Description
Technical Field
[0001] This utility model relates to the field of motor coil assembly technology, and in particular to an integrated coil coarse and fine coil assembly mechanism. Background Technology
[0002] Stator windings refer to the windings installed on the stator. These windings are assembled from multiple stators into a single unit, requiring rounding and welding. Therefore, during rounding, individual stator core pieces are placed into a rounding device for assembly. In traditional motor stator core rounding processes, a step-by-step approach of coarse and fine rounding is commonly used. First, the dispersed iron core pieces are roughly gathered into a circle, then the semi-finished product is transferred to another station or a different fixture is used for extrusion and positioning. This step-by-step, transfer-based operation is not only cumbersome and inefficient, but the transfer process can also easily lead to core displacement or misalignment, affecting the final rounding accuracy and stability. Furthermore, the extrusion limiting structure of existing fine rounding devices is mostly a fixed design, making it difficult to quickly and accurately adapt to changes in the extrusion stroke required by different iron core thicknesses. This inconvenience in adjustment also affects the rounding accuracy and efficiency of products of different specifications. Utility Model Content
[0003] In view of this, the present invention provides an integrated coil coarse and fine coil assembly mechanism to solve the above-mentioned technical problems.
[0004] An integrated coil coarse and fine rounding mechanism includes a base, two first guide rails mounted on a base plate, four guide plates slidably mounted on the first guide rails, four first linear drive devices mounted on the base plate and driving the guide plates to slide, a fixing frame mounted on the base plate, and two rounding assemblies mounted on the guide plates. Each rounding assembly includes multiple mounting plates, multiple rotating members rotatably connecting adjacent mounting plates, a positioning shaft mounted on the rotating members, two guide shafts mounted on the mounting plates, and multiple fine rounding assemblies mounted on the mounting plates. Adjacent mounting plates are rotatably connected via the rotating members. When the first linear drive devices move the two guide plates, the two... The two ends of the rounding assembly are brought close together to change the original straight-line arrangement of the multiple mounting plates into an arc-shaped arrangement. The rounding assembly includes a second guide rail on the mounting plate, a fixed plate on the mounting plate, a push block slidably mounted on the second guide rail, a second linear drive device on the fixed plate, two limit blocks on the push block, and two adjusting bolts respectively adjustable on the limit blocks. The output end of the second linear drive device is connected to the push block. The push block is used to place the stator to be rounded. The limit blocks are respectively mounted on both sides of the push block and move with the push block. The adjusting bolts are adjustablely inserted into the push block. The fixed plate is located in the moving direction of the limit blocks.
[0005] Furthermore,
[0006] Furthermore, the two first guide rails extend in parallel directions and support the sliding of the guide plates. The four guide plates are slidably mounted on the two first guide rails in pairs. Each guide plate has a guide groove. One end of the guide groove is close to the first linear drive device, and the other end is away from the first linear drive device. The guide groove is inclined.
[0007] Furthermore, the two guide shafts are respectively disposed on the mounting plates located at both ends of the plurality of mounting plates and are respectively slidably disposed in the two guide grooves.
[0008] Furthermore, the output end of the first linear drive device is connected to the guide plate, and each guide plate is connected to one of the first linear drive devices.
[0009] Furthermore, the fixing frame is located at the center of the substrate and has a circular core, and a plurality of first positioning grooves are provided at intervals on the outer side wall of the circular core.
[0010] Furthermore, the width of the multiple mounting plates gradually decreases at one end facing the center of the circular core, and the outer contour shape of the mounting plate is an isosceles trapezoid.
[0011] Furthermore, the plurality of mounting plates are arc-shaped at one end facing the circular core and bent away from the circular core to form a second positioning groove.
[0012] Furthermore, the positioning shaft connects one of the rotating components located in the middle position among the plurality of rotating components to the fixed frame.
[0013] Furthermore, the fine-joining round assembly also includes a limiting shaft disposed on the push block. The limiting shaft is vertically disposed at the bottom of the push block. When multiple stators are coarsely joined together, the push block is located in the second positioning groove. When multiple stators are moved and pressed to perform fine-joining round assembly, the push block is located in the first positioning groove.
