Description

A transformer casing welding device Technical Field

[0001] This utility model relates to the field of transformer housing production, and in particular to a transformer housing welding device. Background Technology

[0002] Welding is a manufacturing process and technology that joins metals or other thermoplastic materials such as plastics by heating, high temperature or high pressure. There are many energy sources for modern welding, including gas flame, electric arc, laser, electron beam, friction and ultrasound, etc. Transformer shells require a welding device during production.

[0003] The applicant discovered through a search that a Chinese patent, "A Welding Device for Transformer Housing Production," with publication number "CN218476224U," primarily uses a filter screen and a water tank to filter and purify the fumes generated during welding, reducing harm to the environment and human health. By pulling the scraper laterally, the welding slag on the filter screen can be moved to the slag collection box, preventing the slag from clogging the filter screen. When the slag collection box is full of welding slag, the bottom cover can be opened to clean the slag. The through holes increase the contact area between gas and water, resulting in better purification. The sliding block allows the welding head to move laterally, increasing the functionality of the device. The motor drives the screw to rotate, which in turn drives the sliding block to move laterally, facilitating observation of the welded object and preventing burns during the welding process.

[0004] The aforementioned device, through a series of structural designs, can adsorb and purify the welding fumes generated during welding, preventing them from spreading into the air. However, the device still has shortcomings in practical applications: for example, adjusting the welding position of the transformer shell requires manual operation, which not only increases the labor intensity of the workers but also reduces welding efficiency. Summary of the Invention

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Example 1

[0023] As shown in Figures 1 to 5, a transformer housing welding device according to the first aspect of this utility model includes a workbench 1 and a mounting frame 4 fixedly connected to the top surface of the workbench 1. The top of the mounting frame 4 is provided with a welding part 5. An electric telescopic rod 6 is fixedly connected to the bottom surface of the inner wall of the workbench 1. A support plate 7 is fixedly connected to the top surface of the electric telescopic rod 6. A rotating component 2 is provided on the top surface of the workbench 1. The rotating component 2 includes a rotating disk 203. The bottom surface of the rotating disk 203 is rotatably connected to the top surface of the workbench 1. A flipping component 3 that can cause the transformer housing to flip is provided on the rotating disk 203.

[0024] The technical effects achieved by the above embodiments are as follows: by setting the rotating component 2 and the rotating disk 203 on the workbench 1, the transformer shell to be welded can be rotated around the circumference. The flipping component 3 set on the rotating disk 203 can be used to flip the clamped and fixed transformer shell around the circumference, thereby effectively avoiding the problem of relying entirely on manual operation when adjusting the welding position of the transformer shell. This not only improves the welding efficiency but also reduces the labor intensity of the workers, thus improving the practicality of the device.

[0025] Example 2

[0026] As shown in Figures 3 and 4, a transformer casing welding device includes all the contents of Embodiment 1. In addition, the rotating assembly 2 also includes an annular groove 204, which is formed on the top surface of the workbench 1. The inner wall of the annular groove 204 is rotatably connected to a limiting ring 205. The top surface of the limiting ring 205 is fixedly connected to the bottom surface of the rotating disk 203. The rotating assembly 2 also includes a connecting cylinder 201, the top end of which is fixedly connected to the bottom surface of the rotating disk 203. The bottom end of the connecting cylinder 201 is fixedly connected to a toothed ring 202. The rotating assembly 2 also includes a mounting cavity 207 formed inside the workbench 1. The bottom surface of the inner wall of the mounting cavity 207 is fixedly connected to a first motor 208. The output end of the first motor 208 extends into the interior of the workbench 1 and is fixedly connected to a transmission gear 206. One side of the transmission gear 206 meshes with one side of the toothed ring 202.

[0027] The technical effect achieved by the above embodiment is as follows: when it is necessary to control the rotation and adjustment of the transformer housing position, the first motor 208 is started, and the first motor 208 can cause the transmission gear 206 to rotate. Under the action of the rotation of the transmission gear 206, the gear ring 202 can drive the connecting cylinder 201 and the rotating disk 203 to rotate, thereby achieving the effect of controlling the rotation and adjustment of the welding position of the transformer housing. The rotating disk 203 can be limited by setting the annular groove 204 and the limiting ring 205.

[0028] Example 3

[0029] As shown in Figures 2 and 5, a transformer casing welding device includes all the components of Embodiment 2. Furthermore, the flipping assembly 3 includes two support plates 301, the bottom surfaces of which are fixedly connected to the top surface of the rotating disk 203. The flipping assembly 3 also includes a second motor 303, one side of which is fixedly connected to one side of one of the support plates 301. The output end of the second motor 303 passes through the corresponding support plate 301. A controller 304 is fixedly connected to the bottom surface of the second motor 303, and the controller 304 is electrically connected to the second motor 303. The flipping assembly 3 also includes an extension cylinder 305. The outer wall of the extension cylinder 305 is slidably connected to the inner wall of one of the support plates 301. The inner wall of the extension cylinder 305 is threaded with a lead screw 306. One end of the lead screw 306 extends to one side of the surface of the corresponding support plate 301 and is fixedly connected to a handle 308. The rod wall of the lead screw 306 is rotatably connected to a bracket 307 through a bearing. One side of the bracket 307 is fixedly connected to one side of the corresponding support plate 301. The flipping assembly 3 also includes two electromagnetic blocks 302. One side of one electromagnetic block 302 is fixedly connected to the output end of the second motor 303, and one side of the other electromagnetic block 302 is rotatably connected to one end of the extension cylinder 305.

[0030] The technical effect achieved by the above embodiment is as follows: When it is necessary to fix the transformer shell, the transformer shell is first placed on the support plate 7, and then the screw 306 is rotated by rotating the handle 308. When the screw 306 rotates, the extension cylinder 305 can be moved towards the shell until the opposite side of the two electromagnetic blocks 302 contacts the opposite side of the shell. Then the handle 308 is stopped, and the two electromagnetic blocks 302 are energized so that the two electromagnetic blocks 302 have adsorption capacity.

[0031] When it is necessary to flip the transformer housing to adjust the welding position, first control the electric telescopic rod 6 to retract downwards, so that the support plate 7 can release its support on the housing. Then start the second motor 303. After the second motor 303 starts, it rotates slowly, which can drive the clamped and attracted transformer housing to flip, thus solving the problem of having to rely entirely on workers to adjust the welding position.

[0032] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
