Description

Technical Field

[0001] This utility model relates to the field of motors, and in particular to a stator assembly device. Background Technology

[0002] In the field of motor manufacturing, the assembly quality of the stator directly affects the motor's operating efficiency and service life. Existing stator assembly devices typically use simple mechanical structures to install the yoke plates. This method has the following problems: due to the lack of an effective drive mechanism and transmission structure, it is difficult to achieve smooth movement and precise positioning of the yoke plates during installation. Manual operation is often required to adjust the position of the yoke plates, which not only increases the labor intensity of the operators but also easily causes installation deviations of the yoke plates.

[0003] Currently, some stator assembly devices use screw connections to fix the magnetic yoke plates with attached magnets to the support plate, and control the distance between the magnetic yoke plates via handwheels to assemble the U-shaped stator. However, this structure still has shortcomings. These mainly include: the lack of a reliable linkage mechanism between the fixed plate and the moving plate in existing devices, making the magnetic yoke plates prone to positional shifts during installation; and the significant attraction between the magnets during assembly, which can cause the two magnetic yoke plates to instantly attract each other, affecting assembly accuracy and potentially creating safety hazards. These problems seriously impact the quality, efficiency, and operational safety of stator assembly. Utility Model Content

[0007] Furthermore, the driving component is a lead screw, and the mating component is a nut connector, with the lead screw and the nut connector being threadedly engaged.

[0008] Furthermore, an end cap is provided on the end of the base away from the fixed plate, and the lead screw is rotatably connected to the end cap.

[0009] Furthermore, a buffer is provided between the movable plate and the end cap.

[0010] Furthermore, it also includes a guide assembly, which includes a slide rail disposed on the base and slide blocks disposed on the movable plate and located on both sides of the nut connector, the slide blocks being slidably engaged with the slide rail.

[0011] Furthermore, a handwheel is provided at the end of the lead screw away from the fixed plate. Rotating the handwheel drives the lead screw to rotate, thereby driving the moving plate to reciprocate relative to the fixed plate.

[0013] Furthermore, the mounting assembly includes a plurality of first mounting members located on the fixed plate and the movable plate, and a plurality of second mounting members located on the movable plate; both the first mounting members and the second mounting members have a snap-fit ​​structure; the fixed plate fixes the first magnetic yoke plate through the first mounting members; the movable plate fixes the second magnetic yoke plate through the cooperation of the first mounting members and the second mounting members.

Obviously, the described embodiments are only a part of the embodiments of this utility model, not all of them. Other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are all within the scope of protection of this utility model. Furthermore, all connections / linkages involved in the patent do not simply refer to direct contact between components, but rather to the ability to form a better connection structure by adding or reducing connecting accessories according to specific implementation conditions.

[0037] Reference Figure 1-3 A stator assembly device includes a base 10 and a fixed plate 20 and a movable plate disposed at both ends of the base 10. A drive assembly 40 includes a rotation drive component 41 and a mating component 42 that drives the rotation drive component 41, the mating component 42 being fixedly connected to the movable plate 30. An mounting assembly 50 is disposed on one side opposite the fixed plate 20 and the movable plate 30, for mounting a magnetic yoke plate 60. The rotation drive component 41 drives the movable plate 30 to reciprocate relative to the fixed plate 20.

[0038] Understandably, the base 10 provides stable support, with a fixed plate 20 and a movable plate 30 respectively installed at both ends of the base 10. The fixed plate 20 remains in a fixed position, while the movable plate 30 can move along the direction of the base 10. The rotation drive component 41 in the drive assembly 40 forms a transmission structure with the mating component 42. The mating component 42 is connected to the movable plate 30 via a fixed connection. When the rotation drive component 41 rotates, it drives the movable plate 30 to reciprocate through the transmission engagement with the mating component 42. An installation assembly 50 is provided on the opposite side of the fixed plate 20 and the movable plate 30 for installing the magnetic yoke plate 60. As the movable plate 30 reciprocates, the distance between it and the fixed plate 20 can be adjusted, thereby achieving the required spacing adjustment during stator assembly.

