Problems solved by technology

[0002] In the process of aircraft manufacturing, engine installation is an important link. Engines vary in size from several hundred kilograms to several tons, and the installation methods of engines are roughly divided into two types: upper lifting and lower lifting. There are two types of inner crane installation, the degree of freedom of the hoisting space is completely released, the operation is simple, and the operation time is short, but limited by the degree of freedom is too free, if the crane operation step is too large, it is easy to cause product collision; the lower lifting installation is mainly as follows The lower fulcrum is mainly used for lifting to install the engine. Compared with lifting, the lower lifting takes more time to prepare and the equipment is more complicated, but the lifting precision control is more precise and the installation is safer

Abstract

The platform discloses a six-degree-of-freedom installation platform. The platform is composed of a chassis, Z-direction columns, an adapter frame, a posture adjusting frame and the like; the chassisis of a plane frame structure, and the Z-direction columns are provided with lifting support structures capable of screw rod transmission; the Z-direction columns are fixed at the four corners of thechassis, supporting ball heads of the four corners of the adapter frame respectively form ball hinge structures with the supporting structures on the four Z-direction columns, and the adapter frame isfixed above the posture adjusting frame through a sliding seat; during the installation process, the adapter frame is moved up and down and conducts flip-flop movement along the Z-direction columns,and the posture adjusting frame conducts translation and rotation movements along the upper surface of the adapter frame in an XY plane.

Description

technical field [0001] This application relates to the assembly technology of large parts of aircraft, especially a six-degree-of-freedom installation platform used for the lower lift installation of the engine. Background technique [0002] In the process of aircraft manufacturing, engine installation is an important link. Engines vary in size from several hundred kilograms to several tons, and the installation methods of engines are roughly divided into two types: upper lifting and lower lifting. There are two types of inner crane installation, the degree of freedom of the hoisting space is completely released, the operation is simple, and the operation time is short, but limited by the degree of freedom is too free, if the crane operation step is too large, it is easy to cause product collision; the lower lifting installation is mainly as follows The lower fulcrum is mainly lifted to install the engine. Compared with the hoisting, the lower lifting takes more time to prep...
