Dress seat 4, existing oxygen sensor mounting seat is all to use solid bar to carry out machine add-on type, and surface roughness is poor, seals difficulty,
Also there is working (machining) efficiency low, the shortcomings such as waste of material rate is high.CN 204646377U disclosed " a kind of oxygen sensor base with urge
Change the mounting structure of device ", including oxygen sensor base and catalyst converter, catalyst converter includes that inside is filled with outside the metal of catalyst
Shell, it is characterised in that the base of described oxygen sensor is located on catalyst converter shell, oxygen sensor is located on oxygen sensor base,
Metal shell is provided with hole, and this hole makes the catalyst in catalyst converter shell connect with oxygen sensor base.Its advantage is: improve
Service behaviour, reduces the design difficulty of catalyst converter correlated parts, being designed and manufactured as originally of the catalyst converter of reduction.But oxygen senses
Device base yet suffers from above-mentioned deficiency, accordingly, it would be desirable to the oxygen sensor mounting seat of exploitation brand new.
Summary of the invention
It is an object of the invention to provide the mounting seat of a kind of oxygen sensor, it can be applicable to all ternary catalyzing units even
Adapter road is fixing to be connected, and not only seals reliable, and generalization degree is high, and can save material, alleviate weight, reduce and manufacture
Cost, improves production efficiency.
The mounting seat of a kind of oxygen sensor of the present invention, including oxygen sensor seat body, is characterized in that: described oxygen passes
Sensor seat body is stamping forming sheet metal component, and the center portion thereof position is adapter sleeve, is provided with on the inner peripheral surface H of described adapter sleeve
Screw thread, the upper end of described adapter sleeve is connected with an annular end face E, the shirt rim F of the excircle of this annular end face E and bending downwards
Being connected, the length of the more described adapter sleeve of length of this shirt rim F is short.
Further, described oxygen sensor seat body is arranged on the pipe of one stage catalyzing device one end, described oxygen sensor seat
The outer circumference surface G of the adapter sleeve at body central position passes through the via K location on described pipe, and described oxygen sensor seat is originally
Plane L around shirt rim F on body and via K is welded and fixed；The bottom of oxygen sensor and described oxygen sensor seat body
The inner peripheral surface H of adapter sleeve is threaded；It is provided with sealing gasket P between described oxygen sensor seat body and described oxygen sensor.
Further, the corrosion resistant plate stretching and punching that described oxygen sensor seat body uses thickness to be 1.5mm-2.5mm becomes
Type.
Preferably scheme is, described oxygen sensor seat body uses the trade mark of corrosion resistant plate to be SUS304 rustless steel, thickness
For 2mm.
Beneficial effects of the present invention: owing to using the oxygen sensor mounting seat of corrosion resistant plate Sheet Metal Forming Technology molding, raw material
Changed into sheet material by bar, can effectively save raw material, raw-material weight can reduce about 65%, and finished weight can reduce about 30%, with
Time also improve working (machining) efficiency, reduce production cost.Due to stamping forming oxygen sensor mounting seat itself roughness relatively
Good, the annular end face E of its upper end only need to i.e. can reach roughness and the planarity requirements of design by die reshaping, it is possible to ensures
Seal reliable.Can be applicable to be connected fixing with all ternary catalyzing unit connecting lines, generalization degree is high.

Detailed description of the invention
Below in conjunction with the accompanying drawings existing oxygen sensor seat and the present invention are further described.
Seeing Fig. 1, Fig. 2 and Fig. 3, the big up and small down round platform of existing oxygen sensor mounting seat 4 is stepped, have upper surface A,
Great circle side face B, roundlet side face C and centre bore periphery D.Existing oxygen sensor mounting seat is to use solid bar to carry out machine addition
Type, waste of material is big, needs to process great circle side face B, roundlet side face C and centre bore periphery D, expends man-hour long, produces effect
Rate is low；It addition, after bar blanking, the upper surface A roughness of existing oxygen sensor mounting seat is poor, it is necessary to by machining
Roughness and planarity requirements can be reached, otherwise seal difficulty.Existing oxygen sensor mounting seat 4 is arranged on one stage catalyzing device 5 one
On the pipe 3 of end, oxygen sensor 1 is connected with existing oxygen sensor mounting seat 4.
Seeing Fig. 4, Fig. 5 and Fig. 6, the mounting seat of a kind of oxygen sensor of the present invention, including oxygen sensor seat body
1, its prominent substantive distinguishing features is: described oxygen sensor seat body 2 is stamping forming sheet metal component, and the center portion thereof position is for connecting
Set, is provided with screw thread on the inner peripheral surface H of described adapter sleeve, and the upper end of described adapter sleeve is connected with an annular end face E, this annular
The shirt rim F of the excircle of an end face E and bending downwards is connected, and the length of the more described adapter sleeve of length of this shirt rim F is short.
Described oxygen sensor seat body 2 is arranged on the pipe 3 of one stage catalyzing device 5 one end, described oxygen sensor seat body
The outer circumference surface G of the adapter sleeve in centre passes through the via K location on described pipe 3, described oxygen sensor seat body
On shirt rim F and via K around plane L be welded and fixed；The bottom of oxygen sensor 1 and the company of described oxygen sensor seat body
The inner peripheral surface H of female connector is threaded；It is provided with sealing gasket P between described oxygen sensor seat body 2 and described oxygen sensor 1.
Sealing gasket P forms sealing with the annular end face E of described oxygen sensor seat body, it is ensured that gas does not leaks.
Described oxygen sensor seat body 2 uses thickness to be 1.5mm-2.5mm(millimeter) corrosion resistant plate stretching and punching become
Type.Because the inner peripheral surface H of adapter sleeve needs to arrange female thread and the degree of depth is relatively big, so needing repeatedly drawing in the fabrication process
Punch forming.
Oxygen sensor seat body 2 described in this example uses the trade mark of corrosion resistant plate to be SUS304 rustless steel, and thickness is 2mm(milli
Rice).
For guaranteeing that oxygen sensor reaches to design requirement with the sealing of oxygen sensor seat body connecting portion, annular need to be improved
The flatness of end face E, i.e. needs annular end face E is carried out die reshaping；Also need to inner peripheral surface H is carried out tapping, in being formed
Screw thread, for carrying out threaded with oxygen sensor.
