Machine Tool Spindle Heating Bypass for Rapid Temperature Cycling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing machine tool temperature control technologies are slow in adjusting temperatures due to the large volume of liquid in storage tanks, requiring significant time and power, and often necessitate modifications to the cooling device, which can be costly and prone to issues.
Innovation Solution
A supplementary mechanism that connects to the pipelines between the machine tool spindle and the cooling device, utilizing shortcut channels, electrical control valves, and a pump to rapidly direct coolant flow for heating or cooling, allowing for independent temperature control without modifying the original cooling device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If the liquid coolant is pumped into the accommodating cylinder of the machine tool to adjust the operating temperature, then the temperature control function is achieved, but the temperature adjustment speed is extremely slow
Solution Approach 1:
The patent divides the temperature control system into two independent parts: a large storage tank for coolant storage and a small accommodating cylinder for actual temperature adjustment. By segmenting the system, only the small volume of liquid in the accommodating cylinder needs to be heated or cooled rapidly, while the large storage tank maintains overall coolant supply. This resolves the contradiction by enabling fast temperature adjustment without requiring the entire large volume of coolant to be heated or cooled.
2Temperature
If a heating device or cooling device is used to adjust the temperature of the liquid in the storage tank, then the temperature control function is achieved, but considerable power is consumed and the adjustment speed is slow
Solution Approach 1:
The system segments the coolant volume into a large storage tank and a small accommodating cylinder. Heating or cooling devices only need to process the small volume in the accommodating cylinder, dramatically reducing power consumption while maintaining effective temperature control at the machine tool spindle.
Solution Approach 2:
The accommodating cylinder acts as an intermediary between the storage tank and the machine tool spindle. It receives a portion of the coolant from the storage tank, undergoes rapid heating or cooling, and then returns the temperature-adjusted coolant to the spindle. This intermediary mechanism enables efficient temperature control without requiring the entire storage tank to be heated or cooled.
3Temperature
If the original cooling device is modified to achieve effective temperature adjustment, then the temperature control function is improved, but the structure changes and increases the risk of problems and costs
Solution Approach 1:
The patent merges the temperature adjustment function into the existing cooling device structure by adding an accommodating cylinder that can be integrated into the coolant circulation system. Rather than modifying the core cooling device, the system combines the storage tank, accommodating cylinder, and existing cooling components into a unified system that maintains original structural integrity while adding temperature adjustment capability.
Solution Approach 2:
The accommodating cylinder serves multiple functions: it acts as a buffer for temperature-adjusted coolant, a chamber for heating or cooling operations, and a connection point between the storage tank and machine tool spindle. This multi-functional component enables temperature control without requiring extensive modifications to the original cooling device structure.

AI summary
A supplementary mechanism that provides a temperature rise and fall effect to a machine tool spindle is mainly used to connect to pipelines between a machine tool spindle and a cooling device. The present invention provides an additional heating function to the spindle of the machine tool that originally has a cooling device, and still retains its original cooling function. The supplementary mechanism can provide the effect of raising and lowering the temperature. When cooling, the liquid provided by the cooling device is passed to directly cool the machine tool spindle. When raising the temperature, the flow path is switched, so that the liquid of the cooling device cannot flow to the machine tool spindle, and the liquid flowing out of the machine tool spindle forms an independent circulation channel, and the supplementary mechanism heats the liquid in the independent circulation channel, achieving the effect of rapid heating.
