Abstract

The invention relates to a multi-specification selectable rivet automatic inserting device, and relates to the technical field of riveting. The multi-specification selectable rivet automatic insertingdevice solves the problems that according to existing riveting automation equipment, size adaptation is poor due to a rivet insertion module, the rivet inserting compensation function does not exist,and therefore the implementation of automatic riveting is greatly limited. The multi-specification selectable rivet automatic inserting device comprises a rivet inserting unit and a rivet selecting unit, the rivet inserting unit comprises a rivet inserting box, a rivet inserting box cover, a vision positioning system, a rivet inserting air cylinder, a position detection switch and a nail clampingdevice, the vision positioning system and the position detection switch are sequentially installed on the side wall of the rivet inserting box from top to bottom, the rivet selecting unit comprises arotating motor, a rivet selecting support, a guide support, a reset detecting switch, a connecting plate, N rivet passing detecting switch and N rivet sending pipes, the rivet selecting support and the guide support are coaxially arranged at the upper portion of the rotating motor from bottom to top, the tail ends of the N rivet sending pipes communicate with second through holes of the guide support, and the upper portion of each rivet sending pipe is provided with one rivet passing detecting switch.

Description

technical field [0001] The invention relates to the field of riveting technology, in particular to an automatic rivet insertion device for optional rivets with multiple specifications. Background technique [0002] As a commonly used technology, riveting is widely used in various fields such as aerospace product manufacturing and automobile manufacturing due to its reliable and simple connection. However, the riveting workload is large, and most of the domestic riveting relies on manual riveting or special tools, which is labor-intensive and the working environment is relatively harsh. For the automated equipment used in riveting, the most commonly used is the automated riveting equipment for aircraft skins. In automated riveting, automated nail insertion is an essential part of it, and usually appears as a module of a complete set of end effectors. Although the entire set of equipment integrates processes such as nail feeding and riveting, it lacks adaptability to rivets o...
