Description
Technical field
The present invention relates to a kind of cylinder of diesel engine, the specifically bolt device of cylinder block.
Background technique
Internal combustion engine is a kind of very important dynamic power machine, is had extensively in many fields of industrial production and social life
Using.Wherein, diesel engine is an important branch of internal combustion engine, in the dynamic of transport facility, agricultural machinery and engineering machinery
There is irreplaceable status in terms of power.
Cylinder block is development of the important component in diesel engine with internal-combustion engine technology, and the power per liter of engine constantly mentions
It rises, the requirement to the reliability of internal combustion engine is higher and higher, wants accordingly to the intensity and rigidity of cylinder of diesel engine part
Ask also higher and higher.
Under normal conditions, cylinder block is connected through bolt-through cylinder block with body by one very long.But
It is the convenience in order to be linked and packed, through there are gaps between the diameter of bolt and bolt hole.These gaps make diesel engine work
Vibration is generated between body and cylinder block in the process, the safety for influencing diesel engine work through bolt fracture can be made when serious.
Summary of the invention
The purpose of the present invention is to provide the vibrations that can be effectively reduced in working process of diesel engine to cylinder of diesel engine
Influence, improve working process of diesel engine in safety and economy a kind of cylinder block swelling damping bolt device.
The object of the present invention is achieved like this:
A kind of bolt device of cylinder block swelling damping of the present invention, it is characterized in that: including the body of bolt, bolt shell, pressure oil
Piston, bolt shell are mounted on the outside of the body of bolt, form annular groove between the both ends and the body of bolt of bolt shell, the body of bolt
Both ends are thread segment, and a pressure oil piston is respectively provided on the thread segment at both ends, and a part of pressure oil piston is located at its corresponding spiral shell
The outside of line section, the rest part of pressure oil piston are located between its corresponding bolt shell and the body of bolt, and the pressure oil of the part is living
Reservoir is formed between plug and bolt shell and the body of bolt, reservoir is communicated with annular groove.
The present invention may also include:
1, the middle part of bolt shell is mutually fixed with the body of bolt.
2, the pressure oil piston portion between bolt shell and the body of bolt is arranged on the inner wall being in contact with the body of bolt
Seal oil ring.
3, when thread segment installation nut, corresponding pressure oil piston is moved under the extruding of nut to body of bolt middle part direction
Dynamic, thus by the liquid compressed in reservoir to squeezing in annular groove, the bolt shell for being is to external expansion.
Present invention has an advantage that
1, oil groove and pressure oil piston are set on bolt in cylinder block, so that cylinder block is not increasing complicated setting, only
The swelling of bolt is only just realized by the expansion of oil.Principle is simple and convenient to operate, and can effectively reduce the vibration of bolt, guarantees gas
The safety of cylinder body in operation.
2, it is also provided with two layers of annular oil sealing slot on pressure oil piston, prevents a large amount of leakages of the oil in reservoir from influencing swelling
Effect.Even if having minimal amount of oil leakage, can also it prevent screw bolt and nut from getting rusty.
Detailed description of the invention
Fig. 1 is end view of the invention；
Fig. 2 is the coupling part schematic diagram that cylinder block swelling runs through bolt；
Fig. 3 is overall schematic of the invention；
Fig. 4 is the schematic diagram of pressure oil piston.
Specific embodiment
It illustrates with reference to the accompanying drawing and the present invention is described in more detail:
In conjunction with Fig. 1-4, cylinder block swelling Shock-proof bolt of the present invention specifically includes that screw thread 1, pressure oil piston 2, bolt shell
3, the body of bolt 4, reservoir 5, seal oil ring (bolt upper and lower ends structure is identical) 6.
There are annular groove between bolt body case 3 and the body of bolt 4, the oil stored in reservoir 5 is flowed into.Bolt
On the position of pressure oil piston 2 be overlapped with screw thread, when toward nutting on bolt, nut can push down on pressure oil piston.
Two seal oil rings 5 are set on pressure oil piston 2, prevent the oil in bolt from overflowing outward.For the convenience of body of bolt processing, bolt
It is closely connected between shell 3 and the body of bolt 4 at middle part.
The present invention pushes pressure oil piston using the screwing force of nut when tightening end nut and lower end nut axially, will
Liquid in fluid reservoir is pressed against expanding trough；Bolt shell 3 is arranged very thin, when the liquid in upper and lower fluid reservoir is squeezed into, spiral shell
Bolt shell expands outward, fills up fit-up gap.Two oil seal rings 5 being in contact in pressure oil groove with oil, prevent oil spill from going out.
Specific swelling mechanism of the invention is as shown in fig. 1.It is provided with fluid reservoir 5 in the body of bolt 4 and threaded connection section, and
Annular expanding trough is left, bolt shell 3 is formd, pressure oil piston 2 is provided between fluid reservoir 5 and screw thread 1, on pressure oil piston
Provided with seal oil ring 6.
The installation embodiment of cinch bolt is in the present invention, which is inserted into cylinder block bolt hole, under cylinder block
Portion is in contact with rack, first assembles pressure oil piston 2 in the junction of bolt lower thread and screw rod shaft, before this, must be really
Seal oil ring 6 it has been mounted in pressure maintaining oil piston 2, then toward nut is added on bolt, while tightening nut upwards, nut is pushed away
Dynamic pressure oil piston 2 pushes the oil of the inner pre-position of reservoir 5, makes the swelling of bolt lower part elder generation；Same mode is on cylinder block top
Bolt upper end implement, in the top pressure oil piston of cylinder block, then screw on end nut, upper end nut is during tightening
Pressure oil piston is pushed to make the top swelling of screw rod shaft.To realize swelling and the damping effect of bolt entirety.
