A kind of super precision machine adjustment mechanism

Abstract

A superfinishing machine adjusting mechanism comprises an oscillating shaft, an oscillating component and a transmission shaft, wherein the oscillating shaft is provided with an oscillating shaft head; a spherical roller bearing is arranged on the oscillating shaft head; the transmission shaft is fixedly connected with the oscillating component; the oscillating component is provided with an oscillating surface; the transmission shaft is rotatably engaged with the spherical roller bearing via the oscillating surface of the oscillating component; the oscillating surface is a cylindrical surface; the oscillating shaft head and the spherical roller bearing mounted on the oscillating shaft head extend into the cylindrical surface through a passage formed in the upper part of the oscillating surface; and the outer surface of the spherical roller bearing rotatably engaged with the cylindrical inner wall of the cylindrical surface. After adopting the adjusting mechanism, a superfinishing machine can be adapted to different machining environments, can be applied to superfinishing the inner ring and outer ring of a bearing at the same time, and is convenient and accurate in process action adjustment and high in reliability.

Description

technical field [0001] The present invention relates to a superfinishing machine adjustment mechanism, more specifically, to an adjustment mechanism for adjusting the oil stone swing mechanism in a superfinishing machine for superfinishing the inner and outer rings of a bearing. 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 i...

Problems solved by technology

In the existing superfinishing machine technology, due to the different characteristics of the processed bearing inner ring and bearing outer ring, the superfinishing machine used to process the bearing inner ring and the superfinishing machine used to process the bearing outer ring need to be separated. Design and purchase, or use one piece of equipment, but there are a large number of different device structures for different processing workpieces on the equipment, which need to be replaced from time to time, resulting in high cost and low efficiency
