在车床上工作的同志们都知道:车床纵向走刀时都是机动的,即溜板箱从床尾自动走向床头;而纵向退刀时则是手动的,即用手将溜板箱从床头摇回床尾。走刀次数越多,则摇回溜板箱的次数也就越多,因而使工人感到劳累。我厂钳工郑贤长同志和技术员共同研究出一种纵向退刀的自动装置。经使用证明,效果良好,现在把它介绍出来,供大家参考。纵向退刀自动装置的机构如附图所示。1是床身。28是溜板箱,在它的左侧面装一个轴架9;轴架9的孔内装有两个轴向滚动轴承和两个径向滚动轴承,退刀轴3就固定在轴承的孔内。8是轴承盖,用螺钉固定在轴架9上。退
The comrades working on the lathe know that the lathe moves in the longitudinal direction when it is maneuvered, that is, the slide box automatically goes to the head of the bed from the end of the bed, and when the longitudinal retraction is manual, the slide box is manually removed from the bed Shake your head back to bed. The greater the number of passes, the greater the number of shakes to the pallets, which makes the worker feel tired. Zheng Xianchang, my factory locksmith comrades and technicians jointly developed a longitudinal retraction of the automatic device. The use of proof, the effect is good, now introduce it for your reference. Longitudinal retractor automatic mechanism as shown in the figure. 1 is the bed. 28 is a sled box, on the left side of which is mounted a pedestal 9; the pedestal 9 is provided with two axial rolling bearings and two radial rolling bearings, and the withdrawal shaft 3 is fixed in the hole of the bearing. 8 is a bearing cap, with screws fixed to the shaft frame 9.
