Abstract

The invention discloses a copper busbar welding tool for new energy vehicles. The copper busbar welding tool comprises a connecting bracket, a horizontal mounting plate, a vertical mounting plate anda positioning cylinder. The horizontal mounting plate is installed on the connecting bracket, and the vertical mounting plate is installed on the horizontal mounting plate. The positioning cylinder isinstalled on the vertical mounting plate, the positioning cylinder is connected with a supporting seat, the supporting seat is connected with a front and rear feeding cylinder, the front and rear feeding cylinder penetrates through the supporting seat to be connected with a guide rod, the middle of the guide rod is slidably connected with a connecting plate, and the guide rod is connected with aclamp. The clamp includes a sheet and a supporting rod, and the upper edge of the supporting rod and a jaw opening are on the same horizontal plane. According to the copper busbar welding tool for newenergy vehicles, the feed of a copper busbar can be adjusted in up and down, left and right, front and rear directions, the back side of a faying surface is clamped by a jaw, the supporting rod bearsthe weight of the remaining copper busbar to prevent the remaining copper busbar from bending due to gravity during welding, and the occurring of vibration at the time of copper busbar welding can beeffectively avoided.

Description

technical field [0001] The invention relates to the field of copper bar welding tooling, and more specifically relates to a copper bar welding tooling and a welding machine for new energy vehicles. Background technique [0002] Copper bar soft connection is a soft conductive device for new energy vehicle power batteries. It uses the elasticity of the soft expansion joint to protect it from breaking the switch or busbar due to short circuit or thermal expansion and contraction. Unrestricted, the soft connection of copper bars is easy to install and has strong flexibility, especially its fast heat dissipation and good electrical conductivity, and it is mostly used for the electrical conduction of lithium battery modules for new energy vehicles. The power battery consists of multiple batteries stacked in series. In order to increase the cruising range, new energy electric vehicles need a large number of lithium battery combination modules, each module is composed of several ba...
