Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing machine tool systems face challenges in maintaining the relative position between the transport apparatus and the machine tool, which can lead to reduced workpiece processing accuracy due to vibrations from the transport apparatus.
Innovation Solution
A machine tool system that includes a machine tool with a bed, a transport apparatus with legs spaced apart from the bed, and an elastically deformable connecting plate that connects the bed to the legs, allowing for smooth transfer of workpieces while minimizing the transmission of vibrations to the bed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If the legs of the transport apparatus are installed independently of the bed, then vibrations are not transmitted to the bed and workpiece processing accuracy is maintained, but the transport apparatus and machine tool may be displaced relatively to each other
Solution Approach 1:
A connecting plate is introduced as an intermediary component between the bed and the legs of the transport apparatus. This plate serves as a mediator that allows controlled interaction between the two components, enabling both vibration isolation and position stability to be achieved simultaneously.
Solution Approach 2:
The connecting plate's physical parameters (material properties, thickness, dimensions) are optimized to achieve the desired balance between rigidity (for position stability) and flexibility (for vibration isolation). By changing these parameters, the plate can selectively transmit or isolate different types of mechanical disturbances.
2Stability of the object's composition
If the legs of the transport apparatus are mounted on the bed, then relative displacement between transport apparatus and machine tool is prevented, but vibrations are transmitted to the bed and workpiece processing accuracy deteriorates
Solution Approach 1:
The connecting plate acts as an intermediary that decouples the direct mechanical connection between the bed and transport apparatus legs. This intermediary structure allows the system to maintain positional stability while filtering out harmful vibrations before they reach the bed.
Solution Approach 2:
The connecting plate is designed to exploit vibration characteristics by converting harmful high-frequency vibrations into beneficial low-frequency movements or dissipating them through controlled deformation. The plate's elastic properties allow it to absorb and transform vibrational energy, turning a harmful effect into a neutral or even beneficial one.
3Strength
If the plate is made rigid to support the load of the transport apparatus, then the load is reliably supported, but vibrations in the left-right direction are transmitted to the bed
Solution Approach 1:
The connecting plate exhibits different mechanical properties in different directions and locations. It is designed with anisotropic characteristics where it shows high rigidity in the vertical direction for load support, while maintaining flexibility in horizontal directions to isolate vibrations. This local differentiation of mechanical properties allows simultaneous achievement of load-bearing capability and vibration isolation.
Solution Approach 2:
The connecting plate may be constructed using composite materials or composite structures that combine components with different mechanical properties. This allows the plate to exhibit tailored mechanical behavior - rigid in directions where load support is needed, and flexible in directions where vibration isolation is required.

AI summary
A machine tool system includes a machine tool including a processor to process a workpiece with a tool, and a bed on which the processor is mounted, a transport apparatus including two, left and right, legs spaced apart from the bed to transport the workpiece and feed the workpiece to the processor or discharge the workpiece from the processor, and a plate that connects the bed to the legs and is elastically deformable. The plate is upright such that a plate surface is aligned with a front-rear direction, and a connection portion of the plate that connects with the bed and a connection portion of the plate that connects with the legs are displaced in a front-back direction.
