[0032] For the quick hole-opening device for round pipes with different diameters provided in this embodiment, after the positioning and pressing member presses and positions the round pipe, the lifting cylinder 13 drives the lifting plate 12 to move downward, and at the same time the drilling tool 14 starts, and the drilling tool 14 processes the round pipe by drilling; during the drilling operation, a set of diameter lines of the round pipe are in a vertical state with the horizontal plane 10 and are located at the vertical plane 9, so as to realize the quick and accurate positioning between the pressing and hole-opening mechanism and the round pipe, ensure that the drill bit on the round pipe coincides with the diameter line of the round pipe, and ensure the hole-opening accuracy of the round pipe; and the pneumatic slide table 15 can drive the drill to move along the axial direction of the round pipe, so as to meet the hole-opening requirements of the round pipe in the axial direction and further improve the applicability of the device.

[0038] For the rapid hole-opening device for round tubes with different diameters provided in this embodiment, the second roller assembly 3 is moved and adjusted, so as to adaptively adjust the distance between the first roller assembly 2 and the second roller assembly 3 to meet the supporting requirements for round tubes with multiple pipe diameters.

[0039] By starting the driving motor 17, the driving motor 17 drives the roller on the first roller assembly 2 to rotate, so as to rotate the round tube and perform rotational adjustment on the position of the round tube to meet the processing requirements for circumferential drilling of the round tube, and further improve the applicability of the device.

[0040] Rotate the first adjusting screw 19. After being transmitted by the synchronous transmission member, the sliding seat 18 moves along the sliding arm 4, so that the two rollers are located above the middle of the round tube.

When drilling the same type of batch of round tubes, the bubble level 23 can be used to detect whether the gantry 6 is in a horizontal state, thereby assisting in detecting whether the drill is in a vertical state. The perpendicularity of the drill can be adjusted through the bubble level 23 and the horizontal and vertical adjusters to ensure the perpendicularity of the drill, so as to ensure that the drill can perform precise drilling on the round tube.

[0043] The usage process of the rapid hole-opening device for round tubes with different diameters provided by the present utility model is as follows: Adjust the distance between the first idler wheel assembly 2 and the second idler wheel assembly 3 to be less than the diameter of the round tube, place the round tube between the first idler wheel assembly 2 and the second idler wheel assembly 3 on the two supporting assemblies, and adaptively adjust the position of the drill through the horizontal and vertical adjusters and the bubble level 23 so that the drill is exactly above the center of the round tube, and the drilling end of the drill coincides with the diameter line at the vertical plane of the round tube. The limiting air cylinder 22 locks the corresponding roller, and the synchronous lifting driver 5 is started to drive the two sliding arms 4 to move downward until both the pressing wheels 8 are in close contact with the outer wall of the round tube, and then the drill can be used to perform radial drilling on the round tube.

[0044] In the present utility model, unless otherwise clearly defined and limited, terms such as "installation", "connection", "connection", "fixation" and the like shall be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral body; it can be a mechanical connection, an electrical connection or communication with each other; it can be directly connected, or indirectly connected through an intermediate medium, and can be the communication inside two components or the interaction relationship between two components, unless otherwise clearly defined.
