Abstract

A compound gantry machine tool comprises a body (1) and a worktable (2). A guide rail (3) is arranged on the body (1). The worktable (2) is arranged on the guide rail (3) and slides along the guide rail (3). Two sides of the body (1) are each provided with a frame-shaped column structure (4). A beam support (5) is arranged between two columns (4). A slide seat (7) is hung on the beam support (5). A vertically telescopic boring and milling head (6) is arranged in the slide seat (7). The column (4) is of a hollow frame-shaped structure. Two sides of opposite inner side surfaces on two sides of the frame are each provided with a guide rail (41). A slide saddle (8) is arranged between the two sides of the frame. Two sides of the slide saddle (8) are slidably connected to four guide rails (2) disposed on the two sides of the frame. A ram (9) is mounted in the slide saddle (8). A spindle (10) having a horizontal milling head is arranged in the ram (9). In the compound gantry milling machine, the four guide rails (2) arranged on the two columns are used to bear the weight of the slide saddle and the ram, so as to improve the positioning accuracy, the concentricity, and the overall rigidity of side machining of the compound gantry milling machine. Meanwhile, the boring and milling head arranged on the beam support can perform machining above a side surface of a component, thereby improving the accuracy of side machining.

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...
