[0002] Plasma powder welding is a process that uses plasma arc discharge to heat metal powder to the melting point and rapidly solidify to form a welded joint. Its advantages include suitability for a variety of metal materials, fast welding, high strength, low heat input, and isotropy. The clamping tool is crucial in this process, as it fixes and stabilizes the position of the welded joint, effectively conducts heat, and controls stress and deformation during welding, ensuring welding quality and stability.

[0003] In the traditional plasma powder welding process, although the machine can drive the workpiece to move during use, when processing round pipes, the existing clamping tool cannot rotate when the round pipes are fixedly welded, and in most cases, the outer wall of a round workpiece of a single size is clamped for welding. However, clamping the outer wall of the round workpiece and being unable to adjust according to the workpiece will affect the implementation of the welding work, so that the practicality of the clamping tool is greatly reduced. Therefore, a clamping tool for plasma powder welding is proposed to solve the above problem. Utility Model Content

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] Reference Figure 1 and Figure 2 The utility model provides an embodiment: a clamping tool for plasma powder welding, comprising a workbench 1, a left-right symmetrical limit slide rail 2 is fixedly connected to the upper surface of the workbench 1, a sliding plate 3 is slidably connected to the outer wall of the limit slide rail 2, a motor 4 is fixedly connected to one side of the outer wall of the sliding plate 3, a turntable 5 is fixedly connected to the output end of the motor 4, a hydraulic rod 6 is fixedly connected to one side of the outer wall of the turntable 5, a fixed rod 7 is fixedly connected to the output end of the hydraulic rod 6, a limit assembly 8 is arranged on one side of the outer wall of the turntable 5, and a plurality of fixed rods 7 are fixedly connected to the outer wall of the fixed rod 7. The hinge seat 19 has a connecting plate 10 rotatably connected to the inner wall of the hinge seat 19, and one side of the outer wall of the connecting plate 10 is rotatably connected to the hinge seat 2 11, and one side of the outer wall of the hinge seat 2 11 is fixedly connected to an arc plate 12, and the outer wall of the arc plate 12 is fixedly connected to an anti-slip pad 13; the limit assembly 8 includes a connecting rod 801, one end of the connecting rod 801 is fixedly connected to one side of the outer wall of the rotating disk 5, and the other end of the connecting rod 801 is fixedly connected to a fixed plate 802, and the outer wall of the fixed plate 802 is fixedly connected to a sleeve 803, and the sleeve 803 is slidably connected to the fixed rod 7;

[0023] Specifically, by putting the pipe fitting outside the anti-skid pad 13, starting the hydraulic rod 6, driving the hinge seat 9 on the outer wall of the fixed rod 7 to slide, and then driving the connecting plate 10 to rotate, so that the anti-skid pad 13 on the outer wall of the arc plate 12 clamps the inner wall of the pipe fitting according to the diameter of the pipe fitting. Then start the motor 4 to drive the turntable 5 to rotate, and realize multi-angle welding.

[0024] Reference Figure 3The upper surface of the workbench 1 is fixedly connected with a symmetrical stabilizing block 14, and a screw rod 15 is rotatably connected inside the stabilizing block 14; a hollow net 16 is fixedly connected inside the workbench 1, and a pulley 17 is fixedly connected to one side of the outer wall of the screw rod 15; a motor 2 18 is fixedly connected to the inner wall of the workbench 1, and a pulley 2 19 is fixedly connected to the output end of the motor 2 18, and a belt 20 is arranged between the pulley 2 19 and the pulley 17;

[0025] Specifically, when the lengths of the pipes are different, the second motor 18 will start, driving the belt 20 on the outer wall of the second pulley 19 to transmit. The belt 20 drives the screw rod 15 to rotate through friction with the inner wall of the first pulley 17. The rotation of the screw rod 15 realizes the linear movement of the sliding plate 3 through the cooperation of the thread and the sliding plate 3.

[0026] Reference Figure 1 - Figure 3 The top plate of the inner wall of the workbench 1 is fixedly connected with a collecting bucket 21, and the lower surface of the collecting bucket 21 is fixedly connected with a collecting box 22; the inside of the collecting box 22 is slidably connected with a collecting box 23, and the collecting box 23 is arranged directly below the collecting bucket 21; a left-right symmetrical cleaning brush 24 is fixedly connected to one side of the outer wall of the sliding plate 3, and the outer wall of the cleaning brush 24 is slidably connected to the upper surface of the hollow net 16;

[0027] Specifically, during the welding process, the powder on the surface of the pipe will be captured by the hollow mesh 16. Due to the special design of the hollow mesh 16, the powder will pass through the mesh smoothly and fall into the collection bucket 21 below. The design of the collection bucket 21 allows the powder to flow smoothly into the inner wall of the collection box 23. As the welding process continues, the powder continues to accumulate in the collection box 23. At this time, we drive the sliding plate 3 to clean the outer wall of the hollow mesh 16 with the cleaning brush 24. The design of the cleaning brush 24 can effectively remove the powder without damaging the hollow mesh 16. This cleaning method is not only simple and efficient, but also ensures that the hollow mesh 16 always maintains a good working condition.

[0028] Working principle: When it is necessary to weld a circular pipe fitting, the pipe fitting is placed outside the anti-skid pad 13, and the hydraulic rod 6 is started to drive the hinge seat 9 on the outer wall of the fixed rod 7 to slide, and the hinge seat 9 is then used to drive the connecting plate 10 to rotate, thereby achieving the effect of driving the anti-skid pad 13 on the outer wall of the arc plate 12 to clamp the inner wall of the pipe fitting according to the different diameters of the pipe fitting, and then the motor 4 is started to drive the turntable 5 to rotate, thereby achieving the effect of facilitating multi-angle welding;

[0029] Secondly, powder will remain on the surface of the pipe during welding, and the powder will fall through the hollow mesh 16 into the collecting bucket 21, and then fall onto the inner wall of the collecting box 23. When the pipes have different lengths, the belt 20 on the outer wall of the pulley 2 19 is driven by starting the motor 2 18, and the screw 15 on the inner wall of the pulley 1 17 is driven by the belt 20 to rotate, and the sliding plate 3 is driven by the screw 15 to transmit the power. At this time, the transmission of the screw 15 can facilitate adjustment according to the length of the pipe, and the cleaning brush 24 is driven by the sliding plate 3 to further clean the powder on the outer wall of the hollow mesh 16.

[0030] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
