Description
Technical field
The utility model belongs to technical field of engines, and in particular to a kind of diesel engine cylinder cover valve valve seat dismantles work
Tool.
Background technology
Engine needs to carry out maintaining according to the time of regulation, be wherein frequently necessary to during the opening and inspecting of cylinder head by
Valve seat removes, and belongs to interference fit between valve seat and bore, and it is extremely difficult to disassemble process.In the prior art, it is common and can
Capable valve seat disassembling method is：Using a part for boring machine or milling machine processing removal valve seat, change the shape of valve seat and stress shape
Condition, so as to take out valve seat, such method longevity of service, efficiency is low, and danger is big and is easily damaged bore etc..Some other valves
Seat dismounting valve seat instrument is such as：1. self-made tool is welded on valve seat, valve seat is taken out of by opposition, such method needs
Special efficient staff, while cylinder cover valve seat bore is also easily damaged, the valve seat of dismounting can not reuse.2. lead to
Claw card throttle valve seat is crossed, crowbar is agitated and takes out valve seat insert, such methods and instruments are not easy fixed placement, and valve seat is pulling out
Shi Shouli is not vertically oriented, and is easily damaged cylinder head upper valve base bore.3. by traveling nut, screw rod by rotary motion and power
Square is converted into acting on the pulling force on valve seat, drives valve seat for linear motion by fixture block while screw rod is pulled outward and is allowed to
Departing from cylinder head, such method main problem is fixture block, and fixture block easily separates during moving upwards from valve seat orifice,
Fixture block cannot stuck valve seat, success rate is not high, and single set instrument is only applicable to the dismounting of single valve seat；All of above dismounting valve seat
Method causes maintenance service greatly to perplex.
Utility model content
In order to solve the above technical problems, the purpose of this utility model is to propose a kind of diesel engine cylinder cover valve valve seat dismounting
Instrument.
The utility model adopts the following technical scheme that complete above-mentioned purpose：
A kind of diesel engine cylinder cover valve valve seat extracting tool, the extracting tool have screw rod；Under the screw rod
End and sleeve connection；The sleeve is that simultaneously resilient sleeve of the tensioner in valve seat insert can be moved up and down in valve seat insert；
There are multiple flutings being uniformly distributed along the circumference on the middle and lower part periphery of the sleeve；It is provided in the sleeve and matches somebody with somebody with its interference
The tie rod of conjunction；The tie rod is the circular cone structure in flaring footpath from top to bottom；The top of the tie rod, which has, places
Nut II in sleeve；Having between the tie rod and nut II makes the gap that sleeve moves up and down；With sleeve connection
The screw rod pass through the upper surface that the nut II matched somebody with somebody is supported on tie rod kissed with it；It is additionally provided with above the sleeve and spiral shell
The nut III of bar thread fitting；Stent is also equipped on the screw rod；There is on the stent multiple be uniformly distributed along the circumference
Screw；The lower end of multiple screws is supported on through the stent on the mounting surface of required dismounting valve seat insert；The branch
The nut I with screw flight cooperation is provided with above frame.
The utility model proposes a kind of diesel engine cylinder cover valve valve seat extracting tool, using sleeve tensioner in air valve
In seat, the dismounting of valve seat insert is realized by the cooperation of screw rod and nut, the dismounting of single valve seat is not only applicable to, improves
The applicability of the extracting tool, while sleeve is evenly distributed on valve seat circumference after spreading, valve seat from cylinder head when stress it is equal
It is even, valve seat and bore will not be damaged in disassembly process substantially, improves the economy of the extracting tool；With it is economic and practical,
It is simple in structure, make be simple and convenient to operate, securely and reliably, the characteristics of use scope is wide.

Specific embodiment
The utility model is illustrated with reference to the drawings and specific embodiments：
As shown in Figure 1, a kind of diesel engine cylinder cover valve valve seat extracting tool, the extracting tool has screw rod 1；Institute
The lower end for stating screw rod 1 is connected with sleeve 7；The sleeve 7 for can be moved up and down in valve seat insert and tensioner in valve seat insert
Interior resilient sleeve；With reference to Fig. 2, Fig. 3, there are multiple flutings being uniformly distributed along the circumference on the middle and lower part periphery of the sleeve 7；Institute
The tie rod 8 being interference fitted with it is provided in the sleeve 7 stated；With reference to Fig. 5, Fig. 6, the tie rod 8 is from top to bottom gradually
Expanding circular cone structure；The top of the tie rod 8 has the nut II 3 being placed in sleeve；The tie rod 8 and spiral shell
Having between mother II 3 makes the gap that sleeve moves up and down；The screw rod 1 being connected with sleeve 7 passes through the nut II 3 kissed and matched somebody with somebody with it
It is supported on the upper surface of tie rod 8；The top of the sleeve 7 is additionally provided with the nut III 9 with screw flight cooperation；The spiral shell
Stent 6 is also equipped on bar；With reference to Fig. 2, there are multiple screws 5 being uniformly distributed along the circumference on the stent 6；Multiple screws
5 lower end is supported on through the stent 6 on the mounting surface of required dismounting valve seat insert；The top of the stent 6 is provided with
With the nut I 2 of screw flight cooperation.
In use, first removing stent 6 and screw 5 from screw rod 1, first tie rod 8 is positioned over inside valve seat and plays branch
Support acts on, and sleeve 7 is connected remaining parts and is placed in valve seat, with the nut I 2 above monkey wrench turnbarrel, due to drawing
Certain gap is equipped between mandrel and nut II 3, sleeve 7 and nut II 3 can move down therewith, and 8 position of tension axis is constant,
7 circumference of sleeve is equipped with fluting, and the spreading at fluting during moving down of sleeve 7 continues turnbarrel outer nut I 2, will
The clearing of the distance between axis 8 and sleeve internal standard nut 3 is tensed, the outer diameter of 7 spreading rear boss of sleeve has been much larger than valve seat at this time
Stent 6 and screw 5 are sleeved on screw rod 1 and are supported on cylinder cover valve seat mounting surface by internal diameter, with monkey wrench rotating nuts I
2, by the rotary motion of nut I 2, the power that will act on monkey wrench is converted into acting on the upward pulling force of valve seat circumference,
The upward linear motion of the rotational movement sleeve 7 and valve seat of specialized nut I 2, so that valve seat departs from from cylinder head.
