Expandable Machine Cover With Liquid-Cleaned Chip Groove
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional protective devices for machine tools fail to completely prevent the entry of small chips or powdered chips into the feed mechanism, leading to accumulation in grooves, which causes obstruction and potential deformation or breakage of movable cover pieces.
Innovation Solution
A protective device with a structural body featuring a groove with a top opening, a nozzle for ejecting a pressurized liquid into the groove, and a liquid supply source to wash away chips and coolant, preventing accumulation and ensuring smooth movement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If protective bodies are configured to expand and contract as a whole, then continuous protection is maintained during movement, but the structure becomes complex
Solution Approach 1:
The protective bodies are designed with dynamic expansion and contraction capabilities, allowing them to adapt their configuration during movement. This dynamic behavior maintains continuous protection coverage while using relatively simple connection structures between individual protective bodies
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The liquid flow in the groove effectively removes small chips and coolant, preventing accumulation and subsequent obstruction, thus maintaining the integrity and functionality of the protective bodies.
Implementation Method 1
a nozzle for ejecting a pressurized liquid into the groove

AI summary
The present invention includes a plurality of protective bodies (13, 14, 15) sequentially connected in a moving direction of a moving body and separating a movement path of the moving body from the outside. The protective body (15) at a first end is connected to a predetermined end (12a) of an area to be protected, and the protective body (13) at a second end is connected to the moving body. The plurality of protective bodies (13, 14, 15) are configured to be expanded and contracted as a whole by movement of the moving body. A structural body (35) having a groove (35a) having a top opening and forming a flow path is provided. The structural body (35) is arranged along the protective bodies (13, 14, 15) below the protective bodies (13, 14, 15) or arranged along the protective bodies (13, 14, 15) such that the lower ends of the protective bodies (13, 14, 15) are inserted in the groove (35a) through the top opening of the groove (35a). The groove body (35) is provided with a nozzle (38) ejecting a liquid into the groove (35a), and a pressurized liquid is supplied to the nozzle (38) from a liquid supply source (40).
