Description

Technical Field

[0001] This application belongs to the technical field of stator and rotor manufacturing, and specifically relates to a stacking mold for stator and rotor manufacturing. Background Technology

[0002] An electric motor is a device that converts electrical energy into mechanical energy. It is widely used in various equipment and systems. The composition of an electric motor is relatively complex, but it mainly consists of a stator and a rotor. The stator and rotor work together through the action of magnetic coils to convert electromagnetic energy into mechanical energy. Both the stator and rotor are made of a certain number of silicon steel sheets of the same shape stacked together. Adjacent silicon steel sheets are usually connected by welding or riveting.

[0003] Currently, in the production of stators and rotors, robotic arms are used to stack silicon steel sheets together to fix adjacent silicon steel sheets together. However, when the robotic arms place the silicon steel sheets, the silicon steel sheets may come into contact with the inner wall of the mold. This causes the inner wall of the mold to block the silicon steel sheets, preventing them from moving into place. Consequently, the upper silicon steel sheets cannot fully adhere to the lower silicon steel sheets, resulting in uneven thickness of the stators and rotors, which in turn affects the production quality of the stators and rotors. Utility Model Content

[0004] This application provides a stacking mold for stator and rotor production to solve at least one of the above-mentioned technical problems.

[0005] The technical solution adopted in this application is as follows:

[0006] A stacking die for stator and rotor production, comprising:

[0007] Connecting seat, the connecting seat having a central hole;

[0008] A receiving seat having a through hole extending through it along its own axial direction, the through hole forming a receiving space for accommodating a silicon steel sheet, and the receiving seat passing through the central hole;

[0009] A stop member, the stop member being connected to the connecting seat, and one end of the connecting seat extending into the receiving space;

[0010] A driving structure is provided for driving the receiving seat to rotate, and when the receiving seat rotates relative to the connecting seat, the stop member moves toward the outside of the receiving seat.

[0011] By adopting the above technical solution, when using the stacking mold in this application, the robot places the silicon steel sheet in the accommodating space so that the stop member blocks the silicon steel sheet located at the bottom layer, so that the silicon steel sheet stays stably in the accommodating space, and multiple silicon steel sheets are stacked in the accommodating space. When a certain number of silicon steel sheets are stacked or after one silicon steel sheet is placed in the accommodating space, the driving structure drives the accommodating seat, which then rotates the accommodating seat and the connecting seat relative to each other by a certain angle. At this time, the silicon steel sheet that is in contact with the wall of the through hole slides relative to the wall of the through hole under the rotation of the accommodating seat, so that two adjacent silicon steel sheets are completely attached. This avoids the influence of uneven workpiece thickness caused by the stamping of silicon steel sheets on the overall thickness of the stator and rotor, thereby ensuring the uniformity of the thickness of the stator and rotor, and thus ensuring the production quality of the stator and rotor.

[0012] In addition, when the receiving seat and the connecting seat rotate relative to each other, the stop member moves outward of the receiving seat under the action of the connecting seat and the receiving seat. After the silicon steel sheets are stacked to the required number, the stop member moves to the outside of the silicon steel sheets, so that the stop member and the bottom of the silicon steel sheets can avoid each other. This allows the stacked silicon steel sheets to fall through the bottom opening of the through hole, thereby releasing the stacked silicon steel sheets so that the workers can carry out the next step of processing. This greatly improves the production efficiency of the stator and rotor.

[0013] Optionally, the stop member has a connecting section and a stop section, the stop section passing through the receiving seat, the connecting seat having an arcuate groove extending circumferentially thereon, the distance between the arcuate groove and the wall of the central hole gradually increasing circumferentially along the connecting seat, and the connecting section passing through the arcuate groove.

