Description

Technical Field

[0001] The present application relates to the technical field of machine tool cleaning, and in particular to a cleaning device for a numerically controlled machine tool. Background Art

[0002] A CNC machine tool is an automated machine tool equipped with a program control system that can logically process programs specified by control codes or other symbolic instructions, decode them, and represent them in coded numbers, which are input into the CNC device through information carriers. After calculation and processing, the CNC device sends various control signals to control the movement of the machine tool, and automatically processes parts according to the shape and size required by the drawing. CNC machine tools need to be cleaned regularly to ensure the normal service life of the machine tool.

[0003] The patent document with publication number CN219310796U in the prior art provides a cleaning mechanism for a CNC machine tool. The device installs a cleaning member on a workbench so that its scraping portion contacts the upper surface of the workbench. When the machine tool is working, the cleaning member slides back and forth on the workbench through the cooperation of a driving member, and scrapes the debris on the upper surface of the workbench, so that the debris is scraped into a receiving box by the scraping portion, thereby reducing the presence of debris on the upper surface of the workbench and reducing the influence of the debris on the accuracy of the machine tool.

[0004] Although the above-mentioned prior art solution can scrape the debris on the surface of the workbench by contacting the scraping part with the upper surface of the workbench, it still has the following defects: the prior art cleans the debris on the surface of the workbench, but does not have the ability to clean parts such as cutting tool fixtures. If the cutting tool is stained with cutting debris, it will affect the next use and seriously damage the cutting tool.

[0005] In view of this, we propose a cleaning device for CNC machine tools. Utility Model Content
