[0026] The present invention will be further described in detail below with reference to the accompanying drawings.

[0027] Identical parts are indicated by the same reference numerals. It should be noted that the terms "front," "rear," "left," "right," "up," and "down" used in the following description refer to directions in the accompanying drawings, while the terms "bottom surface," "top surface," "inner," and "outer" refer to directions toward or away from the geometric center of a specific part, respectively.

[0028] like Figures 1 to 2As shown, an automatic testing and pressing machine for an external rotor motor includes a workbench 1. A material conveying linear module 2 is provided on the surface of the workbench 1. Several sets of material conveying components 10 are slidably connected on the material conveying linear module 2. Several sets of workpiece placement components 20, several sets of testing components 30, and a material discharge and conveying component 40 are provided at one end of the material conveying component 10. The testing component 30 is connected to the workbench 1 through a testing bracket 3. A power supply component 50 is provided below it. A movable turntable 4 is provided between the material discharge and conveying component 40 and the testing component 30. Several sets of rotary components 60 are rotatably connected to the surface of the movable turntable 4. A snap ring pressing component 70 and a cotter pin pressing component 80 are provided on the periphery of the movable turntable 4. A rotary drive component 90 that meshes with the rotary component 60 is provided on one side of the cotter pin pressing component 80.

[0029] Workbench 1 provides support for the entire device. The external rotor motor, i.e., the material, enters the device from the previous process. Specifically, the material is placed on the workpiece placement assembly 20 at the feeding end. The conveying assembly 10 moves the material from the workpiece device assembly at the feeding end to the workpiece placement assembly 20 below the testing assembly 30. Each testing assembly 30 has a corresponding workpiece placement assembly 20 below it. At this time, the testing assembly 30 first presses the material on the workpiece placement assembly 20, and then the power supply assembly 50 energizes the material to test its electrical properties. After the test is completed, the conveying assembly 10 transports the material again so that it can enter the next process. It should be noted that two sets of waste collection assemblies 100 are set around the movable turntable 4. The two sets of waste collection assemblies 100 collect the defective products after the electrical testing and pressing processes, respectively. The structure of the waste collection assembly 100 will be described in detail in the next paragraph. The conveying assembly 10 transports the qualified products to the surface of the rotary assembly 60. The defective products are transported to the waste collection assembly 100. The movable turntable 4 is connected to the workbench 1 by rotation, so that each rotating component 60 on the movable turntable 4 can receive the material. Two types of pressing components are set on the periphery of the movable turntable 4. The two pressing components will be described separately below. When rotating to the vicinity of the station of the snap ring pressing assembly 70, the corresponding part in the snap ring pressing assembly 70 installs the snap ring onto the material; when rotating to the vicinity of the station of the cotter pin pressing assembly 80, the material is first pressed against the cotter pin. The assembly 80 abuts against the material, and then the rotary drive assembly 90 drives the rotary assembly 60 to rotate, so that the hole of the material corresponds to the cotter pin. The cotter pin pressing assembly 80 can install the cotter pin onto the material. After completing any of the above pressing processes, the movable turntable 4 rotates, so that the pressed material is rotated to the vicinity of the workstation of the discharge conveying assembly 40. The material conveying assembly 10 at the discharge end collects the material, placing qualified products on the discharge conveying assembly 40 and unqualified products on the waste collection assembly 100.

[0030] like Figure 10As shown, the specific structure of the waste collection assembly 100 includes a waste vertical cylinder 101, which is connected to the surface of the workbench 1 via a waste side plate 102. The waste vertical cylinder 101 is connected to a waste gripper cylinder 104 via a waste collection plate 103. The waste gripper cylinder 104 has two waste grippers, and a conveyor belt is located below it. This conveyor belt has a conventional structure and is driven by a motor, so it will not be described in detail. When in use, the waste vertical cylinder 101 raises the waste gripper cylinder 104 to a certain height, the conveying assembly 10 places the collected defective products onto the waste gripper, the waste vertical cylinder 101 drives the waste gripper cylinder 104 to descend, the waste gripper cylinder 104 releases the waste gripper, and the defective products fall onto the conveyor belt for transportation. This allows the defective products to be removed from the device. This assembly can collect defective products and reduce secondary damage to them.

