The utility model discloses combination formula screw rod engine spiral rotor processing milling cutter comprises cutter body, blade, voussoir, left end clamping ring, right-hand member clamping ring.
The cutter body is the disc, it has shaft hole and keyway to open at the cutter body center, the outer marginal part cross sectional shape of cutter body corresponds with blade profile shape, a plurality of blade mounting grooves have been seted up to circumference evenly distributed at cutter body outer marginal part, settle the blade in one side of blade mounting groove, settle the voussoir at the opposite side of blade mounting groove, the voussoir carries out radial fastening connection with the cutter body through voussoir cotter screw, and the voussoir extrudees the fastening and fixes the blade, left end clamping ring and right-hand member clamping ring are arranged in the terminal surface about the cutter body respectively, left end clamping ring and right-hand member clamping ring pass through screw and cutter body fixed connection, and left end clamping ring and right-hand member clamping ring carry out axial spacing fixed to the blade.
The utility model discloses screw rod engine spiral rotor processing milling cutter, including positive spiral rotor processing milling cutter and negative spiral rotor processing milling cutter. The male rotor milling cutter differs from the rotor milling cutter only in the shape of the edge profile of the insert. The blade edge profile shape of the blade is designed and formed according to the parameters of the SRM rotor profile.
The utility model discloses milling cutter integrated configuration, low in manufacturing cost, only the blade adopts special steel of cutter and thermal treatment manufacturing, and convenient for production is with low costs.
The utility model discloses modular milling cutter has integral milling cutter relatively and can evenly distributed set up more cutting edges (blades) on the circumference, and blade is in large quantity, can effectively improve milling cutter's machining efficiency and precision.
When a certain blade (cutting edge) is damaged or the whole blade is worn to a certain degree, the combined milling cutter can simply and conveniently replace the blade; after the blade with the worn blade is sharpened again, the blade can be installed again for continuous use, the whole cutter cannot be scrapped, and the economical efficiency is good.
