A device and method for air-suspended abrasive pool finishing

Abstract

The invention discloses a device and method for air-suspension abrasive pool finishing and processing, belonging to the field of metal surface finishing and processing. The device is mainly composed of workpiece rotary feeding system, abrasive pool, wind feeding system and base. Each unit cooperates with each other to achieve efficient and comprehensive finishing of the workpiece in the abrasive pool. This device can be applied to places where traditional finishing methods such as complex surfaces, special-shaped holes, and small gaps between workpieces are difficult to process. The device has strong adaptability, and can control the diameter of abrasive particles in the abrasive pool and the wind speed and pressure of the gas in the abrasive pool according to the finishing requirements of the workpiece to meet the processing requirements; at the same time, it can also control the flow of gas according to the finishing environment requirements of the workpiece itself. Type, temperature is adjusted. The device has the advantages of high finishing efficiency, simple operation, simple structure, safety and reliability, and the abrasive pool is also easy to clean and replace abrasives.

Description

technical field [0001] The invention relates to a finishing processing device and method of an air pressure suspended abrasive pool, and belongs to the field of finishing processing of metal surfaces. Background technique [0002] The surface quality of parts has an important influence on the service life and performance of parts. With the development of medical, aerospace, precision instrument, and mold manufacturing industries, people put forward higher and higher requirements for the surface quality of parts. Studies have shown that the microscopic morphology of the workpiece surface formed by traditional mechanical finishing methods (grinding, grinding, polishing, ultra-precision machining) is jagged, and the friction coefficient of this shape is large, which is easy to cause wear when rubbing, and the initial loss is large , low precision retention, can no longer meet the requirements of higher technical indicators. Therefore, the emerging finishing method is more and...

AI Technical Summary

Problems solved by technology

However, this technology is limited by the material of the workpiece, the size of the workpiece, and the removal amount of the surface of the workpiece material. Different position angles and surfaces with different curvatures have different removal rules.

At the same time, magnetic abrasives have the problems of high cost, short life and poor performance

Seriously restrict its development and application; the abrasive flow technology is the purpose of finishing by extruding semi-solid fluid abrasive through the surface of the workpiece to be processed. In the process of homogenization and finishing, there are serious over-throwing, inverted The circle problem greatly destroys the uniformity of the machined surface

These processing methods have different principles and have their own strengths, but each has its own limitations.
