The problems that the traditional gear milling cutter is too high in machining cost and cannot efficiently machine and harden the processed tooth surface are solved. The utility model discloses an indexable ceramic blade is the multiunit, and every group is two, sets up from top to bottom, and the cutter body is overall structure, is equipped with sword groove and briquetting groove on the cutter body, and briquetting inslot opens has the screw, and indexable ceramic blade arranges the sword inslot in by blade briquetting and stud through the screw fastening on the cutter body, and staggered arrangement is controlled on the circumference of cutter body about indexable ceramic blade. The utility model discloses simple structure, the installation is reliable, convenient loading and unloading, and the precision is high, full play high-speed, high-efficient mill the advantage of tooth machine and gear hobbing machine, improved the machining efficiency of hard tooth face gear greatly.

Description

Integral hard tooth surface indexable gear finish milling cutter

Technical Field

The utility model relates to a gear machining cutter, concretely relates to but whole hard flank of tooth transposition gear finish milling cutter.

Background

At present, after gear tooth surface hardening treatment (nitriding, carburizing and quenching and the like), the allowance of a tooth surface is still large for gear grinding, but the rough machining in the prior art has a lot of uncertainty, so the finishing allowance of the tooth surface cannot be remained too small, so the cutter which can effectively remove the allowance after the tooth surface is hardened is particularly important, the machining cost of the current hard alloy blade is too high, and an indexable gear finishing cutter using a ceramic blade is developed for solving the problem.

SUMMERY OF THE UTILITY MODEL

The utility model discloses a solve traditional milling teeth cutter processing cost too high, can not the efficient problem of the flank of tooth after the work hardening treatment, provide a whole hard flank of tooth indexable gear finish milling cutter, the technical scheme who solves this problem as follows:

the utility model discloses a whole profile milling cutter of hard tooth face transposition gear comprises cutter body, transposition ceramic blade, blade briquetting and the fixed double-end screw of blade, but transposition ceramic blade is the multiunit, and every group is a plurality of, and bilateral symmetry sets up, and the cutter body is overall structure, is equipped with sword groove and briquetting groove on the cutter body, but the briquetting inslot is opened there is the screw, but transposition ceramic blade arranges the sword inslot in by blade briquetting and double-end screw through the screw fastening on the cutter body, but transposition ceramic blade left and right sides staggered arrangement on the outer circumference of cutter body, constitute profile milling cutter of hard tooth face transposition gear.

The utility model relates to a but whole hard flank of tooth transposition gear finish milling cutter, simple structure, the installation is reliable, convenient loading and unloading, and the precision is high, full play high-speed high-efficient mill tooth machine and gear hobbing machine's advantage, improved the machining efficiency of hard flank of tooth gear greatly.
