摘要: 在发动机的活塞连杆装配过程中,活塞卡簧的压装是一个难点,本文介绍的自动工作站是快速安装活塞卡簧并验证其安装精度的专用工作站。活塞和连杆是发动机运转中的关键零部件,活塞的主要作用是承受汽缸中的燃烧压力,并将此力通过活塞销和连杆传给曲轴,而本文要介绍的卡簧恰恰是保证活塞和连杆连接的关键部件,他们的连接也对整个发动机的运转以及使用寿命起到至关重要的作用。在本文中,我们就详细介绍一下工作站的设计及其关键结构。
Abstract: In the process of assembling the piston connecting rod of engine, it is difficult to press the piston clip spring. The automatic workstation introduced in this paper is a special workstation to quickly install the piston clip spring and verify its installation accuracy. Piston and connecting rod are the key parts in engine operation. The main function of piston is to bear the combustion pressure in cylinder, and transmit the force to crankshaft through piston pin and connecting rod. The circlip introduced in this paper is the key part to ensure the connection of piston and connecting rod, and their connection also plays a vital role in the operation and service life of the whole engine. In this paper, we will introduce the design and key structure of the workstation in detail.

1 活塞连杆整线概述
活塞连杆线包含活塞上料、连杆上料、活塞销自动推出、活塞连杆装配、卡簧压装、不合格料下线、连杆拧紧胀开、活塞连杆自动喷码标识、活塞连杆下线等工位。整线节拍7.5s。本文所介绍采用全自动压装的形式进行卡簧压装,在提高节拍的同时,也提升了压装合格率。
整线的工作流程如下:操作工1站在料架前通过智能料架提供的信号,从料架上拿取相应的活塞和连杆,放置在工作台上,然后操作工1将活塞销推出,将连杆放入活塞,随后再将活塞销推回,然后将活塞连杆机构挂在辊道的托盘上,按下手动放行按钮后,托盘将活塞连杆输送至下一工位,到达此工位后,活塞底部布置的扫码器扫描产品信息后继续放行至下一卡簧压装工位,卡簧压装工位自动将前端卡簧压入活塞中,然后通过几个探针对卡簧是否安装到位进行判断,合格产品继续向后到连杆胀开工位。……
