Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current numerical control machine tools face inefficiencies in machining thin plates due to the need to manually position and machine slender sheets in a horizontal position, leading to increased time and costs, poor precision from simultaneous machining with multiple spindles, and challenges in adapting to varying plate thicknesses and sizes, especially in the fashion and consumer electronics sectors where machines must be compact and lightweight.
Innovation Solution
A device with automatic adjustment capable of varying its opening to grip plates of different sizes, using a plurality of spindles for simultaneous machining on a vertical plane, decoupling the system to minimize vibrations and flexures, and allowing easy evacuation of machining residues, with independent spindle operation to maintain precision and efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a plurality of spindles is used for simultaneous machining of both sides, then productivity is improved, but manufacturing precision deteriorates due to vibrations and flexures
Solution Approach 1:
The patent implements independent numerical control for each spindle, allowing dynamic adjustment of machining parameters, speeds, and feeds for each spindle individually. This enables real-time optimization to minimize vibrations and flexures while maintaining simultaneous machining operations, thus resolving the contradiction between productivity improvement and precision maintenance
Solution Approach 2:
The patent divides the machining system into independently controlled segments (spindles), where each spindle can be controlled separately through independent numerical control. This segmentation allows each spindle to operate optimally without being constrained by the others, reducing相互 interference and vibrations while maintaining high productivity through simultaneous operation
2Ease of operation
If thin plates are machined in horizontal position, then ease of operation is improved, but productivity deteriorates due to need to overturn the piece for machining both sides
Solution Approach 1:
The patent transitions from horizontal to vertical machining position, utilizing the vertical dimension to position multiple spindles above and below the workpiece. This dimensional change enables simultaneous machining of both sides without requiring piece overturning, thus improving productivity while maintaining ease of loading through the vertical configuration
3Device complexity
If gripping system is made fixed, then device complexity is reduced, but adaptability deteriorates for plates of different sizes and thicknesses
Solution Approach 1:
The patent implements adjustable gripping means that can dynamically adapt to different plate thicknesses and sizes. The gripping system includes movable and adjustable components that can be positioned and configured according to the specific workpiece dimensions, providing both adaptability and maintaining reasonable device complexity through standardized adjustment mechanisms
4Ease of operation
If machining is done on horizontal plane, then ease of operation is improved, but object-generated harmful factors worsen due to chips affecting spindle effectiveness
Solution Approach 1:
The patent changes the machining plane from horizontal to vertical orientation. This dimensional change allows chips to fall away from the machining zone under gravity rather than accumulating on the horizontal surface, eliminating chip interference with spindle effectiveness while maintaining ease of operation through vertical loading and unloading mechanisms
