Multi-Tool Part Cleaning Machine for Single-Station Tool Change
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing part cleaning machines require multiple stations for different cleaning operations, necessitating part movement between stations, which is inefficient and increases processing time.
Innovation Solution
A part cleaning machine with a cradle and chuck system that allows for the selection and positioning of multiple tools on a single machine, enabling various cleaning operations without part movement, using a cradle drive system for X-axis movement and chuck drive system for Y and Z-axis movement, along with a locking mechanism for tool attachment and release.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple cleaning stations are used for different cleaning operations, then each cleaning operation can be performed with a specialized tool, but the part must be moved between stations which increases processing time and reduces productivity
Solution Approach 1:
The patent combines multiple cleaning stations into a single integrated machine that can perform multiple cleaning operations (deburring, washing, flushing, drying) on one part without requiring the part to be moved between separate stations. The machine includes multiple nozzles, brushes, and other cleaning tools that can be positioned around the part simultaneously.
Solution Approach 2:
The cleaning machine is designed as a universal device capable of performing multiple different cleaning operations using various interchangeable tools and nozzles. A single machine replaces multiple specialized stations, with each tool being adaptable to different cleaning requirements through the positioning system.
2Adaptability or versatility
If multiple cleaning stations are used for different cleaning operations, then each operation can be optimized with specific tools, but the complexity of the overall system increases due to multiple stations and part handling
Solution Approach 1:
The patent merges multiple cleaning stations into one integrated system, reducing the overall system complexity by eliminating the need for separate stations and the associated part handling mechanisms. All cleaning operations are performed within a single machine envelope.
Solution Approach 2:
The patent uses a multi-axis positioning system that moves nozzles and tools in three-dimensional space (X, Y, Z axes) to reach different parts of the workpiece. This dimensional approach allows multiple cleaning operations to be performed from a single stationary machine position rather than requiring multiple linear stations.
3Ease of manufacture
If the part is moved between stations for different cleaning operations, then each station can be simplified with a single tool, but the processing time increases and operational efficiency decreases
Solution Approach 1:
The positioning system pre-positions multiple nozzles and cleaning tools in optimal locations around the workpiece before cleaning operations begin. This preliminary arrangement of tools eliminates the need to move the part between stations during the cleaning process, reducing processing time while maintaining operational simplicity.
Solution Approach 2:
The patent employs dynamic positioning systems that can rapidly adjust the positions of nozzles and tools during the cleaning process. This dynamic capability allows the system to optimize tool positions for each cleaning operation without requiring physical movement of the part between stationary stations.

AI summary
A part cleaning machine includes a cradle moveable along an X axis, and rotatable about a first cradle axis. A part holder is attached to the cradle, and is rotatable about a second cradle axis. A chuck holder is moveable on a tool positioning plane that is perpendicular to the X axis. A tool chuck is attached to and moveable with the chuck holder. A tool holder is moveable relative to the chuck holder along the X axis. A plurality of tools are relesably attached to the tool holder for selective attachment to the tool chuck. A machine controller is operable to control movement of the chuck holder, the tool chuck, and the tool holder to transfer a selected one of the tools between the tool chuck and the tool holder, and position an appropriate tool and the part in different positions for several different cleaning operations.
