Aluminum busbar milling machine

The utility model provides a milling machine which is used for milling the busbar when repairing the electrolytic tanks in each electrolytic aluminium factory. The feed motion and the primary motion of the milling are realized by two electric motors. One feed electric motor drives a speed reducer and a strip of elevating screw, and the primary electric motor drives a milling cutter disc to move. The primary electric motor is installed on a small carriage apron and moves forwards and backwards to feed following the small carriage apron, and also moves upwards and downwards following the small carriage apron to realize the feed motion. The power of the upper and lower feed motion of the small carriage apron originated from the feed electric motor. All the mechanical components are installed on the machine frame, and the electric apparatus control portion is installed inside a single power distribution box and is connected by a cable and the mechanical part. The milling machine is hanged to move by an overhead traveling carriage inside the repairing factory building, after achieving the position, the milling machine is hanged on the position which needs to be milled and fixed by a hook and a positioning block. The utility model has the advantages of reasonable structure design, compactness, small volume and convenient motion. The milling machine can proceed with the long distance remote operation, the safety performance is reinforced largely, and the repairing quality and efficiency of aluminum busbar is also raised effectively.
