Description

Technical Field

[0001] This utility model relates to the technical field of fixed beam gantry machining centers, specifically a crossbeam support structure for a fixed beam gantry machining center. Background Technology

[0002] A gantry machining center is a machining center whose spindle axis is perpendicular to the worktable. The overall structure is a large machining center with a portal frame structure consisting of double columns and a top beam. There is also a crossbeam in the middle of the double columns. It is especially suitable for machining large and complex-shaped workpieces. The fixed beam type is a machining method in which the crossbeam does not move during machining, while the worktable moves. The crossbeam support structure of the fixed beam gantry machining center is the column used to support the measurement. Generally, two sets are used together. The crossbeam support structure of the fixed beam gantry machining center usually has a lifting function. This function is realized by the hydraulic telescopic cylinder installed inside. However, after the crossbeam is raised, the hydraulic telescopic cylinder needs to bear the weight from the crossbeam and the equipment installed on the crossbeam. Utility Model Content
