Abstract
The utility model discloses a staggered tooth combined milling cutter, relates to a combined milling cutter, and aims at solving the problems of a conventional combined milling cutter that the stability in cutting is insufficient when in use, the axial resistance is relatively high, and the service life of the cutter is influenced. The milling cutter consists of a left milling cutter and a right milling cutter, wherein circumferential teeth in an outer circle of the left milling cutter have left spiral angles of 15 degrees, and the circumferential teeth in the outer circle of the right milling cutter have right spiral angles of 15 degrees; circular bosses are arranged in the center positions of two attached end surfaces of the left milling cutter and the right milling cutter; inner holes in match with cutter bars are formed in the circular bosses; key grooves for placing transmission keys are placed in the inner holes; four bosses are uniformly arranged at the side edges of teeth in two attached end surfaces of the left milling cutter and the right milling cutter along the circumference; a concave groove in match with each boss is formed between every two bosses; and the left milling cutter is matched with the right milling cutter through the bosses and the concave grooves. The staggered tooth combined milling cutter is applied to roughly mill an inner rear arc-shaped line on a blade.
Description
Technical field
The utility model relates to a kind of cutter block.
Background technology
Cutter block is the dedicated tool of rough milling back of the body camber line in the blade.Former is monolithic construction with cutter owing to can't process the zigzag tooth structure, during use cutting steady inadequately, axially drag is bigger, influences cutter life, for this improves this cutter structure, has developed the zigzag tooth cutter block.
The utility model content
The purpose of this utility model provides a kind of zigzag tooth cutter block, when using to solve present cutter block cutting steady inadequately, axially drag is bigger, influences the problem of cutter life.
The utility model is to solve the problems of the technologies described above the technical scheme of taking to be: milling cutter is made of left milling cutter and right milling cutter, left side milling cutter cylindrical circumferential teeth adopts left-handed helical angle, left-handed helical angle is 15 °, right milling cutter cylindrical circumferential teeth adopts the right hand helix angle, the right hand helix angle is 15 °, two end face center positions that left side milling cutter and right milling cutter fit are equipped with round boss, have the endoporus that matches with knife bar in the round boss, endoporus is provided with the keyway of placing driving key, the edge of the tooth of two end faces that left side milling cutter and right milling cutter fit respectively is uniformly distributed along the circumference and is provided with four boss, form groove between per two boss, this groove and boss are complementary, and left milling cutter and right milling cutter interlock by boss and groove and cooperatively interact.
The utlity model has following beneficial effect: the utility model is rough milled when carrying on the back the camber line in the blade, because adopt the zigzag tooth structure, the axial drag of left milling cutter and right milling cutter is cancelled out each other, make stable cutting, vibration when having reduced machining has greatly improved cutter life.
