Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional boring machines cannot precisely machine a surface perpendicular to the axis of a boring hole due to sleeve deflection caused by gravity, resulting in an inaccurate cutting trajectory.
Innovation Solution
Incorporation of a deflection-compensating wedge plate between the sleeve and the rotatable face plate, which compensates for the sleeve deflection by adjusting the angle of the wedge plate based on the expected deflection, ensuring the face plate remains perpendicular to the boring hole axis.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the sleeve is supported in a cantilevered manner, then the device complexity is reduced, but the manufacturing precision deteriorates due to sleeve deflection under gravity
Solution Approach 1:
The wedge plate is pre-installed with an inclination angle that anticipates and counteracts the sleeve deflection caused by gravity. This preliminary anti-action compensates for the expected deformation, ensuring the face plate remains perpendicular to the boring hole axis during machining operations.
Solution Approach 2:
The inclination angle of the wedge plate is specifically designed based on the expected deflection amount. By changing the geometric parameter (inclination angle) of the wedge plate, the system compensates for the sleeve deflection and maintains machining precision without increasing structural complexity.
2Adaptability or versatility
If the sleeve length is increased to reach large-sized work, then the adaptability improves, but the manufacturing precision deteriorates due to increased deflection
Solution Approach 1:
The wedge plate compensation mechanism is designed to counteract the deflection that increases with sleeve length. By pre-calculating and compensating for the expected deflection based on sleeve length and gravity, the system maintains machining precision even when processing large-sized workpieces.
Solution Approach 2:
The inclination angle of the wedge plate can be adjusted or designed according to the specific sleeve length and expected deflection. This parameter change allows the system to adapt to different work sizes while maintaining perpendicularity of the machined surface.
