Solution Overview
Problem
Existing section member drilling and milling machines require substantial effort and time for horizontal movement due to their large weight, and the tools lack precision for vertical operations, making it difficult to engrave symbols or markings on the section members.
Innovation Solution
A section member drilling or milling machine with a support system that includes precision vertical and horizontal guides, driven by motors connected to numerical control units, allowing controlled high-speed movement in both vertical and horizontal planes, enabling precise machining operations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the support assembly has large weight to ensure stability, then the drilling or milling unit can be controllably driven along guides, but the sliding movement on horizontal guides requires substantial effort and large time
Solution Approach 1:
The support assembly is divided into a movable support (4) and a stationary machine bed (2). The movable support carries the drilling or milling unit and can be selectively positioned along the longitudinal guide, while the machine bed remains fixed. This segmentation allows the system to achieve both mobility for positioning and stability for precision operations.
2Reliability
If the support assembly has large weight to ensure stability, then the drilling or milling unit can be controllably driven along guides, but substantial effort is required for sliding movement
Solution Approach 1:
The support assembly is divided into a movable support (4) and a stationary machine bed (2). The movable support carries the drilling or milling unit and can be selectively positioned along the longitudinal guide, while the machine bed remains fixed. This segmentation allows the system to achieve both mobility for positioning and stability for precision operations.
3Reliability
If the support assembly has large weight, then stability is improved, but drilling or milling tool precision is not always satisfactory
Solution Approach 1:
The support assembly is divided into a movable support (4) and a stationary machine bed (2). The movable support carries the drilling or milling unit and can be selectively positioned along the longitudinal guide, while the machine bed remains fixed. This segmentation allows the system to achieve both mobility for positioning and stability for precision operations.
Solution Approach 2:
The system uses precision vertical guides (8) and precision horizontal guides (10) at critical locations to ensure high positioning accuracy. The movable support (4) is equipped with these precision guides to control its movement, while the machine bed (2) provides a stable base. This local application of high-precision components ensures accurate drilling or milling operations.
4Ease of manufacture
If the machine uses conventional guides and support structure, then basic drilling function is achieved, but it is not possible to engrave symbols or markings on the section member body
Solution Approach 1:
The movable support (4) is designed to carry different tools or tool assemblies, allowing it to perform multiple functions including drilling, milling, and engraving operations. The precision positioning system with vertical guides (8) and horizontal guides (10) enables the tool to accurately position and execute various machining tasks on the section member.
