Engage with the rack 10 on the knife adding seat 17, and the rack knife box 12 is horizontally installed on the knife adding seat 17 to mesh with the gear 11; the connecting mechanism connects the upper knife adding control mechanism and the lower knife adding actuator, and the connecting mechanism is connected by the transmission Rod 8, bearing 9, plane bearing 6 are made up, transmission rod 8 is installed on the bearing 9 in the center of main shaft 14, and transmission rod 8 bottom is connected with rack 10 by screw 18 through spherical washer 16, and transmission rod 8 top is connected with plane bearing 6 and Screw nut seat 5 is connected.

In the present invention, after the numerical control system of the numerical control vertical boring machine issues an instruction, the servo motor 1 rotates, drives the screw rod 4 to rotate through the shaft coupling 2, and converts the rotational motion of the screw rod 4 into the screw nut seat 5 along the The guide rail of the support seat 7 moves up and down, driving the transmission rod 8 to transmit the up and down motion to the rack 10, and the gear 11 meshing with the rack 10 and the rack knife box 12 converts the up and down motion of the rack 10 into the rack knife box 12 The horizontal movement of the tool drives the expansion and contraction of the tool 19, and realizes the functions of automatic tool addition and tool withdrawal. By controlling the speed and revolutions of the servo motor 1, the speed and distance of tool movement can be realized respectively, and then the rotation of the main shaft 4 and the up and down movement of the carriage can be used to process holes of different diameters, taper holes, inner hole slotting and end faces. . The machining efficiency of machining holes with different diameters is improved, and the functions of machining taper holes, grooves and end faces in the holes are realized.
