Movable Support Blocks for Stable Panel Machining Under Load
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing support devices for workpieces in machining processes fail to effectively counteract the forces generated during machining, leading to instability and potential tool pull-out issues.
Innovation Solution
A movable support device with two transversely displacing support frames, one equipped with suction elements and the other with sliding elements, is used to securely fix and support workpieces on a machine bed, allowing for external adjustment to match the machining forces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a stationary support device is used, then the structure is simple, but it cannot counteract machining forces effectively leading to tool pull-out
Solution Approach 1:
The support device transitions from a stationary structure to a dynamic system with two support frames that can displace transversely relative to each other. This dynamic capability allows the support device to adapt to and counteract machining forces during drilling, milling, and sawing operations, preventing tool pull-out while maintaining structural integrity.
Solution Approach 2:
The support device is divided into two separate support frames (first support frame and second support frame) that can move independently. This segmentation allows each frame to be equipped with different functional elements (suction elements on one frame, sliding elements on the other) and enables transverse displacement to accommodate machining forces.
2Adaptability or versatility
If fixed support elements are used, then the device structure is simple, but it cannot adapt to different machining forces
Solution Approach 1:
The support frames are designed to be movable rather than fixed, allowing them to displace transversely in response to different machining forces. This dynamic adaptability enables the same support device to handle various machining operations (drilling, milling, sawing) with different force requirements without requiring complete redesign.
3Reliability
If suction elements alone are used, then workpiece fixation is achieved, but support against lateral machining forces is insufficient
Solution Approach 1:
The invention combines two different support mechanisms: suction elements for workpiece fixation and sliding elements for lateral force resistance. By merging these two functional systems on separate but coordinated support frames, the device achieves both secure workpiece attachment and effective counteraction of machining forces during operations like drilling, milling, and sawing.
Solution Approach 2:
The support device separates the fixation function (suction elements on first support frame) from the lateral support function (sliding elements on second support frame). This functional segmentation allows each element to be optimized for its specific purpose while working together to provide comprehensive workpiece support.

Function Achieved in This Case
The support device effectively secures workpieces against machining forces, enhancing stability and preventing tool pull-out during operations like drilling, milling, and sawing by dynamically adjusting its position to align with the workpiece support surface.
