Description

Technical Field

[0001] The utility model relates to a novel machine tool safety protection device, belonging to the field of machine tools. Background Art

[0002] The sliding door of a machine tool is a common protective device for machine tools. It is used to protect the safety of operators, prevent splashing of cutting fluids and chips, and help maintain a clean working environment. To facilitate the movement of the sliding door, multiple guide wheels are installed on the sliding door, and guide rails are installed on the machine tool shell. The guide wheels and the guide rails are in rolling contact. When the sliding door is moved, the sliding door drives the guide wheels along the guide rails. Currently, the guide rails are fixed to the machine tool shell, so that the contact point between the guide rails and the guide wheels remains unchanged. After long-term use, the contact point between the guide rails and the guide wheels will wear. On the one hand, this makes the sliding door move unsmoothly, and on the other hand, the guide rails need to be replaced frequently. Therefore, it is necessary to design a new machine tool safety protection device that reduces the frequency of guide rail replacement. Utility Model Content
