Description

A fixture for grinding and polishing bent pipe parts with different curvatures by solid-liquid two-phase flow

technical field

The invention relates to a fixture for grinding and polishing bent pipe parts with different curvatures by solid-liquid two-phase flow.

Background technique

With the rapid development of the economy, the application of precision parts in my country has become more and more extensive, and the abrasive flow processing technology has been derived. For the polishing or deburring of some complex parts, it is difficult for traditional processing methods to improve their finish. For example, manual polishing is used for polishing, so it is difficult to play a role in some inner holes or small cracks, and some parts cannot use traditional methods at all. Abrasive flow processing technology is produced for such problems. .

Abrasive flow machining technology is a high-efficiency and precise finishing method for complex curved surfaces. It uses abrasive flow media to flow through the surface of the workpiece under pressure to produce abrasive removal and control the material removal of the workpiece. rate to reduce the waviness and roughness of the surface of the workpiece to achieve the effect of precision machining. Abrasive flow machining technology is often used in complex curved surfaces that require manual finishing in complex processes, rounded corners or shapes that are difficult to process, and parts that are difficult to process by other methods.

However, before using abrasive flow machining technology to finish the workpiece, it is first necessary to design a special fixture for the workpiece, and different fixtures are required for the same type of workpiece with different shapes, which will consume manpower and material resources. Increase cost, cause inconvenience.
