The invention discloses a lifting appliance for machining a bearing outer ring. The lifting appliance comprises a lifting cylinder; the at least two supporting plates are symmetrically fixed to the side wall of the lifting cylinder, the lower surfaces of the supporting plates are connected with chains through mounting blocks, and clamping blocks for lifting the outer ring are arranged at the lower ends of the chains; the extension adjusting mechanism is arranged at the lower end of the inner side of the lifting cylinder and is in running fit with the clamping block through a first adjusting bolt, and when the outer ring is lifted, the chain is extended; the grapnel is rotationally mounted at the lower end of the outer surface of the lifting cylinder; through the arrangement of the sliding rod, the fixed adjusting block, the movable adjusting block and the grabbing hook, the clamping and loosening actions can be automatically completed without additional driving parts, the use convenience is improved, meanwhile, through the multiple first adjusting holes and second adjusting holes, adjustment can be conveniently conducted according to bearing outer rings with different outer diameters, and the working efficiency is improved. And different bearing outer rings are hoisted.

    本发明公开了一种轴承外环加工用吊具,包括:吊筒;至少两处的支板,对称固定于吊筒的侧壁,且所述支板下表面通过安装块连接有链条,所述链条下端设置有对外环吊起的夹块;伸展调节机构,设置于吊筒内侧下端,且其与夹块通过第一调节螺栓进行转动配合,在吊起外环时,使链条进行伸展;抓钩,转动安装于吊筒外表面下端;通过设置有滑动杆、固定调节块、活动调节块及抓钩,本装置不需要另外的驱动部件,即可自动完成夹紧、松开的动作,提高了使用的便捷性,同时通过多个第一调节孔及第二调节孔,便于根据不同外径的轴承外环进行调节,对不同的轴承外环进行吊起。
