Superfinishing machine control system

Abstract

A superfinishing machine control system comprises a power supply control system and a pressure control system. The power supply control system comprises a main drive system, a mandrel control system and a swing control system; the pressure control system comprises a feeding control system, a swing mechanism transmission system, an end face compaction control system and an oil stone pressure control system; a hydraulic control system comprises an inner ring centering compaction and center cooling control system, a workpiece cooling control system and a cleaning control system. The superfinishing machine control system can adapt to different machining environments and can be applied to superfinishing of an inner ring and an outer ring of a bearing simultaneously, the adaptability to different machining objects is high, adjustment of technological movement is convenient and precise, the reliability is high, and high-precision and high-quality superfinishing can be achieved by coordinating the functions of all parts.

Description

technical field [0001] The invention relates to a super precision machine control system. 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 pre...

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
