我厂生产的工农七型手扶拖拉机上,有很多齿轮,这些齿轮的毛刺清理,过去是采用手工修锉,效率低,是生产中的薄弱环节。要突破这一关,必须实现齿轮修毛刺机械化。我们学习了毛主席关于“有所发现、有所发明、有所创造、有所前进”的教导后,认识到我们一定能革掉手工修锉落后的命,路是人走出来的,一定能造出一台结构简单,生产效率高的修毛机。我们运用三结合的方法,经过一年的时间,数十次 There are a lot of gears on the seven-type walking tractor for workers and peasants produced by our factory. The burr cleaning of these gears used the manual repair and was inefficient. It is a weak link in production. To break through this barrier, it is necessary to realize gear repair burr mechanization. After learning from Chairman Mao’s teachings of “discovery, invention, creation, and advancement”, we realized that we must be able to manually repair the backward life. Must be able to create a simple structure, high production efficiency of the hair trimming machine. We use the three-combination method, after a period of dozens of times,
