Technical Field

The invention relates to the field of milling cutters, in particular to a high-speed cutting cutter for numerical control milling of aluminum alloy.

Technical Field

The existing milling cutter cannot perform quick cutting processing on the curved surface of an aluminum alloy concave groove, the efficiency is low, the cutting process is poor, the processing and cutting speed can only reach 200-300 m/min, and an integrated cutter body or a welded blade is used for processing such workpieces, so that the cutting stability is insufficient, the blade is poor in rigidity and easy to damage, and the replaceability is not available, so that the problems of high production cost and low product percent of pass are caused.

disclosure of Invention

The invention mainly aims to provide a high-speed cutting tool for numerical control milling of aluminum alloy, which can effectively solve the problems in the background technology.

In order to achieve the purpose, the invention adopts the technical scheme that:

The utility model provides a high-speed cutting tool of aluminum alloy numerical control milling process, includes blade and handle of a knife, blade center department sets up location well shaft hole, and this location well shaft hole is fixed all around and has seted up the installation through-hole, the handle of a knife becomes cylindricly, and the fixed reference column that is equipped with in one end axis department of handle of a knife, this reference column fixed set up all around with blade installation through-hole assorted screw hole, the location axis hole ring cover that the blade was equipped with is on the reference column that the handle of a knife was equipped with, and the blade uses locking screw fixed mounting on the handle of a knife, balanced adjustment screw hole has been seted up to handle of a knife side anchor ring, and installation location core shaft hole has been seted up to handle of a knife axis department, and the interior cold water through-hole has been seted up to.

Furthermore, positioning through holes are formed in two sides of the positioning center shaft hole formed in the blade, and the central axis of each positioning through hole and the central axis of each threaded hole are located on the same center circle.

Furthermore, positioning pieces matched with the blade positioning through holes are fixedly arranged on two sides of a positioning column arranged on the cutter handle.

Furthermore, the fastening screw comprises a fixing stud and a fixing head, chamfers are arranged at two ends of the fixing stud, the fixing head extends from one end of the fixing stud, the fixing head is in a cylindrical step shape, a hexagonal counter bore is formed in the end face of the end with the larger outer diameter of the fixing head, a cooling through hole is formed in the middle shaft of the fixing stud, and the cooling counter bore is fixedly formed in the end, far away from the fixing head, of the cooling through hole.

Compared with the prior art, the invention has the beneficial effects that:

The invention carries out new design on the blade mounting structure, improves the cutting efficiency of the curved surface processing of the aluminum alloy concave groove, has simple structure and is convenient for replacing the blade.
