Clamping Ring Milling Cutter for Fast Insert Changes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing milling tool cutters require substantial time and resources to attach and detach cutting inserts due to the need for separate fastening and detaching of each insert, leading to increased costs.
Innovation Solution
A milling tool cutter design featuring a tool body with circumferentially arranged pockets, clamping studs, a clamping ring, and a detachable fastening member that allows for simultaneous attachment and detachment of multiple cutting inserts by fixing the clamping ring to the tool body with a threaded bolt, enabling quick clamping and de-clamping.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate fasteners are used to attach each cutting insert individually, then each cutting insert can be securely attached to its pocket, but substantial time and resources are required to attach and detach each insert separately
Solution Approach 1:
Multiple individual fastening operations are merged into a single collective fastening operation. The clamping ring with multiple clamping studs combines the function of multiple separate fasteners, allowing all cutting inserts to be attached or detached simultaneously by tightening or loosening one set of fasteners that secure the clamping ring, rather than operating on each insert individually
2Reliability
If separate fasteners are used for each cutting insert, then each insert can be independently secured, but the process requires substantial resources and increases cost
Solution Approach 1:
The fastening system merges multiple individual fastening mechanisms into a single integrated clamping ring assembly. This reduces the total number of fasteners required, simplifies the attachment process, and reduces operational costs by enabling simultaneous fastening of all inserts through a unified mechanism rather than requiring multiple separate fastening operations
3Productivity
If multiple cutting inserts are attached simultaneously using a clamping ring, then time and resources are reduced, but the device structure becomes more complex
Solution Approach 1:
The clamping ring serves multiple functions simultaneously: it acts as a structural support element, a fastening mechanism, and a positioning device for multiple cutting inserts. By designing the clamping ring with integrated clamping studs and fastening holes, a single component performs what would otherwise require multiple separate components, thereby reducing overall system complexity while maintaining the ability to attach multiple inserts simultaneously

AI summary
A milling tool cutter includes a tool body, a plurality of cutting inserts, a plurality of clamping studs, a clamping ring, and a detachable fastening member. The tool body has a plurality of pockets disposed circumferentially around the tool body. Each of the cutting inserts is disposed in one of the respective pockets. Each of the clamping studs is attached to one of the respective cutting inserts. The clamping ring is disposed within the tool body. The clamping ring includes a face surface, a seating surface, and a circumferential outer surface extending between the face surface and the seating surface. The seating surface sits against the plurality of clamping studs. The detachable fastening member is disposed in an attached state fixedly attaching the clamping ring to the tool body causing the clamping studs and their respective cutting inserts to be fixedly attached to the tool body.
