Iron jacking mechanism for electromagnetic riveting of robot drilling and riveting work station

Abstract

The ejector iron mechanism for electromagnetic riveting of the robot drilling and riveting work station comprises a guide block, ejector iron is installed in the guide block in a sliding mode, an ejector iron head and a riveting head are detachably installed on the two sides of the ejector iron respectively, and a limiting mechanism and a reset mechanism are arranged between the guide block and the ejector iron. A sliding cavity is formed in the guide block, and the jacking iron slides in the sliding cavity; the limiting mechanism comprises a rear-position buffer block and a front-position buffer block, a limiting cavity is formed in the middle of the jacking iron and communicates with the sliding cavity, and the rear-position buffer block and the front-position buffer block are fixedly installed in the limiting cavity; the reset mechanism comprises a spring, the bottom end of the spring abuts against the guide block, and the other end abuts against the ejector iron. The device is simple in structure and small in occupied space; riveting can be conducted in the area where a straight-rod riveter head cannot reach, and rivets in the area shielded by a partition plate of a skin and reinforcing ribs are upset.

Description

technical field [0001] The invention belongs to the technical field of drilling and riveting tools, and relates to a top iron mechanism for electromagnetic riveting of a drilling and riveting workstation. Background technique [0002] With the continuous development of the domestic aviation industry, the demand for the number of aircraft is also increasing, and the requirements for the level of aircraft manufacturing are also getting higher and higher. This puts forward higher requirements on the quality and efficiency of aircraft skin drilling and riveting, and puts forward higher requirements on the processing capacity and automation level of processing equipment. As an efficient and high-quality riveting method, electromagnetic riveting has been gradually put into use. The general manual riveting method is labor-intensive and time-consuming, and the labor intensity is high, and the influence of human factors on the quality of riveting is very obvious.
