Suspension type center tail bracket

The invention discloses a suspension type center tail bracket which comprises a center, a tail bracket, a trapezoidal guide rail, a ball screw pair, a servo motor, a transverse beam and an oblique support. The center is mounted on the tail bracket, the tail bracket is slidably mounted on the trapezoidal guide rail, a nut of the ball screw pair is fixed onto the tail bracket, a lead screw of the ball screw pair is connected with the servo motor, and the servo motor can drive the tail bracket via the ball screw pair to horizontally linearly slide on the trapezoidal guide rail; the oblique support is fixed onto the transverse beam and is positioned on the lower side of the transverse beam, the servo motor is mounted on the oblique support, the tail bracket is reversely suspended on the trapezoidal guide rail, and the trapezoidal guide rail is fixed onto the transverse beam. The suspension type center tail bracket has the advantages that the tail bracket is unconventionally mounted on the transverse beam and is suspended, and the tail bracket and tool rests are vertically arranged, and accordingly conditions can be created for adjusting lower horizontally mounted hobbing heads in large ranges; the tool rests and the tail bracket are vertically arranged, accordingly, occupied spaces of machine tools can be saved, and the suspension type center tail bracket is favorable for simplifying the structures of the machine tools.
