[0002] Cylindrical pin machining refers to the manufacturing and processing of cylindrical pins to fulfill their positioning, connection, or fixing functions in mechanical assembly. Cylindrical pins are commonly used in mechanical structures as positioning elements, and can also be used for connection, overload shearing connections in release and safety devices, etc. The machining process involves multiple steps, including blanking, forming, and heat treatment, to ensure that their dimensional accuracy, geometry, and surface finish meet requirements.

Different specifications of cylindrical pins (such as varying lengths) require different feeding mechanisms or adjustments to complex mechanical structures, which is cumbersome and affects production efficiency. Therefore, we propose a continuous feeding device for cylindrical pin processing to solve the above problems. Utility Model Content

[0022] Depend on Figures 1-4 As shown, a continuous feeding device for processing cylindrical pins is disclosed, including a material frame 1. The inside of the material frame 1 is provided with an inclined guide surface to ensure that the cylindrical pin can slide to the feeding area by its own weight. A support plate 2 is fixedly connected inside the material frame 1. A circular frame 3 is fixedly connected to the top of the support plate 2. A motor 4 is fixedly connected inside the circular frame 3. Multiple heat dissipation holes are opened on the outer wall of the circular frame 3. A circular hole is opened on the outer wall of the support plate 2. The inner wall of the circular hole is rotatably connected to the outer wall of the output shaft of the motor 4.

[0023] A drive shaft 5 is fixedly connected to the bottom of the output shaft of motor 4. Multiple triangular stirring blades 6 are fixedly connected to the bottom outer wall of the drive shaft 5. The multiple triangular stirring blades 6 rotate through the drive shaft 5 to prevent multiple cylindrical pins from accumulating at the top of the feed pipe 10. A vertical shaft 7 is rotatably connected to the bottom of the support plate 2. A through hole is opened at the bottom of the material frame 1. The inner wall of the through hole is rotatably connected to the outer wall of the vertical shaft 7. Two deep groove ball bearings are fixedly fitted on the outer wall of the vertical shaft 7. The outer rings of the two deep groove ball bearings are fixedly connected to the bottom of the material frame 1 and the support plate 2, respectively. The two deep groove ball bearings provide sufficient vertical support force.

[0024] A driven gear 8 is fixedly sleeved on the outer wall of the vertical shaft 7, and a main gear 9 is fixedly sleeved on the outer wall of the transmission shaft 5. The main gear 9 and the driven gear 8 are meshed and connected. The transmission shaft 5 rotates through the meshing relationship between the main gear 9 and the driven gear 8. A feed pipe 10 is fixedly connected to the bottom of the material frame 1. A first material distribution plate 11 is fixedly sleeved on the outer wall of the vertical shaft 7. The top of the first material distribution plate 11 is in contact with the bottom of the feed pipe 10.

[0025] The outer wall of the vertical shaft 7 is provided with a feeding assembly, which includes two locking caps 14. A threaded rod 12 is fixedly connected to the bottom of the vertical shaft 7. A second distribution plate 13 is slidably sleeved on the outer wall of the threaded rod 12. The second distribution plate 13 moves up and down along the threaded rod 12. The outer wall of the threaded rod 12 is threadedly connected to the inner wall of the two locking caps 14. One end of each of the two locking caps 14 is pressed against the outer wall of the second distribution plate 13. The outer walls of the first distribution plate 11 and the second distribution plate 13 are both provided with arc-shaped grooves.

[0026] Working principle: During use, multiple cylindrical pins are placed on the inner wall of the material frame 1. The cylindrical pins move towards the top of the feed pipe 10 via the inclined surface inside the material frame 1. As the motor 4 slowly rotates, it drives the transmission shaft 5 to rotate. The rotation of the transmission shaft 5 drives multiple triangular stirring blades 6 to rotate, which in turn disperses the cylindrical pins, preventing blockage. The top of the feed pipe 10 is tapered to allow one end of the cylindrical pin to slide into the top of the feed pipe 10. Simultaneously, the diameter of the feed pipe 10 is slightly larger than the diameter of the cylindrical pin, ensuring that the cylindrical pin moves vertically downwards along the feed pipe 10 and falls onto the top of the first distribution plate 11. Furthermore, the rotation of the transmission shaft 5 drives the main gear 9... The main gear 9 rotates, driving the driven gear 8 to rotate, which in turn drives the vertical shaft 7 to rotate. The vertical shaft 7 then drives the first and second distribution discs 11 and 13 to rotate. Since the outer walls of the first and second distribution discs 11 and 13 are provided with arc-shaped grooves, and the two arc-shaped grooves are staggered, the first and second distribution discs 11 and 13 intermittently feed multiple cylindrical pins during rotation, causing the cylindrical pins to fall into the processing equipment below. At the same time, the two locking caps 14 can be rotated to release the position fixation of the second distribution disc 13, and the second distribution disc 13 can be moved up and down along the threaded rod 12 to adapt to the cylindrical pins of different lengths.

[0027] It should be noted that when actually put into use, an existing PLC controller can be added. The PLC controller is electrically connected to motor 4 to facilitate the control of the overall operation.

The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art.

Furthermore, the structure and principle of the components known to those skilled in the art can be learned by those skilled in the art through technical manuals or conventional experimental methods.
