[0012] The following will be combined with the drawings Figs. 1-3 Further detailed description of the present application.
[0013] A transformer oil tank cover welding positioning device, comprising a support 1, a top plate 2, a side support frame 3 and a edge support frame 4, the inside of the support 1 is provided with side frames 101 and cross frames 102, and limiting beams are installed between the cross frames 102; the side support frame 3 is slidably installed on the two sides of the support 1 through the side frames 101 and is used for supporting the oil tank cover laterally; the edge support frame 4 is slidably installed on one side of the support 1 through the cross frames 102 and is used for supporting the edge of the oil tank cover; the top plate 2 is installed on the top of the support 1, equidistant positioning holes are formed in the top of the top plate 2 and are used for fixing the oil tank cover; and support plates are installed on the top of the side support frame 3 and the edge support frame 4 through bolts and are used for increasing support stability.
[0014] Further, the side frames 101 and the cross frames 102 constitute an adjustable frame structure to adapt to oil tank covers of different sizes.
[0015] Further, the number and position of the positioning holes of the top plate 2 can be adjusted according to actual needs.
[0016] In specific implementation, first, the height of the side support frame 3 and the edge support frame 4 is adjusted according to the size of the transformer oil tank cover, so that the side support frame 3 and the edge support frame 4 are closely fitted with the edge of the oil tank cover, then the oil tank cover is placed on the support plates and is fixed through the positioning holes on the top plate 2, and next, welding work can be performed. In the welding process, the support 1, the side support frame 3 and the edge support frame 4 jointly constitute a stable support system to ensure that the oil tank cover does not displace or deform. After welding is completed, the fixing members in the positioning holes are loosened, and the oil tank cover can be easily removed.
[0017] The standard parts used in the utility model can be purchased from the market, the special-shaped parts can be ordered according to the description and the drawings, the specific connection mode of each part adopts the conventional means such as bolts, rivets and welding in the prior art, the machinery, parts and equipment adopt conventional models in the prior art, and the circuit connection adopts the conventional connection mode in the prior art, which will not be described in detail here.
[0018] Working principle: the working principle of the utility model mainly based on the principle of sliding adjustment and multi-point support. Through the sliding adjustment function of the side support frame 3 and the edge support frame 4, the adaptation to oil tank covers of different sizes is realized. At the same time, the positioning holes on the top plate 2 and the support plates jointly constitute a multi-point support system to ensure the stability and precision of the oil tank cover in the welding process. In the welding work, the support 1 serves as the support base of the whole device to provide a stable working environment.
