[0013] Compared with the prior art, the beneficial effects of the present invention are: 1. The mounting connection bases 1, 2, 3, and 4 on both sides of the processing middle seat can be lifted up and down. Moreover, the mounting connection bases 1, 2, 3, and 4 can be lifted individually. And the mounting connection bases 1, 2, 3, and 4 are all connected to the processing middle seat by an up-and-down connection structure. When the length of the steel pipe placed on the processing middle seat is insufficient, the lengths can be spliced and extended through the mounting connection bases 1, 2, 3, and 4 to adapt to the length of the steel pipe. The up-and-down connection between the processing middle seat and the mounting connection bases 1, 2, 3, and 4 on both sides is mainly through the pneumatic telescopic rods 1 installed respectively. When the mounting connection bases 1 on both sides rise to be flush with the processing middle seat, it is mainly driven by two pneumatic telescopic rods 1 to slide the mounting slide bases 1 on the sides of their respective mounting connection bases upward in the mounting chute 1 on both sides of the processing middle seat until the mounting slide base 1 is aligned with the top of the mounting chute 1. In this way, the mounting connection bases 1 on both sides are flush with the top of the processing middle seat to increase the length. If you want to increase the length again, the pneumatic telescopic rod 1 is used to drive the mounting connection base 2 to rise, connect and align the mounting slide base 2 on the mounting connection base 2 with the mounting chute 2 on the mounting connection base 1. If you want to lengthen the length further, continue to raise the mounting connection bases 3 and 4 to lengthen the two sides of the processing middle seat. In this way, when drilling the steel pipe, in the face of steel pipes of various lengths, workers do not need to replace the equipment to place steel pipes of different lengths and can automatically adjust to the appropriate length. 2. There are two opposite electric telescopic rods 2 on each of the mounting connection bases 1, 2, 3, and 4. The two electric telescopic rods 2 drive the positioning clamp 2 synchronously to approach and adapt to the specification of the diameter of the steel pipe and clamp it firmly. The positioning clamp 1 on the processing middle seat is also driven by the synchronous electric telescopic rod 1 to clamp and fix the steel pipe, and can be adjusted in size to adapt to clamping and stabilizing steel pipes of different diameter specifications. 3. After the steel pipe body is clamped and drilled, some debris generated during drilling is driven by the motor 1 to rotate the fan. The strong wind generated by the fan blows out through the stretched air duct to blow the debris down. 4. The electric telescopic rod 3 drives the auxiliary external gear long wheel at the lower part of the mounting plate to approach above the clamped steel pipe body synchronously. Then, the auxiliary external gear long wheel is driven by the micro electric telescopic rod to be close to the steel pipe body. Finally, the motor 2 drives the auxiliary external gear long wheel to rotate, and the rotation of the auxiliary external gear long wheel will turn over the steel pipe body and turn over the surface position of the steel pipe body.

The electric telescopic rods three 41 drive the auxiliary external gear long wheel 45 at the lower part of the mounting plate 42 to approach above the clamped steel pipe body 35 synchronously, and then the micro electric telescopic rods 43 drive the auxiliary external gear long wheel 45 to be close to the steel pipe body 35 synchronously. Finally, the second motor 47 drives the auxiliary external gear long wheel 45 to rotate, and the rotation of the auxiliary external gear long wheel 45 will turn the steel pipe body 35 to turn the surface position of the steel pipe body 35.

[0021] A top platform 30 is installed on the top of the fixed seat 3. An activity groove 33 is arranged in the middle of the top platform 30. An activity block 32 is slidably connected in the activity groove 33. The left side of the activity block 32 is detachably connected to the output end of the second pneumatic telescopic rod 31. A limit auxiliary frame 34 is installed on the top of the activity block 32. The steel pipe body 35 is arranged inside the limit auxiliary frame 34. By placing the steel pipe body 35 inside the limit auxiliary frame 34, and then the second pneumatic telescopic rod 31 drives the activity block 32 and the limit auxiliary frame 34 to move in the activity groove 33 to the position of the equipment rack 1.

[0022] A plurality of placement grooves 48 are arranged inside the fixed seat 3, and the plurality of placement grooves 48 can store the steel pipe body 35.

[0023] The two first mounting connectors 12, the two second mounting connectors 13, the two third mounting connectors 14, and the two fourth mounting connectors 15 are all on the same plane as or lower than the machining middle seat 7. The machining middle seat 7 is fixed. The first mounting connector 12, the second mounting connector 13, the third mounting connector 14, and the fourth mounting connector 15 can be driven by their respective pneumatic telescopic rods 24 to rise to the same plane as the machining middle seat 7 or lower than the machining middle seat 7 to adjust the length.

