Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing quick-stop devices (QSDs) for twist drills are not suitable for BTA horizontal drilling, as they require high processing accuracy and cannot effectively extract chip roots in deep hole drilling processes.
Innovation Solution
A BTA drilling quick-stop device with a horizontal structure, featuring a base with a hollow cavity, a movable fixture, a stopper, an elastic element, and a screw clamping mechanism, which allows for easy operation and low accuracy requirements, enabling rapid separation of the drill bit from the workpiece while maintaining a closed environment for deep hole processing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If existing QSDs for twist drills are used in BTA horizontal drilling, then the device structure can be simplified, but the processing accuracy requirements become too high and chip root extraction effectiveness deteriorates
Solution Approach 1:
The patent inverts the conventional vertical drilling QSD design by creating a horizontal drilling configuration. The fixture, stopper, and elastic element are arranged horizontally to match BTA drilling orientation, allowing chip root extraction without requiring high processing accuracy while maintaining structural simplicity
Solution Approach 2:
The patent changes the operational parameters by adjusting the fixture movement distance and stopper positioning to suit horizontal BTA drilling. The elastic element pre-compression distance is optimized to achieve sufficient separation speed without requiring precision machining, thereby resolving the contradiction between device simplicity and accuracy requirements
2Device complexity
If existing QSDs for twist drills are used in BTA horizontal drilling, then the device structure can be simplified, but the chip root extraction effectiveness deteriorates
Solution Approach 1:
The patent introduces dynamic movement of the fixture along the drill rod axis. The elastic element provides dynamic force to rapidly move the fixture and workpiece away from the drill bit, achieving effective chip root extraction in horizontal BTA drilling while keeping the overall device structure simple
Solution Approach 2:
The stopper is pre-positioned at a specific distance from the drill bit before drilling begins. This preliminary positioning ensures that when the drilling stops, the workpiece is already at the optimal location for chip root extraction, improving effectiveness without complicating the device structure
3Adaptability or versatility
If a horizontal structure is adopted for BTA drilling QSD, then the adaptability to BTA drilling is improved, but the device complexity increases
Solution Approach 1:
The horizontal QSD design serves multiple functions: it provides workpiece clamping, enables rapid stopping, achieves chip root extraction, and maintains compatibility with BTA drilling's closed environment requirements. This multi-functionality in a unified horizontal structure improves adaptability while avoiding excessive complexity through functional integration
