Drilling Device for Large Section Members with Swinging Arms
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods require separate machines for cutting and drilling large section members, necessitating the relocation of cut section members, which is inefficient and inconvenient.
Innovation Solution
A drilling device integrated into the cutting system with swinging support arms and sliding rollers, allowing for adjustable angles and precise control of drilling assemblies to drill side portions at vertex points without relocating the section members.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate machines are used for cutting and drilling section members, then each machine can be optimized for its specific function, but the workflow efficiency decreases due to the need to relocate cut section members to another machine
Solution Approach 1:
The patent combines the cutting machine and drilling machine into a single integrated device. The cutting unit with band saw blade and the drilling unit with movable arm and drill bit are merged into one machine structure, allowing both cutting and drilling operations to be performed on the same section member without relocation. This resolves the contradiction by maintaining functional optimization while eliminating the need for separate machines and improving workflow efficiency.
Solution Approach 2:
The integrated device performs multiple functions - both cutting section members to length and drilling side portions at vertex points. The machine is designed with universal capability to handle different operations on the same workpiece, eliminating the need for separate specialized machines and the associated relocation steps, thus improving productivity while maintaining functional capability.
2Adaptability or versatility
If a drilling device is added outside the cutting line, then drilling capability is provided, but the device complexity and space requirements increase
Solution Approach 1:
Instead of adding a separate drilling device outside the cutting line, the patent merges the drilling functionality directly into the cutting machine structure. The drilling unit is integrated with the cutting unit, sharing the same base and control system, which reduces overall device complexity while maintaining drilling capability.
Solution Approach 2:
The cutting machine is designed with multi-functionality to perform both cutting and drilling operations. This universal design eliminates the need for additional separate devices, reducing device complexity and space requirements while providing the necessary drilling capability for section member processing.
3Adaptability or versatility
If the drilling tool axis is held perpendicular to section member sides at various angles, then adaptability to different section member angles is improved, but the mechanism complexity increases
Solution Approach 1:
The patent employs dynamic, movable components - the movable arm with sliding rollers and the carriage system with threaded screw actuation - that can be positioned and angled to accommodate different section member orientations (90°, 60°, etc.). This dynamic positioning capability provides angle adaptability without requiring a completely fixed, complex mechanism for each specific angle.
Solution Approach 2:
The drilling device allows for parameter changes in positioning and orientation through the movable arm and carriage system. The threaded screw mechanisms enable precise adjustment of the drilling tool axis angle and position to match different section member configurations, providing adaptability through adjustable parameters rather than fixed complex mechanisms.
