Rotating Washing Nozzle for Wider Machine Tool Coverage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing machine tool washing systems with fixed nozzles face limitations in washing a wide range effectively due to constraints on increasing jet angles and nozzle numbers, resulting in dead spaces that are not sprayed with washing fluid.
Innovation Solution
A washing nozzle system with a base portion and a rotary member that allows fluid to be jetted from a nozzle port, causing the rotary member to rotate and hit the surface, effectively increasing the washing range with a reduced number of nozzles, including configurations on the upper and side surfaces of the machine tool and the workpiece table.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If the jet angle of fluid from the nozzle is increased or the number of nozzles is increased to decrease intervals, then the washing range is expanded, but the device complexity and pump size increase
Solution Approach 1:
The nozzle is designed to rotate about an axis parallel to the mounting surface, transforming from a static fixed nozzle to a dynamic rotating nozzle. This rotation allows a single nozzle to cover a wider washing range by dynamically changing the spray direction, eliminating the need for multiple fixed nozzles and reducing device complexity
Solution Approach 2:
The invention introduces rotational motion as a new dimension of movement for the nozzle. Instead of only adjusting the jet angle within a fixed plane, the nozzle can rotate to spray in multiple directions around the workpiece, effectively expanding the washing range from two-dimensional coverage to three-dimensional coverage with a single nozzle
2Area of stationary object
If the jet angle of fluid from the nozzle is increased or the number of nozzles is increased, then the washing range is expanded, but the pump size and energy consumption increase
Solution Approach 1:
The rotating nozzle design allows a single nozzle to dynamically cover a wider area, reducing the need for multiple nozzles and the pump capacity required to supply them. The rotation mechanism distributes the washing task over time and space, enabling a smaller pump to achieve the same overall washing effect that would otherwise require a larger pump supplying multiple simultaneous nozzles
Solution Approach 2:
The invention merges the function of multiple fixed nozzles into a single rotating nozzle. By combining the spray functions of what would otherwise be multiple nozzles into one rotating component, the system reduces the total number of nozzles and the pump size required, thereby reducing energy consumption while maintaining or expanding the washing range
3Device complexity
If a fixed nozzle is used to wash a wide range, then the structure is simple, but dead spaces remain where washing fluid is not sprayed
Solution Approach 1:
The nozzle rotates about an axis parallel to the mounting surface, dynamically changing the spray direction to cover areas that would otherwise be dead spaces. This rotational movement ensures that fluid is sprayed across the entire workpiece surface, eliminating uncovered areas while maintaining a relatively simple single-nozzle structure
Solution Approach 2:
By introducing rotation as a new degree of freedom, the system transitions from fixed-plane spraying to multi-directional spraying. This dimensional change allows the nozzle to reach areas around the workpiece that would be inaccessible to a fixed nozzle, eliminating dead spaces without requiring multiple nozzles positioned in different locations

Function Achieved in This Case
This configuration allows for a wide range of the machine tool to be washed using fewer nozzles, reducing the size and energy consumption of the pump required for fluid supply, achieving efficient and energy-saving washing.
Implementation Method 1
the jet port is formed so that fluid jetted from the jet port of the rotary member hits the surface on which the base portion is mounted and the jet of the fluid causes the rotary member to rotate about the parallel axis
