Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Force
If a piston presses the center disk to maintain contact, then the spindle body can be tilted, but the moment load makes it difficult to reduce the required load for tilting
Solution Approach 1:
The invention employs a spherical contact surface between the piston and the center disk, replacing traditional flat or curved piston designs. This spherical geometry allows the piston to maintain point contact with the center disk during tilting motion, reducing the moment arm and consequently the moment load required to achieve tilting while maintaining reliable contact under varying loads
2Ease of operation
If the spindle body is tilted against moment load, then deburring function is achieved, but the piston movement becomes difficult
Solution Approach 1:
The spherical contact surface between the piston and center disk creates a pivot point that minimizes the moment arm during tilting operation. This geometric configuration reduces the moment load acting on the piston, making piston movement easier while still achieving the necessary tilting function for effective deburring
3Manufacturing precision
If traditional piston design is used, then结构简单(simple structure) is maintained, but tilting precision and seal wear are problematic
Solution Approach 1:
The spherical contact surface provides a precise pivot point for tilting motion, enabling accurate angular positioning of the spindle body. This geometric feature inherently guides the tilting motion along a defined arc, improving tilting precision without requiring complex control mechanisms or additional guiding elements
Solution Approach 2:
The invention incorporates a spring element that pre-compresses against the piston, maintaining constant contact pressure between the spherical piston surface and the center disk. This pre-loaded spring ensures reliable contact during tilting operation, preventing impact and wear on the seal while accommodating variations in loading conditions
