Rotary Tool Holder Sleeve for Simultaneous Insert Radius Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Rotary cutting tools lack an effective mechanism for simultaneously adjusting the radial position of insert cartridges, limiting the ability to adjust the cutting diameter efficiently.
Innovation Solution
A tool holder with an adjustment sleeve and insert cartridges that allow for rotational displacement, enabling the tool holder to be adjusted between inner and outer positions by rotating the adjustment sleeve, thereby changing the radial distance of the insert pockets from the central axis, allowing for adjustable cutting diameters.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a rotary cutting tool is equipped with an adjustment mechanism for individual insert cartridges, then the cutting diameter can be adjusted, but the adjustment process becomes time-consuming and inefficient
Solution Approach 1:
The patent combines multiple individual adjustment mechanisms into a single integrated adjustment mechanism. The adjustment sleeve simultaneously engages with multiple insert cartridges through grooves, allowing all cartridges to be adjusted together by one rotational motion, thus merging several adjustment operations into one unified action that significantly improves efficiency
Solution Approach 2:
The adjustment sleeve serves multiple functions: it simultaneously adjusts the radial position of multiple insert cartridges, maintains their relative spacing, and enables both individual and collective adjustment modes. This multi-functional component eliminates the need for separate adjustment mechanisms for each cartridge
2Manufacturing precision
If the adjustment mechanism allows independent adjustment of each insert cartridge, then precise cutting diameter control is achieved, but the device complexity increases
Solution Approach 1:
The adjustment mechanism is segmented into modular components: the adjustment sleeve with grooves, the insert cartridges with engagement surfaces, and the holder body with recesses. This segmentation allows each component to perform a specific function while maintaining overall simplicity, avoiding the need for complex interconnected adjustment systems
Solution Approach 2:
Instead of having multiple independent adjustment mechanisms that each control one cartridge, the patent inverts the approach by using a single adjustment sleeve that controls all cartridges simultaneously. This inversion simplifies the overall mechanism while maintaining the ability to achieve precise cutting diameter control

AI summary
A rotary cutting tool includes a tool holder. The tool holder has holder body and an adjustment sleeve circumferentially disposed thereabout. The adjustment sleeve has an at least one sleeve adjustment groove which decreases in distance from a sleeve central axis in a rotational sleeve direction. The tool holder further has a plurality of insert cartridges, each having an insert pocket and at least one cartridge pin. At least one pin is located in a respective sleeve adjustment groove. The tool holder is adjustable between inner and outer adjusted positions by rotating the adjustment sleeve in the rotational sleeve direction. In the outer adjusted position, the insert cartridges are displaced in an outwards adjusted direction so that the insert pockets are radially outwards compared to the inner adjustment position.
