Description

Technical Field

[0001] The present invention relates to the technical field of motors, and in particular to a motor rotor assembly tool and an assembly method. Background Art

[0002] With the development of social production, traditional motors can no longer meet the needs of higher magnetic density, greater torque and smaller size. In order to break through the magnetic density limit of traditional motors, superconducting motors can be used. Superconducting motors are a new type of synchronous motor that uses superconducting coils to replace conventional copper coils. In the current more mature superconducting motor solutions, superconducting coils (i.e. superconducting magnets) are set in the rotor to generate high-intensity magnetic fields.

[0003] In a superconducting motor using conduction cooling, the superconducting magnet on the rotor is fixed to the support frame, and the superconducting magnet and the support frame are placed in a low-temperature environment (such as the liquid helium temperature zone) at the same time to achieve superconductivity. In order to reduce the transfer of heat between the superconducting motor rotor shaft system and the support frame, a composite material tie rod support assembly with a poor heat transfer coefficient is used as the torque transfer path. The superconducting magnet, support frame and other low-temperature components are fixed to the normal temperature rotor shaft system by connecting the support assembly. During the cooling process, the contraction displacement and deformation of the structure will cause great internal stress; when the superconducting motor is working, the electromagnetic load on the rotor will form a strong electromagnetic torque, which will be output to the superconducting motor shaft system through the support frame and the support assembly.

[0004] During the rotation of the superconducting motor, in order to ensure the uniformity of the magnetic field generated by the superconducting magnet and reduce the rotational inertia of the motor rotor shaft system, these put forward high requirements on the installation and positioning accuracy of the superconducting rotor magnet support frame and support components. The superconducting rotor and the support frame are connected by connecting rods at the ends, but the locking assembly needs to be installed by means of hinges after the relative position relationship between the two is determined. Previously, the superconducting motor rotor shaft system and the support frame were mostly installed by hoisting methods such as the motor rotor hoisting device disclosed in publication number CN117361291A. In this way, it is difficult to avoid the shaking of parts caused by the inertia and contact installation during the assembly process during the crane lifting process, resulting in greater difficulty in assembling the motor rotor shaft system and the support frame, and low assembly accuracy. Therefore, it is necessary to design reasonable tooling for positioning and installing the superconducting rotor and the support frame. Summary of the invention

DETAILED DESCRIPTION

[0019] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0020] In order to solve the technical problems in the prior art that the superconducting motor rotor shaft system 10a and the support frame 20a are difficult to assemble and the assembly accuracy is low, the embodiment of the present invention provides a motor rotor assembly tool and a motor rotor assembly method to assist in the assembly of the rotor shaft system 10a and the support frame 20a, thereby reducing the difficulty of assembling the rotor shaft system 10a and the support frame 20a and improving the assembly accuracy of the rotor shaft system 10a and the support frame 20a.

[0021] It should be noted that the motor rotor assembly tool described in the present invention is used for but not limited to the assembly of the rotor shaft system 10a and the support frame 20a of the superconducting motor. For the convenience of explanation, in the present invention, only the application of the motor rotor assembly tool device to the assembly of the rotor shaft system 10a and the support frame 20a of the superconducting motor is taken as an example for explanation, and the principles of the application of the motor rotor assembly tool to other types of equipment are essentially the same as the principles applied to the assembly of the rotor shaft system 10a and the support frame 20a of the superconducting motor, which will not be described one by one here.

[0022] like Figure 1-3 As shown, the motor rotor assembly tooling provided by the embodiment of the present invention includes a support seat 10, an inner positioning ring 20, an outer positioning ring 30, an axial positioning module 40, an axial adjustment module 50 and a radial adjustment module 60. The inner positioning ring 20 is fixed to the support seat 10 to position and place the rotor shaft system 10a; the outer positioning ring 30 is coaxially arranged on the outer side of the inner positioning ring 20 and fixed to the support seat 10 to preliminarily position the support skeleton 20a; the axial adjustment module 50 is used to adjust the axial position of the support skeleton 20a by configuring the connection between the support seat 10 and the support skeleton 20a; the axial positioning module 40 is used to configure the connection between the rotor shaft system 10a and the support skeleton 20a, adjust and lock the axial position of the rotor shaft system 10a and the support skeleton 20a; the radial adjustment module 60 is used to be inserted between the rotor shaft system 10a and the support skeleton 20a to adjust the coaxiality of the rotor shaft system 10a and the support skeleton 20a.

