我厂经过几年的生产实践,在编制单轴自动车床调整卡片时,已全部采用图表分析法来确定空行程占用循环格数,这种方法简单、迅速、准确,能保证自动车床各部分运动衔接紧凑,减少辅助时间,提高生产效率。图表分析法就是既要画图,又要经过分析。在确定空行程占用循环格数前,先确定空行程的计算格数。我们以C1312单轴六角车床说明书上的进气阀内座加工为例,来介绍图表分析法的使用。1 先根据回转刀架工作程序的先后画出附图中A-A运动曲线,并在曲线上标出回转刀架的各工步名
I plant after several years of production practice, in the preparation of uniaxial automatic lathe adjustment card, have all used chart analysis to determine the empty trip cycle number, this method is simple, rapid and accurate, to ensure that all parts of automatic lathe movement Cohesion, reduce auxiliary time, improve production efficiency. Chart analysis is both drawing, but also through analysis. Before determining the number of cycles occupied by empty travel, determine the number of blank travel calculation. We C1312 single-axis hexagonal lathe manual instructions on the valve seat processing as an example to introduce the use of chart analysis. 1 first according to the working sequence of the rotary turret draw the drawing in the A-A movement curve, and the curve marked rotary turret of the step names
