Abstract
This patent is related to a kind of diesel engine exhaust manifold fixing device, including exhaust manifold, it is characterised in that：The root of exhaust manifold is respectively provided on two sides with mounting flange exhaust manifold, fixed counterbore is respectively arranged at two ends with mounting flange, fixed counterbore is abutted with fixed block, fixed block is installed with fixing bolt by unthreaded hole thereon, unthreaded hole is located at the middle part of fixed block, fixed block is stretched out in the threaded portion of fixing bolt, and the fixed counterbore of two on adjacent mounting flange is compressed by same fixed block.Advantage is：This patent can reduce influence of the thermic load for bolt, and then improve fixed reliability.
Description
Technical field
The invention belongs to diesel engine technologies field, and more particularly to a kind of diesel engine exhaust manifold is fixed
Device.
Background technology
At present, the development with diesel engine technologies and maturation, engine performance are improved therewith, what exhaust manifold bore
Thermal force also constantly increases.And exhaust manifold is the part that engine high-temperature waste gas passes through at first, it is chronically at and swashs heat, Quench
Worked under alternating capacity, if it can influence the reliability that engine works the problems such as causing gas leakage by thermal force in the course of the work
And the discharge performance of engine.As shown in figure 1, in the prior art, the mounting flange 2 of exhaust manifold both sides is directly by the He of spacer ring 6
Fixing bolt is fixed on body, and now fixing bolt is nearer apart from the heat transfer distances of exhaust manifold, by exhaust manifold thermal force
The influence of change is larger.
The content of the invention
The invention provides a kind of diesel engine exhaust manifold to solve technical problem present in known technology
Fixing device, the device can reduce influence of the thermic load for bolt, and then improve fixed reliability.
A kind of diesel engine exhaust manifold fixing device, including exhaust manifold, it is characterised in that：The root of exhaust manifold
Be respectively provided on two sides with mounting flange in exhaust manifold, in the fixed counterbore that is respectively arranged at two ends with of mounting flange, fixed counterbore with
Fixed block is abutted, and fixed block is installed with fixing bolt by unthreaded hole thereon, and unthreaded hole is located at the middle part of fixed block, the spiral shell of fixing bolt
Fixed block is stretched out in line portion, and the fixed counterbore of two on adjacent mounting flange is compressed by same fixed block.
The invention has the advantages and positive effects that：
Because the invention uses above-mentioned technical proposal, mounting flange is pressed on by fixed block, fixing bolt
On body, to replace directly mounting flange is pressed on body by fixing bolt and spacer ring in the prior art, significantly increase
The heat transfer distances between fixing bolt and exhaust manifold are added, and then have reduced the temperature of exhaust manifold, also reduced sharp hot, sharp
The change intensity of cold alternating capacity.Influence of the exhaust manifold thermic load for bolt is reduced, and then improves exhaust manifold and consolidated
Fixed reliability.
Brief description of the drawings
Fig. 1 is the structural representation of prior art；
Fig. 2 is the structural representation of the invention.
In figure：1st, exhaust manifold；2nd, mounting flange；3rd, there is fixed counterbore；4th, fixed block；5th, fixing bolt；6th, spacer ring.
Specific embodiment
For innovation and creation content, feature and effect of the invention can be further appreciated that, following examples are hereby enumerated, and
Accompanying drawing is coordinated to describe in detail as follows：
As shown in Fig. 2
A kind of diesel engine exhaust manifold fixing device, including exhaust manifold 1, the root of exhaust manifold is in exhaust manifold
Be respectively provided on two sides with mounting flange 2, be respectively arranged at two ends with fixed counterbore 3 in mounting flange, fixed counterbore is adjacent with fixed block 4
Connect, fixed block is installed with fixing bolt 5 by unthreaded hole thereon, fixed block is stretched out in the threaded portion of fixing bolt, positioned at adjacent fixation
Two fixed counterbores on flange are compressed by same fixed block.Each exhaust manifold is fixed by four pieces of fixed blocks, in order to embody
Go out fixed counterbore, so four pieces of fixed blocks do not have all showing.
The operating principle of the invention is：
Mounting flange is pressed on body by fixed block, fixing bolt, to replace in the prior art by fixing
Directly be pressed on mounting flange on body by bolt and spacer ring, has increased considerably the heat transfer between fixing bolt and exhaust manifold
Distance, and then the temperature of exhaust manifold is reduced, also reduce and swash heat, the change intensity of Quench alternating capacity.Reduce exhaust
Manifold thermic load and then improves the reliability fixed of exhaust manifold for the influence of bolt.
Although being described to the preferred embodiment of the invention above in conjunction with accompanying drawing, the invention is not
Above-mentioned specific embodiment is confined to, above-mentioned specific embodiment is only schematical, is not restricted, ability
The those of ordinary skill in domain is not departing from the invention objective and claimed under the enlightenment of the invention
Under ambit, many forms can also be made, these are belonged within the protection domain of the invention.
