[0019] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0020] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0022] Example 1:

[0023] like Figure 1 As shown in Figure 2, a fuel tank assembly tooling for positioning the tank body includes a base 1. The base 1 includes a first platform 11, a second platform 12, and a third platform 13. The first platform 11 is lower than the second platform 12, and the second platform 12 is lower than the third platform 13. Both the third platform 13 and the first platform 11 are provided with clamping units. The two clamping units respectively position the left side plate 72 and the right side plate of the tank body. The side of the third platform 13 facing the first platform 11 is used to position the bottom plate of the tank body. The second platform 12 is provided with a rear support unit, which is used to position the rear side plate of the tank body. The tooling also includes a marking template with marking grooves. The marking template includes a left side plate 72 template, an upper cover plate 73 template, and a front side plate 71 template.

[0024] First, the side panels and top cover 73 of the mailbox are laid out and marked using a marking template. Small parts are then installed. The first platform 11 is lower than the second platform 12, and the second platform 12 is lower than the third platform 13, allowing two sides of the third platform 13 to be suspended. These two surfaces are used to position the bottom plate. One of these surfaces works with the rear support unit on the second platform 12 to limit the bottom and top of the rear side panel, preventing it from tilting and improving positioning accuracy. The other surface works with one of the clamping units to limit the bottom and top of the right side panel, preventing it from tilting and improving positioning accuracy. Then, the left side panel 72 is positioned using another clamping unit. Finally, the front side panel 71 and the top cover 73 are installed to complete the overall assembly of the mailbox.

[0025] The fuel tank assembly fixture in this embodiment uses a base 1, a rear support unit, and two clamping units to quickly and effectively position the left side plate 72, right side plate, bottom plate, and rear side plate of the tank. The positioning is accurate and the assembly efficiency is high. In addition, a small parts installation is designed for the marking template, which can be used to lay out and mark the side plates on the tank with small parts installed. This can avoid the problem of errors that are easy to make by manual marking and improve the marking efficiency and accuracy.

[0026] The clamping unit includes two side frames 3, the bottom of which is rotatably connected to the bottom of the support 2, and the support 2 is vertically fixed to the first platform 11 or the third platform 13.

[0027] The top of the support 2 is provided with a pin 4, which is inserted into a pin hole, and the pin hole is located in the side frame 3.

[0028] The top of the side frame 3 is provided with an abutment plate facing the box body. The abutment plate abuts against the left side plate 72 or the rear side plate of the box body. The abutment plate is provided with a clearance groove in the middle.

[0029] The rear support unit includes a back plate 6 and two rear frames 5. Both side frames 3 are vertically fixed to the second platform 12. The back plate 6 is fixed to the side of the rear frame 5 facing the rear side panel of the box, and the back plate 6 abuts against the rear side panel of the box.

[0030] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model shall fall within the scope of the technical solution of the present utility model.
