1制壳机械手简介精密铸造制壳工序现场环境差、劳动强度大、效率低,产品的品质难以控制,对一线操作工人的操作技能要求高。为解决上述问题,经过长期的现场调研,开发出了第一台三(四)臂制壳机械手。三(四)臂制壳机械手具有型壳装卸方便、沾浆、淋砂均匀性好等优点,并能改善操作者的工作环境,减轻了工人的劳动强度,大大提高生产效率。2主要组成部分三(四)臂制壳机械手由机械部分和电气部分组成。机械部分在回转底座上装有3个臂,回转底座可以连续 1 Shell Mechanical Introduction Shell casting process shell site environment is poor, labor-intensive, low efficiency, difficult to control the quality of the product, the operational skills of front-line workers demanding. To solve the above problems, after the long-term field investigation, the first three (four) arm shell manipulator was developed. The three (4) arm shell manipulator has the advantages of convenient loading and unloading of the shell, good dip consistency and good sand drench uniformity, and can improve the working environment of the operator, reduce the labor intensity of the worker and greatly increase the production efficiency. 2 main components Three (four) arm shell manipulator consists of mechanical parts and electrical components. The mechanical part is equipped with 3 arms on the swivel base and the swivel base can be continuous
