Description

Technical Field

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

[0002] CNC machine tools are automated machine tools that are controlled by digital programs and can accurately perform various processing operations according to preset programs. The core parts of CNC machine tools include the CNC system, servo drive system and host structure. Among them, the CNC system is responsible for interpreting and executing program instructions, the servo drive system controls the movement of the machine tool, and the host structure is the physical frame that carries and supports the entire processing process. In order to ensure the safety of the machine tool during processing, a protective cover will be installed on the outside of the bed to prevent debris from flying out during processing.

[0003] Common CNC machine tool protective covers are generally composed of a door-like structure, which is inserted into the front of the shell through a slot and can be pushed and pulled left and right to achieve protection when in use. However, in this method, since the protective cover is clamped inside the shell, and in order to ensure the stability of the protective cover during the pushing and pulling process, the protective cover and the guide rail are clamped tightly when installed. Therefore, when disassembling and assembling, it is necessary to first remove the clamping guide rail and then remove the shell before the protective cover can be removed. The whole process is time-consuming and labor-intensive and cannot meet the working requirements of the machine tool protective cover. For this reason, a protective cover for CNC machine tools that is easy to disassemble is proposed. Utility Model Content
