Description

Technical Field

[0001] The utility model relates to the field of numerical control machine tools, in particular to a protective cover for numerical control machine tools. Background Art

[0002] CNC machine tools are digitally controlled machine tools, which are automated machine tools equipped with a program control system. The control system can logically process programs specified by control codes or other symbolic instructions, decode them, and express 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. The protective cover is a protective device during CNC machine tool processing to prevent iron chips from flying out during processing and reduce injuries to operators. The protective cover of a CNC machine tool generally observes the working condition of the control machine tool in operation through an observation window. However, the observation window during operation may be blocked by dust generated during processing and affect the line of sight. The existing protective cover of a CNC machine tool lacks a structure for cleaning the dust from the observation window during operation. When the observation window is dirty, the protective cover of the CNC machine tool needs to be disassembled and the observation window cleaned. The observation window cannot be cleaned directly from the outside of the protective cover of the CNC machine tool during operation, which takes a lot of time and has low work efficiency. In addition, the connecting mechanism of the existing protective cover of a CNC machine tool cannot be adjusted, and the connecting part of the CNC machine tool of a single thickness can only be clamped and fixed to complete the installation.
