摘要
以往缸体坡口加工时,利用手工划线和手工修制的方法进行加工,存在坡口加工时间长、加工效率低、坡口处焊接质量不稳定的问题,通过UG软件对缸体及坡口进行三维模型的建立,通过UG数控编程并对坡口进行数控机床试加工,对加工完成的坡口进行产品试装配和焊接,根据试装配和焊接情况,利用加工完成的零件对三维模型进行修订,得到最终的三维模型图,将以往手工修制坡口的方式调整为数控机床加工,使缸体坡口加工时间由原来的1.6 h/件缩短至0.6 h/件,同时,缸体坡口通过数控机床加工,一致性得到了提高和保证,在缸体装配时,缸体坡口和筒体之间对接良好,焊接质量提高,整体上提高了缸体坡口的加工、对接效率,提高了缸体坡口的加工质量和焊接质量。
In the past,the groove machining of the cylinder was processed by manual scribing and manual repair,which existed the problems of the long groove machining time,the low processing efficiency,and the unstable welding quality at the groove.The three-dimensional model of cylinder and the slope were built by UG software,and the groove was tested by CNC machine tool through UG numerical control programming.The finished groove was subjected to product test assembly and welding,according to the trial assembly and welding situation,the processed parts were used to revise the three-dimensional model to obtain the final three-dimensional model diagram,and adjusted the previous manual bevel repair method into CNC machine tool processing,so that the cylinder block bevel processing time was shortened from the original 1.6 hours/piece to 0.6 hours/piece.At the same time,the cylinder groove was machining through the CNC machine tool,the consistency has been improved and guaranteed.When the cylinder body is assembled,the butt joint between the uniformity was improved and ensured,when assembled cylinder,the joint between the cylinder groove with shell was good,and the welding quality was improved,so the efficiency of machining and joint of cylinder groove was overall improved,and the quality of machining and welding of cylinder groove was also improved.
