Example Embodiment

[0016] The application will be described in detail below in conjunction with the accompanying drawings.

[0017] A fracturing pump connecting rod processing datum marking method, which includes the following steps:

[0018] S1, placing the connecting rod body 1 on a plane, the connecting rod body 1 is an integrally formed steel casting, see figure 1 and figure 2 , the connecting rod body 1 includes a shaft 2 and a connecting rod big end 3 and a connecting rod small end 4 connected at both ends of the shaft, the transition section where the connecting rod small end 4 is connected to the shaft 2 is provided with a raised transition circle corner 5. Measure the first flatness of the plane where the shaft 2 is located. If the first flatness is 1 mm or less, proceed to the next step. If the first flatness is > 1 mm, add the surface of the shaft to ensure that the first flatness is 1 mm. and below.

[0019] S2, align the plane where the rod body 2 is located, and measure the se...

Abstract

The invention discloses a fracturing pump connecting rod machining datum marking method which comprises the following steps that S1, a connecting rod body is placed on a plane, the first flatness of the plane where a rod body is located is measured, and it is guaranteed that the first flatness is 1 mm or below by machining the surface of the rod body; s2, the plane where the rod body is located is aligned, the second flatness of the area, except the coating, of the top face of the large end of the connecting rod is measured, the area, except the coating, of the top face of the large end of the connecting rod is machined, and it is guaranteed that the second flatness is 2 mm or below; and S3, the position, 10 mm close to the rod body, of a transition circular bead where the rod body is connected with the small end of the connecting rod serves as the starting position, a center line is drawn in the vertical direction according to the design requirement of a connecting rod body, the plane where the rod body is located and the area, except the coating, of the top face of the large end of the connecting rod serve as the follow-up alignment reference, and the center line serves as the follow-up machining reference. Smooth manufacturing of the fracturing pump connecting rod can be guaranteed, the rejection rate is reduced, and the manufacturing cost is saved.

Description

technical field [0001] The invention relates to the technical field of mechanical processing of connecting rods, in particular to a method for marking a standard for processing connecting rods of fracturing pumps. Background technique [0002] The fracturing pump is an important equipment for fracturing, acidizing operations and increasing oil and gas production in the oil field. It is in a complex mechanical environment such as heavy load and variable load. Its movement and the rationality of the load directly affect the working performance of the fracturing pump. The rod is the moving part that transmits power at the force end of the fracturing pump. During work, it is subjected to alternating loads such as tension, compression and bending, and the pulsation of the fluid in the pump. Therefore, the strength of the connecting rod must meet the requirements during processing. [0003] In the actual processing process, the tolerance of the non-machined surface contour of the ...
