Description

Technical Field

[0001] The utility model relates to the technical field of machine tool guide rails, in particular to a machine tool sliding guide rail mechanism. Background Art

[0002] The parts that support and guide moving components along a specific trajectory are called guide rails, often referred to as guide rails. The trajectory of moving components can be straight, circular, or curved. Rolling circular guides can be classified as rolling thrust bearings, while curved guides are rarely used in machinery. Guide rails are a very important component in machines, especially in machine tools. The machining accuracy of machine tools is directly related to the accuracy of the guide rails. For precision machine tools produced in small batches, the machining workload of guide rails accounts for approximately 40% of the total machining workload. Moreover, once a guide rail is damaged, it is very difficult to repair. Due to the poor air conditions in the machine tool processing environment, the surface of the guide rail is easily contaminated by dirt. Over time, this can cause friction on the guide rail surface, reducing the smoothness of the guide rail and, in severe cases, causing damage to the guide rail. To this end, we have proposed a sliding guide rail mechanism for machine tools. Utility Model Content
