Description

Technical Field

[0001] The utility model relates to the field of protection of machine tools, and particularly relates to a protection device for a machine tool guide rail. Background Art

[0002] Parts that support and guide moving components to move along a certain trajectory are called guide rail pairs, often simply referred to as guide rails. The movement trajectories of moving parts are straight lines, circles or curves. Rolling circular guide rails can be classified into rolling thrust bearings. Curved guide rails are rarely used in machinery. Guide rails are very important components in machines, especially in machine tools. The machining accuracy of machine tools is directly related to the accuracy of guide rails. In precision machine tools for small-batch production, the machining workload of guide rails accounts for about 40% of the total machining workload of the entire machine tool. Moreover, once the guide rails are damaged, it is very difficult to repair.

[0003] The guide rail is the main accessory for the displacement of the machine tool and directly affects the axial movement accuracy of the machine tool. The existing machine tool guide rails lack good protection devices, resulting in sewage and waste chips generated during processing may contact the guide rails, thus affecting their service life and stability.

[0004] Therefore, it is very necessary to propose a protection device for a machine tool guide rail to solve the above problems. Content of the Utility Model
