Through this design, the problem of reduced cutting accuracy caused by the movement or vibration of the metal fixing plate during laser cutting can be effectively avoided;

[0045] At the same time, when the two push-pull rods 329 move inward, the two sets of rotating rod connecting rods 3214 drive the two sets of rotating rods 3215 to rotate, and the two sets of rotating rods 3215 rotate to push the laser cutting machine connecting plate 3216 to move downward and drive the laser cutting machine 3218 at the bottom to move downward close to the surface of the metal fixing plate fixed by the two sets of thickness sensing clamps 3213.

[0047] When the metal fixing plate is transmitted on the conveyor belt of the laser cutting device 1, when the metal fixing plate moves to the inner side of the two hub plates 48, the two hydraulic push rods 43 are started. After the two hydraulic push rods 43 are started, they push the L-shaped rotating rod push block 46 to drive the L-shaped rotating rod 45 to rotate. The two L-shaped rotating rods 45 rotate around the L-shaped rotating rod hinge block 44, and then push the abutment plate 47 to drive the hub plate 48 to move inward. At this time, the metal fixing plate is clamped on the inner side of the two hub plates 48. When the conveyor belt of the laser cutting device 1 continues to transport, the metal fixing plate can move by rotating the multiple hubs 49 fixed to the inner wall of the hub plate 48, thereby realizing stable transportation and precise positioning of the metal fixing plate.

[0048] In addition, the present invention also relates to a cutting method of a hardware laser cutting device for furniture processing, comprising the following steps:

[0049] Step 1: placing the metal fixing plate on the conveyor belt, and starting the conveyor belt to move the metal fixing plate to the inner wall of the laser cutting device 1;

[0050] Step 2: Control the bottom of the laser cutting device 1 to fall to a suitable position through the main control frame 2 to ensure that the metal fixing plate can be aligned with the bottom of the control mechanism 3;

[0051] Step 3: With the assistance of the positioning mechanism 4, the metal fixing plate rotates through the hub 49 on the hub plate 48 to achieve stable transportation and precise positioning.

[0052] Step 4: Position the metal fixing plate through the control mechanism 3 and adjust its position so that it is completely separated from the positioning mechanism 4;

[0053] Step 5: Start the bidirectional hydraulic push rod 324 in the control mechanism 3, so that the push-pull block 3210 drives the push-pull rod 329 and the push-pull cross bar 326 to move inward, thereby clamping the metal fixing plate, and sensing the thickness of the metal fixing plate through the thickness sensing clamp 3213;

[0054] Step 6: The laser cutting machine 3218 performs precise laser cutting on the metal fixing plate under the control of the control mechanism 3 to ensure that the cutting path and depth meet the design requirements;

[0055] Step 7: After the cutting is completed, the bidirectional hydraulic push rod 324 works in the reverse direction to move the laser cutting machine 3218 and the thickness sensing clamping plate 3213 back to the initial position to prepare for the next cutting operation.

[0056] Working principle of the present invention: When it is necessary to perform laser cutting on the metal fixed plate, first start the two-way hydraulic push rod 324 at the bottom of the two-way push rod connecting plate 321. After the two-way hydraulic push rod 324 is started, it pulls the two push-pull blocks 3210 inward to move. The movement of the two push-pull blocks 3210 drives the push-pull rod 329 inward to pull the two push-pull cross bars 326 to slide inward on the inner wall of the C-shaped slide frame 325. When the two push-pull cross bars 326 slide inward, the two sets of hinge blocks 327 pull the two sets of rotating rods 328 in opposite directions to rotate. The two sets of rotating rods 328 pull the L-shaped expansion rod 3212 to slide inward on the inner sides of the connecting block 313 and the connecting block 316, thereby driving the two sets of thickness sensing clamps 3213 to move inward to clamp and fix the metal fixing plate on the conveyor belt, and sense the thickness of the metal fixing plate through the inner sides of the two sets of thickness sensing clamps 3213. This design can effectively avoid the problem of reduced cutting accuracy caused by the movement or vibration of the metal fixing plate during the laser cutting process. At the same time, when the two push-pull rods 32 While moving inward, the two sets of rotating rod connecting rods 3214 further drive the two sets of rotating rods 3215 to rotate, and the two sets of rotating rods 3215 rotate to push the laser cutting machine connecting plate 3216 to move downward and drive the laser cutting machine 3218 at its bottom to move downward close to the surface of the metal fixing plate fixed by the two sets of thickness sensing clamps 3213. At this time, the metal fixing plate can be laser cut by the laser cutting machine 3218. After the laser head of the laser cutting machine 3218 is aligned with the predetermined cutting position of the metal fixing plate, the laser cutting machine 3218 starts to work and emits a laser beam to accurately cut the metal fixing plate. During the cutting process, the movement of the laser cutting machine 3218 is accurately controlled by the control mechanism 3 to ensure that the cutting path and depth meet the design requirements. After the cutting is completed, the two-way hydraulic push rod 324 works in the reverse direction to move the laser cutting machine 3218 and the thickness sensing clamp 3213 back to the initial position to prepare for the next cutting operation. The entire cutting process has a high degree of automation and is easy to operate, which greatly improves the production efficiency and cutting accuracy of furniture processing hardware.

[0057] When the metal fixing plate is transmitted on the conveyor belt of the laser cutting device 1, when the metal fixing plate moves to the inner side of the two hub plates 48, the two hydraulic push rods 43 are started. After the two hydraulic push rods 43 are started, they push the L-shaped rotating rod push block 46 to drive the L-shaped rotating rod 45 to rotate. The two L-shaped rotating rods 45 rotate around the L-shaped rotating rod hinge block 44, and then push the abutment plate 47 to drive the hub plate 48 to move inward. At this time, the metal fixing plate is clamped on the inner side of the two hub plates 48. When the conveyor belt of the laser cutting device 1 continues to transport, the metal fixing plate can move by rotating the multiple hubs 49 fixed to the inner wall of the hub plate 48, thereby realizing stable transportation and precise positioning of the metal fixing plate.
