[0004] The aforementioned utility model requires manual unloading after each product processing, followed by oiling. This increases the number of steps in motor stator processing, affecting the processing efficiency of the motor stator. Furthermore, the efficiency of manual unloading after each processing step is low, impacting the automated operation of the equipment.

[0005] Therefore, it is necessary to design an electric vehicle motor stator oiling device to solve the above problems. Utility Model Content

[0006] The purpose of this invention is to address the shortcomings of existing technologies by proposing an electric vehicle motor stator oiling device. This device not only enables rapid unloading of processed products, but also utilizes the motor stator to roll on wool felt during unloading, thereby uniformly oiling the motor stator and greatly improving the processing efficiency of the motor stator.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] An electric vehicle motor stator oiling device includes a frame, a worktable fixedly connected to the upper end of the frame, two support rods fixedly connected to the upper end of the worktable, a transverse slide rail fixedly connected to the upper ends of the two support rods, a mechanical gripper slidably connected to the front side of the transverse slide rail, a flipping assembly provided on the worktable, a support frame provided on the front side of the frame, a connecting plate fixedly connected to the adjacent side of the support frame and the frame, a product chute fixedly connected to the upper end of the support frame, wool felt installed in the inner bottom of the product chute, and a vertical plate fixedly connected to the front side of the product chute.

[0013] Preferably, the lower end of the support frame is fixedly connected to multiple fixing plates, and multiple expansion screws are installed on each of the multiple fixing plates.

[0014] Compared with existing technologies, the advantages of this device are:

[0015] 1. Compared with existing technologies, this technology has achieved an automated oiling process, avoiding the need for manual unloading and separate oiling after product processing, which is required in existing technologies. This reduces the number of processing steps in motor stator manufacturing, effectively improves the overall processing efficiency of motor stator, and makes the entire production process smoother and more efficient, better meeting the needs of large-scale production.

[0016] 2. Compared with existing technologies, the equipment is equipped with a flipping component and a pushing component, which can flexibly operate the stator, facilitate precise oiling and subsequent transfer steps, further improve the automation level of the equipment, reduce manual intervention, reduce labor costs, reduce errors that may be caused by manual operation, and improve the stability of product quality.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] Reference Figures 1-4An electric vehicle motor stator oiling device includes a frame 1. A worktable is fixedly connected to the upper end of the frame 1. Two support rods 2 are fixedly connected to the upper end of the worktable. A transverse slide rail 3 is fixedly connected to the upper end of the two support rods 2. A mechanical gripper 4 is slidably connected to the front side of the transverse slide rail 3. The operation of the transverse slide rail 3 and the mechanical gripper 4 is in the prior art. After the bushing and rotor are welded, the mechanical gripper 4 can move the stator above the flipping tray 14. Then, the mechanical gripper 4 releases its grip, and under the action of gravity... The stator is placed on the flipping tray 14. A flipping assembly is provided on the worktable. A support frame 6 is provided on the front side of the frame 1. A connecting plate is fixedly connected to the adjacent side of the support frame 6 and the adjacent side of the frame 1. A product slide 9 is fixedly connected to the upper end of the support frame 6. A wool felt 16 is installed at the bottom of the inner side of the product slide 9. The wool felt 16 absorbs lubricating oil. The product slide 9 is inclined so that the stator can be evenly coated with oil when it rolls in the product slide 9. A vertical plate 11 is fixedly connected to the front side of the product slide 9.

[0025] The flipping assembly includes a side-flipping cylinder 12 mounted on the upper part of the workbench. A connector 13 is fixedly connected to the rotating end of the side-flipping cylinder 12. A flipping tray 14 is fixedly connected to the connector 13. The flipping tray 14 is L-shaped and is equipped with a pushing assembly. The pushing assembly includes a dual-axis cylinder 15 mounted on the flipping tray 14. A push plate 17 is fixedly connected to the telescopic end of the dual-axis cylinder 15. When the flipping tray 14 rotates, the stator can be rotated to a vertical position, and then the stator is pushed into the product slide 9 by the push plate 17.

[0026] Among them, two guide plates 10 are fixedly connected to the upper end of the product slide 9, and inclined plates 5 are fixedly connected to the rear side of each of the two guide plates 10. A buffer pad 18 is fixedly connected to the rear side of the vertical plate 11 to buffer the stator and prevent the stator from being damaged.

[0027] The lower end of the support frame 6 is fixedly connected to multiple fixing plates 7, and multiple expansion screws 8 are installed on each fixing plate 7 to stably fix the support frame 6 to the ground.

[0028] The functional principle of this utility model can be explained by the following operation: After the rotor bushing is welded, the mechanical gripper 4 is controlled to clamp the motor stator and move it to the upper end of the flipping tray 14. The mechanical gripper 4 is then controlled to release the clamp on the motor stator. At this time, under the action of gravity, the motor stator will fall onto the flipping tray 14.

[0029] The operator controls the side tilting cylinder 12 to rotate the tilting tray 14 and the motor stator to rotate 90 degrees, so that the motor stator rotates to a vertical position. The operator then controls the dual-axis cylinder 15 to push the stator forward using the push plate 17, so that the motor stator enters the product slide 9.

[0030] Because the product slide 9 is inclined downwards, the motor stator will roll forward under the action of gravity. Since the wool felt 16 has absorbed lubricating oil, the lubricating oil will be evenly applied to the motor stator as it rolls forward.

[0031] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
