机械工人53年第10期和56年第10期已经介绍过两种自动抬刀装置,现在我再来介绍一种比较简单的自动抬刀装置。这种装置如附图所示。1是顶杆。2和3是两个紧圈,用止头螺丝固定在顶杆上,可以任意调整位置。4是带动环,固定在滑枕上,随滑枕作往复运动。5是支架,固定在床身上不动,顶杆就是穿过支架上的孔。6是摩擦块。7是弹簧。8是调整螺丝。由于弹簧的压力。使摩擦块和顶杆表面压紧,产生一定的摩擦力。这样顶杆在支架孔中移动就需要一定的力量才行。调整螺丝8用来调整弹簧压力,因而也调整了摩擦力的大
Mechanical workers 53 years 10 and 56 years 10 have introduced two kinds of automatic lift knife device, and now I will introduce a relatively simple automatic lift knife device. Such a device is shown in the drawing. 1 is the top rod. 2 and 3 are two tight circle, with the head screws fixed on the mandrel, you can adjust the position. 4 is driven ring, fixed on the ram, with the ram reciprocating motion. 5 is a bracket, fixed on the bed, the mandrel is through the hole on the bracket. 6 is the friction block. 7 is a spring. 8 is adjusting screw. Due to the pressure of the spring. The friction block and mandrel surface compression, have a certain amount of friction. This ram moves in the bracket hole will need some power Caixing. Adjustment screw 8 is used to adjust the spring pressure, thus adjusting the friction
