Example 1

Referring to the attached drawings 1-6, the motor heat dissipation fan blade dismounting device comprises a screw rod 1, a nut 2, a guide rod 3, a sliding sleeve 4, a dismounting claw 5 and a handle 6; the screw nut 2 is matched with the screw rod 1; the screw nut 2 is sleeved on the screw rod 1; the two guide rods 3 are welded and fixed on two sides of the nut 2 in a straight line shape; the sliding sleeve 4 is matched with the guide rod 3; the sliding sleeve 4 is sleeved on the guide rod 3 and can slide along the guide rod 3; the disassembling claw 5 is welded and fixed on the sliding sleeve 4; the disassembling claw 5 is provided with a claw hook 501; the claw hooks 501 of the two dismounting claws 5 are oppositely arranged; the lower end of the screw rod 1 is conical; the upper end of the 1 is provided with a handle through hole 101; the handle 6 is matched with the handle through hole 101; the handle 6 is inserted into the handle through hole 101 and can slide along the axial direction of the handle through hole 101.

The using method comprises the following steps: when the motor heat dissipation fan blade 7 needs to be disassembled, the two sliding sleeves 4 slide outwards along the guide rod 3, so that the distance between the two disassembling claws 5 is increased, and the disassembling claws 5 can be clamped to disassembling holes of the heat dissipation fan blade 7 conveniently; then the conical tip part at the lower end of the screw rod 1 is tightly propped against the central hole at the shaft end of the motor shaft 8; then, the screw rod 1 is rotated through the handle 6, the screw nut 2 slides along the screw rod 1, so that the claw hooks 501 of the disassembling claws 5 are aligned with the disassembling holes of the heat dissipation fan blades 7, then the two sliding sleeves 4 slide inwards along the guide rods 3, the two claw hooks 501 are clamped into the disassembling holes of the corresponding heat dissipation fan blades 7, then the screw rod 1 is rotated through the handle 6, the screw nut 2 slides along the screw rod 1 in the direction far away from the motor shaft 8, so that the heat dissipation fan blades 7 are slowly separated from the motor shaft 8, and the disassembling of the heat dissipation fan blades 7 is completed.

When dismantling the epaxial heat dissipation fan blade 7 of horizontal direction motor, because handle 6 can slide along the axis direction of handle via hole 101, consequently can make handle 6 rotate in the space of horizontal direction motor shaft top always, avoided because of horizontal direction motor shaft and ground space not enough, lead to handle 6's operation inconvenient. For the distance between the dismounting holes of different heat dissipation fan blades 7, only the relative distance between the claws 501 needs to be properly adjusted, and the distance between the dismounting holes of various heat dissipation fan blades 7 can be suitable.

Can find out through the above description, the utility model discloses can be convenient dismantle the motor heat dissipation fan blade to simple structure, convenient operation, applicable in the dismantlement of the heat dissipation fan blade 7 of various power motors, application scope is wide.

Two ends of the handle 6 are provided with convex stoppers 601; the stop block 601 is spherical; the diameter of the sphere is larger than the diameter of the handle via hole 101.

Therefore, the handle 6 can be prevented from slipping through the handle through hole 101 to cause the loss of the handle 6, and the handle 6 cannot be found in the next use; and the spherical stopper 601 can improve the comfort of the hand of the operator.

At least one of the stoppers 601 is screw-coupled to the handle 6.

Therefore, the stop block 601 is screwed off from the handle 6, so that the handle 6 can be taken off from the screw rod 1, and the handle 6 can be conveniently replaced.

A locking threaded hole 401 is formed in the sliding sleeve 4; a locking screw 402 is screwed in the locking threaded hole 401.

The sliding sleeve 4 can be locked to the guide rod 3 by the locking screw 402; in the dismounting process, the sliding sleeve 4 can be prevented from moving outwards, so that the claw hook 501 is separated from the dismounting hole of the heat dissipation fan blade 7, and the dismounting failure is avoided.

The guide rod 3 is provided with scale marks 301 in the length direction.

Thus, an operator can judge whether the claw hook 501 is clamped into the dismounting hole of the heat dissipation fan blade 7 in place according to the scale marks 301, because for the same type of motor, after the claw hook 501 is clamped into the dismounting hole of the heat dissipation fan blade 7 in place, the positions of the scale marks 301 corresponding to the sliding sleeve 4 are the same.

The scale mark 301 is oppositely arranged on the side surface of the guide rod 3.

Therefore, no matter how the utility model is placed, the operator can be ensured to conveniently see the scale marks 301.

The guide rod 3 is a hollow tube.

Thus, the weight of the utility model can be reduced.

The free end of the guide rod 3 is connected with a plug 302 in a threaded manner.

This prevents the sliding sleeve 4 from sliding off the free end of the guide rod 3.

The above description is only for the preferred embodiment of the present invention, and is not intended to limit the present invention, and any slight modifications, equivalent replacements and improvements made by the technical spirit of the present invention to the above embodiments should be included in the technical solution of the present invention.
