Machine Tool Base with Segmented Front Face and Forward Jig
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional vertical machining centers face limitations in lateral movement of workpieces and machining precision due to side plane walls, heat accumulation from chips, and reduced rigidity, which restricts the workpiece machining range and flexibility in chip discharging.
Innovation Solution
A machine tool design with a base having a single orthogonal plane front face, a vertically rotating machining head, and guide-driving means that allows lateral and vertical movement of the machining head, eliminating side plane walls and positioning the jig for improved access and precision, while using a chip conveyer groove to manage heat and enhance rigidity by shortening the force transmission loop.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If side plane walls are added to support the jig, then the jig is stabilized, but the lateral movement range of the machining head is restricted
Solution Approach 1:
The base is divided into a main body portion and a forwardly extended front lower part. The jig is supported by the main body portion while the front lower part remains clear to allow lateral movement. This segmentation resolves the contradiction by providing stability where needed while maintaining movement freedom in other areas.
Solution Approach 2:
The support structure is repositioned from the front lower part to the main body portion of the base, utilizing the vertical dimension and rearward space. This allows the jig to be stabilized without obstructing the lateral movement path of the machining head, effectively using spatial reconfiguration to resolve the contradiction.
2Productivity
If the front lower part of the base is used for chip discharge, then chip removal is facilitated, but heat from chips accumulates and reduces machining precision
Solution Approach 1:
The chip discharge function is extracted from the front lower part of the base and relocated to a chip discharge port in the side face of the main body portion. This separates the chip discharge path from the machining area, allowing efficient chip removal while preventing heat accumulation near the workpiece and maintaining machining precision.
3Ease of operation
If the jig is positioned forwardly extended from the front face, then workpiece accessibility is improved, but the force transmission loop is lengthened reducing rigidity
Solution Approach 1:
The base structure is segmented into a main body portion and a forwardly extended front lower part. The jig is supported by the main body portion at an optimized position that balances accessibility and rigidity, while the front lower part remains clear. This segmentation allows the jig to be accessible while maintaining a short force transmission loop through proper support positioning.
4Stability of the object's composition
If side plane walls are added to support the jig, then lateral stability is improved, but workpiece lateral movement is restricted
Solution Approach 1:
The base is segmented into a main body portion with side plane walls for jig support and a clear front lower part for lateral movement. This segmentation allows lateral stability to be provided where the jig is located while maintaining lateral movement freedom in the front area where workpieces need to be moved.

AI summary
A machine tool, wherein the front face of a base of the machine tool is formed in a single plane and a jig for fixing a workpiece to be machined with a tool is installed extending forwardly from a vertical intermediate front part of the base that defines an area between right and left lateral end front parts of the base having the vertical overall length portions or the vertical roughly overall length portions at right and left end parts of the front face formed in the single plane is formed detachably from the other portions of the base. The jig for fixing the work machined with the tool may be installed in the state of being extended from the vertical intermediate position of the front face in a forward direction.
