Horizontal Machine Tool Back-Face Saddle Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional horizontal machine tools have a large size due to the translation mechanism of the column on the rear part of the bed, leading to a large upper face in the front-rear direction, which results in a bulky construction.
Innovation Solution
A horizontal machine tool design featuring a base frame with a saddle supporting part, an X-axis saddle, a Y-axis saddle, and a spindle device, where the translation mechanisms are positioned on the back face of the saddle supporting part, allowing the spindle device to slide in the front-rear direction and the workpiece supporting member to be mounted in front, reducing the size and weight of the base frame and enabling compact arrangement of components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the translation mechanism is positioned on the rear part of the bed, then the spindle device can be supported, but the upper face of the bed becomes large in the front-rear direction
Solution Approach 1:
The translation mechanism is relocated from the rear part of the bed to the back face of the saddle supporting part, utilizing the vertical dimension and rearward projection space. This dimensional relocation allows the bed's upper face to be shortened in the front-rear direction while the translation mechanism remains functionally positioned to support the spindle device through the saddle structure.
2Reliability
If the translation mechanism is positioned on the rear part of the bed, then the spindle device can be supported, but the entire construction becomes big
Solution Approach 1:
The translation mechanism is repositioned to utilize the vertical and rearward space of the saddle supporting part rather than occupying horizontal bed space. This dimensional restructuring compactly arranges components, reducing the overall volume of the machine tool while maintaining spindle device support functionality.
3Adaptability or versatility
If the workpiece supporting member is mounted on the base part in front of the saddle supporting part, then design freedom is enhanced, but the arrangement becomes complex
Solution Approach 1:
The machine tool is segmented into distinct functional zones: the workpiece supporting member is independently mounted on the base part in front of the saddle supporting part, while the translation mechanisms are positioned on the back face of the saddle supporting part. This segmentation allows each component to be optimized independently, enhancing workpiece support design freedom without significantly increasing overall arrangement complexity.

AI summary
Provided is a horizontal machine tool with a base frame including a base part and a saddle supporting part vertically standing on the base part; an X-axis saddle mounted on the back face of the saddle supporting part and capable of sliding in the left-right direction via an X-axis translation mechanism; a Y-axis saddle mounted on the X-axis saddle and capable of sliding in the up-down direction via a Y-axis translation mechanism; and a spindle device mounted on the Y-axis saddle and capable of sliding in the front-rear direction via a Z-axis translation mechanism. The horizontal machine tool is adapted such that a workpiece supporting member is installed on the base part in front of the saddle supporting part. This configuration can reduce the size and weight of the entire construction.
