我厂过去车制刹根螺丝,每次走刀到一定的地位时,必须关车而用人力来拉动车头。这样转速很不一致,容易崩坏刀头,同时工件质量很难掌握,工作效率也很低。俞梅林和戎兆华两同志,改进了快速自动退刀装置,提高了工作效率和产品质量。快速自动退刀装置的构造如附图。改进方法和操作方法如了:(一)将车床小刀架的丝杆,根据车退拔的方法加以更动;即拆除丝杆⑥后端的轴瓦。另外制一个外圆较小的轴瓦④旋上,再旋紧丝杆末端的螺
In the past, our factory brake brakes the screws, each time you go to a certain position, you must turn off the car and use human power to pull the front. This speed is very inconsistent, easy to collapse the head, while the quality of the workpiece is difficult to grasp, the work efficiency is very low. Yu Meilin and Rong Zhaohua two comrades, improved rapid automatic retraction device, improve work efficiency and product quality. Rapid automatic retractable device structure as shown in the drawings. Improved methods and methods of operation, such as: (a) the lathe knife holder screw, according to the method of car pull back to be changed; that is, remove the screw ⑥ rear bearing. Another system of a smaller cylindrical bearing ④ rotating, and then screw the end of the screw
