Assembly tool and assembly method of circlip for hole

Abstract

The invention discloses an assembly tool and assembly method of a circlip for a hole. The tool comprises a guide column and a press fitting rod, the longitudinal section of the guide column is in a U type, the press fitting rod is provided with an annular boss, a through hole is formed in the center of the guide column, the guide column is inverted so that the U-type opening can be downward, the press fitting rod is sleeved with the guide column, the annular boss is in butt joint of the inner bottom wall of the guide column, the diameter of the annular boss is slightly smaller than the diameter of a workpiece hole of the to-be-installed circlip for the hole, and the diameter of the lower end of the press fitting rod is smaller than the aperture of the to-be-installed circlip for the hole. The invention further discloses an assembly method using the assembly tool. The assembly tool has the advantages that a guide sleeve serves as a limiting device, the circlip is pushed by the press fitting rod to overcome axial force to be assembled in a workpiece, the circlip is stable to move, the assembly tool is simple in structure and can be automatically controlled, a special circlip installation machine is not needed, cost is reduced, use is convenient, the assembly process is convenient and easy, and remodeling is quick.

Description

technical field [0001] The invention relates to an assembly tool for an elastic retaining ring for a hole and an assembly method thereof. Background technique [0002] The circlip is also called a circlip or a buckle, which is a kind of fastener. It is installed in the shaft groove or hole groove of the machine and equipment, and plays a role in preventing the axial movement of the parts on the shaft or the hole. Due to the diversity of the environment in which the retaining ring is used, it is difficult to assemble it in some special cases. For example, it is necessary to overcome a huge axial force during installation. The traditional assembly tool snap ring pliers cannot complete the assembly, and the cost of using a special retaining ring installation machine High, it is inconvenient to change models. Contents of the invention [0003] Purpose of the invention: In view of the above problems, the first purpose of the present invention is to provide an assembly tool for...
