Problems solved by technology

At present, when the elastic retaining ring is manually adjusted and installed, the operator needs to open the opening of the nut assembly to install the elastic retaining ring into the installation groove of the elastic retaining ring. The opening is further reduced to prevent the retaining ring from loosening. Because the size of the elastic retaining ring is too small, it often requires multiple adjustments to install it, which is time-consuming and laborious to install.
At the same time, when the elastic retaining ring is manually expanded, the deformation of the retaining ring is irregular, and the local force concentration is prone to plastic deformation, which makes the entire circumferential plane of the retaining ring unable to be even, which in turn leads to the assembly of the retaining ring not being fully in place or easy to loosen and fail problems, may cause rework, and even affect the use of pallet components

Abstract

The invention relates to a tool for pressing a split elastic washer into a bolt, and is applied in the technical field of mechanical assembly process equipment. The elastic washer pressing tool comprises an elastic washer sleeve, and further comprises a pressure transmission sleeve, wherein the pressure transmission sleeve is a cylindrical structure with an opening at the bottom and sleeves the outer surface of the elastic washer sleeve, the lower portion of the elastic washer sleeve is provided with an opening limiting groove for limiting placement of the elastic washer, the bottom of the elastic washer sleeve is in a trumpet shape, a diameter of the bottom is larger than an outer diameter of a bolt to be installed, the top of the pressure transmission sleeve serves as a pressing portion,and is spaced from the top of the pressure transmission sleeve by a distance, an inner diameter of the bottom of the pressure transmission sleeve is not larger than an outer diameter of the elastic washer, and the bottom abuts against the upper surface of the elastic washer. The tool has the following advantages that 1, it is guaranteed that the elastic washer is uniformly expanded along a wholecircular plane, and the mounting quality of the elastic washer is improved; and 2, the structure is simple, and use is convenient.

Description

technical field [0001] The invention relates to a tool for pressing an open elastic retaining ring into a bolt, which is applied in the technical field of mechanical assembly process equipment. Background technique [0002] During the installation process of the four-thread cylindrical nut assembly, a circlip needs to be installed on the nut assembly first, and when the circlip is installed in the circlip installation groove of the nut assembly, the opening size of the circlip needs to be enlarged to A certain size can be installed in it. At present, when the elastic retaining ring is manually adjusted and installed, the operator needs to open the opening of the nut assembly to install the elastic retaining ring into the installation groove of the elastic retaining ring. The opening is further reduced to prevent the retaining ring from loosening. Because the size of the retaining ring is too small, it often requires multiple adjustments to install it, and the installation i...
