[0021] The present invention will be further described below with reference to the accompanying drawings:
[0022] See attached document Figure 1-7 In this embodiment, a horizontal CNC gear hobbing machine tool includes a housing 1 and a base 12. The lower end of the housing 1 is fixedly connected to the base 12, and the inner wall of the housing 1 is fixedly connected to a partition 4. One end of the partition 4 is threadedly connected to the outer wall of a motor 5 through multiple screws. The output shaft of the motor 5 is rotatably connected to the partition 4 through a bearing. The motor 5 can meet the working requirements according to actual needs. The output shaft of the motor 5 is fixedly connected to a disc 6. The outer wall of the disc 6 is provided with a limiting structure 9, and the upper end of the base 12 is provided with a support structure 2.
[0023] The other end of the top block 202 is fixedly connected to the telescopic end of the hydraulic cylinder 3. The outer wall of the hydraulic cylinder 3 is fixedly connected to the inner wall of the outer shell 1. The hydraulic cylinder 3 can meet the working requirements according to actual needs. The outer wall of the round rod 903 is inserted into the gear material 11. The two ends of the gear material 11 are respectively abutted against the round rod 903 and the top block 202. The right end of the round rod 903 is inserted into the top block 202. The inside of the outer shell 1 is provided with the gear hobbing machine body 10. The rotating part of the gear hobbing machine body 10 is equipped with a hob 7. The outer wall of the outer shell 1 is provided with a protective door 8. The outer wall of the outer shell 1 is provided with a control panel 13. The control panel 13 is electrically connected to the motor 5, the hydraulic cylinder 3 and the gear hobbing machine body 10 respectively.
[0024] The support structure 2 includes a first bolt 203 and a horizontal plate 204. The horizontal plate 204 is threadedly connected to the base 12 by a plurality of first bolts 203. A support plate 201 is fixedly connected to the upper end of the horizontal plate 204. The support plate 201 is slidably connected to the top block 202 through a sliding groove on its surface. One end of the top block 202 is provided with a groove.
[0025] The limiting structure 9 includes a second bolt 901 and a mounting plate 902. The mounting plate 902 is threadedly connected to the disc 6 by multiple second bolts 901. The right end of the mounting plate 902 is fixedly connected to the round rod 903.
[0026] Working principle:
[0027] When using a horizontal CNC gear hobbing machine:
[0028] The operator places the gear material 11 onto the surface of the round rod 903 from the right side, so that one side of the gear material 11 is pressed against the surface of the round rod 903. At the same time, the operator controls the hydraulic cylinder 3 to work, so that the telescopic end of the hydraulic cylinder 3 extends and drives the top block 202 to move synchronously. The top block 202 can cooperate with the round rod 903 to clamp the gear material 11 (the top block 202 is a split structure, and the two parts are rotatably connected by bearings. The part that is pressed against the gear material 11 can rotate, while the other part slides against the slide rod provided on the inner wall of the outer shell 1. Under the restriction of the outer shell 1, the other part of the top block 202 cannot rotate). The operator controls the gear hobbing machine body 10 to work. The gear hobbing machine body 10 controls the hob 7 to press against the surface of the gear material 11, and at the same time controls the motor 5 to work. The motor 5 drives the gear material 11 to rotate synchronously through the disc 6, so that the hob 7 can rotate relative to the gear material 11 after pressing against it. Through the meshing motion between the hob 7 and the gear material 11, an open-tooth shape is formed.
[0029] Replacement process:
[0030] When processing gear raw materials 11 of different diameters, the operator rotates and removes the second bolts 901 on both sides, allowing the mounting plate 902 to be removed. The mounting plate 902 is then replaced with one of a different diameter round rod 903 and reinstalled. When the width of the gear raw material 11 is different, the operator rotates and removes multiple first bolts 203, allowing the horizontal plate 204 to move. The horizontal plate 204 is then fixed to the threaded holes at different positions on the surface of the base 12 by the first bolts 203, allowing the distance between the support plate 201 and the round rod 903 to be adjusted, thus enabling the fixing of multiple gear raw materials 11 of different widths. Although this utility model has been illustrated and described with reference to preferred embodiments, those skilled in the art should understand that various changes in form and detail are possible within the scope of the claims.
