目前电机轴承内·外盖钻模均采用传统式的结构,就是钻模的外形及尺寸与工件的外形及尺寸相同。工人操作时凭眼睛看“凸耳”是否对齐,这样钻出来的孔不容易对准“凸耳”的中心,甚至偏离很多。我厂在试制 YB80电机时,对该钻模在结构上作了改进,达到了很好的效果。操作极为方便,深受工人们的欢迎,加工出来的孔完全符合图纸要求。 At present, the motor bearing inner and outer cover die are used in the traditional structure, that is, the shape and size of the die and the workpiece shape and size of the same. When the worker operates, he or she can see if the “lugs” align with the eyes, so that the drilled holes are not easily aligned with the center of the “lugs” or even deviate from each other. I plant trial YB80 motor, made on the structure of the drill improved to achieve good results. Very easy to operate, welcomed by the workers, processed holes in full compliance with the drawings requirements.
