Abstract

PURPOSE:To realize an electric discharge machining process with a high degree of accuracy, with the use of an electric machining device for electric discharge, by laying saddle guide rails along the top edges of the side vertical surface of a bed to reduce the deflection of the bed due to the shift of the center gravity thereof caused by a saddle. CONSTITUTION:Saddle guide rails 3 on which a saddle is movably set are laid on the top surface 1a of a box-like bed 1 having bed side plates 1b suspended from both bed side edges of the top surface 1a of the bed 1, along both bed side edges 1c. Since the saddle guide rails 3 are laid along the side edges 1c, loads applied to them are transmitted in the surface direction so that the rigidity in the vertical direction is remarkably enhanced, and since the cross-section of each side plate 3 is uniform in the direction along the rail 3, the amount of deflection of the bed 1 is less even if the loading point is shifted, thereby an electrical discharge machining process may be realized with a high degree of accuracy.

The workpiece 7 can be positioned at any position on the X-Y plane, and the processing head 8 is constructed so that it can freely move up and down in the Z direction. Furthermore, the internal structure of the bed is constructed by arranging the reinforcing ribs 11 perpendicularly to the installation direction of the side kite rail B, that is, the Y direction, as shown in the second (N1). There is.

Machining utilizes the electric discharge phenomenon between the workpiece 7 and the machining nozzle 8, and it is necessary to maintain an appropriate gap between the two. The desired shape is finished by feeding the workpiece in the X-Y plane while holding it, but at that time, the center of gravity of each of the workpiece 7, table 6, and saddle 6 moves. As mentioned above, reinforcing ribs 11 are arranged on the processing machine neck 1 supporting these components for reinforcement.

As a result, the deformation of the bed is transmitted to the processing machine head 8 through the column 2, causing unexpected relative displacement between the head and the workpiece. There are limits to accuracy.

である。[Practice of the invention v11] Next, an example of the present invention will be described with reference to the drawings.
In Fig. 4 1, a box-shaped bed 1 has bed side plates 1b vertically disposed on both sides of the bed top surface 1a, and the bed side edges 1c and VC formed by the top surface and side plates are connected to a saddle 4 ( A saddle guide rail 6 is provided on the top surface of the bed for movably loading and unloading (not shown).

来構造の撓みδ１のほぼ２分の１に減少している。Therefore, according to the present invention, even if the bed 1 is simply constructed by combining thin plates, even if the constituent plates have low rigidity in the out-of-plane direction, they have high rigidity in the in-plane direction. Bend the guide rail 6 and bend the upper surface 1a (I
Since it is disposed in contact with the 87 part 1C, the load acting on the guide rail is transmitted in the in-plane direction of the bed side plate 1b, whereas the rigidity under the guide rail 6 of the conventional structure is low. As a result, the rigidity in the vertical direction is significantly improved, and since the side plate has a uniform cross section in the direction along the kite rail, even if the load point moves, the deflection of the bed 1 will not change suddenly unlike in the conventional structure. Therefore, the saddle 4 always moves on the highly rigid bed side plate 1b, reducing the amount of bed deflection and preventing sudden changes in the amount of deflection. Looking at this from the analysis results shown in FIG. 5, the deflection δ2Fi due to the load 16 is reduced to approximately one-half of the deflection δ1 of the conventional structure described above.
