[0018] 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.

[0019] Example:

[0020] Please see Figure 1-4A PIN feeding fixture for cradle motor gear assembly in automobiles includes an upper guide rail 1, a lower guide rail 2, a first translation device 3, and a second translation device 4. A feeding seat plate 5 and an implantation seat plate 6 are fixedly connected to the upper guide rail 1. A first slide plate 7 is slidably connected to the upper guide rail 1. The moving platform of the first translation device 3 is fixedly connected to the first slide plate 7. A second slide plate 8 is slidably connected inside the lower guide rail 2. The moving platform of the second translation device 4 is fixedly connected to the second slide plate 8. A carrier 12 is detachably connected to the second slide plate 8. A first feeding pipe 10 is provided on the feeding seat plate 5. A plurality of second feeding pipes 11 are provided on the feeding seat plate 5 around the first feeding pipe 10. A lifting device 9 is provided on the implantation seat plate 6. A first ejector pin 901 and a second ejector pin 902 are fixedly connected to the lifting platform of the lifting device 9.

[0021] The first translation device 3, the second translation device 4, and the lifting device 9 are all cylinders. The upper guide rail 1 and the lower guide rail 2 are fixedly connected. The upper guide rail 1 can guide and limit the translation and sliding of the first slide plate 7, and the lower guide rail 2 can guide and limit the translation and sliding of the second slide plate 8. The cross-section of the upper guide rail 1 and the lower guide rail 2 are both C-shaped. The second translation device 4 is detachably connected to the lower guide rail 2. The carrier 12 and the second translation device 4 can be quickly disassembled and replaced according to the material loading needs.

[0022] The first feeding tube 10 and the second feeding tube 11 are fixedly connected to the feeding base plate 5. The first feeding tube 10 and the second feeding tube 11 are vertically arranged on the feeding base plate 5, which can guide the vertical feeding of the PIN pin. Multiple second feeding tubes 11 are distributed in a ring array along the first feeding tube 10.

[0023] The first ejector pin 901 and the second ejector pin 902 are slidably connected to the implantation base plate 6, and the implantation base plate 6 can guide the ejection action of the first ejector pin 901 and the second ejector pin 902.

[0024] The first slide plate 7 is provided with a material hole 701 corresponding to the first feeding tube 10 and the second feeding tube 11. The material hole 701 can collect the PIN pins at the first feeding tube 10 and the second feeding tube 11.

[0025] The carrier 12 is provided with a first positioning hole 1201 and a second positioning hole 1202. The first positioning hole 1201 is used to position and place the fine pin and the gear workpiece, and the second positioning hole 1202 is used to position and place the coarse pin.

[0026] The working principle of this utility model is as follows: When in use, the piston rod of the first translation device 3 is in the retracted state. At this time, the material hole 701 on the first slide plate 7 is located directly below the first feeding pipe 10 and the second feeding pipe 11. The fine PIN and the coarse PIN are fed into the material hole along the first feeding pipe 10 and the second feeding pipe 11, respectively. The piston rod of the second translation device 4 extends, and the second slide plate 8 slides to make the carrier 12 slide directly below the first ejector pin 901 and the second ejector pin 902. Then, the piston rod of the first translation device 3 extends, the first slide plate 7 slides, and the coarse PIN and the fine PIN in the material hole will also be moved to the first ejector pin 901. Directly below pin 901 and pin 902, the piston rod of lifting device 9 extends, and pins 901 and 902 push the coarse pin and fine pin in material hole 701 from the first slide plate 7 into the second positioning hole 1202 and the first positioning hole 1201 respectively. The first positioning hole 1201 is composed of a large hole and a small hole on the same axis. The small hole is used to position the fine pin, and the large hole is used to position the gear workpiece. After the coarse pin and fine pin are positioned and loaded, the first translation device 3 and the second translation device 4 are reset, and the gear is placed along the coarse pin, the fine pin and the first positioning hole 1201.
