AI Technical Summary
Technical Problem
The lack of lateral restraint when the existing milling cutter inserts are installed horizontally causes slippage or wobbling, shortening the life of the inserts.
Method used
A spiral groove is made on the outer surface of the blade body, and a V-groove is set at its bottom end. Combined with a V-block and a locking bolt, the first and second blades are positioned and installed to prevent lateral displacement. At the same time, the design of the blade holder and the mounting sleeve, along with the worm gear, worm wheel and locking block structure, facilitates installation and disassembly.
Benefits of technology
It improves the lifespan of the blade, prevents loosening and lateral displacement, and simplifies the installation and removal process of the tool holder.

Abstract
This application relates to a milling cutter insert mounting structure and a milling cutter, belonging to the technical field of milling cutter insert mounting. It includes a cutter body with two helical grooves on its outer surface. Each helical groove has a V-groove at its bottom end. A first insert and a second insert are mounted below the cutter body. This application uses components such as V-grooves and V-blocks. A V-groove is formed at the bottom end of the helical groove, and a V-block is installed on the side of the first and second inserts near the cutter body. The fit between the V-block and the V-groove allows the first and second inserts to be positioned and installed. A locking bolt is used to connect them to the cutter body, fixing the first and second inserts. After fixing, the fit between the V-groove and the V-block prevents lateral displacement of the first and second inserts during operation, thus preventing loosening and extending their service life.
