Abstract
The invention discloses a kind of piston of high power diesel engine and connecting rod assemble method.It includes the following steps: that 1. installing connecting rods 2. 3. 4. install piston head and be 5. inserted into piston pin fixed connecting rod by swivel link position to needed for assembling, installation upper ball cover, progress inside diameter measurement.The present invention overcomes existing assembly model, the manpower that when operation needs is more, and time-consuming, the problem of inconvenient benefit has redesigned a kind of piston and connecting rod assemble method, improves the speed of live actual assembled, convenience when assembly operation is improved, to promote machine assembly efficiency.
Description
Technical field
The present invention relates to high-power diesel engine technical fields, more particularly to a kind of high-power diesel engine upper piston and connecting rod
Assemble method.
Background technique
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 is expanded to generate the combustion gas of high temperature, high pressure using combustion gas as working medium in the cylinder, and piston is pushed to move reciprocatingly,
Make thermal energy mechanical energy, this reciprocating motion of piston becomes the rotary motion of crankshaft by crank link mechanism, drives
Jackshaft and propeller push ship to advance.Piston is the main component that thermal energy is become to mechanical energy, and connecting rod is then by piston
Move back and forth the rotary motion for becoming crankshaft.
It is single assembly model when current existing piston rod assembling, 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 when assembly operation, to promote complete machine together
Assembly efficiency.
Summary of the invention
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 assembly efficiency.
In order to achieve the above object of the invention, technical solution of the invention is as follows.
A kind of piston of high power diesel engine and connecting rod assemble method, comprising the following steps:
1. connecting rod is hung in mounting base, fall in wrist-pin end of connecting rod 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
It is mounted in connecting rod tip, measures aperture.After completing measurement, big-end bearing lid is dismantled；
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 low problem of packaging efficiency 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, assembly efficiency greatly improved.

Specific embodiment
We come in conjunction with attached drawing and specific case study on implementation to piston of high power diesel engine and connection rod set of the invention below
Dress method further describes in detail, 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, fall in wrist-pin end of connecting rod on the baffle 3 of mounting base 2；With taking
Buckle assembly 4 locks connecting rod 1, and it is fixed to connecting rod 1 that handle 5 is tightened in rotation；
Referring to Fig. 2, by the rotation of connecting rod 1 to connecting rod tip notch horizontal direction, it is 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.After completing measurement, big-end bearing lid 7 is dismantled.
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；It is inserted into piston pin 9, completes the group of piston 8 and connecting rod 1
Dress.
The present invention has comprehensively considered the convenience and safety of workshop assembly, reduces the difficulty of live actual installation,
The safety for improving live actual installation, improves assembly efficiency.
