Detailed Description

In order to make the objects, contents and advantages of the present invention clearer, the following detailed description of the embodiments of the present invention is provided.

The invention provides a disassembly and assembly mechanism of a portable belt wheel mechanism, which comprises an automatic rotating bracket 3-7 and an automatic telescopic supporting rod 3-8; the automatic rotating supports 3-8 are respectively hinged with an assembling tool and a disassembling tool; an input shaft 1-1 of the motor is in interference fit with a belt wheel 2;

the disassembling tool comprises a disassembling disc, a disassembling screwing screw 3-1 and a disassembling fixing screw 3-2, wherein the disassembling screwing screw 3-1 and the disassembling fixing screw 3-3 are arranged on the disassembling disc;

the assembling tool comprises an assembling disc 3-5, assembling tightening screws 3-4 and assembling fixing screws 3-6, wherein the assembling tightening screws 3-4 and the assembling fixing screws 3-6 are arranged on the assembling disc; the assembly disc consists of two circular discs and supports the assembly fixing screw to prevent the assembly fixing screw from being twisted off due to overlong length;

the lower part of the automatic rotating bracket is connected with an automatic telescopic supporting rod;

FIG. 2 is a schematic structural diagram of a disassembling mechanism of the present invention, and is based on the schematic structural diagram of the overall assembling mode of FIG. 1. therefore, when disassembling a belt pulley, an automatic rotating bracket 3-7 can be rotated to a disassembling tool, an automatic telescopic supporting rod 3-8 is used for adjusting the position, a disassembling fixing screw 3-2 is screwed and fixed with six circumferential screw holes of the belt pulley 2 through a disassembling disc, then a disassembling screwing screw 3-1 is slowly screwed through a central screw hole of the disassembling disc and acts on a motor input shaft, a cushion block is arranged in front of the disassembling screwing screw in order to weaken the direct acting force of the screw and the motor input shaft 1-1, the force of the disassembling screwing screw 3-1 which pushes against the cushion block to the motor input shaft will be larger and larger along with the screwing, the circumferential fixing screw will slowly disassemble the belt pulley, the disassembling mode only applies force to the motor input shaft, other parts of the motor 1 are not affected, and in addition, the number of detachable fixing screws can be increased or decreased according to different structures of the belt wheel 2, so that the universality of the dismounting tool is ensured.

When the belt wheel 2 needs to be assembled, the automatic rotating support 3-7 can be rotated to an assembly tool, the position is adjusted by using the automatic telescopic supporting rod 3-8, the assembly fixing screw 3-6 penetrates through the center of the assembly disc and is screwed with the central threaded hole of the motor input shaft 1-1 to achieve the fixing purpose, then the assembly screwing screw 3-4 is slowly screwed, the acting force of the assembly screwing screw 3-3 against the belt wheel is larger and larger along with the screwing, and the belt wheel is assembled on the motor input shaft 1-1 along with the acting force of the assembly screwing screw 3-3.

The automatic rotating supports 3-7 can automatically rotate to the required tool positions at any time according to the dismounting requirements, and the automatic rotating support saves time and labor and has high automation degree.

The automatic telescopic supporting rods 3-8 can automatically adjust the height according to the heights of different motors.

The above description is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, several modifications and variations can be made without departing from the technical principle of the present invention, and these modifications and variations should also be regarded as the protection scope of the present invention.
