[0043] Please see Figure 1 and Figure 2 This utility model provides a stator clamping mechanism 100, including a lower limit seat 140, an upper limit seat 120, a rotating disk 130, multiple clamping members 110 and a rotating drive member 150.

[0044] Combination Figure 2 and Figure 3 The upper limit seat 120 is fixed to the lower limit seat 140. The upper limit seat 120 is provided with a relief groove 121 and a plurality of limit grooves 122. The relief groove 121 and the limit grooves 122 penetrate the upper limit seat 120 along the axial direction L. The plurality of limit grooves 122 are distributed circumferentially along the relief groove 121. The limit grooves 122 extend radially and are connected to the relief groove 121.

[0045] Combination Figure 2 and Figure 4 The rotating disk 130 is rotatably disposed between the upper limit seat 120 and the lower limit seat 140, and the rotating disk 130 is provided with a plurality of guide grooves 131.

[0046] Combination Figures 2-5 The clamping member 110 is slidably connected to the corresponding limiting groove 122 in the radial direction. The clamping member 110 is used to clamp the segmented stator 300. The bottom of the clamping member 110 is embedded in the guide groove 131. When the rotating disk 130 rotates, the side wall of the guide groove 131 can push the clamping member 110 to move.

[0047] The rotary drive 150 is connected to the rotary disk 130 and is used to drive the rotary disk 130 to rotate so as to drive the clamping member 110 to slide along the limiting groove 122 through the guide groove 131.

[0048] When the rotating disk 130 rotates in the first direction, the sidewall of the guide groove 131 pushes the bottom of the clamping member 110, causing the clamping member 110 to move relative to the sidewall of the guide groove 131. The limiting groove 122 restricts the movement of the clamping member 110 to radially inward. In this way, the multiple clamping members 110 contract radially to make the segmented stator 300 form a circle. Conversely, when the rotating disk 130 rotates in the second direction, the sidewall of the guide groove 131 pushes the bottom of the clamping member 110, causing the clamping member 110 to move relative to the sidewall of the guide groove 131. The limiting groove 122 restricts the movement of the clamping member 110 to radially outward. In this way, the multiple clamping members 110 expand radially.

[0049] It should be noted that the first direction and the second direction are opposite. For example, the first direction can be clockwise and the second direction can be counterclockwise; or, the first direction can be counterclockwise and the second direction can be clockwise.

[0050] Compared with the prior art, the beneficial effects of this utility model are as follows: the segmented stator 300 is fixed on the clamping member 110 by manual labor or a robotic arm, and the rotating disk 130 is driven to rotate in the first direction by the rotation drive member 150, so that the multiple clamping members 110 shrink radially to make the segmented stator 300 form a circle; the stator after being circled is removed, and the rotating disk 130 is driven to rotate in the second direction by the rotation drive member 150, so that the multiple clamping members 110 unfold radially to restore the initial position. There is no need to assemble the circle manually, thereby reducing manpower and improving efficiency.

[0051] It is worth mentioning that the clearance groove 121 extends through the upper limit seat 120 along the axial direction L, which can avoid interfering with the radial inward movement of the clamping member 110. It can be compatible with the assembly of stators with various outer diameters, improve the versatility of the mechanism, and reduce the cost of changing models.

[0052] In one embodiment of this application, please refer to Figure 6 At the same time, combined Figures 2-4 The clamping member 110 includes a clamping base 111 and a clamping top seat 112. The top of the clamping base 111 is slidably embedded in the limiting groove 122. The clamping top seat 112 is located on the side of the upper limit seat 120 away from the rotating disk 130. The clamping top seat 112 is fixedly connected to the top of the clamping base 111. The width of the clamping top seat 112 is greater than the width of the limiting groove 122.

[0053] In this embodiment, the design of the clamping top seat 112 being wider than the limiting groove 122 forms a mechanical limit. When the clamping base 111 slides within the limiting groove 122, the clamping top seat 112 remains locked on the surface of the upper limit seat 120, effectively preventing the clamping member 110 from dislodging from the limiting groove 122 during radial movement, thus improving the reliability of the mechanism's operation. The sliding engagement between the clamping base 111 and the limiting groove 122 achieves a radial guiding function, while the clamping top seat 112 simultaneously serves as the stator clamping surface. The clamping top seat 112, positioned above the upper limit seat 120, forms an axial L-shaped clamping force. Combined with the sliding of the clamping base 111 within the limiting groove 122, this constitutes a three-dimensional constraint (radial constraint by the limiting groove 122, axial L-shaped clamping by the top seat), preventing the clamping member 110 from shifting under vibration and ensuring the positional accuracy during stator assembly. In addition, the clamping component 110 is designed as a split structure. The split structure allows the clamping base 111 and the top seat to be made of different materials (such as wear-resistant copper alloy for the base and high-strength steel for the top seat). Through subsequent assembly and fixation, it not only reduces the processing difficulty, but also achieves the optimal combination of material properties and extends the service life of key components.

[0054] In one embodiment of this application, such as Figure 5 and Figure 6As shown, the clamping member 110 has a clamping groove 114 at one end radially close to the relief groove 121. The clamping groove 114 is used to fix the segmented stator 300.

[0055] Specifically, such as Figure 6 As shown, the clamping member 110 also includes a fixing member 113, which is fixedly connected to the top of the clamping base 111. The fixing member 113 is spaced apart on the side of the clamping top seat 112 near the clearance groove 121. The clamping top seat 112, the clamping base 111, and the fixing member 113 together form a clamping groove 114. In this structure, by adjusting the interval between the fixing member 113 and the clamping top seat 112, the width of the clamping groove 114 can be adapted to different specifications of segmented stators 300, improving the versatility of the mechanism and reducing the cost of changing models.

