摘要
在汽车零配件加工生产的过程中,如果使用人工上下料,则其不仅劳动强度大,而且效率低,工作环境也较差,有诸多不足。而使用自动上下料装置,则具有传送快速、定位精度高以及可以长时间连续作业,大大提高了生产效率。
本文拟设计一个适合于发动机配件生产线自动上料系统,该系统主要包括链传动系统和偏置曲柄滑块推杆机构两个部分。
在链传动系统中,选用合适的三相异步电机和与之匹配的减速器,再选择合适的间歇分割器,实现间歇传动,再通过一组链传动,从而实现预定减速。链传送带上的链条选择带翼的08B链条,翼上可以安装托盘,托盘上放置运输件,当链条转动时可以实现运输上料,链传送带上有张装置,可以保证从动链轮与主动轮在同一水平线上,且能保证链条的张紧。
在偏置曲柄滑块推杆结构中,在推杆位置末端放置接近开关传感器,当输送件到达指定位置时,接近开关感应输出信号给予步进电机信号,步进电机转动,带动设计的偏置曲柄滑块机构实现直线运动,完成推杆动作。设计的链传动与推杆形成配合完成自动上料系统。

Abstract
In the process of automotive parts production,Ifyou use the manual loading,then it is not only a Labor-intensive,but also inefficiencies,and theworking environment is poor, there are many deficiencies.However, the use of automatic loading and unloading devices,with transfer speed, high precision and long-time continuous operation, greatly improving production efficiency.
This paper intends to design a suitable engine parts production line automatic feeding systems. The system consists of two parts chain drive and the putt of offset crank slider mechanism.
In the chain of transmission system,, choice the appropriate of three-phase asynchronous motors and matching reducer. Then select the appropriate intermittent segmentation to achieve intermittent drive, and then achieve a predetermined deceleration through a set of chain drive. Chain links on the conveyor beltwill select the chain links ofwinged 08B, thewing may be mounted the tray. The tray is placed on the transport pieces. When the chain rotating, transporting the material can be achieved. There tensioning device on the conveyor of chain can ensure driven sprocket and activewheel at the same level, and can ensure that the chain tension.
In the the putt of offset crank slider mechanism,at the end of the push rod position, the sensor is placed close to the switch. When transporting pieces arrived at the designated location, proximity switch sensor output signal that is given to the stepper motor, the stepper motor rotating, and offset slider-crank mechanism drives by the design of linear motion. Then pushing rod action is completed. The chain drive and putting of designed formwith the completion of automatic feeding systems.
