Description

Technical Field

[0001] The utility model relates to the technical field of transformer housing processing, in particular to a processing tooling for transformer housings. Background Technique

[0002] The transformer housing is an important part of the transformer. It is usually a structure made of metal (such as steel or aluminum) or other non-metallic materials, and is used to wrap and protect the internal components of the transformer.

[0003] The main functions of the transformer housing include: electrical safety protection: the housing can prevent people from directly contacting the high-voltage components inside the transformer, thus avoiding electric shock accidents. Environmental isolation: the transformer may generate certain noise, heat and electromagnetic radiation during operation. Heat dissipation function: a large amount of heat is generated when the transformer is running. If the heat cannot be dissipated in time, the temperature of the transformer will rise, affecting its performance and service life. Mechanical protection: the housing can also provide mechanical protection for the transformer to prevent it from being physically damaged by external impacts, vibrations, etc. Dust and water protection: for some transformers installed outdoors, the housing also needs to have the function of dust and water protection to ensure that the transformer can still work normally in a harsh environment.

[0004] Among them, when processing the transformer housing, the surface of the transformer housing after welding is subjected to spray painting processing to ensure the subsequent service life of the transformer housing.

[0005] However, in actual use of the existing technology, during the spray painting processing of the welded transformer housing, due to the relatively large volume and weight of the transformer housing, it is more cumbersome and inconvenient to spray paint on the surface of the transformer housing, thus affecting the processing efficiency of the transformer housing.

[0018] After the outer surface of the transformer housing is painted, the moving platform will continue to drive the transformer housing to move linearly backward out of the painting shed. When the moving platform continues to move linearly backward, the moving platform will drive the pressing pad to move linearly backward. When the pressing pad moves linearly backward, it will press the limit pressing switch. When the limit pressing switch is pressed, the first driving motor and the second driving motor can be controlled to stop rotating through the pressing action of the limit pressing switch, so that the transformer housing stops moving linearly backward and rotating, thus realizing the limit protection for the movement of the transformer housing while facilitating the painting process of the outer surface of the transformer housing.

[0025] A first driving motor 6 is fixedly installed on the outer wall at the rear end of the moving groove 1. A transmission lead screw 7 is fixedly installed on the inner side transmission shaft part of the first driving motor 6. The front and rear ends of the transmission lead screw 7 are respectively rotationally connected to the inner walls at the front and rear ends of the moving groove 1 through rotating shafts. Support platforms 8 are provided on the inner walls on both sides of the moving groove 1, and the number of the support platforms 8 is two, which are symmetrically distributed on the inner walls on both sides of the moving groove 1. A limiting guide rail 9 is fixedly installed on the upper end of the support platform 8. A moving platform 10 is limited and fitted and movably connected to the upper end of the limiting guide rail 9. A lead screw nut 11 is fixedly installed at the bottom of the moving platform 10, and the outer surface of the transmission lead screw 7 is threadedly connected through the middle part of the lead screw nut 11. A second driving motor 12 is fixedly installed at the side end of the bottom of the moving platform 10. The upper end transmission shaft part of the second driving motor 12 is rotationally connected through the rotating shaft to the side end of the moving platform 10. A transmission gear 13 is fixedly installed on the upper end transmission shaft part of the second driving motor 12. A transmission gear ring 14 is meshed and connected to the side end of the transmission gear 13. A rotating bottom platform 15 is fixedly installed in the middle of the transmission gear ring 14, and the rotating bottom platform 15 is rotationally connected to the upper end middle part of the moving platform 10 through a rotating shaft. A placing platform 16 is fixedly installed on the upper end of the rotating bottom platform 15. The required transformer housing 17 to be painted is fitted and movably connected to the upper end of the placing platform 16, and anti-slip stripes for anti-slip of the transformer housing 17 are provided on the upper end of the placing platform 16;

[0026] On the upper sides of the inner walls at the front and rear ends of the moving groove 1, there are two limit pressure switches 18 fixedly installed by inlaying. The two limit pressure switches 18 are symmetrically distributed on the upper sides of the inner walls at the front and rear ends of the moving groove 1. The limit pressure switches 18 are electrically connected to the first driving motor 6 and the second driving motor 12 respectively through wires. In the middle of the front and rear ends of the moving platform 10, there are pressing pads 19 fixedly installed, and the pressing pads 19 and the limit pressure switches 18 are on the same horizontal line.

[0027] Working principle: When in use, the utility model hoists the transformer shell 17 to be spray-painted onto the upper end of the placement table 16. When the transformer shell 17 is hoisted to the upper end of the placement table 16, the first driving motor 6 is controlled to start. When the first driving motor 6 starts, it drives the transmission lead screw 7 to rotate. When the transmission lead screw 7 rotates, it drives the lead screw nut 11 to move backward due to the acting force generated by the through-threaded connection with the outer curved surface of the transmission lead screw 7. When the lead screw nut 11 moves backward, it drives the moving platform 10 to move backward along the upper end of the limit guide rail 9. When the moving platform 10 moves backward in a straight line, it synchronously drives the transformer shell 17 on the upper end of the placement table 16 to move backward in a straight line. When the transformer shell 17 moves backward in a straight line, the transformer shell 17 will push open the flexible shielding curtain 3 and move backward in a straight line into the spray-painting shed 2. When the transformer shell 17 moves backward in a straight line into the spray-painting shed 2, the external paint supply pipeline is controlled to start. When the external paint supply pipeline starts, the outer surface of the transformer shell 17 inside the spray-painting shed 2 is spray-painted through the paint spray head 4. When the paint spray head 4 sprays the outer surface of the transformer shell 17, the second driving motor 12 is controlled to start. When the second driving motor 12 starts, it drives the transmission gear 13 to rotate. When the transmission gear 13 rotates, it drives the rotating bottom platform 15 to rotate due to the acting force generated by the meshing connection between the side end of the transmission gear 13 and the transmission gear ring 14. When the rotating bottom platform 15 rotates, it drives the transformer shell 17 to rotate inside the spray-painting shed 2, so that the outer surface of the transformer shell 17 is evenly spray-painted, thus realizing the function of facilitating the spray-painting process of the outer surface of the transformer shell 17.

[0028] At the same time, after the outer surface of the transformer shell 17 is spray-painted, the moving platform 10 will continue to synchronously drive the transformer shell 17 to move backward in a straight line out of the spray-painting shed 2. When the moving platform 10 continues to move backward in a straight line, the moving platform 10 will drive the pressing pad 19 to move backward in a straight line. When the pressing pad 19 moves backward in a straight line, it will press the limit pressure switch 18. When the limit pressure switch 18 is pressed, the first driving motor 6 and the second driving motor 12 can be controlled to stop rotating through the pressing action of the limit pressure switch 18, so that the transformer shell 17 stops moving backward in a straight line and rotating, thus realizing the function of facilitating the spray-painting process of the outer surface of the transformer shell 17 and providing limit protection for the movement of the transformer shell 17 at the same time.
