- FIG. 21 is an example of a perspective view of the upper surface side of a state in which the first rail and the second rail are connected according to the sixth embodiment;
- a guide device which is one aspect of the present invention, includes a rail.
- a rail is attached to the mounting surface and guides the carriage.
- the first surface is the surface that contacts the mounting surface when the rail is mounted on the mounting surface.
- the rail also has a second surface facing the first surface.
- the first surface and the second surface are surfaces extending in the longitudinal direction of the rail. In addition, the second surface does not have to be parallel to the first surface.
- the rail has a through hole.
- the through hole has a center axis perpendicular to the first surface and the mounting surface. A tool, for example, can be passed through this through hole.
- the rail has a recess that is an opening on the first surface side of the through hole and that is recessed from the first surface toward the second surface. That is, the through hole is open at the recess. Since the recess is recessed from the first surface, a space surrounded by the recess and the mounting surface is formed when the rail is attached to the mounting surface.
- the recess includes a third surface orthogonal to the first surface and orthogonal to the width direction of the rail.
- This third surface is a surface formed in the side surface direction of the rail among the surfaces forming the recess.
- This third surface may be a surface parallel to the side surface of the rail.
- the recess accommodates an eccentric portion that rotates eccentrically with respect to a reference axis orthogonal to the mounting surface and applies force to the third surface in the width direction of the rail.
- the reference axis is a rotation axis provided on the mounting surface.
- the eccentric portion pushes the third surface by contacting the eccentric portion with the third surface.
- the rail is elastically deformed and bent by the force with which the eccentric portion presses the third surface. Since the eccentric portion is eccentric with respect to the reference axis, the force pressing the third surface can be adjusted by adjusting the rotation angle. Therefore, the bending of the rail can be corrected by rotating the eccentric portion.
- the through hole and the recess are formed such that the diameter of the through hole is shorter than the length of the recess in the width direction. Therefore, since the diameter of the through hole is relatively small, for example, when a tool for rotating the eccentric portion is inserted into the through hole, the tool can be easily inserted into the eccentric portion. Therefore, it is possible to rotate the eccentric portion quickly, and elastically deform the ends of the rails, thereby reducing the displacement of the joints of the rails.
- the eccentric portion may be the head of an eccentric bolt that rotates around the reference axis.
- the threaded portion of the bolt is screwed into the mounting surface. If it is an eccentric bolt, it will not come off even if it is attached to the mounting surface in advance, so the work can be simplified. Also, if there is a tool for turning the eccentric bolt, the bending of the rail can be corrected relatively easily.
- the recess may be formed up to at least one end of the rail. Then, for example, it becomes possible to store the eccentric portion in the recess while moving the rail in the longitudinal direction, so that the work can be simplified.
- the through-hole may be formed closer to the end of the rail than the mounting hole through which the bolt for fixing the rail to the mounting surface is passed. For example, if force is applied to the third surface by the eccentric part to correct the bending of the rail, and the rail is attached to the mounting surface with a bolt passed through the mounting hole, the rail can be fixed in a state where the bending of the rail is corrected. can be done. In addition, since the through hole is provided on the end side of the rail, even if there is a step with another rail when connecting to another rail, the rail can be bent in a direction that eliminates the step by rotating the eccentric part. be able to.
- the through holes may be formed between a plurality of mounting holes through which bolts for fixing the rail to the mounting surface are passed.
