Technical Field
The invention belongs to the technical field of petroleum machinery equipment, and relates to a processing method of a plunger pump connecting rod assembly.
Background
The market demand of the plunger pump is vigorous day by day, but the plunger pump has a complex internal structure and high assembly precision requirement, so that the manufacturability of individual parts is poor and the processing is difficult, particularly the processing of a connecting rod assembly of the plunger pump. Although the traditional processing mode can ensure the processing precision requirement of each part in the connecting rod assembly, after the parts are combined, the overall shape and position requirement of the connecting rod assembly in the assembling process of the plunger pump cannot be ensured, and the adjustment cannot be realized.
Disclosure of Invention
The invention aims to provide a processing method of a plunger pump connecting rod assembly, which solves the problem that the overall shape and position requirements of the connecting rod assembly in the plunger pump assembling process cannot be ensured in the prior art.
The technical scheme adopted by the invention is that the processing method of the plunger pump connecting rod assembly is implemented according to the following steps:
step 1, semi-finish machining a connecting rod;
and 3, performing finish machining on the connecting rod assembly to finish machining of the connecting rod assembly.
The invention is also characterized in that:
step 1 is specifically carried out as follows: and (2) processing a semicircular groove at one end of the connecting rod, wherein the groove penetrates through the connecting rod, the diameter of the groove is matched with that of the pin shaft in the step (2), and a large hole is processed on the connecting rod (1) and is positioned at the other end close to the connecting rod.
And (3) finishing the semicircular groove in the step (1).
The macropores in step 1 are semi-finished.
The invention has the beneficial effects that: the processing method of the plunger pump connecting rod assembly solves the problems that the overall shape and position requirements of the connecting rod assembly in the plunger pump assembling process cannot be guaranteed, parts in the connecting rod assembly are respectively processed and then assembled, and the assembly error is generated in the prior art, and is simple and easy to implement and high in processing precision; the influence on the form and position error of the connecting rod assembly after the connecting rod small-end pin shaft is assembled with the connecting rod is eliminated; the eccentric wear to the guide plate after the crosshead assembly and the connecting rod assembly are assembled is reduced, and the hidden quality trouble of pulling damage to the guide plate of the plunger pump is reduced.
