Five-axis linkage CNC drilling and riveting equipment with ab rotary motion axis double drive mechanism

Abstract

The invention discloses five-axis linkage numerical control drill-riveting equipment with an AB rotational motion axis double driving mechanism. A dual rotational motion axis single driving mechanism comprises an A-axis revolving seat, a first servo motor, a second servo motor, a first A-axis small gear, a second A-axis small gear, a first A-axis large gear, a second A-axis large gear, a B-axis large gear, a third servo motor, a fourth servo motor, a first B-axis driving end rotary bearing assembly and a second B-axis driving end rotary bearing assembly. The two sides of the A-axis rotary seat are in running fit around an axis A relative to a three-axis motion assembly, and a hole sprigging head is movably mounted in the A-axis rotary seat and rotates around an axis B. The first servo motor and the second servo motor are mounted on the three-axis motion assembly. The first A-axis small gear is in running fit with the first servo motor, and the second A-axis small gear is in running fit with the second servo motor. The first A-axis large gear and the second A-axis large gear are fixed to the two sides of the A-axis rotary seat, the first A-axis large gear is in meshing transmission with the first A-axis small gear, and the second A-axis large gear is in meshing transmission with the second A-axis small gear. The B-axis large gear is fixedly connected with the manufactured hole sprigging head. The third servo motor and the fourth servo motor are mounted on the A-axis rotary seat. The first B-axis driving end rotary bearing assembly and the second B-axis driving end rotary bearing assembly carry out driving to be in meshing transmission with the B-axis large gear.

Description

technical field [0001] The invention relates to the field of aircraft assembly technology and equipment, in particular to a five-axis linkage numerical control drilling and riveting equipment with AB rotary motion shaft double drive mechanism. Background technique [0002] Riveting technology is a mechanical connection technology commonly used in the aviation manufacturing industry. Its processing technology is relatively simple, the riveting quality is easy to control, and it has the advantages of light weight and high strength. It has been widely used in the field of aviation manufacturing. The quality of traditional riveting products is greatly affected by individual factors of workers, so it is difficult to ensure stable, high-quality and efficient connections. In order to ensure the assembly quality of aircraft and improve the efficiency of aircraft assembly, it is an inevitable trend to develop automatic drilling and riveting technology and use automatic drilling and r...

AI Technical Summary

Problems solved by technology

Most of the driving components of the AB rotary motion axis of the traditional five-axis linkage CNC machine tool are purchased modules, which have a small load capacity and cannot meet the requirements of high load capacity and high machining accuracy of the five-axis linkage CNC drilling and riveting equipment.
