Transverse multi-drill-rig drilling machine capable of automatically rotating workpiece

The invention discloses a transverse multi-drill-rig drilling machine capable of automatically rotating a workpiece. The transverse multi-drill-rig drilling machine comprises a rack provided with a working platform, and an electric control box and a hydraulic oil tank are arranged below the working platform. The transverse multi-drill-rig drilling machine is characterized in that drill rig assemblies and a reduction gearbox are arranged on the working platform, and the reduction gearbox is arranged at one sides of the drill rig assemblies, a turn table is arranged on the reduction gearbox, a stepping motor is arranged at one side of the reduction gearbox, and a transmission mechanism in the reduction gearbox is driven by the stepping motor and drives the turn table to rotate; an enclasping hoop and an enclasping hoop hydraulic cylinder are installed on the turn table, a workpiece frame is installed on the turn table and provided with a workpiece handle and the workpiece, a turnover oil cylinder is installed in the turn table and connected with the workpiece handle at the top of the turn table, the workpiece can be drilled transversely through multiple drill rigs and automatically rotated through the rotating table just by clamping the workpiece through the transverse multi-drill-rig drilling machine, transverse drill hole machining on the multi-hole disc part can be finished at the same time, the production efficiency is improved, and the labor intensity of workers is relieved.
