Centrifugal ventilator disassembling tool with metal sponge aluminum shell

Abstract

The invention belongs to the field of centrifugal ventilator disassembling, and particularly relates to a centrifugal ventilator disassembling tool with a metal sponge aluminum shell. The centrifugal ventilator disassembling tool comprises a pull claw support, a rotating shaft, a fixed wrench, at least three pull claws, circular rings and a force application wrench, the pull claw support is of a sleeve structure, and an annular boss facing outwards in the radial direction is arranged at the lower end of the sleeve; the sleeve of the pull claw support sleeves the rotating shaft, outer threads of the rotating shaft are matched with inner threads of the inner wall of the sleeve, and the outer diameter of the lower end face of the rotating shaft is larger than that of the upper end face of a gear shaft; the fixed wrench is matched with the outer surface of the upper end of the sleeve to fix the pull claw support; each pull claw comprises an arc-shaped wall surface, a connecting part located at the upper end of the arc-shaped wall surface and a claw part located at the lower end of the arc-shaped wall surface, each claw part comprises a supporting part which faces inwards in the radial direction of the arc-shaped wall surface and a limiting part which faces outwards in the radial direction of the arc-shaped wall surface, and the connecting parts of the pull claws are fixedly connected with the annular boss of the pull claw support; the circular rings are arranged on the outer sides of the pull claws and located on the limiting parts of the pull claws; and the force application wrench is fixedly connected with the rotating shaft.

Description

technical field [0001] The invention belongs to the field of centrifugal ventilator disassembly, and in particular relates to a centrifugal ventilator disassembly tool with a metal sponge aluminum shell. Background technique [0002] When the original centrifugal ventilator with a metal sponge aluminum shell is disassembled, a press and a disassembly pallet are used for disassembly. When decomposing, the press exerts an instantaneous impact force, so that the centrifugal ventilator shell bears the instantaneous lifting force of the pallet. Because the shell is made of aluminum, the hardness is low, and there will be extrusion scars after the momentary force is applied to the joint with the pallet, which will affect the appearance quality of the product. Contents of the invention [0003] Purpose of the invention: to provide a centrifugal ventilator disassembly tool with a metal sponge aluminum shell, to prevent damage to the centrifugal ventilator during disassembly of the...

[0002] When the original centrifugal ventilator with a metal sponge aluminum shell is disassembled, it is decomposed using a press and a disassembly pallet. When decomposing, the press applies an instantaneous impact force, so that the centrifugal ventilator shell bears the instantaneous lifting force of the pallet. Because the shell is made of aluminum material, the hardness is low, and there will be extrusion scars after the momentary force is applied to the joint with the card board, which will affect the appearance quality of the product
