DETAILED DESCRIPTION

[0031] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0033] Before welding the stainless steel pipe 5, it is necessary to cut a groove at the welding port. At this time, the stainless steel pipe 5 is picked up and placed into the support ring 4 of the guide assembly, and the stainless steel pipe 5 is guided by the support ring 4. At the same time, the stainless steel pipe 5 is pushed in the direction of the support plate 2. At this time, the guide assembly can support the stainless steel pipe 5. When one end of the stainless steel pipe 5 is pushed into the interior of the support frame 3, the adjustment assembly automatically adjusts the position of the cutter 31. Then, the electric telescopic rod 223 is started to push the push block 224 to support the inner wall of the stainless steel pipe 5. Subsequently, the first motor 21 is started to drive the rotating gear 221 to rotate, and the rotating gear 221 drives the first rotating column 22 to rotate. The first rotating column 22 drives the rotating block 222 to rotate, and the rotating block 222 rotates to drive the stainless steel pipe 5 to rotate. At this time, the cutter 31 can cut the groove on the port of the stainless steel pipe 5. After the cutting is completed, the electric telescopic rod 223 drives the push block 224 to separate from the stainless steel pipe 5, and then the stainless steel pipe 5 can be pulled out from the inside of the support frame 3.

[0034] like Figure 3 to Figure 4As shown, the guide assembly also includes a gear ring 41 arranged on the outside of the support ring 4, and six groups of guide rollers 43 with equal spacing are arranged inside the support ring 4. The outer side of the guide roller 43 is rotatably connected to a guide frame 431, and a second rotating column 432 is fixed to the top of the guide frame 431. The top of the second rotating column 432 is rotatably connected to a lifting column 434. A limiting frame 437 is arranged on the side of the lifting column 434 away from the gear ring 41. The bottom end of the limiting frame 437 is fixedly connected to the support ring 4, and the top end of the limiting frame 437 is rotatably connected to a threaded column 435. The outer side of the threaded column 435 is threadedly connected to the inner side of the lifting column 434. A transmission gear 436 is fixed to the top of 435, and the transmission gear 436 is meshedly connected with the gear ring 41. A fourth motor 42 is arranged below the support ring 4, and the fourth motor 42 is fixedly connected to the processing table 1. The end of the rotating shaft of the fourth motor 42 is fixedly connected to the middle of the lowest threaded column 435. A groove for the rotation of the gear ring 41 is provided inside the processing table 1. A support column 44 is arranged on the side of the gear ring 41 away from the transmission gear 436. The bottom end of the support column 44 is fixedly connected to the support ring 4. A limiting block 441 is fixed to the top of the support column 44, and a roller is arranged inside the limiting block 441 for limiting and guiding the gear ring 41.

[0035] When the support ring 4 is limiting and guiding the stainless steel tube 5, the end of the stainless steel tube 5 that needs to be cut is placed into the support ring 4. At this time, the fourth motor 42 is started to drive the transmission gear 436 at the bottom to rotate, and the transmission gear 436 drives the ring gear 41 to rotate. At this time, the ring gear 41 can drive the five transmission gears 436 at other positions to rotate synchronously, and the transmission gear 436 drives the threaded column 435 to rotate. The rotation of the threaded column 435 drives the lifting column 434 to extend into the support ring 4. At this time, the lifting column 434 can drive the guide roller 43 to get close to the stainless steel tube 5. When the six guide rollers 43 contact the stainless steel tube 5, the stainless steel tube 5 can be supported.

[0036] like Figure 4 As shown, a return spring 433 is sleeved on the outside of the second rotating column 432, the top end of the return spring 433 is fixedly connected to the lifting column 434, the bottom end of the return spring 433 is fixedly connected to the guide frame 431, and the angle between the guide roller 43 and the stainless steel pipe 5 is 45°;

[0037] When it is necessary to push the stainless steel tube 5 into the interior of the support frame 3, the stainless steel tube 5 drives the guide roller 43 to roll. At this time, the stainless steel tube 5 drives the guide roller 43 to flip 45°, so that the rotation direction of the guide roller 43 is opposite to the rotation direction of the stainless steel tube 5. At this time, the guide roller 43 can support the stainless steel tube 5. When the stainless steel tube 5 is pushed into the interior of the support frame 3, it will be supported by the push block 224. At this time, the fourth motor 42 is started to rotate in the opposite direction for one circle, so that the guide roller 43 can be separated from the stainless steel tube 5. At this time, the reset spring 433 drives the guide roller 43 to reset. Then the fourth motor 42 rotates forward to drive the guide roller 43 to be close to the stainless steel tube 5. Then the rotating block 222 drives the stainless steel tube 5 to rotate. The guide roller 43 flips 45° with the rotation of the stainless steel tube 5. At this time, the guide roller 43 and the stainless steel tube 5 have the same rotation direction to support the stainless steel tube 5 when it rotates, which can reduce the friction force pushing the stainless steel tube 5.

