Ball head in-place device and large component butt joint posture adjusting system

Abstract

The invention discloses a ball head in-place device and a large component butt joint posture adjusting system.The ball head in-place device comprises a ball socket seat and a clamping mechanism, the clamping mechanism comprises a clamping pin and a driving piece, a through hole is formed in the ball socket seat, the through hole is communicated with a ball socket of the ball socket seat, the clamping pin penetrates through the through hole and is partially inserted into the ball socket seat, an in-place groove is formed in the clamping pin, the clamping pin is provided with an in-position station with an in-position groove opposite to the ball socket and an anti-escape station with the in-position groove staggered with the ball socket, the driving part is arranged on the ball socket seat, the driving part is connected with the clamping pin, and the driving part can provide driving force for the clamping pin, so that the clamping pin can be switched between the in-position station and the anti-escape station. The ball head in-place device has the advantages of simple structure, low cost and convenience in use, and the high-precision, high-efficiency and low-cost assembly of large components of an airplane can be realized. Correspondingly, the invention further provides the large component butt joint posture adjusting system.

Description

technical field [0001] The invention relates to the field of aircraft manufacturing, in particular to a ball head positioning device and a large component docking attitude adjustment system. Background technique [0002] With the rapid development of the domestic aviation industry, CNC positioners are widely used in the docking and attitude adjustment of large aircraft components. The ball joint positioning device is a digital equipment process joint, which is the connecting point connecting the aircraft product and the numerical control positioner. The ball joint positioning device is used in conjunction with the numerical control positioner to reliably complete posture adjustment and docking. Generally, the ball head positioning device has three states: loosening, escape prevention and locking. The traditional ball head positioning device generally adopts a bolt type anti escape structure or a ball head circumferential claw type anti escape structure. However, the use of ...

AI Technical Summary

Problems solved by technology

However, the use of the pin-type anti-escape structure of the ball joint positioning device often occurs when the pin cannot be inserted, which affects the efficiency and accuracy of docking and attitude adjustment, which in turn affects the assembly accuracy and assembly efficiency of large parts of the aircraft; while the use of ball joints The spherical head positioning device of the circumferential catch type anti-escape structure has a complex structure and a large volume, which makes the use cost high and inconvenient to use, which affects the assembly cost and assembly efficiency of large aircraft components to a certain extent
