Embodiment Construction

[0031] like Figure 4 Among them, a forming and generating gear milling machine includes a machine base 4, on which a rotary table 3 for supporting a workpiece 1 is arranged, and the rotary table 3 drives the workpiece 1 to achieve precise indexing.

[0032] The base 4 is also equipped with an X-direction sliding seat 5 through a slide rail, and the movement of the X-direction sliding seat 5 can realize different full-tooth deep cuttings by controlling the feed position of the X coordinate according to different modulus.

[0033] The X-direction slide seat 5 is fixedly connected with a column 6, and the column 6 is installed with a Y-direction slide seat 7 through a slide rail, and a Z-direction slide seat 9 is installed on the Y-direction slide seat 7 through a slide rail. Y coordinate movement. This movement enables an infeed in the direction of the tooth width for cogging.

[0034] The cutter assembly is installed on the Z-direction slide seat 9. The Z-coordinate movemen...

Abstract

The invention discloses a forming and generating gear milling machine and a processing method. The forming and generating gear milling machine comprises an engine base, wherein the engine base is provided with a rotary workbench used for supporting a workpiece; the engine base is also provided with an X-direction sliding seat by a sliding rail; the X-direction sliding seat is provided with a Y-direction sliding seat by a sliding rail; the Y-direction sliding seat is provided with a Z-direction sliding seat by a sliding rail; and a cutter assembly is installed on the Z-direction sliding seat. The processing method for milling a gear by the equipment comprises the following steps: a cutter rotates to form cutting movement to the workpiece; in the forming processing state, after most metal removal amount is removed, the Z-direction sliding seat drives the cutter to axially move; and the generating processing of a single-tooth groove is jointly finished by the axial movement of the cutter and the rotation of the workpiece. According to the equipment and the method, the cutter with a better generality than generating processing can be used, and a constraint condition of modulus is omitted in two items of necessary conditions of the original generating cutter, i.e. modulus and a pressure angle. Under the condition of the same pressure angle, the same cutter can be used for processing gears of different modulus.

Description

technical field [0001] The invention relates to the field of hobbing and milling gear processing, in particular to a forming and generating gear milling machine and a processing method. Background technique [0002] At present, there are only two types of processing methods for cylindrical external gears: one is generating processing, using gear hobbing machines or gear shaping machines. The gear hobbing machine uses the helix angle of the hob cutter tooth to change the axial position of the cutter tooth when the tool is continuously rotated to achieve generating motion with the rotation of the workpiece; the gear shaping machine directly rotates the tool and the workpiece according to the gear ratio to achieve generating motion. . Another type is forming processing, which is the intermittent indexing forming cutter gear milling machine that has appeared in recent years. [0003] The efficiency of forming processing is much higher than that of generative machining, and the...
