all claws 14 and adjusting pin 16a～16c appropriateness on the direction of leaving from pivot O is retreated according to the external diameter of workpiece W.
Therefore, in the step S1 of Fig. 5, be that benchmark is configured in workpiece W near the center of each claw 14, and rotary manipulation drive handle 18 with pivot O, position fixing thereby control workpiece W with the chuck face 14a of 3 claws 14.
In step S2, with each claw 14 positioning and fixing under the state behind the workpiece W, all adjusting pin 16a～16c are advanced towards pivot O, thereby make its front end and workpiece W butt.
In step S3, rotary manipulation drives handle 18 under the butt state of keeping adjusting pin 16a～16c and workpiece W, leaves thereby each claw 14 is retreated from workpiece W.At this moment, control workpiece W by each adjusting pin 16a～16c according to above-mentioned steps S2, though therefore make claw 14 away from, workpiece W can not come off yet.
In step S4, drive control on one side the machining spindle (not shown) of this lathe with the lathe of chuck 10 is installed, with the workpiece W of predetermined low-speed rotation/feeding by adjusting pin 16a～16c positioning and fixing, make the outer peripheral face butt of not shown micrometer (sampling inspection) and workpiece W on one side, carry out the deviation check (with respect to the off-centre inspection of pivot O) of this workpiece W, and adjust the advance and retreat position of each adjusting pin 16a～16c separately, carry out the eccentric position adjustment (centering) of workpiece W.
In step S5, rotary manipulation drives handle 18, make each claw 14 once more with according to above-mentioned steps S4, by adjusting pin 16a～16c positioning and fixing and adjusted the workpiece W butt behind the eccentric position.Thus, workpiece W is correctly carrying out under the state that deviation adjusts, by claw 14 and adjusting pin 16a～16c positioning and fixing reliably.
Thus, in step S6, unload driving handle 18 from chuck main body 12, and drive the machining spindle of the described lathe of control, drive lathe with chuck 10 with predetermined process velocity rotation, make predetermined machining tool and workpiece W butt, this workpiece W can be processed into the shape of expectation thus.
As mentioned above, lathe chuck 10 and Work piece processing method according to present embodiment, have diametrically 3 claws 14 of advance and retreat simultaneously and be configured between each claw 14 diametrically the adjusting pin 16a～16c of advance and retreat separately, thus can be easily and correctly carry out in the past only with the claw of advance and retreat simultaneously the time, being difficult to the workpiece W deviation fine setting (adjustment of eccentric position) diametrically carried out.Thus, for example, even under the situation that the eccentric position of workpiece W under the state that has carried out positioning and fixing with claw 14 departs from, perhaps workpiece W is inferior from situation eccentric a little on its precision, also can control and positioning and fixing workpiece W easily and promptly, can correctly adjust its eccentric position.
At this moment, adjusting pin 16a～16c by with the front surface 12a that is fixed on chuck main body 12 on the screw that screws togather of hold-down nut 26 constitute, simplified its structure thus, and fully guaranteed operability.Certainly, if adjusting pin 16a～16c can distinguish separately advance and retreat and can with workpiece W butt, then also can be other structures.
In addition, lathe is the simple structure of only having appended adjusting pin 16a～16c in the structure that is provided with general claw 14 with chuck 10, therefore under the situation of the correct centering of carrying out workpiece W, can use claw 14 and adjusting pin 16a～16c, carry out correct deviation adjustment according to the workpiece W of order shown in Figure 5, on the other hand, under the situation of the correct centering that does not need workpiece W, also can be made as the general using method of under the state that adjusting pin 16a～16c is retreated, only using claw 14, thereby versatility is higher.
In addition, the lathe of variation that can be as shown in Figure 6 is such with chuck 50, suitably changes the number of claw and adjusting pin.Illustration lathe have 4 claws 14 with chuck 50 and be separately positioned on the structure of 4 adjusting pin 16a～16d therebetween.Each claw 14 along the circumferencial direction of chuck main body 12 with uniformly-spaced (for example every 90 °) configuration, each adjusting pin 16a～16d also along described circumferencial direction with uniformly-spaced (for example every 90 °) configuration, each claw 14 and each adjusting pin 16a～16d are arranged alternately with equal angles (for example every 45 °) on described circumferencial direction.
Therefore, be provided with under the situation of odd number claw 14 like that with chuck 10 at as shown in Figure 2 lathe, preferred each adjusting pin 16a～16c is arranged on about on this lathe position relative with each claw 14 with the pivot O symmetry of chuck 10, on the other hand, be provided with like that with chuck 50 under the situation of even number claw 14 at as shown in Figure 6 lathe, preferred adjusting pin 16a～16d be arranged on 2 adjusting pins each other (for example adjusting pin 16a, 16c) about on this lathe position relative with the pivot O symmetry of chuck 50.Like this, with respect to by being held in the workpiece at center, can make the direction of the power that each claw and each adjusting pin produce on the circumferencial direction of lathe, become uniform angle, can improve the operation of the deviation adjustment of the position stability of workpiece and adjusting pin with chuck.
The invention is not restricted to above-mentioned embodiment, in the scope that does not break away from purport of the present invention, can adopt various structures or operation certainly.
For example, adjusting pin there is no need to be configured between all adjacent claws, as long as be arranged between the claw more than at least 2.