[0014] By adopting the above technical solution, since the distance between the arc-shaped groove and the wall of the central hole gradually increases along the circumference of the connecting seat, and the connecting section passes through the arc-shaped groove, when the receiving seat and the connecting seat rotate relative to each other, the stop member can rotate with the receiving seat under the action of the stop section. This causes the connecting section of the stop member to slide relative to the arc-shaped groove, so that the stop member moves towards the outside of the receiving seat under the relative rotation of the receiving seat and the connecting seat. As the number of silicon steel sheets stacked together increases, the stop-stopping area between the stop section and the silicon steel sheets decreases. Finally, when the required number of silicon steel sheets are stacked, the stop section releases its stop-stopping engagement with the silicon steel sheets, allowing the stacked silicon steel sheets to fall through the bottom opening of the through hole. In addition, the groove wall of the arc-shaped groove can also limit the stop member to prevent the stop member from rotating under the gravity of the silicon steel sheets, thereby increasing the support stability of the stop member for the silicon steel sheets.

[0015] Optionally, the arcuate groove passes through the connecting seat axially, the receiving seat is provided with a through port, the stop section passes through the through port, and the receiving seat is provided with an elastic member acting on the stop section, the elastic member being able to apply an upward elastic force to the stop section.

[0016] By adopting the above technical solution, since the arc-shaped groove passes through the connecting seat axially, and the receiving seat is provided with a through-hole, the stop section passes through the through-hole, and the receiving seat is provided with an elastic element acting on the stop section, the stop section can elastically move in the axial direction of the receiving seat according to the change in the number of silicon steel sheets. On the one hand, it reduces the distance that the silicon steel sheets need to move when they are placed in the receiving space, so as to reduce the phenomenon that the silicon steel sheets may come into contact with the hole wall of the through hole and become offset, thereby further ensuring the uniformity of the thickness of the stator and rotor. On the other hand, it realizes that as the number of silicon steel sheets placed above the stop section gradually increases, the stop section moves downward elastically to ensure that the required number of silicon steel sheets can be placed in the receiving space, so as to ensure the production quality of the stator and rotor.

[0017] Optionally, the elastic element is a spring sleeved outside the receiving seat, the receiving seat having a support portion located at the bottom of the spring to support the spring.

[0018] By adopting the above technical solution, since the support part is located at the bottom of the spring, it can support the spring, thereby increasing the elastic support effect of the spring on the stop section. Furthermore, the spring is sleeved outside the receiving seat, allowing it to avoid interfering with the falling of the silicon steel sheet within the receiving space, thus ensuring the stacking efficiency of the silicon steel sheet. Moreover, because the spring is sleeved outside the receiving seat, the receiving seat can also guide the deformation of the spring, increasing the stability of the spring during deformation.

[0019] Optionally, the elastic element is a spring disposed in the passage, with one bottom end of the spring contacting the wall of the passage and one top end of the spring contacting the bottom of the stop section.

[0020] By adopting the above technical solution, since the elastic element is a spring located in the passage, the elastic element can avoid the outer peripheral surface of the receiving seat, thereby avoiding the requirement for the gap between the receiving seat and the connecting seat due to the spring being located outside the receiving seat, thus reducing the assembly difficulty of the receiving seat and improving the assembly efficiency of the stacking mold.

[0021] Optionally, a positioning post is provided on the wall of the passage, and the spring is sleeved on the positioning post.

[0022] By adopting the above technical solution, since the spring is sleeved on the positioning post, the positioning post can position the spring to avoid the phenomenon that the spring may separate from the positioning post, thereby increasing the connection stability between the spring and the through port, and reducing the difficulty of installing the spring, so as to further improve the assembly efficiency of the stacked mold.

[0023] Optionally, the top of the spring is provided with a low-resistance plate located at the bottom of the stop section, the low-resistance plate is provided with a guide post passing through the spring, and the receiving seat is provided with a guide hole for receiving the guide post.

