Universal Insert Clamping for Multi-Angle Cutting Tools
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cutting tools require separate tool main units for different types of cutting inserts with varying corner angles, leading to reduced operation efficiency and increased costs due to the need for multiple units, and limited versatility in processing various work materials.
Innovation Solution
A cutting tool with a tool main unit that features a fixing portion capable of selectively fixing multiple types of cutting inserts, including negative and positive types with corner angles exceeding or less than 60°, by utilizing a side wall face with distinct contact portions for each type, allowing for firm holding of four types of inserts with a single unit.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate tool main units are used for different types of cutting inserts, then each cutting insert can be firmly fixed, but operation efficiency drops and costs increase
Solution Approach 1:
The tool main unit is designed with a universal fixing portion that can accommodate multiple types of cutting inserts (negative/positive types with corner angles exceeding or less than 60°) through a standardized clamping mechanism. This allows a single tool main unit to perform multiple functions by fixing different insert types using the same clamping structure, thereby improving operation efficiency while maintaining reliable fixation for each insert type.
2Reliability
If separate tool main units are used for different types of cutting inserts, then each cutting insert can be firmly fixed, but costs increase due to providing multiple units
Solution Approach 1:
The fixing portion employs a standardized clamping structure with clamp members that can universally fix different types of cutting inserts. This design eliminates the need to manufacture separate tool main units for each insert type, reducing manufacturing costs while ensuring reliable fixation through the consistent application of the same clamping mechanism across all insert types.
3Adaptability or versatility
If various different shapes of work materials are processed, then versatility is improved, but the number of holding tools is limited due to tool rest constraints
Solution Approach 1:
The tool main unit is designed as a multi-functional holding tool with a universal fixing portion that can accommodate multiple types of cutting inserts. This allows a single holding tool to process various different shapes of work materials by selecting appropriate cutting inserts, thereby improving processing versatility while reducing the number of holding tools needed and avoiding tool rest constraints.
4Productivity
If a single tool main unit fixes multiple types of cutting inserts, then operation efficiency improves, but the fixing portion must be designed to accommodate different corner angles
Solution Approach 1:
The fixing portion is designed with clamp members that can adapt to different corner angles of cutting inserts through localized adjustment mechanisms. The clamp members are configured to contact specific regions of the cutting inserts (such as the corner portions or side faces) and apply clamping forces appropriately for each insert type, allowing a single fixing portion design to handle multiple insert types with varying corner angles while maintaining operation efficiency.

AI summary
Cutting tool 1 that can firmly hold four types of cutting inserts by one tool main unit 20. A cutting insert 10 of the cutting tool has an approximately triangular stereoscopic shape including three corner portions. The tool main unit has a fixing portion 30 that can selectively fix a plurality of types of cutting inserts, including: a negative type cutting insert whose angle of the corner portion exceeds 60°, a positive type cutting insert whose angle of the corner portion exceeds 60°; a negative type cutting insert whose angle of the corner portion is less than 60°; and a positive type cutting insert whose angle of the corner portion is less than 60°. The fixing portion has a bottom face 40 that contacts a bottom face of the cutting insert, and a side wall face 41 that contacts a side face of the cutting insert. A portion of the side wall face of the fixing portion which contacts the cutting insert differs depending on the type of the cutting insert.
