Axial Workpiece Cleaning Turntable for Fast Cleaning and Drying
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional cleaning apparatuses face difficulties in effectively cleaning and drying axially extending workpieces, such as crankshafts, due to challenges in positioning and retracting nozzles during rotation, which hinders efficient cleaning of end and shaft portions.
Innovation Solution
A cleaning apparatus with a 180-degree turntable and clamping devices on both sides of the cleaning chamber, allowing for axial clamping and rotation of workpieces, enabling simultaneous cleaning and drying of end and shaft portions using a cleaning station and drying station with lift tables and clamp shafts, facilitating efficient cleaning and drying processes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the cleaning table is rotated to clean the shaft portion, then the cleaning coverage is improved, but the nozzle must be retracted which increases the cycle time
Solution Approach 1:
The cleaning table is designed to rotate dynamically during the cleaning process, allowing the workpiece to be positioned at different angles relative to the stationary nozzle. This dynamic rotation enables the nozzle to clean both the end portion and shaft portion without needing to retract, thereby maintaining continuous cleaning action and reducing cycle time while improving overall cleaning coverage.
2Productivity
If the air blowing nozzle is positioned close to the workpiece for effective drying, then the drying efficiency is improved, but the nozzle cannot be brought close when the cleaning table is rotated
Solution Approach 1:
The air blowing nozzle is positioned to remain stationary while the cleaning table rotates to bring different portions of the workpiece into the drying zone. The nozzle is strategically positioned to cover the shaft portion during rotation, and the workpiece is dried during specific phases of the rotation cycle, eliminating the need for complex nozzle positioning mechanisms while maintaining effective drying.
3Stability of the object's composition
If the workpiece is clamped on the cleaning table for rotation, then the workpiece stability is improved, but the clamping mechanism adds device complexity
Solution Approach 1:
The clamping function is merged with the existing cleaning table structure. The cleaning table itself incorporates clamping mechanisms that are integrated into its design, allowing the workpiece to be securely held for rotation without requiring separate, complex external clamping devices. This integration maintains workpiece stability while simplifying the overall device structure.
