The role of gear hobbing machines is not limited to traditional gear processing; their technological iterations (such as CNC machining) continuously drive the manufacturing industry towards higher precision and efficiency, making them a cornerstone piece of equipment in the manufacture of mechanical transmission components.

[0003] Current gear hobbing machines typically have only one station. Therefore, after the workpiece blank (such as a turbine) to be processed is fixed, the processing operation is carried out. After the processing is completed, the processed workpiece needs to be removed and a new workpiece blank needs to be installed and fixed. As a result, the effective time of gear hobbing operation is short, resulting in poor efficiency of batch operation. Utility Model Content

Figure 1-5 It includes a support platform 2, with a bracket 1 welded to the bottom of the support platform 2. The support platform 2 is equipped with a needle tail propulsion mechanism and a clamping drive mechanism. The clamping drive mechanism is used to drive the tap 9 to rotate. The station conversion mechanism can install two workpieces to be processed. The station conversion mechanism can drive the two workpieces to contact the tap 9 separately.

The first slider is slidably connected to the inner wall of the first sliding groove. A needle tail 6 is fixedly installed at the top end of the first support base 3. A first threaded rod 4 is threadedly connected to the first support base 3. The end of the first threaded rod 4 is rotatably connected to a first upright plate 5, that is, the first upright plate 5 is rotatably connected to the first threaded rod 4 through a bearing. The first upright plate 5 is welded to the support platform 2.

[0026] The clamping drive mechanism includes a second support base 10 fixedly installed on the support platform 2. A motor 11 is fixedly installed on the second support base 10. A chuck 12 is fixedly installed on the output shaft of the motor 11, and the tap 9 is clamped by the chuck 12.

[0027] The workstation conversion mechanism includes a sliding support plate 13 that is slidably connected to the support platform 2. Specifically, the support platform 2 has a second sliding groove at its top, and a second slider is fixedly installed at the bottom of the sliding support plate 13. The second slider is slidably connected to the inner wall of the second sliding groove. A U-shaped support plate 7 is provided on the sliding support plate 13, and two support threaded rods 71 ​​are welded on the U-shaped support plate 7. A guide rail 8 is welded on the sliding support plate 13, and the U-shaped support plate 7 and the guide rail 8 are slidably connected.

[0028] The bottom of the U-shaped support plate 7 is provided with a threaded hole 73, and the inner wall of the threaded hole 73 is threadedly connected to a second threaded rod 14. The support platform 2 is provided with a rectangular through hole 21, through which the second threaded rod 14 passes.

Two workpiece blanks 17 (such as turbine blanks) are then placed on the support threaded rod 71 and secured with fastening bolts 18. Rotating the second threaded rod 14 drives the U-shaped support plate 7 to rise and fall, so that the height of the workpiece blank 17 matches that of the tap 9.
