[0030] Obviously, the described embodiments are only part of the embodiments of the utility model, not all embodiments, based on the embodiments of the utility model, the other embodiments obtained by the person skilled in the art without creative labor all belong to the protection scope of the utility model.Various technical features in the utility model can be combined interactively without mutual contradiction and conflict.

[0031] Referring to Figure 1 And Figure 2 The utility model discloses an auxiliary tool for box cover welding can realize the fixed function when the box cover 500 welding, especially suitable for the box cover 500 welding of single-phase box-type transformer, and, through multidirectional adjustment can realize tool size adjustment, to adapt to the welding of different size box cover 500, higher safety.

[0032] In the embodiment, the auxiliary tool for box cover welding includes two main pressure plates 100 and two auxiliary pressure plates 200, wherein the two main pressure plates 100 are arranged in parallel with each other, referring to Figure 3 The lower surface of each main pressure plate 100 is respectively provided with a first auxiliary adjusting groove 110 and a second auxiliary adjusting groove 120, and the first auxiliary adjusting groove 110 and the second auxiliary adjusting groove 120 on the same main pressure plate 100 are arranged along the length direction of the main pressure plate 100, and the first auxiliary adjusting groove 110 and the second auxiliary adjusting groove 120 respectively penetrate the two side faces of the main pressure plate 100 along the width direction.

[0033] The main platen 100 and the auxiliary platen 200 are both arranged perpendicular to the vertical direction, and the main platen 100 is perpendicular to the auxiliary platen 200. The extension direction of the main platen 100 is the first direction, and the extension direction of the auxiliary platen 200 is the second direction. For the convenience of description, the left-right direction is referred to as the first direction, and the front-back direction is referred to as the second direction. The two main platens 100 are respectively extended in the left-right direction, and the two auxiliary platens 200 are respectively extended in the front-back direction.

[0034] The two main pressure plates 100 are arranged parallel to each other, with their first auxiliary adjustment slots 110 arranged in a front-to-back direction, and their second auxiliary adjustment slots 120 arranged in a front-to-back direction. The two auxiliary pressure plates 200 are arranged parallel to each other, with the front and rear ends of one auxiliary pressure plate 200 slidingly connected to the first auxiliary adjustment slots 110 of the two main pressure plates 100, and the front and rear ends of the other auxiliary pressure plate 200 slidingly connected to the second auxiliary adjustment slots 120 of the two main pressure plates 100.

[0035] The two main pressure plates 100 and the two auxiliary pressure plates 200 together form a "well" structure. When in use, the two main pressure plates 100 and the two auxiliary pressure plates 200 are pressed against the top of the box cover 500. The middle part of the "well" structure is in the shape of a "mouth". The main pressure plate 100 can slide in the front-to-back direction relative to the auxiliary pressure plate 200, and the auxiliary pressure plate 200 can slide in the left-to-right direction relative to the main pressure plate 100, thereby adjusting the size of the "mouth" shape to adapt to box specifications of different specifications, which is universal. The mutual restriction of the two main pressure plates 100 and the two auxiliary pressure plates 200 can also avoid the unstable stacking between the main pressure plates 100 or the auxiliary pressure plates 200, which is safer. After the box cover welding auxiliary tooling is installed and fixed above the box cover 500, during the welding process, the four edges of the box cover 500 do not need to change the position of the box cover welding auxiliary tooling, which reduces the tedious operations during the welding process and is more conducive to improving the production efficiency of the product.

[0036] In some embodiments, reference Figure 4 The upper surface of each auxiliary platen 200 is provided with a first main adjustment groove 210 and a second main adjustment groove 220. The first main adjustment groove 210 and the second main adjustment groove 220 on the same auxiliary platen 200 are arranged in the front-to-back direction. The first main adjustment groove 210 and the second main adjustment groove 220 respectively penetrate the left and right side surfaces of the auxiliary platen 200. The first main adjustment grooves 210 on the two auxiliary platens 200 are arranged in the left-right direction, and the second main adjustment grooves 220 on the two auxiliary platens 200 are arranged in the left-right direction.

