[0033] Example 1

[0034] like Figure 1-5 As shown, the present invention proposes a tank end cap leveling device, which includes a worktable 1, a reset assembly 3, a limit rod and a lifting assembly;

[0035] The workbench 1 has a placement slot 2 in the middle, and the two ends of the placement slot 2 are connected.

[0036] There are two limiting rods, which are symmetrically installed on the inner wall of the placement groove 2 and extend to the side of the placement groove 2.

[0037] The lifting assembly is installed on both sides of the top of the worktable 1 and above the placement slot 2, and the bottom of the middle part is connected to the side of the limit rod; wherein, the top of the inner side of the lifting assembly has a leveling roller assembly (not shown in the figure).

[0038] The reset assembly 3 is installed on the side of the workbench 1 and extends into the inner side of the placement slot 2 to connect with the limit rod.

[0039] In this embodiment, the oil tank end cap is placed on the workbench 1 through the placement groove 2 for leveling. When the leveling roller assembly is moved towards the oil tank end cap by the lifting assembly, the lifting assembly contacts the limiting rod and squeezes the limiting rod, causing the limiting rod to move towards the center of the placement groove 2 and contact the oil tank end cap. This limits the position of the oil tank end cap. At the same time, the limiting rod drives the reset assembly 3 to stretch. After the oil tank end cap is leveled, the lifting assembly drives the leveling roller assembly to move upward, so that the limiting rod is reset by the reset assembly 3, restoring the device to its initial state. This achieves continuous, rapid, and precise leveling of the oil tank end cap, and the operation is simple, greatly improving production efficiency.

[0040] Example 2

[0041] like Figure 5 As shown, the present invention proposes a flattening device for an oil tank end cap. The difference between this embodiment and the first embodiment is that the limiting rod includes a stop rod 5 and an adjusting rod 11.

[0042] The stop bar 5 is located inside the placement groove 2. The stop bar 5 is U-shaped and is used to limit the two sides of the oil tank end cover on the inner wall of the placement groove 2 during use, while also limiting the two ends of the oil tank end cover.

[0043] The number of adjusting rods 11 is at least two. The two adjusting rods 11 are respectively installed on one side of the stop 5 and extend to the side of the worktable 1 and are movably connected to the lifting assembly.

[0044] In an optional embodiment, the inner two walls of the placement groove 2 are provided with mounting grooves 4, the stop bar 5 is located inside the mounting groove 4, and the other side of the stop bar 5 is flush with the inner wall of the placement groove 2, so as to prevent the end of the fuel tank end cap from contacting the end of the stop bar 5 during use, so that the fuel tank end cap cannot be placed inside the placement groove 2.

[0045] In an optional embodiment, one end of the adjusting rod 11 has an upwardly oriented inclined surface, and the top edge of the inclined surface is flush with the side edge of the worktable 1, so that the lifting assembly can directly contact the inclined surface of the adjusting rod 11 during use and exert pressure on the adjusting rod 11 through the inclined surface.

[0046] In this embodiment, the inclined surface of the adjusting rod 11 is used to make the lifting assembly contact the inclined surface of the adjusting rod 11 when it moves down. During the continuous downward movement, the adjusting rod 11 drives the stop rod 5 to move inward to the placement groove 2, so that the stop rod 5 contacts the fuel tank end cover and the two ends of the stop rod 5 limit the two ends of the fuel tank end cover, so that the position of the fuel tank end cover is more accurate and the fuel tank end cover is prevented from shifting during the leveling process.

[0047] Example 3

[0048] like Figure 1-3 As shown, the present invention proposes a flattening device for the end cap of an oil tank. Compared with the first embodiment, the difference in this embodiment is that the lifting assembly includes a lifting plate 8, a cylinder 9 and a connecting plate 12.

[0049] There are multiple cylinders 9, and multiple cylinders 9 are respectively arranged on both sides of the worktable 1;

[0050] The lifting plate 8 is installed on the top of the cylinder 9 and is located above the placement slot 2;

[0051] There are two connecting plates 12. The two connecting plates 12 are symmetrically installed at the bottom of the lifting plate 8 and located between the worktable 1 and the cylinder 9. The bottom of the connecting plate 12 is slidably connected to the side of the worktable 1 and movably connected to the stop bar 5.

