<Example> As shown in FIG. 1 showing the front shape of an example in which the high-rigidity machine tool of the present invention is applied to a plano miller, and FIG. 2 showing the cross-sectional shape in the direction of -
A pair of front and rear guide rails 12a and 12b are formed on the bed 11 and extend in the front and rear direction.
A workpiece 13 is placed on top of the workpiece 1 . Columns 15a, 15b, which are slidable in the front and rear direction along the front and rear guide rails 12a, 12b, are screwed into a pair of column feed screws 14a, 14b arranged along the front and rear guide rails 12a, 12b, respectively. The pair of columns 15a, 15b reciprocates on the bed 11 in the front-back direction by the synchronized rotation of these column feed screws 14a, 14b connected to a drive motor (not shown). A bridge 16 is spanned over the upper ends of the columns 15a and 15b, and a saddle feed screw 17 is disposed along the bridge 16.
A saddle 18 that is slidable in the left-right direction along the bridge 16 is screwed into the seat. The saddle 1 is moved by the operation of the saddle drive motor 19 attached to one end of the bridge 16 and connected to the saddle feed screw 17.
8 reciprocates in the left-right direction while being held by the bridge 16. A ram support 21 is supported on the saddle 18 so as to be movable up and down via a pair of left and right hydraulic cylinders 20a and 20b, and a ram 23 with a tool 22 removably attached to the lower end of the ram support 21 moves up and down. Can be installed freely.
The ram 23 has a bracket 2 on the ram support 21.
A ram feed screw 26 extending from a ram drive motor 25 provided through the ram drive motor 25 is engaged with the ram feed screw 26, and the ram 23 is moved up and down with respect to the ram support 21 by the operation of the ram drive motor 25. . Further, a pair of skirt portions 27a, 27b that are pressed against the upper surface of the workpiece 13 are integrally protruded from the lower surface of the ram support 21 facing the workpiece 13, and these skirt portions 27a,
27b is the aforementioned fluid pressure cylinder 20a, 20b.
The workpiece 13 is pressed together with the ram support 21 by the operation of the ram support 21 . Fluid pressure cylinders 20a, 20b
If a sufficient stroke cannot be obtained, the skirt portions 27a, 2 may be
Since there is a possibility that the skirt parts 7b may not reach the upper end surface of the workpiece 13, these skirt parts 27a and 27b may be prepared in advance in various sizes so that they can be replaced with respect to the ram support 21 as necessary. It is valid.

The position of the tool 22 with respect to the workpiece 13 can be arbitrarily changed by changing the driving positions of the columns 15a, 15b, the saddle 18, and the ram 23. Also, when machining the workpiece 13 with this tool 22, the fluid pressure cylinders 20a, 20b are operated to attach the skirt portions 27a, 27b to the workpiece 13.
The ram support 21 is pressed through the ram support 21, and the ram drive motor 25 is operated in a state where these are integrated to give cutting feed to the tool 22. In this state, the workpiece 13 and the ram support 21 are integrated, so the workpiece 13 itself takes charge of a part of the cutting reaction force, and the ram support 21, the saddle 18, etc. that supports it, There is no need to increase rigidity too much.

It is also possible to apply this technique to the bridge 16, bridge 16, etc.

<Effects of the invention> According to the highly rigid machine tool of the invention, the ram support is pressed against the workpiece through the skirt portion, and machining is performed with the workpiece and the ram support integrated. Therefore, the workpiece itself can be considered as a part of the machine structure, and the rigidity of other movable bodies such as the saddle that supports the ram support can be designed to be small. As a result, the machine tool can be made smaller and lighter, leading to a reduction in manufacturing costs.