[0038] like Figure 5 As shown, the adjustment assembly also includes a limit shell 35 disposed between the support plate 2 and the support frame 3, the bottom end of the limit shell 35 is fixedly connected to the processing table 1, and the inner part of the limit shell 35 is rotatably connected to a limit roller 351;

[0039] When the stainless steel tube 5 is pushed toward the inside of the support frame 3 , the limiting roller 351 limits the stainless steel tube 5 . When the stainless steel tube 5 rotates, the limiting roller 351 can rotate along with the stainless steel tube 5 , so that one end of the stainless steel tube 5 can match the position of the cutter 31 .

[0040] like Figure 8 As shown, a flip rod 311 is fixed to the top of the cutter 31, an adjustment frame 34 is arranged at one end of the flip rod 311, a rotating shaft is fixed to one end of the flip rod 311, the flip rod 311 is rotatably connected to the adjustment frame 34 through the rotating shaft, a worm gear 312 is fixed to the other end of the rotating shaft of the flip rod 311, a third motor 345 is installed at one end of the adjustment frame 34 away from the cutter 31, a worm 346 is fixed to the end of the rotating shaft of the third motor 345, both sides of the worm 346 are rotatably connected to the adjustment frame 34 through support blocks, and the worm 346 is meshingly connected to the worm gear 312;

[0041] Before the cutter 31 cuts the stainless steel pipe 5, the angle of the cutter 31 is adjusted as needed. At this time, the third motor 345 is started to drive the worm 346 to rotate, the worm 346 drives the worm wheel 312 to rotate, the worm wheel 312 drives the flip rod 311 to flip, and the flip rod 311 drives the cutter 31 to adjust the angle.

[0042] like Figure 8 As shown, a guide slide post 313 is fixed to one end of the flip rod 311 away from the cutter 31, and a guide groove 341 is formed on one side of the adjustment frame 34 away from the cutter 31, and the guide slide post 313 forms a sliding structure inside the guide groove 341;

[0043] During the turning process of the turning rod 311 , the guide slide column 313 slides inside the guide groove 341 , so as to limit the turning rod 311 and support the turning rod 311 at the same time.

[0044] like Figure 6 As shown, a support frame 32 is fixed to the top of the support frame 3, a second motor 321 is installed on the side of the support frame 32 close to the support frame 3, a threaded rod 322 is rotatably connected inside the support frame 32, a moving frame 323 is arranged inside the support frame 32, the moving frame 323 is threadedly connected to the threaded rod 322, the end of the rotating shaft of the second motor 321 is fixedly connected to one end of the threaded rod 322, a slider 342 is fixed to the side of the adjustment frame 34 close to the support frame 32, a slide groove matching the outer diameter of the slider 342 is opened inside the moving frame 323, a guide rod is fixed inside the slide groove, and the guide rod runs through the inside of the slider 342;

[0045] When the cutter 31 cuts the stainless steel pipe 5, the cutter 31 will cut the stainless steel pipe 5 from shallow to deep. During the cutting process, the second motor 321 is started to drive the threaded rod 322 to rotate, and the threaded rod 322 drives the moving frame 323 to move inside the supporting frame 32. At this time, the moving frame 323 drives the cutter 31 to move through the adjusting frame 34, so as to achieve the cutting groove of the stainless steel pipe 5.

[0046] like Figure 6 As shown, a lifting rod 33 is arranged above the support frame 32, a guide column 331 is fixed to the top of the support plate 2, a collar is fixed to the side of the lifting rod 33 close to the guide column 331, and the collar is slidably connected to the outside of the guide column 331, a connecting frame 343 is fixed to the top of the adjustment frame 34, a lifting sleeve 344 is fixed to the top of the connecting frame 343, and the lifting sleeve 344 is sleeved on the outside of the lifting rod 33;

[0047] When the lifting rod 33 is raised, the connecting frame 343 can be driven by the lifting sleeve 344, and the connecting frame 343 pulls up the adjusting frame 34. At this time, the adjusting frame 34 can drive the cutter 31 to automatically adjust the position according to the outer diameter of the stainless steel pipe 5.

[0049] Before the stainless steel tube 5 enters the interior of the support frame 3, it will first contact the guide slide bar 333. The stainless steel tube 5 pushes the lifting rod 332 up through the curvature of the guide slide bar 333. The lifting rod 332 can drive the lifting rod 33 to rise and adjust the height of the cutter 31. During the rotation of the stainless steel tube 5, the ball 334 rolls at the bottom end of the lifting rod 332 to support the lifting rod 332. The lifting rod 332 is pushed up by the guide slide bar 333 to automatically adjust the height of the cutter 31, thereby reducing manual operation.
