After releasing the fixation, the first driving unit 40 is operated so that the piston 43 is reduced to rotate the shaft 20 counterclockwise, and the rotation angle sensed by the sensing unit 80 is In the case of 45 degrees, the operation of the first driving unit 40 may be stopped, and the second driving unit 50 and the third driving unit 60 may be operated to fix the rotation of the shaft 20 .

Meanwhile, in this embodiment, the case where the preset rotation angle of the shaft 20 is at four positions such as 0 degrees, 45 degrees, 90 degrees, and 135 degrees has been described, but the present invention is not limited thereto, and the The set rotation angle may be composed of three, five, or the like positions.

In addition, when the operator does not select any one of the plurality of button units 123 and inputs the rotation angle of the shaft 20 as an arbitrary rotation angle, the control unit 110 controls the first driving unit ( 40) to extend or contract the piston 43 to rotate the shaft 20 in a clockwise or counterclockwise direction, and the rotation angle sensed by the sensing unit 80 is the inputted arbitrary rotation angle. , the first driving unit 40 may be stopped and the second driving unit 50 may be operated to fix the rotation of the shaft 20 .

That is, when the rotation angle of the shaft 20 input from the input unit 120 is an arbitrary rotation angle other than a preset rotation angle, the control unit 110 does not operate the third driving unit 60, The rotation of the shaft 20 may be fixed by operating only the second driving unit 50 .

As described above, the present invention can automatically rotate the workpiece at an arbitrary angle when boring the workpiece, and automatically and firmly fix the workpiece rotated at the arbitrary angle in its state. It relates to a device for controlling a jig for fixing a workpiece that can be processed, and its embodiment will be said to be changeable in various forms. Therefore, the present invention is not limited by the embodiments disclosed herein, and all forms that can be changed by a person of ordinary skill in the art to which the present invention pertains will also fall within the scope of the present invention.
