Superfinishing machine

Abstract

A superfinishing machine comprises a machine tool bed component, a spindle box component, a superfinishing transmission mechanism, a superfinishing mechanism, a pressing mechanism, a feed mechanism, a universal spindle component and an adjustable spindle component, wherein the superfinishing mechanism is mounted on the superfinishing transmission mechanism and is driven by the superfinishing transmission mechanism; the adjustable spindle component is mounted at an end part of the universal spindle component; the adjustable spindle component and the superfinishing mechanism are located on the same side of the spindle box component; the pressing mechanism and the feed mechanism are mounted at the lower part of the spindle box component and are located on the same side as the adjustable spindle component; the pressing mechanism, the feed mechanism and the adjustable spindle component together form a space for accommodating a to-be-processed workpiece; and the superfinishing mechanism is located above the space. The 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, is well adapted to different objects of machining, is convenient and accurate in process action adjustment and high in reliability, and can coordinate the functions of all the components to realize high-precision and high-quality superfinishing.

Description

technical field [0001] The invention relates to 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 under low pressure, the surf...

Problems solved by technology

[0006] The technology disclosed in this document solves the problem of adaptability to different processing objects proposed above to a certain extent, but adopts the technical solution that the electric spindle and the swing head lifting mechanism are two sets, which are respectively installed above the working translation mechanism. , complex equipment, low efficiency, high cost, adaptability to different processing objects and coordination of functions of various components to achieve high-precision and high-quality ultra-finishing, the above-mentioned literature disclosures and prior art cannot solve it well

[0007] 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 workpieces on the equipment, which need to be replaced from time to time, resulting in high cost and low efficiency
