Machine Tool Partition and Drainage Layout for Clean Tool Changes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
During machining, cutting fluid splashes into the machining chamber and contaminates or damages the tool storage chamber when the shutter is opened to change tools, as it can flow along the wall surfaces into the tool storage chamber.
Innovation Solution
A machine tool design with a U-shaped receiving member and inclined wall members to direct and collect cutting fluid, combined with a shutter drive device and a nozzle for efficient fluid management, preventing fluid entry into the tool storage chamber.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the shutter is opened to change tools, then tool exchange can be performed, but cutting fluid and chips may flow along the wall surface into the tool storage chamber causing contamination or damage
Solution Approach 1:
A receiving member with a U-shaped inner surface is introduced as an intermediary structure between the machining chamber and tool storage chamber. This receiving member captures cutting fluid and chips that fall along the wall surface, preventing them from entering the tool storage chamber while allowing the shutter to remain open for tool exchange operations
Solution Approach 2:
The inclined wall member is designed to guide cutting fluid and chips toward the receiving member, converting the harmful flow of contaminants into a controlled path that directs them into the receiving member for collection, thereby protecting the tool storage chamber
2Object-affected harmful factors
If the shutter is positioned behind the partition wall to avoid cutting fluid, then cutting fluid entry is suppressed, but the shutter size is enlarged and requires spindle head movement
Solution Approach 1:
The receiving member serves as an intermediary protective structure that allows the shutter to be positioned at its optimal location in the partition wall without requiring enlargement. The receiving member intercepts contaminants before they can reach the tool storage chamber, eliminating the need to relocate or enlarge the shutter

Function Achieved in This Case
Effectively suppresses the entry of cutting fluid and chips into the tool storage chamber during tool changes, reducing contamination and potential device failures.
Implementation Method 1
receive the cutting fluid falling along the side wall member when the shutter is opened
Implementation Method 2
cutting fluid falling along the side wall member

AI summary
This machine tool is provided with: a partition that partitions a machining chamber and a tool storage chamber and that has an opening; a shutter; and a receiving member that is formed so as to receive cutting fluid. The partition includes a sidewall member that extends in the vertical direction and an inclined wall member inclined in such a manner so as to become lower from the sidewall member to the interior of the machining chamber. At least part of the opening is formed in the inclined wall member. The receiving member is positioned beneath the shutter, and in such a position so as to receive cutting fluid that drops down along the sidewall member when the shutter is opened.
