Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of lubrication devices, in particular to a lubrication device for a large-torsion gantry machining center. Background Art
[0002] A gantry machining center is a large CNC machine tool, typically used to process large workpieces. Its structural features include a fixed gantry that spans the workpiece, and a movable worktable or spindle, which enables cutting operations in multiple directions. It is particularly suitable for processing large workpieces and workpieces with complex shapes. It is widely used for high-precision processing in industries such as aviation, automobiles, and molds. Compared with ordinary gantry machining centers, high-torque gantry machining centers have stronger torque output capabilities, which means that high-torque gantry machining centers can provide greater cutting force during the machining process, thereby processing harder materials and more complex workpieces.
[0003] At present, the existing lubrication devices for gantry machining centers are mostly used to supply lubricants to some components that are frequently subjected to friction during use. However, for high-torque gantry machining centers, because they need to handle larger loads and generate larger torques, all key components of the high-torque gantry machining centers need to be effectively lubricated. Otherwise, it will lead to increased wear between components and cause uneven movement between mechanical components, thereby affecting machining accuracy. Under high-torque operation, the uneven movement between machine components will directly affect the quality of the final workpiece. Utility Model Content
