BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a machine tool, and more particularly, to an apparatus and method for fixing a work piece to a machine tool.

In general, amorphous workpieces made by casting or forging maintain various shapes such as rectangles and squares, without maintaining a regular angle or plane.

In the case of manufacturing various mechanical parts by machining a non-shaped workpiece made of casting, forging, or the like with a machine tool such as a milling machine, a vise is mainly used as a fixing device for fixing the corresponding amorphous workpiece.

When a workpiece is fixed with a vice when the workpiece is machined with a machine tool, a gap between the movement jaw of the vice and the workpiece, or a gap between the fixed jaw of the vice and the workpiece, So as to firmly fix the amorphous workpiece between the moving jaw and the fixed jaw of the vise firmly and tightly.

However, when the wedge is used to fix the workpiece with the vice as described above, there is a problem that it takes a long time to fix the workpiece in a proportional manner to the degree of the irregularity of the workpiece.

For example, as the irregular outer surface of the irregularly shaped workpiece is severely curved, various types of wedges must be prepared and used. As a result, fixing time of the irregularly shaped workpiece is required.

In addition, even if the wedge is inserted into the gap of the vise as described above, if the wedge is displaced from its original position or is pushed in the unspecified direction from its original position, the uncut workpiece is machined (for example, by a milling cutter) There is a problem in that the workpiece is pushed downward or sideways of the vise, resulting in work defects.

2, the operator first places the left leg 113 and the right leg 114 of the electromagnet holder 110 on the upper surface of each of the pair of horizontal pedestals 130, (S110) so that the atypical workpiece 200 is stuck to the rear vertical plate 123 and the first fixing plate 150 in a horizontal state.

3, when the workpiece 200 is positioned between the rear vertical plate 123 and the first fixing plate 150, the worker moves the hydraulic cylinder 140 fixed to the support base 120 And the first fixing plate 150 is moved toward the rear vertical plate 123 and then stopped at a predetermined point so that the electromagnet is rotated by the fixing jig 170 between the rear vertical plate 123 and the first fixing plate 150 111) to secure a space for pushing and fixing the fixed and unprocessed workpiece 200 (S120).

At this time, when the worker presses the forward button of the operation panel, the piston rod 141 of the hydraulic cylinder 140 advances and pushes the first fixing plate 150 toward the rear vertical plate 123, When the worker releases his / her forward button and stops the forward button pressing operation, the forward operation of the piston rod 141 is stopped and the first fixing plate 150 stops at the corresponding point.

The worker first changes the work order to attach the amorphous workpiece 200 to the electromagnet 111 and then attaches the electromagnet holder 200 to the pair of horizontal supports 130, 110).

4, the operator moves the first fixing plate 150 to the rear vertical plate 123, stops the fixing plate at a predetermined position, and then moves the upper surface of the rear vertical plate 123 and the first fixing plate The fixing jig 170 is manually pushed toward the indefinite workpiece 200 along the guide hole 171 of the fixing jig 170 into which the fixing rods 123b and 152 installed on the upper surface of the fixing jig 170 Is brought into close contact with the outer surface of the irregular shaped workpiece 170 (S130).
