[0015] The wood board drilling device has the following advantages:

[0016] 1. The solid wood board drilling device of the present invention is equipped with multiple board placement platforms. During the solid wood board drilling process, while drilling is being performed on the board on the board drilling platform below the lifting drill, the boards on the board drilling platforms in other positions can be installed, adjusted, and removed. In the board drilling device of this application, drilling, loading, and unloading are carried out simultaneously, saving idle time and effectively improving the efficiency of solid wood board drilling and the speed of board processing during mass production.

[0017] 2. The wooden board drilling frame of the present invention is equipped with a solid wood board positioning mechanism. The solid wood board positioning mechanism can clamp the wooden board from four directions, which further improves the positioning stability of the wooden board. At the same time, during the clamping process, the four limiting locking plates move from the outside to the inside, which can push the wooden board that was originally slightly off-center to the center position of the wooden board drilling frame. It has a certain correction effect, improves the positioning accuracy of the wooden board, and eliminates the need for overly precise control of the wooden board position during the feeding process, thus reducing the time consumed for adjusting the position of the wooden board during the feeding process.

[0018] 3. The wooden board drilling frame of this invention has a synchronous push rod inside. Under normal conditions, the push rod and push spring apply an inward pushing force to the synchronous push rod, causing the synchronous push rod to drive the limiting locking plate inward, thereby clamping the wooden board above the wooden board drilling frame. After the wooden board is drilled, the drilled wooden board is rotated and transferred to the front of the fixed support through the shifting support. During this process, the unlocking driven gear contacts the unlocking tooth plate and forms a gear and rack transmission. The movement of the unlocking driven gear causes it to roll on the unlocking tooth plate, driving the drive shaft to rotate. The unlocking driven gear inside the wooden board drilling frame rotates. Simultaneously, the unlocking driven gear rotates and forms a gear and rack transmission with the four push rods, driving the four push rods to push outward and compress the push rod springs. The edge of the wooden board above the wooden board drilling frame then separates from the limit locking plate, and the positioning structure is temporarily in a loose state. In this state, the drilled wooden board can be removed from the wooden board drilling frame, and an undrilled wooden board can be loaded. This achieves automatic clamping or loosening of the wooden board by the wooden board fixing mechanism without the need for manual control of the fixing mechanism, reducing the intensity of manual labor.
