Transformer lug welding equipment

Abstract

The invention discloses transformer lug welding equipment. The equipment structurally comprises a frame, a self-lubricating casing, an upper workpiece, a welding mechanism, a welding joint, a cast iron backing plate and a copper bar, the self-lubricating casing is fixedly welded to the right of the upper surface of the frame and is vertical to the frame, and the welding mechanism is movably connected an internal cavity of the self-lubricating casing. Related parts including a pulley connecting device, a touch connection mechanism and a movable lubrication mechanism are cooperated with each other, a bearing part of a connecting rod of the welding mechanism of the equipment can be lubricated in the process that a low-voltage lead of the transformer is welded to a lug connected to a bushing,internal wearing and friction of parts including the bearing are reduced, the amount of daily maintenance is reduced, foreign matters are prevented from entering the internal of the bearing, the bearing is prevented from tarnishing and corrosion, the service life of related parts is prolonged, the normal welding efficiency of the welding mechanism is ensured, and the reliability of the equipment is improved effectively.

Description

technical field [0001] The invention relates to transformer lug welding equipment, which belongs to the technical field of welding equipment manufacturing. Background technique [0002] At present, lugs are commonly used to connect transformer low-voltage leads to bushings. One end of the lug is welded to the copper bar through phosphor copper, and the other end is connected to the conductive rod. In the part connected to the conductive rod, usually in order to ensure good contact, the lug should be tinned. However, due to the low melting point of solder and the high melting point of phosphor copper, it is easy to melt the tin on the lugs during the welding process of transformer lugs and copper bars, increasing the contact resistance in the assembly process. Transformer lug welding equipment for the problem of melting the tinned part of the lug during the welding process with the copper bar. [0003] However, in the prior art, in the process of welding the lug connecting ...
