【Example】

 Hereinafter, the present invention will be described with reference to the illustrated embodiments.

The present invention will be described by giving the same reference numerals to the same components as those of the above-described specific example.

In FIGS. 1 to 3, reference numeral 1 is a machine frame in a wire electric discharge machine. The machine frame 1 is provided with a reel 2 around which a wire electrode W is wound. The wire electrode W is wound around the pair of supply rollers 5 via the guide rollers 3 and 4. An upper guide 6 is attached to the machine frame 1 below the two supply rollers 5 so as to guide the wire electrode W downward so that the angle of the wire electrode W can be adjusted. A pair of guide rails 7 are horizontally laid on the machine frame 1. Further, a moving table 8 is provided on each of the guide rails 7 so as to be movable in the X-axis direction and the Y-axis direction, and a work 9 as a workpiece is detachably mounted on the moving table 8. It is placed. Furthermore, on the moving table 8 directly below the upper guide 6, a lower guide 10 and a pair of discharge rollers 11 are provided so as to guide the wire electrode W downward so that the angle of the wire electrode W can be adjusted. The wire electrode W is stretched between the upper guide 6 and the lower guide 10 and the discharge rollers 11 so as to be perpendicular to the work 9 and inclined.

On the other hand, in FIGS. 1 and 2, a pair of suction gauge block bodies 20 are detachably provided on a side surface 9a of the workpiece 9 as a surface to be processed. Each vertical reference plane 21 is formed on the side surface of the body 20. A magnet 22 is embedded in the middle of the side surface of both suction gauge block bodies 20, and a grip portion 20a is formed on the other side surface of both suction gauge block bodies 20. Further, the wire electrode W is stretched between the suction gauge block bodies 20 and the vertical reference planes 21 so that the vertical and tilt angles of the work 9 are detected and set while discharging. Has been done.

The operation of the present invention will be described below.

Therefore, when the work 9 is placed between the upper guide 6 and the lower guide 10 of the machine frame 1 and the work 9 is subjected to electric discharge machining by the wire electrode W, a pair of work surfaces 9 a of the work 9 are formed. The suction gauge block body 20 is separated from the suction gauge block body 20 by the magnet 22. Next, the wire electrode W is brought into contact with the vertical reference planes 21 of both suction gauge block bodies 20 to discharge the workpiece 9 uniformly and detect the verticality and inclination angle of the workpiece 9 to determine the workpiece 9 in a predetermined manner. Set to the angle.

That is, as shown in FIG. 1, the work angle detection setting operation for detecting the vertical 7 and the inclination angle of the work 9 is performed by a pair of suction gauge block bodies 20 on the side surface 9 a of the work 9 as a work piece. Are separated from each other by being attracted to the surface 9a to be processed by the magnet 22, and then the wire electrodes W are brought close to the respective vertical reference surfaces 21, and a voltage is applied to the wire electrodes W, thereby W becomes a discharge state, and the work of the wire electrode W is performed by moving the upper guide 6 so that the discharge state comes into contact with the entire surface of each of the vertical reference planes 21 to generate a uniform discharge (spark). It is assumed that the vertical and inclination angles of 9 can be adjusted.

Finally, the moving table 8 is moved in the X-axis direction and the Y-axis direction, both the suction gage block bodies 20 are removed from the work 9, and the moving table 8 is moved in the X-axis direction and the Y-axis direction. The wire electrode W is moved and brought into contact with the side surface 9a of the work 9, and then corona discharge machining is started by applying a voltage to the wire electrode W by electric discharge machining of the work 9, thereby finishing the work 9. Apply processing.

As described above, the present invention detects the adjustment of the inclination angle of the wire electrode W to detect the discharge processing position of the work 9 without causing the streak-like scratch due to the discharge on the side surface 9a of the work 9. It is something to set.

Although the present invention has been described using the pair of suction gauge block bodies, it is needless to say that three or more suction gauge block bodies may be used within a range not changing the gist of the present invention.
