我厂在修理滚齿机的过程中,解决后立柱滑架轴承孔中心与工作台中心孔的同轴度是靠钳工刮研找正的方法。既费时费力,精度又难保证。为此,我们采用机床自身镗孔工艺,既简单又保证了精度。图1是修理5330滚齿机的示意图。镗孔胎座9用T型螺钉固定在工作台圆盘10上,刀杆8用螺钉6固定在镗孔胎座9上,最后把刀盘5固定在 I plant repair hobbing machine in the process, to solve the post-column bearing bearing center hole and table center hole coaxiality is fitter scraping method to find out. Both time-consuming and labor-intensive, accuracy is difficult to guarantee. To this end, we use the boring machine itself, both simple and accurate. Figure 1 is a schematic illustration of a 5330 hobbing machine. Boring seat 9 with a T-shaped screw fixed to the table disc 10, the arbor 8 is fixed with a screw 6 on the boring seat 9, and finally fixed to the cutter 5
