Description

Technical Field

[0001] This utility model relates to a pressure shaping fixture for irregularly shaped rotors. Background Technology

[0002] In modern industrial production, rotors, as key components of various rotating machinery, play a crucial role in the operational stability and efficiency of the entire equipment. With the continuous development of industrial technology, the requirements for rotor shape design are becoming increasingly diverse and complex, leading to the widespread application of irregularly shaped rotors. However, the special shape of irregularly shaped rotors presents numerous challenges to the shaping process during manufacturing.

[0003] Traditional rotor shaping fixtures are typically designed for rotors of conventional shapes, and their structures are relatively fixed. When dealing with irregularly shaped rotors, these traditional fixtures have significant limitations. Due to the irregular shape of the rotor, it is difficult to achieve an ideally uniform contact and stress distribution with the traditional fixture. Therefore, using traditional shaping fixtures to shape irregularly shaped rotors often results in uneven rotor shapes. Utility Model Content

[0038] To enable those skilled in the art to understand the technical solution of this utility model more clearly, the present utility model will be further described in detail below with reference to the embodiments and accompanying drawings, but the implementation of this utility model is not limited thereto.

[0039] like Figures 1-13 As shown, the pressure forming fixture for the irregular rotor provided in this embodiment includes a support module 1, a positioning module 2 above the support module 1, and a pressure module 3 above the positioning module 2. The positioning module 2 includes a spindle fixing plate 201, and a spindle 202 is fixed at the center of the spindle fixing plate 201 by bolts. Multiple first magnetic groove positioning keyways 2011 are evenly arranged on the outer side of the spindle 202 and along the circumference of the spindle 202 on the spindle fixing plate 201. A first shape positioning keyway 2012 is arranged at intervals on the radial outer side of each first magnetic groove positioning keyway 2011. A magnetic groove positioning key 203 and a shape positioning key 204 with their tops extending outward from the outer side of the spindle fixing plate 201 are provided in the first magnetic groove positioning keyway 2011 and the first shape positioning keyway 2012. The magnetic groove positioning key 203 and the shape positioning key 204 can be gently tapped into the first magnetic groove positioning keyway 2011 and the first shape positioning keyway 2012.

[0040] By combining the first magnetic groove positioning keyway 2011 and the first outer shape positioning keyway 2012, dual precise positioning of the magnetic steel groove and the complex shape of the irregular rotor 7 is achieved. This design not only solves the problem of inaccurate positioning caused by the irregular shape of the irregular rotor 7 in traditional tooling, but also ensures synchronous alignment of the magnetic steel groove and the outer shape, avoiding displacement or rotation errors during the forming process.

[0041] In this embodiment, as Figure 10 As shown, the positioning module 2 also includes a lower pressure plate 205. The lower pressure plate 205 is provided with a second magnetic groove positioning keyway 2051 and a second shape positioning keyway 2052 through which the magnetic groove positioning key 203 and the shape positioning key 204 pass. The center of the lower pressure plate 205 is provided with a first mandrel through hole 2053 through which the mandrel 202 passes, allowing the magnetic groove positioning key 203, the shape positioning key 204 and the mandrel 202 to pass through, ensuring that the positioning of the lower pressure plate 205 is consistent with that of the mandrel fixing plate 201. During pressure shaping, the irregular rotor 7 is placed on the lower pressure plate 205 and cooperates with the pressure module 3 to evenly transmit pressure to the irregular rotor 7.

[0042] In this embodiment, as Figure 5As shown, the support module 1 includes a base 101, and a lower mold base 102 is provided above the base 101. The mandrel fixing plate 201 is fixed on the lower mold base 102 to provide stable support for the tooling. The pressurizing module 3 includes an upper pressure plate 301 and an upper mold base 302. The upper pressure plate 301 and the upper mold base 302 are fixedly connected by bolts to provide shaping pressure for the tooling. A pressure power source, such as a hydraulic cylinder, is connected above the upper mold base 302. The specific method can be selected by those skilled in the art as needed.

[0043] In this embodiment, as Figure 11 As shown, the upper pressure plate 301 is provided with a third magnetic groove positioning keyway 3011 and a third shape positioning keyway 3012 into which the top ends of the magnetic groove positioning key 203 and the shape positioning key 204 are inserted. When pressure is applied, the upper pressure plate 301 can pass through the magnetic groove positioning key 203 and the shape positioning key 204 and press completely onto the irregular rotor 7, and can ensure the vertical movement of the upper pressure plate 301 to ensure uniform pressure application.

