DETAILED DESCRIPTION

[0030] In order to more clearly illustrate the embodiments of the utility model or the technical solutions in the prior art, the specific implementation methods of the utility model will be described below with reference to the accompanying drawings. Obviously, the drawings described below are only some embodiments of the utility model. For ordinary technicians in this field, they can also be understood as further technical solutions without paying creative work. In some figures, components with the same structure or function are only schematically illustrated, or only one of them is marked. In this article, "one" not only means "only one", but also means "more than one", and "several" includes "two" and "more than two".

[0031] In this article, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in this utility model can be understood according to specific circumstances.

[0032] In addition, in the description of the present application, the terms "first", "second", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0033] Reference Figure 1~Figure 4 , which is the first embodiment of the utility model, proposes an oil pan with a positioning structure, including: the oil pan 1 has a mounting groove 110; the mounting plate 2 is arranged in the mounting groove 110; there are a plurality of positioning members 3, which are arranged outside the mounting groove 110, and the plurality of positioning members 3 together form a mounting space 310. After the mounting plate 2 enters the mounting space 310, the plurality of positioning members 3 abut against the side wall of the mounting plate 2, and the positioning members 3 are used to limit the movement of the mounting plate 2.

[0034] In this embodiment, the mounting plate 2 needs to be installed on the mounting groove 110, and the mounting plate 2 and the oil pan 1 are connected by welding. The positioning member 3 is arranged on one side of the mounting groove 110 and forms an installation space 310. When the mounting plate 2 is installed, the installation space 310 will limit the position of the mounting plate 2 to prevent the mounting plate 2 from being offset. Compared with the traditional positioning fixture, the positioning member 3 is integrally formed with the oil pan 1, which will not affect the normal use of the oil pan 1. Moreover, after a single oil pan 1 is installed once, it will not be repeatedly installed, and the problem of wear and tear caused by repeated use of the traditional positioning fixture will not occur, thereby improving the quality of the product. During welding, even if the welding collision is large, due to the presence of the positioning member 3, the mounting plate 2 will not be displaced, further improving the quality of welding and reducing the defective rate.

[0035] As a further technical solution, the mounting plate 2 has a chamfer 320 on one side close to the mounting groove 110 .

[0036] In this embodiment, the chamfer 320 on the mounting plate 2 enlarges the cross-sectional area of ​​the mounting space 310. The mounting plate 2 can enter the mounting space 310 and abut against the chamfer 320 without being too precisely positioned during installation. Subsequently, under the action of gravity, the mounting plate 2 will slide down along the chamfer 320 and enter the mounting groove 110, thereby fixing the mounting plate 2. The design of the chamfer 320 reduces the difficulty of installing the mounting plate 2 and increases the speed of installing the mounting plate 2.

[0037] As a further technical solution, it also includes: there are a plurality of support blocks 4 arranged on the oil pan 1, and after the mounting plate 2 enters the mounting groove 110, the support blocks 4 abut against the ground of the mounting plate 2, and the support blocks 4 are used to support the mounting plate 2.

[0038] In this embodiment, the support block 4 is used to support the bottom surface of the mounting plate 2 to prevent the mounting plate 2 from tilting due to incomplete bottom support during welding operations, thereby improving the neatness of the finished welding product and reducing the scrap rate.

[0039] As a further technical solution, the oil pan 1 has a plurality of screw holes 120 , and also includes: connecting bolts 5 detachably arranged on the screw holes 120 ; a clamping plate 6 is arranged on the connecting bolts 5 , and after the mounting plate 2 is installed, the clamping plate 6 abuts against the mounting plate 2 .

[0040] In this embodiment, the connecting bolt 5 is installed in the screw hole 120, and the mounting bolt is fixed with a clamping plate 6. By adjusting the mounting bolt, the clamping plate 6 will clamp the mounting plate 2. The mounting plate 2 is relatively small in size, which prevents the mounting plate 2 from being clamped by the clamping plate 6, causing the welding operation to be affected by the clamping plate 6, thereby slowing down the construction progress. At the same time, after the clamping plate 6 clamps the mounting plate 2, it will prevent the mounting plate 2 from being deformed when it is locally heated, thereby improving the quality of the mounting plate 2 after welding.

[0041] As a further technical solution, it also includes: there are several clamping rods 610, and the several clamping rods 610 jointly clamp the mounting plate 2; the two ends of the elastic member 620 are respectively arranged on the clamping rod 610 and the clamping plate 6. The elastic member 620 is used to provide a force to keep the clamping rod 610 away from the clamping plate 6.

[0042] In this embodiment, the clamping rod 610 is used to clamp the mounting plate 2. The elastic member 620 and the clamping rod 610 work together to ensure that the clamping rod 610 clamps the mounting plate 2. The use of the clamping rod 610 not only reduces the contact area with the mounting plate 2, but also reduces the limitation of the mounting rod on the welding operation, thereby ensuring the quality of welding.

[0043] As a further technical solution, it also includes: a sealing edge 130 is arranged on the oil pan 1, and the sealing edge 130 is located in the mounting groove 110. After the mounting plate 2 is installed, the sealing edge 130 abuts against the ground of the mounting plate 2.

[0044] In this embodiment, when the mounting plate 2 enters the mounting groove 110, the sealing edge 130 will abut against the top surface of the mounting plate 2 and perform a seal. The design of the sealing edge 130 can not only prevent the mounting plate 2 from being deviated after entering the mounting groove 110, but also prevent a large amount of oil from impacting the weld, thereby ensuring the quality of the weld and preventing the oil from being contaminated by impurities in the weld.

[0045] As a further technical solution, it also includes: there are a plurality of anti-skid patterns 140 arranged at the bottom of the oil pan 1 .

[0046] In this embodiment, the provision of the anti-slip pattern 140 not only facilitates the fixation of the oil pan 1 , but also enhances the strength of the oil pan 1 , thereby further ensuring the processing accuracy of the oil pan 1 .

[0047] It should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
