Problems solved by technology

[0006] First use the guide rod to accurately position the spring pin, and knock out the spring pin through the bottom of the round punch by tapping the nail cap. This design can not only protect the spring pin from damage, but also solve the defects that are difficult to hit during the existing knocking process.

Embodiment Construction

[0016] The accompanying drawings are for illustrative purposes only, and should not be construed as limitations on this patent; in order to better illustrate this embodiment, certain components in the accompanying drawings will be omitted, enlarged or reduced, and do not represent the size of the actual product; for those skilled in the art It is understandable that some well-known structures and descriptions thereof may be omitted in the drawings. The positional relationship described in the drawings is for illustrative purposes only, and should not be construed as a limitation on this patent.

[0017] Such as figure 1 As shown, a cylindrical spring pin removal tool includes a round punching part 2, a nail cap 1, and a guide rod 3. The top of the round punching part 2 is provided with a nail cap 1, and the knocking area is increased through the nail cap 1, so that the knocking It is easy to hit during the hitting process. There is a guide rod 3 at the bottom of the round pun...

Abstract

The invention relates to the field of mechanical tools and particularly relates to a disassembling tool of a cylindrical spring pin. The disassembling tool comprises a round punch part, wherein one end of the round punch part is provided with a guide rod, and the other end of the top of the round punch part is provided with a nail head. The spring pin is accurately located by the round punch of the tool, inner and outer pins of the spring pin are separately hit, and equipment is protected from damage. Friction between the hands and the tool is increased to prevent hand hurt caused by slip resulting from vibration during hit. By additionally arranging the nail head, the hitting area is increased, and the hitting precision in the hitting process is high.

Description

technical field [0001] The invention relates to the field of mechanical tools, more specifically, to a cylindrical spring pin removal tool. Background technique [0002] The elastic spring pin is a headless hollow cylindrical body, which is slotted in the axial direction and is generally chamfered on one side. It is used for positioning, connection, fixing, etc. between parts, and is divided into internal pins and external pins. The outer diameter of these pins is slightly larger than the mounting hole diameter. When installing, enter from the chamfered surface and knock on another non-chamfered surface; when disassembling, use a round punch to align with the chamfered surface and knock out the spring pin. Since the outer diameter of the spring pin is slightly larger than the assembly hole diameter, and this type of pin is axially slotted, if the chamfered surface is knocked biased during disassembly, it is easy to deform the spring pin, get stuck in the assembly hole, and ...
