Problems solved by technology

However, due to the high-speed movement of the piston ring, and the smooth outer surface of the circumference, there is no function of storing lubricating oil, so the phenomenon of melting and wear often occurs, which reduces the elasticity of the piston ring, shortens the service life of the piston ring, and affects the accessories. Wear of the inner wall of the cylinder liner

Embodiment Construction

[0006] 1. Manufacture of honing head for honing the outer circle

[0007] Traditional honing can only honing the inner hole, not the outer circle.

[0008] The reticulated honing head for honing the outer circle platform is as follows: a compression mechanism is installed on the outer side of the honing head frame, and a double T sand bar frame is installed on the inner side of the honing head frame, and sand bars are welded on the sand bar frame;

[0009] 2. Sand strip garden

[0010] Grinding sand strips with internal grinding, the size of which is 2 mm larger than the outer diameter of the piston ring;

[0011] 3. Calibrate mandrel

[0012] The coaxiality error between mandrel and honing spindle is less than 0.005mm;

[0013] 4. Chrome plating

[0014] After chrome plating, check the thickness of the chrome layer;

[0015] 5. Tissue piston ring

[0016] Set the piston ring on the mandrel, the inner diameter of the ring and the outer diameter of the mandrel form a tran...

Abstract

The invention relates to a honing technology for flat table reticulated lines at the outside surface of a piston ring, by which a honing head for honing an excircle is designed and a historical phenomenon that the honing technology only can be used for honing an inner hole but not the excircle in the world is changed. In the process of honing, a compression device at the outer part of the honing head is used for compressing honing oil at the inner part of the honing head to contact with the peripheral outside surface of the piston ring so as to form the flat table reticulated lines at the peripheral outside surface.

Description

technical field [0001] The invention relates to honing technology, in particular to a network pattern honing technology on the outer surface of a piston ring. Background technique [0002] At present, the outer surface of the piston ring is a smooth surface, and its peripheral outer surface cooperates with the cylinder inner wall to move, and can only rely on the platform texture of the cylinder inner wall to store lubricating oil to lubricate itself. However, due to the high-speed movement of the piston ring, and the smooth outer surface of the circumference, there is no function of storing lubricating oil, so the phenomenon of melting and wear often occurs, which reduces the elasticity of the piston ring, shortens the service life of the piston ring, and affects the accessories. Wear on the inner wall of the cylinder liner. Contents of the invention [0003] The purpose of the present invention is to provide a piston ring outer surface platform reticulate honing technol...
