DETAILED DESCRIPTION OF THE EMBODIMENTS

[0016] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0017] Please refer toFigures 1-4 , an embodiment provided by the present utility model: an automatic painting device for producing power transformers, including a painting adjustment device 1, the painting adjustment device 1 includes a support base 2, a limit slide bar 3, a lifting plate 4, a threaded rod 5, a top plate 6, a servo motor 7, a mounting fixed plate 8, a bottom turning wedge 9 and a top turning wedge 11. Two limit slide bars 3 are symmetrically arranged, and the bottom ends of the limit slide bars 3 are fixedly connected to the top end of the support base 2. The lifting plate 4 is slidably connected to the two limit slide bars 3. The bottom end of the threaded rod 5 is rotatably connected to the middle of the support base 2 through a rotating shaft. The top plate 6 is fixedly installed at the top ends of the two limit slide bars 3, and the top end of the threaded rod 5 is rotatably connected to the middle of the top plate 6 through a rotating shaft. The servo motor 7 is fixedly installed in the middle of the top end of the top plate 6, and the driving end of the servo motor 7 is fixedly installed at the top end of the threaded rod 5. The mounting fixed plate 8 is rotatably connected to one side of the lifting plate 4 through a damping rotating shaft. The bottom turning wedge 9 is fixedly installed on one side of the support base 2 close to the mounting fixed plate 8. The top turning wedge 11 is fixedly installed on one side of the top plate 6 close to the mounting fixed plate 8.

[0018] One side of the top end of the bottom turning wedge 9 is designed with an oblique cut, and a first point contact switch 10 is fixedly installed on the obliquely cut side of the bottom turning wedge 9. The first point contact switch 10 is electrically connected to the servo motor 7 by wire. The thickness of the bottom turning wedge 9 determines the rotation angle of the mounting fixed plate 8. The thickness of the bottom turning wedge 9 is set according to different situations to make the painting angle optimal.

[0019] One side of the bottom end of the top turning wedge 11 is designed with an oblique cut, and a second point contact switch 12 is fixedly installed on the obliquely cut side of the top turning wedge 11. The second point contact switch 12 is electrically connected to the servo motor 7 by wire. The thickness of the top turning wedge 11 determines the rotation angle of the mounting fixed plate 8. The thickness of the top turning wedge 11 is set according to different situations to make the painting angle optimal, and the thickness of the top turning wedge 11 is the same as the thickness of the bottom turning wedge 9 to ensure that the left and right deflection angles of the mounting fixed plate 8 are the same.

[0020] The oblique cutting surfaces of the bottom turning wedge 9 and the top turning wedge 11 are arranged in reverse symmetry, and the reverse symmetry design makes the up and down movement and deflection of the mounting fixed plate 8 smoother.

[0021] A spray gun 14 is fixedly installed at the top end of the mounting fixed plate 8. The top of one end of the mounting fixed plate 8 close to the lifting plate 4 is fixedly connected with an upper turning rod 13. The bottom of one end of the mounting fixed plate 8 close to the lifting plate 4 is fixedly connected with a lower turning rod 15, and the upper turning rod 13 and the lower turning rod 15 are on the same straight line. According to the reverse symmetry design of the bottom turning wedge 9 and the top turning wedge 11, when the mounting fixed plate 8 moves downward, the lower turning rod 15 can contact the oblique cutting edge of the bottom turning wedge 9, and when the mounting fixed plate 8 moves upward, the upper turning rod 13 can contact the oblique cutting edge of the top turning wedge 11.

[0022] Working principle: During use, first select the appropriate thicknesses of the bottom turning wedge 9 and the top turning wedge 11 according to the size of the groove on the outer shell of the transformer and the size of the nozzle offset angle of the spray gun 14. Convey the transformer outer shell into the painting workshop by means of external forces such as suspension ropes or tracks. The transformer outer shell moves forward slowly under the action of the external force. At the same time, start the servo motor 7. The driving end of the servo motor 7 drives the threaded rod 5 to rotate. The rotation of the threaded rod 5 pushes the lifting plate 4 to move. When the lifting plate 4 moves downward, the lifting plate 4 drives the mounting fixing plate 8 to move downward. The movement of the mounting fixing plate 8 drives the lower turning rod 15 to move downward. When the bottom end of the lower turning rod 15 touches the top end of the bottom turning wedge 9, the lower turning rod 15 slides towards the beveled side of the bottom turning wedge 9. The lower turning rod 15 moves downward and presses the beveled surface of the bottom turning wedge 9. Under the interaction of forces, the lower turning rod 15 is pushed by the beveled surface of the bottom turning wedge 9 and moves towards the side close to the first point contact switch 10. The movement of the lower turning rod 15 in the horizontal direction drives the mounting fixing plate 8 to rotate. The rotation of the mounting fixing plate 8 drives the spray gun 14 to rotate, and the rotation of the spray gun 14 adjusts the direction of the nozzle, and sprays paint on the outer shell of the transformer in an inclined manner. When the lower turning rod 15 moves to disengage from the top beveled surface of the bottom turning wedge 9, under the action of the damping rotating shaft, the lower turning rod 15 stops moving in the horizontal direction. When the lower turning rod 15 continues to move downward and touches the point contact end of the first point contact switch 10, the first point contact switch 10 transmits a signal to the servo motor 7, and the servo motor 7 receives the signal and rotates in the reverse direction. When the lifting plate 4 moves to the top, the upper turning rod 13 moves in the horizontal direction through the beveled surface at the bottom end of the top turning wedge 11. The movement of the top turning wedge 11 drives the mounting fixing plate 8 to rotate, and at the same time drives the spray gun 14 to rotate the direction of the nozzle. When the upper turning rod 13 touches the point contact end of the second point contact switch 12, the servo motor 7 changes the rotation direction and drives the lifting plate 4 to move downward, and repeatedly moves up and down and swings left and right by the same angle in turn to spray paint on the outer shell of the transformer.

[0023] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
