無錫市江泰機械制造廠是一家專業(yè)從事外協(xié)件加工的企業(yè)，公司現(xiàn)采用加工中心加工紡織機械零件 皮圈架座上的三個孔，工裝時間長，加工成本高，效率不高。 關(guān)鍵詞 ：組合機床；多軸箱；三圖一卡；夾具設(shè)計 IV Abstract With the gradual improvement of automation, machine tool more and more in modern factories, machine tool based on mon ponents, together with the specific shape of the workpiece and process design special parts and fixtures, posed of semiautomatic or automatic dedicated machine. It is monly used multiaxis, multitool, multiprocess, multifaceted or multistation processing at the same time, the production efficiency several times or more higher than the general machine. Common ponents have been standardized for serialization, can be flexibly configured, you can shorten the design and manufacturing cycle. Therefore, the bination of machine bines the advantages of low cost and high efficiency has been widely used in mass production, and can be used to form an automatic production line. The design for the apron mountings drill special machine tools, pleted three hole machining. Mainly the following aspects: (1) to develop a process plan. Learn about the processing characteristics of the machined parts, precision and technical requirements, the positio
