The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0034] In related technologies, the demand for high-speed rotor machinery in air compressors is increasing. The assembly process of rotor shafts is complex. During the assembly process, rotor shafts generally need to be bonded before processing. Due to subsequent processing allowances and process requirements, the coaxiality of the bonded rotor shafts is required to be high. Therefore, how to optimize the processing of rotor shafts and improve the coaxiality of rotors has become an urgent problem to be solved in this field.

[0035] The following is for reference. Figures 1-5 This invention describes a tooling assembly for a rotor assembly according to an embodiment of the present invention.

[0036] According to the present invention, the tooling assembly 1 for the rotor assembly 2 includes: a base 11, on which a first groove 131 is provided, at least a portion of one side of the rotor assembly 2 is received in the first groove 131 and abuts against the outer edge of the first groove 131, the extending direction of the first groove 131 being the same as the axial direction of the rotor assembly 2; and a cover plate 12, on which a second groove 132 is provided, the extending direction of the first groove 131 being the same, at least a portion of the other side of the rotor assembly 2 is received in the second groove 132 and abuts against the outer edge of the second groove 132.

[0037] Specifically, a first groove 131 is provided on the base 11. The first groove 131 is used to accommodate one side of the rotor assembly 2, and the inner wall of the first groove 131 abuts against at least part of the rotor assembly 2, so that the rotor assembly 2 is in close contact with the outer edge of the first groove 131. The extension direction of the first groove 131 is consistent with the axial extension direction of the rotor assembly 2. Placing the rotor assembly 2 in the first groove 131 can ensure the coaxiality of the rotor assembly 2 in the extension direction. The tooling assembly 1 also includes a cover plate 12, on which a second groove 132 is provided. The extension direction of the second groove 132 is the same as that of the first groove 131, indicating that the extension direction of the second groove 132 is the same as that of the rotor assembly 2. When the rotor assembly 2 is placed in the first groove 131 and the cover plate 12 is combined with the base 11, the other side of the rotor assembly 2 is received in the second groove 132, so that the other side of the rotor assembly 2 is in close contact with the outer edge of the second groove 132. Through the axial limiting of the rotor assembly 2 by the first groove 131 and the second groove 132, the rotor assembly 2 can be firmly fixed, ensuring that the rotor assembly 2 is accurately and stably positioned in the axial direction, further ensuring the coaxiality of the rotor assembly 2, improving the stability of the rotor assembly 2 during processing or testing, and also helping to improve production efficiency and product quality.

[0038] According to the present invention, the tooling assembly 1 has a first groove 131 on the base 11 and a second groove 132 on the cover plate 12. Both the first groove 131 and the second groove 132 extend along the axial direction of the rotor assembly 2. When the rotor assembly 2 is placed on the tooling assembly 1, the first groove 131 and the second groove 132 simultaneously clamp the rotor assembly 2. The outer periphery of the rotor assembly 2 abuts against the outer periphery of the first groove 131 and the outer periphery of the second groove 132, respectively, to ensure the coaxiality of the rotor assembly 2.

[0039] According to some embodiments of the present invention, the base 11 includes: a base plate 111, on which a first groove 131 is provided; an end plate 112, which is disposed at one end of the base plate 111, and a first fixing part 141 located at one end of the first groove 131 is provided on the end plate 112, the first fixing part 141 being adapted to abut against one end of the rotor assembly 2; and a second fixing part 142, which is movably disposed in the first groove 131 and is disposed opposite to the first fixing part 141, the second fixing part 142 being adapted to abut against the other end of the rotor assembly 2.

[0040] Specifically, the base plate 111 is the main load-bearing part of the base 11. A first groove 131 is provided on the base 11. The first groove 131 provides an axially extending support surface for the bottom of the rotor assembly 2, ensuring the basic positioning of the rotor assembly 2 in the tooling assembly 1.

[0041] The end plate 112 is disposed at one end of the base plate 111 and is used to abut against one end of the rotor assembly 2. A first fixing part 141 is provided on the end plate 112. The fixing part is located at one end of the first groove 131. When the rotor assembly 2 is placed on the base 11, one end of the rotor assembly 2 is in close contact with the first fixing part 141, thereby fixing one end of the rotor assembly 2 and helping to prevent the rotor assembly 2 from shaking on the base 11.

