[0036] Working principle:

[0037] When in use, the pipes 11 to be drilled are stacked and placed in the rack 3, and then the third motor 23 is started. The output end of the third motor 23 drives the third shaft 24 to rotate. The rotation of the third shaft 24 causes the supporting plate 5 to slide to the bottom of the rack 3, and the supporting groove 4 is opposite to the bottom opening of the rack 3. The pipes 11 in the rack 3 fall into the supporting groove 4, and then the third motor 23 is started again to drive the supporting plate 5 away from the rack 3 to the top of the storage groove 10;

[0038] Then, the first motor 13 is started, and the output end of the first motor 13 drives the first rotating shaft 14 to rotate, and the rotation of the first rotating shaft 14 drives the gear 15 to rotate, so that the gear 15 moves on the rack 16, so that the start of the first motor 13 drives the push block 6 to move, so that the push block 6 extends into the supporting groove 4 and contacts the pipe 11;

[0039] Then the cylinder 25 is started, and the telescopic end of the cylinder 25 drives the working block 2 and the three-jaw chuck No. 2 8 to move to the same horizontal plane as the pipe 11. At this time, the pushing block 6 pushes the pipe 11 through the support rod 22 and makes it close to the three-jaw chuck No. 2 8, and then the three-jaw chuck No. 2 8 is started, and the three-jaw chuck No. 2 8 clamps one end of the pipe 11;

[0040] Then start the cylinder 25 again, the telescopic end of the cylinder 25 drives the three-jaw chuck No. 2 8 and the pipe 11 to move upward to the same level as the three-jaw chuck No. 1 7, and then start the three-jaw chuck No. 1 7 to clamp the other end of the pipe 11.

[0041] At the same time, the third motor 23 is started to drive the supporting plate 5 to slide to the bottom of the rack 3 to receive the next pipe 11;

[0042] Then, the drilling device 9 is started, and the second motor 19 is started. The output end of the second motor 19 drives the second rotating shaft 20 to rotate. The rotation of the second rotating shaft 20 drives the three-jaw chuck No. 2 8, the pipe 11 and the three-jaw chuck No. 1 7 to rotate to cooperate with the drilling device 9 to drill holes on the surface of the pipe 11.

[0043] After the drilling is completed, the three-jaw chuck No. 2 8 releases the clamping of the pipe 11, and the first motor 13 is started at this time, and the three-jaw chuck No. 1 7 drives the pipe 11 away from the three-jaw chuck No. 2 8 to move above the storage slot 10, and then the three-jaw chuck No. 1 7 releases the clamping of the pipe 11, and the pipe 11 falls into the storage slot 10;

[0044] Then the third motor 23 is started again to drive the support plate 5 to slide to the top of the storage slot 10, and then the next pipe 11 is drilled, and the cycle is repeated;

[0045] Finally, the staff member holds the insertion rod 28 and moves it upward, then rotates the cover plate 26 to take out the pipe 11 in the storage tank 10, and the whole operation is completed.

[0046] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