[0023] Specifically, the motor rotor assembly tooling is provided with a support seat 10, an inner positioning ring 20, an outer positioning ring 30, an axial positioning module 40, an axial adjustment module 50 and a radial adjustment module 60. The inner positioning ring 20 and the outer positioning ring 30 are provided on the support seat 10, which can respectively provide positioning for the rotor shaft system 10a and the support frame 20a, and preliminarily ensure the coaxiality of the rotor shaft system and the support frame. Then, the coaxiality and axial position of the rotor shaft system 10a and the support frame 20a are adjusted through the axial positioning module 40, the axial adjustment module 50 and the radial adjustment module 60 to ensure the assembly accuracy of the rotor shaft system 10a and the support frame 20a. The assembly process is to first assemble the rotor shaft system 10a on the inner positioning ring 20, and then assemble the support frame 20a on the outer positioning ring 30, and then through The axial adjustment module 50 is connected to the support seat 10 and the support frame 20a to adjust the axial position of the support frame 20a; then the axial positioning module 40 is fixedly connected to the rotor shaft system 10a and the support frame 20a to position and fix the axial position of the support frame 20a; after completing the positioning and fixing of the axial position of the support frame 20a, the radial adjustment module 60 is inserted between the rotor shaft system 10a and the support frame 20a to fine-tune the coaxiality of the rotor shaft system 10a and the support frame 20a, and finally the coaxiality and axial relative position of the rotor shaft system 10a and the support frame 20a are guaranteed. Through the above assembly, the assembly difficulty of the rotor shaft system 10a and the support frame 20a can be significantly reduced, and the assembly accuracy of the rotor shaft system 10a and the support frame 20a can be improved.

[0024] In this embodiment, Figure 1-2As shown, the support base 10 includes an upper chassis 11, a lower chassis 12 and a plurality of support columns 13 arranged between the upper chassis 11 and the lower base plate. The lower chassis 12 is supported on the ground, and the inner positioning ring 20 and the outer positioning ring 30 are formed on the upper chassis 11.

[0025] In this embodiment, Figure 2 As shown, an annular positioning stop 21 is provided at the end of the inner positioning ring 20, and the annular positioning stop 21 can be used for the assembly of the rotor shaft system 10a. Specifically, when assembling the rotor shaft system 10a, the rotor of the rotor shaft system 10a is assembled to the annular positioning stop 21 by hoisting the rotor shaft system 10a. The rotor shaft system 10a is assembled to the annular positioning stop 21, and the rotor shaft system 10a is provided with support for the rotor shaft system 10a while positioning the rotor shaft system 10a. The annular positioning stop 21 positions and supports the rotor shaft system 10a, and the rotor shaft system 10a is pre-fixed. The support frame 20a is assembled based on the pre-fixed rotor shaft system 10a, so that the rotor shaft system 10a and the support frame 20a are assembled from the inside to the outside, reducing the difficulty of assembling the rotor shaft system 10a and the support frame 20a.

[0026] In this embodiment, when the support frame 20a is assembled, the support frame 20a is mounted on the outer positioning ring 30 by hoisting, and is spaced from the rotor shaft system 10a. To support the support frame 20a, when the support frame 20a is assembled to a certain position, the axial adjustment module 50 is connected to the support seat 10 and the support frame 20a, so that the axial position of the support frame 20a is preliminarily adjusted by the axial adjustment module 50, so that when the rotor shaft system 10a and the support frame 20a are connected by the axial positioning module 40, the support frame 20a is almost motionless in the axial direction, and the axial positioning module 40 can further fine-tune the position of the support frame 20a by connecting the support frame 20a and the rotor shaft system 10a, and realize the positioning and locking of the axial position of the support frame 20a, and only the coaxiality of the rotor shaft system 10a and the support frame 20a need to be adjusted later.

[0027] In one embodiment, if Figure 1 and 3As shown, the support skeleton 20a is provided with a plurality of installation ports 21a at intervals along the circumferential direction, and the axial positioning module 40 includes a plurality of assembly parts 41 and a first threaded adjustment part 42. Each assembly part 41 is used to be embedded in each installation port 21a, and the first threaded adjustment part 42 is threadedly connected to the assembly part 41 and the rotor shaft system 10a. Specifically, when the rotor shaft system 10a and the support skeleton 20a are connected, each assembly part 41 is respectively embedded in each installation port 21a, and then the first threaded adjustment part 42 is threadedly connected to the assembly part 41 and the rotor shaft system 10a. During the process of the first threaded adjustment part 42 being threadedly connected to the rotor shaft system 10a, the support skeleton 20a is driven to be axially offset through the assembly part 41, and the axial position of the support skeleton 20a is gradually fine-tuned to form the final positioning of the axial position of the rotor shaft system 10a and the support skeleton 20a. When the first threaded adjustment part 42 is threadedly connected to the rotor shaft system 10a, the support skeleton 20a is driven to be axially offset through the assembly part 41, and the axial position of the support skeleton 20a is gradually fine-tuned to form the final positioning of the axial position of the rotor shaft system 10a and the support skeleton 20a. When a threaded adjustment member 42 is tightened, the assembly member 41 is tightly structured with the rotor shaft system 10a, so that the rotor shaft system 10a and the support frame 20a are integrated, preventing the rotor shaft system 10a from rotating and shifting relative to the support frame 20a during the subsequent assembly process, thereby avoiding further adjustment of the support frame 20a. Subsequently, only the coaxiality of the rotor shaft system 10a and the support frame 20a needs to be fine-tuned, thereby ensuring the assembly accuracy of the rotor shaft system 10a and the support frame 20a and reducing the assembly difficulty of the rotor shaft system 10a and the support frame 20a.

