Aggregate machinery for machining large-sized mechanical components

Abstract

The invention discloses a combined machine tool for processing large mechanical parts, which comprises a numerical control system, a main worktable, a vertical lathe worktable, a portal frame, a vertical boring and milling head component, a left horizontal boring and milling head and a right horizontal boring and milling head, wherein the vertical lathe worktable is arranged in a center hole of the main worktable; in the portal frame, upper ends of a gantry right upright post and a gantry left upright post are fixedly or movably connected with a gantry beam, and lower ends of the two upright posts are in assembly connection with guide rail platforms at two sides of the main worktable through an upper right guide rail and an upper right guide rail groove, a lower right guide rail and a lower right guide rail groove, an upper left guide rail and an upper left guide rail groove, a lower left guide rail and a lower left guide rail groove; the vertical boring and milling head component comprises a vertical boring and milling head bracket and a vertical boring and milling head, and is in assembly connection with the gantry beam through a linear guide rail and a linear guide rail groove; right and left horizontal boring and milling head outer shells of the right and left horizontal boring and milling heads pass through rectangular through holes in the middle of the two upright posts from two sides of the portal frame respectively and pass through right and left horizontal boring and milling head brackets to form sliding connection; and the right and left horizontal boring and milling heads can be lifted vertically and moved transversely.

Description

technical field [0001] The invention relates to a processing equipment for mechanical parts, more specifically, it relates to a combined machine tool for processing large mechanical parts. Background technique [0002] The parts required for large-scale equipment, such as the main parts such as the wheel hub, the front nacelle chassis, and the bearing housing used in the wind turbine, are all complex in structure, with many spatial processing surfaces, and high requirements for shape and position tolerances and machining accuracy. The machine tools required for processing are turning, planing, boring, milling, drilling and other equipment. Therefore, each process must use an independent processing machine tool, and the various processes are switched, and the processing machine tool is frequently replaced. At present, the general processing equipment involved in the domestic processing of large-scale mechanical parts and components includes boring, milling, planing, turning, ...

Problems solved by technology

[0002] The parts required for large-scale equipment, such as the main parts such as the wheel hub, the front nacelle chassis, and the bearing housing used in the wind turbine, are all complex in structure, with many spatial processing surfaces, and high requirements for shape and position tolerances and machining accuracy. The machine tools required for processing are equipment such as turning, planing, boring, milling, drilling, etc. Therefore, each process must use an independent processing machine tool, and the various processes are connected and frequently replaced.

At present, the general processing equipment involved in the domestic processing of large-scale mechanical parts and components includes boring, milling, planing, turning, drilling, and thread processing machine tools. , Repeated loading of the card, which will inevitably lead to problems such as large investment in equipment, large floor space, many auxiliary man-hours, and large cumulative error in machining accuracy.
