Machine Tool Movable Modules Recessed Bed Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Machine tools with movable modules orthogonal to the main spindle axis face challenges in operator access and maintenance due to limited layout flexibility, leading to reduced operation and maintenance performance.
Innovation Solution
The machine tool design includes movable modules that can align with fixed modules via a recessed bed, allowing for improved accessibility and layout flexibility, enabling easier maintenance and operation by allowing modules to move into positions where operators can easily reach them.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If modules are arranged in parallel and made movable orthogonal to the main spindle axis to transfer workpieces, then processing productivity is improved, but operator access and maintenance performance are reduced
Solution Approach 1:
The patent introduces a recess in the bed structure that creates a new spatial dimension for operator access. This recess allows operators to approach movable modules from the rear side (orthogonal direction) rather than only from the front, effectively adding another dimension to the access pathway while maintaining the movable module configuration for high productivity
2Productivity
If modules are arranged in parallel and made movable orthogonal to the main spindle axis, then workpiece transfer efficiency is improved, but maintenance performance is reduced
Solution Approach 1:
The recess structure enables maintenance personnel to access movable modules from the rear side, providing an alternative approach path that does not interfere with the workpiece transfer function. This spatial arrangement allows maintenance activities to be performed independently without compromising the workpiece transfer efficiency
3Productivity
If modules are positioned near the center of the bed for workpiece transfer, then processing productivity is improved, but operation direction is limited
Solution Approach 1:
The recess allows operators to access modules from the rear side (Y-axis direction) in addition to the front side (X-axis direction), effectively adding another degree of freedom for operational approaches. This enables versatile operation directions while maintaining the centralized module arrangement for high productivity

AI summary
A machine tool (100) having a good processing productivity of a workpiece, and capable of improving a maintenance performance and an operation performance is provided. The machine tool (100) includes two fixed modules (M1, M3) and two movable modules (M2, M4) each of which having a main spindle (11), a headstock (12), and a tool post (13) being integrally formed, and a bed (1) on which these are installed. The movable modules (M2, M4) are provided on the bed (1) to be movable in the Y-axis direction, the fixed modules (M1, M3) are fixed on the bed (1) on the opposite sides of the these movable modules, and a recess (8) is provided next to the fixed module (M3), the recess being formed by cutting out the bed (1). The movable modules (M2, M4) are movable such that the axis lines of the main spindles of the movable modules are aligned with the axis line of the main spindle (11) of the fixed module (M1) or the fixed module (M3). The movable module (M4) is movable to the opposite position (P3) of the recess (8).
