Centering Elements for Machine Tool Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing devices for positioning tools or workpieces on machine tools require complex and expensive precise alignment, often consuming excessive space and resources.
Innovation Solution
The use of separate centering elements that can move initially and are then permanently fixed using holding means like adhesives or bracing, allowing for precise alignment on a holder before being glued in place, reducing space requirements and simplifying the application process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If traditional precise alignment methods are used to position tools or workpieces on machine tools, then positioning precision is improved, but device complexity and installation space increase
Solution Approach 1:
The positioning system is divided into separate centering elements that can be independently positioned and adjusted on the tool or workpiece, rather than requiring complex integrated alignment mechanisms. Each centering element can be individually adjusted to achieve precise positioning.
Solution Approach 2:
Centering elements serve as intermediary components between the tool/workpiece and the holder, enabling precise positioning through a simplified intermediate step rather than direct complex alignment between the main components.
2Manufacturing precision
If traditional precise alignment methods are used to position tools or workpieces on machine tools, then positioning precision is improved, but installation space increases
Solution Approach 1:
The positioning function is segmented into multiple small centering elements distributed on the tool or workpiece surface, replacing a single large complex alignment mechanism, thereby reducing overall space requirements.
Solution Approach 2:
The centering elements are arranged in specific geometric patterns (e.g., circular patterns around a central axis) to achieve precise positioning in multiple dimensions through a compact two-dimensional layout, reducing the need for extensive three-dimensional alignment space.
3Manufacturing precision
If centering elements are permanently fixed before positioning, then positioning precision is improved, but ease of operation deteriorates
Solution Approach 1:
The centering elements are pre-installed on the tool or workpiece in a movable state, allowing for easy adjustment and positioning. After the precise position is achieved, they are then permanently fixed, combining the benefits of ease of adjustment with final positioning precision.
Solution Approach 2:
The centering elements transition from a movable state during positioning to a fixed state after positioning is complete, allowing the system to adapt its properties based on the operational phase - mobile during adjustment, stationary during operation.

AI summary
The invention relates to a device for positioning a tool or workpiece on a machine tool, in which essentially centring elements (30) are fitted in the tool or workpiece (10) with the aid of an adhesive, wherein the centring elements (30) are aligned exactly on a reference holder (20) as long as the adhesive has not cured.Advantages: low overall height, and consequently further insertion of the tool or workpiece possible; simple production; - no high-precision bores required in the tool or workpiece.