[0014] Compared with existing technologies, the integrated coil coarse and fine rounding mechanism provided by this utility model drives the guide plate to slide along the first guide rail through the first linear drive device, thereby moving the rounding assembly. This causes the guide shafts located at both ends of the rounding assembly to slide within the inclined guide grooves of the guide plate, forcing the multiple mounting plates of the two sets of rounding assemblies to change from a linear arrangement to an arc arrangement around the circular core of the fixed frame, completing the coarse rounding. Subsequently, the second linear drive device in the fine rounding assembly located on the mounting plate drives the push block to move along the second guide rail towards the center of the circular core, squeezing the stator to eliminate gaps. This achieves seamless connection and integrated completion of coarse and fine rounding in the same station, completely eliminating the need for transfer to the fine rounding station or fixture change after coarse rounding in traditional processes. This significantly simplifies the process flow, greatly improves rounding efficiency, and effectively avoids possible displacement or misalignment of the stator core during transfer, ensuring rounding accuracy and stability. Meanwhile, the adjusting bolt can conveniently and precisely adjust the extension length of the push block, thereby flexibly controlling the limit of the fine splicing extrusion stroke, enabling the mechanism to quickly and accurately adapt to the splicing requirements of stator cores of different thicknesses.

[0019] The specific embodiments of this utility model are described in further detail below. It should be understood that the description of the embodiments of this utility model herein is not intended to limit the scope of protection of this utility model.
[0020] like Figures 1 to 4 The diagram shows the structure of the integrated coil coarse and fine coil assembly mechanism provided by this utility model. The integrated coil coarse and fine coil assembly mechanism includes a base 10, two first guide rails 20 disposed on the base plate 10, four guide plates 30 slidably disposed on the first guide rails 20, four first linear drive devices 40 disposed on the base plate 10 and respectively driving the guide plates 30 to slide, a fixing frame 50 disposed on the base plate 10, and two coil assembly components 60 disposed on the guide plates 30. It is conceivable that the integrated coil coarse and fine coil assembly mechanism also includes other functional modules, such as electrical components, sensors, and mounting components, etc., which are technologies known to those skilled in the art and will not be described in detail here.
[0021] The base 10 is used to support the above-mentioned functional modules. Therefore, the base 10 is provided with a variety of functional structures, such as screws, bolts, clamps, etc., to complete the installation and assembly of the above-mentioned functional modules. It can be set according to actual needs, and will not be described in detail here.
[0022] The two first guide rails 20 extend in parallel directions and support the sliding of the guide plate 30. Four guide plates 30 are slidably disposed on two of the two first guide rails 20, thus each first guide rail 20 has a guide plate 30. Each guide plate 30 has a guide groove 31, one end of which is close to the first linear drive device 40, and the other end is away from the first linear drive device 40, causing the guide groove 31 to be inclined. Therefore, when the guide plate 30 drives the rounding assembly 60 to move, the rounding assembly 60 can slide along the guide groove 31 and move closer to each other to achieve rounding. A detailed explanation will follow below in conjunction with the rounding assembly 60.
[0023] The output end of the first linear drive device 40 is connected to the guide plate 30, thereby driving the guide plate 30 to slide along the first guide rail 20. Each guide plate 30 is connected to one of the first linear drive devices 40, so that the movement of each guide plate 30 can be controlled individually. The fixing frame 50 is located at the center of the base plate 10 and is provided with a circular core 51. A plurality of first positioning grooves 52 are provided at intervals on the outer side wall of the circular core 51.
[0024] The circular core 51 is used to ensure that the outer wall of the circular assembly 60 fits against the outer wall of the circular core 51 during the assembly of the circular assembly 60, serving as the inner core of the coil to determine the size of the inner circle and ensuring that the circular assembly 60 is assembled into a circle. The first positioning groove 52 is used for positioning during fine assembly, and a detailed explanation will be given below in conjunction with the circular assembly 60.
[0025] The circular assembly 60 includes multiple mounting plates 61, multiple rotating parts 62 rotatably connected to adjacent mounting plates 61, a positioning shaft 63 disposed on the rotating parts 62, two guide shafts 64 disposed on the mounting plates 61, and multiple precision circular assemblies 65 disposed on the mounting plates 61.
[0026] The mounting plates 61 are used to mount the precision-assembled circular components 65 in a one-to-one correspondence, and the stator core is mounted on the precision-assembled circular components 65. Multiple mounting plates 61 are arranged in a straight line, and adjacent mounting plates 61 are rotatably connected by rotating members 62, thereby connecting multiple mounting plates 61 into a whole and allowing multiple mounting plates 61 to rotate around the rotating member 62. The rotating member 62 is provided with locking components such as snap rings to facilitate its installation.
[0027] Two guide shafts 64 are respectively disposed on the mounting plates 61 located at both ends of the plurality of mounting plates 61 and are respectively slidably disposed in the two guide grooves 31. When the first linear drive device 40 drives the guide plate 30 to move, the guide shafts 64 slide in the guide grooves 31, thereby bringing the two ends of the two rounding components 60 closer to each other, so that the plurality of mounting plates 61 of the two rounding components 60 change from the original straight line arrangement to an arc arrangement, and are assembled on the circular core 51 so that the plurality of stators are assembled into a circle, completing the rough rounding of the stators. However, at this time, there are still gaps between the stator cores, which need to be squeezed by the fine rounding component 65.
