Novel technology for assembling transformers

Abstract

The invention discloses a novel technology for assembling transformers. The invention relates to an assembly technology applied to small AC series transformers, and belongs to an improved technique of a transformer clasping and welding tooling. The technology mainly comprises a workbench (shown as Figure 1-10), an electrical box (shown as Figure 1-9), a boosting cylinder (shown as Figure 1-3), 6 welders and 6 welding guns (shown as Figure 1-7), a control panel (shown as Figure 1-5), and a transformer body positioning table (shown as Figure 1-6). A programmable controller PLC is configured to make all operation automatically executed by a program command. By improving a cylinder clamping workpiece, a cylinder tightening workpiece, a boosting cylinder prepressing workpiece, and a boosting clasping workpiece, and adding 6 welding guns to simultaneously weld the workpieces, the working environment is improved, the labor intensity is reduced, the laboring skill of the operating personnel is reduced, the labor efficiency is improved greatly, and the conventional required labor time is reduced from at least 30 seconds to 8.5 seconds, and the attractiveness of the welding technology and product quality are ensured.

Description

technical field [0001] The invention relates to an assembly process suitable for small AC series transformers, and belongs to an improved technology for transformer riveting and welding tooling. Background technique [0002] At present, the assembly tooling applied to small AC series transformers has a too simple structure and mainly includes two parts: manual adjustment bolts and cylinders. In the specific operation process, it is necessary to manually adjust the bolts to clamp and tighten the transformer body, and the air pressure generated by the cylinder is riveted to fasten the transformer body, and then welded. However, the air pressure generated by one cylinder is not enough, and it is necessary to continue to press the riveting buckle manually with an iron hammer. The above operation has the following disadvantages: [0003] 1. In the whole operation process, it is basically manual work, and the labor intensity of the operators is high. [0004] 2. After positioni...

Problems solved by technology

[0003] 1. In the whole operation process, it is basically manual work, and the labor intensity of the operators is high

[0004] 2. After the riveting of the transformer body is positioned, the workpiece needs to be welded. Therefore, only personnel with electric welding technology can operate, and the requirements for the operator's skills are relatively high.

On the one hand, manual force can easily lead to uneven force; on the other hand, it is easy to cause artificial damage to the transformer body, such as transformer distortion and deformation; finally, the positioning of the transformer body is not necessarily accurate
