Description
Technical Field
[0001] This application relates to the field of motor manufacturing technology, and in particular to a tooling for assembling stator laminations. Background Technology
[0002] Stator lamination splicing and stacking fixture is a core auxiliary equipment in motor stator manufacturing. It is mainly used to accurately position and stack single or spliced units of stamped stator silicon steel laminations layer by layer, and form stator core lamination groups that meet design requirements by pressing and fixing them. To solve the problem of difficulty in forming a regular, high-strength stator core after individual processing of loose silicon steel sheets, a pre-set positioning structure, such as positioning pins and positioning grooves, is used to ensure that the key parts such as the punching holes and tooth grooves of each silicon steel sheet are fully aligned, so as to avoid misalignment during stacking, which would lead to difficulties in subsequent motor assembly or increased magnetic circuit loss. Traditional manual lamination methods rely on workers' experience to align the positioning holes and slots of the laminations, which has problems such as low positioning accuracy, which can lead to deviations in subsequent winding installation, slow lamination efficiency, time-consuming alignment of each lamination, and easy scratching of the edges of the laminations, affecting insulation performance. To address these issues, a stator lamination splicing and lamination tooling is proposed. Utility Model Content
[0003] The purpose of this application is to provide a stator lamination splicing tooling, which aims to improve the traditional manual splicing method that relies on workers' experience to align the positioning holes and slots of the laminations. This method suffers from problems such as low positioning accuracy (which can easily lead to deviations in subsequent winding installation), slow splicing efficiency (time-consuming alignment of each lamination), and easy scratching of the edges of the laminations.
[0004] The stator lamination splicing and stacking fixture provided in this application adopts the following technical solution: A stator lamination assembly tooling includes a worktable, an installation mechanism fixedly connected to the top of the worktable, a connecting platform fixedly connected to the top of the installation mechanism, a calibration mechanism mounted on the top of the connecting platform, and a combination mechanism mounted on the top of the calibration mechanism. The installation mechanism includes a base, the bottom of which is fixedly connected to the top of the workbench. A protective cover is fixedly connected inside the base, and a pneumatic cylinder is fixedly connected inside the protective cover. A connecting plate is fixedly connected to the drive end of the pneumatic cylinder, and multiple fixing blocks are fixedly connected to the outside of the connecting plate. A follower plate is rotatably connected inside the fixing blocks, and a limiting component is rotatably connected to the other end of the follower plate. Through the above technical solution: the workbench provides stable support for the entire tooling, the installation mechanism is firmly connected to the workbench with the base to ensure structural stability, the protective cover can isolate dust and impurities to prevent them from affecting the operation of internal components such as the pneumatic cylinder and extend the service life of the components, after the pneumatic cylinder is started, its driving force is evenly transmitted to multiple fixed blocks through the connecting plate, the fixed blocks drive the follower plate to rotate, and the follower plate then drives the movement of the limiting component, which can achieve precise fixation of the combined mechanism. At the same time, the connecting platform realizes the precise docking of the installation mechanism and the calibration mechanism, laying the foundation for the subsequent positioning and stacking of the loose pieces, effectively improving the efficiency and accuracy of stator loose piece splicing and stacking.
[0005] Preferably, the calibration mechanism includes a positioning turntable, the interior of which is fixedly connected a plurality of positioning holes, the interior of which is slidably connected a positioning pin, the interior of which is fixedly connected two springs, and the other end of the spring is fixedly connected to a limit bead. By adopting the above technical solution, the positioning turntable provides a unified placement benchmark for the loose pieces, ensuring that the initial position of the loose pieces is consistent each time they are stacked. The positioning hole provides an installation guide for the positioning pin, limiting its radial offset. After the positioning pin is inserted into the through hole of the loose pieces, the position of the loose pieces can be accurately calibrated, avoiding misalignment during stacking. At the same time, the spring pushes the limit bead to lock the positioning hole, which can firmly fix the positioning pin and prevent it from falling off during operation. Moreover, the limit bead can extend and retract flexibly during loading and unloading, which facilitates quick disassembly and assembly of the positioning pin. This not only ensures the calibration accuracy but also improves the ease of operation of the tooling.
[0006] Preferably, a limiting groove is formed inside the positioning hole, and the limiting bead is slidably connected to the inside of the limiting groove. By adopting the above technical solution, the limiting groove and the limiting bead form a matching structure. After the spring pushes the limiting bead into the limiting groove, it can limit the axial displacement of the positioning pin in the positioning hole, prevent it from falling off accidentally, and ensure that the positioning pin is installed firmly. At the same time, the sliding connection design allows the limiting bead to smoothly disengage from the limiting groove, which facilitates the disassembly and replacement of the positioning pin, taking into account both the reliability of fixation and the convenience of operation.
