Description

Technical Field

[0001] This utility model relates to the field of motor cores, specifically to a motor core. Background Technology

[0002] The motor core is a crucial component of an electric motor, typically composed of stacked silicon steel sheets. Its primary function is to form the magnetic circuit, supporting the generation and conduction of the motor's magnetic field. The design and material selection of the motor core directly affect the motor's efficiency, performance, and operational stability. During the manufacturing process, after the silicon steel sheets are stacked, they need to be connected and fixed together to ensure the stability of the overall structure.

[0003] Currently, the connection and fixation between layers of silicon steel sheets in the production process of motor cores is mainly achieved by placing a connecting strip in the groove reserved on the outside of each layer of silicon steel sheet and welding the connecting strip to each layer of silicon steel sheet. This achieves a reliable connection between the layers of silicon steel sheets. Although the above connection method can achieve a stable connection between the layers of silicon steel sheets, the layer-by-layer welding method is not only cumbersome, but also requires grinding of the weld seam after welding. This results in low connection and fixation efficiency between the layers of silicon steel sheets stacked on the motor core, which is not conducive to efficient connection and fixation of the layers of silicon steel sheets, and thus makes the production and assembly efficiency of the motor core relatively low. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a motor core that can achieve rapid connection and fixation between individual silicon steel sheets without welding, in light of the current state of the technology.

[0005] This utility model is achieved through the following technical solution: This utility model proposes a motor core, comprising multiple layers of single-unit silicon steel sheets, wherein each layer of single-unit silicon steel sheets has a pre-reserved limiting hole, and four connecting strips are installed on the outer side of each layer of single-unit silicon steel sheets. Each connecting strip is equipped with a quick-installation assembly, which includes a second gear, a linkage shaft, a turntable, a storage groove, a first gear, a linkage plate, a guide groove, a screw, a movable insert rod, and a fixed insert rod. The guide groove is opened in the connecting strip, the screw is installed in the guide groove, the linkage plate is installed at the lower part of the screw, the movable insert rod is located at the upper part of the linkage plate opposite to the screw, the fixed insert rod is installed on the connecting strip directly below the movable insert rod, the second gear is installed at the upper part of the screw, the first gear is located on one side of the second gear, the linkage shaft is installed in the middle of the side wall of the first gear opposite to the second gear, the turntable is installed at the end of the linkage shaft away from the first gear, and the storage groove is opened on the outer wall of the connecting strip at the turntable.

[0006] Furthermore, the single silicon steel sheet also has six pre-reserved winding grooves.

[0007] Furthermore, the diameter of the limiting hole matches the diameter of the movable insert rod and the fixed insert rod.

[0008] Furthermore, the screw is rotatably connected to the guide groove, and the screw passes through the linkage plate and is threadedly connected to the linkage plate.

[0009] Furthermore, the linkage plate has a Z-shaped structure, the linkage plate slides in conjunction with the guide groove, and the movable insert rod is welded to the linkage plate.

[0010] Furthermore, the second gear is welded to the screw, and the first gear meshes with the second gear.

[0011] Furthermore, the linkage shaft is welded to the gear, and the linkage shaft is rotatably connected to the connecting bar.

[0012] Furthermore, the turntable is welded to the linkage shaft, the turntable has a built-in paddle plate, and the size of the storage groove is larger than the size of the turntable.

