DETAILED DESCRIPTION OF THE EMBODIMENTS

[0026] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0027] Please refer to Figures 1 - 4 , a quick disassembly and assembly tooling for an electric submersible pump rotor bearing, including a side plate 1 and a top plate 2. The side plates 1 are symmetrically arranged on the left and right sides below the top plate 2. The two side plates 1 with legs 21 provide stable support for the top plate 2, so that the top plate 2 is stably located above the equipment. It further includes:

[0028] A centering assembly, the centering assembly includes a cover body 3, a worm gear 4, a worm 5, a first handle 6, a double-threaded rod 7 and a cross beam 8. A cover body 3 is arranged on one side of the side plate 1. A worm 5 and two worm gears 4 are arranged in the cover body 3. The worm 5 meshes with the two worm gears 4. Both ends of the worm 5 penetrate through the cover body 3 and are connected to the first handle 6. A double-threaded rod 7 is also rotatably arranged on the front and rear sides of the two side plates 1. One end of the double-threaded rod 7 penetrates through the side plate 1 and the center of the worm gear 4. The cross beam 8 is arranged in two groups symmetrically left and right. The front and rear sides of the cross beam 8 are threadedly connected to the double-threaded rod 7;

[0029] When it is necessary to disassemble and assemble the bearings of submersible motor rotors of different specifications, turn the first handle 6. The first handle 6 drives the worm 5 to rotate. Since the worm 5 meshes with two sets of worm wheels 4, the rotation of the worm 5 will drive the two sets of worm wheels 4 to rotate synchronously. The center of the worm wheel 4 is connected to the left - hand and right - hand threaded rod 7. The rotation of the worm wheel 4 causes the left - hand and right - hand threaded rod 7 to rotate on the side plate 1. Because the front and rear sides of the cross beam 8 are threadedly connected to the left - hand and right - hand threaded rod 7, as the left - hand and right - hand threaded rod 7 rotates, the two symmetrically arranged cross beams 8 will move closer to or away from each other. In this way, the distance between the cross beams 8 can be flexibly adjusted according to the width of the submersible motor rotor, realizing the centering and positioning of submersible motor rotors of different specifications, and ensuring that the tooling can adapt to various operation requirements.

[0030] A clamping assembly, the clamping assembly is arranged at one end of the cross beam 8 close to the left - hand and right - hand threaded rod 7 so as to stably embrace the submersible pump housing;

[0031] A pressing - down assembly, the pressing - down assembly includes a screw rod 9, a second handle 10, a mounting disc 11 and a pressing plate 12. The lower part of the screw rod 9 penetrates through the top plate 2 and is connected to the mounting disc 11. The pressing plate 12 is arranged below the mounting disc 11. The second handle 10 is arranged above the screw rod 9. The screw rod 9 is threadedly connected to the top plate 2. After the centering and positioning of the submersible motor rotor and the fixation of the housing are completed, the disassembly and assembly operation of the bearing is carried out. Rotate the second handle 10. Since the screw rod 9 is threadedly connected to the top plate 2, the rotation of the second handle 10 will cause the screw rod 9 to move downward on the top plate 2. The mounting disc 11 is connected to the lower part of the screw rod 9, so the mounting disc 11 moves downward accordingly, and the pressing plate 12 below the mounting disc 11 also descends, assembling the rotor bearing into the submersible pump.

[0032] In this embodiment, when fixing the submersible motor rotor, select a suitable clamping plate 15 according to the specification of the submersible pump housing. When installing the clamping plate 15, align the insertion block 13 with the slot at one end of the cross beam 8 close to the left - hand and right - hand threaded rod 7 and insert it. The elastic members (composed of a spring 16 and a telescopic rod 17) in the upper and lower movable slots of the insertion block 13 will be compressed during the insertion process. When the insertion block 13 is inserted in place, the locking block 14 pops out under the elastic force of the spring 16 and snaps into the corresponding locking hole on the cross beam 8, thus realizing the quick installation of the clamping plate 15. At this time, the clamping plate 15 can fix the submersible pump housing. When it is necessary to replace the clamping plate 15 to adapt to submersible pump housings of different specifications, press the locking block 14 to make it retract into the movable slot against the elastic force of the spring 16, disengaging from the locking hole of the cross beam 8, and then the insertion block 13 can be pulled out of the slot to remove the clamping plate 15, conveniently and quickly replacing the suitable clamping plate 15, enhancing the adaptability of the tooling to different submersible pumps.

[0033] The reinforcing ribs 18 provided on the circumferential side of the mounting disc 11 cooperate with the grooves above the pressing plate 12, increasing the contact area and connection strength between the two, and ensuring the stability of the overall structure. At the same time, the first magnetic attraction block 19 embedded below the mounting disc 11 and the second magnetic attraction block 20 provided above the pressing plate 12 attract each other, further ensuring the tight connection between the mounting disc 11 and the pressing plate 12 and preventing the pressing plate 12 from shaking or falling off during the descent. After the pressing plate 12 descends, pressure is applied to the submersible pump rotor bearing to achieve the installation or disassembly operation of the bearing, ensuring the smoothness and reliability of the downward pressing operation.
