Piston ring grinding machine

Abstract

The invention relates to the technical field of automobile parts, in particular to a piston ring grinding machine. The piston ring grinding machine comprises a box body. Two oppositely-arranged grooves are formed in the box body, the two grooves are symmetrically formed, a sliding plate is mounted in each groove, the sliding plates are slidingly connected with the grooves, mounting plates are mounted on the upper sides of the sliding plates, two groups of oppositely-arranged roller ways are mounted on the mounting plates, each group of roller ways comprise two roller ways, and the outer sidesof the roller ways are sleeved with anti-skid sleeves. According to the piston ring grinding machine, as a first grinding device and a second grinding device are mounted on the box body, the grindingefficiency in production is enhanced, the production speed is increased, the diameters of to-be-ground piston rings applicable to the device can be adjusted by adjusting the positions of the sliding plates in the grooves, the device perfectly adapts to the piston rings with all diameters, and the universality of the grinding machine is improved.

Description

Technical field [0001] The invention relates to the technical field of auto parts, in particular to a piston ring grinder. Background technique [0002] The piston ring is a metal elastic ring with large outward expansion and deformation, and it is fitted into the section and its corresponding annular groove. The reciprocating and rotating piston ring relies on the pressure difference of gas or liquid to form a seal between the outer surface of the ring and the cylinder and one side of the ring and the ring groove. The piston ring is the core component of the fuel engine. It and the cylinder, The piston, cylinder wall, etc. together complete the fuel gas seal. [0003] When in use, the forces acting on the piston ring include gas pressure, the elastic force of the ring itself, the inertial force of the ring reciprocating motion, the friction force between the ring and the cylinder and the ring groove, as shown in the figure. Because of these forces, the ring will produce basic mo...

Problems solved by technology

[0005] The object of the present invention is to provide a kind of piston ring grinding machine, to solve the above-mentioned background technology, during production, grinding and production are often carried out through the grinding wheel, but often only one side grinding can be performed, so that the efficiency of the grinding machine is low ;In production, it is often only suitable for piston rings with a certain diameter, and cannot be compatible with all of them.
