Guiding device

Abstract

A guiding device where foreign objects do not enter from gaps into a moving block even in an environment where a large amount of dust is present in the air, the gaps being formed by side faces of a track rail and inner faces of a moving block. A guiding device has a track rail and a moving block (20) and is constructed such that the moving block (20) is assembled so as to be movable relative to the track rail with rolling bodies that circulate in rolling body circulation paths in between. Foreign object entry prevention plates (34) are provided in the guiding device, and head ends of the plates are in contact with side faces of the track rail along its length direction. The plate (34) closes at least gaps formed by inner faces of skirt sections on both sides of the moving body (21) of the moving block (20), side-lid inner faces, and track rail side faces.

Description

technical field [0001] The present invention relates to a guide device including a guide rail and a moving block assembled on the guide rail freely through the movement of a rotating body, and particularly relates to a guide device suitable for use in an environment where fine dust is scattered. Background technique [0002] As shown in Figure 1, there is a device that is freely assembled on the guide rail 101 through the relative movement of a plurality of rotating bodies (balls or rollers) (including the situation when the guide rail 101 is fixed and the moving block 102 moves, and the moving block 102 is fixed and the guide rail 101 moves). Guide device on the mobile block 102 . The structure of this guide device is that the moving block 102 has a moving block main body 103 mounted on the guide rail 101 in a straddling state, side covers 104 / 104 installed on both ends of the relative moving direction in a state straddling the guide rail 101, and The state of 101 is insta...

Problems solved by technology

[0004] Although there is basically no problem of foreign matter entering the moving block 102 when using the above-mentioned guiding device as shown in Figure 1 in a general environment, in an environment with a lot of dust like figure 2 As shown, the guide rail 101 is installed on the ceiling 106, and the moving block 102 is assembled on the guide rail 101, that is, when the guide device is used in an inverted state; or as image 3 As shown, the guide rail 101 is installed on the wall surface 107 in a horizontal state, and the moving block 102 is assembled on the guide rai
