Description

Technical Field

[0001] This utility model relates to the field of motor manufacturing technology, and in particular to a stator assembly device. Background Technology

[0002] In traditional stator manufacturing processes, small-sized stators are typically produced using a modular production method: the stator core is first divided into multiple independent modules, which are then manufactured separately using a winding machine. After all the stator modules are wound, they are manually assembled into a circle. The modules are then mounted onto a prefabricated assembly frame and secured magnetically. Because the stator modules are small, manual assembly is inefficient and cannot meet the demands of rapid production. Furthermore, the resulting stator end faces are uneven, affecting subsequent stator module assembly and increasing manufacturing costs. Utility Model Content

[0021] Please see Figure 1 and Figure 4 This utility model provides a stator assembly device, including a worktable 2, a feeding mechanism 3, a pre-pressing mechanism 4 and a lifting mechanism 5 disposed on the worktable 2; the worktable 2 is provided with a mounting frame 21 in the working area, the feeding mechanism 3 transports the stator 1 to the working area, the pre-pressing mechanism 4 is disposed on the mounting frame 21 and located above the feeding mechanism 3, and the lifting mechanism 5 is disposed on the mounting frame 21 and located below the feeding mechanism 3. The worktable 2 is provided with a first clearance hole through which the lifting component 51 passes, and the conveying table 31 is provided with a second clearance hole 311 through which the lifting component 51 passes.

[0022] Combination Figure 2 and Figure 4 The feeding mechanism 3 includes a conveyor 31 disposed between the workbench 2 and the mounting frame 21, a fixed frame 32 slidably disposed on the conveyor 31, a sliding assembly 33 for driving the fixed frame 32 to slide relative to the conveyor 31, and two clamping assemblies 34 disposed opposite to each other on the fixed frame 32 for assembling the stator 1. The fixed frame 32 is provided with a placement seat 321 for placing the stator 1 between the two clamping assemblies 34. The placement seat 321 is provided with a third clearance hole 32 through which the lifting assembly 51 passes and into which part of the stator 1 is inserted. 2. A fixing member 323 for fixing the stator 1 is provided on the top surface of the placement base 321 and around the third clearance hole 322. When assembling the connecting stator 1 into a circle, the sliding component 33 of the feeding mechanism 3 transports the fixing frame 32 on the conveyor table 31 to a location close to the operator for manual loading. The operator places the stator 1 in the third clearance hole 322 of the placement base 321 and uses the fixing member 323 for limiting and fixing. Two opposing clamping components 34 clamp the stator 1 on the placement base 321 from both sides to assemble the circle. The specific structure of the fixing member 323 is not limited here; optionally, the fixing member 323 can be a fixing rod, on which the connecting frame of the stator 1 is sleeved, and the stator 1 is stably placed in a preset position in the third clearance hole 322 of the placement base 321, which facilitates loading and unloading by the operator and helps to improve work efficiency.

[0023] It should be noted that the pre-compression mechanism 4 is disposed on the mounting frame 21 and located above the conveyor table 31. The pre-compression mechanism 4 includes a pre-compression component 41 for pre-compressing the upper end face of the stator 1, and a first lifting component 42 for driving the pre-compression component 41 to move up and down relative to the mounting frame 21. The mounting frame 21 is provided with a first through hole for the pre-compression component 41 to pass through. The lifting mechanism 5 is disposed on the mounting frame 21 and located below the conveyor table 31. The lifting mechanism 5 includes a lifting component 51 for flattening the lower end face of the stator 1, and a second lifting component 52 for driving the lifting component 51 to move up and down relative to the mounting frame 21. The mounting frame 21 is provided with a first through hole for the pre-compression component 41 to pass through. The second through hole allows the lifting assembly 51 to pass through; when the sliding assembly 33 transports the fixed frame 32 containing the stator 1 to the work area, the first lifting assembly 42 of the pre-compression mechanism 4 drives the pre-compression assembly 41 to move downward relative to the mounting frame 21, passing through the first through hole of the mounting frame 21 and pre-compressing the upper end surface of the stator 1; the second lifting assembly 52 of the lifting mechanism 5 drives the lifting assembly 51 to move upward relative to the mounting frame 21, passing through the first clearance hole of the worktable 2, the second clearance hole 311 of the conveying table 31, the second through hole of the mounting frame 21, and the third clearance hole 322 of the placement seat 321 in sequence, and flattening the lower end surface of the stator 1.

[0024] Compared with the prior art, the beneficial effects of this utility model are as follows: the stator assembly device enables the automated assembly of small-sized continuous stator blocks 1, improving work efficiency and meeting the needs of rapid production. At the same time, after assembly, the end face of stator 1 is flattened to make the end face of stator 1 flat, avoiding the impact on subsequent stator module assembly and helping to reduce manufacturing costs.

