TL;DR: In this article, an automatic feeding device of a gear shaping machine is described, which is composed of a containing plate, a transfer assembly, a workbench, the gear shaping machines, a mechanical arm control table, a first mechanical arm, a second mechanical arm and a third mechanical arm.
Abstract: The invention discloses an automatic feeding device of a gear shaping machine. The automatic feeding device is composed of a containing plate, a transfer assembly, a workbench, the gear shaping machine, a mechanical arm control table, a first mechanical arm, a second mechanical arm, a third mechanical arm and a fastening assembly. The mechanical arm control table drives the first mechanical arm tocarry to-be-machined workpieces on the containing plate below the first mechanical arm to the transfer assembly. After finished products already machined by the gear shaping machine and located on the workbench are unscrewed through the fastening assembly, the mechanical arm control table drives the second mechanical arm to take down the finished products, then the third mechanical arm feeds theto-be-machined workpieces located on the transfer assembly to the workbench, the to-be-machined workpieces are fixed to the workbench through the fastening assembly, and gear machining of the next time is carried out with the gear shaping machine; and thus the effects of achieving gear machining automation and improving machining efficiency are obtained.
TL;DR: In this paper, an economic process design for the gear shaping of Austempered Ductile Iron (ADI) gears is presented, based on computer-aided force measurements and wear tests.
