Efficient piston ring installing tool

Abstract

The invention relates to an efficient piston ring installing tool. The efficient piston ring installing tool comprises a pushing and pressing piece, a pressing block, an expansion sleeve, a lining anda piston ring. The pushing and pressing piece is composed of a cylinder face annular body and handles. The corresponding handle is fixed to each of the two sides of the cylinder face annular body. The axes of the two handles are the same straight line. A plurality of bosses arranged at equal intervals are arranged along the circumference face of the middle portion of the inner wall of the cylinder face annular body. The pressing block is a cylindrical body, and a plurality of rib plates arranged at equal intervals are formed in an extending manner in the radial direction of the cylindrical body. The outer side wall of the expansion sleeve is of a conical structure, a cylindrical cavity is formed in the middle portion of the expansion sleeve, and a plurality of sliding grooves for the pressing block and the rib plates to downwards move from one end of the expansion sleeve are formed in the wall body of the expansion sleeve in the axial direction. The lining is a cylinder. According tothe efficient piston ring installing tool, the piston ring assembling operation process is convenient and fast, and time and labor are saved; and various adverse factors during traditional assemblingare overcome, the rejection rate in the workpiece assembling process is reduced, and the assembling quality and the operation efficiency are greatly improved.

Description

technical field [0001] The invention belongs to the technical field of piston ring assembly, and in particular relates to a high-efficiency piston ring installation tool. Background technique [0002] Piston engine is an engine that converts gas pressure into rotational kinetic energy of crankshaft and main shaft. It is widely used in various power machinery, such as steam engine, diesel engine, compressor and hydraulic machine. In this type of engine parts, the piston ring has a delicate function and is installed in the piston annular sealing groove until it functions in heat conduction, guiding, sealing, and oil adjustment. The quality of its installation directly affects its sealing characteristics. If it is installed improperly, it will affect the entire engine engine performance, and even cause various engine failures. [0003] Due to the various characteristics of the piston ring structure, material and function, the assembly process often has the following characteri...

Problems solved by technology

It may even cause breakage and cracks of the workpiece, and complete sealing cannot be guaranteed in the sealing ring groove.

[0005] (2) When the piston ring is installed, the control of the expansion of the opening is particularly important. If the opening is too small, it cannot be normally installed in the sealing groove. If the opening is too large, it may exceed the design stress of the piston ring, causing the piston ring to be in danger of breaking and deforming.

[0006] (3) When assembling multi-piston rings, the piston ring assembled first will affect the subsequent piston ring assembly, and the part higher than the outer wall of the piston will interfere with the subsequent piston rings and adversely affect the assembly of the subsequent rings

[0007] (4) Piston rings are assembled in the same engine assembly process, the operation consistency is good, but the workload is large
