手間取るといつた欠点がある。[Detailed description of the invention] This invention relates to a lathe. In order to make the tool rest moveable toward and away from the main shaft, a slide bed is usually provided around the main shaft along the X-axis, Y-axis, or Z-axis, and the tool rest is provided on the slide bed.
However, in the structure that uses a slide bed as described above, the slide bed is located near the main shaft, and the falling of chips is obstructed by the slide bed, resulting in poor chip collection efficiency and damage to the slide bed itself. The manufacturing cost is high, and during assembly, it is difficult and time-consuming to adjust the reference level using a gib.

Two through holes 5 and 6 are opened. Support plates 8 are provided at both ends of the machine base 1, the position of which is adjusted using a jig 7, which will be described in detail later, and then welded. A cross slide 9 is slidably inserted into and supported by guide shafts 3 and 4 extending through guide shafts 5 and 6. The cross slide 9 supports the ball screw 11 by screwing an internal female screw portion (not shown) into the ball screw 11 which is parallel to the guide shafts 3 and 4 and passed between the support plate 8 and the machine stand 1. When rotated by a servo motor 12 on the plate 8, it moves in parallel from side to side. Reference numeral 13 denotes a support frame which also serves as a sprocket for interlockingly connecting the servo motor 12 and the end of the ball screw 11, and a case for the chain 14. Note that 15 and 16 are bearings for the guide shafts 3 and 4, respectively, and in this example, they are static pressure bearings.

なすことができる。 That is, as shown in FIG. 4, if the through holes 5 and 6 opened under the head stock portion 1a of the machine base 1 are made slightly larger than the diameters of the guide shafts 3 and 4, respectively, the support plate 8 is temporarily fixed by tightening the bolt 7b on a position adjustment jig 7 consisting of a nut 7a and bolt 7b protruding from the machine base 1, and then adjust each position adjustment jig 7 to support the position adjustment jig 7. The guide shafts 3 and 4 placed on the plate 8 can be easily brought to an appropriate height and aligned along an accurate horizontal plane.

に固定する。 Once the resin concrete has hardened and the guide shafts 3 and 4 are securely fixed to the machine base 1, the position fixing pin 33 is pulled out, the support plate 8 is removed, and both ends of the guide shafts 3 and 4 are opened. Then, the cross slide 9 assembled in a separate process is inserted into the guide shafts 3 and 4 from the side. After inserting the cross slide 9, the support plate 8 is again fitted to both ends of the gear shafts 3 and 4, and this time it is welded or bolted to the machine base 1.
Regarding the assembly of the main shaft 2 to the machine base 1, in the same way as the assembly of the guide shafts 3 and 4 to the machine base 1,
The through hole 35 opened on the front and rear surfaces of the machine base 1 is made to have a slightly larger diameter than the main shaft 2 to be inserted, and the main shaft 2 to be inserted is formed into a cylindrical unit body, so that the main shaft 2 becomes the unit body. is inserted into the through hole 35, and the main shaft 2 is adjusted to a proper position and posture with respect to the machine base 1 using a jig similar to the position adjustment jig 7, and then
The same resin concrete as mentioned above is poured into the closed space around the main shaft 2 in the machine base 1, hardened, and the machine base 1

る。 As described above, the assembly of the cross slide 9 and the main shaft 2 to the machine base 1 is completed.
If fixing to the lathe is done by filling a hardening agent such as resin concrete, the assembly process is further simplified, and since concrete has good vibration damping properties, it is possible to obtain a lathe with less vibration during operation. I can do it.

振動減衰性が向上されている。 As is clear from the above description, the lathe according to this invention has a tool rest mounted on a cross slide that is movable along a guide shaft, and the guide shaft is mounted on a support member whose position can be adjusted with respect to the machine base. Because it has a supported structure, there is no need for troublesome adjustments such as adjusting the gib when using a slide bed, and the position and inclination of the guide shaft can be easily adjusted by adjusting the position of the support member, which reduces the time required for assembly. Less man-hours. In addition, since a slide bed is not used, there are no obstacles around the spindle that prevent the chips from falling, increasing the recovery rate of chips. Also, since a guide shaft is used instead of the slide bed, the overall cost of the lathe can be reduced. . Furthermore, the guide shaft, which supports the heavy cross slide, is fixedly supported at its center by a hardening agent filled in the main shaft head stock, so that the support plates on both sides are not as strong. Even if it is not expensive, the lathe as a whole can have high rigidity and strength. Furthermore, since the support plate can be made of a plate material with relatively low strength, it is easy to adjust the position of the guide shaft, and the guide shaft is fixed within the head stock by filling with a hardening agent, which also makes assembly work easier. This simplifies the process and improves vibration damping properties.
