Device for automatically detecting air impermeability of automobile warm air radiator

Abstract

The invention relates to a device for automatically detecting the air impermeability of an automobile warm air radiator. The device is characterized by comprising a bottom plate and a group mounted onthe bottom plate and including a product positioning unit, a sealing cylinder, an inflating cylinder, a seal cylinder and an air pressure controller, wherein the product positioning unit includes anupper positioning plate, a lower positioning plate and a side positioning plate; a warm air radiator is mounted in the product positioning unit; the cylinder rod end portion of the sealing cylinder isfixedly connected with a sealing block; the sealing block is press-fitted to the cold water chamber pipe joint or the hot water chamber pipe joint of the warm air radiator; the inflating cylinder isconnected to the hot water chamber pipe joint or the cold water chamber pipe joint of the warm air radiator; one end of the air pressure controller is connected to the inflating cylinder; the other end of the air pressure controller is connected to the stamp cylinder; and the cylinder rod end portion of the stamp cylinder is connected with a stamp. The device is scientific and reasonable in design, can automatically detect the air impermeability of the warm air radiator, ensures detection efficiency and quality, saves manpower and improves work efficiency.

Description

technical field [0001] The invention belongs to the field of automobile equipment manufacturing, relates to a warm air radiator, in particular to an automatic air tightness detection device for an automobile warm air radiator. Background technique [0002] Car heater radiator is an important part of auto parts, used to protect the car engine, avoiding its heating during driving or damage caused by excessive external temperature, affecting the normal driving of the car and causing danger. The car heater radiator is mainly composed of a core body, a water inlet chamber and a water outlet chamber. The side is riveted to fix. The car heater radiators that have been riveted and fixed must be inspected for air tightness before they leave the factory for sale, and they can only be sold after the air tightness inspection is qualified and labeled. [0003] Existing air tightness detection operations are all completed by manual operation. The operator connects the warm air radiator...

AI Technical Summary

Problems solved by technology

Due to the large number of products in the production workshop, manual inspection is time-consuming and labor-intensive, and the detection efficiency is limited, so the detection efficiency cannot be guaranteed; and the phenomenon of labeling may be detected during the manual inspection process but not for verification, which is prone to problems in the later factory inspection. It also needs to be reworked again, which cannot guarantee the quality of the factory products
