[0029] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0030] like Figures 1 to 8As shown, a motor stator assembly device is used to assemble an intermediate shaft, a lower stator module, and an upper stator module into a motor. The motor stator assembly device includes a frame 1, with a track 11 at its bottom. A first slide 21 and a second slide 22 are slidably connected to the track 11. An intermediate shaft positioning component 3 and a lower stator module positioning component 4 are mounted on the top surface of the first slide 21, and an upper stator module positioning component 5 is mounted on the top surface of the second slide 22.

[0031] Specifically, such as Figure 3 As shown, the intermediate shaft positioning assembly 3 includes a first positioning seat 31 and an upper positioning ring block 32 and a lower positioning ring block 33 coaxially disposed on the first positioning seat 31. The first positioning seat 31 is connected to the first slide table 21. A set of claws 34 are spaced circumferentially on the lower positioning ring block 33, and these claws 34 can slide radially along the lower positioning ring block 33.

[0034] like Figure 4 As shown, the stator lower module positioning assembly 4 includes a second positioning seat 41 and a first positioning block 42 disposed on the second positioning seat 41. The top surface of the first positioning block 42 has one or more first positioning grooves 43 arranged coaxially. A set of first positioning pins 44 are disposed within each first positioning groove 43. In this embodiment, the stator lower module is precisely positioned using the first positioning grooves 43 and the first positioning pins 44. Preferably, the top surface of the first positioning block 42 has two first positioning grooves 43, which can be used to position two stator lower modules of different specifications.

[0035] Furthermore, the second positioning seat 41 is provided with two positioning components 45, each including a second positioning pin 451 and a driving member 452 for driving the second positioning pin 451 to move up and down; the upper end of the second positioning pin 451 can move upward through the first positioning block 42. In this embodiment, the driving member 452 is preferably a cylinder. In use, the driving member 452 drives the second positioning pin 451 to move upward, so that the upper end of the second positioning pin 451 extends out of the lower stator module, which facilitates precise positioning of the upper stator module.

[0036] like Figure 5 As shown, the stator module positioning assembly 5 includes a third positioning seat 51 and a second positioning block 52 disposed on the third positioning seat 51. The top surface of the second positioning block 52 has one or more second positioning grooves 53 arranged coaxially.

[0037] Furthermore, two clearance grooves 55 are provided on the second positioning block 52, which are connected to each of the second positioning grooves 53, so as to facilitate the two second clamping components 7 to clamp the module on the stator.

[0038] In this motor stator assembly device, the top surface of the first slide 21 is also provided with a transfer platform 9 for placing the motor stator, and the transfer platform 9 is located at the end of the first slide 21 away from the second slide 22.

[0039] In the motor stator assembly device, the drive assembly includes a rack 8 parallel to the track 11, a gear meshing with the rack 8, and a motor that drives the gear to rotate; wherein the rack 8 is fixed relative to the frame 1, and the gear is rotatably mounted on the first slide 21 or the second slide 22.

[0040] like Figures 6 to 8 As shown, two first clamping assemblies 6 are located above two second clamping assemblies 7; the first clamping assemblies 6 and the second clamping assemblies 7 have similar structures, each including a gripper base 61, a gripper 62 connected to the gripper base 61, and a gripper drive 63 for driving the gripper base 61 to move linearly; wherein, the gripper base 61 is horizontally slidably connected to the lifting frame 12. In this embodiment, the gripper drive 63 is preferably an electric linear slide.

[0041] Furthermore, in the first clamping assembly 6, the gripper 62 has two first arc-shaped grooves 64 arranged vertically, which match the outer peripheral surface of the intermediate shaft. In the second clamping assembly 7, the gripper 62 has a second arc-shaped groove 65 that matches the outer peripheral surface of the upper module of the stator, and the second arc-shaped groove 65 can be formed by splicing two or more arc-shaped grooves.

[0042] In this motor stator assembly device, the lifting drive component 13 is preferably a hydraulic cylinder. To prevent the lifting frame 12 from shifting during its up-and-down movement, several guide posts and guide sleeves that slide with the guide posts can be provided on the frame 1, wherein the guide sleeves are installed on the lifting frame 12.

[0043] The main operating steps of the motor stator assembly device of this utility model are as follows:

[0044] The lower stator module positioning component 4, the intermediate shaft positioning component 3, and the upper stator module positioning component 5 are used to position the lower stator module, the intermediate shaft, and the upper stator module to be assembled, respectively.

[0045] The first slide 21 slides along the track 11, moving the intermediate shaft to the material handling position; the two first clamping assemblies 6 move downward to clamp the intermediate shaft.

[0046] The first slide 21 continues to slide along the track 11, moving the lower stator module to the material pick-up and drop-off position; the two first clamping assemblies 6 clamp the intermediate shaft and move it downward, assembling the intermediate shaft onto the lower stator module;

[0047] The second slide 22 slides along the track 11, moving the stator module to the material handling position; the two second clamping assemblies 7 move downward to clamp the stator module.

[0048] The first slide 21 slides along the track 11, causing the lower stator module to move back to the material pick-up and drop position; the two second clamping components 7 clamp the upper stator module and move it downward, assembling the upper stator module onto the lower stator module to form the motor stator; the two second clamping components 7 clamp the motor stator and move it upward.

[0049] The first slide 21 slides along the track 11, moving the transfer platform 9 to the material handling position; the two second clamping components 7 clamp the motor stator and move it downwards, placing the motor stator on the transfer platform 9.

[0050] This utility model discloses a motor stator assembly device. When placing the lower stator module, intermediate shaft, and upper stator module to be assembled, and when removing the assembled motor stator, there are no obstructions above the first slide 21 and the second slide 22, thus the working space is unrestricted and the loading and unloading of materials is very convenient. In addition, the motor stator assembly device uses the lower stator module positioning component 4, the intermediate shaft positioning component 3, and the upper stator module positioning component 5 to accurately position the lower stator module, intermediate shaft, and upper stator module to be assembled, respectively. By accurately clamping the two first clamping components 6 and the two second clamping components 7, and by accurately moving the first slide 21 and the second slide 22 into position, high-precision assembly of the motor stator can be ensured.
