Modular Machine Tool Table Assembly for Transportable Rigid Frames
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing machine tools for processing plate-shaped workpieces often feature monolithic steel structures that are difficult to transport and assemble, requiring extensive effort during production and installation due to their large size and complexity.
Innovation Solution
A modular machine tool design with prefabricated longitudinal and transverse frame modules connected via fastening means, allowing for standardized, automated production and flexible assembly at the installation site, where modules are surface-treated before assembly for precise alignment and support.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a monolithic welded steel construction is used for the machine table, then structural strength and stability are improved, but transportability and assembly ease deteriorate
Solution Approach 1:
The machine table is divided into multiple modular frame sections that can be manufactured separately, transported easily, and assembled on-site using connection elements. This segmentation maintains structural integrity while dramatically improving transportability and assembly ease compared to monolithic constructions.
2Stability of the object's composition
If a monolithic welded steel construction is used for the machine table, then structural stability is improved, but production cost and assembly time increase
Solution Approach 1:
Individual frame sections are pre-assembled and pre-treated at the manufacturing site before transport. This preliminary action allows for quality control and preparation without requiring time-consuming on-site welding or assembly operations, thereby reducing overall assembly time while maintaining structural stability.
3Adaptability or versatility
If standardized frame modules are used, then manufacturing flexibility and assembly ease are improved, but structural strength may deteriorate
Solution Approach 1:
Multiple standardized frame sections are combined through rigid connection elements to form a unified structure. The connection elements are designed to maintain structural continuity and strength across module joints, ensuring that the assembled modular structure achieves equivalent or superior strength compared to monolithic constructions while retaining manufacturing flexibility.
