[0024] This section will describe in detail the specific embodiments of the present invention. The preferred embodiments of the present invention are shown in the accompanying drawings. The purpose of the accompanying drawings is to supplement the description of the text part of the specification with graphics, so that people can intuitively and vividly understand each technical feature and overall technical solution of the present invention, but it cannot be understood as a limitation on the scope of protection of the present invention.

[0025] Reference Figure 1-5 A gear hobbing fixture for gear processing includes a base 1: a fixed block 2 and an L-shaped block 3 are fixedly connected to the upper side of the base 1, a bracket block 4 is fixedly connected to the outer side of the L-shaped block 3, a control structure 5 is provided between the bracket block 4 and the fixed block 2, a workpiece 6 is provided on the upper side of the bracket block 4, a pressure cover block 7 is provided on the upper side of the workpiece 6, two L-shaped blocks 3 are provided, a groove 3 8 is provided on the lower side of the pressure cover block 7, the groove 3 8 is set larger than the deformation block 505, and the lower end of the pressure cover block 7 is set to an inverted frustum. First, install the base 1 on the workbench, and then proceed After installing the L-shaped block 3, the bracket block 4, and the fixing block 2, the control structure 5 is started to adjust the size of the inner ring of the workpiece 6, and then it is fixed. Finally, the workpiece 6 is placed on the upper side of the bracket block 4, and then covered with the pressure cover block 7. The frustum-shaped setting of the lower end of the pressure cover block 7 can not only fix the workpiece 6, but also reduce the distance between the support surface of the workpiece 6 and the point of application of the cutting force, which is convenient for processing. At the same time, the opening size of the groove three 8 is set to be larger than the deformation block 505, which is conducive to controlling the size of the deformation block 505, thereby replacing workpieces 6 with different inner rings.

[0026] The control structure 5 includes a groove 501, which is provided on the upper side of the fixed block 2. A spring 502 is provided in the groove 501. The lower end of the spring 502 is fixedly connected to the fixed block 2. The upper end of the spring 502 is provided with a central axis 504. The upper side of the fixed block 2 is provided with a circular groove 503. A rotating block 507 is provided inside the circular groove 503. The rotating block 507 is threadedly connected to the fixed block 2. A groove 2 509 is provided on the lower side of the rotating block 507. The outer side of the central axis 504 is slidably connected with a deformation block 505. The outer side of the deformation block 505 is provided with an elongated hole 506. The appearance of the central axis 504 is arranged to become thicker from top to bottom. The central axis 504 is fixedly connected to the rotating block 507.
