Monoblock Vertical Wall Machine Tool Spindle Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing machine tools face increased production and costs due to the need for specially manufactured connecting parts to prevent displacements between the workpiece and tool sides, particularly under high acceleration and machining forces.
Innovation Solution
The machine tool design features horizontal guides on both sides of a vertical wall opening, allowing the X-axis to be separated, and the forces in the Z-direction are diverted and absorbed by the vertical wall, eliminating the need for additional connecting parts by using a monoblock or welded vertical wall and a swiveling workpiece carrier with drive and counter bearings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If connecting beams are used to prevent displacements between workpiece and tool sides, then stability is improved, but device complexity and production costs increase
Solution Approach 1:
The patent merges the vertical wall and horizontal guides into a single integrated monoblock structure. The vertical wall forms a continuous frame with the horizontal guides on both sides of the wall opening, eliminating the need for separate connecting beams. This integration maintains stability while reducing the number of discrete components and assembly requirements.
Solution Approach 2:
The vertical wall structure serves multiple functions simultaneously: it provides structural support, guides the workpiece carrier horizontally, and prevents displacements between workpiece and tool sides. By making the vertical wall multi-functional, the patent eliminates the need for dedicated connecting beams while maintaining all necessary stability functions.
2Stability of the object's composition
If connecting beams are used to prevent displacements between workpiece and tool sides, then stability is improved, but manufacturing costs increase
Solution Approach 1:
The patent combines the vertical wall and horizontal guides into a single monoblock structure that can be manufactured as one piece or pre-assembled unit. This eliminates the need to manufacture and assemble separate connecting beams, reducing production complexity and costs while maintaining the stability function.
Solution Approach 2:
The vertical wall structure provides its own support and guidance functions without requiring additional connecting components. The monoblock design is self-sufficient, providing both vertical support and horizontal guidance through its integrated structure, thereby eliminating the need for separate connecting beam components.
3Loss of substance
If horizontal guides are interrupted by wall opening, then chip accumulation space is created, but guide continuity is reduced
Solution Approach 1:
The horizontal guides are segmented into separate sections on either side of the wall opening. Each guide section is independent and provides guidance for its respective side, while the vertical wall connects them structurally. This segmentation allows chip accumulation space in the middle while maintaining guidance functionality on both sides.
Solution Approach 2:
The guide discontinuity in the horizontal plane is compensated by the vertical dimension. The vertical wall provides structural connection and stability in the vertical direction, while the horizontal guides are intentionally interrupted to allow chip accumulation. The stability is maintained through the three-dimensional integrated structure rather than continuous horizontal guidance.

AI summary
The tool (1) has a Y-carriage (5) vertically displaceable within a wall opening (4), which is provided in a vertical wall (3). The Y-carriage is displaceably guided at the vertical wall, and carries a horizontally displaceable Z-carriage (6) with a horizontal tool spindle (7) i.e. working spindle. A workpiece carrier (8) is arranged before the opening and horizontally displaced in an X-direction. Horizontal guides (11) of the workpiece carrier are provided outside at the vertical wall or on a horizontal passage of the vertical wall. The horizontal guides are disconnected by the wall opening.
