Cutting Insert Clamping Holder for Fast Tool Repositioning

Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing cutting tools require re-adjustment of the clamping claw position every time a cutting insert is changed, leading to inefficiencies in tool setup and maintenance.

Innovation Solution

The cutting tool design separates the functions of position adjustment and clamping fixation by using a clamping holder secured to the main body in a positionally adjustable manner, allowing the cutting insert to be changed without re-adjusting its position through a clamping claw that is indirectly tensioned via a clamping holder.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the clamping claw directly tensions the cutting insert against the main body, then the clamping fixation is achieved, but the position adjustment must be performed every time the cutting insert is changed

Engineering Contradiction:

Improvecutting insert change efficiencyVSAvoidsetup time for position adjustment

Core Design Contradiction:

Ease of operationVSLoss of time

Solution Approach 1:

The device is segmented into three functional components: the main body with bearing surface, the clamping holder with position adjustment capability, and the clamping claw for fixation. This segmentation allows the clamping holder to maintain position while the clamping claw is released for insert changes, eliminating repeated adjustment needs.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The clamping holder acts as an intermediary between the main body and the cutting insert. It is positioned against the bearing surface on the main body and provides a stable reference position, allowing the cutting insert to be changed without disturbing the position setting.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Strength

If the clamping claw is pressed against the main body by a tensioning screw, then the clamping fixation is achieved, but the cutting insert cannot be changed without loosening the tensioning screw

Engineering Contradiction:

Improveclamping forceVSAvoidcutting insert replacement

Core Design Contradiction:

StrengthVSEase of operation

Solution Approach 1:

The clamping function is separated from the fixation function. The clamping holder provides stable positioning while the clamping claw with tensioning screw provides adjustable clamping force. This allows the cutting insert to be replaced by releasing only the clamping claw, not the entire positioning system.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The clamping claw is designed to be dynamically adjustable via the tensioning screw, allowing the clamping force to be modified or released as needed for insert changes, while the clamping holder maintains a fixed position relative to the main body.

Inventive Principle:

Principle #15Dynamics
