A positioner suitable for welding transformer oil tank

Abstract

The invention relates to a positioner suitable for transformer oil tank welding. The positioner comprises a base, a clamp device, a rotating device and a connecting device. The clamp device mainly comprises a hydraulic cylinder, a connecting rod, a connecting block, a thrust bearing, a push rod, first connection rods, supporting rods, positioning rods, positioning blocks and positioning rollers. The rotating device mainly comprises a servo motor, a coupler, a driving shaft, a driving gear, a large gear ring, a rotating shaft and tapered roller bearings. The connecting device mainly comprises a connecting plate, a connecting pin, a supporting plate, upper supporting rolling wheels and lower supporting roll wheels. The eight positioning rollers of the clamp device move to appropriate positions, so that positioning and clamping of a transformer oil tank supporting frame are achieved; rotation of the transformer oil tank supporting frame can be achieved through the large gear ring of the rotating device, and it is guaranteed that cooling fins on the four sides of a transformer can be installed and welded at a horizontal position. Thus, welding quality is guaranteed, and labor intensity of workers is relieved.

Description

technical field [0001] The invention relates to a positioner in the technical field of welding equipment, in particular to a positioner suitable for welding transformer oil tanks. Background technique [0002] Transformers play a vital role in all aspects of power generation, transmission, distribution, power conversion and power consumption. Driven by my country's huge investment in power grid transformation, rail transit system upgrades, urban subways, intercity high-speed rail and other projects, my country's transformer industry is showing a trend of rapid development. On the other hand, the level of transformer manufacturing is still low. At present, when welding the transformer oil tank, it is mainly turned over, assembled, and welded manually, which has high labor intensity, low efficiency, and difficult quality assurance. [0003] At present, the most researched welding positioners are used for the welding of large frames in construction machinery, as well as for t...

On the other hand, the level of transformer manufacturing is still low

At present, when the transformer oil tank is welded, it is mainly turned over, assembled, and welded manually, which is labor-intensive, low in efficiency, and difficult to guarantee quality.

[0003] At present, the most researched welding positioners are used for the welding of large frames in construction machinery, as well as for the welding of large pipe fittings and sealed tanks. There are few positioners that can be used for welding transformer oil tanks, and their structural forms are generally It is a rotary-tilt type, and it is inconvenient to locate and clamp it from the inside of the transformer oil tank frame