[0025] In one embodiment of this application, please refer to Figures 1 to 4 The sliding component 33 of the feeding mechanism 3 includes a slide rail 331 mounted on the conveyor table 31, a slider slidably mounted on the slide rail 331 and fixedly connected to the bottom of the fixed frame 32, a telescopic push rod 332 fixedly connected to the fixed frame 32, and a telescopic motor 333 for driving the telescopic push rod 332 to telescopically move. By mounting the slide rail 331 on the conveyor table 31 and using the slider slidably mounted on the slide rail 331 to fix the bottom of the fixed frame 32, when the telescopic motor 333 drives the telescopic push rod 332 to telescopically move, the fixed frame 32 slides back and forth along the preset path of the slide rail 331 between the worker's loading area and the work area of ​​the worktable 2 under the transmission action of the telescopic push rod 332, which facilitates the worker's loading and unloading and improves work efficiency.

[0026] Specifically, limiting blocks 312 that movably abut against the fixed frame 32 are respectively provided on opposite sides of the conveyor table 31 to limit the sliding range of the fixed frame 32. By providing limiting blocks 312 on opposite sides of the conveyor table 31 to limit the sliding range of the fixed frame 32, the fixed frame 32 can be accurately slid to the feeding area and the working area on the worktable 2, so that the pre-pressing mechanism 4 and the lifting mechanism 5 can accurately abut against the stator 1 on the placement seat 321, which is conducive to ensuring the stability and reliability of the stator assembly device.

[0027] In one embodiment of this application, please refer to Figure 4 and Figure 5 The clamping assembly 34 of the feeding mechanism 3 includes a clamping seat 341 slidably disposed on the fixed frame 32, a clamping block 342 disposed on the clamping seat 341, a clamping push rod 343 fixedly connected to the clamping seat 341, and a clamping motor 344 disposed on the fixed frame 32 for driving the clamping push rod 343 to extend and retract. The surface of the clamping block 342 facing the stator 1 is recessed inward to form a clamping groove 3421 for the stator 1 to be partially inserted. The clamping push rod 343 is driven to extend and retract by the clamping motor 344 fixedly connected to the fixed frame 32, thereby driving the clamping seat 341 to slide relative to the fixed frame 32. The movement causes the clamping blocks 342 on the clamping seat 341 to slide relative to the fixed frame 32, so that the two clamping blocks 342 facing each other slide towards or away from each other relative to the fixed frame 32. The surface of the clamping block 342 facing the stator 1 is recessed inward to form a clamping groove 3421 for the stator 1 to be partially inserted. When the two clamping blocks 342 slide towards each other and abut against each other, the two clamping grooves 3421 surround to form a cylindrical shape, which assembles the stator 1 placed on the placement seat 321 into a circle, realizing the automated assembly of small-sized block stators 1, improving work efficiency and meeting the needs of rapid production.

[0028] In one embodiment of this application, please refer to Figure 2 and Figure 6 The first lifting component 42 of the pre-compression mechanism 4 includes a first lifting frame 421 fixedly connected to the mounting frame 21, a first lifting block 422 fixedly connected to the pre-compression component 41, and a first lifting motor 423 disposed on the first lifting frame 421 and used to drive the first lifting block 422 to move up and down relative to the first lifting frame 421. The first lifting motor 423 is stably installed in a preset position by the first lifting frame 421 and is located above the conveyor table 31. The first lifting motor 423 drives the first lifting block 422 to move up and down relative to the first lifting frame 421, thereby driving the pre-compression component 41 to move up and down relative to the first lifting frame 421, thereby applying downward pressure to the upper surface of the stator 1 placed on the placement seat 321.

