Abstract

A disciform gear milling cutter including a facing cutter, a milling insert and a chip pocket is disclosed, wherein the milling insert is fixed in the cutting area of the facing cutter through a housing screw; the milling insert comprises a top edge milling insert and a side edge milling insert, the cutting edge of the top edge milling insert adopts the positive rake angle design to be equi-spaced on the end plane of the periphery of the facing cutter, the angle of the positive rake angle is 3-4 degree, the side edge milling insert is arrayed in cutting areas at two sides of the facing cutter corresponding to the relevant top edge milling insert, and the cutting surfaces formed by the cutting edges of the side edge milling insert that are arranged in the adjacent front and back rows of the cutting area of the facing cutter complement each other. The utility model has advantages of that the milling insert is fixed on the facing cutter according to the positive rake angle design, the cutter feeding speed in the axial direction is high; the top edge milling insert make the dedendum of the processed gear wheel transit smoothly; the cutting surfaces formed by the cutting edges of the side edge milling insert in the adjacent front and back rows complement each other, so the cutting dead angle is avoided; the milling insert adopts the indexable insert, which is convenient for changing and can extend the service life of a single milling insert.

Description

The plate-like gear milling cutter
Technical field
The utility model relates to a kind of milling cutter, especially a kind of plate-like gear milling cutter.
Background technology
Increase along with the wind power generation gear case demand, the High-speed machining of large module gear is brought into schedule, but rely on the working ability of common or external High-efficient Hobbing Cutter, pinion cutter, can not satisfy industrial requirement far away, and the process-cycle and the manufacturing cost of the manufacturing cycle of cutter and the direct restraining gear case of cutter consumption.With the exception of this, according to common pinion cutter, adopt Principles of Gear Connection processing, the arc radius of tooth root constantly changes along with the loss of cutter, causes strength of gear teeth designing and calculating and actual manufacturing tolerance, brings potential hidden danger to the gear-box quality.
Summary of the invention
The purpose of this utility model is: at the problem that large module gear exists in Gear Processing, propose a kind of new plate-like gear milling cutter.
The purpose of this utility model is achieved in that a kind of plate-like gear milling cutter, comprises facing cutter, cutter blade and chip pocket, it is characterized in that: cutter blade is fixed in the cutting region of facing cutter by housing screw; Described cutter blade comprises top blade milling cutter sheet and side edge cutter blade, wherein, the cutting edge of top blade milling cutter sheet adopts the positive rake angle design evenly to place the outer rim end face of facing cutter, the angle of its positive rake angle is 3~4 degree, the side edge cutter blade is arranged in the cutting region of the both sides of facing cutter, and with the corresponding arrangement of corresponding top blade milling cutter sheet, be arranged in the cutting face complementation that the side edge cutter blade cutting edge among the adjacent forward and backward row of facing cutter cutting region forms.
In the utility model: described cutter blade is the indexable insert tip, throw away tip that carbide alloy is made.Described indexable insert tip, throw away tip is the peripheral rectangular rigid alloy blade that is equipped with cutting edge, and blade central authorities are provided with the housing screw fixing hole.
In the utility model: described facing cutter outer rim end face is at least evenly installed 12 top blade milling cutter sheets.
Advantage of the present utility model is: cutter blade designs the cutting region that is fixed in facing cutter by housing screw according to positive rake angle, and iron filings thickness clearance is big, thereby can obtain higher axial feeding speed; Top blade milling cutter sheet can guarantee the tooth root rounding off of processed gear, makes it obtain bigger carrying and anti-fatigue performance; Be arranged in the cutting face that the cutting edge of adjacent forward and backward row's side edge cutter blade of the both sides of facing cutter forms and form complementation, make machined surface not stay the cutting dead angle; The indexable insert tip, throw away tip that cutter blade adopts carbide alloy to make, it is convenient not only to change cutter blade, and can prolong the service life of single cutter blade.
