Nested Tool Magazine for Machining Center Capacity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing disk changers for processing tools face limitations in increasing tool capacity due to rigidity and positioning accuracy constraints, leading to the need for more complex and expensive chain changers to accommodate additional tools.
Innovation Solution
A magazine design with a first and second receiving device, where the second perimeter is smaller and nested within the first, allowing for space-efficient tool arrangement without enlarging the plate circumference, enabling additional tool storage without the need for a chain changer.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If the plate circumference is increased to accommodate more tools, then the tool capacity is improved, but the rigidity and positioning accuracy of the drive deteriorate
Solution Approach 1:
The patent applies nesting by placing a second receiving device with its own circumference inside the area bounded by the first circumference. This allows the magazine to hold more tools (increasing capacity) without enlarging the outer plate dimensions, thereby maintaining the rigidity and positioning accuracy of the drive system.
Solution Approach 2:
The patent transitions from a single-planar arrangement of tool holders to a multi-level configuration where the second receiving device is positioned within the radial space of the first. This dimensional reorganization increases tool capacity while keeping the plate diameter constant, avoiding the positioning accuracy issues that would arise from enlarging the plate.
2Quantity of substance
If the number of tool holders is increased to accommodate more tools, then the tool capacity is improved, but the device complexity increases
Solution Approach 1:
By nesting the second receiving device within the radial space of the first receiving device, the patent increases tool capacity while maintaining a relatively simple single-plate structure. This avoids the need for complex multi-plate or chain-based systems, thereby limiting the increase in device complexity.
3Quantity of substance
If a chain changer is used to accommodate more tools, then the tool capacity is improved, but the device complexity and cost increase significantly
Solution Approach 1:
The nested receiving devices on a single plate provide an alternative to chain changers, achieving increased tool capacity through spatial optimization rather than through complex mechanical systems. This maintains simplicity and reduces cost while still accommodating more tools.
