[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0019] Example

[0020] See also Figure 1-4 , this embodiment provides a plate cutting and positioning structure, including a base 1 of a cutting device.

[0021] Specifically, a bracket 3 is fixedly connected to the upper end of the base 1 , and two brackets 3 are provided. The two brackets 3 are respectively located on both sides of the upper end of the base 1 , and the two brackets 3 are arranged opposite to each other. Two sliding rods 31 are fixedly connected between the two brackets 3 .

[0022] like Figure 1 and Figure 3 As shown, a sliding hole is opened at the upper end of the cutting knife 4, and the sliding rod 31 slides through the sliding hole. The cutting knife 4 is slidably installed on the sliding rod 31 through the sliding hole. The cutting knife 4 is set as an electric cutting device, and a circular saw is used to cut the plate.

[0023] like Figure 1 As shown, the upper end of the base 1 is fixedly connected to a placement plate 2, and the upper end of the placement plate 2 is used to place the plate. A cutting groove is opened at the upper end of the placement plate 2. When the cutting knife 4 moves to the upper end of the placement plate 2, the circular saw of the cutting knife 4 is located below the cutting groove. The cutting knife 4 is manually moved to cut the plate placed on the placement plate 2 by the circular saw.

[0024] like Figure 1 and Figure 2 As shown, a screw rod 32 is rotatably installed between the two brackets 3, and a motor is fixedly installed on one side of one bracket 3. The output shaft of the motor passes through the bracket 3 and is fixedly connected to one end of the screw rod 32. The screw rod 32 can be driven to rotate by the motor. A threaded groove is provided at the upper end of the cutting knife 4. The upper end of the cutting knife 4 is threadedly connected to the screw rod 32 through the threaded groove. The movement of the cutting knife 4 can be controlled by rotating the screw rod 32, and the sliding rod 31 is used to prevent the cutting knife 4 from rotating as the screw rod 32 rotates.

[0025] Existing cutting devices cannot locate the position to be cut, so Figure 1 and Figure 3 As shown, a positioning mechanism 5 is provided on the sliding rod 31 .

[0026] Specifically, the positioning mechanism 5 includes a sliding block 51 and a positioning rod 52, wherein the sliding block 51 is also provided with a sliding hole, and the sliding rod 31 slides through the sliding hole of the sliding block 51, and the sliding block 51 is slidably installed on the sliding rod 31 through the sliding hole. The sliding block 51 is also provided with a through hole, and the screw rod 32 slides through the through hole of the sliding block 51. A connecting rod 6 is fixedly connected between the sliding block 51 and the cutting knife 4. During the movement of the cutting knife 4, the sliding block 51 is driven to move synchronously by the connecting rod 6.

[0027] The lower end of the sliding block 51 is fixedly connected to a hinge support, and the upper end of the positioning rod 52 is rotatably connected to the hinge support, that is, the positioning rod 52 is rotatably connected to the lower end of the sliding block 51.

[0028] When placing a plate on the placement plate 2, the side of the plate will exert a reverse force on one side of the positioning rod 52, thereby driving the positioning rod 52 to rotate. When the plate continues to move toward the cutting knife 4, the lower end of the positioning rod 52 is located at the upper end of the plate due to its own weight. Since the sliding rod 31, the cutting knife 4, the positioning rod 52, and the sliding block 51 are located in the same vertical plane, when the cutting knife 4 moves toward the plate for cutting after startup, the contact surface between the positioning rod 52 and the plate is the position where the cutting knife 4 will move to cut, thereby positioning the cutting position of the cutting knife 4.

[0029] like Figure 4 As shown, the upper end of the outer wall of the positioning rod 52 is fixedly connected to the edge block 521, and an elastic member 53 is fixedly connected between the edge block 521 and the sliding block 51. The elastic member 53 is set as a contraction spring, and the elastic member 53 applies a contraction force toward the sliding block 51 to the edge block 521, and then uses the hinge support at the lower end of the sliding block 51 as a fulcrum to drive the lower end of the positioning rod 52 to fit tightly on the plate through the lever principle.

[0030] When the plate needs to be removed, the positioning rod 52 will exert downward pressure on the plate, making it difficult to remove the plate. Figure 4 As shown, a handle 54 is rotatably installed on the hinge support at the lower end of the sliding block 51. Both ends of the handle 54 pass through the hinge support and are fixedly connected to the upper ends of the positioning rod 52 and the rotating connection between the hinge support. By rotating the handle 54, the hinge support at the lower end of the sliding block 51 can be used as a fulcrum to drive the positioning rod 52 to rotate through the lever principle.

[0031] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