[0007] Preferably, the outer part of the limiting bead is slidably connected to the inside of the positioning pin, and the bottom of the positioning pin is movably connected to the top of the connecting platform; By adopting the above technical solution, the limiting bead is slidably connected inside the positioning pin and can flexibly extend and retract under the action of the spring. It can not only be smoothly inserted into the limiting groove to fix the positioning pin, but also be easily disengaged during disassembly to avoid jamming and improve the efficiency of mounting and dismounting the positioning pin.
[0008] Preferably, the assembly mechanism includes a group of loose pieces, the group of loose pieces having multiple limiting holes inside and multiple through holes inside; By adopting the above technical solution, the loose sheet group, as the basic component of the stator core, has through holes that can be precisely matched with the positioning pins of the alignment mechanism. With the guidance of the positioning pins, the key parts such as the tooth grooves and punching holes of each loose sheet are aligned, avoiding errors during stacking.
[0009] Preferably, the limiting component includes multiple sliding plates, the bottom of which is rotatably connected to one end of the follower plate, and the top of which is fixedly connected to the limiting plate; By adopting the above technical solution, when the follower plate rotates, it can drive the skateboard connected to it at the bottom to move synchronously, smoothly converting the rotational motion of the follower plate into the horizontal linear motion of the skateboard, and avoiding jamming during power transmission.
[0010] Preferably, the external part of the limiting plate is movably connected to the inside of the loose piece group, and the external part of the limiting plate is slidably connected to the inside of the protective cover; By adopting the above technical solution, the external limiting plate is movably connected to the inside of the loose piece group, which can be accurately inserted into the limiting hole of the loose piece group, firmly fixing the loose piece group radially, reducing displacement and shaking during stacking, avoiding scratches on the loose pieces, and ensuring the structural integrity of the loose piece group.
[0011] Preferably, the outer part of the positioning pin is slidably connected to the inside of the through hole, and the bottom of the loose piece group is movably connected to the top of the positioning turntable; By adopting the above technical solution, the positioning pin is slidably connected in the through hole, which can accurately limit the circumferential displacement of the loose piece group and ensure the alignment of the key parts of each loose piece. The bottom of the loose piece group is movably connected to the positioning turntable, which provides stable support and ensures the horizontality of the loose piece group when it is stacked. The dual cooperation effectively avoids stacking misalignment and improves the processing accuracy of the stator core.
[0012] In summary, this application includes at least one of the following beneficial technical effects: 1. In this utility model, the pneumatic cylinder is activated, which drives the connecting plate to move, causing the fixing block to pull the follower plate to rotate, thereby pushing the sliding plate to move horizontally, allowing the limiting plate to be inserted into the limiting hole of the loose piece group, fixing the loose piece group radially, reducing installation jamming and shaking, avoiding scratches on the loose pieces, ensuring stacking stability, and providing qualified stator core semi-finished products for subsequent processes.
[0013] 2. In this utility model, when in use, first place the positioning turntable on the top of the connecting platform, then slide the bottom of the positioning pin into the positioning hole. At this time, the spring pushes the limiting bead into the limiting groove to achieve a stable installation of the positioning pin. Then, align the through hole of the loose piece group with the positioning pin and insert it. The two work together to limit the circumferential displacement of the loose piece group and ensure that the key parts of each loose piece are aligned. Attached Figure Description

[0015] The following is in conjunction with the appendix Figure 1 - Appendix Figure 4 This application will be described in further detail below.