[0024] Multiple second clamping inner frames 28 and the first clamping inner frame 9 are all in contact with the steel pipe body 35. The steel pipe body 35 is in contact with the auxiliary external gear long wheel 45. The auxiliary external gear long wheel 45 is driven by the second motor 47 to rotate to turn over the steel pipe body 35.

[0025] There are multiple groups of two second electric telescopic rods 26, and the two second electric telescopic rods 26 in each group are synchronously controlled. As Figure 7 and Figure 8 shown, the two second electric telescopic rods 26 on the first mounting connector 12 are synchronously controlled, the two second electric telescopic rods 26 on the second mounting connector 13 are synchronously controlled, the two second electric telescopic rods 26 on the third mounting connector 14 are synchronously controlled, and the two second electric telescopic rods 26 on the fourth mounting connector 15 are synchronously controlled.

[0026] In the present invention, since the machining middle seat 7 is fixed, the first clamping inner frame 9 mounted on the machining middle seat 7 is also fixed. The machining middle seat 7 and the first clamping inner frame 9 are used to place the steel pipe to be drilled. The first mounting connector 12, the second mounting connector 13, the third mounting connector 14, and the fourth mounting connector 15 sequentially arranged on both sides of the machining middle seat 7 are for increasing the length on both sides of the machining middle seat 7 to adapt to the placement of the steel pipe. The first mounting connector 12, the second mounting connector 13, the third mounting connector 14, and the fourth mounting connector 15 on both sides of the machining middle seat 7 can be lifted up and down, and the first mounting connector 12, the second mounting connector 13, the third mounting connector 14, and the fourth mounting connector 15 can all be lifted and lowered independently, and there is a connecting up-and-down structure between the first mounting connector 12, the second mounting connector 13, the third mounting connector 14, and the fourth mounting connector 15 and the machining middle seat 7. When the length of the steel pipe placed on the machining middle seat 7 is insufficient, the length can be spliced and extended through the first mounting connector 12, the second mounting connector 13, the third mounting connector 14, and the fourth mounting connector 15 to adapt to the length of the steel pipe for placement. As Figure 7 and Figure 8As shown in the figure, the connection between the processing middle seat 7 and the installation connection seats one 12, two 13, three 14 and four 15 on both sides is mainly through the pneumatic telescopic rods one 24 installed respectively. When the installation connection seats one 12 on both sides rise to be flush with the processing middle seat 7, mainly through the two pneumatic telescopic rods one 24 simultaneously driving the installation sliding seats one 19 on one side of their respective installation connection seats one 12 to slide upward in the installation sliding grooves one 8 on both sides of the processing middle seat 7 until the installation sliding seats one 19 are aligned with the tops of the installation sliding grooves one 8. In this way, the installation connection seats one 12 on both sides are flush with the top of the processing middle seat 7 to increase the length. If you want to increase the length again, then the pneumatic telescopic rod one 24 drives the installation connection seat two 13 to rise, connects and aligns the installation sliding seat two 20 on the installation connection seat two 13 with the installation sliding groove two 16 on the installation connection seat one 12. If you want to lengthen the length further, then continue to raise the installation connection seats three 14 and four 15 to lengthen the two sides of the processing middle seat 7. In this way, when the steel pipe is facing steel pipe sizes of various lengths at the drilling surface, the worker does not need to replace the equipment to place and deal with steel pipes of different lengths, and automatically adjusts to the appropriate length.

[0027] There are two opposite electric telescopic rods two 26 on each of the installation connection seats one 12, two 13, three 14 and four 15. The two electric telescopic rods two 26 synchronously drive the positioning clamp two 29 to approach and adapt to the specifications of the steel pipe diameter, and carry out firm clamping. The positioning clamp one 10 on the processing middle seat 7 is also driven by the synchronous electric telescopic rod one 50 to clamp and fix the steel pipe, and can adjust the size to adapt to and firmly clamp steel pipes of different diameter specifications.

[0028] After the steel pipe body 35 is clamped, drilling is carried out. Some debris generated during drilling is driven by the motor one 36 to rotate the fan 38. The strong wind generated by the fan 38 blows out through the stretching air duct 40 to blow down the debris.

[0029] The electric telescopic rod three 41 synchronously drives the auxiliary external gear long wheel 45 at the lower part of the installation plate 42 to approach above the clamped steel pipe body 35. Then, the micro electric telescopic rod 43 synchronously drives the auxiliary external gear long wheel 45 to approach the steel pipe body 35. Finally, the motor two 47 drives the auxiliary external gear long wheel 45 to rotate. The rotation of the auxiliary external gear long wheel 45 will turn over the steel pipe body 35 and turn over the surface position of the steel pipe body 35.
