AI Technical Summary

Technical Problem

Existing CNC machine tool cleaning devices cannot prevent cross-contamination between tools, and the amount of cleaning fluid used is uncontrollable, resulting in high operating costs and a large amount of wastewater generated.

Method used

Design a cleaning device that includes a base, a bottom cleaning shell, and a top cleaning shell. The device cleans the blades separately through a closed structure and uses mechanical valves to control the spraying and shutting off of the cleaning fluid, allowing for flexible control of cleaning time and fluid volume.

Benefits of technology

It enables independent cleaning between tools, avoiding contamination, reducing the amount of cleaning fluid used and the amount of wastewater generated, and reducing operating costs.

Abstract

This utility model discloses a cleaning device for CNC machine tool cutting tools, belonging to the field of cutting tool maintenance technology. It includes a base with an insertion slot for inserting the cutting tool body in the center of the top. A cleaning bottom shell is fixedly installed around the top of the base, and a pushing ring is fixedly installed on the top of the cleaning bottom shell via a mounting bracket. It also includes a cleaning top shell. This utility model, through the combined use of the base, cleaning bottom shell, and cleaning top shell, has a simple structure and is convenient and practical. It allows the cutting tool body to be cleaned individually in a relatively enclosed environment, avoiding cross-contamination between cutting tools. Pressing down on the cleaning top shell sprays cleaning fluid onto the cutting tool body, and releasing it automatically closes the shell, allowing operators to control the rinsing time based on the degree of dirt on the tool surface, thereby controlling the amount of cleaning fluid used, reducing operating costs, and generating less wastewater.
