Description

Technical Field

[0001] This invention relates to the field of stator processing equipment technology, and specifically to a turntable mechanism. Background Technology

[0002] An electric motor is an electromagnetic device that converts electrical energy into mechanical energy based on the law of electromagnetic induction. It generally consists of two main parts: a stator and a rotor. The stator is the stationary part, usually composed of a stator core and stator windings, while the rotor is the rotating part, usually composed of a rotor core and rotor windings.

[0003] During stator production and assembly, the stator windings need to be assembled into the stator core, which requires several winding and expansion processes. The traditional processing method is to perform several winding and expansion processes on a single stator core each time. After completion, the stator is placed in a specific area or transported to the next process, and then a new stator core is assembled and processed. This individual processing results in low production efficiency and high labor costs. Summary of the Invention

[0004] To address the technical problems of low production efficiency and high labor costs in stator processing in the prior art, this invention proposes a turntable mechanism that can drive multiple working components to rotate to different workstations for operation. This mechanism offers a high degree of automation, and each working component can be raised and lowered independently, reducing waiting time at each workstation and improving work and production efficiency.

[0005] The technical solution of the present invention:

[0006] A turntable mechanism, comprising:

[0007] Multiple working components are arranged at intervals along the circumferential direction, and the multiple working components can be driven to rotate together horizontally around the center of their respective circumference;

[0008] Each of the aforementioned working components is configured to be raised and lowered independently.

[0009] Furthermore, the turntable mechanism includes three working components evenly spaced apart; each working component rotates sequentially between the loading / unloading station, the winding station, and the expansion station. The loading / unloading station is used to load the stator core, the winding station is used to wind the stator core several times, the expansion station is used to expand the stator core after several windings, and the loading / unloading station is also used to unload the stator core after winding and expansion.

[0010] Furthermore, the turntable mechanism includes a rotating module and a base. The rotating module drives the base to rotate. The base is provided with multiple lifting modules and lifting slide rails corresponding to multiple working components. Each working component includes a support seat. The support seat can be lifted and lowered by the lifting module. The support seat is provided with a lifting slider that cooperates with the lifting slide rail.

[0011] Furthermore, the working component also includes a tooth protection module disposed on the support base. The tooth protection module includes an upper tooth protection module and a lower tooth protection module. The upper tooth protection module includes an upper tooth protection seat and a plurality of upper tooth protection teeth arranged circumferentially in the upper tooth protection seat. The lower tooth protection module includes a lower tooth protection seat and a plurality of lower tooth protection teeth arranged circumferentially in the lower tooth protection seat. The upper tooth protection seat and the lower tooth protection seat have an upper through hole and a lower through hole respectively formed in their centers. The upper tooth protection seat is also provided with a lifting seat around the upper through hole. The lifting seat protrudes inward. When feeding, the stator core passes through the lower through hole and is lifted by the lifting seat. After being lifted into place, the upper tooth protection and the lower tooth protection are respectively extended radially inward. A guide rod is also connected between the upper tooth protection seat and the lower tooth protection seat. A radial pressure block for pressing the stator core is also formed on the lower tooth protection. A protective sleeve that mates with the outer periphery of the stator core is also provided on the lower tooth protection seat.

[0012] Furthermore, the upper tooth holder is provided with an upper tooth disc, on which multiple upper arc-shaped grooves are formed. The upper tooth is provided with an upper connecting rod corresponding to each of the upper arc-shaped grooves. The upper tooth is correspondingly disposed in an upper sliding groove of the upper tooth holder. Teeth are formed on the outer periphery of the upper tooth disc, allowing it to be driven to rotate. When the upper tooth disc rotates, the upper tooth extends radially into or out of the corresponding upper sliding groove. The lower tooth holder is provided with a lower tooth disc, on which multiple lower arc-shaped grooves are formed. The lower tooth is provided with a lower connecting rod corresponding to each of the lower arc-shaped grooves. The lower tooth is correspondingly disposed in a lower sliding groove of the lower tooth holder. Teeth are formed on the outer periphery of the lower tooth disc, allowing it to be driven to rotate. When the lower tooth disc rotates, the lower tooth extends radially into or out of the corresponding lower sliding groove.

[0013] Furthermore, the lower tooth guard seat is provided with a first gear that meshes with the lower tooth guard disc, and the upper tooth guard seat is provided with a second gear that meshes with the upper tooth guard disc. The first gear and the second gear rotate coaxially, and when the lower tooth guard disc is driven to rotate, the first gear and the second gear can drive the upper tooth guard disc to rotate synchronously.

[0014] Furthermore, the working component also includes an indexing plate, on which the tooth protection module is disposed, and the outer periphery of the indexing plate is toothed and can be driven to rotate.

