Pivoting Suction Hood for Machine Tool Dust Extraction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing suction hoods for machine tools with rotating tools, such as grinding or cutting tools, complicate and prolong the process of tool changes due to their design, making it difficult to remove and replace the tools efficiently.
Innovation Solution
A suction hood with a first side wall that can be reversibly pivoted between a closed and open position, allowing for easy tool access and attachment, featuring a hinge mechanism and recesses for accommodating the tool and machine tool components, facilitating tool change by enabling the hood to be opened and closed for tool exchange.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the suction hood is designed with a fixed closed structure to effectively collect dust, then dust collection efficiency is improved, but tool replacement becomes complicated and time-consuming
Solution Approach 1:
The suction hood incorporates a movable side wall that can pivot between a closed position for dust collection and an open position for tool access. This dynamic structure allows the hood to adapt its configuration based on operational needs, resolving the contradiction between maintaining a closed structure for dust collection and enabling easy tool replacement.
2Object-affected harmful factors
If the suction hood is designed with a fixed closed structure to contain dust, then dust containment is improved, but ease of operation for tool changes deteriorates
Solution Approach 1:
The suction hood is segmented into movable and fixed parts, with the side wall capable of pivoting independently. This segmentation allows the hood to maintain dust containment when closed while providing easy access for tool changes when opened, resolving the contradiction between dust containment and operational ease.
3Ease of operation
If the suction hood structure is simplified for easy tool access, then ease of operation is improved, but dust collection effectiveness deteriorates
Solution Approach 1:
The movable side wall design allows the suction hood to dynamically switch between open and closed states, providing easy tool access when opened while maintaining effective dust collection when closed, thus resolving the contradiction between operational ease and dust collection effectiveness.

AI summary
Extraction hood (1) for a machine tool (2) with a rotating tool (10), in particular a grinding or cutting tool, for collecting and discharging dust generated during the use of the machine tool (2), comprising a first side wall (11) with a first straight side edge (21), a second side wall (12) with a second straight side edge (22), and an extraction channel (13) connected to the first and second side walls (11, 12). The first side wall (11) is reversibly pivoted between a first position and a second position, wherein in the first position the extraction hood (1) is in a closed state, so that a nearly closed cavity is formed between the first side wall (11) and the second side wall (12) for receiving the tool (10), and wherein in the second position the extraction hood (1) is in an open state, so that the tool (10) can be removed from the machine tool (2).
