我厂在大搞技术革新和技术革命运动中,设计制造成功了一种车削内螺纹的自动进刀装置,解决了15吨载重汽车后桥减速器壳内螺纹的加工问题。过去,四吨交通牌载重汽车减速器壳的内螺纹,是在一台普通车床上加工的,一天只能加工10个左右,革新后,加工15吨汽车减速器壳内螺纹的工效提高三、四倍左右,提高了自动化程度,减轻了劳 I plant in major technological innovation and technological revolution movement, the design and manufacture of a success of the internal thread turning automatic feed device to solve the 15-ton truck rear axle reducer shell thread processing problems. In the past, four-ton traffic license truck truck reducer internal thread is processed in an ordinary lathe, the day can only process 10 or so, after the reform, the processing 15 tons of automotive reducer shell thread to improve the efficiency of three, About four times, improve the degree of automation, reduce labor