[0028] The width of the multiple mounting plates 61 gradually decreases towards the center of the circular core 51, making the outer contour of the mounting plates 61 an isosceles trapezoid, thus preventing them from interfering with each other when arranged in an arc shape. The ends of the multiple mounting plates 61 facing the circular core 51 are arc-shaped and bend away from the circular core 51 to form a second positioning groove 66. When the multiple mounting plates 61 change from a straight line arrangement to an arc arrangement, the position of the rotating member 62 located in the middle remains unchanged. Therefore, the positioning shaft 63 connects the rotating member 62 located in the middle position among the multiple rotating members 62 to the fixing frame 50, thereby allowing the multiple mounting plates 61 to be stably mounted on the fixing frame 50.
[0029] The precision-assembled circular assembly 65 includes a second guide rail 651 disposed on the mounting plate 61, a fixing plate 652 disposed on the mounting plate 61, a push block 653 slidably disposed on the second guide rail 651, a second linear drive device 654 disposed on the fixing plate 652, a limiting shaft 655 disposed on the push block 653, two limiting blocks 656 disposed on the push block 653, and two adjusting bolts 657 respectively adjustablely disposed on the limiting blocks 656.
[0030] The output end of the second linear drive device 654 is connected to the push block 653 and is used to drive the push block 653 to reciprocate along the second guide rail 651. The push block 653 is used to place the stators that need to be joined together. Since the push block 653 and the second linear drive device 654 are respectively mounted on the mounting plate 61 via the second guide rail 651 and the fixing plate 652, when the multiple mounting plates 61 rotate, they will also drive the entire fine-jointing assembly 65 to change direction, so that the output direction of the second linear drive device 654 faces the circular core 51. Then, the second linear drive device 654 drives the push block 653 to move, so that the multiple stators mounted on the push block 653 are pressed against each other, thereby ensuring that there are no gaps between the stators and achieving tight joining. Subsequently, subsequent steps such as welding and fixing can be performed.
[0031] The limiting shaft 655 is vertically disposed at the bottom of the push block 653. When multiple stators are coarsely assembled, the push block 653 is located in the second positioning groove 66. When multiple stators are moved and squeezed for fine assembly, the push block 653 is located in the first positioning groove 52.
[0032] The limiting blocks 656 are respectively disposed on both sides of the push block 653 and move together with the push block 653. The adjusting bolts 657 are adjustablely inserted into the push block 653, and the fixing plate 652 is located in the moving direction of the limiting blocks 656. When the push block 653 moves to its limit position, the adjusting bolts 657 abut against the fixing plate 652, thereby preventing further movement and achieving the purpose of limiting movement to avoid excessive compression and damage to the stator. By adjusting the insertion depth of the adjusting bolts 657, the moving distance of the push block 653 can be adjusted to accommodate different specifications of circular joints.
[0033] Compared with the prior art, the integrated coil coarse and fine rounding mechanism provided by this utility model drives the guide plate 30 to slide along the first guide rail 20 through the first linear drive device 40, thereby moving the rounding assembly 60. This causes the guide shafts 64 located at both ends of the rounding assembly 60 to slide within the inclined guide grooves 31 of the guide plate 30, forcing the multiple mounting plates 61 of the two sets of rounding assemblies 60 to change from a linear arrangement to an arc arrangement around the circular core 51 of the fixing frame 50, thus completing the coarse rounding. Subsequently, the second linear drive device 654 in the fine rounding assembly 65 located on the mounting plate 61 drives the push block 653 to move along the second guide rail 651 toward the center of the circular core 51, squeezing the stator to eliminate gaps. This system achieves seamless integration and unified completion of rough and fine stator assembly in the same workstation, completely eliminating the need for transfer to the fine assembly station or fixture change after rough assembly, as required in traditional processes. This significantly simplifies the process flow, greatly improves assembly efficiency, and effectively avoids potential displacement or misalignment of the stator core during transfer, ensuring assembly accuracy and stability. Simultaneously, the adjusting bolt 657 allows for convenient and precise adjustment of the extension length of the push block 653, thereby flexibly controlling the fine assembly extrusion stroke limit. This enables the mechanism to quickly and accurately adapt to the assembly requirements of stator cores with different thicknesses.
[0034] The above are merely preferred embodiments of the present utility model and are not intended to limit the scope of protection of the present utility model. Any modifications, equivalent substitutions or improvements within the spirit of the present utility model are covered within the scope of the claims of the present utility model.
