Abstract

The invention discloses an airtight detection method and equipment for a pipe used in an automobile EGR cooler, and relates to the technical field of automobile detection. Watch the product for bubbling to determine if there is a leak problem. It includes: when the EGR cooler tube to be tested is inserted into the material feeding detection device, the clamping device makes the EGR cooler tube closely fit the material feeding detection device by applying pressure; the EGR is cooled through the intake pipe According to the air pressure sensor located in the feeding detection device, it is judged whether the air pressure in the feeding detection device is safe air pressure; if it is safe air pressure, the clamping device releases the The air pressure in the tube of the EGR cooler is used, and an airtight safety signal is sent to the automatic sorting device; when the feeding disc rotates to the discharge position corresponding to the automatic sorting device, the automatic sorting device unloading.

Description

technical field [0001] The invention relates to the technical field of automobile detection, in particular to an airtight detection method and equipment for a pipe used in an automobile EGR cooler. Background technique [0002] With the rapid development of the automobile industry, exquisite automobile manufacturing technology and stable automobile running quality are the goals pursued by every automobile assembly enterprise, which will make the automobile industry have a bright future. Among them, the EGR (Exhaust Gas Recirculation, Exhaust Gas Recirculation) cooler pipe of the automobile is an important production accessory in the automobile industry, and the airtightness of the EGR cooler pipe determines the manufacturing quality of the automobile. [0003] At present, the air tightness of the existing EGR cooler pipes is tested manually, that is, the original water inspection machine relies on artificial observation of product bubbling to determine whether there is leaka...
