Pose adjusting ball device for airplane assembly

Abstract

The invention discloses a pose adjusting ball device for airplane assembly and belongs to the field of airplane manufacturing equipment. The defects that errors are large and the stress of the connecting portion is large exist in the airplane body pose adjustment process due to the adoption of a special fixture or a jack manual operation manner currently. The pose adjusting ball device comprises a ball socket seat and an installation seat used for being connected with and supporting an airplane body. A connecting flange is arranged at the upper portion of the installation seat and the lower portion of the installation seat is fixedly connected with a ball through a connecting rod. An installation seat installation cavity is formed in the center of the ball socket seat. A ball socket corresponding to the ball is arranged at the lower portion of the installation cavity. The installation seat is installed in the ball socket seat. Three clamping devices are evenly arranged on the sides of the ball socket seat in the circumferential direction. An in-position detection switch is arranged at the bottom of the ball socket seat. The pose adjusting ball device is combined with a three-coordinate numerical control locator, accuracy errors existing in manual pose adjustment are effectively avoided, airplane assembly automation and intelligence are improved, and the pose of the airplane body can be better adjusted in six directions.

Description

technical field [0001] The invention belongs to the field of aircraft manufacturing equipment, and in particular relates to an attitude-adjusting ball head device for aircraft assembly. Background technique [0002] In aircraft assembly, in order to ensure the interchangeability and coordination of aircraft fuselage butt joints, finishing operations are required to eliminate accumulated errors after the fuselage components are assembled. The pose adjustment before fuselage finishing should meet the requirements of wing-body fit accuracy and fuselage relative position accuracy, that is, the intersection holes of wing-body meet the machinability evaluation, and make the height difference of fuselage measurement points meet the technical requirements. [0003] In the traditional aircraft assembly and positioning, the aircraft and its components are often fixed on a special frame through shape clamps and pins, or multiple jacks are used to jack up the aircraft components, and th...

Problems solved by technology

[0004] The purpose of the present invention is to overcome the disadvantages of low equipment utilization rate, large attitude adjustment error and inconvenient operation in the current way of adjusting the attitude of the fuselage through a special frame or manual operation jack, and provide a reusable, and can cooperate with three-coordinate numerical control. The positioner allows the fuselage to freely adjust the attitude of the body at 6 angles in space. The ball head mechanism of the attitude adjustment positioner
