In order to reduce weight, the piston pin is generally made of high-quality alloy steel and is hollow, the piston pin is formed by general high-coaxiality extrusion, the coaxiality of a piston pin hole is about 0.05mm, so that the precision of a product can be improved, the rotating inertia of the product during working is reduced, however, a connecting rod is installed in a cylindrical inner hole during use, the connecting rod moves back and forth during working, more lubricating oil cannot be arranged in the existing pin body structure, the damage to the inner wall of the piston pin is easy to cause, in the movement process of the connecting assembly, the lubricating property in the movement process cannot be guaranteed, the piston pin cannot guarantee continuous lubrication, if the movement of the connecting structure is too dry, the service life of the piston pin is also easy to influence, and even the locking phenomenon can occur.
SUMMERY OF THE UTILITY MODEL
The utility model aims to provide a taper hole piston pin formed by ultrahigh-coaxiality extrusion, which is used for overcoming the problems in the prior art.
The technical scheme of the utility model is as follows: the novel oil-saving pin comprises a pin body, a plurality of oil holes are distributed in the inner annular of the side wall of the pin body at equal intervals, a central groove matched with the pin body is formed between every two oil holes, an oil storage plug matched with the central groove is arranged in the central groove, one side, far away from the central groove, of each oil hole is provided with a sealing ring matched with the pin body, and a functional connecting block is arranged between each sealing ring and each oil hole.
The function connecting block is of a triangular structure, and an included angle between the function connecting block and the inner wall of the pin body is 45 degrees.
And auxiliary holes are formed in the two sides of the oil storage plug.
The inside of oilhole is equipped with a plurality of evenly distributed's enhancement function board, the inside of strengthening the function board is equipped with a plurality of evenly distributed's functional hole.
The utility model has the beneficial effects that: the pin body structure of utilization that can be fine, for coupling assembling is at the motion in-process, provide abundant lubrication, can realize reasonable oil storage space, retrieve and release fluid, when can guaranteeing connection structure motion in-process lubricity, make the fluid of saving more balanced in the storage space, let the piston pin use more stable, and can guarantee continuous trace seepage, let lubricated effect fill longer time, thereby make equipment nimble more and practical.
