Cutting Tool Holder Clamp Structure for Stable Attachment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cutting units face issues with unstable holder attachment due to uneven pressing forces, leading to potential durability problems and increased operational complexity.
Innovation Solution
A cutting unit design with a holder and holding block configuration that uses a clamp member with integrated pressing pieces, allowing simultaneous adjustment of pressing forces on the holder, ensuring stable attachment and improved workability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If two independent pressing pieces are used to fix the holder, then the holder can be secured to the holding block, but the pressing forces become uneven and the operation complexity increases
Solution Approach 1:
The patent merges two independent pressing pieces into a single integrated pressing piece with two pressing portions. This pressing piece is formed as one integral structure from a single material, combining the functions of multiple pressing elements. The integration ensures uniform pressing force distribution while simplifying the adjustment operation to a single action, directly resolving the contradiction between attachment stability and operational simplicity
Solution Approach 2:
The single pressing piece is segmented into two distinct pressing portions (first and second pressing portions) that contact different locations on the holder. This segmentation allows the pressing piece to apply force at multiple points simultaneously, ensuring stable attachment of the holder while maintaining the simplicity of a single integrated component for easier operation
2Reliability
If two independent pressing pieces are used to fix the holder, then the holder can be secured to the holding block, but the durability decreases due to uneven pressing forces
Solution Approach 1:
By merging two independent pressing pieces into one integrated pressing piece made from a single material, the patent ensures uniform material properties and consistent pressing force distribution. This eliminates the uneven force distribution that would occur with separate components, preventing localized stress concentrations that lead to wear and failure, thereby improving the durability of the cutting unit while maintaining reliable holder attachment
Solution Approach 2:
The pressing piece is constructed as a homogeneous structure from a single material, ensuring uniform mechanical properties throughout. This homogeneity guarantees consistent pressing force application across both pressing portions, preventing the uneven force distribution that causes accelerated wear and reduces the duration of action of the stationary cutting unit components

AI summary
To stably hold a holder by a holding block while improving the workability of an operation of attaching the holder to the holding block. A clamp member includes a pressing portion that, in a state of being interposed between one inner side surface of a groove of a holding block and an upper surface of a holder, presses the holder toward the other inner side surface of the groove. The pressing portion includes a first protrusion that comes into contact with a first inclined surface of a first cutout of the holder, and a second protrusion that is separated from the first protrusion and comes into contact with a second inclined surface of a second cutout of the holder.
