[0036] See also Figure 1-Figure 3 As shown, this embodiment is a plasma cutting device for welding grooves of strip plates, comprising:

[0037] The main body component includes a plate 11 and a cutter 12;

[0038] The plate 11 is located below the cutter 12;

[0039] The plate 11 is in strip shape, and the cutter 12 is used to cut the plate 11;

[0040] The limiting assembly includes a set of locking buttons 21, a set of connecting rods 22, a placement frame 23, and a bolt rod 24;

[0041] The lock button 21 is movably connected to the edges of both sides of one end of the cutter 12, the connecting rod 22 is clamped to the edges of both sides of the bottom surface of one end of the cutter 12, the placement frame 23 is fixed to the bottom end of the connecting rod 22, and the bolt rod 24 passes through the outer sides of the placement frames 23 on both sides;

[0042] There are two locking buttons 21. Pressing the locking buttons 21 can separate the connecting rod 22 from the cutter 12. The locking buttons 21 are located at the left and right edges of the front end of the cutter 12. The connecting rod 22 is clamped on the left and right sides of the bottom surface of the front end of the cutter 12. The connecting rod 22 is used to connect the placement frame 23. The placement frame 23 is used to place the bolt rod 24. The bolt rod 24 runs through the left and right placement frames 23. The bolt rod 24 is used to place other components.

[0043] The inner side of the lock button 21 is clamped with the top of the connecting rod 22, and the two sides of the bolt rod 24 are sleeved with bearing wheels 25, which are located on the outer side of the placement frame 23;

[0044] Pressing the lock button 21 can separate the connecting rod 22 from the cutter 12, and the bearing wheel 25 can move linearly on the plate 11. When the bearing wheel 25 moves, it can drive the cutter 12 to move linearly;

[0045] The outer end of the bolt rod 24 is sleeved with a limiting ring 26, and the limiting ring 26 is closely attached to the outer side of the bearing wheel 25;

[0046] Both ends of the bolt rod 24 are threadedly connected with screw rings 27;

[0047] The limiting ring 26 is used to limit the bearing wheel 25 to prevent the bearing wheel 25 from being offset when moving. The screw ring 27 is located at the left and right ends of the bolt rod 24 and on the outer side of the limiting ring 26. At the same time, the screw ring 27 limits the limiting ring 26.

[0048] Working principle:

[0049] When the assembly is used, the screw ring 27 is tightened, and then the staff places the cutter 12 on the strip plate 11 to be cut, starts and pushes the cutter 12, and the thrust causes the cutter 12 to move on the plate 11 through the bearing wheel 25. When the cutter 12 moves, the left and right limit rings 26 are tightly attached to the left and right sides of the plate 11, so that the cutter 12 cuts the plate 11 while moving;

[0050] After cutting, the lock button 21 is pressed to separate the connecting rod 22 from the cutter 12, thereby realizing the disassembly of the assembly;

[0051] In the above steps, the cutter 12 cuts along the direction of the plate 11 through the interaction between the bearing wheel 25 and the limiting ring 26 .

[0060] The counterweight block 371 and the support rod 37 are used to support the first guide rod 33 and the second guide rod 36 above, so that the cutter 12 can move along the direction of the guide rod through the guide ring 32. The support rod 37 also has a plug-in slot 38 at a corresponding position below the guide rod.

[0061] The bottom surfaces of the first guide rod 33 and the second guide rod 36 are each provided with a set of insertion grooves 38;

The control rod 16 is twisted to control the left and right up and down cutting distance. The control rod 16 is located at the right end of the screw 13;

[0066] Working principle:

[0067] The staff holds the first guide rod 33, inserts the first guide rod 33 into the guide ring 32, then inserts the mounting rod 35 into the mounting groove 34, and rotates the second guide rod 36 to connect the first guide rod 33 with the second guide rod 36;

[0068] Then, the top end of the support rod 37 is inserted into the insertion groove 38 below the outer ends of the first guide rod 33 and the second guide rod 36, so that the support rod 37 and the counterweight block 371 support the guide rod connected above together. When the cutter 12 moves through the bearing wheel 25, the cutter 12 moves on the surface of the first guide rod 33 and the second guide rod 36 through the guide ring 32, so that the guide rod and the guide ring 32 assist in guiding the moving cutter to prevent the vibration generated when the cutter 12 is in operation from causing the rear side of the cutter 12 to deviate.
