Description

[0001] The utility model relates to the technical field of numerical control edge milling machines, in particular to a spindle structure of a numerical control edge milling machine. Background Art

[0002] Edge milling machines are welding auxiliary equipment that utilize the high-speed milling principle of a cutter head. They are specifically designed to create weld grooves for steel plates before welding. They are primarily categorized into several types, including automatic travel edge milling machines, large-scale edge milling machines, and CNC edge milling machines. They are widely used in boiler and pressure vessel manufacturing, shipbuilding, electric power, petroleum, chemical machinery, and engineering machinery manufacturing. They can produce beveled edges, straight edges, and U-shaped grooves on various low- and medium-carbon steel plates, stainless steel plates, and aluminum plates before welding. The spindle of an edge milling machine is typically connected to the milling shaft via a coupling. However, as the machine rotates and mills, waste chips are generated that fly around, cluttering the processing surface and making waste cleaning inconvenient. To address this issue, we have proposed a spindle structure for a CNC edge milling machine. Utility Model Content
