Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional machining centers with four-beam assemblies are bulky, heavy, and have limited machining capability due to their size and weight, restricting the machining stroke and processing capacity, especially for parts like automobile hubs.
Innovation Solution
A machining center design featuring a single beam structure with multiple main shafts, where the beam is supported by columns and sliders that allow for synchronous or asynchronous operation, reducing size and weight while enhancing processing capacity through a more efficient layout and stress distribution.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a four-beam assembly system is used, then the machining center has sufficient structural strength, but the volume and weight increase, reducing machining stroke and processing capability
Solution Approach 1:
The patent merges multiple beam functions into a single beam structure. The first beam serves as both a support beam for columns and a carriage beam for sliders, eliminating the need for separate fourth beams. This consolidation reduces the overall volume and weight of the machining center while maintaining structural integrity through optimized load distribution paths.
Solution Approach 2:
The patent segments the beam structure into functionally distinct zones within a unified single beam. The beam is divided into a support beam section with column installations and a carriage beam section with slider installations, allowing each zone to be optimized for its specific function while reducing overall structural complexity compared to four-beam assemblies.
2Strength
If a four-beam assembly system is used, then the machining center has sufficient structural strength, but the weight increases, reducing machining stroke and processing capability
Solution Approach 1:
The patent combines multiple beam functions into a single beam structure, eliminating redundant structural elements. The first beam simultaneously serves as both support beam and carriage beam, reducing the total weight of the stationary structure while maintaining sufficient strength through optimized load distribution and structural reinforcement at critical zones.
Solution Approach 2:
The patent changes the structural parameters by transitioning from a four-beam assembly to a single-beam configuration. This parameter change reduces the overall weight of the machining center structure while compensating for strength requirements through localized reinforcement and optimized material distribution in critical load-bearing areas.
3Volume of moving object
If a single beam structure with multiple main shafts is used, then the volume and weight are reduced, but the structural complexity increases
Solution Approach 1:
The patent segments the single beam into functionally distinct zones: a support beam section for column installations and a carriage beam section for slider installations. This segmentation organizes the structural complexity by assigning specific functions to specific zones, making the design more manageable and easier to manufacture despite the reduced overall structure.
Solution Approach 2:
The patent applies multi-functionality to the single beam structure, where the first beam serves multiple purposes: supporting columns, carrying sliders, and providing mounting surfaces for various components. This universal design reduces the need for separate specialized structures, thereby reducing volume while managing complexity through functional integration.
4Productivity
If multiple main shafts are arranged on a single slider, then the processing capability is enhanced, but the precision of positioning may be affected
Solution Approach 1:
The patent segments the slider arrangement into two separate sliders (first slider and second slider) positioned on opposite sides of the beam. Each slider carries one or more main shafts and can be positioned independently along the beam. This segmentation maintains positioning precision by allowing each slider to be independently controlled and aligned, while still achieving enhanced processing capability through the combined operation of multiple sliders and main shafts.
Solution Approach 2:
The patent employs asymmetric positioning of sliders on opposite sides of the beam structure, with each slider independently controllable. This asymmetric arrangement allows for balanced load distribution and independent positioning control, maintaining manufacturing precision while enabling multiple main shafts to operate simultaneously for enhanced productivity.

AI summary
A machining center configured for machining workpieces includes at least one column, a beam, at least one slider, a first driving member, a second driving member, a first main shaft and a second main shaft. The column can be configured for supporting the beam. The slider can be disposed on the beam and slidable along a length direction of the beam. Both the first main shaft and the second main shaft can be arranged on the slider and located on two opposite sides of the beam. The first driving member can be configured for driving the slider to slide relative to the beam. The second driving member can be configured for driving the first main shaft and the second main shaft to operate. The first main shaft and the second main shaft can be configured for synchronously or asynchronously machining the workpieces.
