Abstract

The invention relates to the technical field of machine tools, in particular to a viaduct type portal machine tool high in rigidity, strength and stability. The machine tool structurally comprises a base, a first bridge base, a second bridge base, a first linear rail, a second linear rail and a Y-axis feeding system, wherein the first bridge base and the second bridge base are arranged on the twosides of the base respectively, the first linear rail is arranged on the first bridge base, the second linear rail is arranged on the second bridge base, and the two ends of the Y-axis feeding systemare connected with the first linear rail and the second linear rail slidingly respectively. The Y-axis feeding system comprises a lead screw base, a first shoulder base, a second shoulder base, a leadscrew and a motor, wherein the first shoulder base and the second shoulder base are connected to the two sides of the lead screw base respectively, the lead screw is arranged on the lead screw base,and the motor is arranged at the rear end of the lead screw base and in driving connection with the lead screw. The first shoulder base is connected with the first linear rail slidingly. The second shoulder base is connected with the second linear rail slidingly. The viaduct type portal machine tool has the advantages of being low in cost and high in running precision. The strength, rigidity and stability of the base, the Y-axis feeding system and the whole machine can be improved, and high-speed machining can be ensured.

Description

technical field [0001] The invention relates to the technical field of processing machine tools, in particular to a viaduct type gantry processing machine tool with good rigidity, strength and stability. Background technique [0002] The viaduct-type gantry processing machine tools in the prior art, such as the viaduct-type gantry processing machine tools produced by Litz and Baide in Taiwan, China, and DMG in Germany, all adopt hollow-out design in the middle of the bridge seat of the processing center, and the transmission mechanism is installed on the sides. With this base hollow design, the bridges on both sides are only connected by the rear wall panels, which has the defect of insufficient rigidity. Moreover, the base is hollowed out, so that the Y-axis feed system needs to adopt dual servo synchronous control technology, that is, two sets of servo motor drives, two sets of double rack and pinion transmissions to eliminate transmission gaps and two sets of absolute en...
