A multifunctional end effector for automatic drilling and riveting machine

Abstract

The invention discloses a multifunctional end executor of an automatic drilling and riveting machine. The multifunctional end executor used as the main end executor of the automatic drilling and riveting machine is used for aircraft plates and can perform the operations including positioning, drilling, countersinking, dust removing and sprigging, the maximum work cycle speed is 15 per minute and the end executor can cooperate with a tight upsetting head to achieve the pressing riveting function. The multifunctional end executor has the following advantages that a drilling unit, a milling unit, a hole measuring unit and a sprigging unit are sequentially distributed on a base X-axle large-lead high-speed screw rod; a cutter changing unit and a rivet feeding unit are arranged, a visual measurement unit is adopted and the servo driving is used. The end executor is compact in structure, reliable, highly effective, economic and environmentally friendly, the drilling precision satisfies the technical requirements for hole position precision, verticality, the finish degree and the like; the riveting quality satisfies the technical requirements for riveting strength, the interference value, sealing and the like.

Description

technical field

[0001] The invention relates to the field of machining, in particular to a multifunctional end effector of an automatic drilling and riveting machine. Background technique

[0002] In the assembly of metal components such as aircraft panels, riveting is still one of the most important connection methods at present, occupying a huge workload. Traditional manual riveting has poor working conditions and low production efficiency. The quality of riveting depends heavily on the experience and technology of workers, and does not meet the development requirements of aircraft digital assembly. Therefore, it is imperative to use automatic drilling and riveting machines to replace manual operations. However, the principle and structure of high-end automatic drilling and riveting machines are quite complicated. At present, only a few manufacturers in Europe and the United States have the ability to develop and manufacture, such as EI, GEMCOR, BROETJE, etc. The developme...
