[0002] Laser cladding is a special material surface processing technology, which is usually used to improve the surface properties of materials. Laser cladding layer structure characteristics The structure of the laser cladding layer is formed by the melting action of the beam.

[0015] 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.

[0016] See also Figure 1-2The utility model provides a technical solution: a mixing device for laser cladding powder configuration, comprising a barrel body 1 with legs arranged on the circumferential side, the bottom of the barrel body 1 is open, and the lower end of the barrel body 1 is provided with a bottom plate 8 with adjustable height, the circumferential side of the barrel body 1 is provided with two symmetrically arranged cylinders 7, the bottom of the cylinder 7 is provided with a connecting plate 71 connected to the bottom of the bottom plate 8, and the middle part of the barrel body 1 is provided with a stirrer, the stirrer comprises a rotating shaft 3 rotatably arranged at the upper end of the barrel body 1, the circumferential side of the rotating shaft 3 located at the middle and lower part of the barrel body 1 is provided with a slot 31, and the circumferential side of the rotating shaft 3 corresponding to the slot 31 is slidably provided with a sliding sleeve 4, the lower end of the slot 31 is provided with a movable sleeve with a sleeve 5, and the bottom of the sleeve 5 is connected to the bottom plate 8 is rotatably connected, stirring rods 6 are arranged on the side of the rotating shaft 3, the side of the sliding sleeve 4 and the side of the ferrule 5, and an elastic column 61 is connected between the two adjacent stirring rods 6 above and below. The elastic column 61 can adopt a telescopic rod with a spring inside to control the cyclic shortening and elongation of the cylinder 7. When the cylinder 7 shortens, it drives the bottom plate 8 to move upward through the connecting plate 71, and when the bottom plate 8 moves upward, it drives the ferrule 5 to move upward, and the ferrule 5 drives the stirring rods 6 on its side to move upward. At this time, the stirring rod 6 on the lower side drives the stirring rod 6 in the middle to move upward through the elastic column 61, and the stirring rod 6 in the middle squeezes the elastic column 61 on the upper side. The elastic column 61 changes, and the spacing between the upper, middle and lower stirring rods 6 becomes smaller, thereby changing the stirring effect of the stirring rod 6 on the cladding powder.

[0017] When the cylinder 7 is extended, the cylinder 7 drives the bottom plate 8 to move downward through the connecting plate 71. As can be seen from the above steps, the distance between the upper, middle and lower stirring rods 6 becomes larger, which changes the stirring effect of the stirring rods 6 on the cladding powder.

[0018] Furthermore, a motor 2 is provided on the top of the barrel body 1, and the output shaft of the motor 2 is connected to the top of the rotating shaft 3 through a coupling. The operation of the motor 2 is controlled by an external switch group. The motor 2 drives the rotating shaft 3 to rotate, and the rotating shaft 3 drives the sliding sleeve 4 and the ferrule 5 to rotate. At the same time, the rotating shaft 3, the sliding sleeve 4 and the ferrule 5 all drive their corresponding stirring rods 6 to rotate, and the stirring rods 6 stir and mix the cladding powder.

[0019] Furthermore, the connecting plate 71 is an L-shaped structure.

[0020] Furthermore, a feed pipe is provided on the top of the barrel body 1, and a sealing plug is movably connected to the feed pipe. After adding the configuration powder through the feed pipe, the sealing plug is covered to prevent the raw materials from splashing out through the feed pipe during stirring.

[0021] The motor 2 used in the present invention is a common electronic component in the prior art, and its working mode and circuit structure are well-known technologies, which will not be described in detail here.

[0022] When using:

[0023] After adding the configuration powder through the feed tube, cover with the sealing plug;

[0024] The motor 2 is controlled to work by an external switch group, the motor 2 drives the rotating shaft 3 to rotate, the rotating shaft 3 drives the sliding sleeve 4 and the ferrule 5 to rotate, and at the same time, the rotating shaft 3, the sliding sleeve 4 and the ferrule 5 all drive their corresponding stirring rods 6 to rotate, and the stirring rods 6 stir and mix the cladding powder;

[0025] The cylinder 7 is controlled to shorten and lengthen cyclically. When the cylinder 7 shortens, the bottom plate 8 is driven upward through the connecting plate 71. When the bottom plate 8 is moved upward, the ferrule 5 is driven upward. The ferrule 5 drives the stirring rod 6 on its side to move upward. At this time, the stirring rod 6 on the lower side drives the stirring rod 6 in the middle to move upward through the elastic column 61. The stirring rod 6 in the middle squeezes the elastic column 61 on the upper side. The elastic column 61 changes, and the distance between the upper, middle and lower stirring rods 6 becomes smaller, thereby changing the stirring effect of the stirring rod 6 on the cladding powder.

[0026] When the cylinder 7 is extended, the cylinder 7 drives the bottom plate 8 to move downward through the connecting plate 71. As can be seen from the above steps, the distance between the upper, middle and lower stirring rods 6 becomes larger, which changes the stirring effect of the stirring rods 6 on the cladding powder.

[0027] After the stirring is completed, the cylinder 7 is controlled to be extended to the maximum state, and the cylinder 7 drives the bottom plate 8 to move down to a position separated from the barrel body 1 through the connecting plate 71, and the powder is discharged through the bottom of the barrel body 1.

[0028] The utility model adopts a new stirring mechanism, so that the powder raw materials can be mixed up and down when being stirred, which is convenient for mixing raw materials at different heights and avoiding stratification of the mixed raw materials. The powder raw materials can be fully mixed, thereby ensuring the consistency of performance of various parts of the cladding layer and avoiding interface failure. The laser cladding effect can be improved and the use is convenient.
