Example 1
Referring to fig. 1-2, the embodiment provides a disassembly tool for a circular nut of a generator stator through-screw, which comprises a body 1 and a cylindrical pin 2, wherein a first through hole 3 is formed in the middle of the body 1, a plurality of second through holes 4 are formed in the side face of the body, the first through hole 3 is used for sleeving the circular nut, and the second through holes 4 are used for inserting the cylindrical pin 2.
In the specific implementation process, the body 1 is sleeved on the round nut to be disassembled, then the second through holes 4 on the side face of the body 1 are aligned with the side face holes of the round nut by adjusting the rotary body 1, a test staff inserts cylindrical pins into the second through holes 4 and sleeves the cylindrical pins, and then the round nut can be disassembled by matching with a socket wrench. The body occupation space is little, and the staff of being convenient for dismantle the round nut in the region that the space is narrow.
Referring to fig. 1, a body 1 of the present embodiment is a hexagonal prism with an opening in the middle.
In the specific implementation process, the sleeve is conveniently sleeved on the outer side of the hexagonal prism-shaped body 1, and the disassembly is convenient.
Referring to fig. 2, the second through holes 4 of the present embodiment are respectively opened at 6 sides of the hexagonal prism.
In the specific implementation process, the second through holes 4 formed in the 6 sides of the hexagonal prism ensure that the cylindrical pins 2 are inserted from a plurality of angles, so that the body 1 and the round nut are clamped, and relative rotation between the body 1 and the round nut is prevented.
The axial length of the second through hole 4 in this embodiment is consistent with that of the round nut side hole.
In the concrete implementation process, the axial length of the second through hole 4 is consistent with that of the round nut side hole, so that the second through hole 4 can be aligned with the round nut side hole when the cylindrical pin 2 is detached, and the body 1 and the round nut can be clamped mutually by the insertion of the cylindrical pin 2.
