Machine Tool Support Frame Non-Contact Reinforcement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing machine tool systems face challenges in installing machine tools in limited spaces due to the need for large anchor plates and reinforcement frames to prevent vibration transmission, which increases the space requirements and limits installation flexibility.
Innovation Solution
A support frame structure with left and right stands on the floor surface, reinforced by non-contact insertion of transverse reinforcement members through holes in the machine tool bed, connecting vertically halfway portions of the stands without contacting the inner faces, allowing for reduced space installation and minimizing vibration transmission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the travel rail is supported by stands fixed by anchoring on the floor surface, then the height between the floor surface and the travel rail is increased, but the space required for installation is increased
Solution Approach 1:
The reinforcement member is inserted through a throughhole in the bed in a direction substantially perpendicular to the longitudinal direction of the stands, transitioning from lateral reinforcement to vertical/depth-direction reinforcement. This allows the stands to achieve sufficient strength without requiring large lateral protrusions, thereby reducing installation space while maintaining structural integrity
Solution Approach 2:
The reinforcement member is inserted within the space defined by the throughhole in the bed, utilizing the existing internal space of the bed structure. This nesting approach allows reinforcement without adding external protrusions, keeping the overall footprint compact and reducing installation space requirements
2Strength
If the reinforcement frame protrudes considerably in a direction laterally outwardly of the stands, then the strength of the stands is secured, but the space for installation is increased
Solution Approach 1:
Instead of reinforcing the stands through lateral protrusions, the reinforcement member is inserted through a throughhole in the bed in a direction substantially perpendicular to the longitudinal direction of the stands. This dimensional shift moves the reinforcement from the lateral dimension to the vertical/depth dimension, achieving strength without increasing lateral footprint
Solution Approach 2:
The reinforcement function is extracted from the stand structure itself and relocated to a separate reinforcement member that passes through the bed. This separation allows the bed to provide reinforcement without requiring the stands to protrude laterally, thus reducing installation space while maintaining stand strength
3Object-affected harmful factors
If large anchor plates are used to prevent vibration transmission, then vibration transmission is reduced, but the installation space is increased
Solution Approach 1:
The vibration isolation function is extracted from the anchor plates and stands and relocated to the reinforcement member passing through the bed. By removing the reinforcement function from the lateral structure, smaller anchor plates can be used while maintaining vibration isolation effectiveness, thereby reducing installation space
Solution Approach 2:
The reinforcement member acts as an intermediary element that provides vibration isolation by passing through the bed structure. This intermediary approach allows vibration control without requiring large anchor plates, as the reinforcement member mediates between the stands and the bed to prevent vibration transmission
