Problems solved by technology

[0005] Due to the limited working space of existing processing equipment, it is difficult to achieve high rigidity and large extension, so it is impossible to complete the processing of the spherical crown surface of large storage tanks. At present, the processing of spherical crown surfaces of large storage tanks is mainly carried out manually. Long, low production efficiency, and poor precision, can not guarantee the technical requirements of processing, the application provides a foldable parallel mechanism and its application

Abstract

This application belongs to the field of aerospace technology, especially a foldable parallel organization and its application.Existing processing equipment not only has long cycle, low production efficiency, but also poor accuracy, and cannot guarantee the technical requirements of processing.This application provides a foldable parallel -connected mechanism, including the base, the base of the base and the cut -type stretch branches, the other end of the cut -type stretch branch chain connects to the dynamic platform.Component connection; cut -type stretching branches include branches driver components, branched chain drive components connect to one end of the main connector, connect to one end of the main support rod, connect to the other end of the main support rod, and the support chain chain chain chain chain chain chain chainDrive components connect to the base. The other end of the main connection rod is connected with one end of the cut branch structure, one end of the cut branch branch structure is connected to the main support rod, and the other end of the cut branch branch structure is connected to the platform.Can meet different stiffness needs.

Description

technical field [0001] The present application belongs to the field of aerospace technology, and in particular relates to a foldable parallel mechanism and its application. Background technique [0002] The processing of complex spherical caps of large tanks in the aerospace field requires a large extension space for processing equipment due to the large structural size of the tank and the horizontal layout of the overall processing. When the workpiece is placed horizontally, the spherical cap of the workpiece is oversized, and the processing direction is along the axis of the workpiece, so the processing equipment needs to have a large extension distance along the axis of the workpiece, and at the same time, it can meet the rigidity requirements and avoid stretching too long. lead to structural deformation. The traditional five-axis CNC machine tool can process complex curved parts, but due to the huge size of the workpiece in the tank, it cannot reach the processing range...
