The rotary table having the dividing plate function of the present invention has the function of the dividing plate to indicate the position of the hole to be drilled in the welding operation and the workpiece, and a predetermined number of bolt holes in the workpiece 50 such as a flange or a gasket. When displaying the seat, first, the workpiece 50 is placed on the rotating plate 15 and the workpiece 50 is gripped and fixed by the chuck member 20.

That is, after placing the workpiece 50 on the rotating plate 15, the handle (not shown) by engaging the handle (not shown) to the handle engaging portion 23b of the straight screw 23 of the chuck member 20, the handle (not shown) Turn clockwise to advance the first and second jaws 24 and 25.

When the first jaw 24 and the second jaw 25 are advanced, the first jaw 24 and the second jaw 25 are brought into close contact with the corresponding ends of the work 50 to hold the work 50. 6 and 7, the workpiece 50 is fixed on the rotating plate 15 by the first jaw 24 and the second jaw 25.

When the workpiece 50 is fixed by the chuck member 20 on the rotating plate 15 as described above, the first bolt is loosened and the nut 39 is fastened to the PCD alignment stand 35. While rotating the coupling flange 33 and the second coupling flange 34 to the left and right to fit the PCD of the hole to be displayed on the workpiece 50, and tightening the fixing bolt 38 and the nut 39 is fixed.

At this time, the locking ball 43 of the ball planar 40 fixed to the lower support rod 32 in the circular groove (15a) formed on the outer circumferential surface of the rotating plate 15 is caught.

In this state, when the power switch 16 of one side of the outer case 11 is turned on and the reduction motor 12 is driven, the rotating shaft 14 connected to the gearbox rotates as the gears in the gearbox 13 rotate. The rotating plate 15 is rotated accordingly.

When the rotation of the rotating plate 15 is started, the locking ball 43 of the ball planar 40, which is caught in any one of the circular grooves 15a of the outer circumferential surface of the first rotating plate 15, leaves the circular groove 15a and the rotating plate 15 Is pressed against the outer circumferential surface of the inner side of the screw 41.

As the rotating plate 15 is further rotated, the other circular groove 15a is moved toward the ballplanza 40 and the circular groove 15a is pressed when the circular groove 15a corresponds to the ballplanza 40. The catching ball 43 in close contact with each other is caught again with a click sound in the corresponding circular groove 15a.

At this time, the operator stops the rotation of the rotating plate 15 by the rotational speed adjusting volume 18, and when the rotating plate 15 is stopped, the operator has the display pin fastened to the display pin holder 34c on one side of the PCD alignment table 35. The head 36a of 36 is hit with a tool such as a hammer.

When the worker hits the display pin 36, the spring 42 supporting the display pin 36 from the upper portion of the display pin holder 34c is pressed, and the display pin 36 is lowered, and the sharpness of the display pin 36 is sharp. The bottom is stamped on the corresponding point of the workpiece to indicate the location of the hole.

As the spring 42, which was contracted immediately after the display pin 36 is momentarily lowered, is restored, the display pin 36 is returned to the initial position.

When the display of the hole is finished as described above, the operator rotates the rotating plate 15 again with the rotational speed adjusting volume 18, and when the rotating plate 15 is rotated again, the above-described operation is repeated and the indication of the hole position to be drilled in the workpiece 50 is repeated. Will be

When the marking of the hole on the workpiece 50 is completed, the handle coupled to one side handle engaging portion 23b of the straight screw 23 is rotated counterclockwise to rotate the straight screw 23 counterclockwise.

Accordingly, the first jaw 24 and the second jaw 25 are reversed and separated from the corresponding end of the work 50, and thus the processed work 50 is separated from the rotating plate 15, and the processed work 50 The other workpiece 50 to be lifted and processed is fixed on the rotating plate 15 to mark the hole seat by the above-described process.

Since the rotary table having the divider function of the present invention is provided with the chuck member 20 on the center line of the rotary plate 15, it is necessary to use a separate lathe chuck that grips the workpiece 50 and couples the rotary plate 15. It is possible to grip the workpiece 50 directly on the rotating plate 15 without.

Accordingly, since the mounting of the conventional lathe chuck which is bulky and heavy on the rotary table 10 is omitted, the weight of the rotary table 10 is lighter, easier to handle, and manufacturing cost can be reduced.

The upper jaws 24b and 25b of the first jaw 24 and the second jaw 25 of the chuck member 20 are formed in an arc shape to grip the end portions of the corresponding outer peripheral surfaces of the disc-shaped workpiece 50. It is very easy to fix the work piece 50.

Particularly, the present invention rotary table 10 has a plurality of circular grooves 15a formed on the outer circumferential surface of the rotating plate 15, and hole dividing display means is provided on one side of the ball plate 40 when the rotating plate 15 is rotated. Since the catching ball 43 is caught with a click sound in the circular groove 15a, the display position of the hole to be drilled in the work 50 is accurately recognized, and at this time, the display pin 36 is hit to make a hole in the work 50. The seats can be displayed accurately.

Therefore, the present invention can easily fix the workpiece 50 directly on the rotating plate 15 and accurately display the hole position of the workpiece 50 divided by the hole division display means. It becomes possible.

The rotary table having the divider function of the present invention as described above is provided with the chuck member 20 so as to directly fix the workpiece 50 on the rotary plate 15 easily, so that a separate lathe chuck is omitted. The volume and weight of the 10) can be reduced and manufacturing cost can be reduced, and the circular groove 15a is formed on the outer circumferential surface of the rotating plate 15 to match the hole position of the workpiece 50, and the circular groove (one side of the rotating table 10) 15a), the ball table 40 and the PCD alignment stand 35 for displaying the position of the hole by adjusting the PCD of the hole position and the hole split display means provided with the display pin 36 are installed. In addition to the welding operation in 10) there is an effect such that the position of the hole to be drilled in the workpiece 50 can be easily displayed.
