Abstract
The invention relates to a customized high-power diesel plunger and barrel assembly. The customized high-power diesel plunger and barrel assembly comprises a plunger bushing; a mounting hole is formed in the middle of the plunger bushing; a plunger matched with the mounting hole is mounted in the mounting hole; the working outer circular surface of the plunger is in clearance fit with the inner surface of the mounting hole of the plunger bushing; the gap between the working outer circular surface of the plunger and the inner surface of the mounting hole of the plunger bushing is 2-3 microns. The customized high-power diesel plunger and barrel assembly is compact and reasonable in structure, and is customized by use of a numerical control grinder; as a result, one-person multiple-machine operations are realized, the labor cost is reduced and the product quality is improved.
Description
Technical field
The present invention relates to plunger coupled parts technical field, especially a kind of Custom Prosthesis high-power diesel plunger coupled parts.
Background technique
The enforcement of national marine policy, impels Marine High-power Diesel Engine and generator set demand to increase, the monoblock pump pump oil parts matched and plunger coupled parts.During work, plunger is high speed to-and-fro motion in plunger bushing, and the fuel oil from low-pressure cavity is compressed, and improves pressure, provides and sprays and burning.In prior art, comparatively greatly, working diameter has φ 16 to φ 55 not for these monoblock pump pump oil parts and plunger coupled parts boundary dimension, and adopt plain grinding processing, processing difficulties, processing cost is high.
Summary of the invention
The applicant, for the shortcoming in above-mentioned existing production technology, provides a kind of Custom Prosthesis high-power diesel plunger coupled parts rational in infrastructure, thus adopts numerical control grinding device customizing, realizes people's multi-machine operation, reduction recruitment cost, Improving The Quality of Products.
The technical solution adopted in the present invention is as follows:
A kind of Custom Prosthesis high-power diesel plunger coupled parts, comprise plunger bushing, mounting hole is had in the middle part of described plunger bushing, the plunger be mated is installed in described mounting hole, adopt Spielpassung between the work outer round surface of described plunger and plunger bushing mounting hole internal surface, the gap between the work outer round surface of described plunger and plunger bushing mounting hole internal surface is 2um-3um.
Further improvement as technique scheme:
The circularity of the work outer round surface of described plunger is 0.5um.
The flat shape degree of the work outer round surface of described plunger is 0.6um.
The straightness accuracy of the work outer round surface of described plunger is 1um.
The roughness Rz of the work outer round surface of described plunger is 0.63.
The circularity of described plunger bushing mounting hole is 0.5um.
The surperficial parallelism of described plunger bushing mounting hole is 0.8um.
The surperficial straightness accuracy of described plunger bushing mounting hole is 1um.
The surface roughness Rz of described plunger bushing mounting hole is 0.32.
Beneficial effect of the present invention is as follows:
Compact structure of the present invention, rationally, by adopting numerical control grinding device customizing, realize people's multi-machine operation, reduction recruitment cost, Improving The Quality of Products.
