Detailed description of the invention
Below with reference to embodiment and attached drawing, the present invention is described in detail, in which:
Fig. 1 is the structural schematic diagram of test macro in the present invention；
Fig. 2 is the lock out operation flow diagram of test macro in the present invention；
Fig. 3 is the testing process schematic diagram of test macro in the present invention.
Specific embodiment
As shown in Figure 1, the present invention proposes that test macro is suitable for air-conditioning, the outdoor unit 1 of air-conditioning is equipped with high-pressure stop valve 11
With low-pressure shutoff valve 12, pipe fitting is respectively connected on high-pressure stop valve and low-pressure shutoff valve, high-pressure stop valve is commonly referred to as small section
Only valve, low-pressure shutoff valve are commonly referred to as big shut-off valve.
Test macro includes: testboard, the first electric screwdriver 2, the second electric screwdriver 3, power supply tooling 4, docking facilities 5 and controller 6,
First electric screwdriver 2 and the second electric screwdriver 3 are connected on testboard, and the first electric screwdriver 2 is used for locking high-pressure stop valve 11, the second electric screwdriver 3
In locking low-pressure shutoff valve 12, controller control the first electric screwdriver 2 and the second electric screwdriver 3 working condition, by controller automatically according to
Secondary locking high-pressure stop valve 11 and low-pressure shutoff valve 12 are to recycle refrigerant.Power supply tooling 4 is equipped with connecting column connected to the controller,
Connecting column is used to connect with the binding post on the terminal plate 13 of outdoor unit 1, and power supply tooling 4 is also equipped with magnet, power supply work
4 are filled to be adsorbed on the terminal plate 13 of outdoor unit 1 by the magnet.Docking facilities 5 are connected on testboard, and effect is orientation room
Outer machine 1, there are two pneumatic pinch head, a pneumatic pinch heads to be used to clamp the pipe fitting of high-pressure stop valve 11 for the tool of docking facilities 5, separately
One pneumatic pinch head is used to clamp the pipe fitting of low-pressure shutoff valve 12, and the working condition of two pneumatic pinch heads is by controller control
System.
As shown in Figure 2,3, outdoor unit 1 is transported on test position corresponding with testboard by assembly line, and controller is connected with
Start button, pressing start button test macro can start to execute test, before test, the first electric screwdriver 2 is manually inserted into height
Second electric screwdriver 3 is inserted into low-pressure shutoff valve 12 by pressure cutoff valve 11, and docking facilities 5 are manually clamped high-pressure stop valve 11 and low pressure
Pipe fitting on shut-off valve 12, manually by 13 grafting of terminal plate of power supply tooling 4 and air-conditioning, power supply tooling 4 is adsorbed by magnet
It is located on terminal plate 13, start button is pressed after the completion of connection.Controller controls after the enabling signal for being connected to start button
Air-conditioning enters refrigeration mode, and controller control air-conditioning enters the operating parameter of acquisition air-conditioning after refrigeration mode, compares operating parameter
Whether in its corresponding default range of operation, if locking high-pressure stop valve and low-pressure shutoff valve successively then to recycle refrigerant,
Controller judges that air-conditioning is unqualified when operating parameter exceeds its corresponding default range of operation, and operating parameter herein can pass through
Corresponding sensor is set to obtain, or the data acquisition by reading air-conditioning mainboard, operating parameter is refrigerant pressure, electric current
Value etc..
Controller successively locks high-pressure stop valve and the process of low-pressure shutoff valve is: first starting the first electric screwdriver 2 locking high pressure
Shut-off valve 11 compares the torque of the first electric screwdriver 2 whether in the first default acceptability limit, if torque is in the first default acceptability limit
It is interior, then judge that high-pressure stop valve 11 locks qualification, controller closes the first electric screwdriver 2 when the first electric screwdriver 2 feeds back locking signal, if
It is unqualified then to judge that high-pressure stop valve 11 is locked not in the first default acceptability limit for torque；High-pressure stop valve 11 locks qualification
Afterwards, controller is when refrigerant pressure is down to pre-set low pressure value on the pipeline that low-pressure shutoff valve 12 is connected, starting the second electric screwdriver 3 lock
Tight low-pressure shutoff valve 12, compares the torque of the second electric screwdriver 3 whether in the second default acceptability limit, if torque is in the second default conjunction
Within the scope of lattice, then judge that low-pressure shutoff valve 12 locks qualification, controller closes the second electricity when the second electric screwdriver 3 feeds back locking signal
3 are criticized, if it is unqualified to judge that low-pressure shutoff valve 12 is locked not in the second default acceptability limit for torque.Controller is high in locking
Pneumatic pinch head is controlled after pressure cutoff valve 11 and low-pressure shutoff valve 12 and unclamps pipe fitting, and controller is unclamped in pneumatic pinch head manages
Feedback completes signal to assembly line when connector, and outdoor unit is transported out of test position by assembly line, the first electric screwdriver 2, the second electric screwdriver 3,
Docking facilities 5 and power supply tooling 4 are pulled out in the case where outdoor unit 1 is far from the pulling force of test position, without human intervention, improve test effect
Rate.In a preferred embodiment, the first default acceptability limit is 5.25 ± 0.25N.M, and pre-set low pressure value is 0.03Mpa, and second is pre-
If acceptability limit is 7.25 ± 0.25N.M.
Preferably, test macro further include: tip parts connected to the controller, controller are locked in high-pressure stop valve 11
Unqualified or low-pressure shutoff valve 12 lock unqualified or air-conditioning it is unqualified when control tip parts issue alarm signal, in time notify
Combined aural and visual alarm can be used in operator's handling failure, tip parts.Collected refrigerant pressure value, current value in test process
Etc. operating parameters can also save to computer, become more stable data communication, facilitate testing crew carry out science experiment
Analysis reduces the problem for the data inaccuracy that manual record process and other intermediate links occur, greatlys improve working efficiency.
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, all in essence of the invention
Made any modifications, equivalent replacements, and improvements etc., should all be included in the protection scope of the present invention within mind and principle.
