Although this utility model has been described in conjunction with its preferred embodiments, these embodiments are merely illustrative and not intended to limit the scope of this utility model.

[0024] Combined with appendix Figure 1-2 As shown, an improved end-face gear hobbing machine includes a worktable 1. A support base 3 is mounted on one end of the worktable 1. A rotary motor 2 is mounted on one side of the support base. An output shaft 4 is provided on one end of the rotary motor 2. A clamping head 5 is mounted on one end of the output shaft 4.

The tool holder 13 is a rotatable tool holder that can drive the angle adjustment of the tool head 10. A nut sleeve 18 is mounted on the bottom of the support plate 14. The nut sleeve 18 is sleeved on a lead screw 17. A drive motor 19 is mounted on one side of the lead screw 17.

[0025] The clamp head 5 has a clamp groove 21. An electric slide rail 27 is installed at the bottom of the clamp groove 21. Electric sliders 22 are symmetrically installed on the electric slide rail 27. Arc-shaped clamping blocks 8 are installed on each electric slider 22. A sleeve 23 is installed on one side of the arc-shaped clamping block 8. A compression spring 29 is installed on one side of the sleeve 23.

[0026] In addition, it also includes an external industrial control computer, which is electrically connected to the processing equipment to achieve automatic control.

[0027] Specifically, the clamp groove 21 has a receiving groove 20 on its side wall. The receiving groove 20 is cylindrical, and a sleeve rod 28 is installed inside the receiving groove 20.

[0028] Specifically, the compression spring 29 is fitted onto the sleeve rod 28 and is in a contracted state. One end of the sleeve 23 is fitted with a pressure plate 25. One end of the compression spring 29 is connected to the pressure plate 25, and the other end of the compression spring 29 is connected to the bottom of the receiving groove 3. The rebound force of the compression spring 29 is used to push the pressure plate 25 to cause the opposite arc-shaped clamping blocks 8 to move towards each other, ensuring further stable clamping of the workpiece blank.

[0029] Specifically, a sleeve groove 24 is provided inside the sleeve 23, and one end of the sleeve rod 28 extends into the sleeve groove 24.

[0030] Specifically, a support rod is installed on the electric slider 22, and the arc-shaped clamping block 8 is connected to the electric slider 22 through the support rod. In addition, the electric slide rail 27 and the electric slider 22 are electrically connected to an external industrial control computer. Under the control of the external industrial control computer, the arc-shaped clamping block 8 can move automatically towards or away from each other to ensure stable clamping.

[0031] Specifically, a magnetic layer 26 is provided on one side surface of the arc-shaped clamping block 8. The magnetic effect of the magnetic layer 26 makes the clamping more secure and ensures the normal operation of the gear hobbing process.

[0032] Specifically, slides 15 are installed on both sides of the bottom of the support plate 14. The support plate 14 is slidably mounted on the linear guide rail 9 via the slides 15. The slides 15 and the linear guide rail 9 provide further power for the support plate 14 to move forward and backward.

[0033] Specifically, a stop block 16 is installed at one end of the lead screw 17 near the clamp head 5. The stop block 16 is used to prevent the nut sleeve 18 from moving out of range and to prevent the tool holder 13 from hitting the clamp head 5. A support block 6 is installed at one end of each linear guide rail 9. A stop rod 7 is installed on one side of the support block 6. The stop rod 7 is threadedly connected to the support block 6 by a nut, and the distance of the stop rod 7 beyond the support block 6 is adjustable. The stop rod 7 is used to prevent the support plate 14 from moving out of range.

[0034] Specifically, the tool holder 13 is equipped with a plurality of nozzles 11 on its side. The nozzles 11 are made of metal corrugated hoses, that is, the nozzles 11 are telescopic and flexible, so as to achieve better alignment with the direction of cutting fluid feeding.

[0035] Specifically, the tool holder 13 is provided with a cutting fluid inlet 12 at the top, which is connected to an external fluid supply tank. The tool holder 13 is provided with a fluid inlet channel, which is connected to the nozzle 11. By supplementing the external cutting fluid, the cutting fluid can cool or lubricate the workpiece.

[0036] The specific working principle of this utility model is as follows:

[0037] The workpiece blank to be hobbing is placed in the arc-shaped clamping block 8. Under the control of an external industrial control computer, the electric slide rail 27 is driven, causing the electric slider 22 to move the arc-shaped clamping block 8 towards each other, thus clamping the workpiece blank. The elasticity of the compression spring 29 further ensures the stability of the clamping by pushing the pressure plate 25. Then, under the control of the external industrial control computer, the drive motor 19 is started, moving the nut sleeve 18 along the lead screw 17 in the machining direction, causing the cutter head 10 of the tool holder 13 to move to the machining surface of the workpiece blank. Simultaneously, the rotary motor 2, driven by the external industrial control computer, rotates the fixture head 5, realizing the hobbing of the workpiece blank. After machining, the nut sleeve 18 moves away from the machining direction on the lead screw 17, causing the cutter head 10 of the tool holder 13 to move away from the workpiece blank. During machining, the nozzle 11 cools or lubricates the workpiece with cutting fluid.

[0038] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any modifications and substitutions based on the technical solutions and inventive concepts provided by the present utility model should be covered within the protection scope of the present utility model.