[0037] When the sub-pressing plates 200 and the main pressing plates 100 are installed, the first sub-adjusting grooves 110 and the second sub-adjusting grooves 120 of one of the main pressing plates 100 are respectively clamped with the first main adjusting grooves 210 of the two sub-pressing plates 200, and the first sub-adjusting grooves 110 and the second sub-adjusting grooves 120 of the other main pressing plate 100 are respectively clamped with the second group of adjusting grooves of the two sub-pressing plates 200.

[0038] It can be understood that by setting the first main adjusting grooves 210 and the second main adjusting grooves 220, the moving range of the two main pressing plates 100 in the front-rear direction can be limited, and the problem of the distance between the two sub-pressing plates 200 being too close can be avoided, so as to ensure the pressing effect on the edges of the box cover 500. In addition, the first sub-adjusting grooves 110 and the second sub-adjusting grooves 120 can limit the moving range of the two sub-pressing plates 200 in the left-right direction, and the problem of the distance between the two sub-pressing plates 200 being too close can be avoided, so as to ensure the pressing effect on the edges of the box cover 500.

[0039] In some embodiments, the distance between the two sub-pressing plates 200 ranges from greater than or equal to 450 mm to less than or equal to 700 mm, that is, the distance between the mutually close wall surfaces of the first sub-adjusting grooves 110 and the second sub-adjusting grooves 120 on the same main pressing plate 100 is 450 mm, and the distance between the mutually far wall surfaces minus the width of the two sub-pressing plates 200 is 700 mm. By such arrangement, the size of the box cover 500 of most distribution single-phase box transformers can be adapted.

[0040] In some embodiments, the distance between the two main pressing plates 100 ranges from greater than or equal to 300 mm to less than or equal to 550 mm, that is, the distance between the mutually close wall surfaces of the first main adjusting grooves 210 and the second main adjusting grooves 220 on the same sub-pressing plate 200 is 300 mm, and the distance between the mutually far ends minus the width of the two main pressing plates 100 is 550 mm. By such arrangement, the size of the box cover 500 of most distribution single-phase box transformers can be adapted.

[0041] In some embodiments, the mutually far ends of the first main adjusting grooves 210 and the second main adjusting grooves 220 are open, that is, the distance between the front and rear ends of the sub-pressing plate 200 minus the width of the two main pressing plates 100 is 550 mm. By such arrangement, the installation and connection of the main pressing plates 100 are more convenient.

[0042] In some embodiments, the first sub-adjusting groove 110 and the second sub-adjusting groove 120 on the same main pressing plate 100 are provided with a circular arc transition at the lower end of the distal end away from each other. When the box cover welding auxiliary tool of the embodiment is installed, the main pressing plate 100 is clamped above the box body 400, the circular arc surface can be in contact with the side wall surface of the box body 400, which can avoid the sharp corners of the lower end of the first sub-adjusting groove 110 and the second sub-adjusting groove 120 from cutting the box body 400, thereby protecting the box body 400 to a certain extent.

[0043] In some embodiments, each main pressing plate 100 is provided with two hooks 300, and the two hooks 300 are respectively arranged at the left and right ends of the main pressing plate 100. Moreover, the two hooks 300 are both arranged in a downward extending manner.

[0044] It can be understood that the side wall surface of the box body 400 is generally provided with a hanging ear 410 structure. When the box cover welding auxiliary tool of the embodiment is installed on the box body 400, the hook 300 can be connected and fixed with the hanging ear 410 structure on the side surface of the box body 400, so that the main pressing plate 100 and the sub-pressing plate 200 can exert a downward pressing force on the box cover 500, thereby realizing the pressing of the box cover 500 without additional labor, and the welding operation of the box cover 500 can also be performed by only one worker.

[0045] In some embodiments, the hook 300 is made of an elastic rubber ring. The upper end of the elastic rubber ring is sleeved on the left and right ends of the main pressing plate 100, and the lower end of the elastic rubber ring is sleeved on the hanging ear 410 of the box body 400. Through the elastic action of the elastic rubber ring, a downward pressure is exerted on the main pressing plate 100. Moreover, the elastic rubber ring can move along the length direction of the main pressing plate 100, so as to adapt to box bodies 400 of different lengths. When the box body 400 is relatively long, the two elastic rubber rings located on the same main pressing plate 100 move away from each other. When the box body 400 is relatively short, the two elastic rubber rings located on the same main pressing plate 100 move close to each other.