[0039] For example, when the stator yoke plate 60 needs to be installed onto the mounting assembly 50, the moving plate 30 can be moved away from the fixed plate 20 by rotating the drive component 41, thereby obtaining sufficient operating space to facilitate the installation of the yoke plate 60. After the yoke plate 60 is installed, the moving plate 30 can be moved towards the fixed plate 20 by rotating the drive component 41, so that the yoke plate 60 reaches the predetermined assembly position, completing the stator assembly operation. This structural design makes the stator assembly process more precise and controllable, while ensuring the stability and reliability of the assembly process.

[0040] In some embodiments, refer to Figure 1-3 In a specific embodiment of the drive assembly 40, the rotation drive component 41 adopts a lead screw structure, and the mating component 42 adopts a nut connector. The lead screw and the nut connector are connected by a threaded engagement. When the lead screw rotates, due to the threaded engagement, the nut connector will move along the axial direction of the lead screw, thereby driving the movable plate 30 fixedly connected to it to reciprocate. For example, when assembling the stator, the position of the movable plate 30 can be precisely controlled by rotating the lead screw, so that the magnetic yoke plate 60 reaches the required assembly position.

[0041] In some embodiments, refer to Figure 1 , 3 During the stator assembly process, when the moving plate 30 moves to the end position, a buffer 80 is set between the moving plate 30 and the end cover 70. This buffer can play a role in buffering and shock absorption during the movement of the moving plate 30, avoiding direct collision between the moving plate 30 and the end cover 70. The buffer 80 can absorb the impact force.

[0042] Furthermore, the buffer 80 can be made of rubber pads or rubber blocks of appropriate hardness.

[0043] In some embodiments, refer to Figure 1 The system also includes a guide assembly 90, which comprises a slide rail 91 mounted on the base 10 and slide blocks 92 mounted on the movable plate 30 and located on both sides of the nut connector. The slide blocks 92 are slidably engaged with the slide rail 91. During stator assembly, when the lead screw drives the movable plate 30 to reciprocate, the sliding engagement of the slide blocks 92 on the slide rail 91 prevents the movable plate 30 from deviating or wobbling, thereby ensuring the assembly accuracy and positional precision of the magnetic yoke plate 60.

[0044] In some embodiments, a handwheel 411 is provided at the end of the lead screw away from the fixed plate 20. By manually turning the handwheel 411, the lead screw can be rotated. The rotation of the lead screw, through the threaded engagement with the nut connector, drives the moving plate 30 to reciprocate relative to the fixed plate 20. For example, when assembling the stator, the operator can manually turn the handwheel 411 to precisely control the position of the moving plate 30, making it slowly approach or move away from the fixed plate 20, thereby achieving precise adjustment of the installation position of the magnetic yoke plate 60. This manual operation method has the advantages of high control precision and simple operation.

[0045] Furthermore, in addition to manual operation, the stator assembly device can also use a servo motor as a power source to drive the lead screw to rotate. The servo motor can provide more precise and automated control. By rotating the servo motor, the lead screw can be driven to rotate, thereby realizing the reciprocating motion of the moving plate 30. For example, during the stator assembly process, the speed and displacement parameters of the servo motor can be set to achieve automated and precise positioning of the moving plate 30. This electric drive method not only improves work efficiency, but also ensures the consistency and repeatability of each assembly process, making it particularly suitable for mass production scenarios.

[0046] In some embodiments, refer to Figure 1 , 5 The mounting assembly 50 uses mounting holes 51 on the fixed plate 20 and the movable plate 30 respectively. The magnetic yoke plate 60 is firmly fixed to the fixed plate 20 or the movable plate 30 by using fasteners (such as bolts, screws, etc.) through these mounting holes 51. For example, during the stator assembly process, the operator can first install one magnetic yoke plate 60 on the mounting hole 51 of the fixed plate 20 with fasteners, and then fix the other magnetic yoke plate 60 on the mounting hole 51 of the movable plate 30 with fasteners. This installation method is not only convenient for installation and disassembly, but also ensures the stability and reliability of the installation of the magnetic yoke plate 60, and ensures the accuracy of the assembly process.

