The multiple hob discs 72 are mounted with multiple hob blades 73 distributed in a circular array. The multiple hob blades 73 are respectively inserted into the corresponding mounting grooves 721.

[0028] The lifting mechanism 2 includes two linear modules 21 fixedly connected to the frame 1 and vertically arranged. A connecting frame 22 is fixedly installed on the slider of the two linear modules 21. The top of the two connecting frames 22 is fixedly installed with the same rotating ring 23. The top of the rotating ring 23 is rotatably installed with an annular plate 24. The top of the annular plate 24 is provided with multiple slots 241 distributed in a circular array.

[0029] A circular opening 11 is opened on the frame 1, and the supporting assembly 3 includes a rotating ring 2 31 embedded and rotatably mounted on the top of the frame 1. The rotating ring 2 31 is coaxially arranged with the circular opening 11. A plurality of connecting rods 32 distributed in a circular array are fixedly mounted on the top of the rotating ring 2 31. The same annular plate 2 33 is fixedly mounted at one end of the plurality of connecting rods 32 close to each other, and a chuck 34 is fixedly mounted on the bottom of the annular plate 2 33.

[0030] The tops of the multiple connecting rods 32 are fixedly mounted with the same annular plate three 35, and the outer fixed sleeve of the annular plate three 35 is provided with an end face gear disc 36. The supporting assembly 3 also includes a motor 37 fixedly mounted on the top of the frame 1, and a gear 38 is fixedly mounted on the output shaft of the motor 37. The gear 38 is meshed with the end face gear disc 36.

[0031] A plurality of locking mechanisms 39 distributed in a circular array are installed on the top of the annular plate three 35. The locking mechanism 39 includes an L-shaped plate 391 fixedly connected to the annular plate three 35. A reduction motor 394 is fixedly installed on the L-shaped plate 391.

The bottom end of the rotating shaft 392 is higher than the top of the connecting rod 32. A cam 393 is fixedly sleeved on the rotating shaft 392, and multiple cams 393 are located at different positions and heights.

[0032] Furthermore, the multiple cams 393 at different heights can position and fix the cutter discs 72 at different positions, ensuring that when the upper cutter disc 72 is driven up by the multiple cutter blades 73, the position height of the lower cutter disc 72 is not affected in any way.

A swing frame 63 is fixedly installed on the slider of the linear module 3 62, and a welding head 64 is installed on the swing frame 63.

[0034] Furthermore, by controlling the linear module 3 62 to drive the welding head 64 to move horizontally, and cooperating with the swing frame 63 to drive the welding head 64 to swing longitudinally, and then by driving the entire hob body 7 to rotate by the supporting assembly 3 and the lifting mechanism 2, and then by driving the entire welding mechanism 6 to move up and down by the two linear modules 2 4, the connecting edge of the hob blade 73 and the mounting groove 721 can be fully welded and fixedly connected;

[0035] The distance between the welding head 64 and the axis of the hob shaft 71 can be adjusted by the swing frame 63, and the full welding fixation of the connection between the hob shaft 71 and the hob disc 72 can be completed by coordinating the rotation of the hob body 7.

[0036] A magnetic ring is embedded and fixedly installed on one side of the annular plate 2 33 and the annular plate 1 24 where the two rings are close to each other, and the magnetic poles of the two magnetic rings are opposite on the side where the two rings are close to each other.

[0037] The cams 393 are then controlled to deflect against the sides of the corresponding hob discs 72, so that each hob disc 72 can be tightly fixed to the hob shaft 71. At this time, the state of the hob body 7 is as follows: Figure 8 As shown in a;

[0038] Then, the lifting mechanism 2 is controlled to drive the multiple hob blades 73 to rise. At this time, the multiple hob blades 73 will spirally rise in the corresponding mounting grooves 721. When the position between the top of the multiple hob blades 73 and the uppermost hob disc 72 reaches the target distance, the lifting mechanism 2 is stopped to drive the multiple hob blades 73 to rise, and the corresponding cam 393 is controlled to rotate to unlock the uppermost hob disc 72. Then, the multiple hob blades 73 and the uppermost hob disc 72 are spot-welded and fixed by the welding mechanism 6. At this time, the state of the hob body 7 is as follows Figure 8 As shown in b;

[0039] Then, the lifting mechanism 2 is controlled to drive the multiple hob blades 73 to rise. At this time, the multiple hob blades 73 will spirally rise in the corresponding mounting grooves 721 and drive the top hob disc 72 to move upward along the axis of the hob shaft 71. Then, the hob disc 72 located in the middle part is raised along the axis of the hob shaft 71 to the target height and is spot-welded and fixed together with each hob blade 73. At this time, the state of the hob body 7 is as follows: Figure 8 As shown in c;

[0040] Afterwards, when the spacing between the plurality of hob discs 72 reaches the target position on the hob shaft 71, the plurality of hob blades 73 are also fixedly connected with the respective hob discs 72 by spot welding, and the state of the entire hob body 7 is as follows: Figure 8As shown in d, at this time, the annular plate 2 33 is also magnetically connected to the annular plate 1 24 through two magnetic rings, and then the gear 38 is driven to rotate by the starting motor 37, and the gear 38 then drives the annular plate 35 to rotate through the end face gear plate 36, and the annular plate 35 then drives the annular plate 2 33 and the chuck 34 and the annular plate 1 24 to rotate synchronously through multiple connecting rods 32. At this time, the entire hob body 7 will rotate, and then the two linear modules 2 4 and the two L-shaped frames 5 drive the welding mechanism 6 to move up and down to cooperate with the rotation of the hob body 7, so as to complete the full welding and fixed connection between the hob shaft 71 and the hob disc 72, and between the hob disc 72 and the hob blade 73. At this time, the state of the hob body 7 is as shown Figure 8 As shown in d.
