Abstract

The invention relates to a rotor milling cutter and a blade fixing structure, and relates to the technical field of metal machining. The rotor milling cutter and the blade fixing structure each comprise a cutter body (1), blades (2) and pressing blocks, wherein a plurality of blade grooves are formed in the cutter body (1), a cushion block (10) is mounted on each blade groove, pressing block grooves (16) used for mounting the pressing blocks are formed beside the blade grooves, the blades (2) are fixed to the cushion blocks (10) through the pressing blocks to form a complete rotor milling cutter cutting edge (11), adjusting block grooves (13) are formed in blade positioning surfaces (22) of the blades (2), adjusting blocks (5) used for adjusting the angles of the blades (2) are mounted on the adjusting block grooves (13), certain included angles alpha are formed between the contact surfaces between the blades (2) and the cushion blocks (10) and the axial directions of the blades (2), and certain included angles beta are formed between the contact surfaces between the blades (2) and the cushion blocks (10) and the radial directions of the blades (2). According to the rotor milling cutter and the blade fixing structure, it can be guaranteed that the blades are not prone to loosen in the machining process, and the blades can further be finely adjusted.
