摘　　要：针对现有砂芯制作工艺流程中人工修芯生产效率低、砂芯外形一致性差的问题,设计了一种自动砂芯修芯系统。基于双针浮动打磨技术和工业机器人技术设计了打磨机构,实现对砂芯坯缝线的去除。设计了带有弹簧定位夹紧机构的工装板,以实现砂芯阵列的定位与夹紧。设计了倍速链机构,以直线循环方式实现工装板在各个工位的流转与顶升定位。测试结果表明:产线运行可靠,修芯速度为16 s/个,有效改善了砂芯外形一致性,保证了铸件的质量。Aiming at the problems of low production efficiency and poor consistency of sand core shape in the existing sand core manufacturing process,an automatic sand core dressing system was designed.Based on double needle floating grinding technology and industrial robot technology,a grinding mechanism was designed to remove the gap of the sand core blank.The tooling board with spring positioning and clamping mechanism was designed to realize the positioning and clamping of the sand core array.The speed chain conveyor was designed to realize the circulation and jacking positioning of tooling board in each station in a straight-line cycle.The test results showed that the production line run reliably and the core repair speed was 16 seconds per piece,which effectively improved the shape consistency of the sand core and ensures the quality of the castings.
