Accordingly, since the slider 25 and the slider 25 are attached to different sides, the force is mutually complemented at the portions of the first linear guide 21 and the second linear guide 22, and the excellent rigidity is obtained. This enables accurate guidance. Therefore, the ram 9 and the cross saddle 5 rarely pick up vibrations of cutting of the tool 14 even during heavy cutting, and hardly cause chattering or resonance.
- FIG. 6 relates to the operation description (1) of the ram guide device 1 of the machine tool according to the present invention, the operation description (2) of the top mounting type saddle 51 according to the conventional example, and the front mounting type. (3) of operation
- the spindle 13 of the machining head 8 is in the ascending limit as the origin position and is located at the same height. 6 (1) and 6 (2), the cross beams 4 have the same height. However, in FIG. 6 (3), since the saddle 52 is attached to the front surface of the cross beam 4, the cross beams 4 have the same height. The beam 4 is provided at a higher position.
- the ram 9 is a long section from the upper end to the lower end of the vertical portion 7.
- the first linear guide 21 and the second linear guide 22 are supported by the first linear guide 21 and the second linear guide 22, they are hardly affected by vibration during heavy cutting, and do not resonate and are stably supported. Therefore, when the spindle 13 is at the origin position (upward limit) or a position close to the origin position, the slider 25 of the first linear guide 21 and the slider 26 of the second linear guide 22 are separated from each other by a long distance. Since the ram 9 is supported, the ram 9 is held more firmly and serves to prepare for powerful cutting.
- the ram 9 has lost support at the part above the saddles 51 and 52 and is supported only in the section where the saddles 51 and 52 exist. Yes. For this reason, the ram 9 and the saddles 51 and 52 are likely to resonate by picking up vibrations of cutting during heavy cutting and cannot withstand powerful cutting.
- the maximum overhang amount is the lower end of the lower slider 25 among the upper and lower sliders 25 at the origin position (upward limit) of the ram 9 as shown in FIG. To the lower end of the rail 24.
- the length L at that time is substantially the same as the maximum descending amount of the ram 9 in the Z-axis direction.
- the magnitude relationship of the overhang amount is length L1 ⁇ length L2, L3.
- the amount of overhang is small even when moving between the same positions. Therefore, when a large cutting resistance force is applied to the tool 14 at the tip of the spindle 13 during machining, the moment at that time can be suppressed to be small compared to the conventional type by a small overhang amount.
- the length L1 is generally about 600 to 800 [mm].
- both overhang amounts do not change.
- the length of the left and right columns 3 is shortened because the cross beam 4 is low, so the strength of the columns 3 in FIGS. 6 (3) column 3 becomes easier.
- FIG. 7 shows that the third linear guide 23 for guiding the ram 9 in the vertical direction is incorporated between the both side surfaces of the ram 9 and the inner surfaces of both side surfaces of the box 18 in the embodiment of FIG.
- the ram 9 is movably attached only in the vertical direction by two linear guides, that is, a first linear guide 21, a second linear guide 22, and a third linear guide 23.
- the movement in the Y-axis direction can be more reliably regulated on the front side of the ram 9.
- FIG. 8 shows that the second linear guide 22 is incorporated between the both side surfaces of the ram 9 and the inner surfaces of both side surfaces of the box 18 in the embodiment of FIG.
- An example is shown in which the ram 9 is movably attached only in the vertical direction by two linear guides 22 and a third linear guide 23.
- the first linear guide 21 and the second linear guide 22 have different orientations. Therefore, when assembled without play, obstacles are likely to occur in the vertical movement of the ram 9. According to the embodiment of FIG. 8, such inconvenience is less likely to occur.
- FIG. 9 shows that the third linear guide 23 is incorporated between the both side surfaces of the ram 9 and the inner surfaces of both side surfaces of the box 18 in the embodiment of FIG.
- An example in which the ram 9 is attached to be movable only in the vertical direction by the second linear guide 22 and the third linear guide 23 is shown.
- the feed screw unit 35 for raising and lowering the ram 9 (in the Z-axis direction) is disposed as two units in the space on both sides of the ram 9 inside the box 18 as illustrated in FIG. As illustrated in FIG. 9, the unit is arranged as a unit in the space on the back side of the ram 9 inside the box 18. 3 and FIG. 7, the lead screw unit 35 is incorporated as two units or one unit according to the example of FIG. 8 or the example of FIG.
- the two-unit feed screw unit 35 is very advantageous in terms of rigidity and speed compared to a general unit of one unit.
- the ram guide device 1 for a machine tool according to the present invention is used for a portal machine tool 2.
- the portal machine tool is not limited to a machining center, but can be applied to machining machines such as drilling, planing, and milling. it can.
