Floating Carrier Device for Machine Tool Length Compensation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing machine tools face challenges in accurately compensating for deviations in tool lengths, which can lead to inefficiencies and inaccuracies in machining processes, particularly due to the need for complex sliding or rolling guides that require lubrication and are not easily adaptable to existing systems.
Innovation Solution
A machine tool design featuring a floating mounting system for carrier devices on holding devices, allowing for precise adjustment and fixation of tool positions along a displacement path without the need for lubrication, using a bearing device and adjusting device that can be pneumatically or hydraulically configured, enabling tool length compensation and retrofitting of existing machines.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If sliding or rolling guides are used to mount carrier devices, then the carrier devices can be adjusted and positioned, but the system requires lubrication, increases mechanical complexity, and is difficult to adapt to existing systems
Solution Approach 1:
The patent removes the complex sliding or rolling guide system from the mounting mechanism and replaces it with a simplified floating carrier device that relies on gravitational force and minimal mechanical elements, thereby eliminating the need for lubrication and reducing overall system complexity while maintaining positioning capability
Solution Approach 2:
The patent replaces the traditional mechanical sliding/rolling guide system with a floating mounting system that uses gravity-based positioning and minimal mechanical constraints, substituting complex mechanical guidance with a simpler system that achieves the same positioning function without requiring lubrication or complex components
2Measurement precision
If complex sliding or rolling guides are used, then positioning is possible, but the system is not easily adaptable to existing machine tools
Solution Approach 1:
The patent extracts the essential positioning function from the complex guide system and implements it through a simplified floating carrier device that can be independently mounted on existing machine tools without requiring integration of complex guiding mechanisms, thereby enhancing adaptability and retrofit capability
Solution Approach 2:
The floating carrier device is designed as a universal component that can be adapted to various existing machine tool configurations without requiring complex guide systems, making the solution broadly applicable and easily retrofittable across different machine tool platforms while maintaining positioning accuracy
3Device complexity
If floating mounting is used without adjustment mechanisms, then mechanical complexity is reduced, but the ability to compensate for tool length deviations is limited
Solution Approach 1:
The patent incorporates an adjustment mechanism that allows the floating carrier device to dynamically adapt its position along the displacement path, enabling active compensation for tool length deviations while preserving the overall simplicity and floating nature of the mounting system
Solution Approach 2:
The adjustment mechanism acts as an intermediary element between the floating carrier device and the holding device, providing the necessary adjustment capability for tool length compensation without compromising the simplicity and floating characteristics of the overall mounting system
