AI Technical Summary

Technical Problem

Existing valve surface grinding equipment has poor functional integration. External surface grinding and internal hole grinding are separate and independent equipment, resulting in low processing efficiency. Furthermore, the internal hole grinding structure lacks versatility and is difficult to adapt to the processing needs of different hole diameters, depths, and irregularly shaped internal holes.

Method used

An integrated polishing assembly was designed, comprising detachable sandpaper and an adjustable arc support plate. Polishing parameters are adjusted in real time through a vision inspection module, achieving integrated polishing of external surfaces and internal holes to meet the needs of different hole diameters and depths.

Benefits of technology

It achieves integrated grinding of outer surface and inner hole, improves processing efficiency, adapts to the grinding needs of valves of various specifications and complex shapes, and enhances processing adaptability and precision.

Abstract

This invention relates to a surface treatment grinding equipment and method for metal valves, specifically in the field of intelligent valve grinding technology. The equipment includes a grinding table on which a valve workpiece to be ground is placed. A grinding assembly is mounted on the grinding table to grind the surface and bore walls of the valve workpiece. Through the operation of the grinding assembly, the external surface grinding and internal bore grinding structures are integrated into a single grinding head, solving the problem of redundant processes in existing separate equipment. Furthermore, the internal bore grinding structure can deform according to the visual inspection required for grinding the valve workpiece. The separation distance can be adjusted according to the internal bore size to adapt to different bore diameter requirements. The extension amount can be adjusted according to the internal bore grinding depth to adapt to different depth requirements. The deformation inclination can be adjusted to conform to the slopes and bevels of irregularly shaped internal bores, achieving contour grinding. This invention can meet the grinding needs of valves of various specifications and complex shapes.