[0024] By adopting the above technical solution, since the top of the spring is provided with a low-resistance plate located at the bottom of the stop section, on the one hand, the spring contacts the stop section through the low-resistance plate to reduce the friction between the spring and the stop section, thereby ensuring the smooth movement of the stop component towards the outside of the receiving seat. On the other hand, it makes the force on the top end of the spring more balanced, so as to avoid the phenomenon of the spring detaching from the side of the passage, thereby increasing the stability of the spring. In addition, the low-resistance plate is provided with a guide post, and the receiving seat is provided with a guide hole for accommodating the guide post. When the spring moves downward under the pressure of the stop section, the guide post and the guide hole slide relative to each other. On the one hand, the guide post can guide the deformation direction of the spring to increase the stability of the spring when it deforms, thereby ensuring the elastic support effect on the stop section. On the other hand, it can also increase the connection stability between the spring and the receiving seat.

[0025] Optionally, the connecting seat includes a seat body and an annular body disposed inside the bottom end of the seat body, the arcuate groove is disposed in the annular body, and the receiving seat has an edge capable of engaging with the top stop of the seat body.

[0026] By adopting the above technical solution, since the arc groove is located on the ring body, the stop member can slide within a relatively large range, thereby further shortening the distance that the silicon steel sheet to be placed in the accommodating space needs to move, and further ensuring the production quality of the stator and rotor; and the accommodating seat has an edge that can cooperate with the stop on the top of the seat body, thereby enabling the connecting seat to support the accommodating seat and increase the stability of the accommodating seat.

[0027] Optionally, the drive structure includes an external gear ring disposed at the bottom of the accommodating seat, a drive gear meshing and drivingly connected with the external gear ring, and a drive member for driving the drive gear to rotate.

[0028] By adopting the above technical solution, when driving the accommodating seat, the driving component is activated, which drives the drive gear, thereby causing the drive gear to drive the external gear ring to rotate, and the external gear ring to drive the accommodating seat to rotate, so as to realize the rotation of the accommodating seat.

[0029] Optionally, the drive structure further includes a mounting base, the drive gear is disposed inside the mounting base, and the drive gear has a transmission shaft passing through the mounting base.

[0030] By adopting the above technical solution, since the driving gear is located inside the mounting base and has a transmission shaft passing through the mounting base, the stability of the driving gear is increased, the assembly difficulty of the driving gear is reduced, and the transmission efficiency between the driving gear and the external gear ring is guaranteed.

[0031] Due to the adoption of the above technical solution, the beneficial effects achieved by this application are as follows:

[0032] 1. The stacking mold in this application includes a connecting seat, a receiving seat, a stop member, and a driving structure. The connecting seat has a central hole, and the receiving seat has a through hole that passes through it along its own axial direction. The inside of the through hole forms a receiving space for receiving silicon steel sheets, and the receiving seat passes through the central hole. The stop member is connected to the connecting seat, and one end of the connecting seat extends into the receiving space. The driving structure is used to drive the receiving seat to rotate. When the receiving seat and the connecting seat rotate relative to each other, the stop member moves towards the outside of the receiving seat, thereby realizing that the receiving seat and the connecting seat rotate relative to each other by a certain angle. At this time, the silicon steel sheets that are in contact with the wall of the through hole slide relative to the wall of the through hole under the action of the rotation of the receiving seat, so that the two adjacent silicon steel sheets are completely attached, and the influence of uneven workpiece thickness caused by the stamping of silicon steel sheets on the overall thickness of the stator and rotor is avoided, thereby ensuring the uniformity of the thickness of the stator and rotor, and thus ensuring the production quality of the stator and rotor.

[0033] 2. The stop member in this application has a connecting section and a stop section. The stop section passes through the receiving seat. The connecting seat has an arc-shaped groove extending along its circumference. The distance between the arc-shaped groove and the wall of the through hole gradually increases along the circumference of the connecting seat. The connecting section passes through the arc-shaped groove, so that when the receiving seat and the connecting seat rotate relative to each other, the stop member can rotate with the receiving seat under the action of the stop section. This causes the connecting section of the stop member to slide relative to the arc-shaped groove, so that the stop member moves towards the outside of the receiving seat under the relative rotation of the receiving seat and the connecting seat. This achieves that as the number of silicon steel sheets stacked together increases, the stop-stopping area between the stop section and the silicon steel sheets decreases. Finally, after the required number of silicon steel sheets are stacked, the stop section releases its stop-stopping engagement with the silicon steel sheets, so that the stacked silicon steel sheets fall through the bottom opening of the through hole. In addition, the groove wall of the arc-shaped groove can also limit the stop member to prevent the stop member from rotating under the gravity of the silicon steel sheet, thereby increasing the support stability of the stop member on the silicon steel sheet.

