The main structural components of a pumping unit include: the walking beam section, the support section, the reducer section, and the power distribution section. The walking beam section includes the donkey head, walking beam, crossbeam, tail beam, connecting rod, and balance plate.

Detailed Implementation
[0023] 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
[0024] like Figures 1 to 3 As shown, this utility model discloses an adjustable welding fixture for a pumping unit connecting rod, including a main support beam 1. A slide rail 2 is fixedly connected to one side of the top of the main support beam 1. A handle 3 is provided at one end of the slide rail 2. A rolling screw 4 is connected to the handle 3. A connecting rod upper joint support 5 is connected to the rolling screw 4. The connecting rod upper joint support 5 is slidably connected to the slide rail 2. The connecting rod upper joint support 5 includes an upper support base plate 51. Both ends of the top surface of the upper support base plate 51 are provided with upright plates 52. Each of the two upright plates 52 has a pressure cap 53 bolted to its top. Each of the two upright plates 52 has a positioning center plate 8 on its opposite side. The two positioning center plates 8 are symmetrically arranged along the central axis of the upper support base plate 51. A reinforcing plate 54 is also provided between the two upright plates 52. The rolling screw 4 is threadedly connected to the threaded hole in the middle of the reinforcing plate 54. By rotating the handle 3, the rolling screw 4 is driven to rotate, thereby adjusting the position of the joint support 5 on the connecting rod so as to be suitable for welding different models of connecting rod assemblies.
[0025] like Figure 1 and Figure 4 As shown, a lower connector support 6 for a connecting rod is provided on the other side of the top of the main support beam 1. The lower connector support 6 for the connecting rod is fixedly connected to the main support beam 1. The lower connector support 6 for the connecting rod includes a lower support base plate 61. A support platform 62 is provided at the center of the top surface of the lower support base plate 61. A pressure plate 63 is provided on the top of the support platform 62. Positioning center plates 8 are provided on two opposite surfaces of the support platform 62. The two positioning center plates 8 are symmetrically arranged along the central axis of the support platform 62.

Then, the upper connector support 5 of the connecting rod is installed on the slide rail 2 of the main support beam 1. Next, the rolling screw 4 and the handle 3 are installed. According to the center distance requirements of the connecting rod, the distance between the center of the upper connector support 5 and the center of the lower connector support 6 of the connecting rod is adjusted by rotating the rolling screw 4 through the handle 3. When measuring the distance, the positions of the positioning center plates 8 on both sides of the lower connector support 6 and the upper connector support 5 of the connecting rod need to be measured simultaneously to ensure that the distance measured on both sides is consistent and meets the center distance requirements of the drawing. Finally, the nut on the upper connector support 5 is fastened to the T-bolt on the slide rail 2 of the main support beam 1, and the adjustment of the connecting rod tooling is completed.
[0028] The connecting rod welding assembly operation is as follows: 1) First, remove the pressure cap 53 on the upper connector support 5 of the connecting rod, insert the connecting rod pin, and install the connecting rod pin symmetrically on both sides, then fix the upper pressure cap 53; 2) Assemble the connecting rod upper connector plate and the connecting rod pin together, installing both sides; 3) Install the connecting rod lower connector plate above the connecting rod lower connector support 6; 4) Install the intermediate support 7; 5) Place the connecting rod main beam I-beam on the intermediate support 7.
