[0031] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention 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 invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention. Example

[0032] Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 A drilling device for an oil tank shell includes a base 1 and a drilling assembly 8. A vertical plate 2 is mounted on one side of the top of the base 1, and a positioning rod 9 is mounted in the middle of one side of the vertical plate 2. A bracket 3 is mounted on the other side of the top of the base 1, and a driver 4 is provided on one side of the bracket 3. A rotating assembly 7 is mounted on the top of the bracket 3 to drive the drilling assembly 8 to drill holes in the oil tank shell. The rotating assembly 7 includes a rotating component 71, a connecting component 72 on one side of the rotating component 71, and a drilling rod 73 on one side of the connecting component 72. One end of the drilling rod 73 has a connecting groove 74. A rotating groove 5 is provided on the top of the bracket 3, and one end of the rotating component 71 is rotatably connected to the inner wall of the rotating groove 5. The driver 4 is specifically a motor, and its output end is drively connected to one end of the rotating component 71. One end of the connecting component 72 is rotatably connected to the other end of the rotating component 71, and the other end of the connecting component 72 is rotatably connected to the inner wall of the connecting groove 74. The other end of the punch rod 73 has a through hole 75, and a cylinder 6 is fixedly connected to one side of the top of the bracket 3. The middle part of the punch rod 73 is slidably connected to the inner wall of the cylinder 6.

[0033] A drilling assembly 8 is disposed on one side of the upright plate 2 for drilling holes in the outer shell of the fuel tank. The drilling assembly 8 includes a drill 81, one end of which has a circular groove 83. A rod 84 is fixedly connected to one side of the inner wall of the circular groove 83, and the rod 84 is movably embedded in one end of the drilling rod 73. A fixing groove 82 is provided in the middle of both the drill 81 and the rod 84. A threaded rod 85 is provided on one side of the fixing groove 82. The fixing groove 82 is directly opposite the through hole 75, and the drill 81 is directly opposite the positioning rod 9. The threaded rod 85 passes through the interior of the fixing groove 82 and the through hole 75, and a threaded ring 86 is threadedly connected to one end of the threaded rod 85.

[0034] It is worth mentioning that the output of the driver 4 drives the rotating part 71 to rotate around the position of the rotating groove 5, which in turn drives the other end of the rotating part 71 to make a circular motion around the rotating groove 5. In this way, the end of the connector 72 connected to the rotating part 71 rotates synchronously, and the other end of the connector 72 can drive the punching rod 73 to move back and forth inside the cylinder 6.

[0035] Furthermore, when the connector 72 is sleeved on the outside of the rotating part 71, the end of the punch 81 is away from the positioning rod 9. At this time, the oil tank can be sleeved on the top of the vertical plate 2. When the connector 72 is in the state shown in the figure of the vertical plate 2, one end of the punch 81 will be sleeved on the outside of the positioning rod 9. In this way, the outer shell of the oil tank can be punched.

[0036] The positioning rod 9 is supported inside the fuel tank. When the punch 81 passes through the fuel tank shell to make a hole, the positioning rod 9 can support the inner wall of the fuel tank shell to prevent the fuel tank shell from deforming and being damaged.

[0037] With the above structural design, the punch 81 is installed at one end of the punch rod 73. The end of the punch 81 near the positioning rod 9 is very sharp and is used to punch holes in the outer shell of the oil tank.

[0038] The insertion rod 84 is inserted into one end of the punching rod 73, and the circular groove 83 is sleeved on one end of the punching rod 73. The stacked connection increases the contact area between the puncher 81 and the punching rod 73, increases friction, and improves connection stability.

[0039] The threaded rod 85 is inserted into the fixed groove 82 and the through hole 75. The threaded ring 86 is threaded onto one end of the threaded rod 85. In this way, the punch 81 is fixed to one end of the punch rod 73. This method allows the punch 81 to be disassembled and replaced at any time if the punch end is worn, thus improving the flatness of the punch edge.

[0040] The process of using the fuel tank outer shell drilling device provided by this utility model is as follows: The fuel tank is fitted onto the outside of the upright plate 2, so that the side wall of the fuel tank where the hole needs to be drilled is in contact with the end of the positioning rod 9. The driver 4 is started. The output end of the driver 4 is connected to the position of the rotating part 71 located on the inner wall of the rotating groove 5. That is, the output end of the driver 4 drives the rotating part 71 to rotate around the position of the rotating groove 5 as the center. Then, the other end of the rotating part 71 moves in a circular motion to drive one end of the connecting part 72 to rotate synchronously. In this way, the other end of the connecting part 72 can drive the drilling rod 73 to move back and forth inside the cylinder 6, thereby driving the drill 81 to move back and forth. When the output end of the driver 4 drives the rotating part 71 to rotate so that the drilling rod 73 moves away from the side of the positioning rod 9, the fuel tank is fitted onto the top of the upright plate 2 so that the position to be drilled corresponds to it. When the output end of the driver 4 drives the drill 81 to move to the position corresponding to the positioning rod 9, the fuel tank outer shell can be drilled. The positioning rod 9 corresponds to the position of the punch 81, which can enhance the hardness of the area around the punched part of the fuel tank shell, making the fuel tank shell less prone to deformation and damage after punching.
