[0013] Beneficial effects

[0014] This invention provides a brushless DC motor stator processing unloading device. Compared with the prior art, it has the following advantages:

[0015] 1. This brushless DC motor stator processing and unloading device uses a fixing component to fix the stator. The fixing component can fix stators of different sizes. The fixing component includes a hollow cylinder with four hollow cylinders evenly spaced on its surface. The hollow cylinder is slidably connected to a support frame at a sliding groove. When processing the motor stator, the iron core is sleeved onto the outside of the hollow cylinder.

[0022] The technical solutions of the present utility model 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 utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figures 1-4 The brushless DC motor stator processing unloading device offers two technical solutions:

[0024] The first embodiment includes a workbench 1 and a clamping assembly 2. A material handling mechanism is provided above the workbench 1. The material handling mechanism includes a switching assembly 4, four fixing assemblies 5 and a material unloading assembly 6.

[0025] The switching component 4 is used to switch the position of the stator, allowing the stator to sequentially enter the clamping position and the unloading position. The fixing component 5 is used to fix the stator, and the fixing component 5 can fix stators of different sizes. The unloading component 6 is used to unload the processed stator, and the unloading component 6 works in conjunction with the fixing component 5. The fixing component 5 includes a hollow cylinder 51, and four hollow cylinders 51 are evenly spaced on the surface of the hollow cylinder 51. The hollow cylinders 51 are slidably connected to a support frame 53 at a slide groove 52. The interior of the support frame 53 is evenly spaced... Four slide grooves 54 are provided, and sliders 55 are slidably connected to the inner surfaces of the four slide grooves 54. Inner support blocks 56 are fixedly connected to the top of the four sliders 55. A return spring 57 is fixedly connected between the inner wall of the slide groove 54 and the slider 55. A stepper motor 59 is fixedly connected to the bottom of the support frame 53. A disc 510 is fixedly connected to the output end of the support frame 53. Four arc-shaped push blocks 511 are fixedly connected at equal intervals along the circumference of the surface of the disc 510. A baffle 58 that cooperates with the arc-shaped push blocks 511 is fixedly connected to the inner side of the four inner support blocks 56.

[0026] When processing the motor stator, the iron core is sleeved on the outside of the hollow cylinder 51, and the iron core is fixed by the rotation of the arc-shaped push block 511 and the cooperation of the baffle 58. The inner support block 56 moves a different distance depending on the rotation angle of the arc-shaped push block 511, so that iron cores of different sizes can be fixed, which improves the convenience of processing the stator.

[0027] The second embodiment differs from the first embodiment in that: the switching component 4 includes a servo motor 41, which is fixedly connected to the top of the inner wall of the worktable 1. A drive shaft 42 is fixedly connected to the output end of the servo motor 41, and the drive shaft 42 passes through the worktable 1 and extends above it. A turntable 43 is fixedly connected to one end of the drive shaft 42 located above the worktable 1. Four fixing components 5 are equidistantly fixed to the top of the turntable 43. The unloading component 6 includes four through holes 61 equidistantly opened inside the turntable 43, and the four through holes 61 are connected to the hollow cylinder 51. The workbench 1 is connected to an electric push rod 62, which is fixedly connected to the top of the inner wall. The telescopic end of the electric push rod 62 is fixedly connected to a push rod 63. The top of the turntable 43 is fixedly connected to four brackets 64 at equal intervals via brackets 64. The positions of the four brackets 64 correspond to the positions of the fixed components 5. An infrared signal receiver 66 is embedded in the top of the workbench 1. The position of the infrared signal receiver 66 corresponds to the position of the electric push rod 62. A controller 3 is installed on the top of the workbench 1. The signals from the infrared signal generator 65 and the infrared signal receiver 66 are processed by the controller 3.

[0028] During stator processing, the electric push rod 62 and the support frame 53 work together to push the iron core out of the hollow cylinder 51. The infrared signal generator 65 and the infrared signal receiver 66 work together to ensure that the switching component 4 is accurately positioned and that the fixing component 5 and the unloading component 6 work together in coordination.

[0029] In use, the stator core is fitted onto the hollow cylinder 51. The stepper motor 59 is started to rotate the disc 510. The rotation of the disc 510 causes the arc-shaped push block 511 to contact the baffle 58, thereby causing the inner support block 56 to move. The inner support block 56 moves and internally supports and fixes the stator core fitted onto the hollow cylinder 51. Then, the servo motor 41 is started to rotate the turntable 43 to the bottom of the clamping assembly 2. The clamping assembly 2 is started to clamp the stator core. After clamping is completed, the servo motor 41 is started again to make the clamped stator core enter the position of the unloading assembly 6. When the infrared signal generator 65 and the infrared signal receiver 66 are aligned, the electric push rod 62 is started. At the same time, the stepper motor 59 rotates to reset the arc-shaped push block 511. The electric push rod 62 moves upward and pushes the support frame 53 to move up and down, thereby pushing the stator core to move upward. When the support frame 53 moves upward, the four inner support blocks 56 retract into the hollow cylinder 51.
