[0002] The interior of the automotive air-conditioning pipeline needs to bear a certain pressure, which is generally 0.8-1.2MP. The existing air-conditioning manufacturers have no effective way to improve the riveting method of the aluminum sleeve and the rubber hose. At present, there are mainly The following problems: one is that the riveting is not tight when the aluminum sleeve is riveted, and the aluminum sleeve is loose, which affects the product quality. The phenomenon of dialing out will affect the quality of the product, which will cause the car air conditioner compressor to not work normally

Embodiment Construction
[0015] Attached below figure 1 An embodiment of the present invention is described.
[0016] A riveting structure for automobile air-conditioning pipes with helical teeth, which has a joint body 5, the joint body 5 is tubular, the joint body tail 1 of the joint body 5 is sleeved with the rubber hose 2 of the automobile air-conditioning pipeline, and the joint body tail 1 is It is made with helical teeth 3, and the rubber hose 2 is set on the helical teeth 3 of the tail part 1 of the joint body. The outer surface of the rubber hose 2 is covered with a fastener 4, the fastener 4 is an aluminum sleeve, and the fastener 4 connects the rubber hose 2 It is connected by riveting with the tail part 1 of the joint body.
[0017] Also provided is a riveting method for a riveting structure of an automotive air-conditioning pipe with helical teeth, comprising the following steps:
[0018] 1) Use gear hobbing equipment to hob the tail of the joint body to form teeth;
[0019] 2) Stamp t...

The invention provides a riveting structure of an automobile air-conditioning pipe with inclined teeth and a riveting method of the riveting structure. The riveting structure is provided with a connector body, wherein a connector body tail part of the connector body is sleeved with a rubber pipe of the automobile air-conditioning pipe into a whole body; teeth are arranged on the connector body tail part and the rubber pipe is sleeved on the teeth of the connector body tail part; a fastening piece is sleeved on the outer surface of the rubber pipe; and the fastening piece is used for tightly connecting the rubber pipe with the connector body tail part. Inclined teeth are arranged on the connector body tail part so that the rubber pipe can be more smoothly sleeved on the connector body tail part and is not easy to pull out in an opposite direction; when the rubber pipe is sleeved, the time and the labor are saved; and the firmness in connecting the rubber pipe with the connector body is increased and the practical value is higher.
Description
technical field [0001] The invention relates to the field of riveting rubber hoses of automobile air-conditioning pipelines, in particular to an automobile air-conditioning pipe riveting structure with helical teeth and a riveting method thereof.
