Traditional skew-slot rotor stacking processes typically rely on manual operation or semi-automated equipment, which is not only inefficient but also makes it difficult to guarantee stacking accuracy and consistency. This is especially true when handling rotor cores of different diameters, often requiring frequent tooling adjustments and consuming significant time and labor costs. Furthermore, inaccuracies in angle fine-tuning frequently lead to poor rotor core assembly quality, affecting the performance of the final product. Therefore, we propose a skew-slot rotor stacking fixture. Utility Model Content

[0028] Please see Figure 1-4 This utility model provides a technical solution:
[0029] A skewed rotor stacking fixture includes a worktable 1. Four support legs 2 are fixedly connected to the lower end of the worktable 1. A detection camera 3 is fixedly connected to the front upper end of the worktable 1. A bracket 4 is fixedly connected to the rear upper end of the worktable 1. A hydraulic rod 7 is fixedly connected to the lower end of the bracket 4. A stacking end plate 71 is fixedly connected to the output end of the hydraulic rod 7. A mounting frame 5 is fixedly connected to the front end of the bracket 4. A sliding groove 51 is opened at the front end of the mounting frame 5. An angle fine-tuning component 9 is slidably installed in the sliding groove 51. A positioning rod 6 is fixedly connected to the middle upper end of the worktable 1. Several rotor cores 61 are placed in the middle upper end of the worktable 1. Concentric adjustment components 8 are fixedly installed on both the left and right sides of the upper end of the worktable 1. The length of the mounting frame 5 is greater than the length of the positioning rod 6. The four support legs 2 are symmetrically distributed in pairs.
[0030] In this embodiment, the concentric adjustment assembly 8 includes a mounting plate 81. Support rods 82 are fixedly connected to both the front and rear ends of the mounting plate 81. Two first electric telescopic rods 83 are fixedly connected to one end of the mounting plate 81 near the rotor core 61. A connecting frame 84 is fixedly installed on the two first electric telescopic rods 83 near the rotor core 61. A slot 85 is opened on one end of the connecting frame 84 near the rotor core 61. A clip 86 is engaged in the slot 85. A gathering plate 87 is fixedly connected to one end of the clip 86 near the rotor core 61. The size of the clip 86 is adapted to the size of the slot 85. The length of the clip 86 is greater than the length of the connecting frame 84. The curvature of the gathering plate 87 is equal to the curvature of the rotor core 61. The mounting plate 81 and the two support rods 82 are both fixedly installed on the upper end of the workbench 1.
[0031] Through the above scheme: After the adjustment is completed, in order to ensure that all rotor cores 61 are at the same axis, two sets of mounting plates 81 are welded to the upper end of the workbench 1. The mounting plates 81 are supported by the support rods 82. The first electric telescopic rod 83 is activated. The output end of the first electric telescopic rod 83 drives the connecting frame 84 to move towards the rotor core 61. At the same time, the rotor core 61 is clamped by two sets of gathering plates 87. The gathering plates 87 are engaged with the slots 85 by the clips 86, which facilitates replacement and makes them suitable for rotor cores 61 of different diameters. The automated assisted clamping of the rotor core 61 improves the stacking efficiency.
[0032] In this embodiment, the angle fine-tuning component 9 includes a first motor 91. A threaded rod 92 is fixedly connected to the output end of the first motor 91. A slider 93 is fixedly connected to the outer surface of the threaded rod 92. Two second electric telescopic rods 94 are fixedly connected to the front end of the slider 93. A fixing plate 95 is fixedly installed on the front end of the two second electric telescopic rods 94. A driving roller 97 and a driven roller 98 are rotatably connected to the left and right parts of the upper end of the fixing plate 95, respectively. A second motor 96 is rotatably connected to the upper end of the driving roller 97. A friction belt 99 is slidably installed on the outer surfaces of the driving roller 97 and the driven roller 98. The size of the slider 93 is adapted to the size of the groove 51. The width of the friction belt 99 is smaller than the width of the rotor core 61.
[0033] The above scheme works as follows: When it is necessary to adjust the stacking angle of the rotor core 61, the first motor 91 is started. The output end of the first motor 91 drives the threaded rod 92 to rotate. The threaded rod 92 drives the slider 93 connected to its outer surface to slide in the slide groove 51, thereby adjusting the height position of the friction belt 99. The second motor 96 is started. The output end of the second motor 96 drives the active roller 97 to rotate. The active roller 97 and the driven roller 98 simultaneously drive the friction belt 99 to rotate. The second electric telescopic rod 94 is started to bring the friction belt 99 close to the rotor core 61, so as to fine-tune the angle of the rotor core 61, improve the stacking assembly accuracy of the rotor core 61, and improve the processing quality of the rotor core 61.
[0034] It should be noted that this utility model is a skewed rotor stacking fixture. During use, several rotor cores 61 are first placed on the workbench 1 and preliminarily positioned using the positioning rod 6. The inspection camera 3 takes pictures of the rotor core 61 assembly for diagnostic purposes and issues relevant adjustment commands. When the stacking angle of the rotor core 61 needs to be adjusted, the first motor 91 is started. The output end of the first motor 91 drives the threaded rod 92 to rotate. The threaded rod 92 drives the slider 93, which is threaded to its outer surface, to slide within the groove 51, thereby adjusting the height of the friction belt 99. The second motor 96 is then started. The output end of the second motor 96 drives the driving roller 97 to rotate. The driving roller 97 and the driven roller 98 simultaneously drive the friction belt 99 to rotate. The second electric telescopic rod 94 is then activated to bring the friction belt 99 close to the rotor core 61, thus adjusting the height of the rotor core 61. The angle of the workbench 1 is finely adjusted to improve the stacking accuracy of the rotor core 61 and the processing quality of the rotor core 61. After the adjustment, in order to ensure that all rotor cores 61 are in the same axis, two sets of mounting plates 81 are welded to the upper end of the workbench 1. The mounting plates 81 are supported by the support rod 82. The first electric telescopic rod 83 is activated. The output end of the first electric telescopic rod 83 drives the connecting frame 84 to move towards the rotor core 61. At the same time, the rotor core 61 is clamped by two sets of gathering plates 87. The gathering plates 87 are engaged with the slots 85 by the clips 86 to facilitate replacement and make them suitable for rotor cores 61 of different diameters. The automatic assisted clamping of the rotor core 61 improves the stacking efficiency. The hydraulic rod 7 is activated. The output end of the hydraulic rod 7 drives the stacking end plate 71 to press down and press the rotor core 61, completing the stacking operation.
