DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a linear sliding device having a slide unit that linearly slides on a track rail.

[0002]

2. Description of the Related Art Conventionally, a linear guide for guiding a linear sliding operation of various machines has been composed of a track rail as a guide rail and a slide unit sliding on the track rail. The slide unit is mounted slidably and without backlash so as to straddle the track rail and sandwich the side surface of the track rail from both sides. Furthermore, the mounting surface, which is the outer surface of the slide unit, is formed parallel to the upper surface of the track rail.

[0003]

In the case of the above-mentioned prior art, the mounting surface of the slide unit is only a surface parallel to the upper surface of the track rail. For example, the mounting surface of the slide unit is perpendicular to the mounting surface provided horizontally. When a member having a surface to be mounted is to be mounted, the mounting attitude of the track rail itself must be changed, and the mounting direction of the member mounted on the slide unit is limited.
Furthermore, since the track rail is fixed to the frame material and used, the sliding operation is performed in a state where the slide unit is exposed from the frame material.
Interference with other members easily occurred.

[0004] The present invention has been made in view of the above-mentioned problems of the conventional technology, and allows a simple configuration to select the mounting posture of an external member to be mounted and prevent interference with other members. It is an object of the present invention to provide a linear sliding device that hardly occurs and has high safety of a sliding operation.

An embodiment of the present invention will be described below with reference to the drawings. The linear sliding device of this embodiment includes a linear metal track rail 10 for guiding linear sliding operation portions of various devices such as a transport device and a feed device, and a slide unit that slides on the track rail 10. 12 are provided. Further, there is provided a frame member 14 which is an extruded shape of an aluminum alloy and accommodates the track rail 10 therein. The frame material 14 is used for the track rail 10.
The rectangular prism having a side surface parallel to the longitudinal direction is formed in an external shape in which a portion from a corner to the center of both side surfaces is cut in the longitudinal direction.

A U-shaped groove 16 is formed in the longitudinal direction from one of the cut corners of the square prism to the diagonal corner, and the bottom surface 16 a of the groove 16 It is formed at an angle of 45 degrees with respect to two outer surfaces orthogonal to each other. The bottom surface 16a is a track rail mounting surface, and the track rail 10 is mounted on the bottom surface 16a so as to protrude in the corner direction of the virtual square prism. The track rail 10 is fixed to the bottom surface 16a of the groove 16 with bolts and nuts (not shown).

The slide unit 12 includes a frame member 1.
A mounting member 20 having two surfaces 20a and 20b flush with the two side surfaces 4 is fixed. Therefore, the side surfaces 20 a and 20 b of the mounting member 20
It is provided at 5 degrees. Then, on the side surfaces 20a and 20b of the mounting member 20, in the longitudinal direction of the frame member 14,
Each of the T grooves 22 is formed. A cylindrical rubber cushioning member 24 is fixed to both ends of the slide unit 12.

At both ends of the frame member 14, end members 26 and 27 in the form of a square metal block are fixed as shown in the figure. As shown in FIG. 3, a grease hole 28 for supplying grease to the slide portion 13 of the slide unit 12 is formed in one end surface member 26.
8 is connected to a grease injection port 30 via a conduit 29. A grease receiving port 32 connected to the grease inlet 30 is provided at one end of the slide unit 12.

In the linear sliding device of this embodiment, the frame member 14 can be used as it is as a structural material of various devices, or can be used as a support for a linear sliding portion, and the slide unit provided in the frame member 14 can be used. As shown by the imaginary line in FIG. 2, a desired mounted member 34 is fixed to the twelve mounting members 20 with bolts 36 and nuts 37 or the like. The nut 37 is inserted into and held in the T groove 22. At this time, the mounting posture of the mounted member 34 may be in any direction of the mounting surfaces 20a and 20b.