[0034] 3. In this application, the arc-shaped groove passes through the connecting seat axially. The receiving seat is provided with a through-hole, and the stop section passes through the through-hole. The receiving seat is provided with an elastic element acting on the stop section. The elastic element can apply an upward elastic force to the stop section, thereby enabling the stop section to move elastically in the axial direction of the receiving seat according to the change in the number of silicon steel sheets. On the one hand, this reduces the distance that the silicon steel sheets need to move when placed in the receiving space, thereby reducing the possibility that the silicon steel sheets may contact the hole wall of the through hole and become offset, thus further ensuring the uniformity of the stator and rotor thickness. On the other hand, it enables the stop section to move downward elastically as the number of silicon steel sheets placed above the stop section gradually increases, so as to ensure that the required number of silicon steel sheets can be placed in the receiving space, thereby ensuring the production quality of the stator and rotor.

[0043] To more clearly illustrate the overall concept of this application, a detailed explanation is provided below with reference to the accompanying drawings.

[0044] Many specific details are set forth in the following description in order to provide a full understanding of this application.

[0048] Reference Figures 1 to 5 A stacking mold for stator and rotor production is disclosed, comprising a connecting seat 1, a receiving seat 2, a stop member 3, and a driving structure 4. The connecting seat 1 has a central hole; the receiving seat 2 has a through hole that passes through it along its own axial direction, forming a receiving space for accommodating silicon steel sheets inside the through hole, and the receiving seat 2 is disposed through the central hole; the stop member 3 is connected to the connecting seat 1, and one end of the connecting seat 1 extends into the receiving space; the driving structure 4 is used to drive the receiving seat 2 to rotate, and when the receiving seat 2 rotates relative to the connecting seat 1, the stop member 3 moves toward the outside of the receiving seat 2.

[0049] When using the stacking mold of this application, the robot places silicon steel sheets in the accommodating space so that the stop member 3 blocks the silicon steel sheet located at the bottom layer, so that the silicon steel sheet stays stably in the accommodating space, and multiple silicon steel sheets are stacked in the accommodating space. When a certain number of silicon steel sheets are stacked or after one silicon steel sheet is placed in the accommodating space, the drive structure 4 drives the accommodating seat 2, which in turn causes the accommodating seat 2 to rotate relative to the connecting seat 1 at a certain angle. At this time, the silicon steel sheet that is in contact with the wall of the through hole slides relative to the wall of the through hole under the rotation of the accommodating seat 2, so that two adjacent silicon steel sheets are completely attached, and the uneven thickness of the workpiece caused by the stamping of the silicon steel sheet is avoided from affecting the overall thickness of the stator and rotor, thereby ensuring the uniformity of the thickness of the stator and rotor, and thus ensuring the production quality of the stator and rotor.

[0050] In addition, when the receiving seat 2 and the connecting seat 1 rotate relative to each other, the stop member 3 moves outward of the receiving seat 2 under the action of the connecting seat 1 and the receiving seat 2, so that after the silicon steel sheets are stacked to the required number, the stop member 3 moves to the outside of the silicon steel sheets, so that the stop member 3 and the bottom of the silicon steel sheets form a clearance, thereby allowing the stacked silicon steel sheets to fall through the bottom opening of the through hole, so as to release the stacked silicon steel sheets, so that the workers can carry out the next step of processing on the stacked silicon steel sheets, thereby greatly improving the production efficiency of the stator and rotor.

