Automobile air conditioner HVAC part oiling equipment

Technical Field

The invention relates to an oiling device, in particular to an oiling device for HVAC (heating ventilation air conditioning) parts of an automobile air conditioner.

Background

HVAC is an English acronym for Heating, Ventilation and Air Conditioning, namely Heating Ventilation and Air Conditioning. HVAC parts are widely applied to automobile air conditioners, when the air conditioners are assembled on a production line, oil coating operation needs to be carried out on parts of the HVAC parts, particularly oil coating treatment needs to be carried out on HVAC core parts such as air conditioner motor rotors and air conditioner controllers, and abrasion of the air conditioner motor rotors and the controllers in the operation process is reduced.

In the prior art, the oiling of the HVAC parts of the automobile air conditioner is generally completed manually, but the manual oiling has the following defects:

(1) a large amount of manual labor is needed, so that the cost expenditure of an oiling working section is greatly increased;

(2) the surface of HVAC parts is complicated, and a plurality of parts which are easy to be ignored exist, so that the oiling position of workers is not accurate enough, and the oiling is not uniform enough.

To the shortcoming of manual oiling, some automatic oiling devices have appeared on the market, for example, the publication number is: CN204134824U, the chinese patent application discloses an automatic oiling tool for an air conditioner controller, which comprises an electromagnetic valve, an oil storage tank and an oiling piece, wherein the electromagnetic valve is electrically connected with an external power supply and has a first air inlet and a first air outlet; the oil storage tank is provided with a second air inlet and a first oil outlet, and the second air inlet is communicated with a first air outlet of the electromagnetic valve through an air guide pipe; the oiling piece is provided with an oil inlet and a second oil outlet, the oil inlet is communicated with the first oil outlet of the oil storage tank through an oil guide pipe, and the second oil outlet is arranged opposite to a product to be oiled. The automatic oiling tool can automatically oil the air conditioner controller under the control of the power supply, and manual coating is not needed as in the prior art, so that a large amount of labor force is saved, and the cost expenditure of an oiling section is reduced; on the other hand, the oiling piece of this automatic oiling frock can design according to specific air conditioner controller for the oiling position on air conditioner controller surface is more accurate, the fat liquoring is more even, has also overcome the neglected coating problem that exists among the prior art, but the device can only carry out automatic oiling to air conditioner controller, and is not applicable to other HVAC parts.

For another example: the Chinese patent application with the publication number of CN204052015U discloses an unpowered automatic oiling device for a ball bearing of a motor rotor, which comprises an oiling inclined frame, an oiling track arranged on an upper groove of the oiling inclined frame and on two sides of the groove, an asphalt felt arranged in the oiling track, and a stop plate arranged at the tail end of the oiling inclined frame. The fat liquoring track slope sets up, when giving ball bearing fat liquoring, and ball bearing can roll the lower extreme from fat liquoring track upper end automatically because the action of gravity, need not external force, realizes automatic fat liquoring, has solved the trouble of traditional fat liquoring with the artifical fat liquoring of oil brush, and the fat liquoring is even, efficient. But the device can only oil the ball bearing of the motor rotor, is not suitable for other HVAC parts, and has low adaptability.
