Description
Technical field
The present invention relates to piston oiling technical field, particularly relate to a kind of piston oiling station.
Background technology
Piston can be largely classified into piston top, piston head and three parts of piston skirt.The Main Function of piston is subject to vapour
Combustion pressure in cylinder, and this power is passed to bent axle by piston pin and connecting rod.
Piston top is the ingredient of combustor, thus often makes different shapes, and piston of gasoline engine uses flat-top at most
Or concave crown, in order to making chamber structure compact, area of dissipation is little, and manufacturing process is simple.Piston crown is more than piston boss
Part, piston crown ring installation, to prevent high temperature, high-pressure gas from scurrying into crankcase, stop machine oil to scurry into combustor simultaneously.
All parts below piston ring groove are referred to as piston skirt.Its effect is to guide piston the most reciprocating and bear side pressure
Power.
Piston, after preliminary working, needs to carry out its surface being coated with oil processing, in order to improve its surface lubrication, pre-abrasionproof
Damage.The mode of traditional oiling is mostly artificial oiling.I.e. by the hand-held hairbrush of lubricating oil that is moistened with of staff to piston face
Carry out oiling.
Above-mentioned artificial oiling has the disadvantage that (1) oiling uniformity is not easily controlled；(2) inefficiency, not only consumes
Time, and labour intensive；(3) if hairbrush dip in lubricating oil excess, coating during, lubricating oil is easily dropped in work
On the body of personnel, the later stage is cleaned and makes troubles；(4) after the one side of piston is coated with lubricating oil, staff needs to grip
Piston scribbles the side of lubricating oil, then the opposite side of piston is carried out oiling；It is thereby possible to less because gripping friction,
And the problem gripping shakiness caused.
Summary of the invention
The present invention is directed to the deficiencies in the prior art, it is provided that a kind of piston installation is stable, firm, oiling uniform, oiling effect
The piston oiling station that rate is high.
The present invention is by the techniques below means realization above-mentioned technical problem of solution: a kind of piston oiling station, including fixed
Position mounting seat, motor, hairbrush, holding frame assembly；Described motor is arranged on the bottom of described fixed mounted seat, its output shaft and institute
