Description

A kind of piston component in air compressor machine
Technical field
The utility model belongs to field of mechanical technique, is related to a kind of air compressor machine, the in particular to piston in a kind of air compressor machine Component.
Background technique
Air compressor machine is widely used in the links of life, especially cures as a kind of important production of energy form Medicine, food etc. are from multi-field.In air compressor machine, connecting rod is used to be converted into moving along a straight line by the rotary motion of shaft, in cylinder block Top side be equipped with cylinder body, and be equipped with piston in cylinder interior, the front end of one end of piston and connecting rod connects.Access is external Rotor will be rotated when power supply, drive the shaft rotation being inserted in rotor, then the rotary motion of shaft passes through company Bar is converted into horizontal movement, so that piston moves back and forth in cylinder interior.
The connecting rod in air compressor machine and piston are made of metal material at present, and are mainly made of aluminium, since metal is The good conductor of heat, easily compression temperature, which is conducted, leads to bearing grease failure to bearing portion and is lost, final bearing dry grinding Damage, causes complete machine that cannot use.
Summary of the invention
The purpose of this utility model is to provide a kind of high lubricating effect for the above-mentioned problems in the prior art, Piston component in air compressor machine with long service life.
The purpose of this utility model can be realized by the following technical scheme: the piston component in a kind of air compressor machine, including Piston only, connecting rod and piston pin are connected between the piston only and connecting rod by piston pin, and the piston pin is worn Connecting rod is crossed, and is provided with needle bearing between piston pin and connecting rod, which is characterized in that the middle part of the piston pin axially offers The oil storage hole being communicated with the outside, the oil storage hole is interior to be filled with lubricating oil, and the both ends of the oil storage hole are provided with anti- The only plug that lubricating oil overflows in oil storage hole, the side of the piston pin radially offer several and oil storage hole and external phase The oil outlet of connection, the oil outlet are corresponding with the position of needle bearing.
In the piston component in a kind of above-mentioned air compressor machine, pass through several between the piston pin and piston only Positioning screw is mutually fixed, several quantity locating slot identical with positioning screw is offered on the lateral wall of the piston pin, The position of several locating slots and the position of several positioning screws correspond.
Have in the piston component in a kind of above-mentioned air compressor machine, inside the piston only and to be carried for piston pin Stage portion, several described positioning screws both pass through the bottom that stage portion is resisted against several corresponding locating slots respectively.
In the piston component in a kind of above-mentioned air compressor machine, several described positioning screws and several locating slots Quantity is two.
In the piston component in a kind of above-mentioned air compressor machine, the diameter of the oil storage hole is greater than the diameter of oil outlet.
Compared with prior art, the piston component in this air compressor machine will open up storage lubricating oil inside traditional piston pin Oil storage hole, both ends are blocked with plug, and the oil outlet being connected with oil storage hole and needle bearing has been opened up in side, work as temperature Lubricating oil when degree increases in oil storage hole can be overflowed from oil outlet flow to needle bearing, so that bearing portion persistently keeps lubricating, It can also play the role of reducing temperature simultaneously, to extend the service life of piston component in air compressor machine.
