[0015] Preferably, the scraper block is in an arc shape.

[0016] Preferably, the method for using the automatic punching machine for wooden door processing comprises the following steps:

[0017] S1: When the device punches holes on the side of the wooden door, the wooden door to be punched is transported to the rear side of the fixed bracket by the conveying clamping table, and then the bidirectional motor and the cylinder are driven to move backward synchronously by starting the first cylinder. At this time, the bidirectional motor drives the universal joint to rotate counterclockwise, causing the connecting disk on one end of the universal joint to rotate while moving circumferentially along the inner wall of the limit sleeve, so that the pentagonal prism follows the connecting disk to rotate eccentrically on the inner wall of the hollow sleeve, causing the cylinder on the pentagonal prism to rotate, cooperate with the scraper block to punch a hexagonal hole on the side of the wooden door, and the scraper on one end of the cylinder cuts the side of the wooden door;

[0018] S2: While the bidirectional motor drives the universal joint to rotate counterclockwise and move backward, the power motor drives the transmission gear to rotate and drives the chain to rotate, and the cutter on the chain slowly contacts the side of the wooden door and gradually penetrates into the inside thereof to punch a square hole on the side of the wooden door. When the cutter and the cylinder move to a specified depth, the power motor stops rotating, and the bidirectional motor drives the universal joint to rotate clockwise, causing the scraper to contact the inner wall of the square groove of the wooden door. The resistance between the inner walls of the square groove of the scraper causes the rotating rod to passively deflect counterclockwise. At this time, the protrusion on the side of the rotating rod rotates counterclockwise at a specified angle and contacts the other side of the limit plate, thereby preventing the rotating rod from deflecting too much.

[0019] S3: When the rotating rod rotates, it drives the pushing block on its side to squeeze the folding rod to fold, causing the sliding cutting knife on one end of the folding rod to slide on the inner wall of the slot and extend outward and rotate, and then the rotating rod rotates to drive the extended sliding cutting knife to rotate, and after the wood block remaining on the inner side of the cutting knife after punching is cut off, the bidirectional motor rotates counterclockwise, and under the action of the reset spring, the folding rod is pulled to shrink and reset, and finally the worm is driven to rotate by the micro motor, causing the worm wheel to rotate and push the nut on its outer side to move forward, pulling the folding connecting frame to fold and shorten, increasing the squeezing force of the cutting knife on the residual wood chips in the square hole, and then the cutting knife is driven forward by the contraction of the first cylinder, and then the wood block produced by the punching is taken out of the square hole.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] In the present invention, a power motor drives a transmission gear to rotate, which drives a chain to rotate. A cutter on the chain slowly contacts the side of a wooden door and gradually penetrates into the interior thereof, so as to punch square holes on the side of the wooden door. The device is simple and convenient for punching holes, and has high precision in punching square holes.

[0022] In the present invention, when the chain drives the cutter to rotate and contact the side of the wooden door and gradually penetrate into the interior thereof to punch a square hole on the side of the wooden door, the first cylinder drives the bidirectional motor and the cylinder to move backward synchronously. At this time, the bidirectional motor drives the universal joint to rotate counterclockwise, causing the connecting disk on one end of the universal joint to rotate while moving circumferentially along the inner wall of the limit sleeve, so that the pentagonal prism follows the connecting disk to rotate eccentrically on the inner wall of the hollow sleeve, causing the cylinder on the pentagonal prism to rotate, cooperate with the scraper block to punch a hexagonal hole on the side of the wooden door, and the scraper on one end of the cylinder cuts the side of the wooden door, thereby increasing the smoothness of the backward movement of the cylinder.

[0023] In the present invention, the universal joint is driven by a bidirectional motor to rotate clockwise, so that the scraper plate contacts the inner wall of the square groove of the wooden door, and the resistance between the inner walls of the scraper plate square groove causes the rotating rod to passively deflect counterclockwise, driving the pushing block on its side to squeeze the folding rod to fold, causing the sliding cutting knife on one end of the folding rod to slide on the inner wall of the slot and extend outward and rotate, and then the extended sliding cutting knife is driven to rotate by the rotation of the rotating rod, and after the wood block remaining on the inner side of the cutting knife after punching is cut off, the worm is driven to rotate by the micro motor, causing the worm wheel to rotate and push the nut on the outer side thereof to move forward, pulling the folding connecting frame to fold and shorten, thereby increasing the squeezing force of the cutting knife on the wood chips remaining in the square hole, and then the cutting knife is driven to move forward by the contraction of the first cylinder, and then the wood block produced by the punching is taken out of the square hole.

At this time, the protrusion (67) on the side of the rotating rod (64) rotates counterclockwise by a specified angle and contacts the other side of the limit plate (68), thereby preventing the rotating rod (64) from deflecting too much. S3: When the rotating rod (64) rotates, the push block (69) on the side thereof squeezes the folding rod (610) to fold, causing the sliding cutting knife (611) on one end of the folding rod (610) to slide on the inner wall of the slot (613) and extend outward and rotate. Then, the rotating rod (64) rotates to drive the extended sliding cutting knife (611) to rotate, and the wood block remaining on the inner side of the cutting knife (513) after punching is cut off. Then, the bidirectional motor (43) rotates counterclockwise. The folding rod (610) is pulled to retract and reset under the action of the reset spring (614), and finally the micro motor (54) drives the worm (53) to rotate, causing the worm wheel (52) to rotate and push the nut (55) on the outside thereof to move forward, thereby pulling the folding connecting frame (56) to fold and shorten, thereby increasing the squeezing force of the cutter (513) on the remaining wood chips in the square hole, and then the cutter (513) is driven to move forward by the contraction of the first cylinder (41), thereby removing the wood block produced by the punching from the square hole.
