As an example of this type of machine tool, the column for the spindle head moves in the X-axis (left and right) and Z-axis (front and back) directions, and the spindle head located on the table side of the column moves in the Y-axis (up and down). ) is known. To explain this configuration with reference to FIG. 1 showing a conventional machine tool of this type, the column 27 is connected to the column guide section 2.
4 and moves along the guide surface 25 on the saddle 23 in the Z-axis direction. The saddle 23 then moves along the guide surface 22 on the bed 21 in the X-axis direction. Therefore, the column 27 placed on the saddle 23 can itself move in the X-axis direction as the saddle 23 moves in the X-axis direction. Furthermore, the spindle head 34, which is provided on the column 27 so as to be slidable in the vertical direction (Y-axis direction), moves together with the column 27 in the X-axis and Z-axis directions, and also moves along the column 27 in which it is installed.
It is configured to move in the Y-axis direction at X and Z positions of 7.

In the above-mentioned movement, in the conventional machine tool of this type shown in FIG .
is narrower than the column width, and the distance H1 in the height direction between the guide surface 25 and the tool spindle 28 is large. The bending moment based on the force applied between the guide surface 25 and the workpiece increased, weakening the rigidity of the guide surface 25, and making it impossible to improve machining accuracy. Furthermore, since the height from the floor surface 13 to the top surface of the table is set to a predetermined value in order to ensure workability, the lower limit position of the movement range of the spindle and, by extension, the height position of the bottom surface of the column 27 is also restricted. Therefore, the bet 21 and the saddle 23
Since the thickness of the seat is also limited, sufficient rigidity of the bed 21 and the saddle 23 cannot be ensured.

があつた。 Conventionally, since there was a guide surface at the bottom of the column, it was not possible to secure a space at the bottom of the column 27, which made it difficult to sweep away the chips due to the flow of chips and cutting fluid, making it difficult to automatically dispose of the chips. However, there were problems such as deterioration of machining accuracy due to thermal deformation due to chips accumulated on the guide surface and other parts of the machine tool.

This invention was made in order to solve the above problems, and its purpose is to improve the rigidity by guiding and sliding the column at a lateral position of the column, and to dispose of chips on the lower side of the column. The object of the present invention is to provide a machine tool such as a column-moving machining center that can improve the performance.

In order to achieve the above object, the present invention provides a column-moving machine tool including a column 7 in which a spindle head 14 is provided so as to be movable up and down, and a spindle head 14 disposed at a position higher than the bottom of the column 7 and on both sides of the column 7.
A guide section 4 in which the column 7 is movable back and forth toward the workpiece, and a reference guide section 5 corresponding to the guide section 4.
and a column guide member 3 having a concave portion between the reference guide portions 5 for accommodating the lower part of the column 7.

According to the present invention, since the guide portions corresponding to the reference guide portions of the column guide members are provided at a position higher than the bottom of the column and on both sides of the column, the guide width of the column guide members is widened, and the guide portions corresponding to the reference guide portions of the column guide members are provided. The distance in the height direction between the part and the tool on the spindle becomes extremely small.

ーである。 First, to explain the configuration, as shown in FIGS. 2 and 3, a guide surface 2 is installed on a base 1 in parallel to the X-axis direction, and on this guide surface 2 there is a column guide member. A saddle 3 is placed so as to be movable in the X-axis direction, and a column 7 is placed on the saddle 3 via a guide part 4 so as to be movable in the Z-axis direction. In a machine tool such as a column-moving machining center in which the spindle head 14, which has a tool on the table side from the front side, is arranged so as to be movable in the Y-axis direction, the guide part 4 that supports the column 7 is placed on the table side from the front side of the column. It is fixed to both sides of the column 7 near the height of the main shaft 8 that holds the tool so as to be parallel to the Z-axis direction. The reference guide portion 5 of the saddle 3, which supports the column 7 via the guide portion 4, is arranged horizontally at a position close to the main shaft 8, as shown in the figure. This arrangement allows the saddle 3 to have a chip receiving portion 9 with a sufficient slope at the bottom of the column 7,
In addition, this receiving portion 9 is configured to ensure sufficient space. A Z-axis screw 6 for moving the column 7 in the Z-axis direction is arranged on the inner surface of the saddle 3 inside the lower end of the column 7 in parallel with the reference guide part 5. Reference numeral 11 denotes a chip receiver attached to the front surface of the base 1 in the downstream direction of the chip receiver 9. Reference numeral 12 denotes a slide cover that movably covers the sliding portion of the guide portion 4 around the saddle 3.

の剛性を確保することができる。 With the above configuration, the reference guide part 5 is arranged on both sides of the tool spindle 8 which is closer to the table than the front of the column, so the guide width L of the saddle 3 becomes wider than before, and at the same time, the reference guide part 5 Since the distance H in the height direction between the tool on the spindle 8 and the tool on the spindle 8 is also minimized, the bending moment generated between the tool on the spindle 8 and the workpiece on the table is small, that is, H 1 compared to the conventional case. /L 1 >H/L. Thereby, the rigidity of the reference guide portion 5 can be increased. Furthermore, by making the bed and saddle sufficiently thick without changing the height of the table, the rigidity of the bed and saddle can be ensured.

自動処理が円滑良好にできるものである。 Incidentally, since the height of the saddle 3 is also increased due to the above, it becomes possible to store the Z-axis screw 6 on one side inside the lower end of the column 7, and the central lower part of the column 7 is opened. There is no risk of chips accumulating on the reference guide or Z-axis screw.
Further, there is no problem even if a sufficient amount of cutting agent or the like is poured.
Therefore, the cooling effect during processing on the main spindle 8 can be enhanced and wear and tear can be drastically reduced. Also, the reference guide section 5
By increasing the height, the space under the column 7 becomes larger, and as a result, the inclined surface of the chip receiving part 9 is also made larger, making it easier for chips and cutting fluid to flow toward the chip receiving part 11. Problems such as thermal deformation caused by chips are also eliminated, so automatic processing for sweeping out chips can be performed smoothly and efficiently.

As explained above, the present invention arranges guide parts for supporting the column on both sides of the column,
By arranging the reference guide parts with which this guide part slides on both sides of the tool spindle, the guide width becomes wider, and the tool spindle is located close to the virtual horizontal plane that includes the reference guide parts, allowing the cutting point of the tool tip to Since the distance from the column guide part is short, and the saddle that guides the bed and column can be made sufficiently thick, the rigidity of each part of the machine tool, such as the reference guide part for the column, the bed and the saddle, can be increased. The accuracy of processing is improved and it is possible to guarantee the production of good quality products at all times, and the height of the table (not shown) is maintained as before, resulting in good workability.
In addition, automatic processing for sweeping out chips becomes smoother, and water treatment related to chips can be greatly improved.
This has the effect of greatly contributing to unmanned operation of this type of machinery and labor saving.
