[0019] In order to enable those skilled in the art to better understand the solution of the present invention, the technical solution in the embodiment of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiment of the present invention.
[0020] As shown in Figures 1-4, a spraying device for the inner ring of an automobile swing arm includes a spraying body 10, on which a spraying assembly is provided, the spraying assembly includes a sleeve 11 sliding on the outer peripheral side of the spraying body 10, and a spraying block 12 rotating at the bottom of the spraying body 10, a coating chamber 20 is provided inside the spraying block 12, at least two nozzles 21 are provided at the bottom of the spraying block 12, the nozzles 21 are connected to the coating chamber 20, the bottom side end face of the sleeve 11 is an inclined surface, and rubber coating is sprayed on the inclined surface, two symmetrical limit blocks 22 are provided inside the sleeve 11, a plurality of annular grooves are provided on the outer peripheral side of the spraying block 12, the limit blocks 22 slide in the annular grooves, and two adjacent annular grooves form a limit ring 23, and two symmetrically arranged notches 24 are provided on each limit ring 23, and the notches 24 are arranged in a spiral.
[0021] A snap groove 17 is provided at the top of the spray body 10, and a rotating chamber 19 is provided at the bottom of the spray body 10. The spray block 12 rotates in the rotating chamber 19. A power chamber 18 is also provided in the spray body 10. A hollow rotating shaft 13 is fixed to one end face of the spray block 12. The rotating shaft 13 passes through the power chamber 18 and is connected to the snap groove 17. A driven gear 14 is also fixed on the outer peripheral side of the rotating shaft 13. A motor 15 is installed inside the power chamber 18. A driving gear 16 is provided on the motor 15, and the driving gear 16 is meshed with the driven gear 14.
[0022] When in use, the buckle groove 17 of the spray body 10 can be buckled on the spray gun muzzle or the paint pipe, the spray gun muzzle needs to abut against the inside of the rotating shaft 13, and then the inclined surface of the outer sleeve 11 abuts against the edge of the hole to be sprayed, and then the spray gun or paint machine is started to allow the paint to enter the paint chamber 20 through the rotating shaft 13, and then the motor 15 is started at the same time to rotate the driving gear 16, and then drive the driven gear 14 to rotate. The rotation of the driven gear 14 can drive the spray block 12 to rotate through the rotating shaft 13. When the spray block 12 rotates, the paint in the paint chamber 20 will also be sprayed out through the nozzle 21, so that The paint is evenly applied inside the hole. When the spray block 12 rotates nearly one circle, the spraying of this layer is completed. When the spray block 12 drives the notch 24 on the limit ring 23 to move to coincide with the limit block 22, when the spray body 10 is manually pressed, the limit block 22 can fall into the next annular groove, so that the spray block 12 extends a little into the hole to spray the next layer, so that the hole is sprayed evenly and orderly layer by layer. When the spraying is completed, the limit block 22 can be retracted into the outer jacket 11, and the outer jacket 11 can be adjusted to the initial position to complete the reset.
[0023] Obviously, the described embodiments are only a part of the embodiments of the utility model, not all of them.
