卧式车床上加工薄壁长铝管件内孔的夹具设计

Design of Horizontal Lathe on the Process of Thin Wall Long Aluminum Pipe Fitting Jig

针对普通车床加工薄壁长铝管件内孔的难加工现状进行分析,介绍了一种在普通车床上通过夹具的改进设计来车削加工各种类型的薄壁长铝管件内孔的方法,并分析了该工装夹具的结构及工作原理,夹具使用过程中应注意的事项等。经过实践证明,该夹具使用方便且安全可靠,减轻了工人的劳动强度,生产效率比常规装夹要高出1倍,并且保证了薄壁铝管件内孔的尺寸精度与表面粗糙度。

Focus on the ordinary lathe machining thin-walled aluminum pipe fitting inner hole is difficult to machine analysis on the status quo of ordinary lathe,the paper presented a way that can turn all types of thin-wall aluminum pipe inner hole long,and analyzed its fixture structure and working principle,and some notices when using fixture,etc by using fixture design.After practice,this fixture is convenient,safe and reliable,and can reduce the labor intensity of the workers.The production efficiency is more than conventional clamping twice,such as thin-wall aluminum tube,and ensure the inner size precision of holes and surface roughness.
