我厂生产的各种旋转窑中,有许多大型内、外球面轴承需要加工。过去是在车床横拖板上装上一定圆弧半径的靠模(图1),利用滚子在圆弧槽内移动而达到加工目的。但由于圆弧槽的制造不很正确,而且滚子在槽中不司能没有间隙,故加工出来的球面精度不高,以致装配时要钳工化去不少刮配时间。此外,要使滚子能紧贴着圆弧靠模移动,因此在拖板上挂了很重的重物,以致滚子在槽内移动困难,必须用人力不断敲击拖板,震动滚子,才能使它沿着圆弧槽移动。而且每块靠模仅能加工一定半径的球面轴承,如果尺寸改变,就要另制靠模。针对这种落后的加工方式,我车间技术组在领导
I plant a variety of rotary kiln, there are many large, spherical bearings need to be processed. In the past is mounted on the horizontal lathe lathe radius of a certain model (Figure 1), the use of roller movement in the arc slot to achieve processing purposes. However, due to the manufacture of circular groove is not very correct, and the roller can not slot in the slot can not gap, so the accuracy of the processed ball is not high, so that the assembly time to clamp a lot of scraping time. In addition, to make the roller can move close to the circular arc mode, so the heavy weight hanging on the pallet, so that the roller movement in the tank is difficult, we must continue to tap the pallets manpower, vibration roller , To make it move along the arc slot. And each model can only be processed by a certain radius of the spherical bearings, if the size change, it is necessary to make a separate model. In response to this backward processing methods, I workshop leadership team
