[0024] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.

[0025] Embodiment 1

[0026] In order to solve the problem that manual operation is complicated and inconvenient when spraying transformer, please refer to Figs. 1-3The embodiment provides a spraying equipment for transformer shell production, which comprises a support 1 arranged in a processing area and used as a carrier to support structures arranged thereon. The support 1 is provided with a clamping assembly 2 used for clamping a transformer, the support 1 is provided with a moving assembly 3 used for adjusting the position of the clamping assembly 2, and the support 1 is further provided with a spraying assembly 4 used for processing the transformer. When the transformer is processed by spraying, the transformer is placed in the clamping assembly 2, the transformer can be lifted by clamping the transformer by the clamping assembly 2, the transformer can be rotated under the action of the moving assembly 3, and then the transformer is sprayed by the spraying assembly 4, so that when the transformer is sprayed, manual operation is not needed, the rotation speed and direction of the transformer are controlled, the spraying of the whole surface of the transformer is realized, the position is not needed to be frequently moved and the angle of the spray gun is not needed to be frequently adjusted, the labor intensity of workers is reduced, and the influence of paint on the health of workers during spraying is reduced.

[0027] When spraying the transformer, the worker needs to hold the spray gun and continuously spray around the transformer. The operation is complicated, increases the labor intensity of the worker, and cannot uniformly spray the surface of the transformer, affecting the production quality. Therefore, it is necessary to reduce the labor intensity of the worker during spraying and improve the production quality. The clamping assembly 2 includes a processing bin 21 fixedly installed on the support 1 and capable of being opened and closed. The processing bin 21 is used to seal the processing place when spraying the transformer, so that the paint cannot be directed out and splashed. The installation shell 22 is provided in the processing bin 21. The installation shell 22 serves as a carrier for carrying the structure arranged thereon. The T-shaped support block 23 is fixedly connected in the installation shell 22. The first sliding block 24 symmetrically arranged is slidingly connected to the length direction of the support block 23. The first sliding block 24 is used to push the clamping plate 27 close to or away from the transformer. The second sliding block 25 is slidingly connected to the width direction of the support block 23. The second sliding block 25 is used to drive the first sliding block 24. The rotating shaft 26 is rotatably connected between the first sliding block 24 and the second sliding block 25. The sizes of the installation shell 22 and the clamping plate 27 are slightly smaller than the processed transformer, so as to ensure that the transformer can be clamped and lifted without being blocked. The length of the rotating shaft 26 is greater than the distance between the installation shell 22 and the transformer, so as to ensure that the transformer can be clamped. The first sliding block 24 is fixedly connected with the clamping plate 27 at the end. The electric push rod 28 for driving the second sliding block 25 to slide is fixedly installed in the installation shell 22. The adjusting assembly 3 includes a connecting plate 31 slidingly installed in the processing bin 21. The installation shell 22 is rotatably installed in the connecting plate 31. The electric motor 32 for driving the installation shell 22 to rotate is fixedly installed on the connecting plate 31. The electric motor 32 serves as the power source for rotating the transformer. The air cylinder 33 for driving the connecting plate 31 to slide in the vertical direction is fixedly installed on the processing bin 21. The air cylinder 33 serves as the power source for adjusting the height of the transformer. When spraying the transformer, open the processing bin 21, place the transformer inside, and then close the processing bin 21. Then start the air cylinder 33, which drives the clamping plate 27 to drop into the interior of the transformer. Then start the electric push rod 28, which drives the first sliding block 24 to slide along the length direction of the support block 23 and close to the inner wall of the transformer to clamp it. Then the air cylinder 33 adjusts the appropriate spraying height, and the electric motor 32 drives the transformer to rotate during spraying, so that the spraying assembly 4 can uniformly spray the surface of the transformer, thereby realizing that manual operation is not needed during spraying. By controlling the rotating speed and direction of the transformer, the spraying of the entire surface of the transformer can be realized without frequent movement and adjustment of the angle of the spray gun, reducing the labor intensity of the worker and improving the work efficiency and the convenience of operation. The influence of the paint on the health of the worker during spraying is reduced, and the safety of the worker during spraying is improved.

