Abstract
The utility model discloses a kind of diesel engine cylinder block bowl-type patch that can be achieved reliably to seal, including patch body（1）, it is characterised in that：In the patch body（1）Outer wall on offer annular groove（2）, and the annular groove（2）The plane at place and patch body（1）Plane where top end opening is mutually parallel, annular groove（2）Longitudinal section for semicircle shape, patch body（1）Wall thickness for a, then annular groove（2）Radius be 0.2 0.5a.This is a kind of simple in sturcture, ingenious in design, and easy to transform, of low cost, popularization can easily realize the diesel engine cylinder block bowl-type patch reliably sealed.
Description
Technical field
The utility model is related to matched with diesel engine parts technical field, particularly a kind of diesel oil that can be achieved reliably to seal
Machine cylinder body bowl-type patch.
Background technology
DEUTZ No.1 auto 498 and 4DD diesel engine cylinder block rear end faces have a fabrication hole of two oil duct Φ 18H8, and when assembling needs to use
Bowl-type patch is aided with 962T anaerobic adhesives, and hammering is packed into, and realizes the sealing of two oil duct fabrication holes.But traditional bowl-type patch
Sealing reliability is bad, and there are still the phenomenon that oil leak, it is often more important that, this oil leakage phenomenon is using airtight detection in assembling
Can not be detected, could only be found in diesel engine test run, there are it is more serious the problem of；Although plug screw can be utilized close
The mode of envelope is improved, but the processing of above-mentioned cylinder body needs to utilize building-block machine special plane production line, if desired for improvement, one
Aspect workload is larger, on the other hand needs larger investment, the cost is relatively high；And other traditional improvement modes are as improved
The processing circularity in hole, roughness, assembling work requirement etc., are proven, can not thoroughly realize the purpose reliably sealed.
Therefore need one kind being capable of solution to the problems described above or device now.
The content of the invention
The utility model is to solve the above-mentioned deficiency present in the prior art, proposes that one kind is simple in structure, design is skilful
It is wonderful, it is easy to transform, it is of low cost, promote the diesel engine cylinder block bowl-type patch that can easily realize and reliably seal.
The technical solution of the utility model is：A kind of diesel engine cylinder block bowl-type patch that can be achieved reliably to seal, bag
Include patch body 1, it is characterised in that：Annular groove 2, and 2 institute of the annular groove are offered on the outer wall of the patch body 1
Plane be mutually parallel with the plane where 1 top end opening of patch body, longitudinal section of annular groove 2 is semicircle shape, patch
The wall thickness of body 1 is a, then the radius of annular groove 2 is 0.2-0.5a.
The annular groove 2 is one, and annular groove 2 is in the longitudinal direction by two decile of outer wall of patch body 1.
The annular groove 2 is the 2-4 that is mutually parallel, and these annular grooves 2 are will be on the outer wall of patch body 1 uniformly
Distribution.
The utility model compared with the existing technology, has the following advantages that：
The achievable diesel engine cylinder block bowl-type patch reliably sealed of this kind of structure type, it is simple in sturcture, ingenious in design,
It is directed to traditional bowl-type patch the problems of in use, is made improvements on the basis of traditional bowl-type patch,
The annular groove of 962T anaerobic adhesives can be accommodated by being opened up on the side wall of patch body, and to the section configuration, size, quantity of the annular groove
Specific restriction is made that with the distribution relation on patch body, and this bowl-type patch can be in the interference fit process with cylinder body
In, retain a complete ring shaped anaerobic rubber ring, so as in the case where not losing traditional bowl-type patch function, significantly improve close
The reliability of envelope.And the manufacture craft of this bowl-type patch is simple, manufacture it is of low cost, it can be said that it possess it is a variety of
Advantage, particularly suitable for promoting and applying in the art.
Description of the drawings
Fig. 1 is the sectional view of the utility model embodiment.
Fig. 2 is the stereoscopic-state schematic diagram of the utility model embodiment.
Fig. 3 is the working state schematic representation of the utility model embodiment.
Specific embodiment
Below in conjunction with description of the drawings specific embodiment of the present utility model.As shown in Figure 1, Figure 2, Figure 3 shows：One kind can be real
The diesel engine cylinder block bowl-type patch now reliably sealed, including patch body 1, annular groove is offered on the outer wall of patch body 1
2, the plane where this annular groove 2 is mutually parallel with the plane where 1 top end opening of patch body, and the longitudinal direction of annular groove 2 is broken
Face is semicircle shape, and the wall thickness of the patch body 1 is a, then the radius of annular groove 2 is 0.2-0.5a.
When the quantity of annular groove 2 is one, this annular groove 2 is arranged on the middle part of patch body 1, i.e., in the longitudinal direction will
Two decile of outer wall of patch body 1.
When the quantity of annular groove 2 is 2-4, all annular grooves 2 are all mutually parallel, and these annular grooves 2 will be filled in
It is uniformly distributed on the outer wall of piece body 1.
When traditional bowl-type patch is assembled, by the way of interference fit, while 962T anaerobic adhesives are equipped with.Interference
Amount is in addition to being used to fix patch and cylinder body resistance oil pressure, it may have part sealing function；Anaerobic adhesive is present in patch outer wall
Between cylinder bore inner wall, it may have sealing function；But when traditional bowl-type patch is sealed, due to being that interference is matched somebody with somebody
It closes, therefore the anaerobic adhesive for some is extruded in assembling process, is caused its binding site of anaerobic adhesive underfill and is lost
Sealing function；
And when being assembled using the bowl-type patch of this kind of structure type, still by the way of interference fit, and fill in
962T anaerobic adhesives are filled between piece body 1 and the inner wall of cylinder bore, due to offering at least one on the outer wall of patch body 1
Annular groove 2 has enough 962T anaerobic adhesives in assembling process and enters in annular groove 2, forms anaerobism rubber ring, and in necessity
When, above-mentioned annular groove 2 may be arranged as being mutually parallel it is multiple, to ensure sealing effect.
