对于鄂板工件(图1),在车床或铣床上无法加工,而刨床只能竖直和横向进刀,直接加工也十分困难。为此,我们革新成功自动刨外圆弧面装置,在牛头刨床上直接加工,效果较好。刨出的外圆弧面光滑平整,光洁度可达6。从而减轻了劳动强度,去掉了钳工锉修弧面的工序,使工效提高两倍多。自动刨外圆弧面装置的结构如图2所示,由压板 For the jaw workpiece (Figure 1), in the lathe or milling machine can not be processed, while the planer can only be vertical and horizontal feed, direct processing is also very difficult. To this end, we successfully innovate automatic planing arc device, directly in the shaper bed processing, the better. Scraped out of the arc surface smooth, smooth finish up to 6. Thereby reducing the labor intensity, eliminating the fitter file arc process, so that work efficiency increased more than twice.
