Description

Technical Field

[0001] This utility model relates to the field of oil production equipment technology, specifically to an assembly tooling for welding oil pumping unit connecting rod assemblies. Background Art

[0002] Beam pumping units, as the oldest and most widely used type of pumping unit, remain the main equipment for oilfield production, possessing numerous advantages such as simple structure, reliable performance, and widespread availability. However, the types of beam pumping units on the market vary, often requiring different dimensions for the connecting rods to be welded.

[0003] The old method of welding connecting rods involved manually assembling and welding them according to drawings, after determining the positions by marking lines. This method had many problems, such as:

[0004] ① The scribing process requires confirming the position of each part according to the dimensions in the drawing and calculating the various dimensional lines that need to be scribed. Since the overall length of the connecting rod is relatively long, the scribing dimension error is large, and the dimensional tolerances such as symmetry are easy to exceed the tolerance. Moreover, each connecting rod needs to be scribed, which not only poses a high quality risk but is also time-consuming and labor-intensive.

[0005] ② The assembly process often requires 2-3 welders and involves multiple flips of the connecting rod, repeated marking, assembly, and welding, resulting in low efficiency and high labor costs.

[0006] Considering factors such as cost, product quality, efficiency, and output, manual marking is not suitable for batch welding of connecting rod assemblies. There is an urgent need for a universal tooling that can be applied to connecting rod assemblies of various models of beam pumping units to reduce labor costs and improve product quality and production efficiency. Utility Model Content

[0007] In view of the shortcomings of the prior art, the purpose of this utility model is to provide an assembly tooling for welding the connecting rod assembly of an oil pumping unit, which can solve the above technical problems.

[0008] To achieve the above objectives, this utility model provides the following technical solution:

[0009] An assembly fixture for welding a connecting rod assembly of an oil pumping unit includes a base. Multiple upper connector support plates are provided on one side of the top of the base. One of the upper connector support plates has an upper connector support seat on its top. The upper connector support seat has a U-shaped structure, and upper connector caps are provided on the top of both vertical sides of the upper connector support seat. The upper connector caps are connected to the upper connector support seat by bolts. A lower connector support plate is provided on the other side of the top of the base. A lower connector support seat is provided on the top of the lower connector support plate, and a lower connector cap is provided on the top of the lower connector support seat. The lower connector caps are connected to the lower connector support seat by bolts. Several main beams are provided between the upper and lower connector support plates, and the main beams are fixedly connected to the base.

[0010] Preferably, multiple upper connector support plates are welded side by side to the base, and the upper connector support seat is connected to the upper connector support plate by bolts.

[0011] Preferably, the lower connector support plate is bolted to the base.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. By using the tooling of this utility model to replace the scribing assembly, single-person rapid welding can be achieved, reducing assembly time and improving product quality and production efficiency.

[0014] 2. The tooling of this utility model is applicable to different models of products and is easy to modify later, which reduces the manufacturing cost of the tooling. Attached Figure Description

[0020] The invention will now be described in detail with reference to the accompanying drawings, by way of example. Obviously, the described embodiments are only some embodiments of the invention, and not all embodiments. Example

[0021] like Figures 1 to 2 As shown, this utility model discloses an assembly fixture for welding a pumping unit connecting rod assembly, including a base 1. Two upper connector support plates 2 are welded side by side to one side of the top of the base 1. One of the upper connector support plates 2 is provided with an upper connector support seat 3 on its top, and the upper connector support seat 3 is connected to the upper connector support plate 2 by bolts. The upper connector support seat 3 adopts a U-shaped structure, and upper connector pressure caps 4 are provided on the top of each of the two vertical sides of the upper connector support seat 3. The upper connector pressure caps 4 are connected to the upper connector support seat 3 by bolts. A lower connector support plate 5 is provided on the other side of the top of the base 1. The lower connector support plate 5 is connected to the base 1 by bolts. A lower connector support seat 6 is provided on the top of the lower connector support plate 5. A lower connector pressure cap 7 is provided on the top of the lower connector support seat 6. The lower connector pressure cap 7 is connected to the lower connector support seat 6 by bolts. Two main beam supports 8 are provided between the upper connector support plate 2 and the lower connector support plate 5. Both main beam supports 8 are fixedly connected to the base 1.

[0022] In practical applications, adjust the positions of the upper connector support 3 and the upper connector cap 4 according to the different connecting rod assembly dimensions, and replace the lower connector support plate 5, lower connector support 6, and lower connector cap 7 with the corresponding dimensions; fix the connecting rod pin with the upper connector cap 4, and fix the upper connector with the upper connector support 3; use the main beam support 8 to support the main beam of the connecting rod, ensuring the main beam is horizontal and facilitating welding without multiple flipping; restrict the position of the lower connector with the lower connector support 6, indirectly limiting the welding length of the main beam; use the lower connector cap 7 to fix the lower connector, ensuring the symmetry requirements of the connecting rod assembly. After adjusting the connecting rod assembly, spot weld it in place, check all dimensions, and perform welding after passing inspection; after welding is completed, remove the upper connector cap 4 and the lower connector cap 7, and lift the connecting rod assembly from the tooling.

[0023] This utility model has the following advantages:

[0024] ① The upper connector support base 3 is fixed with bolts, and multiple upper connector support plates 2 are welded on the base 1. By changing the installation position, it can be used to accommodate connecting rods of different lengths. If modification is required, only the upper connector support plate 2 needs to be welded to the corresponding position of the connecting rod tooling base 1. Modification is simple, disassembly and assembly are convenient, and tooling costs are saved.

[0025] ② The lower connector support plate 5 is bolted to the base 1, and the lower connector is positioned by the outer circle to ensure the center distance and form and position tolerance of the connecting rod; and the lower connector support plate 5, lower connector support seat 6 and lower connector pressure cover 7 can be replaced according to different models of connecting rods. When modifying the tooling, only the lower connector support plate 5, lower connector support seat 6 and lower connector pressure cover 7 with different diameters and heights need to be designed, which is simple to modify, convenient to replace and saves costs.

[0026] ③ By positioning both ends of the tooling simultaneously, the old segmented marking assembly is replaced, reducing the impact of connecting rod welding deformation and ensuring product quality.

[0027] ④ It saves 0.5-1 hour of time and only requires one welder to complete the task, thus saving labor costs.

[0028] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and application concept of the present utility model, should be included within the protection scope of the present utility model.
