Abstract
An automobile exhaust pipe where a sensor seat can be conveniently installed comprises a connection flange, a left descending pipe, a right descending pipe, a gathering pipe, a catalyst and the exhaust pipe. Two holes of the connection flange are respectively welded with one end of the left descending pipe and one end of the right descending pipe. The other end of the left descending pipe and the other end of the right descending pipe are simultaneously welded with one end of the gathering pipe; and the other end of the left descending pipe, the other end of the right descending pipe and the end of the gathering pipe are communicated. Two ends of the catalyst are respectively welded with the other end of the gathering pipe and one end of the exhaust pipe. A connection plane is arranged on the circumference of the exhaust pipe. The sensor seat with the plane bottom is welded to the connection plane. Due to the fact that planes are closely fit and have no gap, the automobile exhaust pipe solves the problem of a big fit clearance between two original irregular faces, and accordingly two parts are convenient to assemble and easy to weld, welding quality is easy to control, repairing welding rate is greatly reduced, product precision is improved, production hours are shortened, production efficiency is improved, and production cost is reduced.
Description
Technical field
The utility model belongs to automobile exhaust system assembly field, particularly a kind of automobile exhaust pipe that makes things convenient for the sensor installation seat.
Background technique
Present normally used sensor holder directly cooperates with pipe and welds, and it is not firm in welding process, to exist sensor holder to cooperate with pipe, and the gap is big; Influence welding quality, causing welding back repair welding rate increases, and increases man-hour; Influence manufacturing efficiency, increase cost of production.
Therefore,, reality is sought after a kind of plane welded structure that can overcome the above problems in producing.
The model utility content
The purpose of the utility model provides a kind of automobile exhaust pipe that makes things convenient for the sensor installation seat, and this outlet pipe and sensor holder adopt the plane to connect, and has solved in the past sensor holder and has cooperated not firmly with managing, and the gap is big, problem of low quality.
The technological scheme that adopts is:
A kind of automobile exhaust pipe that makes things convenient for the sensor installation seat comprises adpting flange, left down tube, bottom right administration-management, gathers pipe, catalyst converter and outlet pipe.
Two holes of adpting flange respectively with the welding of an end of left down tube one end and bottom right administration-management.
The other end of left side down tube and the other end of bottom right administration-management weld and interconnect with an end that gathers pipe simultaneously.The two ends of catalyst converter respectively with the welding of an end of the other end that gathers pipe and outlet pipe.
Its technological points is:
The circumference of outlet pipe is provided with a connection plane, and the bottom is that the sensor holder on plane is welded on the described connection plane.
Described plane is for dashing flat processing, and the plane connection can solve and in welding process, have the problem that influences welding quality.
Its advantage is:
The utility model cooperates closely through utilizing the plane, and gapless advantage has solved the big difficult problem of matching gap between original two shaped faces; It is more convenient to make two parts install, and is easier to welding, and welding quality is easier to control; Reduce the repair welding rate greatly, improved the product precision, shortened production man-hour; Improve manufacturing efficiency, reduced cost of production.