[0029] Specifically, the pre-compression assembly 41 includes a pre-compression seat 411 fixedly connected to the first lifting block 422, a pre-compression frame 413 fixedly connected to the pre-compression seat 411, multiple pre-compression structures 414 slidably disposed on the pre-compression frame 413 and movably abutting against multiple iron cores 11 on the stator 1, and multiple elastic elements 415 disposed between the pre-compression frame 413 and the multiple pre-compression structures 414. The pre-compression seat 411 is fixedly connected to the first lifting block 422, allowing the entire pre-compression assembly 41 to move with the lifting and lowering movement of the first lifting block 422 relative to the first lifting frame 421, thereby applying downward pressure to the upper surface of the stator 1 on the placement seat 321. The multiple pre-compression structures 414 slidably disposed on the pre-compression frame 413 movably abut against each of the multiple iron cores 11 on the stator 1, thereby applying downward pressure to each iron core 11. Simultaneously, multiple elastic elements 415 are disposed between the pre-compression frame 413 and the multiple pre-compression structures 414. Each iron core 11 corresponds to a different pre-compression structure 414, and each pre-compression structure 414 corresponds to a different elastic element 415, so that the movement between iron cores 11 will not affect each other. When the lifting mechanism 5 flattens the lower end face of the stator 1, part of the iron core 11 of the stator 1 is pushed by the lifting component 51 and moves upward relative to the connecting block frame of the stator 1. The pre-compression structure 414, which abuts against the upper end face of the stator 1, is pushed by the iron core 11 and squeezes the elastic element 415 upward relative to the pre-compression frame 413 to make it contract, and moves upward relative to the pre-compression frame 413. This prevents the stator 1 from being damaged by external force when the lower end face of the stator 1 is flattened. While ensuring that the end face of the stator 1 is flattened after the assembly, the end face of the stator 1 is prevented from being damaged during the processing, effectively avoiding the impact on the subsequent stator module assembly, and helping to reduce manufacturing costs.

[0030] Specifically, the top surface of the preload seat 411 is provided with a guide post 412, and the first lifting frame 421 is provided with a guide hole through which the guide post 412 passes. By providing a guide post 412 on the preload seat 411 and making the guide post 412 pass through the guide hole on the first lifting frame 421, the first lifting assembly 42 can move up and down according to a preset motion trajectory when driving the preload assembly 41 to move up and down relative to the first lifting frame 421, which is beneficial to improving the structural stability and reliability of the stator assembly device.

[0031] In one embodiment of this application, please refer to Figure 2 , Figure 3 , Figure 5 , Figure 6 and Figure 7The second lifting component 52 of the lifting mechanism 5 includes a second lifting frame 521 fixedly connected to the mounting frame 21, a second lifting block 522 movably abutting against the lifting component 51, and a second lifting motor 523 disposed on the second lifting frame 521 for driving the second lifting block 522 to move up and down relative to the second lifting frame 521. The second lifting motor 523 is securely installed in a preset position by the second lifting frame 521 and is located below the conveyor table 31. The second lifting block 522 is driven to move up and down relative to the second lifting frame 521 by the second lifting motor 523. The second lifting block 522 moves upward and movably abuts against the lifting component 51, pushing the lifting component 51 to move upward relative to the mounting frame 21, and sequentially penetrating the first clearance hole of the worktable 2, the second clearance hole 311 of the conveyor table 31, the second through hole of the mounting frame 21, and the third clearance hole 322 of the placement seat 321, and flattening the lower end face of the stator 1.

[0032] In one embodiment of this application, please refer to Figure 6 and Figure 7 The lifting assembly 51 includes a lifting seat 511 fixedly connected to the mounting bracket 21, and a lifting member 512 slidably disposed on the lifting seat 511 and movably abutting against the stator 1. The lifting seat 511 has a through-hole for the lifting member 512 to pass through. The inner wall surface of the lifting seat 511 at the through-hole is recessed to form a lifting guide groove. The outer wall of the lifting member 512 has a lifting protrusion 5121 that matches the lifting guide groove. The lifting assembly 51 is fixedly connected to the mounting bracket 21 through the lifting seat 511, so that the lifting assembly 51 is securely installed in a preset position in the working area, and the lifting member 512 is slidably disposed on the mounting bracket 21. The lifting member 512 is placed in the connecting hole of the lifting seat 511. The lifting guide groove on the lifting seat 511 and the lifting protrusion 5121 on the surface of the lifting member 512 are adapted to each other. Under the driving action of the second lifting assembly 52, the lifting member 512 moves up and down relative to the lifting seat 511 along the lifting guide groove. The movement direction of the lifting member 512 is restricted, so that the lifting member 512 moves up and down relative to the lifting seat 511 according to the preset sliding trajectory. It movably abuts against the lower end face of the stator 1 on the placement seat 321, flattening the lower end face of the stator 1 and making the end face of the stator 1 flat. This avoids affecting the subsequent assembly of the stator module and helps to reduce manufacturing costs.

[0033] Specifically, one end of the lifting member 512 is movably abutted against the second lifting block 522, and the other end is provided with a flattening end face 5122 for flattening the lower end face of the stator 1. The lifting member 512 has a protruding insertion structure 5123 on the flattening end face 5122 for insertion and alignment with the stator 1. The stator 1 is inserted and aligned by the insertion structure 5123 on the lifting member 512, so that the flattening end face 5122 of the lifting member 512 can accurately abut against the lower end face of the stator 1 and flatten it, so that the end face of the stator 1 is flat and avoids affecting the subsequent assembly of the stator module.

[0034] It should be noted that the technical solutions of the various embodiments of this utility model can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.
