The specific embodiment
Below, for chuck for lathe of the present invention, on the relation of the Work piece processing method with having used this chuck for lathe, enumerate preferred embodiment, with reference to accompanying drawing, describe.
Fig. 1 is the stereogram of the chuck for lathe 10 of an embodiment of the invention, and Fig. 2 is the front view of the chuck for lathe 10 shown in Fig. 1.The chuck for lathe 10 of present embodiment for example is arranged on, on the machining spindle of not shown lathe (universal lathe), workpiece is positioned fixing, carry out High Rotation Speed as axle center for by described machining spindle, take pivot O, thereby for example, with predetermined machining tool (cutting element) processing work.
As depicted in figs. 1 and 2, chuck for lathe 10 has: 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 along the circumferencial direction of the front surface 12a of chuck main body 12 with equal angles (for example, every 120 °) configuration, diametrically simultaneously advance and retreat and clamping work pieces W(with reference to the chain-dotted line in Fig. 2); And 3 adjusting pin 16a, 16b, 16c, they are separately positioned between adjacent claw 14.
3 claws 14 are 3 following claws: driving handle 18 that can dismounting on the side of chuck main body 12 by manual operation and along the radially advance and retreat simultaneously of chuck main body 12.; each claw 14 can be advanced and retreat with respect to pivot O along be each guide rail 20 extended radially from pivot O on the front surface 12a of chuck main body 12; can control the outer peripheral face of workpiece W by enough 14a of each chuck face towards pivot O simultaneously, thereby position fixing (with reference to Fig. 2).
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 be the excision chuck main body 12 front surface 12a after the cut-away section stereogram, Fig. 4 is the sectional view of the chuck main body 12 shown in Fig. 3.In addition, it is known mechanism that this utilization drives the advance and retreat structure of the claw of handle, therefore in Fig. 3 and Fig. 4, has simplified its diagram.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, this vortex-like key member 22 has the 22a of plectane section, erect vortex-like jut 22b on the front surface that is arranged on the 22a of plectane section and the outstanding driven wheel of differential 22c from center, the back side.On the other hand, each claw 14, by keyway 14b, engages with this vortex-like jut 22b sliding freely, and keyway 14b is formed on the back side of each claw 14, curve shape corresponding to volute shape with vortex-like jut 22b, consists of.
Driven wheel of differential 22c and the driving bevel gear 24a of the front end that is arranged on driving shaft 24 (lower end) rotated by driving handle 18 mesh.Thus, when rotary manipulation drives handle 18 to rotarily actuate bevel gear 24a, driven wheel of differential 22c also rotates, and the 22a of plectane section and vortex-like jut 22b be take pivot O and be rotated as axle center thus.
Therefore, vortex-like jut 22b vortex-like (spiral-shaped) is set to the shape (so-called Archimedian screw) that equally spaced approaches and leave with respect to initial point based on its anglec of rotation.Thus, when when driving the vortex-like jut 22b of handle 18 rotation, under the snap action of this vortex-like jut 22b and keyway 14b, each claw 14 along guide rail 20(with reference to Fig. 2) advance and retreat equidistantly diametrically simultaneously.
Return to Fig. 1 and Fig. 2, adjusting pin 16a～16c is the screw with the head that can be operated with staff, with each hold-down nut 26 on the front surface 12a that is fixed on chuck main body 12, screws togather.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 configures 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 the position symmetrical and relative about 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, with reference to the flow chart of Fig. 5 to having used the Work piece processing method of chuck for lathe 10 as constructed as above to describe.
For example, when being dwindled the machining of circular bar-shaped workpiece W diameter, at first, according to the external diameter of workpiece W, all claws 14 and adjusting pin 16a～16c appropriateness on the direction of leaving from pivot O is retreated.
Therefore, in the step S1 of Fig. 5, take pivot O near benchmark is configured in workpiece W at each claw 14 center, and rotary manipulation drives handle 18, position fixing thereby control workpiece W with the chuck face 14a of 3 claws 14.
In step S2, under the state after with each claw 14 location, having fixed workpiece W, all adjusting pin 16a～16c are advanced towards pivot O, thereby make its front end and workpiece W butt.