[0051] It should be noted that after a stator or rotor is stacked, the drive structure 4 needs to drive the receiving seat 2 to rotate in the opposite direction so that the stop member 3 can be reset.

[0052] This application does not specify the number of stop members 3; preferably, refer to... Figure 3 The stop members 3 are evenly spaced in six places along the circumference of the receiving seat 2 to increase the number of stop points for the silicon steel sheet, thereby increasing the stability of the silicon steel sheet. In other embodiments, the stop members 3 may also be provided in other quantities such as three, four, five, etc.

[0053] This application does not specifically limit the manner in which the stop member 3 moves outward from the receiving seat 2 when the receiving seat 2 and the connecting seat 1 rotate relative to each other. Preferably, refer to Figure 2 , Figure 4 and Figure 5 The stop member 3 has a connecting section 31 and a stop section 32. The stop section 32 passes through the receiving seat 2. The connecting seat 1 has an arc-shaped groove 121 extending along its circumference. The distance between the arc-shaped groove 121 and the wall of the central hole gradually increases along the circumference of the connecting seat 1. The connecting section 31 passes through the arc-shaped groove 121.

[0054] As the distance between the arc groove 121 and the wall of the central hole gradually increases along the circumference of the connecting seat 1, and the connecting section 31 passes through the arc groove 121, when the receiving seat 2 and the connecting seat 1 rotate relative to each other, the stop member 3 can rotate with the receiving seat 2 under the action of the stop section 32, so that the connecting section 31 of the stop member 3 slides relative to the arc groove 121, so that the stop member 3 moves towards the outside of the receiving seat 2 under the relative rotation of the receiving seat 2 and the connecting seat 1, so that as the number of silicon steel sheets stacked together increases, the stop cooperation area between the stop section 32 and the silicon steel sheets decreases, and finally, after the required number of silicon steel sheets are stacked, the stop section 32 releases its stop cooperation with the silicon steel sheets, so that the stacked silicon steel sheets fall through the bottom opening of the through hole. In addition, the groove wall of the arc groove 121 can also limit the stop member 3 to prevent the stop member 3 from rotating under the gravity of the silicon steel sheet, thereby increasing the support stability of the stop member 3 on the silicon steel sheet.

[0055] The better one is to refer to Figure 2 , Figure 4 and Figure 5 The stop section 32 is set perpendicular to the connecting section 31, thereby making the stop member 3 L-shaped to increase the stopping effect on the silicon steel sheet.

[0056] If the distance between the arc-shaped groove 121 and the wall of the central hole gradually increases in the clockwise direction, then when the receiving seat 2 rotates clockwise under the action of the driving structure 4, the stop member 3 moves towards the outside of the receiving seat 2 under the action of the receiving seat 2 and the connecting seat 1; if the distance between the arc-shaped groove 121 and the wall of the central hole gradually increases in the counterclockwise direction, then when the receiving seat 2 rotates counterclockwise under the action of the driving structure 4, the stop member 3 moves towards the outside of the receiving seat 2 under the action of the receiving seat 2 and the connecting seat 1.

[0057] Furthermore, refer to Figure 2 , Figure 4 and Figure 5 The arc-shaped groove 121 passes through the connecting seat 1 in the axial direction. The receiving seat 2 is provided with a through port 21. The stop section 32 passes through the through port 21. The receiving seat 2 is provided with an elastic member 23 that acts on the stop section 32. The elastic member 23 can apply an upward elastic force to the stop section 32.

[0058] Because the arc-shaped groove 121 passes through the connecting seat 1 in the axial direction, and the receiving seat 2 is provided with a through port 21, the stop section 32 passes through the through port 21, and the receiving seat 2 is provided with an elastic element 23 acting on the stop section 32, the stop section 32 can move elastically in the axial direction of the receiving seat 2 according to the change in the number of silicon steel sheets. On the one hand, this reduces the distance that the silicon steel sheets need to move when they are placed in the receiving space, so as to reduce the phenomenon that the silicon steel sheets may come into contact with the hole wall of the through hole and become offset, thereby further ensuring the uniformity of the thickness of the stator and rotor. On the other hand, as the number of silicon steel sheets placed above the stop section 32 gradually increases, the stop section 32 moves downward elastically to ensure that the required number of silicon steel sheets can be placed in the receiving space, so as to ensure the production quality of the stator and rotor.

