Referring to fig. 1 to 3, for convenience of illustration, only the parts related to the present embodiment are shown, and the details are as follows:

a motor rotor installation guiding device is used for a device which plays a role in guiding when a motor rotor 1 and a motor stator 2 are installed. The device specifically comprises a positioning base 3, a guide structure and a guide rod 4.

Wherein the positioning base 3 is fixedly connected with a motor stator end cover 6 through a mounting screw 5. The positioning base 3 is provided with a screw hole corresponding to the fixing hole of the motor stator end cover 6 for accommodating the mounting screw 5 to pass through, and the mounting screw 5 passes through the screw hole from bottom to top to be fixed in the fixing hole of the end cover, so that the positioning base 3 and the motor stator end cover 6 are fixed together.

The axis of the positioning base 3 is provided with a through positioning hole 7 corresponding to the shaft hole of the motor stator 2, and the lower surface of the positioning base 3 is provided with a guide sleeve 8 which is coaxial with the positioning hole 7 and has the same inner diameter. The effect of uide bushing 8 and locating hole 7 is that it passes through to hold the electric motor rotor axle, and the height that highly is greater than positioning base 3 of uide bushing 8 makes the spacing effect of uide bushing 8 to the electric motor rotor axle more obvious.

The guide structure comprises a guide sleeve 9 and a guide shaft 10; the guide sleeve 9 is sleeved on the motor rotor shaft, and the guide shaft 10 is fixedly connected to the lower end of the motor rotor shaft through a screw. The motor rotor shaft is wrapped by the guide sleeve 9 and the guide shaft 10, so that the functions of guiding and protecting are achieved, and damage to the shaft in the guiding process is prevented. The outer diameter of the guide shaft 10 is equal to the outer diameter of the guide sleeve 9, so that the outer part of the guide structure is flat and smooth, and the guide shaft can be conveniently and smoothly inserted into the positioning hole 7 of the positioning base 3.

The inner diameter of the positioning hole 7 of the positioning base 3 is matched with the outer diameter of the guide structure (guide shaft 10), so that the guide structure can penetrate through the positioning hole 7 and cannot shake in the positioning hole 7.

One end of the guide rod 4 is meshed in a preset mounting hole of the motor stator end cover 6 in a threaded manner, the other end of the guide rod 4 is suspended, and the other end of the guide rod 4 is inserted into a reserved mounting hole of the motor rotor end cover from bottom to top when the motor rotor 1 moves downwards through the hoisting mechanism. The number of the guide rods 4 is not limited, and the guide rods 4 are used for guiding and limiting the position between the motor rotor 1 and the motor stator 2 in the descending process.

Install structures such as end cover in advance on motor stator 2, later with motor stator 2 install this application positioning base 3 on, will fix a position base 3 to motor stator 2 lower extreme through the screw. And a guide rod 4 is inserted into a mounting hole reserved at the upper end of the motor stator 2. The state at this time is shown in fig. 1.

The motor rotor 1 is hoisted by the hoisting mechanism and the motor rotor 1 is slowly lowered above the motor stator 2, and the guide rod 4 is the highest in height, so that the guide rod 4 is firstly inserted into a mounting hole reserved on the end cover of the motor rotor to realize primary positioning; along with the motor rotor 1 continues to be transferred, the guiding structure on the motor rotor shaft enters the positioning hole 7 and the guiding sleeve 8 of the positioning base 3 to realize final positioning. The state at this time is shown in fig. 2.

Continuing to put motor rotor 1 down to motor rotor 1 and get into motor stator 2 completely, the guide bar 4 of motor stator 2 upper end stretches out from motor rotor 1's mounting hole completely this moment, and motor rotor axle and guide structure stretch out from uide bushing 8 completely, as shown in fig. 3, accomplish the dress together of motor rotor 1 and stator.
