Adjustable Cutting Tool Blade Mount for Precise Edge Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cutting tools lack precision in position adjustment of the cutting edge, leading to potential displacement and misalignment during the cutting process.
Innovation Solution
A cutting tool design that includes a body, a blade, a first attachment screw, an adjustment piece, and a second attachment screw, allowing for precise adjustment of the blade's position in both the radial and axial directions through the use of an adjustment piece positioned between the blade side surface and the pocket's contact surface, with the second attachment screw facilitating stable movement along the axial direction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a conventional cutting tool design is used, then the structure is simple, but the precision in position adjustment of the cutting edge is insufficient
Solution Approach 1:
The cutting tool is divided into functionally independent segments: the blade assembly, the adjustment piece, and the body. The adjustment piece is a separate component that can be independently positioned between the blade side surface and the pocket contact surface, allowing precise radial adjustment without complicating the overall structure. This segmentation enables high positioning precision while maintaining structural simplicity.
Solution Approach 2:
The adjustment piece serves as an intermediary element between the blade and the body. It is disposed between the blade side surface and the contact surface of the pocket, enabling precise control of the blade's radial position. This intermediary component facilitates accurate position adjustment without requiring complex adjustment mechanisms, thus resolving the contradiction between precision and structural complexity.
2Manufacturing precision
If the space between blade side surface and contact surface is reduced for better precision, then positioning accuracy improves, but the adjustment range is limited
Solution Approach 1:
The adjustment piece is designed to be movable along the axial direction through the second attachment screw, transforming a static gap into a dynamic adjustment mechanism. This allows the space between the blade side surface and contact surface to be precisely controlled within a limited range, achieving high positioning accuracy while maintaining adaptability through axial movement. The dynamic adjustment capability resolves the contradiction between precision and adjustment range.
3Manufacturing precision
If the second attachment screw is used to move the adjustment piece along the axial direction, then position adjustment precision is improved, but the device complexity increases
Solution Approach 1:
The second attachment screw performs multiple functions: it secures the adjustment piece to the body and simultaneously enables precise axial movement of the adjustment piece for position adjustment. This multi-functional design reduces the need for separate adjustment mechanisms, achieving high position adjustment precision without significantly increasing device complexity. The universal screw resolves the contradiction between precision and component count.

AI summary
A cutting tool is rotatable about a central axis and has a front end in an axial direction along the central axis. The cutting tool includes a body, a blade, a first attachment screw, an adjustment piece, and a second attachment screw. The body has an outer peripheral surface. A pocket is formed in the outer peripheral surface at an end portion on the front end side. The blade is attached to the body by screwing the first attachment screw into the body in the pocket. The blade has a blade side surface facing inward in a radial direction that is orthogonal to the axial direction and that passes through the central axis. An inner wall surface of the pocket has a contact surface facing the blade side surface with a space being interposed between the blade side surface and the contact surface in the radial direction.
