Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current milling cutter inserts face issues with poor positioning and machining deviation due to clamping-based positioning, leading to reduced reliability and limited efficiency, and the single tip design is prone to abrasion, affecting working stability and the ability to increase the number of inserts.
Innovation Solution
A vertically-mounted milling cutter insert with a double-cutter tips structure and a bent-plane positioning system that prevents abrasion, allowing for accurate and stable positioning of two cutter tips, and a multitooth milling cutter design with a dynamic balance adjusting screw and mounting and positioning screw set for enhanced precision and reliability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single tip design is used with clamping positioning, then the structure is simple, but the clamped site gets abraded and working reliability decreases
Solution Approach 1:
The insert base is divided into multiple functional zones: a clamping region for secure mounting, a positioning region with bent-plane structures for precise location, and a cutter tip mounting region. This segmentation allows the clamping force to be applied without directly abrading the positioning surfaces, resolving the contradiction between simple structure and reliable operation.
Solution Approach 2:
The bent-plane positioning structures act as intermediary elements between the clamping mechanism and the cutter tip mounting location. These positioning structures transfer and stabilize the insert's position without being directly involved in the clamping action, preventing abrasion while maintaining reliability.
2Reliability
If clamping positioning mode is used, then the insert can be securely mounted, but the number of inserts that can be mounted is limited and machining efficiency cannot be further improved
Solution Approach 1:
The insert base design with standardized bent-plane positioning structures and multiple cutter tip options creates a universal mounting system. Different cutter tip configurations can be mounted on the same base using the same positioning mechanism, allowing increased insert capacity without compromising mounting reliability, thus improving machining efficiency.
3Device complexity
If traditional single structure base is used, then the structure is simple, but positioning accuracy deteriorates and machining deviation occurs during long working time and high working frequency
Solution Approach 1:
The base structure implements local quality by providing different structural characteristics in different regions: the bent-plane positioning structures offer high precision and stability in the positioning region, while other parts of the base maintain simplicity. This localized enhancement of positioning accuracy without overall structural complexity resolves the contradiction between simple structure and precision maintenance during extended operation.

AI summary
The present invention discloses a vertically-mounted milling cutter insert and a multitooth milling cutter, wherein the vertically-mounted milling cutter insert comprises a insert base and a cutter tip unit, the insert base is set with a mounting hole for mounting the vertically-mounted milling cutter insert onto the milling cutter wheel, and the cutter tip unit is mounted on the insert base, and the cutter tip unit has a double-cutter tip structure. In the invention, the vertically-mounted milling cutter insert is positioned via the fitting between a bent-plane structure in the vertically-mounted milling cutter insert and a positioning structure in the milling cutter wheel, and the bent-plane structure will not be abraded in use. Because the bent-plane structure will not be abraded, reliable positioning may be guaranteed when two cutter tips are used.
