Automatic drilling and riveting actuating mechanism and method suitable for rocket cabin riveting

Abstract

The invention provides an automatic drilling and riveting actuating mechanism and method suitable for rocket cabin riveting. The automatic drilling and riveting actuating mechanism comprises a rivet shooting module, a rivet inserting and riveting module, a drilling and counterboring module, a switching module, and a compression and distance measurement module, wherein the compression and distancemeasurement module is used for compressing a rocket cabin; the drilling and counterboring module is used for completing drilling or counterboring on the surface of the cabin, and meanwhile the rivet shooting module is used for injecting a rivet into the tail end of the rivet inserting and riveting module; the switching module is used for realizing the position exchange of the drilling and counterboring module and the rivet inserting and riveting module; and the rivet inserting and riveting module is used for inserting the rivet into a prepared hole position and completing riveting. The automatic drilling and riveting actuating mechanism can realize the automatic feeding and inserting process of various types of rivets, detects each process to avoid the situation of no rivets and crooked rivets, and effectively protects the rocket cabin; and the compression and distance measurement module is used for measuring the position of the cabin and feeding back and correcting the feed amount ofhole preparation and counterboring so as to adapt to the roundness error of the cabin. The automatic drilling and riveting actuating mechanism replaces the manual drilling and riveting operation, greatly reduces the labor intensity and can significantly improve the efficiency.

Description

technical field [0001] The invention relates to a device for automatic assembly, in particular to an automatic drilling and riveting actuator and method suitable for riveting rocket cabins. Background technique [0002] Riveting is an important process in the manufacturing process of the rocket cabin. In the past, the end frames, shell segments, skins, stringers and other parts to be riveted were pre-assembled on the jig, and the holes were manually made and countersinked, and then After manual nail insertion, the final manual riveting. Since there are tens of thousands of rivets on the rocket cabin, there is serious noise in the drilling and riveting process, which makes manual riveting labor-intensive, easy to cause harm to the body, and low production efficiency. Based on the urgent demand for automatic drilling and riveting technology, aerospace manufacturing enterprises have gradually begun to introduce automatic drilling and riveting equipment in recent years, strivin...
