Abstract

The invention provides a bladed disc machining center. The bladed disc machining center comprises an A-axis rotary assembly, a B-axis rotary assembly and a C-axis rotary assembly, wherein the A-axis rotary assembly drives a blade disc to do rotary motion; the B-axis rotary assembly drives an accessory head to do rotary motion, and the accessory head drives a tool to machine the bladed disc; the C-axis rotary assembly drives the A-axis rotary assembly to do rotary motion; the intersection point of the rotating axis of the B-axis rotary assembly and the rotating axis of the C-axis rotary assembly is the center of the machining area of the bladed disc; and the tool nose point of the tool is on the rotating axis of the B-axis rotary assembly. According to the bladed disc machining center, themachining area is close to the rotating center of a C-axis rotary table, and it can be guaranteed that when a machine tool conducts five-axis rotating tool center machining action, the movement speedand acceleration of all physical axes can be kept within a low range compared with those of a machine tool of a common structure.

Description

technical field [0001] The invention relates to the field of machine tool processing, in particular to a blisk processing center. Background technique [0002] The use of blisks in aero-engines is the development trend of aero-engine technology in the world. In order to expand the application of blisks in aero-engines, the manufacturing problems of blisks must first be solved. At present, the number of blisks used in my country's aero-engines is small, and the main reason why they cannot be widely used is that the manufacturing technology of blisks has not yet been solved. The difficulty in manufacturing the blisk of an aero-engine lies in the complex profile of the blade, high processing accuracy and surface quality requirements, extremely high blade processing consistency, blade processing deformation, and the materials used. The blade surface of the overall blisk is mostly a free-form surface, and there are extremely high requirements on the machining accuracy and surfac...
