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.

On Adaptable Design of Auto Assembly Machine Product Platform for Small Shaft and Sleeve Subassemblies

“…The General Structure Design of the Product Platform. In order to be suitable for the auto assembling of multifarious small shaft and sleeve subassemblies, the structure of the product platform is designed on the basis of the existing product platforms of multi-stations auto shaft pressing and assembling machine for small gears [2,3] and auto assembly machine for pens. The chain is used as the main transmission in both of the product platforms, and then the automatic assembling of subassemblies is realized through installing related accessories on the chain and distributing feeding devices or related executive devices on both sides of the product platforms.…”

“…In production of toys, stationery and other light industrial products, there are a lot of small sleeves and shafts that need to be assembled into subassemblies or products [1,2]. They are multifarious, and shape and quantity of their parts are different.…”

“…They are multifarious, and shape and quantity of their parts are different. Multi-stations auto shaft pressing and assembling machine for small gears is used for the assembly of steel shafts and small gears [2,3]. But it can only be suitable for single subassembly for not considering more individuation market demand.…”

Development of Parameterized Design System of Auto Assembly Machine Product Platform for Small Shaft and Sleeve Subassemblies

“…There are multifarious small shaft and sleeve subassemblies in toys, stationery and other light industrial products [1,2]. The study on adaptable design of auto assembly machine product platform for small shaft and sleeve subassemblies has been described in another paper.…”

“…The study on adaptable design of auto assembly machine product platform for small shaft and sleeve subassemblies has been described in another paper. The product platform is developed on the basis of the existing product platforms of multi-stations auto shaft pressing and assembling machine for small gears [2,3] and auto assembly machine for pens. The desire for the product platforms is that it can be suitable for the automatic assembling of multifarious small shaft and sleeve subassemblies, and can be upgraded and quickly respond to the individuation market demand.…”
