The invention discloses a multifunctional robot for mechanical part production. The multifunctional robot for mechanical part production comprises a device body, wherein the device body comprises a protective shell, wherein a placing plate is arranged at the upper end of the interior of the protective shell; the interior of the placing plate is fixedly connected to first hydraulic cylinders; the upper ends of the first hydraulic cylinders are fixedly connected to a baseplate; a first sliding chute is formed inside the baseplate; the two sides of the first sliding chute are fixedly connected tosecond hydraulic cylinders; one ends, far away from the inner side of the baseplate, of the second hydraulic cylinders are fixedly connected to first sliding blocks; and the first sliding blocks areconnected to the first sliding chutes in a sliding manner. The placing plate is arranged in the protective shell of the multifunctional robot, and a transverse pipe with spray heads is arranged rightabove the placing plate, thereby facilitating the clearing of chippings on the surface of the part and the cooling of the part; a water storage tank is arranged right below the placing plate of the multifunctional robot; a filtering tank with a magnet plate is arranged inside the water storage tank, thereby facilitating the recovery of the chippings cleared down from the part; and the multifunctional robot for mechanical part production saves time and labor.
