Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a traditional clamping device with multiple clamping segments and a spiral bolt is used, then the tool holder can be securely clamped, but the device requires complex modifications and adjustments to the turret body for different tool holders

Engineering Contradiction:
Improveadaptability to different tool holdersVSAvoidcomplexity of turret body modifications
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The clamping device is divided into independent clamping elements (first and second clamping elements) that can be adjusted relative to each other. Each clamping element has its own guide pin and clamping jaw, allowing independent positioning to accommodate different tool holder geometries without modifying the turret body.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The clamping device is designed with adjustable clamping elements that can adapt to various tool holder types and geometries. The guide pins can be positioned at different locations and the clamping jaws can be adjusted to different positions, making the same clamping device universal for different tool holders without requiring turret body modifications.

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Adaptability or versatility

If the clamping device is designed with fixed clamping elements, then the structure is simple, but it cannot easily adapt to different tool holder geometries

Engineering Contradiction:
Improveadaptability to different tool holdersVSAvoidease of installation
Core Design Contradiction:
Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

The clamping elements are made adjustable rather than fixed. The first and second clamping elements can be positioned at different locations along their respective guide pins, and the actuating element can be adjusted to provide different clamping forces and positions, enabling adaptation to various tool holder geometries while maintaining a relatively simple structure.

Inventive Principle:
Principle #15Dynamics

3Manufacturing precision

If conical clamping surfaces are used on the clamping jaws, then the tool holder is drawn evenly into the receiving opening, but the manufacturing precision requirements increase

Engineering Contradiction:
Improveevenness of tool holder drawingVSAvoidease of clamping element fabrication
Core Design Contradiction:
Manufacturing precisionVSEase of manufacture

Solution Approach 1:

The clamping jaws are equipped with conical or inclined surfaces instead of flat surfaces. These conical surfaces guide the tool holder evenly into the receiving opening during the clamping process, distributing the drawing force uniformly and preventing misalignment, though they do require precise manufacturing of the conical geometry.

Inventive Principle:
Principle #14Spheroidality (Curvature)

AI summary

The invention relates to a tool turret with a turret body (1) and a clamping device (3) for clamping a tool holder (6) in a receiving opening (2) of the turret body (1). Known tool turrets of this type exhibit uneven clamping. The objective of creating a tool turret that enables a more uniform clamping process is achieved by the clamping device (3) comprising two clamping elements (10, 11) that are displaceable relative to each other transversely to a central axis (13) of the receiving opening (2) by means of a common actuating element (12).
