我厂加工90°弯头两端时,曾使用美国工装夹具,存在装夹不便、加工稳定性不好等缺点,为此,我们重新设计了一套夹具,为车镗两用。加工精度高,调整方便。夹具有三面互相垂直的外框4(附图),工件装在两个互相垂直的V形架5上,用3根夹紧横梁3上的螺钉固紧,将A面座于镗床的工作台上,调整好位置后,紧靠B面在工作台上安装两个定位块(用镗床压板代替即可)。此时便可加工弯头的一个端面,加工
When processing two ends of 90 ° elbow in our factory, we have used American fixtures, which have the disadvantages of inconvenient clamping and poor processing stability. Therefore, we redesigned a set of fixtures for car boring. High precision, easy to adjust. The clamp has three outer frames 4 (the figure) perpendicular to each other. The workpieces are mounted on two V-shaped frames 5 perpendicular to each other, fastened with screws on the three clamping beams 3, , Adjust the position, close to the B side of the table to install two positioning block (boring press can be replaced). At this point can be processed elbow one end, processing
