[0030] 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.

[0031] Refer to Figure 1 , Figure 2 and Figure 4 , an embodiment provided by the present utility model: A variable-diameter sleeve for assisting a rotor tooling fixture includes a plurality of variable-diameter sleeve bodies 1 and a fixed plate 2. Four slots 3 are provided on the outer sides of the plurality of variable-diameter sleeve bodies 1. A plurality of slide grooves 5 are provided on the outer side of the fixed plate 2. Fixed grooves 4 are provided on the inner side walls of the slide grooves 5. A moving plate 6 is slidably connected to the inner wall of the fixed groove 4. A spring 7 is fixedly connected to one side of the moving plate 6. Two clamping posts 8 are fixedly connected to the other side of the moving plate 6. A slide plate 9 is fixedly connected to the outside of the moving plate 6. The slide plate 9 is adapted to the slide groove 5. The outer parts of the plurality of slide plates 9 are respectively slidably connected to the inner walls of the corresponding slide grooves 5. The plurality of variable-diameter sleeve bodies 1 are detachably connected to the outside of the fixed plate 2.

[0032] Specifically, when the reducing sleeve body 1 needs to be installed on the fixing plate 2, manually push the sliding plate 9. The sliding plate 9 slides in the sliding groove 5, and at the same time drives the moving plate 6 connected to it to slide in the fixing groove 4. During the sliding process of the moving plate 6, the spring 7 is compressed, causing the spring 7 to contract into the fixing groove 4. At this time, the clamping post 8 on the moving plate 6 moves inward with the moving plate 6 into the fixing groove 4. Align the reducing sleeve body 1 with the fixing plate 2 so that the clamping groove 3 on the reducing sleeve body 1 is aligned with the fixing groove 4. Release the sliding plate 9. Under the action of the elastic restoring force of the spring 7, the spring 7 pushes the moving plate 6 to move towards the reducing sleeve body 1. The clamping post 8 on the moving plate 6 extends out of the fixing groove 4 and snaps into the clamping groove 3 of the reducing sleeve body 1, thereby fixing the reducing sleeve body 1 on the fixing plate 2. When the reducing sleeve body 1 needs to be disassembled, manually push the sliding plate 9 again. The sliding plate 9 drives the moving plate 6 to slide in the sliding groove 5. The moving plate 6 compresses the spring 7. As the moving plate 6 moves, the clamping post 8 on the moving plate 6 disengages from the clamping groove 3 of the reducing sleeve body 1. At this time, the reducing sleeve body 1 can be removed from the fixing plate 2. Different-sized reducing sleeve bodies 1 can be conveniently replaced to meet the processing requirements of rotors of different specifications, improving the versatility and flexibility of the tooling fixture.

[0033] Refer to Figure 1 , Figure 4 and Figure 5 , the reducing sleeve body 1 includes an outer layer 101, a middle layer 102, an inner layer 103, and a tapered groove 10. The outer layer 101 is arranged on the outside of the reducing sleeve body 1. A middle layer 102 is arranged on the outside of the outer layer 101. An inner layer 103 is arranged on the outside of the middle layer 102. The tapered groove 10 is arranged on the top of the reducing sleeve body 1. The material of the outer layer 101 is alloy steel. The material of the middle layer 102 is copper alloy. The material of the inner layer 103 is cemented carbide.

[0034] Specifically, the outer layer 101 is made of alloy steel, which has high strength and toughness, can withstand certain external force impacts and wear, and at the same time protects the internal structure. The middle layer 102 is made of copper alloy, which has good thermal conductivity and antifriction properties. During the working process, when the rotor and the reducing sleeve body 1 generate friction, heat will be generated. The copper alloy middle layer 102 can play a role in heat dissipation, reducing the impact of the heat generated by friction on the overall performance of the reducing sleeve. At the same time, the antifriction property can reduce the friction coefficient and wear. The inner layer 103 is made of cemented carbide, which has extremely high hardness and wear resistance. After the rotor is installed in the reducing sleeve body 1, the inner layer 103 is in direct contact with the rotor. The cemented carbide material can ensure the accuracy and stability of clamping, is not easy to wear, and guarantees the precision machining requirements for new rotors. The tapered groove 10 can help the rotor quickly locate in the reducing sleeve.

[0035] Refer to Figure 2 and Figure 3, One end of each of the multiple springs 7 is fixedly connected to the inner wall of the corresponding fixing groove 4 respectively, and the outer sides of the multiple springs 7 are respectively slidably connected to the inner wall of the corresponding fixing groove 4.

[0036] Specifically, one end of the spring 7 is fixed to the inner wall of the fixing groove 4, ensuring a stable fixed point for the spring 7 during compression and extension. The spring 7 sliding on the inner wall of the fixing groove 4 enables the spring 7 to move along a fixed direction during compression and extension.

[0037] Working principle: By pushing the sliding plate 9, the sliding plate 9 drives the moving plate 6 to slide in the sliding groove 5. The moving plate 6 compresses the spring 7, causing the clamping post 8 on the moving plate 6 to disengage from the clamping groove 3 of the variable-diameter sleeve body 1. At this time, the variable-diameter sleeve body 1 can be removed from the fixing plate 2. When it is necessary to install the variable-diameter sleeve body 1 on the fixing plate 2, manually push the sliding plate 9. The sliding plate 9 drives the moving plate 6 to slide in the sliding groove 5. The moving plate 6 compresses the spring 7 to make it contract into the fixing groove 4. At this time, align the variable-diameter sleeve body 1 with the fixing plate 2 so that the clamping groove 3 of the variable-diameter sleeve body 1 is aligned with the fixing groove 4. Release the sliding plate 9. Under the elastic restoring force of the spring 7, the spring 7 pushes the moving plate 6 to move towards the variable-diameter sleeve body 1. The clamping post 8 on the moving plate 6 extends out of the fixing groove 4 and is clamped into the clamping groove 3 of the variable-diameter sleeve body 1, thereby fixing the variable-diameter sleeve body 1 on the fixing plate 2. Different-sized variable-diameter sleeve bodies 1 can be conveniently replaced to meet the processing requirements of rotors of different specifications, improving the versatility and flexibility of the tooling fixture. The variable-diameter sleeve body 1 is composed of an outer layer 101, a middle layer 102, and an inner layer 103. The outer layer 101 is made of alloy steel, having high strength and toughness, capable of withstanding certain external force impacts and abrasions, and protecting the internal structure at the same time. The middle layer 102 is made of copper alloy, having good thermal conductivity and antifriction properties. The inner layer 103 is made of cemented carbide, having extremely high hardness and wear resistance. When installing the rotor, the slope-shaped groove 10 can play a role in guiding the rotor into the variable-diameter sleeve.

[0038] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features.
