Tool for disassembling and assembling shaft pins

Abstract

The invention discloses a tool for disassembling and assembling shaft pins. The tool comprises shaft pin disassembling pliers and shaft pin assembling pliers, wherein the shaft pin disassembling pliers and the shaft pin assembling pliers in the tool comprise pliers bodies and handles which are hinged with the pliers bodies; a through guide hole is formed in a head of each pliers body; a pushing rod is in clearance fit with the interior of the guide hole; one end of the pushing rod is hinged with the head of each handle; a through hole of which an opening is outward and into which a shaft of ashaft pin to be disassembled is inserted is formed in the head of the pliers body; clamping grooves into which two extension ends of two shaft pins to be disassembled are clamped or from which the two extension ends extend are formed at the outer end of the through hole; internal bottom walls of the two clamping grooves are flushed with internal walls of the guide holes; and when the handles are completely pressed down, end faces of free ends of the pushing rods are positioned outside the internal walls, away from the free ends of the pushing rods, of the through holes, or the end faces of the free ends of the pushing rods are flush with the internal walls of the clamping grooves which are adjacent to the free ends of the pushing rods.

Description

technical field [0001] The invention relates to the technical field of hand tools, in particular to a tool for disassembling and assembling shaft pins. Background technique [0002] At present, the commonly used tool for removing the shaft pin is to use a hammer and a thimble to align the thimble with the shaft pin through visual inspection, and then use a hammer to knock the thimble to remove the shaft pin from the shaft pin hole. It is very inconvenient to use this method to remove the shaft pin, and the shaft pin cannot be removed quickly, and it is easy to accidentally injure other parts when hitting the thimble with a hammer, and the removed shaft pin is easy to jump to the equipment when the hammer hits it It is not easy to take out the inside, and even falls in other places that are not easy to find, resulting in a waste of shaft pins. [0003] The commonly used tool for installing the shaft pin is mainly a hammer. First, place one end of the shaft pin in the shaft p...

AI Technical Summary

Problems solved by technology

Using this method to install the shaft pin is extremely inconvenient and the installation speed is slow. If the position of the shaft pin installation hole is in a small installation space, then it is impossible to use a hammer to strike; and it is easy to accidentally injure the shaft pin when hitting the shaft pin with a hammer To other parts, use a hammer to hit the installation shaft pin, it is easy to make the position of the shaft shift or loosen, thus affecting the installation accuracy of the shaft
