Study and Development of Reconfigurable and Multi-Station Auto Shaft Pressing and Assembling Machine for Small Gears

Abstract

Aiming at the shaft pressing and assembling process for steel shaft and small gear, which is frequent in toy gear reducer assembling, a reconfigurable and multi-station auto shaft pressing and assembling machine had been developed. In the machine, steel shaft and small gear are positioned in a pre-positioned fixture in advance. The assembling process is carried out in three stations simultaneously. It makes the machines efficiency become higher. Applying the reconfigurable design concept, the machine can be divided into basal modules and changeable modules. The changeable modules can be adjusted or replaced to make the machine fit for components of multifarious small gears and steel shafts with different length and diameter. Each module of the machine is introduced in detail and related problems are discussed in the paper.