[0031] The discharge conveyor component 40 is also a conventional conveyor belt structure, so it will not be described in detail.

[0032] like Figures 3 to 4 As shown, there are three sets of feeding components 10. The feeding end of the feeding linear module 2 is equipped with two sets of feeding components 10, and the discharging end is equipped with one set of feeding components 10. The feeding component 10 includes a feeding gripper cylinder 11 and a feeding slide 12 slidably connected to the feeding linear module 2. The feeding gripper cylinder 11 is equipped with two feeding grippers 13. The feeding gripper cylinder 11 is bolted to a first feeding plate 14. The feeding slide 12 is equipped with a feeding vertical cylinder 15. The first feeding plate 14 of the feeding end feeding component is bolted to a feeding horizontal cylinder 16. The feeding horizontal cylinder 16 is bolted to the feeding vertical cylinder 15 through a second feeding plate 17. The feeding gripper cylinder 11 of the feeding end feeding component is equipped with a feeding rotary cylinder 18. The first feeding plate 14 of the discharging end feeding component is bolted to the feeding vertical cylinder 15.

[0033] Three sets of feeding components 10 perform different functions. The first set of feeding components 10 at the inlet end transfers the material from the workpiece placement component 20 at the inlet end to the workpiece placement component 20 below the testing component 30. Specifically, the vertical feeding cylinder 15 descends to a specified height, the horizontal feeding cylinder 16 moves horizontally, and the feeding gripper cylinder 11 controls the feeding gripper 13 to clamp the material. After clamping, the feeding linear module 2 drives the feeding slide 12 to move. The second set of feeding components 10 at the inlet end also needs to move the material. The operation steps for moving the material are the same as those of the first set of feeding components 10 at the inlet end, but the second set of feeding components at the inlet end... The material feeding assembly 10 moves the material from the workpiece placement assembly 20 to the rotary assembly 60. Since the rotary assembly 60 needs to cooperate with the pressing assembly to complete the pressing, the second feeding end feeding assembly 10 is equipped with a feeding rotary cylinder 18 to rotate the material for easy pressing. The function of the discharging end feeding assembly 10 is to move the processed material on the rotary assembly 60 to the waste collection assembly 100 or the discharge transport assembly 40. Specifically, the feeding linear module 2 drives the feeding slide 12 to move to the vicinity of the rotary assembly 60, the feeding vertical cylinder 15 drives the feeding gripper cylinder 11 to move, and the feeding gripper 13 clamps the material. After clamping, the material is moved to the waste collection assembly 100 or the discharge transport assembly 40.

[0034] like Figure 5 As shown, the workpiece placement assembly 20 includes a placement rack 21, a loading and placement fixture 22 is provided on the placement rack 21, and a plurality of workpiece positioning blocks 23 are provided on the loading and placement fixture 22.

[0035] The workpiece placement assembly 20 can temporarily store materials placed in the previous process or cooperate with the test assembly 30 to complete the test. The placement rack 21 provides support and increases the placement height of the materials. The loading and placement fixture 22 and the workpiece positioning block 23 provide storage space for the materials and facilitate the rapid placement and positioning of the materials.

[0036] like Figure 5 As shown, the test assembly 30 includes a test lifting slide 31 that is slidably connected to the test bracket 3. A test pressing fixture 32 is provided at the bottom of the test lifting slide 31, and a test lifting connecting plate 33 is provided at the top of the slide. A test lifting cylinder 34 is provided on the test lifting connecting plate 33, and the test lifting cylinder 34 is connected to the test bracket 3 through a test lifting seat. like Figure 5 As shown, the power supply assembly 50 includes a power supply horizontal cylinder 51 mounted on the placement frame 21, a first power supply plate 52 bolted to the power supply horizontal cylinder 51, a power supply vertical cylinder 53 bolted to the first power supply plate 52, and a power supply fixture plate 54 mounted on the power supply vertical cylinder 53.