[0015] Furthermore, during the rotation of the working component after one expansion and before the next winding, the indexing plate is driven to rotate; the working component also includes a positioning component disposed on the support, the positioning component being used to position the indexing plate when it is not rotating.

[0016] Furthermore, the working component also includes a drive module, which includes a rotary drive module and a linear drive module. The output end of the rotary drive module is provided with a drive gear. The linear drive module can drive the rotary drive module to rise and fall so that the drive gear can mesh with the lower gear plate or with the indexing plate respectively.

[0017] Furthermore, the linear drive module includes a first cylinder and a second cylinder. The first cylinder is used to drive the drive gear to switch between the middle position of the lower gear guard and the indexing plate and the circumferential outer position of the lower gear guard. The second cylinder is used to drive the drive gear to switch between the middle position of the lower gear guard and the indexing plate and the circumferential outer position of the indexing plate.

[0018] By adopting the above technical solution, the turntable mechanism provided by the present invention has the following beneficial effects compared with the prior art: The turntable mechanism provided by the present invention can simultaneously process multiple stator cores, improving work efficiency, saving manpower, and achieving a high degree of automation. Furthermore, by setting each working component to be independently raised and lowered, the present invention allows each working component to independently raise and lower itself while performing its corresponding processing operation at each workstation, completing its own processing operation independently. Compared with overall raising and lowering, this is more convenient and significantly reduces waiting time, further improving work and production efficiency. Attached Figure Description

[0031] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the present invention or its application or use. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0032] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0033] For ease of description, spatial relative terms such as "above," "on top of," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation beyond the orientation of the device as described in the figures. For example, if the device in the figures were inverted, a device described as "above" or "on top of" other devices or structures would subsequently be positioned as "below" or "under" other devices or structures. Thus, the exemplary term "above" can include both "above" and "below." The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used herein will be interpreted accordingly.

[0034] Furthermore, it should be noted that the use of terms such as "first" and "second" to define components is merely for the purpose of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore should not be construed as limiting the scope of protection of this invention.

[0035] like Figure 1-4 As shown, this embodiment provides a turntable mechanism for stator manufacturing. The turntable mechanism includes multiple working components 100. Each working component 100 is used for receiving, loading, positioning, indexing, and unloading the stator core 200. The number of components can be set as needed, for example, two or more. These working components 100 are spaced apart along the circumference, preferably evenly spaced, and can be driven to rotate together horizontally around the center of their respective circumference. Each working component 100 can also be individually driven to perform lifting movements.

[0036] Specifically, the turntable mechanism includes a rotating module 300 and a base 500. The rotating module 300 can drive the base 500 to rotate around the rotating axis 400. On the base 500, multiple working components 100 are respectively provided with lifting modules (not shown in the figure) and lifting slide rails 600 in multiple directions. Each working component 100 includes a bearing seat 1. The lifting module can be, but is not limited to, a screw and nut structure. Each lifting module can be connected to the top of a bearing seat 1 to drive it to perform lifting and lowering movements. Each bearing seat 1 is also provided with a lifting slider 11 that corresponds to and cooperates with the lifting slide rail 600, which plays a guiding role during lifting and lowering movements.

[0037] Preferably, the turntable mechanism includes three working components 100, which are arranged circumferentially at 120-degree intervals. Each working component 100 rotates sequentially between the loading / unloading station, the winding station, and the expansion station. The loading / unloading station is used to load the stator core 200; the winding station is used to wind the stator core 200 several times; the expansion station is used to expand the stator core 200 after several windings; and the loading / unloading station is also used to unload the stator core 200 after winding and expansion. During operation, one working component 100 loads the stator core 200 at the loading / unloading station, receives the stator core 200, and positions and fixes it. Then, this working component 100 rotates sequentially to the winding station and the expansion station to perform several windings and expansions before rotating back to the loading / unloading station to unload the stator core.

[0038] This embodiment utilizes the turntable mechanism to simultaneously process multiple stator cores 200, improving work efficiency, saving manpower, and achieving a high degree of automation. Most importantly, this embodiment allows each working component 100 to be raised and lowered independently. This enables each component to perform its respective processing operation at each workstation independently, such as raising and lowering it individually for loading and unloading at the loading / unloading station, or raising and lowering it individually for winding at the winding station. Compared to overall lifting, this makes working at each workstation more convenient and significantly reduces waiting time, further improving work and production efficiency.

[0039] Since the working component 100 needs to be rotated to different work stations for processing, each working component 100 needs to perform operations such as feeding, several winding and expansion, and unloading. Therefore, each working component 100 also needs to have the function of receiving the stator core 200, positioning it, and indexing and rotating it.

