[0029] In this embodiment, the reciprocating processing mechanism includes a guide rail frame 7 fixedly connected to the top outer wall of the T-shaped adjustment seat 5, a lead screw 8 rotatably mounted on the guide rail frame 7, a servo motor 9 fixedly mounted on the top outer wall of the guide rail frame 7, a reciprocating slide 10 threadedly connected to the lead screw 8 and slidably connected to the guide rail frame 7, and an electric gear hobbing cutter 11 mounted on the side wall of the reciprocating slide 10;

[0030] Furthermore, the output shaft of the servo motor 9 passes through the top of the guide rail frame 7 and is coaxially fixedly connected to the top of the lead screw 8 through a coupling;

[0031] In the specific implementation of this embodiment: first, the threaded rod 4 is controlled to rotate by the hand wheel 6, and then under the limit of the slide groove 3, the T-shaped adjustment seat 5 threadedly connected to the threaded rod 4 will drive the electric gear hobbing cutter 11 on the guide rail frame 7 to move forward, so that the electric gear hobbing cutter 11 can effectively contact the engine brackets of different thicknesses and specifications, so as to adapt to the gear hobbing processing of the engine brackets of different thicknesses and specifications;