[0046] However, the elastic action of the elastic rubber ring exerts limited pressure on the main pressing plate 100, and the pressing effect of the box cover 500 may not meet the preset requirements.

[0047] In the embodiment, with reference to Figure 3 The left and right ends of each main pressing plate 100 are respectively provided with an adjusting hole 130, and each adjusting hole 130 extends in the left-right direction. The hook 300 is made of a rigid material and is slidably connected in the adjusting hole 130. In this way, the box bodies 400 of different lengths can be adapted, and better pressing effect of the box cover 500 can be achieved.

[0048] In the embodiment, the adjusting hole 130 is a waist-shaped hole.

[0049] In some embodiments, with reference toFigure 5 The hook 300 comprises a hook portion 310, a rod portion 320, and a locking portion. The locking portion is connected to the upper end of the rod portion 320 and is clamped above the main pressing plate 100. The hook portion 310 is connected to the lower end of the rod portion 320. It can be understood that the rod portion 320 is arranged in the adjusting hole 130 in the up-down direction and can move along the length direction of the adjusting hole 130, so as to adjust the left-right position of the hook portion 310 to adapt to the box body 400 of different lengths.

[0050] Due to the limiting effect of the main pressing plate 100, the locking portion cannot fall downward through the adjusting hole 130, thereby ensuring the stability of the hook 300.

[0051] In some embodiments, the upper end of the rod portion 320 is provided with an adjusting thread 321, which is an external thread. The locking portion is a nut 330, which has an internal thread. In use, the nut 330 is sleeved on the outer periphery of the rod portion 320, and the internal thread of the nut 330 cooperates with the adjusting thread 321.

[0052] It can be understood that rotating the nut 330 can adjust the up-down position of the nut 330 on the rod portion 320, so as to adjust the distance between the nut 330 and the hook portion 310. When the hook 300 is installed on the main pressing plate 100, the distance between the hook portion 310 and the main pressing plate 100 can be adjusted, thereby adapting to the box body 400 with different height positions of the lug 410, further improving the versatility of the box cover welding auxiliary tool, and improving the pressing degree of the box cover 500.

[0053] In some embodiments, the hook 300 further comprises a gasket 340, which is sleeved on the outer side of the rod portion 320 and is clamped at the position between the nut 330 and the upper end surface of the main pressing plate 100. The gasket 340 can buffer the pressure between the nut 330 and the main pressing plate 100, prevent loosening, effectively protect the nut 330 and the main pressing plate 100, and prolong the service life of the parts.

[0054] In some embodiments, the hook portions 310 of the two hooks 300 located on the left side of the two main pressing plates 100 are arranged opposite to each other, and the hook portions 310 of the two hooks 300 located on the right side of the two main pressing plates 100 are arranged opposite to each other. That is, the hook portions 310 of the two hooks 300 located on the front side of the main pressing plate 100 are arranged forward, and the hook portions 310 of the two hooks 300 located on the rear side of the main pressing plate 100 are arranged rearward. In this way, the stress on the front and rear sides of the box cover 500 is uniform, avoiding the situation that one side of the box cover 500 is warped, and improving the welding accuracy.

[0055] In some embodiments, the nut 330 is a spanner nut, which can be conveniently rotated by hand or with a tool.

[0056] In the embodiment, the main pressing plate 100 and the auxiliary pressing plate 200 are made of electrical laminated wood, which meets the required strength and achieves the effects of lightness and easy operation.

[0057] When the box cover welding auxiliary tool is used to assist in welding, the main pressing plate 100 and the auxiliary pressing plate 200 are only needed to be installed and adjusted on the box cover 500 according to the size of the box cover 500 and the size of the box body 400, and the position of the hook 300 is adjusted according to the position of the lug 410 of the box body 400, so that the box cover 500 can be pressed tightly. The production operation time can be reduced, the labor cost can be reduced, and the operation accuracy can be improved. In addition, the box cover welding auxiliary tool is convenient to carry, flexible and simple to operate, has high universality, reduces production waste, and improves production efficiency.
