The molecular pump hoisting and positioning device comprises an outer ring assembly and an inner ring assembly, the inner ring assembly is arranged in an inner ring groove of the outer ring assembly, a gap is formed between the outer surface of the inner ring assembly and the inner ring groove of the outer ring assembly, and the inner ring assembly is arranged in the gap. Multiple sets of radial rolling steel balls are arranged in the gap in the circumferential direction of the inner ring groove, the outer ring assembly is divided into an outer ring semicircle A and an outer ring semicircle B. One end of the outer ring semicircle A is connected with one end of the outer ring semicircle B through a hinge. The other end of the outer ring semicircle A is connected with the other end of the outer ring semicircle B through a clamping device, and the inner ring assembly is divided into an inner ring sleeve ring A and an inner ring sleeve ring B. The device has the advantages that posture conversion and radial arbitrary posture adjustment in the molecular pump assembling process can be achieved, and the relative positions of the mounting holes and the fixing holes can be rapidly adjusted when the molecular pump is hoisted.
