摘要
在FMS的应用中,工作台叉取结构是运输小车的主要结构,负责运送装载工件的工作台。在运送重载工件时,叉取臂的刚性不足经常会引起运送的工作台无法精确定位在主机的预备位上,使主机运行发生故障而报警,影响FMS运行的稳定性。本文针对这个问题,设计了一种高刚性的叉取臂,详细论述了该叉取机构的结构原理,并通过有限元分析对其刚性进行了检测比较。该刚性叉取臂可以有效改善上述问题。
Intheapplication of FMS, the fork structure is the main structure of the transport car, which is responsible for transporting the pallet with part. Ill the delivery of heavy parts, the low rigidity of the fork arm will cause the pallet to be can t accurately positioned in the machine's reserve position, so that the failure of the machine operation and alarm, affecting the stability of FMS. In order to solve this problem, this paper designs a kind of fork arm with high rigidity, and discusses the structure principle of the fork, the finite element analysis is carried out to compare the rigidity of different fork arm. The new fork arm can improve the problem effectively.
