Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Some workpiece shapes allow burrs, chips, or cleaning liquid to remain easily in their internal recesses, making them difficult to remove with existing high-pressure cleaning devices.
Innovation Solution
A cleaning tool attachment with a housing, rotatable shafts, and a rotation axis conversion gear mechanism that synchronizes the rotation of multiple cleaning tools to efficiently remove foreign matter and cleaning liquid from workpieces by changing the rotation axis direction and ensuring synchronous phase angles, allowing simultaneous cleaning of multiple workpieces or areas.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a single rotational nozzle is used for high-pressure cleaning, then the cleaning device can operate with a simple structure, but it cannot effectively remove foreign matter from internal recesses of workpieces
Solution Approach 1:
The patent combines multiple cleaning tools (rotational nozzles, deburring tools, polishing tools) onto a single turret, allowing simultaneous or sequential operation of multiple cleaning functions on different workpieces or different areas of the same workpiece, thereby achieving effective cleaning of internal recesses while maintaining operational efficiency
Solution Approach 2:
The patent introduces a second shaft with axial direction different from the first shaft, creating a multi-dimensional cleaning approach. This allows cleaning tools to approach workpieces from multiple angles and directions, effectively removing foreign matter from internal recesses that cannot be accessed by a single-direction nozzle
2Productivity
If multiple cleaning tools are mounted on a turret to clean multiple workpieces, then cleaning productivity increases, but the tools cannot rotate synchronously to maintain proper phase angles
Solution Approach 1:
The patent introduces a synchronous rotation mechanism that acts as an intermediary between the first shaft and the tool mounting shafts. This mechanism transmits rotational motion while maintaining fixed phase relationships, ensuring that multiple cleaning tools rotate in synchronization at the same rotational speed and with predetermined phase angles, thereby enabling coordinated cleaning of multiple workpieces
Solution Approach 2:
The turret structure provides a universal mounting platform that can accommodate various types of cleaning tools (rotational nozzles, deburring tools, polishing tools) on different shafts. The synchronous rotation mechanism ensures that regardless of the tool types or their mounting positions, all tools can operate simultaneously with proper phase relationships, making the system versatile and adaptable to different cleaning requirements
