The content of the invention
For in existing evaporator air tightness detection apparatus, the detection efficiency for existing problem still not high is carried the present invention For a kind of evaporator airtight detecting apparatus solving the above problems.
What the scheme of the equipment in the present invention was realized in:A kind of evaporator airtight detecting apparatus, including detection platform, Detection platform is placed with A/C evaporator, and evaporator includes coolant inlet and outlet, including the inflation of detection platform sidepiece is examined Measurement equipment, the inflation testing equipment include gasing tank, and for inflate into coolant inlet outlet gas ducting, with And for blocking the sealing pipeline of Leng Queyechukou entrances;The inflation testing equipment also includes pressure sensor and for showing Show the pressure-display device of change value of pressure.
Principle of the invention is:By using inflation testing equipment, by coolant inlet or outlet and inflation Pipeline is connected, and sealing pipeline is closed with another mouth, is re-filled with gas, and by pressure sensor and pressure-display device Judge pressure value changes so that judge evaporator whether gas leakage.
In the present invention, as further scheme, it is additionally provided with the detection platform including fixed top board, and can be from inspection The side plate lifted in platform is surveyed, the detection platform top plate portion is additionally provided with the compressing member for compressing evaporator.Compressing member and side plate Effect be for clamping evaporator.
In the present invention, used as further scheme, the compressing member and side plate are adopted and connected by universal machine mechanism so that pressure When tight part is compressed, side plate can rise from detection platform.Compressing member and side plate are realized running simultaneously by mechanical mechanism, the machine Tool mechanism can be to be capable of achieving using existing drag link mechanism or mechanical automation equipment.
In the present invention, used as further scheme, on pedestal, the inflation is detected for the inflation testing equipment integral installation Device bottom be provided with can on pedestal left and right linear slide sliding part, by can left and right linear slide realize gas ducting and Seal the access of pipeline.
In the present invention, used as further scheme, the pressure-display device is also associated with audible-visual annunciator, and its effect is right After detection, it is found that underproof evaporator carries out sound and light alarm.
In the present invention, used as further scheme, the gas ducting and sealing pipe end are resilient flexible glue. The effect for so setting is, when gas ducting and sealing pipeline are moved to the left, it is to avoid impact damages evaporator.
In the present invention, as further scheme, marking machine is additionally provided with the inflation testing equipment, when audible-visual annunciator not During startup, marking machine carries out mark on an evaporator
Of the invention have prominent actual features and the marked improvement to be:
1. simple structure, is not required to the manufacturing process of complexity, can solve the deficiency that existing use water law detects evaporator air-tightness Part;
2. the design is unique, can be by changing some elements, it is possible to achieve the function of quick detection evaporator air-tightness.
3. the present invention increases mark function, product that can be qualified in order to after being detected to evaporator, find out air-tightness.
Brief description of the drawings
Fig. 1 is the structural representation of embodiments of the invention 1
Parts title and sequence number in figure:
Detection platform 1, evaporator 2, top board 3, side plate 4, compressing member 5, pedestal 6, inflation testing equipment 7;
Coolant inlet 2.1, cooling liquid outlet 2.2;