In step S3, under the butt state that maintains adjusting pin 16a～16c and workpiece W, rotary manipulation drives handle 18, thereby each claw 14 is retreated from workpiece W, leaves.Now, according to above-mentioned steps S2, by each adjusting pin 16a～16c, control workpiece W, though therefore make claw 14 away from, workpiece W can not come off yet.
In step S4, drive the machining spindle (not shown) of controlling the lathe that this chuck for lathe 10 is installed on one side, locate fixing workpiece W with low speed rotation/feeding of being scheduled to by adjusting pin 16a～16c, 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 bias inspection of pivot O) of this workpiece W, and adjust separately the advance and retreat position of each adjusting pin 16a～16c, carry out the eccentric position adjustment (centering) of workpiece W.
In step S5, rotary manipulation drives handle 18, make each claw 14 again with according to above-mentioned steps S4, fixing and adjusted the workpiece W butt after the eccentric position by adjusting pin 16a～16c location.Thus, workpiece W is correctly carrying out under the state of deviation adjusting, by claw 14 and adjusting pin 16a～16c, is located reliably fixing.
Thus, in step S6, from chuck main body 12, unload and drive handle 18, and drive the machining spindle of controlling described lathe, rotarily actuate chuck for lathe 10 with the process velocity of being scheduled to, make predetermined machining tool and workpiece W butt, this workpiece W can be processed into to the shape of expectation thus.
As mentioned above, chuck for lathe 10 and Work piece processing method according to present embodiment, there are 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 being difficult to the workpiece W deviation fine setting (adjustment of eccentric position) diametrically of carrying out only with the claw of advance and retreat simultaneously the time.Thus, for example, even in the situation that the eccentric position that has carried out locating workpiece W under fixing state with claw 14 departs from, perhaps workpiece W is inferior from situation eccentric a little on its precision, also can be easily and promptly workpiece W controlled and locate fixingly, can correctly adjust its eccentric position.
Now, the screw that adjusting pin 16a～16c is screwed togather by the hold-down nut 26 on the front surface 12a with being fixed on chuck main body 12 forms, and has simplified thus its structure, and has fully guaranteed operability.Certainly, if adjusting pin 16a～16c can distinguish separately advance and retreat and can with workpiece W butt, can be also other structures.
In addition, chuck for lathe 10 is the simple structure of only having appended adjusting pin 16a～16c in the structure that is provided with general claw 14, therefore in the situation that carry out the correct centering of workpiece W, can use claw 14 and adjusting pin 16a～16c, carry out the correct deviation adjusting according to the workpiece W of the order shown in Fig. 5, on the other hand, in the situation that do not need the correct centering of workpiece W, also can be made as the general using method of only using claw 14 under the state that adjusting pin 16a～16c is retreated, thereby versatility is higher.
In addition, the chuck for lathe 50 of variation that can be as shown in Figure 6 is such, suitably changes the number of claw and adjusting pin.There are 4 claws 14 and be separately positioned on the structure of 4 adjusting pin 16a～16d therebetween exemplified with chuck for lathe 50.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, in the situation that chuck for lathe 10 as shown in Figure 2 is provided with odd number claw 14 like that, preferably each adjusting pin 16a～16c is arranged on the position symmetrical and relative with each claw 14 about the pivot O of this chuck for lathe 10, on the other hand, in the situation that chuck for lathe 50 as shown in Figure 6 is provided with even number claw 14 like that, preferably adjusting pin 16a～16d be arranged on 2 adjusting pins each other (for example adjusting pin 16a, 16c) about the pivot O of this chuck for lathe 50 on symmetrical and relative position.Like this, with respect to by being held in the workpiece at center, the direction of the power that can make each claw and each adjusting pin produce becomes uniform angle on the circumferencial direction of chuck for lathe, can improve the workability of the deviation adjusting of the position stability of workpiece and adjusting pin.
The invention is not restricted to above-mentioned embodiment, in the scope that does not break away from purport of the present invention, certainly can adopt various structures or operation.
For example, adjusting pin there is no need to be configured between adjacent all claws, as long as be arranged between the claw more than at least 2.
