Description

Technical Field

[0002] CNC machine tools are machine tools that integrate digital control systems into ordinary milling machines and can perform milling processing more accurately under the control of program codes. CNC machine tools are divided into two categories: those without tool magazines and those with tool magazines. CNC machine tools with tool magazines are also called machining centers. The basic parts of CNC machine tools usually refer to structural parts such as bed, columns, beams, worktables, and bases. They are large in size (commonly known as large parts) and constitute the basic framework of the machine tool.

[0003] After the CNC machine tool is completed, iron filings and coolant will remain in the grooves of its working platform. Most of the existing technologies clean them manually, which increases the labor intensity and is inefficient. In addition, there are also methods that use a moving mechanism to drive a brush to reciprocate to clean its working platform. However, during the cleaning process, iron filings will adhere to the brush and fall off the brush during the reciprocating motion of the brush, resulting in poor cleaning effect. Further development and improvement are needed. Utility Model Content

Then the drive motor and the moving mechanism are controlled to start working, so that the adsorption roller makes a horizontal reciprocating motion while rotating, and all the iron filings on the workbench surface are adsorbed and cleaned. After the iron filings on the workbench are cleaned, the adsorption roller is driven by the moving mechanism to move to the top of the rectangular hollow discharge slot at one end of the workbench, and the electromagnet is controlled to stop working and the drive motor is controlled to continue to drive The adsorption roller rotates, so that the iron filings adsorbed on the circumferential surface of the adsorption roller fall into the collection box through the rectangular hollow discharge trough.
