我厂机械加工车间大件工段加工轴套类的工件时,采用了阶台式样板来代替划线,减少了辅助时间,提高了生产效率,并且保证了产品质量。工件的形状如图1,阶台式样板如图2中所示,是用10公厘厚的铁板,按工件形状制成。样板的两端用螺丝固定在支架上;这两个支架分别装在车头和车尾附近。另在车床横刀架的沟槽内,固定一个定位碰螺丝,来控制工件各个阶台的距离。这样就可以代替划线了。
I plant machining shop large section of the processing section of the shaft sleeve of the workpiece, using a step-style template instead of scribing, reducing the auxiliary time, improve production efficiency, and ensure product quality. The shape of the workpiece is shown in Figure 1. The stepped model is shown in Figure 2. It is made of 10mm thick iron plate according to the shape of the workpiece. Both ends of the template are fixed on the bracket by screws; these two brackets are respectively installed near the front and rear of the car. Another lathe horizontal turret in the groove, a fixed positioning touch screws to control the various stages of the workpiece distance. This will replace the crossed.
