Telescopic Cover Structure for Cutting Fluid Discharge
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing telescopic covers for machine tools fail to effectively prevent cutting fluids and chips from falling onto linear motion mechanisms, leading to exposure and potential damage, and require complex collection chutes for fluid discharge.
Innovation Solution
A telescopic cover system with nested cover pieces featuring wipers for fluid removal and cutaway parts for fluid discharge, which prevents fluid from reaching the linear motion mechanisms and eliminates the need for collection chutes by directing discharge below the mechanisms.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If collection chutes are provided on end faces of covers to discharge chips, then chips can be discharged from overlapping portions, but the structure becomes complex and cutting fluids can still reach the linear motion mechanism
Solution Approach 1:
The cover is divided into multiple cover pieces arranged in a nested manner, with each cover piece having independent wiper parts and discharge parts. This segmentation allows each component to perform its function independently, simplifying the overall structure while maintaining effective chip and fluid discharge capabilities.
Solution Approach 2:
The harmful function of collection chutes is eliminated by extracting the discharge function directly into cutaway parts of the cover pieces. The harmful elements (cutting fluids and chips) are directed outward through these cutaway parts without requiring complex collection chutes, thus simplifying the structure.
2Reliability
If nested cover pieces are used to cover the linear motion mechanism, then the mechanism is protected, but cutting fluids can enter overlapping portions and reach the mechanism
Solution Approach 1:
Wiper parts are introduced as intermediary elements between the nested cover pieces. These wipers actively remove cutting fluids from the outer surfaces of inner cover pieces, preventing the fluids from entering the overlapping portions and reaching the linear motion mechanism.
Solution Approach 2:
The harmful cutting fluids are extracted from the overlapping portions through discharge parts formed by cutting away portions of the cover pieces. This allows fluids to be directed outward away from the mechanism rather than allowing them to accumulate and reach the protected components.
3Object-affected harmful factors
If wiper parts are added to wipe cutting fluids, then fluid removal is improved, but the cover structure becomes more complex
Solution Approach 1:
The wiper parts and discharge parts are merged into a single integrated cover piece structure. The wiper parts are formed as integral components of the cover pieces, and the cutaway discharge parts are directly formed in the same components, eliminating the need for separate parts and reducing overall structural complexity.

AI summary
A telescopic cover for covering a linear motion mechanism in which a movable part is driven in a horizontal direction. The telescopic cover includes a plurality of cover pieces arranged in a nested manner and supported in a movable manner in a driving direction of the movable part. Of two internally and externally adjoining cover pieces, an outer cover piece has a wiper for wiping an outer surface of an inner cover piece. The inner cover piece has a weir part standing upright from the outer surface thereof toward an inner surface of the outer cover piece at an edge of an area constantly overlapping the outer cover piece, and a cutaway part formed by cutting away at least a portion of the weir part or the area to communicate between an inside and an outside of the inner cover piece.
