Abstract
The utility model relates to a combined milling cutter, which comprises a blade. The circumferential edge of the blade is provided with a plurality of cutter teeth. The combined milling cutter is characterized in that: it also includes a columnar cutter handle perpendicular to the plane of the blade, the center of the blade is provided with a mounting hole, and the blade is sleeved on the cutter handle through the mounting hole so as to achieve flexible connection with the cutter handle. When the blade is worn, it can be dismantled easily and repaired or replaced individually, thereby providing greater convenience, improving the work efficiency, and reducing the cost. The blade and the cutter handle can achieve simple threaded connection, or a locating piece can be added, or the blade can be fixed on the cutter handle directly by the locating piece. The structure is simple and stable, and the use is safe. Also, the blade can be prevented from making circumferential rotation relative to the cutter handle through cooperation of concave-convex patterns, and relative movement of the blade and the cutter handle can be prevented during high-speed rotation work of the blade.

For achieving the above object, the technical solution adopted in the utility model is: a kind of combination type milling cutter, comprise a blade, the circumferential edge of blade is provided with some cutters tooth, it is characterized in that: also comprise the column handle of a knife that vertical described blade plane arranges, installing hole is offered at described blade middle part, and by installing hole, is set on described handle of a knife, with described handle of a knife, is flexibly connected.
Preferably, described installing hole inside is provided with internal thread, and handle of a knife is provided with the external screw thread that matches with described internal thread, and blade and handle of a knife are connected by described internal and external screw thread.
Preferably, described handle of a knife comprises main body and axially is located at the boss of main body one end, the radial dimension of described boss is less than the radial dimension of described main body, and described blade sleeve is located on boss, and the free end of boss is connected with the keeper of the described blade in location axial location on boss.
Preferably, described handle of a knife comprises main body and axially is located at the boss of main body one end, the radial dimension of described boss is less than the radial dimension of described main body, and described blade sleeve is located on boss, and the free end of boss is connected with the keeper of the described blade in location axial location on boss.
Preferably, described boss outer surface is provided with some grooves of circumferential distribution, and described groove is strip, along boss, extends axially; The inner surface of described installing hole is provided with some projections of circumferential distribution, and described projection is strip, along blade, extends axially, and described blade is located on boss by the engage sleeves of projection and groove.
Preferably, described boss outer surface is provided with some projections of circumferential distribution, and described projection is strip, along boss, extends axially; The inner surface of described installing hole is provided with some grooves of circumferential distribution, and described groove is strip, along blade, extends axially, and described blade is located on boss by the engage sleeves of projection and groove.
Preferably, the axial length of described main body be the boss axial length 3.2-3.6 doubly.
The utility model has solved the defect that exists in the background technology, combination type milling cutter of the present utility model, and blade and handle of a knife are flexibly connected, and during blade abrasion, can easily remove separately and repair or replace.Convenient, and can increase work efficiency, reduce costs.Blade and handle of a knife can simply be threaded, and also can install keeper additional, perhaps directly with the keeper fixed blade on handle of a knife, simple in structure, stable, use safety.Can also prevent that by the cooperation of ridge design blade from circumferentially rotating with respect to handle of a knife, produce relative motion while preventing the work of blade high-speed rotation and between handle of a knife.
