Specifically, during implementation, a guiding track that is fixedly installed on one side of the frame 1 and slidably cooperates with one side of the machine base 3 can be provided.

[0024] In this technical solution, a support 4 is fixedly arranged on the top of the machine base 3. A positioning plate 5 is rotatably connected to the support 4, and the rotation axis of the two is parallel to the sliding direction of the machine base 3. Preferably, in specific implementation, the support 4 is of a trough-shaped structure, and positioning holes 41 are formed on both sides thereof. Positioning shafts 51 which are rotatably connected to the positioning holes 41 through bearings are welded to both ends of the positioning plate 5. Thus, when the positioning plate 5 rotates, the angle between it and the horizontal plane changes. During use, scales can be marked on the side wall of the support 4, and the angle of inclination of the positioning plate 5 relative to the horizontal plane can be obtained through the scales.

[0025] A control motor 6 is fixedly arranged on the back surface of the positioning plate 5. The output shaft of the control motor 6 is fixedly connected with a milling cutter 8 located on the front side of the positioning plate 5 through a connecting jacket 7. The milling cutter 8 is of a cylindrical thread structure, and the milling cutter 8 is perpendicular to the positioning plate 5. The control motor 6 provides driving force for the rotation of the milling cutter 8. When the positioning plate 5 rotates, the distance between the axis of the milling cutter 8 and the horizontal plane changes. When it is necessary to machine a 45-degree bevel angle on a plate, rotate the positioning plate 5 to make the axis of the milling cutter 8 form a 45-degree angle with the horizontal plane. When it is necessary to machine a 30-degree bevel angle, rotate the positioning plate 5 to change the angle between the milling cutter 8 and the horizontal plane. In this way, bevel angles of various specifications can be machined quickly. Compared with the prior art, there is no need to replace different tools.

[0026] A control assembly 9 for controlling the rotation of the positioning plate 5 is arranged on one side of the support 4. The function of the control assembly 9 is to quickly adjust the angle between the milling cutter 8 and the horizontal plane.

The worm 92 is rotatably connected to one side outside the support 4 and meshes with the worm gear 91. One end of the worm 92 is fixedly connected with a knob disk 921. During use, manually rotate the knob disk 921 to control the rotation of the worm 92, and then the worm gear 91 can rotate to realize the adjustment of the inclination angle of the positioning plate 5.

[0028] In this embodiment, a gantry 21 close to one side of the frame 1 is fixedly connected to the upper end surface of the placement platform 2. The top inside the gantry 21 is connected to a pressing plate 102 through an electric telescopic rod 101. The electric telescopic rod 101 controls the up and down movement of the pressing plate 102. The function of the pressing plate 102 is to press the plate placed on the placement platform. On the upper end surface of the placement platform 2, there are parallel side plates 103 close to both sides. The function of the side plates 103 is to correct the position of the plate, so that the side of the plate to be cut is parallel to the sliding direction of the machine base 3. A row of slots 22 that are inserted and matched with the bottom of the side plates 103 are provided on the upper end surface of the placement platform 2. The setting of multiple slots 22 facilitates changing the position of the side plates 103 on the placement platform 2, making it suitable for the reliance of plates with different widths. For example, for a plate with a smaller width, after adjusting the position of one of the side plates 103, the stroke when the plate and the milling cutter 8 are aligned can be shortened.

[0029] In this embodiment, a reciprocating lead screw 104 is rotatably connected to one side of the frame 1. The reciprocating lead screw 104 is threadedly connected through the machine base 3. Specifically, a nut sleeve that is threadedly engaged with the reciprocating lead screw 104 can be provided through the machine base 3 during implementation. A driving motor 105 is fixedly connected to one side of the machine base 3. The output shaft of the driving motor 105 is fixedly connected to one end of the reciprocating lead screw 104. The driving motor 105 provides driving force for the rotation of the reciprocating lead screw 104. When the reciprocating lead screw 104 rotates, it can drive the machine base 3 to move back and forth.

[0030] In this embodiment, a calibration plate 106 located on one side of the milling cutter 8 is provided through the upper end of the positioning plate 5. The calibration plate 106 is of a straight plate structure. The calibration plate 106 is parallel to the milling cutter 8 and is slidably engaged with the positioning plate 5. Specifically, a guide sleeve can be welded through the positioning plate 5 during implementation, and a rubber sleeve that is damping slidably engaged with the calibration plate 106 is nested inside the guide sleeve. The function of the calibration plate 106 is to assist in aligning the milling cutter 8 and the plate.

[0031] Working principle: When in use, that is, when cutting a certain bevel angle, adjust the inclination angle of the milling cutter 8, then place the plate on the placement platform 2, and at the same time rely one side of the plate on one of the side plates 103. Control the movement of the machine base 3 so that one side of the calibration plate 106 abuts against the plate, thereby facilitating the determination of the cutting and processing position of the plate. After the position is determined, control the pressing plate 102 to press the plate, and then press the calibration plate 106 to move the calibration plate 106 away from the position between the plate and the milling cutter 8. Then start the control motor 6, the control motor 6 drives the milling cutter 8 to rotate at a high speed, start the driving motor 105, the reciprocating lead screw 104 drives the machine base 3 to move, and when the milling cutter 8 contacts the plate, the bevel angle can be cut.
