Description
Technical field
The present invention relates to compressor field, more particularly to a kind of piston rod part.
Background technology
The either refrigeration equipments such as refrigerator or refrigerator, their " heart " are a Totally-enclosed piston type compressors.And
What driving refrigerant flowed is the piston in " heart ".Piston is driven by bent axle, is existed by the transfer tape piston of the power of connecting rod
Make reciprocal linear motion in cylinder body.Due to being the compound motion in the state that swings when connecting rod works, and piston is place
In linear motion.It is existing in order to eliminate because interference of the external force in on-rectilinear movement direction brought during the swing of connecting rod to piston
Piston connect with connecting rod mainly connected with sphere.Therefore, sphere is crucial with how piston carries out preferably connecting.In mesh
It is usually stamped with two semi-circular bowl-type metals in preceding structure existing in the market, then it is welded；It is or therein
One semi-circular to be manufactured with plastic article, and another is semi-circular, is made of the more complicated extrustion of metals of shape.Therefore, nothing
By which kind of combination, although can meet to a certain extent by sphere installation to wherein, it is last the result is that：1）Installation
Compressor requirement is not achieved in precision；2）The service life of piston component is very short.It is crucial that ball centre, piston skirt body
It is and it is not good enough with the concentricity of connecting rod.The reason is that：Stamping parts is not high-precision workpiece, and stamping parts more multiple error is bigger,
Welding position more multiple error is bigger, and the accumulated error finally resulted in is also bigger.Meanwhile manufacture cost is caused to improve, installation hardly possible
It spends coefficient to increase, so as to affect the service life of compressor complete machine.
Invention content
The present invention is easy to maintenance again, service life length exactly in order to solve to have good lubricating properties, durability
Technical problem and provide it is a kind of for refrigeration compressor it is automatic fixed in piston rod part.
In order to solve the above technical problems, a kind of skill of automatic fixed middle piston rod part for refrigeration compressor of the present invention
Art solution is：
Including connecting rod and piston skirt body, connecting rod one end connection piston skirt body other end connection bent axle, the piston
The sphere pedestal that bottom end is butted on piston skirt body upper wall is installed in skirt body；The sphere pedestal includes ball seat and and ball seat
The locating ring of one；The locating ring outer diameter is less than diameter 0.05-0.1mm in piston skirt body；Ball is installed above the ball seat
Body；Bayonet is provided in the middle part of the piston skirt body；The piston skirt body its be located at that bayonet upper wall is inner to have extended downwardly buckle；It is described
Sphere upper cover is connected between sphere and buckle；Its adherent face with sphere of the ball seat is provided with oil groove；The connecting rod is provided with
Vertical oilhole；The sphere is riveted with connecting rod.
The sphere upper cover includes cover and with cover one and is connected to the Z-shaped snap-gauge of cover side；The cover
On be provided with cross recess；The cover its be located at cross recess end and be provided with card circular groove.
The oil groove is distributed for 3 and along its adherent face with sphere of ball seat etc..
What the present invention can reach has the technical effect that：Sphere of the present invention is clamped by sphere upper cover, is installed and repair side
Just, and its adherent face with sphere of ball seat is provided with oil groove and connecting rod is provided with vertical oilhole, and oil can enter perpendicular from oil groove
To oilhole, so as to reach lubricant effect, and locating ring outer diameter is less than the internal diameter of piston skirt body, can ensure ball in the positioning of sphere
The contact precision of body and concave ball surfaces and lubrication between the two, so as to improve service life.
