Guiding device

Abstract

The present invention provides a guide device that prevents foreign matter from entering the moving block from the gap between the side surface of the guide rail and the inner surface of the moving block even in an environment where a large amount of fine dust is flying. The structure of the device is provided with a guide rail and a moving block (20), and the moving block (20) is relatively moved freely assembled on the guide rail by the rotating body circulating on the rotating body circulation path; The gap between the inner side of the side skirt part of the block body (21), the inner side of the side cover and the side of the guide rail, and the foreign matter intrusion prevention plate (34) whose top end contacts the side of the guide rail along the length direction.

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] has been like figure 1 The shown moving block is freely assembled on the guide rail 101 through relative movement of a plurality of rotating bodies (balls or rollers) (including when the guide rail 101 is fixed and the moving block 102 moves, and when the moving block 102 is fixed and the guide rail 101 moves). 102 guides. 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 installed to the sealing device 105 / 105 out...

Problems solved by technology

[0004] Although in a general environment like figure 1 As shown, using the above-mentioned guiding device basically does not have the problem of foreign matter entering the moving block 102, but 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 rail 101, that is, when the guide device is used in a wall-mounted state; or as Figure 4 As shown, when the guide rail 101 is installed on the wall surface 107 in a vertical state, and the moving block 102 is assembled on the guide rail 101, that is, when the guide device is used in an upright state, there are foreign objects moving from the side of the guide rail 101 to the wall surface 107. The problem that the gap between the inner surfaces of the block 102 enters the moving block 102 and prevents the smooth rotation of the rotating body (ball or roller) and causes failure
