Lathe Tool Holder Segmented Cooling Channels
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional lathe tool holders are difficult to manufacture due to the need for drilling water passages and outlets directly within the tool holder, leading to increased production costs and reduced water pressure from single-tube pipes.
Innovation Solution
A tool holder design featuring a body with first and second water channel holes, a base with a water inlet and groove, and a sprayer with water spraying passages, allowing for easier manufacturing by defining channels on the surface rather than drilling within the holder, and enhancing water pressure through two-tube passages.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If water passages and outlets are drilled directly within the tool holder, then the cooling function is achieved, but the manufacturing difficulty increases and production cost rises
Solution Approach 1:
The tool holder is divided into an upper holder and a lower holder that can be separately manufactured. The water passages are formed in the lower holder through drilling from the bottom surface, while the upper holder is manufactured separately and then assembled. This segmentation allows each part to be produced independently with simpler processes, reducing overall manufacturing difficulty while maintaining the cooling function.
Solution Approach 2:
The water passages are designed as through-holes that pass through the lower holder, with sealing members nested within these passages. The upper holder is then positioned and fixed onto the lower holder, with the cutting tool inserted into the upper holder. This nested structure allows the water passages to extend through multiple components while maintaining sealed channels for coolant flow.
2Device complexity
If single-tube pipes are used for water outlets, then the structure is simple, but the water pressure is dispersed and cooling effectiveness decreases
Solution Approach 1:
The single water outlet tube is divided into multiple separate outlet tubes (first outlet tube and second outlet tube). Each tube receives water through separate passages in the lower holder, allowing the water flow to be distributed through multiple channels. This segmentation prevents pressure dispersion while maintaining relatively simple structural design.
Solution Approach 2:
The design utilizes hydraulic principles by creating multiple water passages and outlet tubes that work together to deliver pressurized coolant to the cutting tool. The through-holes in the lower holder act as fluid channels that maintain pressure by providing direct pathways for water flow from the bottom surface to the outlet tubes.
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 design simplifies manufacturing, reduces costs, and improves water pressure by concentrating the fluid's discharge, making the tool holder easier to produce and more efficient in cooling the lathe tool.
Implementation Method 1
each of the water spraying passages has one end located at the first end surface and connected to the two diverted water channels, and another end located at the second end surface
Implementation Method 2
cutting fluid is injected into the inlet 17, and flows out of the first and second outlets 15, 16, and finally the cutting fluid flowing from the first outlet 15 will flush and cool the cutting tool 13
Implementation Method 3
the cutting fluid flowing from the second outlet 16 flows into the fluid channel 21 via the first end 201, and finally flows out of the second end 202 to further cool the cutting tool 13
