Welding positioner for transformer oil tank framework and corrugated wall

Abstract

The invention discloses a welding positioner for a transformer oil tank framework and a corrugated wall. The welding positioner for the transformer oil tank framework and the corrugated wall comprisesa machine seat, an oil tank clamp and a rotation drive device. The oil tank clamp comprises a fixing frame, at least two supporting rods, a telescopic device, abutting plates and clamping devices connected with the abutting plates, wherein the supporting rods are connected with the telescopic device, the supporting rods are controlled to move on the fixing frame through the telescopic device, sothat a transformer oil tank is located and clamped to the oil tank clamp in a cavity. The clamping devices support the abutting rods to abut against protrusions of the transformer oil tank, and the transformer oil tank is limited from moving in the direction of the supporting rods. The rotation drive device is fixed to the machine seat and connected with the oil tank clamp. The rotation drive device drives the oil tank clamp to rotate to achieve position shifting. The welding positioner for the transformer oil tank framework and the corrugated wall is compact in structure and achieves accurateand convenient locating, the opening performance of the clamp is good, and loading and unloading of the workpiece are convenient.

Description

technical field [0001] The invention relates to the field of welding auxiliary equipment, in particular to a welding positioner applied to transformer oil tank skeletons and corrugated walls. Background technique [0002] The welding positioner is a special welding auxiliary equipment, which is suitable for the welding displacement of the rotary work, so as to obtain the ideal processing position and welding speed. It can be used in conjunction with manipulators and welding machines to form an automatic welding center, and it can also be used for workpiece displacement during manual operations. The particularity of the welding between the transformer oil tank frame and the corrugated wall is that the welding surface must be arranged horizontally. Because the corrugated wall is thin, if it is not arranged horizontally, the solution during welding will flow around, resulting in a decrease in welding quality. [0003] At present, the level of transformer manufacturing is still...
