Linear Table with an Adjustable Dust-proof Structure

Abstract

A linear table with an adjustable dust-proof structure is locked with a loading rack on each end of a stator by screw, and each end of an elongated sheet-like dust-proof structure is located on each of the two loading racks. As compared to the conventional plate-like dust-proof structure, the weight of the dust-proof structure of the present invention is widely reduced, thus avoiding the problem of structure bending downwards. Moreover, adjusting the distance between the two loading racks can adjust the strain of the dust-proof structure, further preventing the dust-proof structure from bending downwards.

Description

BACKGROUND OF THE INVENTION[0001]1. Field of the Invention[0002]The present invention relates to a linear table, and more particularly to a linear table with an adjustable dust-proof structure.[0003]2. Description of the Prior Art[0004]Generally speaking, a linear table comprises a stator and a runner. The stator includes a linear guideway, along which the runner moves. By such arrangements, when other machines or structure are assembled on the runner, they can utilize the linear table to carry out linear displacement. But the linear table is a high precision machine, if the guideway of the stator is stained with dust or dirt, it will influence the smoothness and precision of the movement of the runner, and even cause the damage of the linear table.[0005]Hence, a linear table with dust-proof structure was developed on the market. As shown in FIG. 1, the linear table comprises a stator 10 and a runner 20. Each end of the stator 10 is disposed with a loading rack 11 located correspond...

Benefits of technology

[0007]The present invention is to provide a linear table with an adjustable dust-proof structure to achieve the first objective of reducing the weight of the dust-proof structure and the second objective of adjusting the strain of the dust-proof structure, synchronously to achieve the objective of preventing the dust-proof structure from bending downwards for the greater torque of the dust-proof structure than the structure strength.

[0008]Hence, with respect to the present invention, each end of an elongated sheet-like dust-proof structure of the present invention is disposed on each loading rack at each end of the stator, and above the runner. By such arrangements, not only the present invention has the same dust-proof effect as the conventional one, but also the thickness of the dust-proof structure is just enough to support the torque caused by weight in the middle portion, so as to prevent the dust-proof structure from bending downwards. So due to the light and thin dust-proof structure, the problem of the dust-proof structure bending downwards caused by greater torque than the structure strength and the disadvantage of difficult design for the excessively great thickness of the dust-proof structure can be solved. In addition, each end of the stator is formed with a positioning piece, and the two loading racks are locked on the two positioning pieces by screw, and the locking direction of the two loading racks corresponds to the direction of the two ends of the dust-proof structure, so that the distance between the two loading racks can be adjusted by screw and the strain of the dust-proof structure can be changed, further preventing the dust-proof structure from bending downwards. Moreover, each side of the dust-proof structure can be mounted with a protection cover, so as to prevent the operator form being cut by the two sides of the dust-proof structure.

Problems solved by technology

But the linear table is a high precision machine, if the guideway of the stator is stained with dust or dirt, it will influence the smoothness and precision of the movement of the runner, and even cause the damage of the linear table.

But most of these conventional dust-proof structures 30 are made by the extrusion molding of aluminum material or made of sheet metal, so the weight of a single dust-proof structure 30 is rather great.

Moreover, the portion of the runner 20, which is assembled with other machines or structures, must be higher than the dust-proof structure 30, but the dust-proof structure 30 is an elongated plate-like element, so the runner 20 must be quite high, thus causing the difficulty of the design and the waste of the space.
