Abstract

The invention discloses a compound gantry milling machine which comprises a machine body and a working table, wherein a guide rail is arranged on the machine body; the working table is arranged on the guide rail and slides along the guide rail; framework-type vertical column structures are arranged on both sides of the machine body; a cross beam frame is arranged between the two vertical columns;a sliding seat is suspended on the cross beam frame; a milling and boring head capable of stretching longitudinally is arranged in the sliding seat; the vertical columns have hollow framework-type structures; guide rails are arranged on two sides, relative to the inner side surface, of each framework; a sliding saddle is arranged between the two sides of each framework; two sides of the sliding saddle are connected with the four guide rails arranged on the two sides of each framework in a sliding way; a ram is arranged in the sliding saddle; and a main shaft with a horizontal milling head is arranged in the ram. By the compound gantry milling machine, as the four guide rails arranged on the two vertical columns are used for supporting the weight of the sliding saddles and the rams, the positioning precision, the coaxiality and the whole rigidity of lateral machining of the compound gantry milling machine are improved; meanwhile, the milling and boring head arranged on the cross beam frame can machine the upper side of the side faces of a part, so the lateral machining precision is improved.

Description

technical field [0001] The invention relates to the field of milling machines, in particular to the structure of a compound gantry milling machine. Background technique [0002] The bed both sides of existing gantry milling machine form portal frame by column and beam frame, and beam frame can do lifting motion along the guide rail on the column of both sides. There are 1 to 2 milling heads with vertical spindles on the beam frame, and the milling heads can move laterally along the guide rail of the beam frame. A ram is hung on one side of the column on both sides, and a milling head with a horizontal spindle is installed in the ram, and the ram drives the milling head to move up and down along the guide rail of the column. Since the ram is hung on one side of the column, the self-weight of the ram will inevitably affect the positioning accuracy of the side machining of the gantry milling machine, and has a greater impact on the rigidity of the gantry milling machine. Con...
