Abstract
The utility model discloses an improved piston comprising a piston body and a locating nut. A screw hole is formed on one side hanging the piston body, the locating nut is screwed in the screw hole to fixedly connect with the piston body, and a central hole matching with a grinder centre is formed in the locating nut. The improved piston is simple in structure, convenient to operate, and is capable of guaranteeing processing accuracy of the piston, prolonging service life of the piston, simplifying process and saving production cost.
Description
Technical field
The utility model belongs to engineering mechanical device, and concrete is a kind of follow-on piston.
Background technique
Piston is engineering machinery application parts quite widely, and piston belongs to axis products, needs grinding machine fine grinding after heat treatment, tratitional technology is after having ground center hole, could adopt Double Tops pin to hold out against, and then carries out grinding, this method has increased procedure, has reduced manufacturing efficiency; Center hole owing to cannot guaranteeing the precision of its circularity, will directly affect the degree of finish, tapering, concentricity, ovality of piston etc. when grinding during upper grinding machine fine grinding, do not guarantee the quality of piston, has reduced working life.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of follow-on piston, and the precision while guaranteeing Piston Machining improves piston working life, has simplified operation simultaneously, has saved cost of production.
For solving the problems of the technologies described above, the utility model provides a kind of follow-on piston, it comprises piston only and setscrew nut, at piston only, lift a side and open bolt hole, setscrew nut screws in bolt hole and is fixedly connected with piston only, and described setscrew nut has the center hole suitable with grinding machine thimble.
Described piston only oil guide slot is circular-arc, when piston moves in cylinder body, is difficult for pulling cylinder body, has improved oil storage performance simultaneously.
The utility model is simple in structure, easy to operate, and the precision while having guaranteed Piston Machining has improved piston working life, has simplified operation simultaneously, has saved cost of production.
