Description

Technical Field

[0001] The utility model belongs to the technical field of machine tool protection, and specifically relates to a machine tool protection cover for a bridge-type gantry five-axis boring and milling compound machining center. Background Art

[0002] The bridge gantry is a gantry machine tool with a bridge-type crossbeam and long side walls. The bridge gantry machine tool is equipped with a replaceable spindle head and a replaceable spindle tool. The chips are mainly in powder form. During high-speed processing, the coolant will produce oil mist, so complete protection is required; the size of this bridge gantry workbench is 3m×6m, and the processing height is 3m. The processed parts are large in size and require a crane for clamping, so it is necessary to have a device that facilitates the entry and exit of the workpiece.

[0003] In addition, the protective devices of traditional bridge-type gantry machine tools are generally simple. Because of the side walls, they only protect the front and back, and there is no protection on the top and inside and outside of the side walls, or only the bed is protected, and no protection is provided around. During the processing, coolant and lubricating oil will splash with the chips, and the chips and oil will directly contact the side walls, which will cause bumps and corrosion over time. At the same time, there are no effective treatment measures for processing dust and oil mist, which will cause air pollution in the factory, resulting in a high equipment failure rate.
