Ordinary taper pin removal special tools

Abstract

The invention provides a special-purpose tool for detaching common tapered cotters. The special-purpose tool for detaching the common tapered cotters comprises a guiding seat and a punch, wherein the punch is placed in the guiding seat; an elastic strap and a hook are respectively arranged at the outer end of the guiding seat respectively; a fastening ring and a balancing weight are arranged at the tail end of the elastic strap; at least one guiding retaining groove is formed in the inner wall of the guiding seat; and a guiding retaining block which corresponds to the guiding retaining groove is arranged on the outer wall of the punch. The special-purpose tool for detaching the common tapered cotters has the advantages that impacting accuracy is high, a punching bar cannot slip from the tapered cotters and can be fixed automatically, the tapered cotters cannot be punched away, and the special-purpose tool is convenient to use and high in flexibility.

Description

technical field [0001] The invention relates to a mechanical dismantling tool, in particular to a special tool for dismantling a common tapered pin. Background technique [0002] During the operation of mechanical equipment, in order to ensure the orderly operation of each actuator, each actuator has its own phase value set. These phase values ​​are achieved by adjusting the relative positions of transmission parts such as gears, cams and sheaves in the transmission system and the shaft. In order to keep these adjusted phase values ​​well, tapered pins are often used in the prior art. position. This conical pin positioning technology is especially used in GD cigarette packaging units. It has the advantages of convenient installation, high positioning accuracy, stable and reliable operation, etc. However, it is difficult to take out because the conical pin has a self-pinning function during disassembly. [0003] The currently used taper pins include common taper pins, inter...

AI Technical Summary

Problems solved by technology

However, the two ends of ordinary conical pins are hemispherical, and there is no point of force to pull them out. The only way to disassemble them is to use a hand hammer and a punching rod to forcibly punch out from the small end to the large end.

During the disassembly process, the small head of the taper pin often occurs impact deformation due to the misalignment of the punch and the pin; the punch slips off the taper pin and causes damage; , have not yet found a common taper pin removal tool that can better solve these problems
