[0019] Please refer to Figures 1-4 , the present invention provides a technical solution: an automatic cutting device for metal cabinet doors, including an operating table 1. A cabinet door is placed on the upper end surface of the operating table 1, and a groove is opened on the operating table 1 below the cabinet door. An electric slide rail 2 is embedded in the rear of the operating table 1, and a slider 3 is inserted through the upper part of the electric slide rail 2. A first fixing frame 4 is provided above the slider 3, and a first servo motor 5 is provided inside the first fixing frame 4. One end of the output shaft of the first servo motor 5 is connected to a first screw rod 6 through a coupling. A first sliding rod 7 is correspondingly provided on one side of the first screw rod 6, and a first movable block 8 is inserted through the first screw rod 6 and the first sliding rod 7. An electric push rod 9 is provided on the first movable block 8, and a telescopic arm 10 is provided on the electric push rod 9.

[0020] Further, under the action of the first servo motor 5, the electric push rod 9 forms a limiting sliding structure with the first fixing frame 4 through the first screw rod 6, the first sliding rod 7, and the first movable block 8, so as to drive the laser cutting head 15 and the grinding block 16 assembly to perform limiting lifting through the first servo motor 5. And under the action of the electric push rod 9, the motor box forms a horizontal pushing structure with the first fixing frame 4 through the telescopic arm 10, so as to drive the laser cutting head 15 and the grinding block 16 assembly to move through the electric push rod 9, thereby ensuring that the laser cutting head 15 cuts on the metal cabinet door.

[0021] The other end of the telescopic arm 10 is provided with a motor box, and a second servo motor 11 is provided inside the motor box. The second servo motor 11 is provided with an output shaft, and a turntable 12 is provided at the other end of the output shaft. A fixing block 13 is provided on the turntable 12, and an operating head 14 is provided on one side of the fixing block 13. A laser cutting head 15 is provided on the operating head 14. A connecting plate is provided on the other side of the fixing block 13, and a grinding block 16 is provided on the connecting plate.

[0022] Further, the grinding block 16 and the laser cutting head 15 respectively form a rotating structure with the motor box through the turntable 12 and the fixing block 13 under the action of the second servo motor 11, so as to ensure that the edge of the metal cabinet door can be polished in time after cutting by rotating and replacing the laser cutting head 15 and the grinding block 16, thereby ensuring the flatness of the cut of the metal cabinet door.

[0023] On the upper end surface of the operation table 1, second fixing frames 17 are respectively provided on both sides. A third servo motor 18 is provided inside the second fixing frame 17. One end of the output shaft of the third servo motor 18 is connected to a second screw rod 19 through a coupling. A first synchronous pulley is sleeved on the second screw rod 19. A second synchronous pulley is correspondingly provided on one side of the first synchronous pulley. A synchronous belt is sleeved on the outer walls of the first synchronous pulley and the second synchronous pulley. The second synchronous pulley is also inserted with the second screw rod 19 inside. A second sliding rod 20 is correspondingly provided on the outer side of the second screw rod 19. A second movable block 21 is inserted on the second screw rod 19 and the second sliding rod 20.

[0024] Further, the second screw rod 19 forms a linkage structure through the first synchronous pulley, the second synchronous pulley and the synchronous belt under the action of the third servo motor 18. The second movable block 21 forms a limiting sliding structure through the second screw rod 19 and the second sliding rod 20 under the action of the third servo motor 18. Thus, under the action of the third servo motor 18, the limiting block 25 assembly is driven to perform limiting lifting, and then the edge of the cut is shielded and protected by the limiting block 25.

[0025] A hollow rod 22 is provided on the second movable block 21. The hollow rod 22 is inserted through the upper connecting block 23. The connecting block 23 is provided on the limiting block 25.

[0026] Further, the hollow rod 22 forms a spiral locking structure with the limiting block 25 through the bolt and the connecting block 23. The inside of the limiting block 25 forms a communicating structure with the air conditioner through the air inlet pipe 24. Thus, the limiting block 25 is convenient to replace through the bolt. At the same time, the limiting block 25 is ensured to be in a low-temperature state through the air inlet pipe, and the edge of the cut is further protected.

[0027] Working principle: When using the automatic cutting device for metal cabinet doors, first place the metal cabinet door to be processed on the operating table 1. At the same time, install the grinding block 16 and the limit block 25 with appropriate sizes according to the size of the cut to be made. Subsequently, the third servo motor 18 can be started. The output shaft of the third servo motor 18 drives the second screw rod 19 to rotate through a coupling, so as to drive the second movable block 21 to perform limited lifting through the second slide rod 20, so as to drive the limit block 25 to protect the cutting area. At the same time, ensure that the inside of the limit block 25 is at a low temperature through the air inlet pipe 24, and then avoid the high temperature of the laser cutting head 15 from affecting the edge of the cut through the limit block 25; after the limit block 25 is placed, the electric push rod 9 can be started. The electric push rod 9 drives the laser cutting head 15 to move to the cutting area of the metal cabinet door through the telescopic arm 10. Then, the electric slide rail 2 and the first servo motor 5 can be started simultaneously, so as to drive the laser cutting head 15 to move through the slider 3 and the first movable block 8, and then cut the metal cabinet door through the laser cutting head 15; after the metal cabinet door is cut, the laser cutting head 15 assembly can be driven to rise by the first servo motor 5. At the same time, the second servo motor 11 can be started, so as to drive the laser cutting head 15 and the grinding block 16 to rotate and replace through the turntable 12, so as to polish the edge of the cut through the grinding block 16, further ensuring the flatness of the cut of the metal cabinet door. This is the usage process of the automatic cutting device for metal cabinet doors.