[0044] In this embodiment, as Figure 1 As shown, a first ball bearing guide post 4 is provided between the upper mold base 302 and the lower mold base 102. There are four first ball bearing guide posts 4, which are respectively located at the four corners between the upper mold base 302 and the lower mold base 102. Through holes are provided at the four corners of the upper mold base 302, and guide sleeves are provided in the through holes. The first ball bearing guide posts 4 are inserted into the guide sleeves, and the bottom of the first ball bearing guide posts 4 are inserted into the lower mold base 102. During the pressurization process, the upper mold base 302 is guided to descend vertically to avoid tilting or displacement.

[0045] In this embodiment, as Figure 4 As shown, it also includes an unloading module 5, which includes a ejector plate 501. The ejector plate 501 is disposed between the spindle fixing plate 201 and the lower pressure plate 205. A lifting plate 502 is disposed at intervals below the ejector plate 501. A lifting column 503 is disposed on the top surface of the lifting plate 502. The lifting column 503 passes through the spindle fixing plate 201 and is connected to the bottom surface of the ejector plate 501. The ejector plate 501 is lifted by the lifting column 503, which drives the rotor to disengage from the tooling, making it easy to remove the rotor. Power can be provided to the lifting plate 502 using equipment such as cylinders. The specific method can be selected by those skilled in the art.

[0046] In this embodiment, as Figure 13 As shown, the ejector plate 501 is provided with a fourth magnetic groove positioning keyway 5011 and a fourth external shape positioning keyway 5012 through which the magnetic groove positioning key 203 and the external shape positioning key 204 pass. The ejector plate 501 is provided with a second mandrel through hole 5013 through which the mandrel 202 passes. During the ejection process, the magnetic groove positioning key 203 and the external shape positioning key 204 can still maintain their engagement with the rotor to ensure the smoothness of the ejection. The ejector plate 501 and the lower pressure plate 205 are fixedly connected by bolts.

[0047] In this embodiment, as Figure 1 As shown, the four corners of the spindle fixing plate 201 are provided with second ball guide posts 6. The four corners of the ejector plate 501 are fitted onto the second ball guide posts 6. The four corners of the ejector plate 501 are provided with through holes, and guide sleeves are provided in the through holes. The second ball guide posts 6 are inserted into the guide sleeves, and the bottom of the second ball guide posts 6 is inserted into the spindle fixing plate 201 to ensure the smooth lifting and lowering of the ejector plate 501 and to ensure that the rotor is not scratched during ejection.

[0048] In this embodiment, as Figure 8 As shown, there are twenty first magnetic groove positioning keyways 2011. The twenty first magnetic groove positioning keyways 2011 are evenly distributed on the spindle fixing plate 201 and along the circumference of the spindle 202, providing dense positioning points to ensure that the magnetic grooves and shape of the rotor can be accurately positioned.

[0049] During tooling assembly, the magnetic groove positioning key 203 and the shape positioning key 204 are inserted from the bottom surface of the mandrel fixing plate 201, pass through the mandrel fixing plate 201, the ejector plate 501 and the lower pressure plate 205 in sequence, and extend outward by a certain length.

[0050] The specific processing flow is as follows:

[0051] Align the magnetic slot of the irregular rotor 7 with the magnetic slot positioning key 203, insert the irregular rotor 7 and move it down onto the lower pressure plate 205. At this time, the outer wall of the irregular rotor 7 contacts the outer shape positioning key 204. The shape of the outer shape positioning key 204 matches the shape of the outer wall of the irregular rotor 7, thus completing the positioning of the irregular rotor 7. Then, the upper pressure plate 301 presses down. During the pressing process, it will pass through the magnetic slot positioning key 203 and the outer shape positioning key 204, and finally press on the irregular rotor 7 to press and shape the irregular rotor 7. After the shaping is completed, the upper pressure plate 301 moves up, and the lifting plate 502 moves up, driving the ejector plate 501 to move up, thereby causing the lower pressure plate 205 and the irregular rotor 7 above the ejector plate 501 to move up, so that the irregular rotor 7 can be smoothly removed from the tooling.

[0052] In summary, this embodiment achieves precise positioning of both the magnetic slots and the complex shape of the irregularly shaped rotor 7 by combining multiple magnetic slot positioning keyways and external shape positioning keyways. This design not only solves the problem of inaccurate positioning caused by the irregular shape of the rotor 7 in traditional tooling, but also ensures synchronous alignment of the magnetic slots and the external shape, avoiding displacement or rotation errors during the forming process.

[0053] The above description is only a further embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the scope disclosed by the present utility model, based on the technical solution and concept of the present utility model, shall fall within the protection scope of the present utility model.
