Abstract
A catalytic converter casing is cylindrical. A boss is arranged on the casing, and a through mounting hole for mounting a sensor nut seat is formed in the boss. The position of the boss corresponding to the mounting hole is a plane, the inner surface of the sensor nut seat is a plane, and the two planes are in contact when the sensor nut seat and the boss are assembled. By means of the casing, the assembly and welding effect between the casing and the sensor nut seat can be improved effectively.
Description
Technical field
The present invention relates to a kind of housing of catalytic converter, belong to the technical field of automobile catalytic device housing design.
Background technique
Housing is one of critical piece of vehicle catalytic converter, along with the Vehicle Emission Control regulation of China is more and more stricter, increasing catalytic converter needs sensor installation (such as lambda sensor) on housing, so that Real-Time Monitoring catalytic converter is to the actual catalyzed conversion effect of motor Tail Gas when driving.
Shown in please refer to the drawing 1, but thing followed problem is, the assembling between the housing 1 ' of catalytic converter and sensor nut seat 2 ' and Welding Problems.If the erection welding quality of housing 1 ' and sensor nut seat 2 ' can not ensure, just may occur the problem of harmful exhaust gas leak, and sensor nut seat 2 ' also has the risk come off.
Therefore, need to provide a kind of new technological scheme to solve the problems of the technologies described above.
Summary of the invention
The object of the present invention is to provide the housing of the catalytic converter that a kind of assembling difficulty is lower.
For achieving the above object, the present invention adopts following technological scheme: a kind of housing of catalytic converter, described housing cylindrically, be provided with a boss on the housing, described boss be provided with run through and in order to the mounting hole of sensor installation nut seat, the position of the corresponding described mounting hole of described boss is plane, and the internal surface of described sensor nut seat is also plane, and described sensor nut seat and described boss are the contact of two planes when assembling.
As further improved technical scheme of the present invention, described boss is positioned at the middle part of the length direction of described housing.
As further improved technical scheme of the present invention, described boss is in a circumferential direction around described housing.
As further improved technical scheme of the present invention, described mounting hole is circular hole, and described sensor nut seat is circular and is contained in described mounting hole.
As further improved technical scheme of the present invention, described sensor nut seat is welded in described mounting hole.
As further improved technical scheme of the present invention, described sensor nut seat is lambda sensor nut seat.
As further improved technical scheme of the present invention, the surrounding of the corresponding described mounting hole of described boss is provided with an expansion section, and the width of described expansion section is greater than the width of described other parts of boss.
Compared to prior art, the present invention, by arranging boss, provides a flat contact surface to sensor nut seat, avoids the assembling of plane and cambered surface, reduce assembling difficulty; In addition, the contact of plane and plane efficiently reduces the matching gap between housing and sensor nut seat, improves the situation that gap is uneven, can help welding quality when improving follow-up welding process.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of prior art.
Fig. 2 is the schematic diagram of the housing of catalytic converter of the present invention when being separated with sensor nut seat.
Embodiment
Shown in please refer to the drawing 2, present invention is disclosed a kind of housing 100 of catalytic converter, described housing 100 cylindrically.Described housing 100 is provided with a boss 1, described boss 1 be provided with run through and in order to the mounting hole 11 of sensor installation nut seat 2.The position of the corresponding described mounting hole 11 of described boss 1 is plane 12, the internal surface 21(of described sensor nut seat 2 and bottom surface, shown in dotted line in ginseng Fig. 2) be also plane, described sensor nut seat 2 and described boss 1 are the contact of two planes when assembling.
Shown in please refer to the drawing 2, in illustrative embodiments of the present invention, described boss 1 is positioned at the middle part of the length direction of described housing 100.Described boss 1 is in a circumferential direction around described housing 100.Described mounting hole 11 is circular hole, and described sensor nut seat 2 is circular and is contained in described mounting hole 11.Preferably, described sensor nut seat 2 is welded in described mounting hole 11.Described sensor nut seat 2 is the lambda sensor nut seat in order to install lambda sensor.The surrounding of the corresponding described mounting hole 11 of described boss 1 is provided with an expansion section 13, and the width of described expansion section 13 is greater than the width of described other parts of boss 1.Setting like this, is convenient to be formed the plane 12 with larger area.
Compared to prior art, the present invention forms a boss 1 by processing technology on described housing 100.When sensor nut seat 2 and housing 100 assemble, surface of contact is by the contact that contact two planes becoming present of original plane with cambered surface, effectively reduce the matching gap between housing 100 and sensor nut seat 2, also improve the situation that between housing 100 and sensor nut seat 2, gap is uneven, thus help welding quality when improving follow-up welding process.
The housing 100 of catalytic converter of the present invention can be used for the housing design of various vehicle catalytic converter, effectively can improve the assembling between the housing 100 of catalytic converter and sensor nut seat 2 and welding effect.
In addition, above embodiment is only for illustration of the present invention and unrestricted technological scheme described in the invention, understanding of this description should based on person of ordinary skill in the field, although this specification reference the above embodiments are to present invention has been detailed description, but, those of ordinary skill in the art is to be understood that, person of ordinary skill in the field still can modify to the present invention or equivalent replacement, and all do not depart from technological scheme and the improvement thereof of the spirit and scope of the present invention, all should be encompassed in right of the present invention.