[0042] The second fixing part 142 is correspondingly provided to the first fixing part 141. The second fixing part 142 is located at the other end of the first groove 131 and can move relative to the extending direction of the first groove 131. This allows the second fixing part 142 to be adjusted according to the size and shape of the rotor assembly 2, ensuring that the second fixing part 142 can be in close contact with the other end of the rotor assembly 2. By movably providing the second fixing part 142 in the second groove 132 for close contact with the other end of the rotor assembly 2, the flexibility and applicability of the tooling assembly 1 are increased, enabling the tooling assembly 1 to be used to fix rotor assemblies 2 of different sizes and shapes. Through the synergistic effect of the base plate 111, the end plate 112, and the second fixing part 142, a stable and precise fixing environment is provided for the rotor assembly 2. The corresponding arrangement of the first fixing part 141 and the second fixing part 142 ensures the precise positioning of the rotor assembly 2 in the tooling assembly 1, thereby improving the accuracy and efficiency of the rotor assembly 2 processing or testing process.

[0043] According to some embodiments of the present invention, a first through hole is formed on the first fixing part 141 extending in the direction of the first groove 131, and a second through hole is formed on the second fixing part 142 extending in the direction of the first groove 131. The rotor assembly 2 has a first extension 211 and a second extension 221 extending away from each other in the axial direction, respectively. The first extension 211 is adapted to pass through the first through hole and abut against the inner wall of the first through hole, and the second extension 221 is adapted to pass through the second through hole and abut against the inner wall of the second through hole.

[0044] Specifically, a first through hole is provided on the first fixing part 141, extending in the direction of the extension of the first groove 131 (i.e., the axial direction of the rotor assembly 2). The first through hole is used to mate with one end of the rotor assembly 2. A second through hole is provided on the second fixing part 142, extending in the axial direction. The second through hole is adapted to mate with the other end of the rotor assembly 2. A first extension 211 is formed at one axial end of the rotor assembly 2, extending toward the end plate 112 and adapted to pass through the first through hole to mate with the first fixing part 141. A second extension 221 is formed at the other end of the rotor assembly 2, extending toward the second fixing part 142 and... Suitable for mates with the second through hole, when the rotor assembly 2 is placed in the first groove 131, the first extension 211 passes through the first through hole and comes into close contact with the inner wall of the first through hole, while the second extension 221 passes through the second through hole and comes into close contact with the inner wall of the second through hole, ensuring the precise positioning of the rotor assembly 2. It also provides additional support for the rotor assembly 2 through the contact between the first through hole and the second through hole and the first extension 211 and the second extension 221, improving the stability of the rotor assembly 2 in the first groove 131, improving the accuracy and processing efficiency of the rotor assembly 2 in the processing or testing process, and also helping to avoid damage to the rotor assembly 2 due to shaking.

[0045] According to some embodiments of the present invention, the tooling assembly 1 further includes: a clamping plate 15, which is detachably disposed at the other end of the base plate 111. The clamping plate 15 is adapted to be connected to the base plate 111 and the cover plate 12 and to push the second fixing part 142 toward the second fixing part 142 to clamp the rotor assembly 2 in the axial direction.

[0046] Specifically, the clamping plate 15 can be connected to the base plate 111 and the cover plate 12 by bolts, pins or other fasteners. The clamping plate 15 is located at the other end of the base plate 111 and is positioned opposite to the end plate 112. The clamping plate 15 is adapted to provide additional pressure to the second fixing part 142 to ensure that the rotor assembly 2 is firmly fixed in the tooling assembly 1. When the rotor assembly 2 is placed in the first groove 131, the two axial ends of the rotor assembly 2 respectively engage with the first fixing part 141 and the second fixing part 142 for abutment. The clamping plate 15 can be installed on the base plate 111 and connected to the cover plate 12 and the base plate 111. By pushing the clamping plate 15, the second fixing part 142 can be pushed toward the first fixing part 141 to press the rotor assembly 2 axially, preventing the rotor from moving during processing or testing, and improving the product quality of the tooling assembly 1.

[0047] According to some embodiments of the present invention, a third through hole is formed on the clamping plate 15, which is suitable for the second extension 221 to pass through.