[0040] In this regard, such as Figure 3-9 As shown, the working component 100 of this embodiment also includes a tooth protection module 2 disposed on the support seat 1. The tooth protection module 2 includes an upper tooth protection module 21 and a lower tooth protection module 22 coaxially disposed. The upper tooth protection module 21 includes an annular upper tooth protection seat 211 and a plurality of upper teeth 212 that are circumferentially evenly arranged and radially slidably disposed in the upper tooth protection seat 211. The plurality of upper teeth 212 can be radially slid in and out. The lower tooth protection module 22 includes an annular lower tooth protection seat 221 and a plurality of lower teeth 222 that are circumferentially evenly arranged and radially slidably disposed in the lower tooth protection seat 221. The plurality of lower teeth 222 can also be radially slid in and out.

[0041] The upper tooth holder 211 and the lower tooth holder 221 have upper through holes 213 and lower through holes 223 respectively formed in their centers. The support base 1 includes a vertical plate, a bottom plate, and two side plates. The bottom plate of the support base 1 also has a through hole 12 for the stator core 200 to pass through. The upper tooth holder 211 also has a lifting seat 215 around the upper through hole 213. The lifting seat 215 protrudes inward from the upper through hole 213, so that when feeding, the stator core 200 passes through the through hole 12 of the support base 1 and the lower through hole 223 of the lower tooth holder 221 in sequence from bottom to top, and then the upper tooth module 21 is lifted by the lifting seat 215. After being lifted into place, the upper tooth 212 and the lower tooth 222 extend radially inward, thereby receiving the fed stator core 200 and positioning and fixing it. It should be noted that the tooth in the figure is in the extended state.

[0042] Guide rods 225 are connected to the upper tooth protection module 21 and the lower tooth protection module 22. When the upper tooth protection module 21 moves up and down, it is guided by the guide rods 225. Because the upper tooth protection module 21 can move, this structure can adapt to stator cores 200 of various lengths. Furthermore, preferably, in this embodiment, a radial pressure block 2222 is formed on the lower tooth protection module 222 to press and fix the stator core 200, and the lower tooth protection seat 221 is also provided with a sleeve 226 that can cooperate with the outer periphery of the stator core 200, thereby better assisting in the positioning of the stator core 200. In the initial state, a certain gap is left between the upper tooth protection module 21 and the lower tooth protection module 22. The lower tooth protection module 22 is supported by a support column 227, and shock-absorbing components can also be provided on the support column 227.

[0043] Regarding the sliding structure of the upper guard tooth 212 and the lower guard tooth 222, specifically, as follows: Figure 6-7 As shown, in this embodiment, an annular upper tooth plate 214 is provided in the upper tooth plate 211. Multiple upper arc-shaped grooves 2141 are evenly arranged in the upper tooth plate 214. The upper tooth 212 is provided with an upper connecting rod 2121 that corresponds to and cooperates with the upper arc-shaped groove 2141. The upper tooth 212 is correspondingly arranged in the upper sliding groove 2111 arranged radially in the upper tooth plate 211. The outer periphery of the upper tooth plate 214 has teeth that can be driven to rotate. When the upper tooth plate 214 rotates, each upper arc-shaped groove 2141 causes the upper connecting rod 2121 located therein to be subjected to force and move. The upper tooth 212 is limited in the upper sliding groove 2111, so that the upper tooth 212 can only slide radially into or out along the corresponding upper sliding groove 2111.

[0044] Similarly, as Figure 8-9As shown, the lower tooth holder 221 is provided with an annular lower tooth disc 224. Multiple lower arc-shaped grooves 2241 are evenly arranged in the lower tooth disc 224. The lower tooth 222 is provided with a lower connecting rod 2221 that corresponds to and cooperates with the lower arc-shaped groove 2241. The lower tooth 222 is correspondingly set in the radially arranged sliding groove 2211 in the lower tooth holder 221. The outer periphery of the lower tooth disc 224 has teeth that can be driven to rotate. When the lower tooth disc 224 rotates, each lower arc-shaped groove 2241 causes the lower connecting rod 2221 located therein to be subjected to force and move. The lower tooth 222 is then limited in the sliding groove 2211, so that the lower tooth 222 can only slide radially into or out along the corresponding sliding groove 2211.

