Drilling Machine Laser Alignment With Stable Multi-Angle Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional laser alignment systems for drilling machines lack stability and precision in adjusting the laser beam, making them troublesome to use effectively in aligning drilling positions on workpieces.
Innovation Solution
The proposed laser alignment system includes two first fixers, two lamp holders, and two second fixers with a design that enhances the contacting area between the peripheral knob and arcuate portions, allowing for secure adjustment of the laser beam, featuring adjustable screws and resilient elements to adjust the swing and rotation angles of the laser lamp, thereby improving stability and precision.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a conventional drilling machine uses operator's eyes to align drilling position, then the alignment process is simple, but the drilling position accuracy deteriorates causing offset
Solution Approach 1:
The patent introduces a laser alignment system as an intermediary tool between the operator and the workpiece. The laser projects a visible alignment line that serves as a mediator, allowing the operator to accurately position the drill head without direct visual estimation, thus improving drilling position accuracy while keeping the operation simple
2Ease of manufacture
If a laser alignment system uses a simple mounting structure, then the manufacture cost is reduced, but the laser beam adjustment stability deteriorates
Solution Approach 1:
The laser alignment system is divided into separate modular components: a base portion that mounts to the drill press, and a laser assembly portion that can be independently adjusted. This segmentation allows each component to be manufactured separately with standard parts, reducing overall manufacture cost while enabling stable, precise adjustment of the laser beam through the modular connection
3Device complexity
If a laser alignment system uses minimal fixing components, then the device complexity is reduced, but the laser adjustment precision deteriorates
Solution Approach 1:
The laser assembly portion incorporates adjustable elements that allow dynamic positioning and securing of the laser at various angles and positions. This dynamic adjustment capability enables precise laser beam alignment while using a relatively simple fixing structure with basic adjustment mechanisms rather than complex rigid mounting systems
