Cutting Tool Holder Blade with Spring-Loaded Set-Up Body
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cutting tools require time-consuming manual adjustments and fine positioning of holder blades, leading to long setup times and increased costs due to the need for precise radial alignment of cutting inserts during tube cutting operations.
Innovation Solution
A cutting tool design featuring a spring-loaded set-up body between the basic and support bodies, with a screw joint and keyhole-like through holes in the holder blade for easy mounting and dismounting, allowing for quick repositioning without losing exact radial alignment, and an optional detachable sensor for position determination.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If manual measuring and fine adjustment of holder blade axial position is performed to achieve precise radial alignment, then positioning accuracy is improved, but setup time increases significantly
Solution Approach 1:
The holder blade is pre-positioned in the support body during manufacturing with a predetermined axial position that corresponds to the exact radial alignment requirement. This preliminary positioning action eliminates the need for time-consuming manual measuring and fine adjustment during setup, while maintaining the required positioning accuracy of 0.1 mm
Solution Approach 2:
A的定位结构（包括定位孔、定位销或定位面）作为中介元件，在 holder blade 和 support body 之间传递精确的位置信息。通过这个中介定位机构，holder blade 能够快速准确地定位到预设的轴向位置，无需人工测量和调整
2Reliability
If multiple clamping jaws are used to secure the holder blade firmly, then clamping reliability is improved, but the complexity of mounting and dismounting operations increases
Solution Approach 1:
The clamping function is segmented into multiple independent clamping jaws that can be individually actuated. Each clamping jaw can be opened or closed independently, allowing the holder blade to be mounted or dismounted by sequentially releasing the clamping jaws one by one, thereby simplifying the overall operation while maintaining reliable clamping
Solution Approach 2:
The clamping jaws are designed to be movable rather than fixed, allowing them to dynamically adjust their position and apply clamping force only when needed. During mounting or dismounting, the clamping jaws can be easily repositioned or released, reducing operational complexity while ensuring reliable clamping during cutting operations

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables rapid and precise repositioning of holder blades and cutting inserts, significantly reducing setup times and ensuring uniform wear of cutting inserts, thus minimizing operational downtime and costs.
Implementation Method 1
a set-up body (12) being arranged between the support body (11) and the basic body (10) and in relation to which the support body (11) is fixable in a desired axial position as soon as the setting operation has been carried out, and against the action of which the set-up body (12) is actuated by a spring device aiming to displace the set-up body (12) axially in relation to the basic body (10)

AI summary
The invention relates to a cutting tool that is intended above all for tube cutting machines and includes a tool holder and a dismountable holder blade having replaceable cutting inserts, the tool holder including a basic body (10) as well as a support body (11) for the holder blade (7). According to the invention, between the basic body (10) and the support body (11), there is arranged a set-up body (12), by means of which the support body - and thereby the holder blade - can be set and fixed in the exact, desired spatial positions in the machine without time-consuming measuring and fine adjustment operations. In addition, the holder blade is fixed in the support body by means of a single simple screw, which allows a flexible mounting and dismounting of the same.
