Description

A kind of air conditioning for automobiles weld holes mechanism

Technical field

The utility model relates to automobile air conditioner accessories fields, and in particular to a kind of weldering of air conditioning for automobiles weld holes mechanism Connect hole.

Background technique

Automotive air-conditioning system is to realize freeze to air in a car compartment, heat, taking a breath and the device of air cleaning.It can To provide comfortably environment by bus for passenger, the fatigue strength of driver is reduced, traffic safety is improved.Air-conditioning device has become To measure whether complete one of the mark of automobile function.

Traditional air conditioning for automobiles weld hole is mostly cylinder, and usual welding hole internal diameter is 0.1- bigger than air-conditioning duct outer diameter 0.2mm.Air-conditioning connector and air-conditioning duct assembly are mostly manual assembly before welding, and Automatic manual transmission precision is inadequate, be easy to cause air-conditioning Pipeline is inserted not on earth, causes weld size bad.

Utility model content

The purpose of this utility model is that it is in view of the drawbacks of the prior art and insufficient, a kind of air conditioning for automobiles weld is provided Holes mechanism, it is transformed on the basis of original air conditioning for automobiles connector, and the welding hole transformation of its air-conditioning connector is tapered, this Design is solved very well since Automatic manual transmission precision is inadequate, and air-conditioning duct is inserted not on earth, the bad problem of caused weld size, and And possibility is provided for full-automatic unmanned welding.

To achieve the above object, the utility model is using following technical scheme: it includes plumb joint, air-conditioning duct, one Number welding hole, No. two welding holes, No.1 welding inner hole, No.1 welding exit orifice, No.1 weld hole wall, No. two welding inner holes, No. two Weld exit orifice, No. two welding hole walls；Air-conditioning duct is arranged inside plumb joint, and No.1 welding hole and No. two welding holes are respectively set In the bottom and side of plumb joint, No.1 welding hole and No. two welding holes are connected to air-conditioning duct；No.1 welding exit orifice passes through No.1 welding hole wall is connected to No.1 welding inner hole；No. two welding exit orifice are connected in No. two welding by No. two welding hole walls Hole, No. two welding inner holes are connected to air-conditioning duct by No. two welding holes.

The No.1 welding inner hole and No.1 welding exit orifice passes through a chamfering and is connected to No.1 welding hole wall.

No. two welding inner holes 41 and No. two welding exit orifice 42 are connected to No. two welding hole walls by a chamfering 43。

The diameter of the No.1 welding exit orifice 32 is 0.65mm bigger than the diameter of No.1 welding inner hole 31.

The diameter of the No.1 welding exit orifice 32 is identical as No. two welding diameters of exit orifice 42.

The No.1 welding inner hole 31 is identical as No. two welding diameters of inner hole 41, their diameter compares The big 0.1mm of the diameter of air conditioner connecting pipe.

Working principle of the utility model is: air conditioner connecting pipe is slowly reduced by welding exit orifice insertion via welding hole wall To welding inner hole various types of air conditioner connecting pipes can be accommodated to greatest extent, and can be good at because welding hole is taper Matching locking is carried out, is not interspaced.And the welding exit orifice for being greater than air conditioner connecting pipe it is inserted into trueness error require it is lower, can be with Assembly line foundry assembly is carried out by machine, saves a large amount of manpower and material resources.

After adopting the above technical scheme, the utility model has the beneficial effect that this design is solved very well due to Automatic manual transmission essence Degree not enough, insert not on earth, the bad problem of caused weld size by air-conditioning duct, and providing for full-automatic unmanned welding can Energy.
