[0018] The following is a further detailed description of specific embodiments of the present invention. It should be understood that the description of the embodiments of the present invention herein is not intended to limit the scope of protection of the present invention.

[0019] like Figure 1 , which is a schematic structural diagram of the high-speed rotor assembly mechanism provided by the present invention. The high-speed rotor assembly mechanism includes a frame 10, a rotating lifting assembly 20 disposed on the frame 10, a clamping assembly 30 disposed at the output end of the rotating lifting assembly 20, two pitch adjustment assemblies 40 disposed on either side of the clamping assembly 30, and two mounting assemblies 50 disposed on the two pitch adjustment assemblies 40. It is conceivable that the high-speed rotor assembly mechanism also includes other functional modules, such as a power supply module, a robotic arm module, etc., which are well known to those skilled in the art and will not be described in detail here.

[0020] Please also refer to Figures 2 to 5 It should be noted that the high-speed rotor assembly mechanism is used to install at least twelve insulating frames 70 at intervals on the circumferential outer wall of a stator core 60. The stator core 60 is a hollow ring, the hollow portion of which is sleeved on the clamping assembly 30, thereby achieving internal support and fixation of the stator core 60. At least twelve iron teeth 61 are protruded from the circumferential outer wall of the stator core 60 at intervals. The insulating frame 70 is provided with a square hole 71 that matches the iron teeth 61. In this way, the high-speed rotor assembly mechanism creates an interference fit between the square hole 71 and the iron teeth 61, completing the assembly operation.

[0021] The structure of the frame 10 is determined by actual needs, and is used to carry various components so that they can be coordinated with each other, thereby completing the assembly operation between the stator core 60 and the insulating frame 70 .

[0022] The rotating lifting assembly 20 can drive the clamping assembly 30 to rotate or lift, thereby cooperating with the two installation assemblies 50 to assemble the stator core 60 clamped on the clamping assembly 30. Specifically, the two installation assemblies 50 are arranged on both sides of the clamping assembly 30. After the two insulating skeletons 70 are installed on the corresponding iron tooth parts 61 on both sides of the stator core 60, the rotating lifting assembly 20 drives the clamping assembly 30 to rotate 30 degrees, thereby installing the next two insulating skeletons 70 and the iron tooth parts 61. After completing the installation of the 12 insulating skeletons 70, the rotating lifting assembly 20 drives the clamping assembly 30 to rise, so as to cooperate with the external robotic arm module to take away the product. The structure and working principle of the rotating lifting assembly 20 itself are existing technologies and will not be described in detail here.

[0023] The clamping assembly 30 includes an expansion sleeve 31, an internal support cylinder 32 arranged on one side of the expansion sleeve 31, an internal expansion core 33 arranged at the output end of the internal support cylinder 32, and at least four expansion blocks 34 inserted at intervals on the circumferential outer side wall of the expansion sleeve 31.

[0024] The internal expansion core 33 is movably disposed within the expansion sleeve 31 and abuts against the four expansion blocks 34. The end of the internal expansion core 33 is conical, and the abutment surfaces of the four expansion blocks 34 and the internal expansion core 33 are arranged at an angle. As a result, when the internal support cylinder 32 drives the internal expansion core 33 to move and compress the four expansion blocks 34, the four expansion blocks 34 gradually move toward the outside of the expansion sleeve 31, thereby performing an external support operation to secure the stator core 60.

[0025] The clamping assembly 30 also includes at least two rubber rings 35 distributed and sleeved on both ends of the expansion block 34. The rubber ring 35 can gradually expand when the four expansion blocks 34 are pushed outward by the internal expansion core 33. In this way, after the internal support cylinder 32 is depressurized, the rubber ring 35 releases the deformation and shrinks inward, thereby making the four expansion blocks 34 approach each other and quickly return to the initial position to wait for the next internal support operation.

[0026] The distance adjustment assembly 40 includes a first guide rail 41 arranged on the frame 10, a first cylinder 42 arranged at one end of the first guide rail 41, a first base plate 43 slidably arranged on the first guide rail 41, two second guide rails 44 respectively arranged in parallel on both sides of the first guide rail 41, two second cylinders 45 respectively arranged at one end of the second guide rail 44, and two second base plates 46 respectively arranged on the two second cylinders 45.