[0028] Considering that the labor intensity is large when spraying the transformer artificially, and the uniformity of spraying cannot be guaranteed, the production quality of the transformer is affected, therefore, it is necessary to improve the uniformity of spraying, refer to Figs. 1-3The spraying assembly 4 comprises a plurality of outer spraying heads 41 symmetrically arranged and fixedly mounted on the inner wall of the processing chamber 21, a bottom spraying head 42 symmetrically arranged and slidably connected in the processing chamber 21, and a gear 43 rotatably mounted in the processing chamber 21. The gear 43 is used to drive the first rack 44, so that the bottom spraying head 42 can be close to or away from the transformer. The first rack 44 is fixedly connected to the bottom spraying head 42 on one side of the gear 43, and the second rack 45 is slidably connected to the gear 43 on the other side of the gear 43. The second rack 45 is fixedly mounted on the connecting plate 31 and is used to drive the gear 43, so that the first rack 44 can drive the bottom spraying head 42 to move. The bracket 1 is provided with a storage tank 46 for storing the sprayed paint, and the surface of the storage tank 46 is provided with a transparent display frame, so that the amount of paint inside can be directly observed, and the paint can be conveniently added in time to ensure normal spraying effect. The storage tank 46 is communicated with a pressurizing pump 47, and the pressurizing pump 47 is communicated with the outer spraying head 41 and the bottom spraying head 42. The pressurizing pump 47 is used to pressurize the paint, so that it can be delivered to the outer spraying head 41 and the bottom spraying head 42. The outer spraying head 41 has a gap larger than the rotation of the processed transformer, which can prevent the transformer from being collided when the transformer rotates, ensure the normal work of spraying, and improve the safety of spraying. The distance between the outer spraying heads 41 is uniform, which is matched with the size of the transformer, so that the surface of the transformer can be uniformly sprayed when the transformer is sprayed, and the shadow area generated during spraying is reduced. The distance between the bottom spraying heads 42 is uniform, which is matched with the size of the processed transformer. The bottom spraying head 42 is inclined at an angle of 45-60 degrees, which can ensure that the paint can be uniformly sprayed on the bottom surface of the transformer when the bottom of the transformer is sprayed, and the shadow area generated during spraying is reduced. When the cylinder 33 drives the transformer to lift, the second rack 45 slides under the driving of the connecting plate 31, the gear 43 drives under the driving of the second rack 45, and the first rack 44 drives the bottom spraying head 42 to approach the bottom of the transformer. When the transformer is lifted to the appropriate height, the outer spraying head 41 is located around the transformer, and the bottom spraying head 42 is located below the transformer. Then the pressurizing pump 47 is started, and the paint in the storage tank 46 can be sprayed out through the outer spraying head 41 and the bottom spraying head 42 under the driving of the pressurizing pump 47. The transformer is sprayed and processed under the rotation of the transformer, so that the transformer can be uniformly sprayed, and each surface of the transformer can be uniformly sprayed, including the side, the bottom and some corners that are difficult to reach. The uniform distribution of the coating is ensured, the local over-thickness or over-thin situation is avoided, the spraying quality and the appearance of the transformer are improved. And through the standardized operation of lifting and rotating the transformer, the spraying quality of each transformer can be consistent. The quality fluctuation caused by human factors and operation differences can be reduced.

[0029] Example 2

[0030] On the basis of the embodiment 1, considering that the inner wall surface of the transformer can be not completely flat, therefore, it is needed that the clamping plate 27 can be close to the inner wall surface of the transformer when clamping the transformer, and tightly close clamping, refer to Figs. 1-3 The clamping plate 27 is uniformly distributed with a plurality of installation grooves 271 in horizontal and vertical directions, and the close plate 272 is slidably connected in the installation groove 271, and the close plate 272 is used for close to the inner wall of the transformer. The rubber pad 273 is fixedly connected on the close plate 272, and the rubber pad 273 is used for reducing the influence caused by extruding the inner wall of the transformer when the close plate 272 is close to the inner wall, and can increase the friction between the close plate 272 and the inner wall of the transformer, and improve the firmness of clamping. The spring 274 is fixedly connected between the close plate 272 and the inner wall of the installation groove 271, and the spring 274 is used for limiting the close plate 272. When clamping the transformer, the close plate 272 can be close to the surface of the transformer under the driving of the clamping plate 27, and can be close to the inner wall under the action of the spring 274, and can be clamped, and the damage caused by clamping the transformer can be reduced under the action of the rubber pad 273, and the firmness of clamping the transformer and the production quality when spraying the transformer can be improved.

Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting, and the scope of the present application is defined by the appended claims rather than the above description, and therefore all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be included in the present application.
