A Noise Reduction Device in Honing Process of Long-stroke and Large-diameter Hydraulic Cylinder

Abstract

The invention provides a noise reduction device and a noise reduction method for long-stroke large-diameter hydraulic cylinder honing processing procedure. The noise reduction device is composed of an intelligent control system and an annular support device. During the first working operation of the honing processing, the intelligent control system collects audio signal generated in the honing processing process through a sound pick-up and records the time required by a single working operation; an audio frequency recognition algorithm module is used for recognizing the noise spike appearing time; a support position computing module is used for computing position needing to reduce vibration and noise and add the support point. The noise amplitude-displacement diagram is displayed in a human-computer interaction unit of the intelligent control system and the position for adding support point in a numerical value manner. The number of the support point can be set by the operator through the human-computer interaction unit of the intelligent control system. During the honing processing period, the vibration and noise can be reduced in the honing processing process by moving or adding the annular support device to the position point given by the intelligent control system.

Description

technical field [0001] The invention relates to the field of honing processing, in particular to a noise reduction device in the honing processing of long-stroke and large-diameter hydraulic cylinder barrels. Background technique [0002] Honing is a traditional inner hole finishing technology. The so-called honing refers to a process in which the honing head with the honing rod rotates while reciprocating, and the honing rod is pressed against the honed surface of the workpiece with a certain pressure, thereby correcting the size, shape and surface roughness of the workpiece. The method is a semi-finishing and finishing process that can quickly and reliably remove a certain allowance and improve the surface roughness level. With the development of many high-tech products, the types of machining materials are increasing day by day, and the processing difficulty is increasing. The corresponding processing technology is given higher and higher requirements, especially in the ...

AI Technical Summary

Problems solved by technology

However, in the honing process of the inner hole of the hydraulic cylinder, especially the honing process of the long-stroke and large-diameter hydraulic cylinder, it is accompanied by a lot of noise, even a sharp whistle, causing serious noise pollution, disturbing the people, and serious Affect the physical and mental health of processing workers

In addition, most of the traditional workpiece auxiliary support devices are only for simply improving the rigidity of the workpiece during processing, and there are no public reports for purposeful vibration and noise reduction.
