Indexable forming gear milling cutter head device

Abstract

The invention belongs to the field of machining and relates to an indexable forming gear milling cutter head device which comprises a milling cutter head base body, milling cutter blades and chip grooves, wherein the milling cutter blades are fixedly connected with a milling cutter head through inner hexagon screws respectively; and each milling cutter blade comprises a top-edge milling blade and a side-edge milling blade which are closely arranged and share one blade groove, wherein the top-edge milling blade is a rectangular blade and accounts for 2 / 3 of the total area of the blade groove, and the side-edge milling blade is square and occupies the rest area of the blade groove. By using the indexable forming gear milling cutter head device disclosed by the invention, the process manufacturing flow of the milling cutter head is optimized, the obtained gear milling cutter head is of a compact structure, and thus the strength of the milling cutter head base body is improved; 24 groups of blades are arranged on the two side surfaces of the milling cutter head base body at equal intervals in a staggered manner, so that the reasonability and the stability of the milling process are ensured; and the chip grooves are close to the corresponding blade grooves and are designed in a smooth fluid curve mode, so that cuttings flow out rapidly and smoothly so as to take away a part of cutting heat, the cutting process is more accurate, and the machining requirement of a gear is met.

Description

technical field [0001] The invention relates to the field of mechanical processing, in particular to a milling cutter, in particular to a shaped milling cutterhead, which belongs to high-efficiency roughing milling cutters. Background technique [0002] In recent years, with my country's transition from a big manufacturing country to a powerful manufacturing country, my country's manufacturing level has been continuously improved, and R&D investment in the machinery industry has continued to increase. How to improve the milling level and milling efficiency of gears has become the focus of today's society. Moreover, during the milling process, the tool will also be damaged due to strength problems, which will not only slow down the manufacturing process of the gear, but also bring safety hazards to the workers on the production line. Therefore, the design of the milling tool has become a a problem that urgently needs to be resolved. At the same time, how to reduce the manufact...