[0037] The test assembly 30 and the power supply assembly 50 work together to test the electrical properties of materials. Specifically, the test lifting cylinder 34 provides driving force to lower the test lifting connecting plate 33, and the corresponding test lifting slide 31 also lowers. The lowering of the test lifting slide 31 drives the test pressing fixture 32 to lower, and the test pressing fixture 32 presses the material on the loading fixture 22. At this time, the power supply horizontal cylinder 51 of the power supply assembly 50 starts to work, and drives the power supply vertical cylinder 53 to move through the first power supply plate 52. The power supply vertical cylinder 53 drives the power supply fixture plate 54 to rise and energize the material. After the test is completed, the test assembly 30 and the power supply assembly 50 are reset.

[0038] like Figure 6 As shown, the rotary assembly 60 includes a rotary shaft 61, a pressure-fitting fixture 62 is provided on the top of the rotary shaft 61, and a rotary gear 63 is provided on its bottom. The rotary shaft 61 is connected to the movable turntable 4 through a rotary bearing seat 64.

[0039] The material that has been rotated in the previous process can be stored on the pressing fixture 62. The rotating shaft 61 and rotating gear 63 and other components can cooperate with the cotter pin pressing assembly 80 to complete the pressing of the cotter pin.

[0040] like Figures 7 to 8 As shown, two vibrating feeders 5 are arranged around the movable turntable 4. Both vibrating feeders 5 are connected to the worktable 1 through a bracket. Two pressing and lifting assemblies 6 are also arranged around the movable turntable 4. The two pressing and lifting assemblies 6 are respectively connected to the snap ring pressing assembly 70 or the cotter pin pressing assembly 80.

[0041] The vibrating feeder 5 can transport the snap ring or cotter pin to the storage slot 703 of the snap ring pressing assembly 70 or the cotter pin guide fixture 811. The pressing lifting assembly 6 is connected to the snap ring pressing cylinder 710 of the snap ring pressing assembly 70 or the displacement connecting plate 808 of the cotter pin pressing assembly 80. The vibrating feeder 5 transports the snap ring or cotter pin to the snap ring pressing assembly 70 or the cotter pin pressing assembly 80. The pressing lifting assembly 6 can cooperate with the snap ring pressing assembly 70 or the cotter pin pressing assembly 80 to press the snap ring or cotter pin onto the material.

[0042] like Figure 7As shown, the snap ring pressing assembly 70 includes a storage cylinder 701, which is connected to the workbench 1 via a storage bracket. A storage fixture 702 is provided on the top of the storage cylinder 701, and a storage slot 703 is provided on the storage fixture 702. A snap ring conveying cylinder 704 is provided above the storage fixture 702. A snap ring linear module 706 is slidably connected to the snap ring conveying slide 705 via the snap ring conveying slide table 705. The snap ring linear module 706 is connected to the workbench 1 via a snap ring base frame 707. A conveying connecting plate 708 is provided on the snap ring conveying cylinder 704, and a snap ring conveying fixture 709 is provided on the conveying connecting plate 708. A snap ring pressing cylinder 710 is provided below the snap ring conveying fixture 709, and a snap ring pressing fixture 711 is provided on the snap ring pressing cylinder 710. A snap ring blocking fixture 712 is provided on the snap ring pressing fixture 711.

[0043] The vibrating feeder 5 transports the retaining ring to the storage slot 703. The storage cylinder 701 moves the storage fixture 702, positioning the storage slot 703 directly below the retaining ring conveying fixture 709. The retaining ring conveying cylinder 704 lowers the conveying connecting plate 708, allowing the retaining ring conveying fixture 709 to pick up the retaining ring. After picking up the retaining ring, the retaining ring conveying cylinder 704 resets. The retaining ring linear module 706 then drives the retaining ring conveying cylinder 709 via the retaining ring conveying slide 705. 4. The displacement position of the circlip conveying fixture 709 is such that it is directly above the circlip blocking fixture 712. The circlip conveying fixture 709 descends again, transporting the circlip into the circlip blocking fixture 712. The pressing and lifting assembly 6 drives the circlip pressing cylinder 710 to descend, so that the material on the pressing and placing fixture 62 and the circlip blocking fixture 712 are at the same height. Then, the circlip pressing cylinder 710 drives the circlip pressing fixture 711 to move, so that the circlip in the circlip blocking fixture 712 is pushed onto the material.