[0013] Compared with the prior art, this utility model has the following advantages:

[0014] This invention utilizes a quick-assembly assembly consisting of a second gear, a linkage shaft, a turntable, a storage groove, a first gear, a linkage plate, a guide groove, a screw, a movable insert rod, and a fixed insert rod, pre-drilled limiting holes on the individual silicon steel sheets of each layer, and installed on the connecting strip on the outer side of the individual silicon steel sheets. When connecting the individual silicon steel tubes of each layer, the turntable, linkage shaft, and first gear first cause the second gear to rotate. During the rotation of the second gear, the screw helps the linkage plate move upwards along the guide groove to its limit position. Then, the fixed insert rod is inserted from the bottom into the limiting hole in the lower individual silicon steel sheet. At this point, the movable insert rod is positioned directly above the limiting hole on the upper single silicon steel sheet. Then, simply rotate the turntable in the opposite direction so that the linkage plate moves downward under the action of the linkage shaft, gear one, gear two, and screw. During the downward movement of the linkage plate, the movable insert rod can be inserted into the limiting hole on the upper single silicon steel sheet. Thus, the single silicon steel sheets of each layer are quickly connected under the action of the movable insert rod and the fixed insert rod. Because this connection method eliminates the tedious operation of welding and fixing the single silicon steel sheets of each layer during connection, the production and assembly efficiency of the motor core is improved.

[0022] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.

[0023] like Figures 1-3As shown, a motor core in this embodiment includes multiple layers of single-unit silicon steel sheets 1, each layer of single-unit silicon steel sheet 1 having a pre-drilled limiting hole 5. Four connecting strips 2 are installed on the outer side of each layer of single-unit silicon steel sheets 1. Each connecting strip 2 has a quick-release assembly 4 installed on it. The quick-release assembly 4 includes a second gear 401, a linkage shaft 402, a turntable 403, a storage groove 404, a first gear 405, a linkage plate 406, a guide groove 407, a screw 408, a movable insert rod 409, and a fixed insert rod 4010. The guide groove 407 is formed within the connecting strip 2, and the screw 408 is mounted on the guide groove 4010. Inside the slide groove 407, the linkage plate 406 is installed at the lower part of the screw 408, the movable insert rod 409 is located at the upper part of the linkage plate 406 opposite to the screw 408, the fixed insert rod 4010 is installed on the connecting strip 2 directly below the movable insert rod 409, the second gear 401 is installed at the upper part of the screw 408, the first gear 405 is located on one side of the second gear 401, the linkage shaft 402 is installed in the middle of the side wall of the first gear 405 opposite to the second gear 401, the turntable 403 is installed at the end of the linkage shaft 402 away from the first gear 405, and the storage groove 404 is opened on the outer wall of the connecting strip 2 at the turntable 403;

[0024] This invention provides a motor core that enables rapid connection and fixation between individual silicon steel sheets 1 without welding. It solves the problem of existing motor cores where, during production, the connection and fixation between silicon steel sheets primarily involves placing a connecting strip in a pre-drilled groove on the outer side of each silicon steel sheet and welding the connecting strip to the sheet. While this method achieves stable connection, the layer-by-layer welding is cumbersome and requires grinding the weld seams after welding, resulting in low efficiency in connecting and fixing the stacked silicon steel sheets. This leads to low production and assembly efficiency for the motor core. This invention provides a comprehensive solution to these problems. The approach is as follows: When connecting the individual silicon steel sheets 1, the turntable 403, the linkage shaft 402, and the first gear 405 first cause the second gear 401 to rotate. During the rotation of the second gear 401, the screw 408 helps the linkage plate 406 move upwards along the guide groove 407 to its limit position. Then, the fixed insertion rod 4010 is inserted from the bottom into the limiting hole 5 in the lower individual silicon steel sheet 1. At this time, the movable insertion rod 409 is located on the upper side... Above the limiting hole 5 on the single silicon steel sheet 1, simply rotate the turntable 403 in the opposite direction so that the linkage plate 406 moves down under the action of the linkage shaft 402, gear 1 405, gear 2 401 and screw 408. During the downward movement of the linkage plate 406, the movable insert rod 409 can be inserted into the limiting hole 5 on the upper single silicon steel sheet 1, thereby achieving rapid connection of each layer of single silicon steel sheets 1 under the action of the movable insert rod 409 and the fixed insert rod 4010.

