gear milling machine

Abstract

The invention discloses a gear milling machine, which relates to a gear processing equipment, and aims to solve the technical problem that the chamfering of the tooth top of the gear formed by the milling cutter needs to be reprocessed and the efficiency is low in the prior art, and the main points of the technical solution It includes a body, a column arranged on the body, and a cutter body that is rotatably arranged on the column. The column is provided with a fixed gap for the installation of the cutter body, and a positioning shaft is rotated on the side wall of the fixed gap. Bosses are provided on both sides of the body facing away from each other, mounting holes for the positioning shaft to pass are provided on the side walls of the bosses, and cutting teeth are provided at the edges of the cutter body facing away from both sides For the cutting knife group of the groove, the chamfering knife is provided on both sides of the boss away from each other; in this way, the two processing can be combined into one processing, which improves the work efficiency; and the precision of the gear meshing can also be improved.

Description

technical field [0001] The present invention relates to a gear machining equipment, more specifically, it relates to a gear milling machine. Background technique [0002] Gear milling machine is the most widely used machine tool in gear processing machine tools, that is, the tooth surface of gear or rack can be processed by using milling cutter or milling cutter disc according to the forming method or generating method, and straight teeth, helical gears can be cut on the gear milling machine. Toothed cylindrical gears can also process worm gears, sprockets, etc. Since the milling cutter mainly rotates, supplemented by the feed motion of the table or milling head, the workpiece can obtain the required processing surface; its main components include the machine body , table, column, milling cutter, drive unit and cooling unit. [0003] The Chinese patent with the authorized announcement number CN205816976U discloses a gear milling machine with a milling cutter lifting device,...

AI Technical Summary

Problems solved by technology

[0003] The Chinese patent with the authorized announcement number CN205816976U discloses a gear milling machine with a milling cutter lifting device, which solves the technical problems of the existing gear milling machine that the cutter head is easily damaged, the product quality is low, and the production cost is high. The base, the base is provided with a column, the column is equipped with a milling cutter lifting device and a milling cutter rotating device, the milling cutter lifting device is equipped with a lifting motor, a slide rail and a lifting plate, the lifting motor and the slide rail are all set on the column, and the lifting plate There is a slideway, the slideway is matched with the slide rail, and the lifting motor is connected with the lifting plate

[0004] When using the gear milling machine in the prior art, the milling cutter mills the workpiece, and the disc drives the workpiece to rotate, and the milling cutter continues to mill the workpiece. However, in practical applications, the milling cutter mills from top to bottom to form Tooth groove, the top of the tooth near the two sides of the tooth groove produces relatively sharp edges. At this time, after the gear needs to be disassembled, the sharp edge of the tooth top should be chamfered again by a gear chamfering machine, which is time-consuming and laborious, and needs to be improved