[0059] This application does not specifically limit the structure of the elastic element 23, which can adopt any of the following embodiments:

[0060] Example 1, in this example, refers to Figure 2 The elastic element 23 is a spring sleeved on the outside of the receiving seat 2. The receiving seat 2 has a support part 24, which is located at the bottom of the spring to support the spring.

[0061] Since the support portion 24 is located at the bottom of the spring, it can support the spring, thereby increasing the elastic support effect of the spring on the stop section 32. Furthermore, the spring is sleeved outside the receiving seat 2, allowing it to avoid interfering with the falling of the silicon steel sheet within the receiving space, thus ensuring the stacking efficiency of the silicon steel sheet. Additionally, because the spring is sleeved outside the receiving seat 2, the receiving seat 2 can also guide the deformation of the spring, increasing its stability during deformation.

[0062] This application does not specifically limit the structure of the support portion 24. Preferably, the support portion 24 is a ring structure extending circumferentially along the receiving seat 2 to increase the number of support points for the spring, thereby increasing the stability of the spring. In other embodiments, the support portion 24 may also be a block structure spaced circumferentially along the receiving seat 2.

[0063] Example 2, in this example, refer to Figure 4 and Figure 5 The elastic element 23 is a spring provided in the passage 21, with one bottom end of the spring contacting the wall of the passage 21 and one top end of the spring contacting the bottom of the stop section 32.

[0064] Since the elastic element 23 is a spring located in the passage 21, the elastic element 23 can avoid the phenomenon that the gap between the receiving seat 2 and the connecting seat 1 is required due to the spring being located outside the receiving seat 2. This reduces the assembly difficulty of the receiving seat 2 and improves the assembly efficiency of the stacking mold.

[0065] In this embodiment, the method of installing the spring is not specifically limited, and it can be any of the following implementation examples:

[0066] Implementation Example 1, in this implementation example, refer to Figure 4 A positioning post 211 is provided through the wall of the opening 21, and a spring is sleeved on the positioning post 211.

[0067] Specifically, the positioning post 211 is located on the bottom wall of the through-hole 21, and one bottom end of the spring is sleeved on the outside of the positioning post 211, and the inner circumferential surface of the bottom end of the spring is interference-fitted with the positioning post 211.

[0068] Since the spring is sleeved on the positioning post 211, the positioning post 211 can position the spring to avoid the spring from separating from the positioning post 211. This increases the connection stability between the spring and the through port 21, while reducing the difficulty of installing the spring, thereby further improving the assembly efficiency of the stacked mold.

[0069] Implementation Example 2, in this implementation example, refer to Figure 5 The top of the spring is provided with a low-resistance plate 212 located at the bottom of the stop section 32. The low-resistance plate 212 is provided with a guide post 213 passing through the spring. The receiving seat 2 is provided with a guide hole 214 for receiving the guide post 213.

[0070] Because the top of the spring is provided with a low-resistance plate 212 located at the bottom of the stop section 32, on the one hand, the spring contacts the stop section 32 through the low-resistance plate 212 to reduce the friction between the spring and the stop section 32, so as to ensure the smooth movement of the stop member 3 toward the outside of the receiving seat 2. On the other hand, it makes the force on the top end of the spring more balanced, so as to prevent the spring from detaching from the side of the passage 21, thereby increasing the stability of the spring. Furthermore, the low-resistance plate 212 is provided with a guide post 213, and the receiving seat 2 is provided with a guide hole 214 for accommodating the guide post 213. As a result, when the spring moves downward under the pressure of the stop section 32, the guide post 213 and the guide hole 214 slide relative to each other. On the one hand, the guide post 213 can guide the deformation direction of the spring to increase the stability of the spring when it deforms, thereby ensuring the elastic support effect on the stop section 32. On the other hand, it can also increase the connection stability between the spring and the receiving seat 2.

