Semi-automatic electromagnetic riveting system for conical shell class structural part

Abstract

The invention discloses a semi-automatic electromagnetic riveting system for a conical shell class structural part. The semi-automatic electromagnetic riveting system comprises a fixture linkage assembly, a riveter assembly and an ejection handle assembly. The fixture linkage assembly provides support for all components of the riveting system. The riveter assembly and the ejection handle assembly form a dual-damping structure through buffers and ejection air cylinders, and meanwhile riveting damping is conducted, so that the harmful effects of recoil force on operators are eliminated. The ejection air cylinders are used for providing ejection force for an electromagnetic riveter and an ejection handle, and the constant single riveting ejection force is ensured by keeping the pressure value of the ejection air cylinders constant, so that the riveting quality uniformity is improved. In the riveting process, the movement synchronization of the electromagnetic riveter and the ejection handle in the direction of stand columns and guide rails is ensured through the fixture linkage assembly, and one-man operation of the riveting process is achieved. The pitch angles of the electromagnetic riveter and the ejection handle are adjusted through corresponding rotation devices, and the positioning precision is high, so that the conical-face normal positioning of conical-shell workpieces in the riveting process is achieved and the riveting quality of the conical-shell workpieces is improved.

Description

technical field [0001] The invention belongs to the technical field of process equipment structure design and manufacture, and in particular relates to a semi-automatic electromagnetic riveting system for conical shell-like structural parts. Background technique [0002] Electromagnetic riveting is a new process method, which has been applied in the field of aerospace vehicle manufacturing and processing. Electromagnetic riveting is generally divided into two methods: manual riveting and automatic riveting. Manual riveting equipment is simple, flexible and convenient to operate, and low in economic cost. It is currently the most widely used riveting method in the domestic aerospace manufacturing field. The disadvantages are poor riveting quality consistency and high labor intensity; The axis is perpendicular to the surface of the workpiece, and it is easy to damage the workpiece during riveting. Automated riveting has the advantages of high riveting quality consistency and...
