DETAILED DESCRIPTION OF THE EMBODIMENTS

[0019] Referring to FIG. 1 to FIG. 4, a dust-proof device for a machine tool worktable comprises a stainless steel dust cover 03 arranged on a worktable 01 and a worktable base 06, organ-type dust covers 04 and L-shaped dust-proof plates 11. The worktable base 06 is installed on a machine tool bridge 07 by means of a pair of linear guide rails 02 and a pair of ball screws 10. A U-shaped through groove 15 is milled out in an upper portion of the worktable base 06. The stainless steel dust cover 03 is shaped into an inverted U shape from a metal plate and penetrates through the U-shaped through groove 15. Two ends of the stainless steel dust cover 03 are sealed by the L-shaped dust-proof plates 11. An upper portion of each L-shaped dust-proof plate 11 is fixed on a lower side of the stainless steel dust cover 03 by means of a bolt, and a lower portion of the L-shaped dust-proof plate 11 is fixed on an end face of the machine tool bridge by means of a bolt. Each organ-type dust cover 04 is disposed under the stainless steel dust cover 03 and has one end connected to the worktable base 06 and the other end connected to the corresponding L-shaped dust-proof plate 11, and two organ-type dust covers 04 are distributed on two sides of the worktable base. The worktable 01 covers the stainless steel dust cover 03 and is connected to the worktable base 06 by means of bolts. U-shaped dust-proof grooves 05 are formed between two sides of the machine tool bridge 07 and the organ-type dust covers 04 to seal slots in the lower ends of the organ-type dust covers, thereby improving the leakproofness of the machine tool. The dust-proof brushes 12 are arranged on the left and right end faces (relative to FIG. 2) of the worktable 01, respectively.

[0020] The dust-proof device for the machine tool worktable provided by the present invention works by following the following principle: the servomotor 08 drives, by means of the coupling 09, the pair of lead screws 10 to rotate to pull the worktable base 06 and the worktable 01 to move leftwards and rightwards as guided by the pair of linear guide rails 02; the dust-proof brushes 12 at the two ends of the worktable 01 then remove iron scrap, waste residue, wastewater and the like produced in workpiece machining, which may be discharged into a waste tank below the machine tool. By means of multiple protective parts such as the stainless steel dust cover 03, the organ-type dust covers 04, the U-shaped dust-proof grooves 05, the L-shaped dust-proof plates 11, the dust-proof brushes 12, the leakproofness of the machine tool is improved, and steady and efficient operation of the machine tool can be guaranteed.
