Abstract
An engine exhaust manifold assembly comprises an air inlet flange and an exhaust manifold connected with the air inlet flange in a welded mode. An air inlet hole and multiple bolt installation holes are formed in the air inlet flange, the air inlet hole is connected with the exhaust manifold in a welded mode, and the bolt installation holes are connected with engine bolts. A circle of isolation groove is formed in the part, around the air inlet hole, of the air inlet flange. Because the circle of isolation groove is formed in the part, around the air inlet hole, of the air inlet flange, when the exhaust manifold is connected with the air inlet flange in the welded mode, residual welding fluid will flow into the isolation groove without extending along the face of the flange, so that the nut installation region of the flange is kept clean, in the actual production process, polishing and other reworking conditions are not needed, the cost is lowered, and production efficiency is improved.
Description
Technical field
The present invention relates to enmgine exhaust, particularly a kind of engine exhaust manifold assembly.
Background technique
Need the waste gas of discharge to be collected by gas exhaust manifold during engine operation, by the purification of ternary catalyzing unit, and be discharged in air after reducing exhaust sound by silencing apparatus.
Along with the lightweight of motor and the layout of engine compartment more and more compacter, the design space of gas exhaust manifold is more and more less, and the distance that simultaneously result also between motor air outlet and manifold construction bolt is more and more nearer.
One of main technique of manifold assembly is welding, after manifold and flange welding, the weld seam of one fixed width can be produced at the root of manifold, because bolt mounting holes and inlet flange hole are leaned on very near, if therefore control deviation appears in technique, produce wide weld seam, weld seam will extend to the flange attachment face of nut, cause nut flange face fully can not contact with flange, cause mounting torque inadequate, flange attachment face produces the unfavorable condition of gas leakage.As there is this kind of situation, need the later stage to polish, ensure nut mounting zone have no effect assembling foreign material.This, by reducing the efficiency of work, improves beat and the cost of production simultaneously.
Summary of the invention
Object of the present invention, exactly in order to overcome above-mentioned the deficiencies in the prior art, provides a kind of engine exhaust manifold assembly, fully can ensure that the space of nut flange attachment face is not interfered by weld seam, ensures that nut is installed smoothly.
The object of the present invention is achieved like this: a kind of engine exhaust manifold assembly, comprises inlet flange and gas exhaust manifold, and gas exhaust manifold and inlet flange are welded to connect; Described inlet flange is provided with an inlet hole for being welded to connect with gas exhaust manifold, and multiple bolt mounting holes for being connected with engine bolt, the inlet flange around inlet hole is provided with a circle isolation channel.
Described gas exhaust manifold is connected and composed by stamping forming upper shell and lower shell body.
After described bolt mounting holes construction bolt, the distance on bolt border and inlet hole border is less than 5mm, and described isolation channel is arranged between bolt mounting holes and inlet hole.
Described isolation channel is arranged on the reverse side of inlet flange attachment face.
The thickness of described inlet flange is 8-10mm, and the section of described isolation channel is semi-circular, and diameter is 3mm.
Engine exhaust manifold assembly of the present invention is owing to the inlet flange around inlet hole being provided with a circle isolation channel.When gas exhaust manifold and inlet flange being welded to connect, unnecessary welding fluid can flow in isolation channel, and is unlikely to extend along flanged surface, the mounting zone of flange upper cap nut can be made to keep clean, do not affect installation.
Compared with the flange of not slotting, the isolation channel in the present invention can serve as the effect of moat, and the mounting zone of protection nut is not affected, and does not need to carry out the situation of doing over again such as polish again, reduce cost, improve manufacturing efficiency in the production process of reality.
Accompanying drawing explanation
Fig. 1 is the structural representation of engine exhaust manifold assembly of the present invention;
Fig. 2 is that the A-A of Fig. 1 is to sectional structure schematic diagram.
Embodiment
See Fig. 1, Fig. 2, engine exhaust manifold assembly of the present invention, comprise inlet flange 1 and gas exhaust manifold 2, gas exhaust manifold and inlet flange are welded to connect.Inlet flange is provided with an inlet hole 11 for being welded to connect with gas exhaust manifold, and multiple bolt mounting holes 12 for being connected with engine bolt, inlet flange around inlet hole is provided with a circle isolation channel 13, this isolation channel is arranged on the reverse side of inlet flange attachment face.After bolt mounting holes 12 construction bolt, the distance on bolt border and inlet hole border is less than 5mm, and isolation channel is arranged between bolt mounting holes and inlet hole.
Gas exhaust manifold 2 in the present invention is connected and composed by stamping forming upper shell 21 and lower shell body 22.
The thickness of the inlet flange 1 in the present invention is 8-10mm, and the section of isolation channel 13 is semi-circular, and diameter is 3mm.
The present invention is mainly used in vehicle engine exhaust divided manifold assembly.According to the cylinder number of motor, manifold has the flange suction port of respective numbers to assemble with it, and each suction port is welded with it by the frame set of manifold or pipeline assembly, and the pipeline of final each suction port is all pooled to an air outlet and discharges.
