M8861磨床是加工轴承内滚道的半自动机床,过去靠手工上下料,劳动强度大,每人只能看一台。我厂一成品车间三结合革新小组发扬了自力更生、艰苦奋斗的革命精神,自己动手,制成了机械手,实现了自动上下料。在此基础上又将2台M8861磨床联成粗、细磨机组联线,从而减轻了体力劳动、节省了人力,做到了一人双机,并大大减少了工序间的搬运量。 M8861粗细磨床共两台,均采用电磁无心卡具。附图系M8861机组联线第一台机床执行机构(与第二台相同)示意图。所有机件均在导 M8861 grinding machine is a semi-automatic machine tool bearing inner raceway, in the past by manual loading and unloading, labor-intensive, each person can only see one. I plant a finished product workshop three innovation team to promote self-reliance, hard work and revolutionary spirit, do it yourself, made a manipulator, to achieve the automatic loading and unloading. On this basis, two M8861 grinding machines are combined into a coarse and fine grinding unit to be connected, thereby reducing manual labor, saving manpower, achieving one person and two machines, and greatly reducing the handling volume between processes. M8861 a total of two grinder, are used electromagnetic centerless fixture. The drawing is the schematic diagram of the first machine tool actuator (same as the second one) of the M8861 unit. All parts are in the lead
