Five-axle linked blade processing center

Abstract

The invention discloses a center for processing a five-shaft linkage blade, which comprises a lathe bed, a rotary table installed on the lathe bed, a trailing bar which can move along the lathe bed, a column which can move along the trailing bar, a swinging mechanism and a main shaft case, wherein, the swinging mechanism comprises a swinging shaft and a swing shaft drive mechanism; the swinging shaft is installed on the column and the swinging shaft drive mechanism is positioned in the column; an arc-shaped railway is arranged on the column by which the swinging shaft can swing; a feed mechanism for moving the main shaft case is arranged in the swinging shaft; the main shaft case is installed on the swinging shaft and can move along the swinging shaft. Due to the mechanical transmission structure, the errors caused by the drifting of mechanical structure self are reduced, thus the transmission of the system and the operation of a cutting-tool and a workpiece are more reasonable and harmonious; the distance between the cutting tool and the processing surface is shortened to a fullest extend; and the errors are reduced; in addition, the control of the problems such as tool compensation amount and the programming of the entire structure are more direct and compact, thus enhancing work efficiency and finally enhancing the precision for processing the workpiece.

Description

technical field [0001] The invention relates to a numerical control machine tool, in particular to a five-axis linkage blade machining center. Background technique [0002] Multi-axis linkage CNC machining is the most difficult but most widely used technology in CNC technology. It is mainly used for efficient, precise and automatic processing of complex curved surfaces. It is the key processing equipment for important civil and military industries such as power generation, ships, and aerospace. Internationally, multi-axis linkage CNC machining technology is used as a symbol of a country's industrialization level. The five-axis linkage machining center is a CNC machine tool composed of linear coordinate axes (X, Y, Z) and two rotary coordinate axes (A, B) to realize five-axis linkage interpolation machining. Among them, the five-axis linkage blade machining center is specially used to process various blades of steam turbines and aircraft engines and other narrow and long par...

Problems solved by technology

[0003] The main structure of the existing five-axis linkage blade machining center includes a bed, a carriage for X-axis movement, a column for Y-axis movement, a turntable for A-axis movement, a Z-axis slide plate, and a headstock for B-axis movement. The box is installed on the Z-axis slide plate, but this five-axis linkage machining center has the following defects: First, because the tool is far away from the rotary center, the programming is quite complicated and lengthy, and the control accuracy of the tool compensation is also poor; The second is that the relative positional relationship between the tool and the workpiece is offset, resulting in a large error, and the precision of the processed blades cannot meet the existing needs.
