Orthogonal-Frame Machining Structure for Rigid 5-Axis Support
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing machining apparatuses face challenges in ensuring sufficient rigidity to maintain machining stability and accuracy, particularly when supporting a workpiece that is rotated and moved, as the rigidity of the supporting structures is often insufficient, leading to potential deterioration in machining precision.
Innovation Solution
The machining apparatus incorporates a frame with orthogonal surfaces to support moving and rotating mechanisms, including a Z-axis, X-axis, and Y-axis moving mechanisms, along with A-axis and B-axis rotating mechanisms, to provide enhanced rigidity and stability, ensuring the workpiece is securely held and rotated without compromising positional accuracy.

Engineering Contradiction Analysis
1Device complexity
If the workpiece is moved and rotated while supported by the side surface of the frame, then the apparatus structure is simplified, but the rigidity of the supporting structure is insufficient
Solution Approach 1:
The patent transitions from supporting the workpiece on the side surface (horizontal support) to supporting it on the upper surface (vertical support). This dimensional change allows the workpiece to be supported by the rigid upper surface of the frame rather than the side surface, thereby improving supporting rigidity while maintaining structural simplicity
Solution Approach 2:
The patent introduces a separate supporting mechanism that replicates the support function independently from the frame structure. This supporting mechanism includes a supporting table and supporting legs that provide dedicated rigid support for the workpiece, separating the support function from the frame's primary structural role
2Reliability
If the rigidity of supporting portions is increased, then machining stability is improved, but the apparatus structure becomes more complex
Solution Approach 1:
The patent divides the supporting function into separate components: the frame provides overall structural support, while the dedicated supporting mechanism (supporting table, supporting legs, and supporting portions) provides localized rigid support for the workpiece. This segmentation allows each component to be optimized for its specific function without unnecessarily increasing overall complexity
Solution Approach 2:
The supporting mechanism acts as an intermediary between the frame and the workpiece. It transfers the workpiece weight and machining loads to the frame through rigid supporting portions, ensuring machining stability while keeping the frame structure relatively simple. The intermediary absorbs the complexity of rigid support requirements

AI summary
A machining apparatus includes a first frame including a first surface formed along a Z-axis direction and a second surface formed along a Y-axis direction. An X-axis moving mechanism and a Z-axis moving mechanism are disposed on the first surface side of the first frame. A Y-axis moving mechanism is disposed on the second surface side of the first frame. A second frame supports the first frame from the second surface side of the first frame. An A-axis rotating mechanism, a B-axis rotating mechanism, and a supporting mechanism that supports an object to be machined are moved by the Y-axis moving mechanism. The t Y-axis moving mechanism is disposed in a space located below the first frame in the Z-axis direction, and formed by the second flame.
