Abstract
The utility model provides a connecting rod positioning structure of an engine. Two small locating pins are arranged beside a connecting rod connecting screw bolt, and the positioning of a connecting rod cover and the connecting rod body is realized by the two locating pins. The positioning structure overcomes the defect of the positioning of a high precision screw bolt and a sleeve barrel. The utility model has the advantages of simple structure, easy fabrication, reduced precision requirement to the connecting rod screw bolt, reduced processing cost and reduced weight of the big end of the connecting rod.
Description
Technical field
The utility model belongs to technical field of engines, is specifically related to a kind of connecting rod cap of engine and the location structure of gonnecting rod body.
Background technology
The location levels of precision of engine connecting rod structure is concerning the recovery degree of big end, directly influences the stationarity of circularity, cylindricity and the engine operation of major part.Being positioned with of general connecting rod cap and connecting rod by high precision screw bolt location (no nut), bolt shank location (nut is arranged), the three kinds of modes in sleeve location, but the above two are to the required precision height of bolt, and particularly bolt cost under the present manufacturing technology situation of China of high precision screw location is higher.Therefore this location high precision screw bolt is by import mostly, causes the engine cost to increase.The latter is press-fitted the short sleeve of a very big rigidity in each bolt hole of connecting rod, to being press-fitted sleeve required precision height, making required cost also increases thereupon and cause the connecting rod volume to increase, and quality increases.Particularly the centrifugal force of major part makes the connecting-rod bearing, and the base bearing load increases, the wearing and tearing aggravation.
Summary of the invention
The utility model is at the deficiency of available engine connecting-rod bolts location structure, a kind of link lever positioning structure of engine is provided, improves high accuracy bolt and sleeve location defect, the location of realizing connecting rod cap and connecting rod with alignment pin, reduce the requirement on machining accuracy of bolt, cut down finished cost.
This link lever positioning structure is by designing two little alignment pins on connecting rod connecting bolt side, by these two location that alignment pin is realized connecting rod cap and gonnecting rod body.This location structure is simple, and is easy to process; Can reduce required precision, alleviate the weight of big end connecting-rod bolts.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the structural representation after the utility model has assembled the connecting rod connecting bolt.
The specific embodiment
Referring to Fig. 1,1 is big end among the figure, the 2nd, and bolt hole, the 3rd, the connecting rod connecting bolt is provided with two little alignment pins 4 respectively on bolt hole 2 sides, and the connecting rod assembling positions by these two alignment pins 4, guarantees recovery accuracy.
Claims (1)
1, a kind of link lever positioning structure of engine, it has big end, has bolt hole on big end, and assembling connecting rod connecting bolt is characterized in that: be provided with two little alignment pins on connecting rod connecting bolt side.