[0052] In an optional embodiment, a slide bar 10 is provided on the side of the workbench 1, and a slide groove 6 is provided on the side of the connecting plate 12. When the connecting plate 12 and the workbench 1 are installed together, the slide bar 10 is accommodated in the slide groove 6 to prevent the connecting plate 12 from bending during use.

[0053] In this embodiment, when the lifting plate 8 is moved downward by the cylinder 9, the lifting plate 8 causes the connecting plate 12 to slide on the side of the workbench 1, and the bottom end of the connecting plate 12 contacts the inclined surface of the adjusting rod 11. As the adjusting rod 11 continues to move downward, the connecting plate 12 moves the adjusting rod 11 towards the inside of the placement groove 2 through the inclined surface, so that the adjusting rod 11 moves the stop rod 5 towards the middle of the placement groove 2 and stretches the reset assembly 3. After leveling is completed, the cylinder 9 moves the lifting plate 8 upward, so that the connecting plate 12 separates from the adjusting rod 11, and the tension is released by the reset assembly 3, realizing the rapid reset of the stop rod 5.

[0054] Example 4

[0055] like Figure 4 As shown, the present invention proposes a flattening device for an oil tank end cap. Compared with the first embodiment, the difference in this embodiment is that the reset component 3 includes a sleeve 31, a connecting cylinder 32, a spring 33, and a bolt 34.

[0056] Sleeve 31 is disposed on the side of worktable 1;

[0057] The connecting sleeve 32 is inserted into the inner side of the sleeve 31 and connected to the stop rod 5 by bolt 34;

[0058] Spring 33 is located inside the connecting cylinder 32 and its two ends are connected to the sleeve 31 and the connecting cylinder 32 respectively.

[0059] In an optional embodiment, a notch 7 is provided at the bottom center of the connecting plate 12, and the length and width of the notch 7 are both greater than the diameter of the sleeve 31.

[0060] In this embodiment, the connecting cylinder 32 is connected to the stop rod 5 by bolt 34. While the stop rod 5 is moved by the force of the adjusting rod 11, the stop rod 5 drives the connecting cylinder 32 to slide inside the sleeve 31 through the bolt 34. At the same time, the connecting cylinder 32 stretches the spring 33, so that the spring 33 generates a pulling force on the connecting cylinder 32. The spring 33 is then released by the adjusting rod 11, so that the stop rod 5 is reset by the pulling force of the spring 33 and returns to its initial state for the next operation.

[0061] In summary, in this utility model, by placing the fuel tank end cap inside the placement groove 2 and simultaneously moving the lifting plate 8 downwards via the cylinder 9, the lifting plate 8 causes the connecting plate 12 to slide on the side of the workbench 1, making the bottom end of the connecting plate 12 contact the inclined surface of the adjusting rod 11. The continuous downward movement of the adjusting rod 11 causes the connecting plate 12 to move the adjusting rod 11 towards the inside of the placement groove 2 via the inclined surface, causing the adjusting rod 11 to move the stop rod 5 towards the center of the placement groove 2, making the stop rod 5 contact the fuel tank end cap, and causing the two ends of the stop rod 5 to... The end cap of the oil tank is limited at both ends. At the same time, the stop rod 5 drives the connecting cylinder 32 to slide inside the sleeve 31 through the bolt 34. The connecting cylinder 32 drives the spring 33 to stretch, so that the spring 33 generates a pulling force on the connecting cylinder 32. After leveling is completed, the cylinder 9 drives the lifting plate 8 to move up, so that the connecting plate 12 is separated from the adjusting rod 11. At the same time, the pulling force of the spring 33 drives the stop rod 5 to reset and return to the initial state for the next operation. This makes the oil tank end cap leveling continuous, fast and accurate, and easy to operate, which greatly improves production efficiency.

[0062] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