[0071] This application does not specify the connection method between the guide post 213 and the low-resistivity plate 212. Preferably, refer to... Figure 5 The guide post 213 is fixedly connected to the low-resistivity plate 212 to increase the connection stability between the guide post 213 and the low-resistivity plate 212. In other embodiments, the guide post 213 can also be threadedly connected to the low-resistivity plate 212.

[0072] In other embodiments, the elastic element 23 may also be an elastic sheet or other elastic structures.

[0073] In other embodiments, the wall of the central hole is divided into multiple segments along its circumference, and the distance between each segment of the hole wall and the center point of the connecting seat 1 gradually increases along the circumference of the connecting seat 1. The receiving seat 2 is provided with a reset member that acts on the stop member 3. The reset member is used to apply an elastic force to the stop member 3 in the direction of the outside of the receiving seat 2, so that when the receiving seat 2 and the connecting seat 1 rotate relative to each other, the stop member 3 moves in the direction of the outside of the receiving seat 2 under the action of the reset member and the wall of the central hole.

[0074] In a preferred embodiment, refer to Figure 2 , Figure 4 and Figure 5 The connecting seat 1 includes a seat body 11 and an annular body 12 disposed inside the bottom end of the seat body 11. An arc-shaped groove 121 is disposed in the annular body 12. The receiving seat 2 has an edge 22 that can cooperate with the top stop of the seat body 11.

[0075] Since the arc groove 121 is provided on the ring body 12, the stop member 3 can slide within a relatively large range, thereby further shortening the distance that the silicon steel sheet to be placed in the accommodating space needs to move, so as to further ensure the production quality of the stator and rotor; and the accommodating seat 2 has an edge 22 that can cooperate with the top stop of the seat body 11, thereby enabling the connecting seat 1 to support the accommodating seat 2, thereby increasing the stability of the accommodating seat 2.

Figure 1 and Figure 2 The drive structure 4 includes an external gear ring 41 located at the bottom of the housing 2, a drive gear 42 meshing and driving the drive gear 42, and a drive component for driving the drive gear 42 to rotate.

[0077] When the accommodating seat 2 is driven, the driving component is activated, which drives the drive gear 42, thereby causing the drive gear 42 to drive the external gear ring 41 to rotate, and the external gear ring 41 to drive the accommodating seat 2 to rotate, so as to drive the accommodating seat 2 to rotate.

[0078] This application does not impose specific limitations on the structure of the driving component. Preferably, the driving component is a servo motor to achieve precise control of the rotation angle of the accommodating seat 2. In other embodiments, the driving component can also be a pneumatic motor or other structures capable of driving the drive gear 42 to rotate.

[0079] Furthermore, refer to Figure 1 and Figure 2 The drive structure 4 also includes a mounting base 43, with the drive gear 42 located inside the mounting base 43. The drive gear 42 has a transmission shaft 421 passing through the mounting base 43, which increases the stability of the drive gear 42, reduces the assembly difficulty of the drive gear 42, and ensures the transmission efficiency between the drive gear 42 and the external gear ring 41.

[0080] This application does not impose specific limitations on the transmission connection method between the servo motor and the drive gear 42. Preferably, the output shaft of the servo motor is provided with a gear that meshes and transmits power to the drive gear 42, thereby realizing the transmission connection between the servo motor and the drive gear 42 and reducing the height of the drive structure 4. In other embodiments, the output shaft of the servo motor and the rotating shaft are connected by a coupling.

[0081] In other embodiments, the drive structure 4 includes a hollow rotating platform and a drive component. The output end of the hollow rotating platform is coaxially and fixedly connected to the accommodating seat 2, and the drive component is drivenly connected to the input end of the hollow rotating platform.
