Each first clamping assembly 6 is provided with two limit rods 607 and two springs 609.

[0046] A plate punching method for furniture production comprises the following specific steps:

[0047] S1. First, place the furniture board that needs to be punched on the placement plate 4, then start the second motor 8, control the threaded rod 9 to rotate in the opposite direction, so that the threaded plate 11 moves down to the lowest point, and then adjust the position of the clamping block 610 through the second electric cylinder 606, so that the clamping block 610 clamps the furniture board, and at the same time use the same method to adjust the second clamping assembly 7. After the adjustment is completed, start the second motor 8 again, control the threaded rod 9 to rotate forward, so that the threaded plate 11 moves up to the highest point. At this time, the first connecting rod 13, the second connecting rod 605 and the second electric cylinder 606 are all in a horizontal state. Then, move the extrusion plate 612 to the top of the clamping block 610, and press the clamping block 610 into the interior of the placement plate 4. Finally, screw the positioning pin 615 into the interior of the positioning hole 614, and fix the extrusion plate 612.

[0048] S2. After the adjustment of the first clamping assembly 6 and the second clamping assembly 7 is completed, the furniture board is opened. First, the board is placed on the placement plate 4. After the placement is completed, the second motor 8 rotates in the opposite direction to move the threaded plate 11 downward, thereby controlling the first clamping assembly 6 and the second clamping assembly 7 to clamp and fix the board. Then, the drill bit 20 is moved to the position where a hole is required to be drilled through the transverse adjustment assembly 15 and the longitudinal adjustment assembly 16. The third motor 19 is started and drives the drill bit 20 to rotate. At the same time, the first electric cylinder 18 controls the drill bit 20 to move downward to drill a hole.

[0049] The working principle of the first clamping assembly 6 is as follows: when the second motor 8 controls the threaded plate 11 to move downward, the slide plate 602 moves toward the plate under the action of the first connecting rod 13, the second connecting rod 605 and the second electric cylinder 606. At the same time, when the clamping block 610 moves away from the bottom of the extrusion plate 612, the clamping block 610 pops out from the inside of the placement plate 4 under the action of the spring 609 and clamps the plate. When the second motor 8 controls the threaded plate 11 to move upward, the slide plate 602 moves in the direction away from the plate under the action of the first connecting rod 13, the second connecting rod 605 and the second electric cylinder 606, and the clamping block 610 loosens the plate. When the clamping block 610 contacts the extrusion plate 612, the extruded plate 612 is pressed into the interior of the placement plate 4 to accommodate the clamping block 610. The second electric cylinders 606 on the two first clamping assemblies 6 work simultaneously during adjustment.

[0050] The working principle of the second clamping assembly 7 is the same as that of the first clamping assembly 6. The first clamping assembly 6 mainly clamps the plate left and right, while the second clamping assembly 7 mainly clamps the plate front and back.

[0051] S3. After the drilling is completed, the first electric cylinder 18 controls the drill bit 20 to move up to the initial position. At the same time, the third motor 19 stops working, and the second motor 8 rotates forward to move the threaded plate 11 up, thereby controlling the first clamping assembly 6 and the second clamping assembly 7 to loosen the plate.

[0052] While embodiments of the present invention have been shown and described, it will be appreciated 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 invention, and that the scope of the invention is defined by the appended claims and their equivalents.
