The invention relates to the field of electrical machining equipment and discloses a lever lifting type copper bar busbar joint tinning device. The lever lifting type copper bar busbar joint tinning device comprises a base, a tin melting mechanism, a lever type copper bar lifting mechanism, a copper bar fixing mechanism and a copper bar wiping mechanism. The lever type copper bar lifting mechanism comprises a main bearing pillar, a lifting type main supporting frame and a lever type lifting adjusting mechanism. The main bearing pillar is vertically arranged on the base, and the lifting type main supporting frame is fixed in a clamping groove of the main bearing pillar. The lever type lifting adjusting mechanism comprises a lifting operation lever, a fulcrum of the lifting operation lever is connected to the main bearing pillar in a pivotal manner, and the tail end of the lifting operation lever is connected to the lifting type main supporting frame in a pivotal manner. The copper bar fixing mechanism is fixed to the lifting type main supporting frame. The tin welding mechanism is arranged on the base. By means of the lever lifting type copper bar busbar joint tinning device, tinning work can be semi-automatically conducted on a copper bar busbar joint, the work efficiency is high, the tinning effect is good, safety is good, in addition, the manufacturing cost is low, and popularization is facilitated.
