[0014] In summary, this application includes the following beneficial technical effects:

[0015] 1. Through the rotation of the two first bevel gears, the first bevel gear drives the second bevel gear meshing on the outside to drive the first threaded rod installed on the top to rotate. When the first threaded rod rotates, since the first threaded rod is threadedly connected with the threaded sleeve, the rotation of the first threaded rod drives the top threaded sleeve to extend upward, thereby adjusting the height of the top cutting assembly. The device can be raised and lowered through the threaded sleeve. When it needs to be stored, the threaded sleeve only needs to be rotated to the top of the limit block to complete the storage of the device, thereby solving the problem that the device is too long to be stored.

[0016] 2. The lifting and lowering of the cutting assembly is controlled by the lifting of the threaded sleeve. Workers only need simple operations to complete the height adjustment, which greatly reduces the labor intensity of workers. Only one first motor is needed to control the height of the device. It is highly practical, ensures the height adjustment accuracy of the plasma cutting machine, and improves the accuracy and stability of cutting. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0021] The following is combined with Figure 1-3 This application is described in further detail.

[0022] The present application embodiment discloses a plasma cutting machine for steel structure processing. Figure 2 A plasma cutting machine for steel structure processing includes a mounting base 1, a first motor 2 is arranged on one side of the mounting base 1, an output end of the first motor 2 is connected to a rotating shaft 3 through a first coupling, a side of the rotating shaft 3 away from the first motor 2 is rotatably connected to the inner side of the mounting base 1, two first bevel gears 4 are fixedly connected to the outer side of the rotating shaft 3, and an adjustment mechanism is arranged on the mounting base 1.

[0023] Reference Figure 1-3 The adjustment mechanism includes two limit blocks 8, the inner sides of the two limit blocks 8 are rotatably connected to the first threaded rod 6, and the bottoms of the two first threaded rods 6 are fixedly connected to the second bevel gear 5 through a connecting rod; since the first bevel gear 4 is meshed with the second bevel gear 5, the first bevel gear 4 drives the top second bevel gear 5 to rotate.

[0024] Reference Figure 2-3 The two second bevel gears 5 are meshed with the top of the first bevel gear 4, the outer sides of the two first threaded rods 6 are threadedly connected with threaded sleeves 7, and the tops of the two threaded sleeves 7 are fixedly connected with connecting blocks 9; the first threaded rod 6 is threadedly connected to the threaded sleeve 7, and when the first threaded rod 6 rotates, the first threaded rod 6 can drive the threaded sleeve 7 threadedly connected on the outer side to move up and down.

[0025] Reference Figure 2 One side of the two connecting blocks 9 is fixedly connected to the same mounting block 10, and one side of the mounting block 10 is fixedly connected to a second motor 11; when the second motor 11 rotates, the second motor 11 drives the second threaded rod 13 at the output end to rotate through the second coupling, and the second threaded rod 13 drives the cutting assembly 12 connected to the outer thread to move.

[0026] Reference Figure 3 The output end of the second motor 11 is connected to the second threaded rod 13 through a second coupling, and the side of the second threaded rod 13 away from the second motor 11 is rotatably connected to the inner side of the second motor 11, and the outer side of the second threaded rod 13 is threadedly connected to the cutting assembly 12; when the two first bevel gears 4 rotate, the first bevel gear 4 drives the second bevel gear 5 meshing on the outer side and then drives the first threaded rod 6 installed on the top to rotate. When the first threaded rod 6 rotates, since the first threaded rod 6 is threadedly connected to the threaded sleeve 7, the rotation of the first threaded rod 6 drives the top threaded sleeve 7 to extend upward, thereby adjusting the height of the top cutting assembly 12.

[0027] Reference Figure 1 The cutting assembly 12 includes a plasma cutting nozzle and a mounting frame. The cutting assembly 12 is an existing device and will not be described in detail here.

[0028] The implementation principle of a plasma cutting machine for steel structure processing in the embodiment of the present application is as follows: when it is necessary to process a workpiece, the staff first places the device in a suitable position, and then starts the first motor 2. The first motor 2 drives the rotating shaft 3 at one end thereof to rotate through the first coupling. When the rotating shaft 3 rotates, the rotating shaft 3 drives the two first bevel gears 4 fixedly connected on the outside to rotate. When the two first bevel gears 4 rotate, the first bevel gear 4 drives the second bevel gear 5 meshed on the outside to further drive the first threaded rod 6 installed on the top to rotate. When the first threaded rod 6 rotates, since the first threaded rod 6 is threadedly connected to the threaded sleeve 7, the rotation of the first threaded rod 6 drives the top threaded sleeve 7 to extend upward, thereby adjusting the height of the top cutting assembly 12. The device can be lifted and lowered by the threaded sleeve 7. When it needs to be stored, it only needs to be rotated to the top of the limit block 8 to complete the storage of the device, thereby solving the problem that the device is too long to be stored.

[0029] By controlling the lifting of the cutting assembly 12 through the lifting of the threaded sleeve 7, workers only need simple operations to complete the height adjustment, which greatly reduces the labor intensity of workers. Only one first motor 2 is needed to control the height of the device, which is highly practical, ensures the height adjustment accuracy of the plasma cutting machine, and improves the accuracy and stability of cutting.
