我厂加工生产的许多柴油机连杆中,都有大头孔倒角、小头车两端面的工序,如图1所示,这两道工序以前是在卧式车床上加工的,工序虽然简单,但操作人员劳动强度大。为此,我们设计了如图2所示的连杆大头孔倒角与车小头孔两端面夹具,应用在CA7620液压多刀半自动车床上,实现工件的夹紧→进刀→退刀→松开等半自动循环加工,操作简便,调整容易。大大减轻了劳动强度,提高了生产效率。 I plant processing and production of many diesel connecting rod, there are large hole chamfering, small car two ends of the process, shown in Figure 1, the two processes used to be in the horizontal lathe processing, although the process is simple, But the operator labor-intensive. To this end, we designed the connecting rod as shown in Figure 2 chamfering chamfering and car small head both ends of the fixture used in CA7620 hydraulic multi-knife semi-automatic lathe to achieve the workpiece clamping → feed → retract → → loose Open and other semi-automatic cycle processing, easy to operate, easy to adjust. Greatly reduce the labor intensity and improve production efficiency.
