Adjustable Insert Cartridge Tool Holder for Variable Cutting Diameter
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Rotary cutting tools lack an effective adjustment mechanism for simultaneously adjusting the radial position of insert cartridges, which limits the flexibility in achieving varying cutting diameters.
Innovation Solution
A tool holder with an adjustable sleeve and insert cartridges that allow for radial adjustment through a spiral groove mechanism, enabling the tool to be positioned between an inner and outer adjusted position to vary the cutting diameter.
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 radial position of each insert cartridge can be adjusted independently, but the complexity of the adjustment mechanism increases significantly
Solution Approach 1:
The patent combines multiple individual adjustment mechanisms into a single unified adjustment mechanism. The adjustment sleeve with spiral grooves simultaneously controls the radial position of all insert cartridges through a common adjustment element, reducing the number of separate adjustment components while maintaining individual adjustability of each insert cartridge.
Solution Approach 2:
The adjustment sleeve serves multiple functions: it simultaneously adjusts the radial position of all insert cartridges, provides precise positioning through spiral grooves, and enables both individual and collective adjustment of insert cartridges. This multi-functional design reduces the need for separate adjustment mechanisms for each insert cartridge.
2Adaptability or versatility
If no adjustment mechanism is provided, then the device complexity remains low, but the ability to achieve varying cutting diameters is limited
Solution Approach 1:
The patent introduces a dynamic adjustment capability to the tool holder through the adjustment sleeve and spiral groove mechanism. This allows the cutting tool to adapt its cutting diameter dynamically by adjusting the radial position of insert cartridges, transforming a static structure into a dynamically adjustable one.
Solution Approach 2:
The spiral grooves in the adjustment sleeve enable precise control of the radial position parameter of insert cartridges. By rotating the adjustment sleeve, the cutting diameter parameter can be varied within a specific range, allowing the tool to accommodate different machining requirements without changing the basic tool structure.

AI summary
A rotary cutting tool (20) includes a tool holder (22). The tool holder (22) has holder body (24) and an adjustment sleeve (44) circumferentially disposed thereabout. The adjustment sleeve (44) has an at least one sleeve adjustment groove (62) which decreases in distance from a sleeve central axis (A) in a rotational sleeve direction ( DRS). The tool holder (22) further has a plurality of insert cartridges (26), each having an insert pocket (30) and at least one cartridge pin (78). At least one pin (78) is located in a respective sleeve adjustment groove (62). The tool holder is adjustable between inner (Fig. 12) and outer (Fig 13 or Fig. 14) adjusted positions by rotating the adjustment sleeve (44) in the rotational sleeve direction ( DRS). In the outer adjusted position, the insert cartridges (26) are displaced in an outwards adjusted direction so that the insert pockets (30) are radially outwards compared to the inner adjustment position.
