Background

In the prior art, the workpiece auxiliary supporting device produced by each deep hole machine tool enterprise is usually provided with a bracket body at the upper end of a trapezoidal screw, and the trapezoidal screw and the bracket body move up and down under the action of preventing the trapezoidal screw from rotating by a guide key by rotating a nut of the trapezoidal screw so as to adapt to the self-supporting requirements of workpieces with different outer diameters. The transmission of the existing workpiece auxiliary supporting device is completed only through the trapezoidal screw pair, and no other speed reducing mechanism exists, so that larger rotation torque is required to enable the trapezoidal screw and the bracket body to move up and down, and particularly, under the condition that a workpiece is rotated on the bracket body, larger rotation torque is required to enable the trapezoidal screw and the bracket body to move up and down. The adjustment of the auxiliary workpiece supporting device is usually completed manually, and the nut of the trapezoidal screw is arranged below the lower bracket body, so that the operation space is limited, and therefore, the auxiliary workpiece supporting device is troublesome to operate and requires larger manpower, thereby increasing the labor intensity of operators. Therefore, the workpiece auxiliary supporting device effectively solves the problems that the existing workpiece auxiliary supporting device is troublesome to operate and labor intensity of operators is high.
