我厂在制作细纱机零件皮辊芯子时,拉S形油槽是一项技术要求较高的工序,我们改进了一套工具,在C620车床上加工使用。结构简单、操作方便,效率高、质量好,深受操作者欢迎。工具的结构和原理如图所示,锥柄轴1装在C620车床主轴孔内,用拉杆螺丝加固,伞齿轮2(m=3.5,z=30)装在锥柄轴1中部台阶上,以平键和螺母4紧固,锥柄轴1前端装有三爪法兰5和三爪卡盘6。伞齿轮7(m=3.5,z=30)通过心轴10装在支架8上,随同底板3固定在机床床身导轨17上。
When making the roller core of the spinning frame, the S-shaped oil sump is a more technically demanding process. We have improved a set of tools to process the C620 lathe. Simple structure, easy operation, high efficiency, good quality, welcomed by the operator. The structure and principle of the tool are shown in the figure. The taper shank 1 is installed in the spindle hole of the C620 lathe and is reinforced with tie rod screws. The bevel gear 2 (m = 3.5, z = 30) is mounted on the middle step of the taper shank shaft 1 The flat key and the nut 4 are fastened, and the front end of the taper shaft 1 is provided with a three-jaw flange 5 and a three-jaw chuck 6. The bevel gear 7 (m = 3.5, z = 30) is mounted on the bracket 8 via the spindle 10 and is fixed to the machine bed guide rail 17 along with the bottom plate 3.
