[0018] The utility model is further described below in conjunction with the accompanying drawings.

[0019] according to Figure 1-4 As shown: the utility model provides a milling cutter assembly for a horizontal milling machine: it includes a milling machine body 1 and a milling cutter 4, a rotating shaft 3 is rotatably arranged on the milling machine body 1, and a power device 2 for providing power for the rotation of the rotating shaft 3 is arranged on the milling machine body 1; two milling cutters 4 are arranged, and mounting holes 6 are opened in the two milling cutters 4; a guide groove 5 is opened on the rotating shaft 3, and the two milling cutters 4 are slidably sleeved on the rotating shaft 3, and the two milling cutters 4 slide along the direction of the guide groove 5; a positioning hole 7 is opened on the inner wall of the mounting hole 6, and a positioning rod 8 inserted into the positioning hole 7 is arranged in the guide groove 5; the positioning rod 8 is slidably arranged in the guide groove 5.

[0020] The positioning rod 8 is provided to facilitate installation of the milling cutter 4, and the sliding of the positioning rod 8 can drive the milling cutter 4 to slide on the rotating shaft 3, thereby solving the problem of the prior art that it is inconvenient to adjust the relative positions of two milling cutters 4 on the same rotating shaft 3.

[0021] A groove 12 communicating with the guide groove 5 is formed in the rotating shaft 3 , and a bidirectional screw 10 is rotatably arranged in the groove 12 ; two movable plates 11 arranged opposite to each other are threadedly connected to the bidirectional screw 10 .

[0022] The bidirectional screw 10 can drive the two milling cutters 4 to move toward or away from each other through the two moving plates 11 , which greatly increases the efficiency of adjusting the relative positions of the two milling cutters 4 .

[0023] An electric telescopic rod 9 is fixedly arranged on the moving plate 11, and the end of the electric telescopic rod 9 is fixedly connected to the positioning rod 8. The mounting hole 6 of the milling cutter 4 is provided with two corresponding positioning holes 7, and each moving plate 11 is provided with two electric telescopic rods 9, and the two electric telescopic rods 9 correspond to the two positioning holes 7 respectively. The two electric telescopic rods 9 have exactly the same structure, and the two electric telescopic rods 9 are controlled by the same control circuit.