[0016] Example: A stator lamination assembly tooling, referring to... Figures 1 to 3 The system includes a workbench 1, a mounting mechanism 2 fixedly connected to the top of the workbench 1, a connecting platform 3 fixedly connected to the top of the mounting mechanism 2 (which serves as a connecting element), and a calibration mechanism 4 mounted on the top of the connecting platform 3. A combination mechanism 5 is mounted on the top of the calibration mechanism 4. The mounting mechanism 2 includes a base 27, the bottom of which is fixedly connected to the top of the workbench 1, enhancing the connection between the mounting mechanism 2 and the workbench 1. A protective cover for protecting internal components is fixedly connected inside the base 27. 21. The protective cover 21 can effectively prevent external dust and impurities from entering the interior and affecting the operation of the components. The protective cover 21 has a pneumatic cylinder 22 that provides power output fixedly connected inside. The drive end of the pneumatic cylinder 22 is fixedly connected to a connecting plate 23 for transmitting power. The connecting plate 23 can evenly transmit the driving force of the pneumatic cylinder 22 to each fixed block 24. Multiple fixed blocks 24 for driving the follower plate 25 to move are fixedly connected outside the connecting plate 23. The follower plate 25 for transmitting power is rotatably connected inside the fixed block 24. The follower plate 25 can change the direction of force transmission by rotating. Specifically, the mounting mechanism 2 is securely connected to the workbench 1 via the base 27, providing solid support for the entire tooling. The protective cover 21 inside the base 27 forms a closed space, effectively isolating dust and impurities and ensuring the stable operation of internal components such as the pneumatic cylinder 22. When the pneumatic cylinder 22 is started, its drive end drives the connecting plate 23 to move up and down. The connecting plate 23 evenly distributes the power to multiple fixed blocks 24. When the fixed blocks 24 move with the connecting plate 23, they drive the follower plate 25, which is rotatably connected to them, to rotate synchronously. The follower plate 25 changes the direction of force transmission by changing its angle, thereby driving the subsequent limiting component 26 to move. The connecting platform 3 is fixed to the top of the mounting mechanism 2, providing an installation benchmark for the calibration mechanism 4 and ensuring the positional accuracy of the mounting mechanism 2 and the calibration mechanism 4, thus achieving coordinated cooperation between power transmission and positioning functions.
[0017] Reference Figure 1 , Figure 2 and Figure 4 The calibration mechanism 4 includes a positioning turntable 41, which ensures the consistency of the placement position of the loose piece group 51. Multiple positioning holes 42 for installing positioning pins 43 are fixedly connected inside the positioning turntable 41. The positioning holes 42 provide installation space for the positioning pins 43 and limit their radial displacement. Positioning pins 43 for guiding the positioning of the loose piece group 51 are slidably connected inside the positioning holes 42. The positioning pins 43 can be inserted into the through holes 53 of the loose piece group 51 for precise guidance. Two springs 44 for providing elastic force are fixedly connected inside the positioning pins 43. The springs 44 can push the limiting beads 45 to lock in place through their own elasticity. The other end of the springs 44 is fixedly connected to the limiting beads 45 for fixing the positioning pins 43. The limiting beads 45 can be locked in place under the action of the springs 44. The limiting groove 46 prevents the positioning pin 43 from falling out of the positioning hole 42. The positioning hole 42 has a limiting groove 46 inside for fixing the limiting bead 45. The cooperation between the limiting groove 46 and the limiting bead 45 can realize the stable installation of the positioning pin 43 in the positioning hole 42. The external of the limiting bead 45 is slidably connected to the inside of the limiting groove 46 to ensure that the limiting bead 45 can smoothly enter or leave the limiting groove 46, which facilitates the installation and removal of the positioning pin 43. The external of the limiting bead 45 is slidably connected to the inside of the positioning pin 43, so that the limiting bead 45 can flexibly extend and retract within the positioning pin 43 to adapt to the position change of the limiting groove 46. The bottom of the positioning pin 43 is movably connected to the top of the connecting platform 3. The connecting platform 3 can provide bottom support for the positioning pin 43 and enhance the stability of the positioning pin 43. Specifically, the calibration mechanism 4 uses the positioning turntable 41 as the reference carrier, which is placed on the top of the connecting platform 3 to ensure that the loose piece group 51 is placed in the same position each time. The positioning hole 42 on the positioning turntable 41 provides an installation position for the positioning pin 43 and restricts its radial displacement. The bottom of the positioning pin 43 is movably connected to the connecting platform 3 to obtain support. When inserted into the positioning hole 42, the internal spring 44 pushes the limit bead 45 to extend and retract, so that it is locked into the limit groove 46 of the positioning hole 42, so that the positioning pin 43 is stably installed and easy to install and remove.
