A centering mechanism of a super-fine machine comprises a mandrel, a fixing piece, a transition piece, a connecting shaft and a limiting seat. The limiting seat is of an annular hollow structure. A circular opening is formed in the middle of the annular hollow structure of the limiting seat. Another circular opening is formed in the middle, of the other side corresponding to the circular opening, of the annular hollow structure. The mandrel is installed inside the annular hollow structure of the limiting seat. One end of the mandrel stretches out of the corresponding circular opening, and a bearing inner ring to be machined is installed at the end. The other end of the mandrel is in contact with the end of the connecting shaft stretching into the corresponding circular opening. A through hole is formed in the interior of the connecting shaft. The through hole is expanded into a fixing hole at the end, stretching into the corresponding circular opening, of the connecting shaft. The external portion of the transition piece is fixedly installed in the fixing hole. One end of the fixing piece is fixedly installed in an inner hole of the transition piece, and the other end of the fixing piece stretches into an inner cavity of the mandrel. The centering mechanism can adapt to machining characteristics of the bearing inner ring and can cooperate with a spindle high in universality, and therefore the machining efficiency and the equipment universality of the super-fine machine are improved.
Description
technical field [0001] The invention relates to a centering mechanism of a super precision machine. Background technique [0002] Superfinishing is the finishing process of the finished surface with fine-grained oilstone mounted on the vibrating head. Superfinishing is generally arranged after the fine grinding process, and its machining allowance is only a few microns, which is suitable for machining the outer circle, inner circle, plane, groove surface and spherical surface of crankshafts, rolls, bearing rings and various precision parts. The superfinishing machine is a kind of precision equipment for this kind of processing. The oilstone is pressed against the rotating workpiece with a lower pressure to form a surface contact state. At the same time, the oilstone vibrates at a higher frequency in the axial direction to finely polish the workpiece. surface. The superfinishing machine can greatly improve the roughness in a short period of time. Because it is processed und...
