Quick release device for hexagon socket bolts

Abstract

The invention relates to the technical field of device disassembling and assembling, and provides an inside hexagonal bolt quick disassembling device which comprises a sleeve and a handle. One end of the sleeve serves as a force appliance end, and the other end of the sleeve serves as a fastening end. The handle is installed at the force appliance end of the sleeve. An axial hole is formed in the fastening end of the sleeve. The inside hexagonal bolt quick disassembling device further comprises a fastening structure. The fastening end of the sleeve is provided with an installation through hole and a locating structure used for fixing the fastening structure. The installation through hole extends to the inner wall of the sleeve from the outer wall of the sleeve and is perpendicular to the center line of the sleeve. The fastening structure is disposed in the installation through hole. After an inside hexagonal square hole of a back-nut bolt is broken down, the bolt can be smoothly disassembled without breaking thread connection, the completeness of a connected piece is guaranteed, and disassembling efficiency is improved. The inside hexagonal bolt quick disassembling device is mainly used for disassembling screws or bolts with cylindrical heads.

Description

technical field [0001] The invention relates to the technical field of equipment disassembly and assembly, in particular to a quick removal device for hexagon socket head bolts. Background technique [0002] The inner hexagonal back cap bolt is the main part connecting the fixed impeller and the rotor of the centrifugal air compressor. When installing and removing the inner hexagonal back cap bolt, only the inner hexagonal square hole at the end of the bolt is considered to be free from damage, deformation and corrosion. Normal disassembly of the case. When parts need to be replaced, once the force is greater and the connection is tighter, when the hexagon socket back cap bolt is removed with a hexagon wrench, due to the large torque, the hexagon hole will deform and slip, or The inner hexagonal square hole is corroded by the medium, and loses the function of cooperating with the inner hexagonal wrench and transmitting torque. At present, auxiliary tools for removing bolts...

AI Technical Summary

Problems solved by technology

This tool cannot dismantle the hexagon socket head cap bolts, nor can it dismantle the bolts with cylindrical bolt heads. Therefore, when the above situation causes the hexagon socket cap bolts to be disassembled normally, the only way to remove the connection is to use the destructive method.

However, the destructive method is easy to damage the rotor, bearing bush and other parts when removing the back cap bolts; it is easy to deform the impeller and other parts when heated by flame; it is time-consuming and laborious.

These have seriously affected the normal maintenance work and the guarantee of the maintenance period.
