[0040] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0041] See also Figure 1-Figure 3 The utility model provides the following technical solutions: a variable hole spacing high-efficiency drilling gearbox device, including a support platform 1 and a drilling mechanism 2, at least one set of drilling mechanisms 2 is fixed to the top of the support platform 1, and the drilling mechanism 2 includes: a No. 1 box body 21, a linkage gear set 22, a drive motor 23, a No. 2 box body 24, a transmission rod 25 and a pneumatic chuck 27.

[0042] Further, by Figure 1 and Figure 2 As shown, in this embodiment, the No. 1 housing 21 is fixed to the top of the support platform 1, the linkage gear set 22 is rotatably installed in the No. 1 housing 21, and the linkage gear set 22 includes a plurality of equally spaced driving gears 221 and a transition gear 222 located between two adjacent driving gears 221, the driving gear 221 is rotatably installed in the No. 1 housing 21 using the No. 1 rotating shaft 223, the transition gear 222 is rotatably installed in the No. 1 housing 21 using the No. 2 rotating shaft 224, and the transition gear 222 is meshed with the driving gear 221, the driving motor 23 is fixed to the top of the support platform 1, and is used to drive the driving gear 221 to rotate, the No. 2 housing 24 is fixed to the top of the support platform 1, a plurality of transmission rods 25 are distributed at intervals and rotatably installed in the No. 2 housing 24, and the transmission rods 25 are transmission-connected to the driving gear 221, and the pneumatic chuck 27 is fixed to One end of the transmission rod 25 is used to fix the drill bit. After adopting the above scheme, when in use, the drill bit is fixed by the pneumatic chuck 27. Multiple pneumatic chucks 27 can fix the drill bit at the same time. The driving motor 23 drives the driving gear 221 to rotate. The driving gear 221 drives the transition gear 222 to rotate through the meshing action, and at the same time drives the other driving gears 221 to rotate. The driving gear 221 drives the No. 1 rotating shaft 223 to rotate, and then drives the transmission rod 25 to rotate. The transmission rod 25 drives the drill bit to rotate through the pneumatic chuck 27 to realize the drilling operation. The multiple groups of drilling mechanisms 2 of the utility model can perform drilling operations at the same time, and the driving motor 23 of each group of drilling mechanisms 2 can drive multiple pneumatic chucks 27 to rotate at the same time. Multiple holes can be drilled on the permeable liquid core column in a single time. The processing efficiency is high, and the accuracy of the hole position can be guaranteed, thereby ensuring product quality.

[0043] It should be noted that, as can be seen from the figure, the present invention is provided with three sets of drilling mechanisms 2, and each set of drilling mechanisms 2 has 7 pneumatic chucks 27. Therefore, the three sets of drilling mechanisms 2 have a total of 21 pneumatic chucks 27, which can drill 21 holes on the permeable liquid core column at a time.

[0044] In addition, in theory, the three drilling mechanisms 2 can be combined into one group to achieve processing. However, due to the meshing relationship between each driving gear 221 and the transition gear 222, there is a torque between the driving gear 221 and the transition gear 222. When the length of the linkage gear group 22 is too long, its stability will also decrease. Therefore, designing multiple groups of identical drilling mechanisms 2 has higher stability.

[0045] It is also worth noting that the linkage gear set 22 disclosed in the present invention is only an exemplary mechanism. In other available embodiments, the driving gear 221 and the transition gear 222 can also be replaced by synchronous wheels and synchronous belts, and the driving gears 221 can be rotated synchronously through the transmission relationship between the synchronous wheels and the synchronous belts.

[0046] It should be further explained that the transition gear 222 disclosed in the present invention is only used to make the directions of the driving gears 221 consistent. In actual use, if there is no special requirement, the transition gear 222 may not be provided, that is, the driving gears 221 can be directly meshed with each other.

The transmission rod 25 is rotatably installed on the mounting block 242. After adopting the above scheme, when in use, the transmission rod 25 is supported by the mounting block 242. More specifically, the transmission rod 25 passes through the mounting block 242 and is rotatably connected to the mounting block 242 by a bearing.

[0049] Preferably, by Figure 1 and Figure 3As shown, in this embodiment, it also includes: a threaded column 244 and a locking nut 245. A waist-shaped hole 243 is processed on the fixing frame 241. The threaded column 244 is fixed to the top of the mounting block 242 and passes through the waist-shaped hole 243. The locking nut 245 is installed on the protruding end of the threaded column 244 by screwing. After adopting the above scheme, when in use, if necessary, the locking nut 245 can be loosened first, and the position of the mounting block 242 can be adjusted in the horizontal direction. The position of the pneumatic chuck 27 is adjusted to adjust the spacing between adjacent pneumatic chucks 27 to adapt to the drilling requirements of different spacings, and the adjustment is convenient and efficient.

[0051] Preferably, by Figure 1 and Figure 3 As shown, this embodiment also includes: a limit block 247, a plurality of limit blocks 247 are fixed at equal intervals in the fixed frame 241, and the limit blocks 247 are distributed between two adjacent mounting blocks 242. After adopting the above scheme, when in use, the two adjacent mounting blocks 242 are isolated by the limit blocks 247 to limit the adjustment range of the mounting blocks 242.

[0052] Preferably, by Figure 1 As shown, this embodiment also includes: a fixed seat 3 and a rodless cylinder slide 4. The fixed seat 3 is used to support the support platform 1. The two rodless cylinder slides 4 are symmetrically fixed to the top surface of the fixed seat 3 and are used to drive the support platform 1 to move. After adopting the above scheme, when in use, the support platform 1 is driven to move by the two rodless cylinder slides 4, so that the support platform 1 is close to or away from the permeate core column to be processed.

The two guide rails 5 are symmetrically fixed to the top surface of the fixed seat 3, and the guide slider 6 is fixed to the bottom surface of the support platform 1 and slides with the guide rail 5. After adopting the above scheme, when in use, the support platform 1 will drive the guide slider 6 to move along the guide rail 5 when moving, thereby improving the stability of the support platform 1.
