In addition, in the above state, the return operation of the rack portion 600 is performed while the pressure fluid is supplied to the other side of the hydraulic cylinder 610 operating the rack portion 600. Of course, at the time of the return movement of the rack portion 600, the first clutch gear 510 engaged with the first clutch gear 510 is rotated, but the first clutch gear 520 is separated from the first clutch gear 510 Only the first clutch gear 510 is rotated and the first curvature clutch 520 and the operating shaft 300 are not rotated.

Thus, by repeating the above-described process, all machining on each surface of the workpiece 10 can be performed continuously and quickly.

As a result, the hydraulic tilting index table of the present invention is constructed so that the operation for panning or tilting of the workpiece 10 is performed by the hydraulic pressure, so that it is possible to obtain a rapid movement and to maintain a stable fixed state in a state where the tilting is completed So that not only heavy cutting but also precision machining is possible.

In particular, since the hydraulic tilting index table of the present invention can provide the pressure fluid to each operating portion through the plurality of hydraulic lines 321, 322, 331, 332 formed in the operating shaft 300, It is possible to achieve a simple structure.

The hydraulic tilting index table of the present invention also provides an interlocking structure of the rack portion 600 with the first clutch gear 510 and the first curb clutch 520 so that the tilting (or rotation) of the operating shaft 300 It can be performed at an accurate angle within a short period of time.

The hydraulic tilting index table of the present invention further provides an interlocking structure of the second clutch gear 810 and the second curb clutch 820 so that the operation shaft 300 during processing of the workpiece 10 is rotated in the rotating direction It is possible to prevent flow and further improve the machining accuracy.
