Section Member Drilling Milling Machine Segmented Guide System

Solution Overview

Problem

Existing section member drilling and milling machines face challenges with heavy support assemblies that require substantial effort and time for horizontal movement, resulting in unsatisfactory precision and the inability to engrave symbols or markings due to inertia.

Innovation Solution

A section member drilling or milling machine with a machine bed and precision vertical guides, featuring a cantilever arm and driving motor to enable controlled high-speed movement in both vertical and horizontal planes, allowing for precise tool operation and engraving capabilities.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Manufacturing precision

If a heavy support assembly with large extension sliding guides is used, then the drilling and milling unit can be positioned along the section member, but the sliding movement requires substantial effort and time, and precision is not satisfactory

Engineering Contradiction:

Improvedrilling precisionVSAvoidsliding time

Core Design Contradiction:

Manufacturing precisionVSLoss of time

Solution Approach 1:

The support assembly is segmented into multiple independent components: a support structure with vertical guides, a platform with horizontal guides, and a carriage. Each segment can move independently on its own guides, allowing the system to achieve precise positioning without requiring the entire assembly to slide along long guides. This segmentation eliminates the need for substantial sliding effort and time while maintaining drilling precision.

Inventive Principle:

Principle #1Segmentation

2Manufacturing precision

If a heavy support assembly with large extension sliding guides is used, then the drilling and milling unit can be positioned along the section member, but the sliding movement requires substantial effort

Engineering Contradiction:

Improvedrilling precisionVSAvoidsliding effort

Core Design Contradiction:

Manufacturing precisionVSForce

Solution Approach 1:

The support assembly is segmented into multiple independent components: a support structure with vertical guides, a platform with horizontal guides, and a carriage. Each segment moves independently on its own guides, allowing the system to achieve precise positioning without requiring the entire assembly to slide along long guides. This segmentation eliminates the need for substantial sliding effort while maintaining drilling precision.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The system transitions from a static heavy support assembly to a dynamic multi-axis positioning system. The carriage can be rapidly positioned along the horizontal guides of the platform, and the drilling unit can move along the vertical guides of the support structure. This dynamic positioning capability reduces the force required compared to sliding the entire heavy assembly along long guides.

Inventive Principle:

Principle #15Dynamics

3Manufacturing precision

If a heavy support assembly with inertia is used, then the drilling and milling unit can be stabilized, but it is not possible to engrave symbols or markings due to inertia

Engineering Contradiction:

Improvepositioning accuracyVSAvoidengraving capability

Core Design Contradiction:

Manufacturing precisionVSAdaptability or versatility

Solution Approach 1:

The system transitions from a static heavy support assembly to a dynamic multi-axis positioning system. The carriage can be rapidly positioned along the horizontal guides of the platform, and the drilling unit can move along the vertical guides of the support structure. This dynamic positioning capability reduces the force required compared to sliding the entire heavy assembly along long guides.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The drilling and milling unit is designed with multi-functionality, capable of both drilling operations and engraving operations. The same carriage and drilling unit that provide precise positioning for drilling can also perform engraving of symbols and markings on section members, eliminating the limitation imposed by the heavy support assembly's inertia.

Inventive Principle:

Principle #6Universality (Multi-functionality)
