Abstract

This utility model relates to the tail pipe decoration cover of a kind of acoustic filter and the mortise-tenon joint structure of outlet tail piece, belongs to the attachment structure of a kind of automobile muffler tail pipe Decorative Cover and outlet tail piece.Tail pipe decoration cover is having tenon at two, outlet tail piece and tenon correspondence position to have mortise at two, tenon and mortise junction to have 1.5 2mm width weld seams with outlet tail piece junction.Advantage is novel structure, use the mortise-tenon joint mode quickly limiting Decorative Cover radially, axially position, without Decorative Cover being positioned by fixture, due to allowance weld groove at mortise-tenon joint, have only to by weld seam slot welding completely during welding, so can also limit fusion length, fully meet design verification length requirement, control welding wire consumption simultaneously, reduce welding wire use cost, shorten weld interval, in conjunction with this 2 point, this structure has obvious advantage in terms of standardization and cost declining, also assures that position while welding endurance quality simultaneously.

Description

The tail pipe decoration cover of a kind of acoustic filter and the mortise-tenon joint structure of outlet tail piece

Technical field

This utility model belongs to the attachment structure of a kind of automobile muffler tail pipe Decorative Cover and outlet tail piece, for fast speed limit Determine Decorative Cover radially, axially position.

Background technology

Automobile engine produces harmful substance in the running, the waste gas discharged when electromotor is worked by gas extraction system and noise Carry out chemical reaction by gas extraction system, noise reduction processes, the H after being processed by tail pipe₂O、CO₂It is discharged into greatly Deng gas In gas.

Along with the continuous lifting of social development, social consciousness and aesthetics, consumer is to automobile appearance individual requirement More and more higher, different levels different industries, the aesthetic consciousness of different population also can differ widely.Along with human material's educational level Raising and the change of living environment and the variation of life style, the car as staple commodities will appear from various undoubtedly The most novel more peculiar new model of various kinds.Decorative tail tube, as the primary decoration parts of new model, should meet gas extraction system The test of energy, mates with vehicle modeling again, plays the new modeling effect that an apt word added to clinch the point, and critical role is self-evident.Wherein tail pipe dress Decorations cover on in the welding process of outlet tail piece, and owing to arc modeling is difficult to position, axial direction and radial direction need multiple Fixture is fixed, and the pinching action of fixture directly increases manufacturing cost and manufacturing man-hours.

Summary of the invention

This utility model provides the tail pipe decoration cover of a kind of acoustic filter and the mortise-tenon joint structure of outlet tail piece, to solve tail Pipe Decorative Cover is with in the welding process of outlet tail piece, and owing to arc modeling is difficult to position, axial direction and radial direction need Multiple fixtures are fixed, the problem that the pinching action of fixture directly increases manufacturing cost and manufacturing man-hours.

This utility model adopts the technical scheme that: tail pipe decoration cover is having tenon at two with outlet tail piece junction, goes out Gas tail pipe and tenon correspondence position have mortise at two, tenon and mortise junction to have 1.5-2mm width weld seam.

A kind of embodiment tail pipe decoration cover of the present utility model uses stainless steel material.

A kind of embodiment tail pipe escape pipe of the present utility model uses stainless steel material.

A kind of embodiment of the present utility model is tail pipe escape pipe thickness range 1-1.2mm.

A kind of embodiment of the present utility model is tail pipe decoration cover thickness range 0.5-1.0mm.

The utility model has the advantages that novel structure, use the mortise-tenon joint quickly limiting Decorative Cover radially, axially position Mode, it is not necessary to Decorative Cover can be positioned by fixture, due to allowance weld groove at mortise-tenon joint, have only to during welding by Weld seam slot welding completely, so can also limit fusion length, fully meets design verification length requirement, controls welding wire simultaneously and uses Amount, reduces welding wire use cost, shortens weld interval, and in conjunction with this 2 point, this structure has bright in terms of standardization and cost declining Aobvious advantage, also assures that position while welding endurance quality simultaneously.

Detailed description of the invention

Tail pipe decoration cover 1 is having tenon 101 at two, outlet tail piece 2 to have with tenon correspondence position with outlet tail piece 2 junction Mortise 201 at two, there is the wide weld seam of 1.5-2mm 3 tenon and mortise junction；

Tail pipe decoration cover uses stainless steel material SUS304；

Tail pipe escape pipe uses stainless steel material SUS304；

Tail pipe escape pipe thickness range 1-1.2mm；

Tail pipe decoration cover thickness range 0.5-1.0mm.

Operation principle: after tail pipe decoration cover is spacing with tail pipe escape pipe Tenon, is welded and fixed, makes tail pipe decoration cover positioning accurate Really, with compared with joinery and its construction Decorative Cover, save restriction axial restraint fixture, save the radially fixed fixture of restriction, pass through Tenon Weld seam slot welding connects, and defines welded seam length, in the case of equivalent material, and indefinite fusion length Decorative Cover butt welded seam length Uncontrollable, have weld seam groove Decorative Cover due at Tenon slot treatment define the length of welded seam, 100% meets design tests Card length requirement, controls welding wire consumption simultaneously, reduces welding wire use cost, shorten weld interval.
