Description
Technical field
The present invention relates to engine component mounting technique field, and in particular to a kind of cylinder head guide pipe press-loading apparatus.
Background technology
The cylinder head guide pipe that engine cylinder is covered is one of extremely important part on cylinder cap, and general cylinder head guide pipe uses powder
Metallurgy is made, the cylinder head guide pipe exceptionally face of cylinder and interior cylindrical hole two parts composition, the conduit that external cylindrical surface is pre-machined with cylinder cap
Bottom outlet is interference fit；Interior cylindrical hole is by casting out diameter D bottom outlet, final finishing air outlet valve push rod mounting hole.Valve
Require there is a good stationarity in high engine speeds running, thus cylinder head guide pipe to press-fit quality extremely important.Here carry
To the quality that press-fits press-fit depth, the axiality of conduit bottom outlet assembling, cylinder cap on cylinder head guide pipe and cylinder cap including cylinder head guide pipe
Conduit flawless during press-fiting is produced.
As shown in figure 1, cylinder head guide pipe press-loading apparatus of the prior art generally includes to press-fit sleeve 11 and press-fits mandrel 12,
When press-fiting, the required cylinder head guide pipe 13 press-fited is correctly put into and press-fited in sleeve 11, now cylinder head guide pipe 13 should be vertical
In the orifice position of conduit bottom outlet 14；The insertion of mandrel 12 will be press-fited to press-fit in sleeve 11, the bottom for press-fiting mandrel 12 props up cylinder cap
The upper surface of conduit 13, the upper end for press-fiting mandrel 12 is tapped using hammer manually, and cylinder head guide pipe 13 is interference fitted into press-in conduit
In bottom outlet 14.Because during the press-fiting of cylinder head guide pipe 13,45 degree of chamferings only by the end of cylinder head guide pipe 13 enter at it
Guide effect is played when in conduit bottom outlet 14, because the power that hammering press-fits mandrel 12 manually is not that ensure that always along cylinder
What the axis direction of lid conduit 13 and conduit bottom outlet 14 applied, so that cylinder head guide pipe 13 relatively holds with conduit bottom outlet 14 when press-fiting
Easily there is bias, and operative employee can not check cylinder head guide pipe 13 and press-fit bias, when circular hole in later process finishing conduit,
Occur that aperture is singly inclined, the consequence caused is cylinder cap gas leakage, serious will cause cylinder cap to scrap.

The centre bore 42 of sleeve is engaged with cylinder head guide pipe 51, is provided with the inwall of installation sleeve 41 for the ring with cylinder head guide pipe 51
The position limiting structure that connected in star 52 is engaged.The positive and negative of cylinder head guide pipe 51 can preferably be recognized by the program, prevent cylinder cap from leading
Pipe 51 is wrongly installed, it is ensured that the correctness press-fited.It is understood that when press-fiting mandrel 31 and moving downward, being installed promoting
Sleeve 41 and cylinder head guide pipe 51 are moved downwardly together, until cylinder head guide pipe 51 is pressed onto position.
Specifically, it is provided with radially fixed hole on inwall, position limiting structure includes trip bolt 83, the first spring 82 and can
The locking ball 81 headed into annular groove 52, trip bolt 83 is arranged in radially fixed hole close to press-fiting the one of sleeve 21
End, one end of the first spring 82 is connected with trip bolt 83, and the other end of the first spring 82 is connected with locking ball 81.So in peace
During dress, locking ball 81 is headed into the annular groove 52 of cylinder head guide pipe 51 by the restoring force of the first spring 82, cylinder cap is realized
Fixation of the conduit 51 in installation sleeve 41；Meanwhile, adjustment trip bolt 83 being screwed into depth and can make in radially fixed hole
The connection obtained between cylinder head guide pipe 51 and installation sleeve 41 is more solid and reliable.
In order to provide connection reliability of the cylinder head guide pipe 51 in installation sleeve 41, the number in radially fixed hole can be with
For two, two radially fixed holes are oppositely arranged on the both sides of the centre bore 42 of installation sleeve；Set respectively in two radially fixed holes
Limited bit architecture.
As shown in Fig. 2 and Fig. 3 and Fig. 7 and Fig. 8, in the another embodiment that the present invention is provided, press-fit the outer of mandrel 31
Annular locking groove 74 in place can be provided with periphery, the first radially installed hole can be provided with by press-fiting on sleeve 21, the
Can be provided with one radially installed hole second spring 72 and for annular locking groove 74 is engaged in place the first steel ball
71, one end of second spring 72 on the first steel ball 71 away from the side for press-fiting mandrel 31 with being connected, the other end of second spring 72
It is connected with the first T-shaped latch 73 set on the outer wall at the first radially installed hole.So position is pressed onto in cylinder head guide pipe 51
When, under the restoring force effect of second spring 72, the first steel ball 71 by the cooperation of auto-extending and annular locking groove 74 in place,
It is preferably spacing so as to be carried out to the motion for press-fiting mandrel 31, limit and press-fit mandrel 31 and continue to move downward and cause
The press mounting dimension of cylinder head guide pipe 51 is overproof to be occurred, while locking groove 74 can undertake most of next in place for the first steel ball 71 and annular
From the applying power for press-fiting mandrel 31, the first steel ball 71 can pass through welding manner with second spring 72, the first T-shaped three of latch 73
Connection, belongs to consumable accessory in the present invention, by checking that the press mounting dimension precision of cylinder head guide pipe 51 judges after using certain frequency
Its degree of wear, integral replacing is needed when beyond error range, and improving assistant pressing tool includes press-fiting mandrel, press-fits sleeve etc.
The service life of other precise parts.Entirely press-fit operating process simple and reliable, cylinder head guide pipe can be avoided because excessively bearing pressure
Underbead crack occurs caused by filling power, improves the reliability requirement of engine.It is understood that when being press-fit into place,
First steel ball 71 enters in the presence of the elastic force of second spring 72 in annular locking groove 74 in place, annular locking groove in place
74 be that can wrap the spheroid area that the first steel ball 71 is more than 1/2nd by the hemispherical dome structure being machined into so that
The area of endurance is big as far as possible；Press-fit after end, manually the T-shaped latch 73 of outside drawing first so that the first steel ball 71 times
Position, then carry out cylinder head guide pipe 51 below and press-fit work.
Further, press-fit and second radially installed corresponding with the first radially installed hole is also provided with sleeve 21
Can be provided with hole, the second radially installed hole the 3rd spring 75 and for annular in place locking groove 74 be engaged second
Steel ball, one end of the 3rd spring 75 on the second steel ball away from the side for press-fiting mandrel 31 with being connected, the other end of the 3rd spring 75
It is connected with the second T-shaped latch 76 set on the outer wall at the second radially installed hole, so as to pass through the first steel ball 71 and
The cooperation of two steel balls respectively with annular locking groove 74 in place, is realized to press-fiting the more preferable spacing of mandrel 31, and then preferably protect
That has demonstrate,proved cylinder head guide pipe 51 press-fits quality.
It the above is only the preferred embodiment of the present invention, it should be pointed out that these embodiments are merely to illustrate the present invention
Rather than limitation the scope of the present invention, moreover, after present disclosure has been read, relevant technical staff in the field can be with
Various changes or modification are made to the present invention, these equivalent form of values equally fall into the model that the application appended claims are limited
Enclose.
