[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] This utility model provides, for example Figure 1-3 The device shown is a wood board drilling device for civil engineering, including a table 1. A drilling motor 12 is installed at the top of the table 1. A drilling drill bit 13 is fixedly connected to the output shaft of the drilling motor 12. An electric telescopic rod 11 is fixedly connected to the top of the drilling motor 12. The drilling motor 12 provides rotational power to the drilling drill bit 13. When the electric telescopic rod 11 and the drilling motor 12 are started, the electric telescopic rod 11 drives the drilling motor 12 and the drilling drill bit 13 to move downward, thereby driving the drilling drill bit 13 to drill holes in the wood board.

[0026] Preferably, a rotating assembly is disposed at the top of the electric telescopic rod 11 for adjusting the angle of the drilling bit 13. The rotating assembly includes a U-shaped block 8, with a disc 9 disposed on the inner side of the U-shaped block 8. A rotating rod 10 is fixedly inserted and connected to the middle of one side of the disc 9. The two ends of the rotating rod 10 are rotatably inserted and connected to the inside of the U-shaped block 8. The bottom end of the outer wall of the disc 9 is fixedly connected to the top of the electric telescopic rod 11. A locking assembly is disposed on one side of the U-shaped block 8 for locking the disc 9. The locking assembly includes a first threaded hole 14. A threaded hole 14 is provided on one side of the U-shaped block 8. A locking bolt 15 is inserted into the internal thread of the first threaded hole 14. One end of the locking bolt 15 located inside the first threaded hole 14 abuts against the outer wall of the disc 9. By rotating the locking bolt 15, the locking bolt 15 is released from fixing the disc 9. The disc 9 is rotated inside the U-shaped block 8. When the indicator arrow 16 at the end of the rotating rod 10 points to the angle to be adjusted, the locking bolt 15 is rotated again to lock and fix the disc 9.

[0027] Preferred, an indicator mark is located on the other side of the U-shaped block 8 for indicating the rotation angle of the disk 9. The indicator mark includes a scale line 17, which is located on the outer wall of the other side of the U-shaped block 8. An indicator arrow 16 is provided at the other end of the rotating rod 10, such as... Figure 3 In the diagram, the scale indicated by the arrow 16 is the zero mark. By setting the scale line 16 and the arrow 17, the angle of the drilling bit 13 can be precisely adjusted.

[0028] Furthermore, a moving mechanism for moving the drill bit 13 is provided above the tabletop 1. The moving mechanism includes a bracket 2, a first screw 3 rotatably connected to the inner side of the bracket 2, a second motor 4 fixedly connected to one end of the first screw 3, a moving block 6 fixedly connected to the top of the U-shaped block 8, a second threaded hole 7 provided on one side of the moving block 6, the outer wall of the first screw 3 threadedly inserted into the inner wall of the second threaded hole 7, a limit groove 5 provided at the top of the inner side of the bracket 2, and the outer wall of the top of the moving block 6 sliding against the inner wall of the limit groove 5. The bottom end of the movable block 6 is fixedly connected to the top end of the U-shaped block 8. The second motor 4 is started, and the second motor 4 drives the first screw 3 to rotate. The first screw 3 is threadedly connected to the movable block 6. The first screw 3 drives the movable block 6 to move along the limiting groove 5 under the limiting position of the limiting groove 5, thereby driving the drilling bit 13 to move. When the first screw 3 drives the movable block 6 to move, the limiting groove 5 plays a limiting and guiding role. The limiting groove 5 can prevent the movable block 6 from rotating under the action of the first screw 3.

[0029] Furthermore, the top of the tabletop 1 is equipped with a fixing mechanism for the wooden board. The fixing mechanism includes two uprights 18, which are fixedly connected to the top of the tabletop 1. An inner groove 19 is provided on the opposite side of the two uprights 18. A second screw 20 is rotatably connected inside the inner groove 19. A pressure block 22 is threadedly connected to the outer wall of the second screw 20. A third motor 21 is fixedly connected to the top of the second screw 20. The pressure block 22 is L-shaped and used to fix the wooden board. When the wooden board is placed on the top of the tabletop 1, the third motor 21 is started. The third motor 21 drives the second screw 20 to rotate. Utilizing the threaded connection between the second screw 20 and the pressure block 22, the second screw 20 drives the pressure block 22 to move downward, thereby fixing the wooden board. This ensures that the wooden board will not move during the drilling process of the drill bit 13.

[0030] This utility model provides a method for using a wooden board drilling device for civil engineering, including the following steps:

[0031] Step 1: When fixing the board, place the board on top of the tabletop 1, start the third motor 21, and use the cooperation of the pressure block 22, the second screw 20 and the inner groove 19 to drive the pressure block 22 to fix the board.

[0032] Step two, when adjusting the drilling bit 13, rotate the locking bolt 15 to allow the disc 9 to rotate, rotate the indicator arrow 16 at the end of the rotating rod 10 to a suitable angle, and rotate the locking bolt 15 again to lock and fix the disc 9.

[0033] Step 3: Drilling holes in the wooden board. By starting the electric telescopic rod 11 and the drilling motor 12, the drilling drill 13 is driven to drill holes in the wooden board. The second motor 4 is started, which drives the first screw 3 to rotate. The first screw 3 drives the moving block 6 to move, so that the drilling drill 13 drills holes in the wooden board.

[0034] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