[0047] In some embodiments, continue to refer to Figure 1 , 5 The mounting assembly 50 consists of multiple first mounting members 52 disposed on the fixed plate 20 and the movable plate 30, and multiple second mounting members 53 disposed on the movable plate 30. Both the first mounting members 52 and the second mounting members 53 have a snap-fit ​​structure 54. The first magnetic yoke plate 60 can be fixed to the fixed plate 20 by means of the first mounting members 52, while the second magnetic yoke plate 60 needs to be fixed by means of the first mounting members 52 and the second mounting members 53 on the movable plate 30. For example, during the stator assembly process, the operator first snaps the first magnetic yoke plate 60 with the first mounting members 52 on the fixed plate 20, and then double snaps the second magnetic yoke plate 60 with the first mounting members 52 and the second mounting members 53 on the movable plate 30. This snap-fit ​​structure 54 design not only simplifies the installation process and eliminates the need for additional fasteners, but also ensures the firmness and positioning accuracy of the magnetic yoke plate 60 installation.

[0048] Furthermore, refer to Figure 1 , 34, 5, and multiple first mounting pieces 52 are horizontally arranged along the bottom of the fixed plate 20 and the movable plate 30, while the second mounting pieces 53 are located on both sides of the movable plate 30. The fixed plate 20 only has the bottom first mounting pieces 52, so that when installing the first magnetic yoke plate 60, there is no lateral restriction, allowing for the adaptation of magnetic yoke plates 60 of different lengths, as long as the bottom of the magnetic yoke plate 60 engages with the snap-fit ​​structure 54 of the first mounting piece 52. The movable plate 30, on the other hand, has both the bottom first mounting pieces 52 and the second mounting pieces 53 on both sides of the lateral direction. This three-part... The surface constraint fixing method requires that the second magnetic yoke plate 60 installed on the moving plate 30 must meet specific length requirements. For example, during the stator assembly process, the operator can select different lengths of the first magnetic yoke plate 60 to install on the fixed plate 20 according to actual needs. However, when installing the second magnetic yoke plate 60, a fixed length magnetic yoke plate 60 that matches the distance between the first mounting part 52 and the second mounting part 53 on the moving plate 30 must be selected. This design ensures both the flexibility and adaptability of the device and the precise positioning and stability of the magnetic yoke plate 60 during the stator assembly process.

[0049] In some embodiments, refer to Figure 1-5 The overall structure is supported by fixing the mating part 42 to the mounting plate 100. The movable plate 30 adopts a single-sided fixing design, that is, one side of the movable plate 30 is fixedly connected to the side of the mounting plate 100 near the fixed plate 20. On the other side of the movable plate 30, multiple first reinforcing ribs 110 are provided to enhance the structural strength. Correspondingly, multiple second reinforcing ribs 120 are also provided on the side of the fixed plate 20 away from the movable plate 30. For example, during the stator assembly process, when it is necessary to install or adjust the position of the magnetic yoke plate 60, these reinforcing rib structures can effectively prevent the movable plate 30 and the fixed plate 20 from deforming or displacing due to force, ensuring that the relative positions between the components remain stable throughout the assembly process. Especially when installing first magnetic yoke plates 60 of different lengths or second magnetic yoke plates 60 of fixed length, the supporting effect of the reinforcing ribs can provide sufficient structural rigidity to ensure the installation accuracy and assembly quality of the magnetic yoke plate 60.

[0050] Furthermore, the buffer 80 is disposed on the mounting plate 100, facing the end cap 70. The above is a detailed description of the preferred embodiment of this utility model, but the present utility model is not limited to the described embodiment. Those skilled in the art can make various equivalent modifications or substitutions without departing from the spirit of this utility model, and these equivalent modifications or substitutions are all included within the scope defined by the claims of this application.