[0045] Preferably, such as Figure 5 In this embodiment, a first gear 2281 is provided on the lower gear holder 221, located radially outward of the lower gear disc 224, meshing with the lower gear disc 224. A second gear 2282 is provided on the upper gear holder 211, located radially outward of the upper gear disc 214, meshing with the upper gear disc 214. The first gear 2281 and the second gear 2282 rotate coaxially. For example, when the first gear 2281 rotates, it drives the second gear 2282 to rotate synchronously via the key shaft 2283. Thus, when the lower gear disc 224 is driven to rotate, the first gear 2281 and the second gear 2282 can drive the upper gear disc 214 to rotate synchronously. In other words, in this embodiment, only the lower tooth guard plate 224 needs to be driven to achieve synchronous rotation of the lower tooth guard plate 224 and the upper tooth guard plate 214, thereby ensuring that the upper tooth guard 212 and the lower tooth guard 222 extend in and out at the same time. Furthermore, the key shaft 2283 connecting the first gear 2281 and the second gear 2282 can also serve as one of the guide rods 225 when the upper tooth guard seat 211 is raised or lowered.

[0046] Furthermore, the working component 100 of this embodiment also includes an indexing plate 3, which is disposed between the bearing seat 1 and the tooth protection module 2. That is, the tooth protection module 2 is disposed on the indexing plate 3, and teeth are formed on the outer periphery of the indexing plate 3 so that it can be driven to rotate. When the indexing plate 3 rotates, it can drive the tooth protection module 2 on it to rotate together, which facilitates the next winding operation. The indexing plate 3 and the tooth protection module 2 are coaxially disposed. Preferably, a ring of rollers can also be provided at the bottom of the indexing plate 3 to facilitate its rotation. In this embodiment, after each working component 100 receives the stator core 200, it needs to move to the winding station for the first winding, then to the expansion station for the first expansion, and then to the winding station and expansion station for the second winding and expansion respectively. Then it needs to move to the winding station and expansion station again for the third winding and expansion respectively. In this way, the indexing plate 3 can be driven to rotate during the rotation of the working component 100 after one expansion and before the next winding, so that the indexing rotation can be achieved in this time, thereby saving the time of the working component 100 working at the winding station and improving work efficiency.

[0047] Furthermore, the working component 100 also includes a positioning component 4 disposed on the support 1, which is used to position the indexing plate 3 when it is not rotating. Specifically, as Figure 4 The positioning component 4 includes an extendable positioning tooth 41. An arc-shaped plate 42 is connected to the lower tooth holder 221. The radial outer end of the arc-shaped plate 42 is provided with corresponding teeth. After the indexing plate 3 is rotated into position, the positioning tooth 41 extends out and clamps the arc-shaped plate 42 for positioning.

[0048] In this embodiment, the indexing plate 3 and the lower gear guard plate 224 are driven to rotate by the drive module 5. The drive module 5 includes a rotation drive module 51 and a linear drive module 52. The rotation drive module 51 is a motor, and its output end is provided with a drive gear 53. The drive gear 53 indirectly drives the indexing plate 3 or the lower gear guard plate 224 to rotate through the intermediate gear 54. The linear drive module 52 can drive the rotation drive module 51 to rise and fall so that the drive gear 53 meshes with the lower gear guard plate 224 or with the indexing plate 3 respectively.

[0049] Preferably, the linear drive module 52 in this embodiment adopts a dual-cylinder structure, specifically, as shown in the example below. Figure 3-4It includes a first cylinder 521 and a second cylinder 522. The first cylinder 521 is used to drive the drive gear 53 to switch between the middle position of the lower gear guard plate 224 and the indexing plate 3 and the circumferential outer position of the lower gear guard plate 224. The second cylinder 522 is used to drive the drive gear 53 to switch between the middle position of the lower gear guard plate 224 and the indexing plate 3 and the circumferential outer position of the indexing plate 3. In other words, there is a certain gap between the indexing plate 3 and the lower gear guard plate 224. When neither the lower gear guard plate 224 nor the indexing plate 3 needs to rotate, the drive gear 53 and the intermediate gear 54 can remain at this gap height. When the lower gear guard plate 224 needs to rotate, the first cylinder 521 moves, causing the drive gear 53 and the intermediate gear 54 to move upward to the outer circumference of the lower gear guard plate 224, driving it to rotate. After rotation, they return to their original positions. When the indexing plate 3 needs to rotate, the second cylinder 522 moves, causing the drive gear 53 and the intermediate gear 54 to move downward to the outer circumference of the indexing plate 3, driving it to rotate. After rotation, they return to their original positions. Thus, this embodiment, by cleverly setting a dual-cylinder structure for switching drives, can greatly save costs.

[0050] As can be seen from the above, the turntable mechanism provided in this embodiment can drive multiple working components to rotate to different work stations for work, and each working component can be raised and lowered independently, reducing the waiting time when working at each work station and improving work and production efficiency.

[0051] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
