Floating Pipe Socket for Cutting Tool Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current cutting devices in automatic lathes face challenges with complex and time-consuming tool changes, particularly when replacing worn cutting tools, due to inaccuracies in repositioning and the risk of pipe socket jamming or falling during clamping and release.
Innovation Solution
The cutting device features a floating pipe socket with a bearing mount and annular elastomeric sealing elements, allowing radial and tilting movements, ensuring precise alignment and preventing damage by maintaining a secure fit between support and counter-support surfaces, and providing a separate receiving base for easy assembly and replacement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the pipe socket is rigidly fixed in the component, then the alignment precision is improved, but the risk of jamming during clamping and damage during release increases
Solution Approach 1:
The pipe socket is designed with floating mounting capability, allowing it to perform radial and tilting movements relative to the component. This dynamic adjustment enables the pipe socket to adapt to misalignments during clamping while maintaining precise alignment in the positioned state, thereby resolving the contradiction between alignment precision and jamming risk.
Solution Approach 2:
The patent introduces bearing means with elastically flexible material that allows the pipe socket to change its positional parameters (radial position and tilt angle) in response to clamping forces. This parameter change capability enables the system to accommodate alignment variations without jamming, while still achieving high alignment precision when positioned.
2Productivity
If the cutting tool is replaced frequently, then the productivity is improved, but the time for repositioning and alignment increases
Solution Approach 1:
The floating pipe socket with bearing means enables the cutting tool to self-align during the replacement process. The bearing elements automatically compensate for misalignments through elastic deformation, eliminating the need for manual repositioning and alignment operations. This self-service mechanism significantly reduces the time required for tool changes while maintaining high productivity.
3Reliability
If the pipe socket is mounted in a floating manner, then the risk of jamming is reduced, but the alignment precision deteriorates
Solution Approach 1:
The floating mounting is designed with bearing means that provide controlled movement capability. The pipe socket can dynamically adjust its position and orientation within the bearing elements, allowing it to compensate for misalignments while maintaining precise alignment when in the positioned state. This dynamic behavior resolves the contradiction between reduced jamming risk and maintained alignment precision.
Solution Approach 2:
The bearing elements made of elastically flexible material provide beforehand cushioning by absorbing misalignment forces before they can cause jamming. The elastic deformation of the bearing elements cushions the impact of positional variations, allowing the pipe socket to maintain precise alignment while preventing jamming during the clamping process.