[0027] The length direction of the first and second guide rails 41 and 44 is perpendicular to the axial direction of the rotating lifting assembly 20. The first and second cylinders 42 and 45 are respectively arranged on the side of the first and second guide rails 41 and 44 away from the clamping assembly 30. The first and second cylinders 42 and 45 can respectively drive the first and second base plates 43 and 46 to reciprocate on the first and second guide rails 41 and 44. The mounting assembly 50 is arranged on the first and second base plates 43 and 46. In this way, the spacing between the mounting assembly 50 and the clamping assembly 30 can be changed by driving the first and second cylinders 42 and 45, thereby adjusting the assembly specifications of the stator core 60 to improve the applicability of the mechanism. In addition to performing the distance adjustment operation, the first cylinder 42 can cooperate with the mounting assembly 50 to complete the installation operation. The specific cooperation and the specific configuration of the mounting assembly 50 will be described below.

[0028] The mounting assembly 50 includes a pushing cylinder 51, a push plate 52 arranged at the output end of the pushing cylinder 51, at least four guide rods 53 arranged on the push plate 52, a material receiving block 54 arranged on one side of the pushing cylinder 51, a pushing block 55 movably sleeved on the material receiving block 54, two clamping cylinders 56 respectively arranged on both sides of the material receiving block 54, and two clamping blocks 57 respectively arranged at the output ends of the two clamping cylinders 56.

[0029] The output direction of the push cylinder 51 is toward the material receiving block 54 and is parallel to the length of the first guide rail 41. The push cylinder 51 is capable of driving the push plate 52 and causing the four guide rods 53 to reciprocate toward the material receiving block 54. The four guide rods 53 are movably mounted on the material receiving block 54, and the ends of the four guide rods 53 away from the push plate 52 are fixedly connected to the push block 55. In this way, the push cylinder 51 can drive and move the push block 55. A spring 58 is respectively provided on the four guide rods 53, one end of the spring 58 is in contact with the push plate 52, and the other end is in contact with the side of the receiving block 54 away from the pushing block 55, so that when the pushing cylinder 51 drives the pushing plate 52 to move toward the receiving block 54, the spring 58 is compressed and stores elastic potential energy, and when the pushing cylinder 51 is depressurized, the spring 58 releases the elastic potential energy, so that the pushing plate 52 drives the pushing block 55 to quickly reset to wait for the next pushing and installation operation.

[0030] The two clamping cylinders 56 are respectively disposed on the two second base plates 46, with the output directions of the two clamping cylinders 56 facing each other. A supporting groove for accommodating the insulating frame 70 is provided on the opposite sides of the two clamping blocks 57. In this manner, the two clamping cylinders 56 can respectively drive the two clamping blocks 57 to move toward each other, thereby clamping the insulating frame 70. The clamping position of the two clamping blocks 57 is located on the side of the first base plate 43 facing the material receiving block 54, and is located between the material receiving block 54 and the clamping assembly 30.

[0031] The pushing cylinder 51 and the material receiving block 54 are both fixedly arranged on the first base plate 43. A material receiving portion 59 is provided on the side of the material receiving block 54 away from the pushing cylinder 51. The material receiving portion 59 is in the shape of a long block as a whole, which can be inserted into the square hole portion 71 on the insulating frame 70. The pushing block 55 is movably mounted on the material receiving portion 59. In this way, when performing the assembly operation, the first cylinder 42 drives the first base plate 43 to move toward the clamping assembly 30. During the movement, the material receiving portion 59 is inserted into the insulating frame 70 clamped by the two clamping blocks 57, and the two clamping cylinders 56 drive the two clamping blocks 57 to move away from each other. The first cylinder 42 continues to drive the first base plate 43 to move toward the clamping assembly 30 until the side wall of the material receiving portion 59 abuts against the side wall of the iron tooth portion 61 on the stator core 60. Then, the pushing cylinder 51 drives the pushing plate 52 and drives the pushing block 55 to move, pushing the insulating frame 70 onto the stator core 60 to complete the interference fit between the square hole portion 71 and the iron tooth portion 61, thereby completing the assembly operation.

[0032] Compared with the prior art, the high-speed rotor assembly mechanism provided by the present invention supports the stator core 60 through the clamping assembly 30, and drives the pushing block 55 under the drive of the pushing cylinder 51 to push the insulating skeleton 70 sleeved on the connecting portion 59 onto the stator core 60, so as to complete the interference fit between the square hole portion 71 and the iron tooth portion 61, thereby completing the assembly operation. The high-speed rotor assembly mechanism can quickly and efficiently complete the assembly of the stator core 60 and the insulating skeleton 70, without the need for manual participation throughout the process, with a high degree of automation, and is suitable for assembly line production. The mechanism can complete the assembly of the stator core 60 and the insulating skeleton 70 of different specifications by replacing the specifications of the connecting block 54 and the pushing block 55, in cooperation with the spacing adjustment assembly 40, and has high applicability.

[0033] The above are only preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Any modifications, equivalent replacements or improvements within the spirit of the present invention are included in the scope of the claims of the present invention.
