The output end of the cylinder is connected to a disc, and the middle thread of the disc is connected to a screw, and the side of the disc is hinged with a clamping assembly; when in use, when the fixed plate descends, the fixed plate will pull one end of the connecting rod to descend synchronously, and the other end of the connecting rod will pull the clamping arm closer to the middle, so that the clamping arm can use the clamping plate to clamp and position the outer ring of the bearing, and when the fixed plate rises, the fixed plate will pull one end of the connecting rod to move up synchronously. At this time, the other end of the connecting rod will pull the clamping arm to open outward, so that the clamping arm can use the clamping plate to loosen the outer ring of the bearing, and it is also convenient to adjust the clamping of bearing outer rings of different diameters.

[0004] However, the rotor and the bearing cylinder need to be cleaned and lubricated when assembled. Most of the existing assembly and positioning devices still require manual cleaning and lubrication, which is time-consuming and labor-intensive. In addition, the rotor and the bearing cylinder are very heavy, and manual handling is time-consuming and labor-intensive, and can easily injure workers. Utility Model Content
