Rotating Table Cleaning Through-Holes for Underside Chip Removal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional cleaning devices and machine tools face inefficiencies in removing chips from workpieces and jigs after cutting, as cutting fluid sprayed from nozzles often fails to effectively reach and clean the chips adhering to the underside of the workpiece and jig.
Innovation Solution
A cleaning device integrated into a rotating table with through holes and a container unit that stores cleaning fluid, utilizing centrifugal force to spray the fluid through holes facing the workpiece or jig, efficiently cleaning off chips by redirecting the cutting fluid used during cutting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If cleaning fluid is sprayed from a nozzle to clean chips from workpiece and jig, then cleaning function is provided, but cleaning efficiency is insufficient for chips on underside of workpiece and jig
Solution Approach 1:
Instead of spraying cleaning fluid from above the workpiece (conventional approach), the invention inverts the approach by rotating the table to spray cleaning fluid from underneath the workpiece and jig. This allows the cleaning fluid to reach chips on the underside that were previously inaccessible, significantly improving cleaning coverage and efficiency.
Solution Approach 2:
The invention introduces dynamic rotation of the table to change the orientation and position of the cleaning fluid spray. By rotating the table, the cleaning fluid can be directed at different surfaces of the workpiece and jig, enabling comprehensive cleaning of all areas including undersides, rather than relying on a fixed spray direction.
2Productivity
If cutting fluid is sprayed during cutting operation, then cutting process is performed, but cleaning function after cutting is insufficient
Solution Approach 1:
The invention makes the cleaning fluid spray system multi-functional by enabling it to serve both cutting and cleaning purposes. The same cleaning fluid nozzle is used during cutting to cool and lubricate the workpiece, and then the table is rotated to use the same fluid for cleaning chips after cutting, eliminating the need for separate systems and improving overall efficiency.
Solution Approach 2:
The invention employs periodic action by alternating between cutting mode and cleaning mode. During cutting, the table remains in one position for chip removal; after cutting, the table rotates to a different position for cleaning. This periodic switching between functions allows the system to efficiently perform both cutting and cleaning operations using the same fluid delivery mechanism.
3Productivity
If cleaning fluid is sprayed from fixed position, then simple structure is maintained, but cleaning coverage of workpiece and jig is limited
Solution Approach 1:
The invention merges the cleaning function with the existing table structure of the machine tool. Rather than adding a separate complex cleaning mechanism, the invention utilizes the table's rotational capability to achieve cleaning coverage, integrating the cleaning function into the already-present table structure and minimizing additional complexity.
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 solution enables efficient removal of chips from both the workpiece and jig by utilizing centrifugal force to spray stored cutting fluid through strategically positioned holes, improving cleaning efficiency and reducing fluid application on the table surface.
Implementation Method 1
compressing the storage space by a centrifugal force created by rotation of the table about a horizontal axis line
