Problems solved by technology
[0003] At present, the following defects usually exist in the welding of metal bellows type oil conservator: 1. When the traditional welding tool clamps the oil conservator shell and the side plate on which the bellows is installed, the alignment degree of the joint is often passed Manually distinguish, and since the metal bellows is installed in the center of the side plate of the oil conservator, the weight of the metal bellows will affect the position of the side plate of the oil conservator when welding the side plate, and the welding position is prone to shift during manual welding lead to poor welding effect; 2. The traditional welding tool cannot guarantee the tightness between the oil conservator shell and the side plate with the bellows installed, resulting in a gap between the oil conservator shell and the side plate with the bellows installed after welding. There are gaps, which affect the working effect of the oil conservator

The invention relates to the technical field of metal bellows oil conservator welding, in particular to a metal bellows type oil conservator manufacturing and welding tool for transformers, including a base, a limiting device and an alignment device. The upper end of the base is equipped with a limiting device, Alignment devices are symmetrically arranged on the front and rear sides of the right end of the limit device; the present invention can solve the problem that due to the influence of the weight of the metal bellows, the welding position is prone to shift during manual welding and the welding effect will deteriorate, and the traditional welding tool cannot guarantee oil The degree of closeness between the pillow shell and the side plate on which the bellows is installed; the present invention designs a tooling machine that clamps and aligns the oil conservator shell and the side plate on the side where the bellows is installed, so that The outer wall of the oil conservator shell is aligned with the joint of the side plate where the bellows is installed, and at the same time, the problem of gaps between the oil conservator shell and its side plate after welding is avoided.
Description
technical field [0001] The invention relates to the technical field of metal bellows oil conservator welding, in particular to a manufacturing and welding tool for transformer metal bellows type oil conservator. Background technique [0002] A transformer is a device that uses the principle of electromagnetic induction to change the AC voltage, and a three-phase transformer is one of the transformers that are widely used in imported important equipment, precision machine tools, mechanical and electronic equipment, rectifiers and lighting; three-phase transformers are mainly It is composed of transformer box, high-voltage insulating bushing, low-voltage insulating bushing, oil conservator and heat dissipation pipe, among which the oil conservator is an important part of the three-phase transformer, which plays the role of oil storage and replenishment, ensuring the oil tank of the transformer Filled with oil, the oil conservator can also slow down the deterioration of transfo...
