Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If traditional alignment processes are used for mounting tool holders on tool supports, then the mounting can be completed, but the alignment process becomes complex and error-prone, reducing manufacturing precision
Solution Approach 1:
The patent introduces a stopping means as an intermediary element between the tool holder and tool support. This stopping means features a stopping surface that cooperates with a contact surface on the tool support, creating a simple geometric interface that automatically ensures precise alignment during mounting without requiring complex adjustment procedures
Solution Approach 2:
The stopping means is pre-positioned on the tool holder with its stopping surface oriented to engage the contact surface on the tool support. This preliminary positioning arrangement ensures that when the tool holder is mounted, the alignment is automatically achieved through the geometric relationship between the stopping surface and contact surface, eliminating the need for complex post-mounting alignment adjustments
2Manufacturing precision
If manual alignment adjustments are made during mounting, then positioning accuracy can be improved, but the mounting process becomes more time-consuming and labor-intensive
Solution Approach 1:
The stopping means is designed to automatically perform the alignment function when the tool holder is mounted on the tool support. The geometric relationship between the stopping surface and contact surface self-adjusts to ensure precise positioning, eliminating the need for manual alignment adjustments and significantly reducing mounting time
3Manufacturing precision
If stopping means is added to the tool holder or tool support, then alignment precision is improved, but the device structure becomes more complex
Solution Approach 1:
The stopping means is implemented as a localized feature rather than a complete structural system. The stopping surface on the stopping means and the contact surface on the tool support create a focused alignment interface at a specific location, maintaining simplicity in the overall device structure while achieving precise alignment locally

AI summary
A tool clamping device having a tool holder (2) holding a tool (7, 8) for insertion into a socket of a tool support (1), such as a turret disc is designed such that a receiving body (16) of the tool holder and the tool support (1) have bearing surfaces (16, 3) to be arranged to one another and devices (14, 15) for fastening the tool holder on the tool support. The receiving body or the tool support has at least one stopping means (28), which projects axially over its bearing surface and is disposed on one side of the receiving body or tool support. The tool support or the receiving body has at least one contact surface for the stopping means. There is provided elastic means (36, 44) by means of which the stopping means can be laterally held in place on the contact surface under prestress.