[0028] In this embodiment, the number of the supply openings 21 a is four, and the four supply openings 21 a are evenly spaced along the circumferential direction of the support frame 20 a.

[0029] In this embodiment, the shape and size of the assembly part 41 can be adaptively set according to the shape and size of the loading opening 21a. It is only necessary for the assembly part 41 to fit into the loading opening 21a without being offset relative to the supporting frame 20a.

[0030] In this embodiment, the assembly member 41 is engaged with the side wall of the loading port 21 a by friction between the side surface.

[0031] In this embodiment, since the binding force between the assembly part 41 and the supporting frame 20a is relatively large, in order to facilitate the disassembly of the assembly part 41, the assembly part 41 is provided with a first lifting hole 411. Specifically, the lifting hole is a screw hole used to lift or remove parts. In order to facilitate the disassembly of the assembly part 41, the screw is screwed into the first lifting hole 411 to lift the assembly part 41, thereby removing the assembly part 41.

[0032] In one embodiment, in order to improve the tightness between the assembly part 41 and the rotor shaft system 10a, a positioning stop (marked in the figure) is provided on one side where the assembly part 41 and the rotor shaft system 10a are installed in cooperation, and the positioning stop is used to form an interlocking with the rotor shaft system 10a. Specifically, in the process of tightening the first threaded adjustment member 42, the assembly part 41 gradually forms an interlocking with the rotor shaft system 10a through the positioning stop, improving the tightness between the assembly part 41 and the rotor shaft system 10a, so that the rotor shaft system 10a can form an integral whole with the support frame 20a as much as possible, and can move synchronously with the support frame 20a, thereby avoiding the subsequent rotation and axial displacement of the rotor shaft system 10a relative to the support frame 20a.

[0033] In one embodiment, if Figure 1 As shown, the axial adjustment module 50 includes a plurality of second threaded adjustment members 51, each of which is threadedly connected to the support base 10 and the support frame 20a to support and axially adjust the support frame 20a. Specifically, when the support frame 20a is assembled to a certain position of the outer positioning ring 30, each of the second threaded adjustment members 51 is connected to the support base 10 and the support frame 20a to perform a preliminary adjustment on the axial position of the support frame 20a through the second threaded adjustment members 51.

[0034] In one embodiment, if Figure 1 and 3 As shown, the support frame 20a is also provided with a plurality of supply and adjustment windows 22a at intervals along the circumferential direction, and the radial adjustment module 60 includes a plurality of adjustment blocks 61, each of which is provided with a wedge-shaped adjustment end 611, and each adjustment block 61 is used to be arranged at intervals in each supply and adjustment window 22a along the height direction of the supply and adjustment window 22a, and inserted between the rotor shaft system 10a and the support frame 20a through the wedge-shaped adjustment end 611 to adjust the rotor shaft system 10a and the support frame 20a. Specifically, after the adjustment of the support frame 20a is completed, the adjustment block 61 is inserted between the rotor shaft system 10a and the support frame 20a through the wedge-shaped adjustment end 611, and the adjustment block 61 is knocked to fine-tune the coaxiality of the rotor shaft system 10a and the support frame 20a, thereby ensuring the assembly accuracy of the rotor shaft system 10a and the support frame 20a.

[0035] In this embodiment, during the adjustment process, Figure 1 and 3 As shown, each supply and adjustment window 22a is arranged with six adjustment blocks 61, and each adjustment block 61 is separated on both sides of the supply and adjustment window 22a and is evenly spaced along the height direction of the supply and adjustment window 22a.

[0036] In this embodiment, four supply and adjustment windows 22a are provided, and the four supply and adjustment windows 22a are evenly spaced along the circumferential direction of the support frame 20a.

[0037] In this embodiment, each adjusting block 61 is further provided with a second lifting hole 612 , and the second lifting hole 612 facilitates the disassembly of the adjusting block 61 .

