Description of the Related Art As shown in FIG. 15 (a), in a conventional curved guide device, a curved track rail 2 is assembled on a base (base mounting surface) 1 and rolling elements are mounted on the curved track rail 2. The sliding body 8 is slidably guided through 10. As shown in Figs. 15 (b) and 15 (c), when assembling the curved track rail 2 on the base 1, the pins 11 are planted at intervals on the arc line on the base 1. , Place the short curved track rail 3 gently on the base 1. Inside these short curved track rails 3 to these pins 11 (Fig.
15 (b) and (c) (left side) are brought into contact with each other, the ends of the short curved track rails 3 are brought close to each other at the connecting portion (joint portion) 9, and a predetermined space is provided between them. A curved track rail 2 having a track length is constructed. Next, on the base 1, at a position outside the short curved track rail 3 (right side in FIGS. 15 (b) and 15 (c)),
A plurality of lateral push bolt blocks 12 are placed, and the tips of the lateral push bolts 13 screwed into the screw holes of the lateral push bolt blocks 12 are brought into contact with the outer surface (anti-reference surface) of the curved track rail 2. Insert the mounting bolt into the stepped hole 14 of the curved track rail 2, lightly screw the mounting bolt into the screw hole (preformed screw hole) of the base 1, and temporarily tighten the curved track rail 2 to the base 1. . The block 12 for lateral push bolts is fixed to the base 1, and the lateral push bolts 13 are screwed in so that the tips of the lateral push bolts 13 are in close contact with the outer reference surface of the curved track rail 2 on average. Stepped hole
There is an "play" between 14 and the stepped bolt, and the center of the stepped hole 14 and the center of the stepped bolt can be displaced and screwed together.
Using a measuring jig (not shown), a dial gauge is applied to the outer corner of the curved track rail 2 and the circularity of the arc is measured. As a result of the measurement, the short curved track rail 3 is removed and reattached to the portion where the roundness is extremely poor. By repeating these operations, the curved track rail 2 is accurately positioned on the base 1, and the mounting bolts are tightened in order from the center to both ends with a torque wrench to fix the curved track rail 2 to the base 1. .

Therefore, when only one short curved track rail 3 is used, it is sufficient to fix the short curved track rail 3 to the base 1 with a mounting bolt without measuring an arc (measurement of circularity). However, since a plurality of short curved track rails 3 are usually used as a curved track rail 2 having a predetermined track length, as described above, when the curved track rail 2 is mounted on the base 1. In addition, it is necessary to repeat the measurement of the roundness at the assembly site of the curved track rail 2 to perform positioning, which requires a lot of time and labor for assembly.

組付方法のように変更することができる。FIG. 4D shows a state in which the fastening rail composite body 28 is fixed to the substrate 1. The same number of screw holes 29 as the insertion holes 22 are formed on the substrate 1 at predetermined positions (positions substantially matching the insertion holes 22). The fastening rail composite body 28 is placed at a predetermined position of the substrate 1, that is, a position where the insertion hole 22 and the screwing hole 29 have substantially the same axis, and the fastening rail composite body 28 is temporarily tightened so as not to move. The mounting bolts 21 are inserted from the left end of the curved track rail 2 into the even-numbered stepped insertion holes 19 and the insertion holes 22 of the curved mounting board 4 and screwed into the screw holes 29. In this way, the fastening rail composite body 28 is fixed to the substrate 1. As described above, the connecting portions 9 of the short curved track rails 3 and the joints 30 of the curved mounting boards 4 are displaced from each other in the longitudinal direction, and they do not overlap. Also the connecting bolt
25 ・ When tightening the mounting bolt 21, it is desirable to use a torque wrench to make the tightening force approximately constant. (These points are the same in other assembling methods.) Note that after temporarily fastening the fastening rail composite 28 to prevent it from moving,
Insert a drilling device such as a drill into the even-numbered stepped insertion holes 19 and the insertion holes 22 of the curved mounting board 4 from the left end of the curved track rail 2, and place the board at substantially the same axial line position as the stepped insertion holes 19 and the insertion holes 22. It is also possible to form a screwing hole 29 having a predetermined depth on the surface of 1. In this way, the assembly of the curved track rail of the curved guide device by the first assembly method of the first embodiment is completed. First
The stacking method of the assembling method is roughly divided into two works of forming the fastening rail composite body 28 and fixing the fastening rail composite body 28 to the substrate 1. Since the same kind of work is performed collectively, it will be described later. The work efficiency is extremely higher than that of the assembling method described above, and the curved track rail 2 can be assembled in a relatively short time. The length of the short curved track rail 3 and the curved mounting board 4, the number of holes, and the distance between the holes can be appropriately changed. However, it is desirable that the connecting bolts 25 and the mounting bolts 21 are alternately arranged, and that the fastening of the short curved track rail 3 and the curved mounting board 4 uses two or more connecting bolts 25 in any combination. Further, in the first assembling method, instead of the mounting bolt 21, a mounting bolt 38 according to a fourth assembling method described later is adopted, and holes related to the mounting bolt 38 are provided in the fourth mounting method.
It can be changed like the assembling method.

By connecting the ends of the curved track rails to each other, a curved track rail having a predetermined track length is formed, and a curved mounting board is disposed between the base and the curved track rail in an overlapping manner. The side portion and the curved track rail fastening reference surface of the curved mounting board are brought into contact with each other, and a through hole or a screw hole for fastening is formed in the curved track rail and the curved mounting board. The short curve track rail is arranged at a position not overlapping the connecting portion at the end of the row, and the curve track rail is fastened to the base by the mounting bolts. Therefore, by using the curved mounting board, a plurality of short curved track rails with the same configuration as the conventional one can be placed on the base at positions with precise arcs and rail radii without having to measure arcs at the assembly site. It can be used as a curved track rail. Further, according to the present invention, a timing belt with teeth facing the outer surface or the inner surface is arranged on the side of the row of the curved mounting board or the side of the curved track rail, the table is connected to the sliding body, and the table is rotationally driven. A unit is provided, a gear is coupled to the rotary shaft of the rotary drive unit, and the teeth of the gear mesh with the teeth on the outer surface or the inner surface of the timing belt. Therefore, the sliding body and the table can be driven by a simple mechanism.
