Abstract

The invention provides a mechanical processing technique for a cylinder jacket. The mechanical processing technique comprises the following steps: rough machining, rough honing of an inner hole and finishing machining. The step of rough honing of the inner hole is moved after the step of rough machining and before the step of finishing machining, and is carried out after the step of finish boring or finish reaming, so that the grinding head in the rough honing step can be used for honing the inner hole of the cylinder jacket under lower expansion-contraction pressure, so as to achieve the purposes of removing the surplus of the surface of the inner hole of the cylinder jacket and modifying the shape error of the inner surface. The precision of the honed inner hole is high, the error is greatly reduced, so that the error of finish turning of the excircle or the supporting shoulder in the finishing machining step can be greatly reduced, the error superposition in the finishing machining step can be basically stopped at the beginning, therefore, the precision of the inner circle and the excircle of the cylinder jacket is improved, and the finally obtained cylinder jacket can meet the standards.

Description

A kind of cylinder liner mechanical processing technique
Technical field
The invention belongs to the Machining Technology field, relate to a kind of cylinder liner mechanical processing technique.
Background technology
Cylinder jacket is divided into wet type and dry type, and existing wet type and dry liner generally carry out the roughing operation earlier adding man-hour, and then carry out finishing step.The concrete processing technology of wet liner is: cut two ends, turning → heavy boring endoporus (or heavy boring endoporus → cut two ends, turning) → half finish turning cylindrical → right boring (or finish reaming) → finish turning supporting shoulder and water channel → cut supporting shoulder breadth degree → the cut upper and lower waistband of water sealed tank → rough honing endoporus → finish turning → microhoning endoporus.The concrete processing technology of dry liner is: cut two ends, turning → heavy boring endoporus (or heavy boring endoporus → cut two ends, turning) → half finish turning cylindrical → right boring (or finish reaming) → finish turning cylindrical → finish turning supporting shoulder breadth degree → rough honing endoporus → thick centreless grinding → microhoning → smart centreless grinding.
The something in common of wet type and dry liner is: when the processing endoporus, serve as the location benchmark with the cylinder jacket cylindrical; Turning or when shoulder supporting are the location benchmark with the cylinder cover inner hole.This process route that replaces repeatedly, processes the location benchmark each other, endoporus or cylindrical form error that initial roughing operation is processed, the endoporus after the roughing particularly, do not carrying out under the situation of honing, the error of endoporus is bigger, then causes the error of ensuing turning and car supporting shoulder to increase, and surface to be machined duplicates repeatedly, caused the form error of the inside and outside circle of cylinder jacket to be duplicated repeatedly and superpose, it is bad or overproof to form the final products form error.
Summary of the invention
The purpose of this invention is to provide a kind of cylinder liner mechanical processing technique that can obviously reduce error.
For achieving the above object, the present invention by the following technical solutions: a kind of cylinder liner mechanical processing technique, carry out the roughing operation earlier, carry out the rough honing endoporus then, carry out finishing step again.
Described cylinder jacket is a wet liner.
Described roughing operation is: cut turning behind the liner blank two ends, carry out the heavy boring endoporus again, or earlier to liner blank heavy boring endoporus, cut two ends, turning again; Carry out half finish turning cylindrical then, or finish ream.
Described finishing step is: first finish turning supporting shoulder and water channel, and then cut supporting shoulder breadth degree and cut water sealed tank, carry out upper and lower waistband of finish turning and microhoning endoporus at last.
Described cylinder jacket is a dry liner.
Described roughing operation is: cut turning behind the liner blank two ends, carry out the heavy boring endoporus again, or earlier to liner blank heavy boring endoporus, cut two ends, turning again; And then carry out half finish turning cylindrical, or finish ream.
Described finishing step is for carrying out the finish turning cylindrical earlier, and then carries out finish turning supporting shoulder breadth degree and thick centreless grinding, carries out microhoning and smart centreless grinding at last.
The present invention moves to the rough honing endoporus after the roughing operation, just before the finishing step, right boring or finish ream and carry out the rough honing endoporus after the operation again, make the endoporus of bistrique honing cylinder jacket under low harmomegathus pressure of rough honing operation, to reach the purpose of removing the cylinder jacket inner bore surface surplus and revising the inner surface configuration error, endoporus precision through rough honing is higher, error reduces greatly, what make that finishing step carries out is that the finish turning cylindrical of benchmark or the error of finish turning supporting shoulder also reduce greatly with the endoporus, basically cut off the error stack situation of finishing step from the source, thereby improved in the cylinder jacket, the precision of cylindrical makes final cylinder jacket meet standard.