[0038] In one embodiment, if Figure 1 and 3 As shown, the assembly tool also includes a locking assembly 70, which is used to fix the assembled rotor shaft system 10a and the support frame 20a. Specifically, after the rotor shaft system 10a and the support frame 20a are assembled, the locking assembly 70 is connected to the rotor shaft system 10a and the support frame 20a to lock the rotor shaft system 10a and the support frame 20a, and then the assembled rotor shaft system 10a and the support frame 20a are removed from the frame to form a rotor shaft system 10a and the support frame 20a with high coaxiality.

[0039] In this embodiment, Figure 1 and 3 As shown, the locking assembly 70 includes a plurality of connecting rods 71, and the connecting rods 71 ​​are arranged in a staggered manner. Both ends of each connecting rod 71 are respectively fixedly connected to the rotor shaft system 10a and the support frame 20a, thereby locking the rotor shaft system 10a and the support frame 20a.

[0040] The embodiment of the present invention also provides a motor rotor assembly method, which is performed by a motor rotor assembly tool, such as Figure 4 As shown, the following steps are included: Assemble the rotor shaft system 10a to the inner positioning ring 20; Assemble the support frame 20a to the outer positioning ring 30; Connect the axial adjustment module 50 to the support base 10 and the support frame 20a to adjust the axial position of the support frame 20a; The axial positioning module 40 is fixedly connected to the rotor shaft system 10a and the support frame 20a to position the axial position of the support frame 20a; The radial adjustment module 60 is inserted between the rotor shaft system 10a and the support frame 20a to fine-tune the coaxiality of the rotor shaft system 10a and the support frame 20a.

[0041] Specifically, through the preliminary positioning of the coaxiality of the support seat 10 and the support frame 20a of the inner positioning ring 20 and the outer positioning ring 30, the preliminary adjustment of the axial position of the support frame 20a, the fine-tuning positioning, and the fine-tuning of the coaxiality of the support seat 10 and the support frame 20a, the assembly process can significantly reduce the assembly difficulty of the rotor shaft system 10a and the support frame 20a, and improve the assembly accuracy of the rotor shaft system 10a and the support frame 20a.

[0042] In one embodiment, in the step of connecting the support seat 10 and the support frame 20a by the axial adjustment module 50, each second threaded adjustment member 51 is threadedly connected to the support seat 10 and the support frame 20a to adjust the axial position of the support frame 20a.

[0043] In one of the embodiments, in the step of fixing the rotor shaft system 10a and the support frame 20a with the axial positioning module 40, each assembly part 41 is respectively engaged in each installation port 21a, and then the first threaded adjustment part 42 is threadedly connected to the assembly part 41 and the rotor shaft system 10a to position the axial position of the support frame 20a.

[0044] In one of the embodiments, in the step of inserting the radial adjustment module 60 between the rotor shaft system 10a and the support frame 20a, each adjustment block 61 is inserted between the rotor shaft system 10a and the support frame 20a through the wedge-shaped adjustment end 611 to fine-tune the coaxiality of the rotor shaft system 10a and the support frame 20a.

[0045] In order to better understand the present invention, the following Figures 1 to 3 The technical solution of the present invention is described in detail: during the assembly process of the support frame 20a and the motor rotor shaft system 10a, the motor rotor shaft system 10a is first installed on the inner positioning ring 20 of the support seat 10; the second threaded adjustment member 51 is installed on the upper chassis 11 of the support seat 10, and the second threaded adjustment member 51 is adjusted to an appropriate length; then the support frame 20a is hoisted above the motor rotor shaft system 10a, lowered and placed on the second threaded adjustment member 51, and the support frame 20a is supported and roughly adjusted in the axial direction by the second threaded adjustment member 51. After completing the axial rough adjustment of the support skeleton 20a, lift the assembly part 41, assemble it to the installation opening 21a in the circumferential direction of the support skeleton 20a, and engage it with the rotor shaft system 10a through the positioning stop, and then use the first threaded adjustment part 42 to fix the assembly part 41 and the motor rotor shaft system 10a to achieve axial fine adjustment and fixation of the support skeleton 20a; then insert each adjustment block 61 into the gap between the support skeleton 20a and the motor rotor shaft system 10a through the wedge-shaped adjustment end 611, and then use a measuring instrument to accurately measure the coaxiality of the support skeleton 20a and the motor rotor shaft system 10a, and according to the measurement results, use a rubber hammer to knock the wedge-shaped adjustment end 611 to fine-tune the coaxiality of the support skeleton 20a and the motor rotor shaft system 10a. Finally, the connecting rods 71 ​​at both ends of the support frame 20a are used to fix the support frame 20a and the rotor shaft system 10a, and the support frame 20a and the rotor shaft system 10a are locked, so that the assembly of the support frame 20a and the rotor shaft system 10a is completed.
