Machine Tool Abutment Layout for Variable-Length Workpiece Support
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The handling and support of workpieces in existing machine tools, such as mitre saws, are not optimal, as the abutment bodies are either stationary or have limited adjustability, leading to suboptimal support for workpieces of varying lengths.
Innovation Solution
The abutment body in the machine tool is designed to be releasably fixed on the machine base in at least two different longitudinal positions with respect to the longitudinal axis, allowing for adjustable positioning to optimize support for workpieces of different lengths.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the abutment body is fixed in a stationary position, then the structure is simple and stable, but the support optimality for workpieces of varying lengths deteriorates
Solution Approach 1:
The abutment body is made adjustable along the longitudinal axis between multiple fixed positions instead of being stationary. This allows the support position to be dynamically changed according to workpiece length requirements, resolving the contradiction between adaptability and structural simplicity by introducing controlled adjustability rather than full complexity.
Solution Approach 2:
The adjustment mechanism divides the abutment body positioning into discrete fixed positions along the longitudinal axis. This segmentation approach provides multiple predetermined support positions that accommodate different workpiece lengths while maintaining structural simplicity through predefined stopping points rather than continuous adjustment complexity.
2Adaptability or versatility
If the abutment body is made adjustable to different longitudinal positions, then the adaptability to workpiece lengths improves, but the device complexity increases
Solution Approach 1:
The holding device incorporates a movable abutment body that can be positioned at multiple fixed locations along the longitudinal axis. This dynamic positioning capability provides adaptability to different workpiece lengths while the holding device maintains relatively simple construction through predefined positioning mechanisms rather than complex continuous adjustment systems.
Solution Approach 2:
The holding device is designed to accommodate the abutment body in multiple fixed positions along the longitudinal axis, making it universally applicable to workpieces of different lengths. This multi-position capability provides versatile support functionality while the holding device itself remains relatively simple in structure compared to continuous adjustment mechanisms.
3Adaptability or versatility
If two abutment bodies are provided in a longitudinal space, then the workpiece support coverage improves, but the device complexity and handling difficulty increase
Solution Approach 1:
Instead of providing two separate abutment bodies, the invention segments the single abutment body into multiple adjustable positions along the longitudinal axis. This allows one abutment body to cover the support function that would otherwise require two bodies, improving handling ease while maintaining adequate support coverage through positional versatility.

AI summary
A machine tool for machining workpieces, wherein the machine tool includes a machine base for setting down on a ground surface. The machine tool further includes a drive assembly arranged on the machine base with a drive motor and a tool receptacle drivable by the drive motor. machine base has a support surface for supporting the workpiece and includes at least one side contact body with a side contact surface. The side contact body is at an angle to the support surface, and extends along a longitudinal axis. The machine tool further includes at least one abutment body with an abutment surface, which can be fixed opposite the support surface by means of a holding device on the machine tool, so that the workpiece, is supported adjacent to the side contact surface sandwiched between the support surface and the abutment surface.