[0025] like Figure 1 As shown, the single silicon steel sheet 1 also has a pre-reserved winding groove 3, and there are six winding grooves 3.

[0026] As one implementation method, the winding groove 3 is mainly used to achieve reliable winding of the wires on the motor, so as to ensure convenient use of the motor core after assembly.

[0027] like Figure 1 and Figure 4 As shown, the diameter of the limiting hole 5 matches the diameter of the movable insertion rod 409 and the fixed insertion rod 4010.

[0028] In one implementation, after the movable insert 409 and the fixed rod are inserted into the limiting hole 5, a reliable connection is achieved between the individual silicon steel sheets 1 of each layer.

[0029] like Figure 2 and Figure 3As shown, the screw 408 is rotatably connected to the guide groove 407, and the screw 408 passes through the linkage plate 406 and is threadedly connected to the linkage plate 406.

[0030] As one implementation method, the rotating connection installation method makes the rotation adjustment of the screw 408 relative to the guide groove 407 more convenient. After the screw 408 rotates, the linkage plate 406 will be easily lifted under the guidance of the threaded transmission and the linkage plate 406.

[0031] like Figure 2 , Figure 3 and Figure 5 As shown, the linkage plate 406 has a Z-shaped structure, and the linkage plate 406 is slidably engaged with the guide groove 407. The movable insert rod 409 is welded to the linkage plate 406.

[0032] As one implementation method, the sliding fit installation method makes it more convenient for the linkage plate 406 to slide and adjust with the guide groove 407. Welding the movable rod 409 to the linkage plate 406 can ensure that the movable rod 409 moves and adjusts synchronously with the linkage plate 406.

[0033] like Figure 2 and Figure 3 As shown, gear 2 401 is welded to screw 408, and gear 1 405 meshes with gear 2 401.

[0034] As one implementation method, welding gear 401 to screw 408 can ensure that screw 408 rotates synchronously with gear 401, and gear 405 can transmit the power transmitted by linkage shaft 402 to screw 408 via gear 401.

[0035] like Figure 2 and Figure 3 As shown, the linkage shaft 402 is welded to the gear 405, and the linkage shaft 402 is rotatably connected to the connecting bar 2.

[0036] As one implementation method, the rotating connection installation method allows the linkage shaft 402 to rotate synchronously with the connecting strip 2.

[0037] like Figure 2 and Figure 3 As shown, the turntable 403 is welded to the linkage shaft 402. The turntable 403 has a built-in paddle plate, and the size of the storage slot 404 is larger than the size of the turntable 403.

[0038] As one implementation method, the storage slot 404 can reliably store the turntable 403, so as to conveniently hide the turntable 403 after use and ensure the overall aesthetics of the connecting strip 2.

[0039] The specific implementation process of this embodiment is as follows: In use, firstly, under the action of the turntable 403 and the linkage shaft 402, gear one 405 rotates. After gear one 405 rotates, gear two 401 rotates. During the rotation of gear two 401, the screw 408 is used to move the linkage plate 406 upwards along the guide groove 407 to its limit position. Then, the fixed insertion rod 4010 is inserted from the bottom into the limiting hole 5 in the lower single silicon steel sheet 1. At this time, the movable insertion rod 409 is located directly above the limiting hole 5 on the upper single silicon steel sheet 1. Then, simply turn the turntable 403... 3. Reverse rotation, so that the linkage plate 406 moves down under the action of the linkage shaft 402, gear 1 405, gear 2 401 and screw 408. During the downward movement of the linkage plate 406, the movable insert rod 409 can be inserted into the limiting hole 5 on the upper single silicon steel sheet 1. Thus, under the action of the movable insert rod 409 and the fixed insert rod 4010, the single silicon steel sheets 1 of each layer can be quickly connected. Since this connection method eliminates the cumbersome operation of welding and fixing the single silicon steel sheets 1 of each layer during connection, the production and assembly efficiency of the motor core is improved.

Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention.
