Abstract

The invention relates to a machine tool for machining a large gear in a spiral bevel gear pair and further relates to the machine tool of the large gear of the spiral bevel gear pair used for an automobile drive axle. Three sets of an X-axis guide rail, a Y-axis guide rail and a Z-axis guide rail which are vertical to each other are arranged on the top face of the machine tool body, and an X-axis slide table, a Y-axis slide table and a Z-axis slide table which move along corresponding guide rails under the action of a driving mechanism are arranged on the X-axis guide rail, the Y-axis guide rail and the Z-axis guide rail. A cutter plate or a grinding wheel is arranged at the bottom of the Z-axis slide table, and a shaft C capable of driving a machined workpiece to rotate is arranged in the Z-axis slide table. The machine tool further comprises a shaft B which penetrates through the front end face and the rear end face of the machine tool body. The front end of the shaft B is connected with a workpiece box, and the rear end of the shaft B is provided with a rotating mechanism driving the shaft to rotate B. A shaft A driving the machined workpiece to rotate is arranged in the workpiece box, and the shaft A is vertical to the shaft B. Compared with an existing device, the machine tool for machining the large gear in the spiral bevel gear pair has the advantages of being simple in structure, economic in cost, convenient to install and detach, capable of easily discharging chips and the like, and is particularly suitable for dry cutting and high-efficiency machining.

Description

technical field [0001] The invention relates to a machine tool for processing large gears in spiral bevel gear pairs, and further refers to a machine tool for processing large gears in spiral bevel gear pairs used on automobile drive axles. Background technique [0002] Most of the spiral bevel gears used in automobile drive axles are hypoid gears with relatively large transmission ratio. The pitch angle of the large gear is generally between 70°~80°, and the shape of the tooth surface of the gear tooth is very close to the cutting surface of the production wheel. In order to improve the processing efficiency, the forming method is used instead of generating motion. At present, the large gears of the automobile drive axle are processed on the general-purpose CNC gear milling and grinding machines with six axes and five linkages. It has the following disadvantages: [0003] 1. When the large gear of the automobile drive axle is processed by the generation method, only four-a...
