Abstract
The utility model relates to a structure of the powder metallurgical connecting rod for a compressor, which comprises a connecting rod body formed by pressing metal powder, a connecting rod shaft hole formed on the connecting rod body, and a connecting rod joint. The structure is characterized in that the connecting rod body and the connecting rod joint adopt a split-type structure; a semicircular shaft hole is formed at the end part of the connecting rod body, and an annular rabbet is formed on the outer circumference of the semicircular shaft hole; a semicircular shaft hole matched with the shaft hole of the connecting rod body is formed on the connecting rod joint, and an annular boss corresponding to the rabbet on the connecting rod body is formed on the outer circumference of the semicircular shaft hole and inserted into the rabbet; connection holes are correspondingly formed on two sides of either the connecting rod body or the connecting rod joint; and connecting bolts are mounted in the connection holes. When the connecting rod adopting the structure is used, only two parts are required to be connected through the bolts, so that the utility model has the advantages of simple structure, convenient use, long service life, reduced rejection ratio and production cost, improved operating efficiency, etc.
Description
Technical field
The utility model belongs to powder metallurgical technology, particularly relates to a kind of compressor powder metallurgy bar linkage structure.
Background technique
At present, because the restriction of throughput, what connecting rod was produced all is the primary blank part, and existing connecting rod adopts an individual configurations, is processed with small one and large one axis hole at the two ends of main body.The connecting rod of this kind structure need carry out could using after the follow-up processing, course of working comprises beats preset holes, to two pre-axis placing holes process, operation such as rounding, therefore need to carry out the processing of a large amount of place to go materials before use, the waste of material that causes like this, increased cost of production again, and a large amount of following process prolongs the manufacture cycle, reduced manufacturing efficiency.
Summary of the invention
The utility model provides a kind of simple in structure, easy to use, rate of reducing the number of rejects and seconds and cost of production for solving the technical problem that exists in the known technology, and has improved a kind of compressor powder metallurgy bar linkage structure of working efficiency.
The technological scheme that the utility model is taked for the technical problem that exists in the solution known technology is:
A kind of compressor powder metallurgy bar linkage structure, comprise the con-rod only that forms by the metallic dust compacting, con-rod only is provided with the connecting rod axis hole, linkage connector, it is characterized in that: described con-rod only and linkage connector adopt split-type structural, be shaped on semicircle axis hole in the end of con-rod only, be provided with annular stopper at the excircle of semicircle axis hole; Described linkage connector is provided with the semicircle axis hole that is complementary with the con-rod only axis hole, be provided with and the corresponding annular boss of seam on the con-rod only at the excircle of semicircle axis hole, this annular boss is inserted in the seam, correspondence is provided with attachment hole in the both sides of con-rod only and linkage connector, and connecting bolt is installed in attachment hole.
Advantage and the good effect that the utlity model has are: because the utility model is adopting technique scheme, be that described con-rod only and linkage connector adopt split-type structural, be shaped on semicircle axis hole respectively at con-rod only and linkage connector, con-rod only and linkage connector are located by seam, and connect by connecting bolt, take the connecting rod of said structure only to need in use two parts are got final product with the bolt connection, therefore the utlity model has simple in structure, easy to use, life-span is long, the rate of reducing the number of rejects and seconds and cost of production, and improved advantages such as working efficiency.
