Description

A kind of vehicle engine exhaust divided manifold device for detecting sealability
Technical field
The invention belongs to leak-testing apparatus technical field, particularly relate to a kind of vehicle engine exhaust divided manifold sealing Detection device.
Background technology
Exhaust manifold is one of part that in electromotor, working condition is the most severe, subjects ambient temperature in work process To the variations in temperature of nearly thousand degrees Celsius, be also satisfied the requirement of air-tightness and durability simultaneously.Modern car engine is towards little Type, the direction of high effect are developed, and pressure at expulsion also increases, and this proposes higher wanting to the sealing property of exhaust manifold Ask.The sealing how improving exhaust manifold and the sealing how detecting exhaust manifold become requisite link.
The air inlet of exhaust manifold is provided with adpting flange, is connected by exhaust manifold by tighting a bolt on adpting flange On engine cylinder-body, in order to ensure sealing therebetween, need between adpting flange and engine cylinder-body, arrange one Layer pad.
The sealing of detection exhaust manifold has become as a requisite link, it is therefore desirable to design one can mould Intend enmgine exhaust and use process, and accurately detect the detection device of exhaust manifold sealing property.
Summary of the invention
The present invention solves technical problem present in known technology and provide a kind of simple in construction, simple operation, can be accurate Really detect the vehicle engine exhaust divided manifold device for detecting sealability of exhaust manifold sealing property.
The present invention solves that technical problem is adopted the technical scheme that present in known technology: a kind of automobile engine Exhaust manifold device for detecting sealability includes that casing, box house are provided with simulation of engine cylinder body, on simulation of engine cylinder body Being provided with engine cylinder-body sealing surface, engine cylinder-body sealing surface is positioned at the top of casing, and engine cylinder-body sealing surface is offered There is multiple connecting hole corresponding with exhaust manifold;The top of casing is additionally provided with multiple liftable compression pawl, compresses pawl and is positioned at The both sides of engine cylinder-body sealing surface;The inflation mechanism and sealing propertytest machine that can dock it is provided with exhaust manifold on casing Structure.
Advantages of the present invention and good effect be: puts engine cylinder-body and sealing surface thereof by proposing in casing upper mold, real Testing stand upper mold intends the connection of engine cylinder-body and exhaust flange now, and operating process is simple, and testing result is accurate.
Preferably: described compression pawl is driven by hydraulic jack, and hydraulic jack is arranged at box house.
Preferably: the both sides of described engine cylinder-body sealing surface are respectively symmetrically and are provided with 2 compression pawls.
Accompanying drawing explanation
Fig. 1 is the structural representation of the present invention.
In figure: 1, engine cylinder-body sealing surface;2, pawl is compressed;3, adpting flange;4, casing;5, exhaust manifold;6, inflation Mechanism;7, sealing propertytest mechanism.
Detailed description of the invention
For the summary of the invention of the present invention, feature and effect can be further appreciated that, hereby enumerate following example and describe in detail such as Under:
Referring to Fig. 1, the present invention includes that casing 4, casing 4 are internally provided with simulation of engine cylinder body, simulation of engine cylinder Being provided with engine cylinder-body sealing surface 1 on body, engine cylinder-body sealing surface 1 is positioned at the top of casing 4, engine cylinder-body sealing surface Multiple connecting hole corresponding with exhaust manifold is offered on 1;The top of casing 4 is additionally provided with multiple liftable compression pawl 2, pressure Tight pawl 2 is positioned at the both sides of engine cylinder-body sealing surface 1;The inflation mechanism 6 that can dock and close it is provided with exhaust manifold on casing 4 Feng Xing testing agency 7.
In the present embodiment, described compression pawl 2 is driven by hydraulic jack, and it is internal that hydraulic jack is arranged at casing 4.
In the present embodiment, the both sides of described engine cylinder-body sealing surface 1 are respectively symmetrically and are provided with 2 compression pawls 2.
The work process of the present invention is: place pad on engine cylinder-body sealing surface 1, then by the company of exhaust manifold 5 Acting flange 3 is pressed on pad, adjusts the position between three and makes the connecting hole on engine cylinder-body sealing surface 1 and exhaust manifold 5 Upper corresponding air inlet alignment;Now hydraulic jack action drives compression pawl is pressed for 2 times, by adpting flange 3, pad, engine cylinder Body sealing surface 1 is pressed together;Then the air vent of the appendix of inflation mechanism 6 with exhaust manifold 5 it is tightly connected and carries out Inflation;When air pressure reaches designated value, observe quantity of gas leakage by sealing propertytest mechanism 7, thus analyze the close of exhaust manifold Sealing property.
