Abstract

The invention discloses a kind of piston of high power diesel engine and connecting rod assemble method.It includes the following steps:1. 2. installing connecting rods fix connecting rod 3. position needed for swivel link to assembling, upper ball cover is installed, 4. progress inside diameter measurement installs piston head and is 5. inserted into piston pin.The present invention overcomes existing assembly model, the manpower that when operation needs is more, and time-consuming, the problem of inconvenient profit, has redesigned a kind of piston and connecting rod assemble method, improves the speed of live actual assembled, convenience during assembly operation is improved, so as to promote final assembly efficiency.

Description

A kind of piston of high power diesel engine and connecting rod assemble method
Technical field
The present invention relates to high-power diesel engine technical field, more particularly to a kind of high-power diesel engine upper piston and connecting rod Assemble method.
Background technology
The basic functional principle of diesel engine is that fuel is made to burn in the cylinder of engine, and the chemical energy of fuel is changed into Thermal energy so as to generate the combustion gas of high temperature, high pressure, is expanded in the cylinder using combustion gas as working medium, and piston is pushed to move reciprocatingly, Make thermal energy for mechanical energy, this reciprocating motion of piston is become the rotary motion of bent axle by toggle, driven Jackshaft and propeller push ship to advance.Piston is the critical piece that thermal energy is become to mechanical energy, and connecting rod is then by piston Move back and forth the rotary motion for becoming bent axle.
It is single assembly model during existing piston rod assembling at present, the manpower that when operation needs is more, and time-consuming, behaviour Make not convenient.To solve the above problems, a kind of piston and connecting rod assemble method need to be redesigned, become ten by single assembly model A one group assembly model, the speed of the live actual assembled of raising improve convenience during assembly operation, so as to promote complete machine together Efficiency of assembling.
Invention content
It is an object of the invention to solve the problems, such as piston of high power diesel engine and connecting rod assembling inefficiency, one kind is provided New piston of high power diesel engine and connecting rod assemble method.This method can simplify the assembling procedure of connecting rod and piston, improve scene The accuracy of actual assembled improves efficiency of assembling.
In order to reach foregoing invention purpose, technical solution of the invention is as follows.
A kind of piston of high power diesel engine and connecting rod assemble method, include the following steps:
1. connecting rod is hung in mounting base, wrist-pin end of connecting rod is made to fall on the baffle of mounting base;
2. being close to bar with hasp lock, rotation is tightened handle to connecting rod and is fixed;
3. rotating connecting rod to connecting rod tip notch horizontal direction, fixed with positioning pin, then by big-end bearing lid In connecting rod tip, aperture is measured.It completes after measuring, dismantles big-end bearing lid;
4. extracting positioning pin, connecting rod is rotated into the position to wrist-pin end of connecting rod upward;
5. piston head is placed on the baffle of mounting base, positioned by the positioning convex platform on baffle;
6. being inserted into piston pin, the assembling of piston and connecting rod is completed.
Compared with prior art, the beneficial effects of the present invention are the present invention solves piston of high power diesel engine connecting rod The problem of packaging efficiency is low provides a kind of new piston of high power diesel engine and connecting rod assemble method, simplify connecting rod and The assembling procedure of piston improves the accuracy of live actual assembled, efficiency of assembling greatly improved.

Fig. 2 is the installation diagram that big-end bearing lid is mounted on connecting rod tip.
Fig. 3 is piston and the installation diagram of connecting rod assembling.
Figure label:1- connecting rods;2- mounting bases, 3- baffles, 4- catch assemblies, 5- tighten handle;6- positioning pins, 7- connect Bar big-end bearing lid, 8- pistons.9- piston pins.
Specific embodiment
We carry out the piston of high power diesel engine and connection rod set to the present invention with reference to attached drawing and specific case study on implementation below Dress method is further elaborated, but is not intended to limit the protection scope of the present invention.
Embodiment 1
In embodiment, during piston of high power diesel engine and connecting rod assembling, it is related to mounting base 2, positioning pin 6, hasp Component 4 and tighten handle 5.2 top of mounting base is equipped with baffle 3, and baffle 3 is equipped with positioning convex platform;Catch assembly 4 is by tightening Handle 5 is locked.
Referring to Fig. 1, connecting rod 1 is hung in mounting base 2, wrist-pin end of connecting rod is made to fall on the baffle 3 of mounting base 2;With taking Buckle assembly 4 locks connecting rod 1, and rotation is tightened handle 5 to connecting rod 1 and fixed;
Referring to Fig. 2, rotating connecting rod 1 to connecting rod tip notch horizontal direction, fixed with positioning pin 6.Then by connecting rod Big-end bearing lid 7 is mounted in 1 big end of connecting rod, measures aperture.It completes after measuring, dismounting big-end bearing lid 7.
Referring to Fig. 3, extracting positioning pin, connecting rod 1 is rotated into the position to wrist-pin end of connecting rod upward;Piston 8 is placed in On the baffle 3 for filling bottom plate 2, positioned by baffle 3 positioning convex platform;Piston pin 9 is inserted into, completes the group of piston 8 and connecting rod 1 Dress.
The present invention has considered convenience and the safety of workshop assembling, reduces the difficulty of live actual installation, The safety of live actual installation is improved, improves efficiency of assembling.