[0044] like Figure 8As shown, the cotter pin press-fit assembly 80 includes a cotter pin conveying cylinder 801, two cotter pin conveying grippers 802 on the cotter pin conveying cylinder 801, a cotter pin positioning fixture 803 below the two cotter pin conveying grippers 802, a vertical linear module 804 on the cotter pin conveying cylinder 801, a horizontal linear module 805 on the vertical linear module 804, the horizontal linear module 805 being connected to the worktable 1 via a cotter pin bracket 806, and a displacement device below the horizontal linear module 805. The cylinder 807 is equipped with a displacement connecting plate 808, a cotter pin press-fit cylinder 809 is equipped with a cotter pin pressing fixture 810 is equipped with a cotter pin pressing fixture 810, a cotter pin guide fixture 811 is equipped at the bottom of the cotter pin pressing fixture 810, cotter pin blocking fixtures 812 are equipped on both sides of the cotter pin guide fixture 811, a core-aligning fixture 813 is equipped at the top of the cotter pin guide fixture 811, and a press-fit groove 814 is provided on the cotter pin blocking fixture 812.

[0045] The vibrating feeder 5 transports the cotter pins to the cotter pin positioning fixture 803. At this time, the cotter pins are directly below the cotter pin conveying gripper 802. The vertical linear module 804 drives the cotter pin conveying cylinder 801 to descend, and the cotter pin conveying cylinder 801 drives the cotter pin conveying gripper 802 to clamp the cotter pins. The vertical linear module 804 resets, and the horizontal linear module 805 moves the vertical linear module 804 to directly above the displacement cylinder 807. The cotter pin conveying cylinder 801 descends again, transporting the cotter pin on the cotter pin conveying gripper 802 to the cotter pin pressing fixture 810. The cotter pin pressing cylinder 809 drives the cotter pin pressing fixture 810 to move, passing through the cotter pin blocking fixture 812, so that the cotter pin reaches the cotter pin guide fixture 811 and one side of the cotter pin contacts the core-aligning fixture 813. At this time, there is material on the pressing placement fixture 62, and the top of the material contacts the pressing groove 814.

[0046] like Figure 6 As shown, the rotary drive assembly 90 includes a drive motor 91, a drive gear 92 is provided on the output shaft of the drive motor 91, the drive gear 92 meshes with the rotary gear 63, the drive motor 91 is bolted to a drive seat, a plurality of guide shafts 93 are provided on the drive seat, guide seats are provided on the guide shafts 93, and a rotary slide 95 is bolted to the bottom of the guide seat, the rotary slide 95 is slidably connected to the worktable 1.

[0047] The function of the rotary drive assembly 90 is to drive the rotary assembly 60 to rotate, causing the material on the rotary assembly 60 to rotate. The hole of the material can be aligned with the cotter pin, allowing the cotter pin to be inserted into the hole of the material and completing the pressing of the material. Specifically, the rotary slide 95 slides, and correspondingly drives the guide seat, guide seat and drive seat to slide. As a result, the drive gear 92 can mesh with the rotary gear 63. The drive motor 91 causes the drive gear 92 to rotate, and the drive gear 92 drives the rotary gear 63 to rotate. Correspondingly, the rotary shaft 61 and the pressing fixture 62 rotate. After rotating a certain angle, the cotter pin pressing cylinder 809 generates driving force, causing the cotter pin pressing fixture 810 to drive the cotter pin to disengage from the cotter pin guide fixture 811 and pass through the core-aligning fixture 813 into the material.
