[0002] In the furniture manufacturing industry, the use of large panels is becoming increasingly widespread, and the requirements for the processing quality and efficiency of large panels are also becoming higher. Large panels used in furniture manufacturing usually require corresponding holes to be drilled on two opposite sides. When drilling holes on the sides of large panels, traditional drilling devices can usually only drill one side at a time, and then flip the large panel to drill the other side. It is often difficult to ensure that the holes on the two sides are completely aligned. This operation method is very cumbersome and requires frequent manual flipping of the large panel, which not only increases the labor intensity, but also easily damages the board and greatly reduces production efficiency.

The piston rod of the retracting rod 16 passes through the lower part of the crossbeam 15 and is fixedly connected to the upper surface of the cross rail 17. A positive and negative threaded rod 20 is rotatably installed in the slide groove 19 of the cross rail 17. A servo motor 28 is fixedly installed at one end of the cross rail 17. The output shaft of the servo motor 28 is fixedly connected to the positive and negative threaded rod 20. The left slider 21 and the right slider 22 are respectively connected to the positive and negative threads on the positive and negative threaded rod 20. A servo motor 3 25 and a servo motor 4 26 are fixedly installed on one side end face of the left connecting block 23 and the right connecting block 24 near the lower end. The output shafts of the servo motor 3 25 and the servo motor 4 26 pass through the left connecting block 23 and the right connecting block 24 respectively and are threadedly connected to the drill chuck 1 27 and the drill chuck 29. The left drill 28 and the right drill 30 are fixedly connected to the drill chuck 1 27 and the drill chuck 29 respectively by mechanical clamping.

[0027] Working principle: During use, the large plate to be drilled is fixed on the worktable 1 using existing tooling such as clamps and suction cups to ensure that the large plate will not move during drilling. The servo motor 5 drives the reciprocating screw 4 to rotate. Since the left slide 6 is threaded to the reciprocating screw 4, the left slide 6 will slide along the left end face on the worktable 1. At the same time, the right slide 10 moves synchronously with the left slide 6 under the constraint of the guide rod 9. The left column 11 and right column 13 at the upper end of the left slide 6 and right slide 10 also move accordingly, thereby driving the left drill bit 28. The left drill bit 28 and the right drill bit 30 move together. By precisely controlling the rotation angle of the servo motor 15, the left drill bit 28 and the right drill bit 30 can be accurately positioned at corresponding positions on the two sides of the large plate. The electric telescopic rod 16 on the upper surface of the crossbeam 15 can drive the cross rail 17 to move up and down, thereby adjusting the height of the left drill bit 28 and the right drill bit 30 so that the left drill bit 28 and the right drill bit 30 are moved to the appropriate height. The positive and negative threaded rods 20 are rotatably installed in the slide groove 19 of the cross rail 17. The positive and negative threaded rods 20 are driven to rotate by the servo motor 28. Since the left slider 2 Slider 21 and right slider 22 are respectively connected to the positive and negative threads on the positive and negative thread screw 20. When the positive and negative thread screw 20 rotates, slider 21 and right slider 22 will move towards or away from each other, thereby driving left connecting block 23 and right connecting block 24, as well as left drill bit 28 and right drill bit 30 to move. This allows the spacing between left drill bit 28 and right drill bit 30 to be adjusted according to the width of the large board, adapting to the side drilling requirements of large boards of different widths. After left drill bit 28 and right drill bit 30 are positioned, servo motor 3 25 and servo motor 4 26 are started to drive the drills. The head chuck 27 and drill chuck 29 rotate. Simultaneously, the control system controls the left drill bit 28 and right drill bit 30 to feed to the side of the large plate for drilling. The drill chucks are screwed clockwise onto the output shafts of servo motors 25 and 26 via threaded connections. Utilizing the self-locking characteristic of the threads, the drill bits are subjected to axial force and torque, preventing the drill chucks from easily loosening. After the drilling operation is completed, the control system stops the rotation of servo motors 25 and 26, and also stops the rotation of left drill bit 28 and right drill bit 30. Then, the electric telescopic rod 16 is controlled to move the horizontal rail 17 upward, causing left drill bit 28 and right drill bit 30 to leave the large plate. Finally, the large plate fixed on the worktable 1 is removed, completing the entire drilling process.