[0018] Reference Figure 1 and Figure 2The assembly mechanism 5 includes a piece group 51, which is the processing object of the stacking tooling and will eventually form a stator core. The piece group 51 has multiple limiting holes 52 inside for fixing with the limiting component 26. The limiting holes 52 can mate with the limiting plate 262 for further fixing. First, the positioning turntable 41 is placed stably on top of the connecting platform 3 to provide a reference for subsequent positioning. Then, the bottom of the positioning pin 43 is slid into the positioning hole 42. At this time, the spring 44 inside the positioning pin 43 is compressed, generating elastic force, which pushes the limiting bead 45 into the limiting groove 46, achieving a stable installation of the positioning pin 43 and preventing it from loosening or falling off during operation. Finally, the through hole 53 of the piece group 51 is aligned with the positioning pin 43 and inserted. The precise engagement of the positioning pin 43 and the through hole 53 restricts the circumferential displacement of the loose sheet assembly 51, ensuring accurate alignment of key parts such as the tooth grooves and punching holes of each loose sheet, laying the foundation for stacking accuracy. After initial positioning, the pneumatic cylinder 22 is activated, and its drive end moves the connecting plate 23. The connecting plate 23 pulls the follower plate 25 to rotate through the fixing block 24. The other end of the follower plate 25 pushes the sliding plate 261 to move horizontally, so that the limiting plate 262 is inserted into the limiting hole 52 of the loose sheet assembly 51, further fixing the loose sheet assembly 51 radially, reducing jamming and shaking during installation, preventing scratches on the surface of the loose sheets, and ensuring the overall stability of the loose sheet assembly 51 during stacking, providing a high-quality stator core for subsequent forming processes. The semi-finished piece group 51 is positioned such that its interior has multiple through holes 53 for positioning with locating pins 43. The engagement of the through holes 53 with the locating pins 43 ensures the accurate relative position of each piece, preventing misalignment during stacking. The limiting component 26 includes multiple sliding plates 261, which can move horizontally under the drive of the follower plate 25. The bottom of the sliding plate 261 is rotatably connected to one end of the follower plate 25, so that the rotation of the follower plate 25 is converted into the translation of the sliding plate 261. The top of the sliding plate 261 is fixedly connected to a limiting plate 262 for directly fixing the piece group 51. The limiting plate 262 can be inserted into the limiting hole 52 to achieve radial fixing of the piece group 51. The external surface of the limiting plate 262 is movable. The movable connection is inside the loose piece group 51, and can be fixed by inserting into the limiting hole 52 of the loose piece group 51 to reduce shaking during the stacking process. The external sliding connection of the limiting plate 262 is inside the protective cover 21. The protective cover 21 can limit the movement direction of the limiting plate 262 to ensure its smooth movement. The external sliding connection of the positioning pin 43 is inside the through hole 53. Through the cooperation of the positioning pin 43 and the through hole 53, the circumferential position of the loose piece group 51 can be precisely limited to ensure that the key parts such as the tooth groove and punching hole of each loose piece are aligned. The bottom of the loose piece group 51 is movably connected to the top of the positioning turntable 41. The positioning turntable 41 can provide a bottom support surface for the loose piece group 51 to ensure the levelness of the loose piece group 51 during the stacking process. Specifically, in the assembly mechanism 5, the loose piece group 51, as the processing object, needs to be stacked in cooperation with the limiting component 26 and the calibration mechanism 4. The limiting hole 52 of the loose piece group 51 is adapted to the limiting plate 262 of the limiting component 26. When the follower plate 25 rotates, the sliding plate 261 connected to it at the bottom will move horizontally, causing the limiting plate 262 at the top to be inserted into the limiting hole 52. At the same time, the protective cover 21 restricts the movement direction of the limiting plate 262, thereby fixing the loose piece group 51 radially and reducing stacking wobbling. The through hole 53 of the loose piece group 51 is slidably engaged with the positioning pin 43 to precisely limit its circumferential position, ensuring that the tooth grooves and punching holes of each loose piece are aligned and avoiding stacking misalignment. Furthermore, the bottom of the loose piece group 51 is placed on the top of the positioning turntable 41, which provides a stable support surface to ensure the horizontality during stacking. Ultimately, the loose piece group 51 can be stacked stably, laying the foundation for the subsequent formation of a qualified stator core.
[0019] Working principle: In use, first place the positioning turntable 41 stably on the top of the connecting platform 3 to provide a reference for subsequent positioning. Then, slide the bottom of the positioning pin 43 into the positioning hole 42. At this time, the spring 44 inside the positioning pin 43 is compressed and generates elastic force, pushing the limit bead 45 into the limit groove 46, realizing the stable installation of the positioning pin 43 and preventing it from loosening or falling off during operation. Then, align the through hole 53 of the loose piece group 51 with the positioning pin 43 and fit it in. Through the precise cooperation between the positioning pin 43 and the through hole 53, the circumferential displacement of the loose piece group 51 is restricted, ensuring that the key parts such as the tooth groove and punching hole of each loose piece are accurately aligned, laying the foundation for the stacking accuracy.
[0020] After initial positioning is completed, the pneumatic cylinder 22 is activated, and its driving end drives the connecting plate 23 to move. The connecting plate 23 pulls the follower plate 25 to rotate through the fixing block 24. The other end of the follower plate 25 pushes the slide plate 261 to move horizontally, so that the limiting plate 262 is inserted into the limiting hole 52 of the loose piece group 51, further fixing the loose piece group 51 radially, reducing jamming and shaking during installation, avoiding scratches on the surface of the loose pieces, and ensuring the overall stability of the loose piece group 51 when stacked, providing a high-quality stator core semi-finished product for subsequent forming processes.
