The present invention provides a bearing full-automatic up-down material processing and precision detection integrated device, comprising: a marking machine main body, a bearing fixed pulley, and an electric cylinder. Two groups of the bearing fixed pulleys are axially connected to the top of the marking machine main body. Two groups of intermediate gears are axially connected to the inner middleof the marking machine main body. The lifting plate and the marking machine main body are in slip connection. Four pairs of swinging connecting rods are hinged in the inner middle of the marking machine main body. One group of outside diameter measuring blocks is hinged with the top of each pair of the swinging connecting rods. One group of diagonal draw bars is hinged with the middle of each of the four groups of inner swinging connecting rods. The bottom of the diagonal draw bar is hinged with the lifting plate. Outside and inside diameters of a bearing are measured during marking, and outside and inside diameter size precision of the bearing is monitored in real time, so that outgoing quality of the bearing is ensured. Further, marking and precision detection are integrated, so that production efficiency is significantly improved, thereby better implementing production automation.
