AI Technical Summary

Technical Problem

In the existing technology, water spray pipes are prone to leaving defects such as burrs and oxide scale during the production and processing, resulting in uneven polishing, which affects the performance and service life of the cleaning equipment. In addition, traditional manual polishing is inefficient and difficult to adapt to complex structures.

Method used

A device for grinding the inner and outer walls of water spray pipes in cleaning equipment has been designed. It adopts a combination structure of arc plate and grinding belt, which can flexibly adjust the angle and tension to adapt to pipes of different diameters and degrees of curvature. It also prevents overheating through heat-conducting wheel and cooling system, and achieves integrated grinding of inner and outer walls.

Benefits of technology

It improves the grinding quality and automation level of water spray pipe fittings, extends the service life of vulnerable parts of the equipment, simplifies the production process, and enhances grinding efficiency and equipment versatility.

Abstract

This invention relates to the technical field of water spray pipe fitting grinding devices, specifically a device for grinding the inside and outside of water spray pipe fittings for cleaning equipment. It includes a base, a slide table slidably mounted on the upper end of the base, a turntable rotatably mounted on the upper end of the slide table, a support frame fixedly mounted on the upper end of the turntable, an arc-shaped plate rotatably mounted on the upper end of the support frame, and support wheels rotatably mounted on both the upper and lower ends of the inner side of the arc-shaped plate. A grinding belt is sleeved between the two support wheels. A heat-conducting wheel is rotatably mounted on the inner end of the arc-shaped plate, and an adjustment device is provided inside the heat-conducting wheel. The arc-shaped plate can flexibly extend into the water spray pipe assembly and its angle can be flexibly adjusted to facilitate insertion into pipes of various diameters and degrees of curvature. Furthermore, the shape of the arc-shaped plate allows the grinding belt to better conform to the curved surface of the pipe's inner wall, ensuring sufficient contact with the inner wall surface during grinding, thereby improving the grinding effect.
