A multi-parallel co-integration processing equipment and processing method for large curved surface parts

Abstract

A multi-parallel tri-co processing apparatus for parts having a large-curved surface, comprising: a parallel loading device (2), a serial-parallel robotic device (4), an integrated polishing device, and a tri-co control and detection system; the parallel loading device (2) comprises a support seat (2-1), a UPU drive chain (2-2), a constrain support chain (2-4), and a rotating platform (2-3); the serial-parallel robotic device (4) comprises a support frame (4-1), a UPS drive chain (4-2), a UP constrain secondary chain (4-5), a moving platform (4-3), and a two-degree-of-freedom rotator (4-4). During operation, a blank (3) is clamped on the rotating platform (2-3), and the integrated polishing device is assembled at the terminus of the two-degree-of-freedom rotator (4-4). The tri-co control and detection system enables the parallel loading device (2) and the serial-parallel robotic device (4) to cooperate with one another, achieves active compensation for processing errors, and interaction and tri-co with human and the external environment, and allows for integrated intelligent processing from blank model building to milling and polishing for parts having a large-curved surface and parts having a complex surface. The system is also stable in structure and high in precision and rigidity, and enables tri-co among multiple devices. Also disclosed is a processing method for the multi-parallel tri-co processing apparatus for parts having a large-curved surface.

Description

technical field [0001] The invention relates to a large curved surface part processing equipment and a processing method, in particular to a multi-parallel co-integration large curved surface part processing equipment and a processing method, belonging to the technical field of precision and intelligent processing equipment. Background technique [0002] In order to meet the needs of economic and social development and national defense construction for major technical equipment, my country has formulated a development route that takes the deep integration of the new generation of information technology and manufacturing as the main line, and promotes intelligent manufacturing as the main direction. In the field of high-precision and intelligent processing, the common processing methods of traditional CNC machine tools or tandem robotic arms have the problems of low processing accuracy, heavy processing and assembly, and poor processing flexibility, which are increasingly unab...

Problems solved by technology

[0003] However, compared with the series robot, the single parallel robot is greatly limited in the working stroke and working angle due to the limitation of its own mechanism, and its defects are especially obvious when processing large curved surface parts or complex curved surface parts.
