Abstract

The utility model discloses a rubber pipe riveting structure of an air-condition pipeline, which is characterized in that the outer wall of the end part of an aluminum pipe is equipped with ring-form hobbings uniformly distributed in parallel, an aluminum cover is sleeved outside the end part of the aluminum pipe, one end of the aluminum cover forms a ring-form riveting face with the outer wall of the aluminum pipe, an interval is formed between the outer wall of the aluminum pipe and the inner wall of the aluminum cover, so the aluminum cover and a cup joint body of the aluminum pipe form a ring-form opening relative to the other end of the ring-form riveting face, the rubber pipe is inserted into the interval from the ring-form opening, the end of the rubber pipe is resisted against the inner side of the ring-form riveting face, the aluminum cover is equipped with a ring-form rolling groove, and the bottom of the ring-form rolling groove is resisted against the rubber pipe in the interval. The product can improve the riveting efficiency of the hobbings and the rubber pipe in the process of rubber pipe riveting by improving the machining process and the goals of improving production efficiency and product quality and saving cost are reached. The rubber pipe riveted structure has the advantages of greatly increasing the production efficiency and the product quality, reducing the machining difficulty, reducing the cost and increasing the firmness of the rubber pipe and the pipeline.

Description

A kind of rubber pipe riveted structure of air-conditioner pipeline

Technical field

The utility model relates to the technical field of car air conditioner pipeline, a kind of specifically rubber pipe riveted structure of air-conditioner pipeline, particularly its mechanical connecting structure.

Background technique

Each car air conditioner factory commercial city does not have effective way to improve aluminium cover riveted and sebific duct technique for riveting at present, all kinds of corrupt practices creep in to must know existing technology, as: 1. be easy to generate the not tight phenomenon of riveted when aluminium overlaps riveted, the aluminium cover produces loosening, influences quality of product; 2. the short pipe of straightway is damaged by mould when aluminium cover riveted easily, influences quality of product; 3. sebific duct is difficult to be inserted into the end when the sebific duct riveted, can cause riveting not press tightly, and the phenomenon that sebific duct is extracted easily influences quality of product.

Because the defective of above-mentioned technology, so still need existing rubber pipe riveted structure of air-conditioner pipeline and technique for riveting are further improved.

Summary of the invention

The purpose of this utility model is to provide a kind of rubber pipe riveted structure of air-conditioner pipeline, its aluminum pipe end portion is furnished with the subtriangular annular gear hobbing in cross section, has guide effect, after aluminium overlaps twice riveted and slot rolling, can play good positioning and locking effect, overcome the shortcoming and defect that exists in the prior art the sebific duct of inside.

To achieve these goals, the technical solution of the utility model is: a kind of rubber pipe riveted structure of air-conditioner pipeline, it mainly comprises aluminum pipe, it is characterized in that: described aluminum pipe end outer wall is provided with the annular gear hobbing of even parallel distribution, be socketed with the aluminium cover outside the aluminum pipe end, aluminium overlaps an end and the aluminum pipe outer wall forms ring-type riveted face, form the gap between aluminum pipe outer wall and the aluminium cover inwall, so aluminium cover and aluminium tube sleeve junctor form annular opening with respect to the other end of ring-type riveted face, sebific duct inserts in the gap from annular opening, and the end of sebific duct props up the inboard of ring-type riveted face, and aluminium cover place is provided with the ring-type slot rolling, and the bottom land of ring-type slot rolling props up the sebific duct in the gap.

The utility model discloses a kind of rubber pipe riveted structure of air-conditioner pipeline, enhance productivity by can in sebific duct riveted process, having improved the efficient of gear hobbing and sebific duct riveted to the improvement of processing technology, having reached, the purpose of quality of product and saving cost.Advantage of the present utility model is to enhance productivity greatly, quality of product; Reduce difficulty of processing; Reduce cost; Improve the soundness of sebific duct and pipeline.Have outstanding substantive distinguishing features and remarkable progress compared to existing technologies.

Embodiment

With reference to the accompanying drawings, the utility model further is described.

The utility model is a kind of rubber pipe riveted structure of air-conditioner pipeline, as shown in Figure 1, it mainly comprises aluminum pipe 1, it is characterized in that: described aluminum pipe 1 end outer wall is provided with the annular gear hobbing 2 of even parallel distribution, be socketed with aluminium cover 3 outside aluminum pipe 1 end, aluminium overlaps 3 one ends and aluminum pipe 1 outer wall forms ring-type riveted face 4, aluminum pipe 1 outer wall and aluminium overlap between 3 inwalls and form the gap, so aluminium cover 3 and aluminum pipe 1 belled body form annular opening with respect to the other end of ring-type riveted face 4, sebific duct 5 inserts in the gap from annular opening, and the end of sebific duct 5 props up the inboard of ring-type riveted face 4, and aluminium overlaps 3 places and is provided with ring-type slot rolling 6, and the bottom land of ring-type slot rolling 6 props up the sebific duct 5 in the gap.

In the specific implementation, the cross section of described annular gear hobbing 2 shape triangular in shape, leg-of-mutton inclined-plane is to same direction setting, leg-of-mutton inclined-plane distributes to the annular opening direction, so just, form the mixed tooth of pagoda shape in aluminum tube surfaces, when assembling, sebific duct has guide effect, can guarantee that sebific duct can be inserted into the bottom along the elevation angle, annular gear hobbing inclined-plane when inserting, behind aluminium cover riveted slot rolling, can play limit effect to sebific duct, on the grasp of aluminium cover and sebific duct, be greatly improved behind the riveted, two ends loosening phenomenon can not occur during with tensile test bigger before yet, have external force that aluminium is with can better to guarantee under the situation of vibratory impulse the soundness that connects in addition yet.

It is 2mm-4mm that described aluminium overlaps the distance that 3 places are provided with between 6, two ring-type slot rollings 6 of two ring-type slot rollings.

Present embodiment adds the special-purpose gear hobbing equipment and mold of elder generation's use in man-hour, and gear hobbing shaping processing is carried out at pipeline end end.With aluminium cover riveting die aluminium is overlapped riveted on pipeline again, subsequently sebific duct is inserted into aluminium cover inner bottom part, with sebific duct riveted equipment and specialized mould it is carried out riveted again.

Rubber pipe riveted structure of air-conditioner pipeline described in the utility model has passed through popular (TL82316) test standard, GM (GMW14319), Volvo (TR-31803942), Scania multinomial sebific duct riveted assembly test standards such as (TB4040).

Above content be in conjunction with concrete preferred implementation to further describing that the utility model is done, can not assert that the utility model is concrete to implement to be confined to above-mentioned these explanations.For the utility model person of an ordinary skill in the technical field, under the prerequisite that does not break away from the utility model design, can also make some simple deduction or replace, all should be considered as belonging to protection domain of the present utility model.
