[0039] In the embodiment of the present disclosure, as shown in Figures 1 to 7As shown, the upper position of the positioning frame 4 is bolted with a spraying main body 5, and the upper and lower positions of the spraying main body 5 are respectively bolted with a sealing plate 6. The spraying main body 5 comprises a limiting block 501 and a nozzle 502. One side of the spraying main body 5 is provided with a transverse limiting block 501. The outer side of the limiting block 501 is provided with a group of arc-shaped locking protrusions. The upper position of the positioning frame 4 is provided with a locking hole corresponding to the limiting block 501. The limiting block 501 passes through the inside of the locking hole in cooperation with the locking protrusions. The locking hole cooperates with the limiting block 501 and the locking protrusions to achieve the effect of locking the spraying main body 5 at different angles. One side of the limiting block 501 is provided with a threaded rod with a nut. The staff rotates the nut by means of a wrench to lock and unlock the spraying main body 5 respectively. When the spraying main body 5 is unlocked, it can be displaced to one side. At this time, the spraying main body 5 can be flexibly adjusted in angle.

After the staff installs a drainage hose between the fan 2 and the drainage bend, the sealing plate 6 can guide the airflow after being installed. The staff controls the fan 2 to make the airflow flow effectively at the positions of the heat dissipation fins and the stable sleeve, thereby accelerating the heat dissipation speed of the end of the spraying main body 5, prolonging the service life of the spraying main body 5, and avoiding the phenomenon that the end of the spraying main body 5 is damaged after being heated for a long time. In addition, part of the metal dust generated in the electric arc spraying process can be absorbed by the fan 2 at the same time. A dust filter in the prior art can be installed on the basis of the drainage hose, thereby effectively reducing the harm caused by the staff inhaling metal dust.

[0041] In the embodiments of the present disclosure, reference is made to Figures 1 to 7As shown, the worker will select a model of the controller according to the needs of the prior art, the worker will select a model and structure of the spraying body 5 according to the needs of the prior art, and the worker will electrically connect the controller and the spraying body 5 according to the prior art, and the worker will still control the controller according to the prior art to make the spraying body 5 spray the workpiece.

[0042] Example three, on the basis of example one, reference Figures 1 to 7 As shown, it is suggested to adopt a double-drive wheel structure inside the spraying body 5, and through accurate motor control, ensure that the two spraying wires are delivered to the spraying body 5 at a constant speed and uniform tension, the wire feeding pipe is made of high-temperature-resistant, wear-resistant and smooth inner wall material, which effectively reduces the friction resistance of the wire in the conveying process and prevents the occurrence of wire surface damage and wire jamming.

[0044] The working principle of the embodiment is:

[0045] When installing the electric arc spraying device, the worker installs the fan 2 on the upper side of the stable plate of the stable frame 1 through the bolt, ensures that the bottom of the fan 2 is stably connected with the stable plate, and electrically connects the fan 2 with the controller, so as to control the operation of the fan 2 in the later stage, installs the T-shaped sliding block 301 at the bottom of the stable rod 3 into the T-shaped sliding groove in the middle position of the stable frame 1, so that the stable rod 3 can stably move up and down in the sliding groove, and realizes the initial positioning of the stable rod 3 through the adsorption of the magnet at the bottom of the stable rod 3 and the iron block in the upper stable groove;

[0046] Install the positioning frame 4 on the stable rod 3 through the sliding hole on one side, so that the positioning frame 4 can slide up and down along the stable rod 3, the worker installs the spraying body 5 on the upper position of the positioning frame 4 through the bolt, and ensures that the limiting block 501 of the spraying body 5 corresponds to the locking hole in the upper position of the positioning frame 4, then installs the sealing plate 6 on the upper and lower positions of the spraying body 5, so that the stable block at the corner of the sealing plate 6 is installed in the stable groove of the spraying body 5, to ensure the stability of the sealing plate 6, and finally installs the protective cover 7 on the outer side of the nozzle 502 through the bolt, selects a suitable translucent material as the protective cover 7 for welding light shielding, and plays a light shielding role;

[0047] Install the drainage hose between the sealing plate 6 and the drainage bend of the stable sleeve, and connect the drainage hose with the fan 2, to ensure the connectivity of the whole heat dissipation system;

[0048] The spraying angle is adjusted. The worker adjusts the angle of the spraying main body 5 according to the shape of the workpiece and the position to be sprayed. If the angle needs to be adjusted, the worker loosens the nut with a wrench. When the spraying main body 5 is unlocked, it can be displaced to one side. At this time, the spraying main body 5 can be flexibly adjusted in angle. The spraying main body 5 is reversely displaced, so that the locking protrusion of the limiting block 501 passes through the inside of the locking hole again. After the angle of the spraying main body 5 is adjusted, the effect of quick locking is achieved.

[0049] The spraying main body 5 is pushed to one side and then the angle of the spraying main body 5 is adjusted according to the requirement. After the adjustment is completed, the spraying main body 5 is reversely displaced, so that the locking protrusion of the limiting block 501 passes through the locking hole again. The nut is tightened to lock the angle of the spraying main body 5.

[0050] When the electric arc spraying device is used, the worker starts the controller and sets the related parameters according to the spraying process requirements. For example, the spraying current and voltage can be set on the controller. The specific setting interface and method are not listed in detail here, but can be supplemented and improved according to the actual situation.

[0051] The worker starts the fan 2, and the fan 2 starts to work. The airflow enters the heat dissipation system through the drainage hose, and prepares for the heat dissipation of the spraying main body 5.

[0052] The worker holds the positioning frame 4 to control the spraying main body 5 to move to a position suitable for spraying the workpiece, and starts the spraying main body 5. The electric arc is generated inside to melt the spraying material and spray it out through the nozzle 502. The diffusion groove in the nozzle 502 disperses the electric arc outward to expand the spraying range and spray the workpiece. The protective cover 7 blocks the light of the electric arc to protect the eyes of the worker.

[0053] After the workpiece spraying is completed, the worker first closes the spraying main body 5 to stop the spraying operation, and continues to run the fan 2 for a period of time to ensure that the spraying main body 5 is fully cooled and its temperature is reduced to a safe range.

[0054] The fan 2 is turned off, and then the device can be cleaned and maintained as needed to prepare for the next spraying operation.
