[0021] Please refer to the attached Figure 1-Figure 5 Those skilled in the art should understand that these embodiments are only used to explain the technical principles of the present invention and are not intended to limit the protection scope of the present invention.

[0022] The utility model proposes a plate fixing mechanism for a CNC slotting machine. Before use, each pair of clamping plates 4 and the corresponding limiting plates 5 are at the farthest relative distance. When using the device, a group of plates are placed between the corresponding group of clamping plates 4 and the limiting plates 5. Figure 1As shown, the top end of a group of plates is placed on one side of the top plate 9, and the motor 6 is started. The motor 6 drives the corresponding pulley 13 to rotate, and one pulley 13 drives the other two pulleys 13 to rotate through the belt 14, and a group of pulleys 13 drives the corresponding lead screw 12 to rotate, and a group of lead screws 12 rotate and drive the corresponding sleeve 11 to slide in the direction close to the motor 6, and a group of sleeves 11 drives the corresponding splints 4 to slide along the corresponding connecting plates 3 to the direction close to the motor 6, and a group of splints 4 drives the corresponding guide rods 8 to slide along the corresponding circular blocks 7 to the direction close to the motor 6, and a group of guide rods 8 drive the corresponding remaining splints 4 to slide along the corresponding connecting plates 3 to the direction close to the motor 6, and each splint 4 slides in the direction close to the corresponding limit plate 5. When a group of splints 4 and the corresponding limit plate 5 are opposite to each other on one side of the corresponding plate, the motor 6 is turned off first, and a group of plates are pushed again to make the top end of a group of plates fit closely to one end of the top plate 9, so that a group of plates are in a flush state to avoid When the subsequent slotting positions are not uniform, after adjusting the position of the plate, the motor 6 is started again. When a group of clamping plates 4 and the corresponding limit plates 5 are tightly attached to one side of the plate, the motor 6 is turned off, and the fixation of a group of plates is completed. The tool holder 15 is started to slot a group of plates. After the slotting is completed, the motor 6 is started again. The motor 6 reverses and drives the device to return to the initial state, and the processed plate is removed. The device uses a group of clamping plates 4 to cooperate with the corresponding limit plates 5 to limit and fix the plates, which is convenient for limiting and fixing plates of different widths, replacing the traditional combination of limit columns and fixed rods to limit, increasing the contact area between the plate and the plate, reducing the disadvantage of only a small section of the plate being subjected to force, and cooperating with the rubber layer to better protect the side of the plate, avoiding the situation where the side of the plate is dented, and the fixing effect is better. The device only needs to use one electrical component, the motor 6, to achieve the purpose of simultaneously moving the limit, replacing the traditional multiple cylinders, reducing the use of electrical components, and reducing the cost.
