Abstract

The invention provides a cotter splitting tool. The tool comprises a body, a positioning pillar arranged on the body and used for installing a cotter to be split, and a splitting part movably arranged on the body close to or away from the positioning pillar. The tool comprises the body and the positioning pillar and the splitting part installed on the body, and due to the fact that the splitting part is movably arranged close to or away from the positioning pillar and the cotter is installed on the positioning pillar and open towards the splitting part, the cotter can be split after being moved towards the positioning pillar, and the side wall of the cotter can be bent by swinging the splitting part. The tool is simple in structure and convenient to operate, the cotter can be split quite conveniently, and cotter splitting efficiency is improved.

Description

technical field [0001] The invention relates to the field of component fastening, in particular to a cotter pin splitting tool. Background technique [0002] At present, cotter pins are used in many parts of the EMU bogie to prevent loosening. Most of the cotter pins are installed at the lower part of the bogie. When splitting and bending the cotter pins, it is necessary to perform operations at the lower part of the bogie. Due to the small working space, the operator cannot operate Inconvenient, low efficiency and affect the cotter pin bending effect. [0003] In addition, cotter pin splitting is a common fitter operation in the assembly process. At present, there is no general operating tool, and hammers and flat chisels are commonly used for splitting. This splitting method has low splitting efficiency. Contents of the invention [0004] The main purpose of the present invention is to provide a cotter pin splitting tool to solve the problem of low efficiency in the pri...