[0056] In one embodiment of this application, combined with Figure 2 , Figure 4 and Figure 6 A guide wheel 115 is rotatably connected to the bottom of the clamping base 111, and the guide wheel 115 rolls in contact with the side wall of the guide groove 131. This structure can reduce motion friction and improve transmission efficiency; the guide wheel 115 has a higher tolerance for minor misalignment or surface roughness of the side wall of the guide groove 131, and compared with direct sliding fit, it can reduce the machining accuracy requirements of the rotating disk 130 and the clamping part 110, and reduce manufacturing costs.

[0057] In one embodiment of this application, such as Figure 4 As shown, the guide groove 131 is arc-shaped and extends through the rotary disk 130 along the axial direction L. The arc-shaped guide groove 131 can more naturally guide the radial movement of the clamping part 110, ensuring a smooth transition during contraction or expansion, avoiding jamming or impact that may be caused by rigid linear motion, thereby improving the assembly accuracy and coaxiality of the segmented stator 300. The guide groove 131 extends through the rotary disk 130 along the axial direction L, allowing for one-time forming using processes such as wire cutting or milling, reducing manufacturing costs; it also facilitates cleaning and maintenance, preventing the accumulation of debris or oil that may affect motion accuracy.

[0058] In one embodiment of this application, such as Figure 2 As shown, the lower limit seat 140 has a rotating groove 141 and a step 142 on the side near the upper limit seat 120. The step 142 is located around the rotating groove 141, and the rotating disk 130 is rotatably mounted in the rotating groove 141. The upper limit seat 120 is mounted on the step 142. Through the cooperation of the rotating groove 141 and the step 142, the rotating disk 130 is accurately positioned, stably operated, and easily assembled. At the same time, the load-bearing capacity and durability of the mechanism are enhanced, making it suitable for high-precision and high-efficiency stator assembly operations and meeting the needs of automated production.

[0059] In one embodiment of this application, such as Figure 2 As shown, the bottom of the rotating slot 141 is provided with a rotating hole 1411. The output end of the rotating drive component 150 passes through the rotating hole 1411 and is fixedly connected to the bottom of the rotating disk 130. The output end of the rotating drive component 150 is directly driven through the rotating hole 1411, that is, the output end of the rotating drive component 150 (such as a motor or reducer) is directly rigidly connected to the rotating disk 130 through the rotating hole 1411, avoiding the use of intermediate transmission mechanisms such as belts and gears, reducing energy loss in the power transmission process, and improving driving efficiency. The rotating drive component 150 and the rotating disk 130 adopt a direct connection layout, which eliminates the need for additional transmission components, improves the compactness and load capacity of the structure, and is suitable for high-precision and high-reliability stator automated assembly equipment, meeting the dual requirements of efficiency and stability in modern intelligent manufacturing. In addition, the rotating hole 1411 design allows the rotating drive component 150 to be directly installed from below the lower limit seat 140, simplifying the assembly process. At the same time, the maintenance or replacement of the rotating drive component 150 does not require disassembling the rotating disk 130 or the upper limit seat 140, reducing maintenance difficulty.

[0060] Please see Figure 7 At the same time, combined Figures 1-6 The present invention also provides a transport device, including a transfer mechanism 200 and a stator clamping mechanism 100 as described above, wherein the transfer mechanism 200 is used to transfer the stator clamping mechanism 100.

[0061] The segmented stator 300 is fixed to the clamping member 110 by manual labor or a robotic arm. The rotary drive 150 drives the rotary disk 130 to rotate in the first direction, causing the multiple clamping members 110 to retract radially to form a circle of the segmented stator 300. Subsequently, the transfer mechanism 200 transfers the stator clamping mechanism 100 to the next station, and the multiple segmented stators 300 after being formed can be removed from the next station. The transfer mechanism then transfers the stator clamping mechanism 100 to the initial station, and the rotary drive 150 drives the rotary disk 130 to rotate in the second direction, causing the multiple clamping members 110 to unfold radially to restore their initial positions. This eliminates the need for manual formation, thereby reducing manpower and improving transportation efficiency.

[0062] In one embodiment of this application, combined with Figure 7 and Figure 8The transfer mechanism 200 includes a support member 210, a slide rail 220, a slider 230, a connector 240, and a transfer drive member 250. The slide rail 220 is mounted on the support member 210, and the slider 230 is slidably connected to the slide rail 220. The connector 240 is fixedly connected to the slider 230, and the stator clamping mechanism 100 is fixed to the connector 240. The transfer drive member 250 is connected to the connector 240 and drives the connector 240 to move along the slide rail 220. The precise fit between the slide rail 220 and the slider 230 ensures that the stator clamping mechanism 100 maintains stable operation during transfer, avoiding positioning deviations caused by vibration.

[0063] In one embodiment of this application, combined with Figure 2 , Figure 7 and Figure 8 The lower limit seat 140 is mounted on the connector 240, and the rotary drive 150 is located at the bottom of the lower limit seat 140. The connector 240 has a clearance opening 241, and the support 210 has a sliding groove 211. The rotary drive 150 extends below the support 210 through the clearance opening 241 and the sliding groove 211. The rotary drive 150 adopts a recessed layout, which partially houses the rotary drive 150 under the support 210, thereby reducing the height of the equipment and achieving a compact layout.

[0064] In the embodiments of this application, the rotary drive 150 may be, but is not limited to, a motor, and the transfer drive 250 may be, but is not limited to, a linear motor.
