[0023] The embodiments of the present application will be described in detail with specific embodiments, and other advantages and effects of the present application can be easily understood by those skilled in the art from the disclosure. Although the description of the present application will be introduced together with the preferred embodiments, this does not mean that the features of the present application are limited to the embodiments. On the contrary, the purpose of introducing the present application with the embodiments is to cover other options or modifications that can be extended based on the claims of the present application. In order to provide a deep understanding of the present application, many specific details will be included in the following description.

[0024] Reference Figs. 1-3 A deburring disc cutter of a gear hobbing machine, comprising a cutter head 1, wherein a groove 4 is arranged on the cutter head 1, a first cutting edge 2 and a second cutting edge 3 are arranged on the cutter head 1 in the circumferential direction, the first cutting edge 2 is arranged on the outer circumferential surface of the cutter head 1, and the second cutting edge 3 is arranged at the connection between the groove 4 and the cutter head 1, that is, the distance between the first cutting edge 2 and the axis of the cutter head 1 is greater than the distance between the second cutting edge 3 and the axis of the cutter head 1. In the process of deburring the gear 6 by using the disc cutter, the gear 6 rotates and moves to the cutter head 1, first contacts the first cutting edge 2, and the first cutting edge 2 sequentially performs primary cutting on the burrs on the lower end surface of the gear 6. The gear 6 continues to move and contacts the second cutting edge 3, and the second cutting edge 3 performs secondary cutting on the burrs on the lower end surface of the gear 6. After two times of cutting, the burrs on the lower end surface of the gear 6 are effectively removed.

[0025] The angle between the first cutting edge 2 and the vertical direction is 15 degrees, and the angle between the second cutting edge 3 and the vertical direction is 20 degrees. In the process of deburring the gear 6, the first cutting edge 2 is used for primary processing, so that the first cutting edge 2 is more likely to be abraded and passivated. The smaller angle of the first cutting edge 2 can make the first cutting edge 2 more resistant to impact, thereby improving the service life of the first cutting edge 2. The second cutting edge 3 is used for secondary processing, and the larger angle of the second cutting edge 3 makes the second cutting edge 3 sharper, which can ensure the cutting processing quality and improve the deburring effect and efficiency.

[0026] The center of the cutter head 1 is provided with a through hole 7, the through hole 7 is provided with a connecting shaft 8, the connecting shaft 8 is fixed on a gear hobbing machine, the cutter head 1 is connected with the gear hobbing machine through the connecting shaft 8, the gear is rotated in the process of being cut by a hobbing cutter of the gear hobbing machine, so that the relative movement between the cutter head 1 and the gear is generated, thereby realizing the sequential cutting of the first cutting edge 2 and the second cutting edge 3 on the cutter head 1 to the gear burr. When the cutting edge of a certain area on the cutter head 1 is dull, only one angle of the cutter head 1 needs to be rotated to generate a new cutting edge to continue effective cutting, thereby improving the overall service life of the tool and reducing the replacement frequency of the tool.

[0027] When the gear burr of the gear 6 is removed by the gear hobbing machine burr disc cutter provided by the utility model, first, the first cutting edge 2 cuts the gear burr of the gear 6 once to remove the coarse burr, then the second cutting edge 3 cuts the gear burr of the gear 6 twice to remove the fine burr, the effective removal of the burr is realized through the cooperation of the first cutting edge 2 and the second cutting edge 3, the quality of burr removal is improved, the cutting processing quality and the cutting efficiency are improved, the cutting edge can be effectively protected, the service life of the tool is improved, and the tool is avoided from being frequently replaced; meanwhile, the disc cutter is adopted, the first cutting edge 2 and the second cutting edge 3 are two concentric circles with different radii, the effective cutting area of the cutting edge is increased, when the cutting edge of a certain area of the disc cutter is dull, only one angle of the tool needs to be rotated to generate a new cutting edge to continue effective cutting, thereby improving the overall service life of the tool and reducing the replacement frequency of the tool.
