Tool Cassette Integrated Adjustment Device for Cutting Insert Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cutting tools with small nominal diameters or carrier bodies made of difficult-to-machine materials face challenges in economic machining and precise adjustment of cutting inserts due to complex processing requirements for accommodating wedge mechanism components.
Innovation Solution
A tool cartridge with an integrated adjustment device that allows radial, axial, and angular positioning relative to the carrier body, eliminating the need for complex bores or recesses on the carrier body by relocating the adjustment mechanism within the tool cartridge itself, which interacts with the carrier body's side walls to adjust the tool cartridge's position using adjustable wedges and a clamping screw.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If the wedge mechanism components are accommodated on the carrier body, then the cutting insert can be adjusted, but the carrier body requires complex processing which increases manufacturing difficulty and cost
Solution Approach 1:
The patent divides the adjustment system into two separate parts: the carrier body and the tool cartridge. The tool cartridge is designed as an independent module containing the wedge mechanism components, which can be manufactured separately and then assembled to the carrier body. This segmentation allows the carrier body to be processed simply while the complex adjustment mechanism is housed in the tool cartridge, resolving the contradiction between adjustment precision and manufacturing ease.
Solution Approach 2:
The tool cartridge serves as an intermediary component between the carrier body and the cutting insert. It contains the wedge mechanism components that enable precise adjustment of the cutting insert, while interacting with the carrier body through a simplified interface. This intermediary structure allows the complex adjustment functionality to be achieved without requiring complex processing of the carrier body itself.
2Strength
If the carrier body is made of difficult-to-machine material, then tool strength and durability are improved, but machining the carrier body becomes more difficult and expensive
Solution Approach 1:
By segmenting the tool into carrier body and tool cartridge components, the patent allows the carrier body to be made from high-strength difficult-to-machine materials without requiring extensive machining. The tool cartridge, which requires precise machining for the wedge mechanism, can be made from easier-to-machine materials and attached to the carrier body, thus resolving the contradiction between strength requirements and manufacturing ease.
3Ease of operation
If the tool cartridge has integrated adjustment device, then the adjustment mechanism is compact and easy to operate, but the tool cartridge structure becomes more complex
Solution Approach 1:
The patent merges the wedge mechanism components and the guide structures into a single integrated tool cartridge assembly. This integration allows the adjustment function to be operated through a single compact interface while housing all necessary components within the tool cartridge, achieving ease of operation despite the internal structural complexity.

Function Achieved in This Case
Enables easy and economical machining of cutting tools with small diameters or difficult-to-machine materials, allowing for precise adjustment of cutting inserts without damaging the tool cartridge or carrier body, and facilitates a two-stage adjustment process for the cutting edges.
Implementation Method 1
at least one adjusting wedge (51, 52, 53) which are each arranged to be displaceable along a defined displacement axis (34a, 35a, 36a) in a guide (34, 35, 36) formed on the tool cartridge (3) and via a wedge surface (51b, 52b, 53b) with a respectively opposite side wall (22b, 22c) of the tool cartridge seat (22) interact
Implementation Method 2
The wedge surfaces (51b, 52b, 53b) of the adjusting wedges (51, 52, 53) and the respectively opposite side walls (22b, 22c) of the tool cartridge seat (22) form a wedge mechanism that enables fine adjustment of the position of the tool cartridge (3)

AI summary
The invention relates to a tool cassette (3) with a holding pocket for holding a cutter insert (4), which tool cassette can be fixed in an adjustable position in a tool cassette seat (22) of a carrier body (2) for a cutting tool (1) by means of a clamping screw (6) inserted through a bore (31) passing through the tool cassette (3). The tool cassette (3) has an integrated adjustment device (5) for adjusting the radial position, the axial position and/or the angular position of the tool cassette (3) relative to a central longitudinal axis (11) of the carrier body (2) by cooperating with one or more side walls (22b, 22c) of the carrier body (2) that delimit the tool cassette seat (22).
