Abstract
The utility model discloses a kind of valve oil seal auxiliary installation tools, including frock entity, described frock entity one end is impact end surface, and the other end is valve oil seal entrance hole, and the valve oil seal entrance hole is made of bellmouth, the stepped hole of different-diameter and air cushion hole；Entrance hole extends inwards from end face, puts in order as bellmouth, stepped hole and air cushion hole from end face inwards by big and small.This valve oil seal auxiliary installation tool carries out not only having can guarantee that external force was uniformly transferred to valve oil seal during valve oil seal press fitting, but also can knock in process damage from valve oil seal；Simultaneously valve oil seal is also avoided to re-replace and valve guide bushing outer circle matching surface is caused to be damaged.Can be effectively cost-effective, improve production efficiency.
Description
Technical field
The utility model is related to the auxiliary tool in the assembling process of engine cylinder cap more particularly to a kind of valve oils
Seal auxiliary installation tool.
Background technology
Engine valve oil seal is installed on the valve guide bushing of cylinder head using equipment automatic press mounting, but due to Equipment
And the characteristic of oil sealing in itself, occur valve oil seal rebound often after equipment press fitting, cause valve oil seal press fitting not in place, need to pull out
Again with new oil seal pressing, not only increase post staff labor intensity, also add production cost；If valve oil seal press-loading device
, it is necessary to which waiting facilities reparation could be produced normally after failure, so as to influence production efficiency.
The prior art (Patent No.：ZL201520354302.9) although valve oil seal can be corrected, its impact end surface is set
Globulate is counted, this affects the use direction of power in practical operation, it is possible to cause local pressure is uneven to cause press fitting not
In place；It followed by imports nose end and is designed as bellmouth, this to be difficult to be formed between the valve oil seal of stepped annular and bellmouth
Stable adhesive force, easily shake is dropped in correction course；Its bellmouth material therefor is plastics, is often exerted oneself with valve oil seal
Extruding is easily deformed damage.
Utility model content
To solve, problem above provides a kind of reduction labor intensity to the utility model and production cost, timing stress are equal
It is even so as to the valve oil seal auxiliary installation tool improved labor efficiency.The valve oil seal auxiliary installation tool, including frock
Entity, described frock entity one end be impact end surface, the other end be valve oil seal entrance hole, the valve oil seal entrance hole
It is made of bellmouth, stepped hole and air cushion hole, entrance hole extends inwards from end face, puts in order as bellmouth, stepped hole
With air cushion hole from end face inwards by big and small.
Further, stepped hole internal diameter matching valve oil seal outer diameter.
Further, the frock entity both ends end face is vertical with frock solid centre axis.
Further, the small end of the bellmouth connects with the macropore of stepped hole, and diameter is equal.
The advantageous effect of the utility model compared with prior art：In order to slow during the utility model progress valve oil seal press fitting
It rushes the air pressure of frock entrance hole air column formation and reversed resistance occurs and devises air cushion hole when frock being made to be struck under,
Not only it can guarantee that external force was uniformly transferred to valve oil seal, but also process damage can knocked in from valve oil seal；Also avoid gas simultaneously
Door oil sealing re-replaces and valve guide bushing outer circle matching surface is caused to be damaged.In equipment fault, first valve oil seal is inserted in
On valve guide bushing, then frock impact end surface is gently tapped with hammer, valve oil seal is made, which to be pressed onto on the qualified position line, can complete gas
The manual installation of door oil sealing, without waiting for press-loading device reparation, so as to improve production efficiency.
Description of the drawings
Fig. 1 is the utility model section view；
Fig. 2 is the utility model operation chart.
It is marked in figure：1- impact end surfaces, 2- bellmouths, 3- cascade rings, 4- air cushions hole, 5- frock entities, 6- valves
Oil sealing, 7- valve guide bushings, 8- engine cylinder covers.
Specific embodiment
The utility model is described in further detail below in conjunction with the accompanying drawings.
A kind of valve oil seal auxiliary installation tool as shown in Figure 1, including frock entity 5, described 5 one end of frock entity is
Impact end surface 1, the other end are valve oil seal entrance hole, and the valve oil seal entrance hole is by bellmouth 2, stepped hole 3 and sky
Gas cushion hole 4 is formed.The valve oil seal entrance hole extends inwards from end face, puts in order as bellmouth 2,3 and of stepped hole
Air cushion hole 4 is from end face inwards by big and small.3 internal diameter of stepped hole matching 6 outer diameter of valve oil seal.The frock
5 both ends of entity and 5 central axis of frock entity.The small end of the bellmouth 2 connects with the macropore of stepped hole 3, diameter phase
Deng.
The utility model use is described in further details with reference to Fig. 2：
When being pressed valve oil seal 6 not in place using the auxiliary mould calibration equipment, as long as the entrance hole of frock is inserted in
It needs on the valve oil seal done over again 6, frock impact end surface 1 is gently beaten with hammer, valve oil seal 6 is made to be pressed onto on the qualified position line
, so as to reduce labor intensity, save production cost.During equipment fault, first valve oil seal 6 is inserted on valve guide bushing 7, then
With above method can quick assembling valve oil seal 6, without waiting for equipment reparation, so as to improve production efficiency.
