Description

Piston ring mounting device of the engine

The present invention relates to a piston ring mounting device for an engine, and more particularly, to a piston ring mounting device for an engine to automatically supply, feed and mount the piston ring.

The engine generating the driving force for driving the vehicle is composed of a structure that is coupled to the piston reciprocating linearly to the bore formed in the cylinder block.

The linear reciprocating force of the piston is converted to the rotational force driving the crankshaft by the connecting rod, and thus the volume of the combustion chamber in communication with the bore in the cylinder block and the cylinder head coupled thereto is required to make the piston reciprocate. It is only.

That is, the mixer is a mixture of air and fuel is supplied to the combustion chamber, and the mixer is combusted and exploded so that the piston is linearly moved in accordance with the volume change of the combustion chamber to operate the engine to drive the vehicle.

On the other hand, the piston is sliding from the cylinder block 2 in the state where the sealing is made as shown in Figs. 1 and 2, in order to seal the piston 4, the outer periphery of the head of the piston 4 A plurality of ring grooves 6, 8, 10 are interposed between the lands, and rings 12 are mounted on the ring grooves 6, 8, 10, respectively.

In addition, such a plurality of rings 12 are composed of a gas ring disposed on the top of the piston 4 and a plurality of oil rings disposed below the gas ring, so that the gas ring causes the gas in the combustion chamber to pass through the piston 4. And leaking between the walls of the cylinder block 2, and scraping off lubricating oil from the bore walls of the cylinder block 2 with a plurality of oil rings.

In addition, the plurality of rings 12 are formed in a shape in which one side is cut so that the plurality of rings 12 may be mounted in the ring grooves 6, 8, and 10 of the piston 4. Holes 14 and 16 are drilled into the holes 14 and 16 to be opened by the jig 18 as shown in FIG. 8) It is mounted by resiliently recovering the circle at the position of 10.

However, as described above, since the piston ring is conventionally mounted on the piston by manual operation using a predetermined jig, it is not only cumbersome and difficult to install the piston ring, but also requires a long working time, which is a factor of lowering productivity. There was this.

The present invention has been devised to solve the above-mentioned disadvantages, and the object of the present invention is not only to make the piston ring piston work simple and convenient, but also to improve productivity by reducing the working time. It is to provide a piston ring mounting device for an engine.