[0048] Specifically, a third through hole is provided on the clamping plate 15. The second extension 221 of the rotor assembly 2 can pass through the third through hole after passing through the second through hole. When the clamping plate 15 is installed on the base plate 111 and tightened, the third through hole will allow the second extension 221 to continue to extend and provide additional support and fixation for the second extension 221, ensuring that the second extension 221 remains stable when passing through the third through hole and does not shake or shift. At the same time, it also helps to disperse the pressure exerted by the clamping plate 15 on the second fixing part 142, thereby protecting the rotor assembly 2 from damage.

[0049] According to some embodiments of the present invention, a plurality of first connecting holes are provided on the cover plate 12 at intervals, and a plurality of second connecting holes corresponding one-to-one with the first connecting holes are formed on the bottom plate 111. The cover plate 12 and the bottom plate 111 are fixed together by bolts to stop the rotor assembly 2 from the outer edge of the first groove 131 and the outer edge of the second groove 132.

[0050] Specifically, the cover plate 12 has multiple spaced-apart first connecting holes, and the base plate 111 has multiple second connecting holes corresponding to the first connecting holes. By fixing with bolts, a robust connection is formed between the cover plate 12 and the base plate 111, tightly clamping them together. This connection method is not only strong and reliable but also easy to disassemble and reinstall, increasing the flexibility and ease of use of the tooling assembly 1. By fixing the cover plate 12 and the base plate 111 together with bolts, the rotor assembly 2 is firmly clamped between the first groove 131 and the second groove 132. The clamping action of the first groove 131 and the second groove 132 ensures that the rotor assembly 2 is in close contact with the outer edges of the first groove 131 and the second groove 132, thereby guaranteeing the coaxiality of the rotor assembly 2.

[0051] The rotor assembly 2 according to this utility model is briefly described below.

[0052] The rotor assembly 2 according to this utility model is assembled using the tooling assembly 1 described in any of the above embodiments and includes a front bearing 21, a rear bearing 22 and a rotor magnet 23. The front bearing 21 is received at one end of the first groove 131, the rear bearing 22 is movably received at the other end of the first groove 131, and the rotor magnet 23 is disposed between the front bearing 21 and the rear bearing 22 and is respectively connected to the front bearing 21 and the rear bearing 22.

[0053] Specifically, when the rotor assembly 2 is assembled into the tooling assembly 1, the front bearing 21 and the rear bearing 22 will be fixed by the first fixing part 141 and the second fixing part 142 of the tooling assembly 1, respectively, ensuring the stability and accuracy of the rotor assembly 2 in the tooling assembly 1 and providing stable support for subsequent processing or testing. At the same time, since the rear bearing 22 and the second fixing part 142 can move within the first groove 131, the rear bearing 22 and the second fixing part 142 can flexibly cooperate, allowing rotor assemblies 2 of different sizes to flexibly cooperate with the tooling assembly 1.

[0054] According to some embodiments of the present invention, the outer periphery of the rotor magnet 23 abuts against the outer edge of the first groove 131 and the outer edge of the second groove 132, respectively.

[0055] Specifically, the outer periphery of the rotor magnet 23 is in close contact with the outer edges of the first groove 131 and the second groove 132, ensuring the precise positioning of the rotor magnet 23 in the tooling assembly 1 and guaranteeing the stability and coaxiality of the rotor magnet 23, the front bearing 21, and the rear bearing 22. When the outer periphery of the rotor magnet 23 is in close contact with the outer edges of the first groove 131 and the second groove 132, the first groove 131 and the second groove 132 provide stable support for the rotor assembly 2. Through the flexible cooperation between the rotor magnet 23 and the tooling assembly 1, the assembly process is simplified.

[0056] According to some embodiments of the present invention, adhesive layers are respectively provided at both ends of the rotor magnet 23 along the axial direction.

[0057] Specifically, by connecting the rotor magnet 23 to the front bearing 21 and the rear bearing 22 using an adhesive layer, the overall structural strength of the rotor assembly 2 can be enhanced, thereby extending the service life of the rotor assembly 2. Using an adhesive layer to fix the rotor magnet 23 simplifies the assembly process and improves the processing efficiency of the rotor assembly 2.
