Background
The piston ring is used for imbedding the inside becket of piston slot, and the piston ring divide into two kinds: a compression ring and an oil ring. The compression ring can be used for sealing the combustible mixed gas in the combustion chamber; the oil ring is used to scrape off the excessive oil on the cylinder. The piston ring is a metal elastic ring having a large outward expansion deformation, which is fitted into a ring groove having a cross section corresponding thereto. The reciprocating and rotating piston rings form a seal between the outer circumferential surface of the ring and the cylinder and one side of the ring and the ring groove by means of a pressure difference of gas or liquid.
In the process of installing a piston, the piston ring must be opened to a certain degree before being installed in the piston so as to be smoothly installed in the piston ring groove. The installation method has low working efficiency and high labor intensity of workers, and simultaneously, because the hand strength is difficult to control, the piston ring is particularly easy to strain or break, and the installation method has long installation time and low efficiency. Therefore, the market has an auxiliary quick installation device, for example, a piston ring quick replacement device provided with the publication number of CN206306072U, is convenient to install and even in stress, prevents the piston ring from being broken and damaged, but the piston ring is sleeved on the cylinder body, the piston ring needs to be slid by hand to the large end of the diameter to be propped open, the stress is uneven, the piston ring is easy to skew, the sliding speed is reduced, and the installation efficiency is influenced.
Therefore, we propose a hand-press type piston ring installation device based on force action, and a worker can realize the installation of the piston ring to the piston by slightly pressing the piston ring by using the device, and finds the most appropriate size of the piston ring to the piston. The installation equipment of the traditional piston ring is avoided, when the installation equipment is installed, the piston ring is usually broken to the maximum, then the piston ring is sleeved on the piston, the stress is uneven, and the damage to the piston ring is extremely easy to cause.
