一种用于砂芯托盘的精确定位装置

摘要

Core transport tray accurate positioning in the sand core automated production line is important for sand core is prone to be damaged in the process of robot placing and grapping the sand core. This article describes a four-sided clamping mechanism for precise positioning of the pallet, and introduces the positioning, clamping device and pneumatic control device of the system. The frequency conversion conveying roller table carries on the initial thick positioning to the sand core tray, the four sides clamping mechanism realizes the accurate localization. It can be seen that the system can meet the requirements of positioning accuracy of the pallet and avoid the problem that the robot jig can damage the sand core due to the inaccurate position of the pallet.%针对铸造厂砂芯自动化生产线上机器人上料和下料工位放置砂芯的托盘需要精确定位的问题,介绍一种用于托盘精确定位的四面夹紧机构,包括定位和夹紧装置、气动控制装置;变频输送辊道对砂芯托盘进行初次粗定位,四面夹紧机构实现精确定位.现场运行表明,该系统能满足托盘的定位精度要求,避免了由于托盘定位不准可能造成机器人夹具损坏砂芯的问题.
