Description
Technical field
The present invention relates to the assembly techniques of diesel engine, and in particular to one kind is used for diesel engine crank pin bearing Gai Yulian
The setting tool and method of bar dismounting, belong to diesel engine manufacturing technology field.
Background technique
The important component that connecting rod is transmitted as marine diesel oil machine host power, the upper end connect crosshead, and lower end connection is bent
Handle pin.In host operational process, connecting rod is connected piston and crosshead with crankshaft, will act at the gas pressure on piston
Power and inertia force pass to crankshaft, and the reciprocating motion of piston is transformed into the rotary motion of crankshaft.
Connecting rod is located at the machine frame inside of host, and crankshaft is located at the base inner of host, passes through crank between connecting rod and crankshaft
Pin bearing is connected with each other, which is connect with crank pin bearing lid pairing by the shaft of connecting rod one end and formed.Work as host
Rack and base when being split or being assembled, it is necessary to crank pin bearing is dismounted.Needing in disassembly process first will be bent
Crankpin bearing cap then is disengaged or is spliced to the top dead center position of each cylinder by reel vehicle.Due to the crankpin bearing cap
Installation be displaced larger (from base oil sump to the top dead centre of each cylinder crankshaft), and apart from the key components and parts such as crankshaft journal compared with
Closely, and connecting rod and crankshaft are all in the inside of host, and whole operations carry out in machine, therefore the crank pin bearing lid
Dismounting process process have the characteristics that time-consuming length, require it is tight.
Summary of the invention
The technical problem to be solved by the present invention is to, when breaking through existing frame of marine diesel engine rack division, crank pin
The difficult technical bottleneck of lid dismounting is held, a kind of efficient quick is provided and the safe diesel engine crank pin bearing lid that is used for is torn open with connecting rod
The setting tool and method of dress had both guaranteed the connection of marine diesel crank pin bearing lid and connecting rod, lived after realizing host assembly
The kinetic energy transmitting that plug is carried out to crankshaft by connecting rod, and improve labor efficiency taking into account, reinforce safe operation, reduction input cost
While, guarantee the precision of technique.
It is as follows that the present invention solves the technical solution that its technical problem is taken:
A kind of setting tool for diesel engine crank pin bearing lid and connecting rod dismounting, the two sides of the crank pin bearing lid

As a further improvement, the both sides of the positioning plate are respectively provided with a cylindrical protrusions, the cylindrical protrusions with
The arc-shaped outer surface of the crank pin bearing lid is bonded.
As a further improvement, being also welded with two nuts for placing connection bolt on the positioning plate.
As a further improvement, the positioning plate with a thickness of 10~12mm.
As a further improvement, the size of the positioning plate according to the distribution of the lifting eye of the crank pin bearing lid and
Size is determined.
As a further improvement, the limited block is according to the internal arm size of crank-pin, dial scale in the diesel engine
Very little and circular arc thickness is made.
Another technical solution of the invention are as follows:
A method of the diesel engine crank pin bearing lid and connecting rod realized using above-mentioned setting tool are dismounted, by described
The crank pin bearing lid is completely fixed on the crankshaft without any displacement by setting tool, as crankshaft jiggering comes
To the optimum assembling position spliced with the connecting rod, thus simplify in whole installation process to neutralization operation.
As a further improvement, the method that the crank pin bearing lid is installed with connecting rod includes the following steps:
1) by the crank-pin jiggering for the corresponding crankshaft of cylinder for needing to install crank pin bearing lid to lower dead center, and by institute
It states on the terrace that crank pin bearing lid is flat on outside machine, the positioning plate of the setting tool is then installed on the crank pin
It holds on the two sides of lid；
2) the crank pin bearing lid is sling and is installed to the crank-pin of the crankshaft；
3) the left limit block and right limit block are fixedly installed on the positioning plate, at this time the crank pin bearing lid
State vertically downward has been fixed on the crankshaft and has been in completely, and come loose lifting appliance；
4) the supreme stop of crank-pin jiggering that crank pin bearing lid will have been installed, since the limit of the setting tool is made
With relative displacement will not occur between the crank pin bearing lid and the crankshaft during jiggering；
5) connecting rod is hung in into machine frame inside, the connecting rod and the crank pin bearing lid pairing is made to splice and pass through bolt
It is fixedly connected, removes the setting tool of crank pin bearing lid two sides later；
6) it according to the firing order of each cylinder of the diesel engine, repeats step 1)~step (7), it is successively that each cylinder is corresponding
Crank pin bearing lid is respectively installed to position；
The method that the crank pin bearing lid is dismantled with connecting rod includes the following steps:
When a) removing the crank pin bearing lid, first when the crank-pin of crankshaft is located at top dead centre, the fixation is installed
Then tool removes the connecting rod；
B) by the crank-pin jiggering to bottom dead center position, then the crank pin bearing lid is connected with lifting appliance, removed
Left limit block, right limit block and the positioning plate of the setting tool；
C) the crank pin bearing lid is hung out outside machine using lifting appliance.
Compared with the mode of operation that traditional crank pin bearing lid is installed, the present invention is mainly had the advantage that
1, crank pin bearing lid is positioned using the setting tool, eliminates connecting rod and crank pin bearing lid splices process
In artificial centering process, improve craft precision；
