CN102950419A - Precise basis type production processing flow for engine connecting rod - Google Patents

Abstract

The invention discloses a precise reference type production processing flow for an engine connecting rod. The production processing flow comprises the following steps of firstly, carrying out the first phase of processing before cutting of a connecting rod body and a cover, respectively carrying out blank inspection, magnetic particle inspection and rough drilling of a small-end hole, and preparing for the processing of upper and lower end surfaces, the small-end hole, two planes at bolt hole ends, an outer surface of a large-end hole, and the like in the precise basis way; then, carrying out processing after cutting of the connecting rod body and the cover, roughening the large-end hole, except for precise referencebasis, and preparing for the roughening of the bolt hole and the combining surface, and the processing of a bearing counterbored groove; and carrying out processing after cutting of the connecting rod body and the cover, and sequentially carrying out the finishing of the large-end hole after the assembly of the connecting rod, the finishing of the upper and lower end surfaces, and the finishing of the large-end hole and the small-end hole. The production processing flow has the beneficial effects that the speed of the linear movement can be smoothly adjusted, the running precision of the machine is favorably improved, the service life of the machine is prolonged, the arrangement is conveniently and flexibly realized according to requirements, the operation controllability is improved, and the labor strength is reduced.

Description

A kind of smart benchmark mode work flow for engine link

Technical field

The present invention relates to a kind of processing method, relate in particular to a kind of smart benchmark mode work flow for engine link.

Background technology

Hydraulic technique is one of key technology that realizes modernized transmission and control.Hydraulicdriven various element because lightweight, volume is little, can arrange easily and flexibly as required; realize conveniently, easily rectilinear motion, can realize large-scale stepless speed regulation, automatically realize overload protection in conjunction with state-of-the-art technology automaticity height and manipulation control, but adopt mineral oil as working media relative motion face lubricating by oneself, long service life.In recent years, hydropneumatics faces the competition with machine driving and Electrified Transmission, has adopted automatically controlled servo-drive system replacement or part to replace hydraulic drive such as Digit Control Machine Tool, middle-size and small-size molding machine; Its main cause is that hydraulic technique exists the shortcomings such as seepage, maintainability be poor; For this reason, must give full play to the advantage of hydropneumatics, attention and electronic technology combine, constantly enlarge application, reduce simultaneously energy consumption, raise the efficiency, adapt to the environmental protection demand, improve reliability, these all are the targets that hydropneumatics keeps punching, and also are the keys whether the hydropneumatic product is participated in market competition and won victory.But the hydraulic system assembly of existing this product exists a lot of problems from method of operating, working method, numerous and diverse different angles such as structure, and this causes work poor efficiency, heavier, the high expensive of weight of equipment.

Summary of the invention

The purpose of this invention is to provide and a kind ofly be conducive to convenient processing and manufacture, can make the steadily easily speed governing of its rectilinear motion, can enhance productivity, be convenient to safeguard, possess the auxiliary smart benchmark mode work flow that is used for engine link that improves the equipment operation ability, to solve many deficiencies of prior art.

Purpose of the present invention is come specific implementation by the following technical programs:

A kind of smart benchmark mode work flow for engine link mainly is comprised of following:

⑴ at first, the gonnecting rod body and the lid that carry out first stage cut processing before, carry out successively blank inspection, magnetic powder inspection, slightly bore the mode in microcephaly hole, smart benchmark is carried out the steps such as upper/lower terminal face, microcephaly hole, two bolt hole transverse planes and big end hole lateral surface and prepare;

⑵ carry out the processing after gonnecting rod body and lid cut then, and the big end hole roughing processing except smart benchmark is prepared as the roughing of bolt hole and faying face and the processing of bearing shell fore shaft groove;

⑶ last, carries out gonnecting rod body and cover processing behind the dress, carries out successively connecting rod and attach together the fine finishining of rear big end hole, the up and down fine finishining of both ends of the surface and the fine finishining in concentric reducer hole.

The beneficial effect of the smart benchmark mode work flow for engine link of the present invention is: be conducive to convenient processing and manufacture, can make steadily easily speed governing of rectilinear motion, be conducive to improve the machine movement precision, can increase the service life; Simultaneously, be conducive to arrange easily and flexibly as required, can improve the operation controllability, reduce labour intensity.

The specific embodiment

The described smart benchmark mode work flow for engine link of the embodiment of the invention, its key step comprises:

⑴ at first, the gonnecting rod body and the lid that carry out first stage cut processing before, carry out successively blank inspection, magnetic powder inspection, slightly bore the mode in microcephaly hole, smart benchmark is carried out the steps such as upper/lower terminal face, microcephaly hole, two bolt hole transverse planes and big end hole lateral surface and prepare;

⑵ carry out the processing after gonnecting rod body and lid cut then, and the big end hole roughing processing except smart benchmark is prepared as the roughing of bolt hole and faying face and the processing of bearing shell fore shaft groove;

⑶ last, carries out gonnecting rod body and cover processing behind the dress, carries out successively connecting rod and attach together the fine finishining of rear big end hole, the up and down fine finishining of both ends of the surface and the fine finishining in concentric reducer hole.
