Planetary milling cutter

Abstract

The invention discloses a planetary milling cutter, which is mainly applied to high-efficiency milling for planes during machining. The planetary milling cutter comprises a main shaft box 1, a rotating main shaft 2, a positioning central shaft 3, fastening screws 4, a central bracket 5, bracket bolts 6, circular nuts 7, branch milling cutter shafts 8, planetary sleeve shafts 9, gland screws 10, bearing glands 11, oil seals 12, bearings 13, a rotating cutter disk 14, bracket inner oil seals 15, bolts 16, cover boards 17 and bracket outer oil seals 18, wherein the rotating cutter disk 14 rotates continuously under the driving of the rotating main shaft 2 which rotates continuously; the branch milling cutter shafts 8 rotate around the axis of the rotating main shaft 2 and also rotate around the respective axes; and the rotating machining motion of the planetary milling cutter is synthesized by the rotating motion of the rotating cutter disk 14 and the rotating motions of the branch milling cutter shafts 8. According to the planetary milling cutter, cutting force can be effectively reduced, cutting heat can be reduced, the durability of the cutter is improved, and the plane milling efficiency is improved.

Description

Technical field: [0001] The invention relates to a planetary milling cutter, which is mainly used for high-efficiency milling of planes in mechanical processing. Background technique: [0002] With the development of the mechanical processing industry, the requirements for processing efficiency are getting higher and higher. Improving the efficiency of processing, especially on the basis of the original mechanical processing equipment, is a subject that people have been studying. The traditional face milling cutter is a face milling cutter or an end milling cutter. The diameter of the face milling cutter is larger, and the area of ​​the milling plane is larger at one time. However, because of the straight edge cutting, the milling force is larger than that of the spiral edge cutting, which limits The selection of large cutting amount affects the processing efficiency.

The traditional face milling cutter is a face milling cutter or an end milling cutter. The diameter of the face milling cutter is larger, and the area of ​​the milling plane is larger at one time. However, because of the straight edge cutting, the milling force is larger than that of the spiral edge cutting, which limits The selection of large cutting amount affects the processing efficiency

Although the end mill is cutting with a helical edge, the diameter cannot be made very large considering factors such as cost and manufacturing, which will also affect the processing efficiency, especially the processing efficiency of large planes.
