Description

Technical Field

[0001] This utility model relates to the field of pin processing technology, specifically a feeding rack for pin processing. Background Technology

[0002] A pin is a standardized fastener that can provide a static connection or allow relative movement between the pin and the connected parts. It is primarily used at the hinge joints of two parts to form a hinge connection. Pins are typically locked with cotter pins, ensuring reliable operation and easy disassembly. During pin processing, a loading structure is used to load the pins to the processing station; this loading rack is used for this purpose.

[0003] A search revealed a Chinese patent publication number: CN220641312U, which provides a feeding rack for pin processing. This feeding rack includes a top platform, a motor mounted on the bottom left end of the top platform, drive shafts mounted on the inner sides of both the left and right ends of the top platform, a conveyor belt mounted on the end side of the drive shaft, a belt opening on the end wall of the conveyor belt, a partition belt placed on the end side of the belt opening, a bottom platform mounted on the bottom of the top platform, a fan mounted on the bottom end of the bottom platform, and an air cavity formed inside the bottom end of the bottom platform.

[0004] Although the aforementioned patent can clean the pin by blowing air, the device still has the following problems: during use, the device relies solely on airflow, which cannot effectively remove highly adhesive metal shavings, resulting in poor cleaning performance and potentially affecting subsequent processing of the pin. To address these issues, technological innovation is needed based on the existing device. Utility Model Content

[0021] Please see Figure 1-4 This utility model provides a technical solution: a feeding rack for processing pins, including a conveyor body 1. The conveyor body 1 is an existing structure and will not be described in detail here. The conveyor body 1 can convey pins via a conveyor belt. A support plate 2 is fixedly connected to the conveyor body 1 and is set on the conveyor belt of the conveyor body 1. A support block 3 is fixedly connected to the top of the support plate 2. A groove 4 is formed on the top of the support block 3. The groove 4 has a V-shaped cross-section and can hold the pin inside. Two fixing plates 5 are fixedly connected to the conveyor body 1. A connecting frame 6 is fixedly connected between the two fixing plates 5. The connecting frame 6 has an I-shaped cross-section. A hydraulic press 13 is fixedly connected to the bottom of the connecting frame 6. The hydraulic press 13 is an existing structure and will not be explained in detail here. The output end of the hydraulic press 13 slides through the interior of the connecting frame 6 and extends to the exterior of the connecting frame 6. The output end of the hydraulic press 13 is fixedly connected to... The top plate 7 has a support positioning plate 11 and a functional plate 12 fixedly connected to its bottom. The functional plate 12 has a hollow internal structure. A motor 14 is fixedly connected to one side of the support positioning plate 11. The motor 14 is an existing structure and will not be explained in detail here. The output end of the motor 14 rotates through the interior of the support positioning plate 11 and extends to the exterior of the support positioning plate 11. A cleaning roller 15 is fixedly connected to the output end of the motor 14. The cleaning roller 15 is located between the support positioning plate 11 and the functional plate 12. The cleaning roller 15 has a hollow internal structure. A brush 18 is provided on the outer surface of the cleaning roller 15. By rotating the cleaning roller 15, the cleaning roller 15 can clean the impurities on the pin shaft surface through the brush 18. An auxiliary blowing cleaning device is provided on the top plate 7. The hydraulic press 13 drives the top plate 7 to move up and down, which can adjust the distance between the cleaning roller 15 and the pin shaft and make the device operate more smoothly.

[0022] The operator starts the motor 14 through an external control device. The motor 14 drives the cleaning roller 15 to rotate. Through the rotation of the cleaning roller 15, the cleaning roller 15 can clean the impurities on the surface of the pin shaft through the brush 18. At the same time, the rotation direction of the cleaning roller 15 is opposite to the forward direction of the pin shaft. When the pin shaft enters the cleaning area, the counter-rotating cleaning roller 15 will first contact the upper side of the pin shaft. At the same time, the brush 1818 applies a frictional force to the pin shaft. This force generates a torque relative to the two contact points (fulcrums) between the pin shaft and the tray 4. This force will push the pin shaft forward. In conjunction with the force of the conveyor belt of the conveyor body 1, under the action of the torque, the pin shaft will naturally and smoothly rotate around its own axis in the tray 4. At the same time, under the combined action of the axial component force and the frictional force of the conveyor belt of the conveyor body 1, the pin shaft continues to move forward.

[0023] Ultimately, the pin shaft undergoes a combined motion of "rotation" and "revolution" (forward movement) as it passes under the brush roller 18. The cleaning roller 15 acts like a "hand," pushing it forward while continuously rolling it, thus ensuring that its entire cylindrical outer surface is thoroughly cleaned.

[0024] The auxiliary air-blowing cleaning device includes a blower 8, the surface of which is fixedly connected to the top of the top plate 7. The blower 8 is an existing structure and will not be explained in detail here. An air supply pipe 9 is fixedly connected to the exhaust end of the blower 8. The end of the air supply pipe 9 away from the blower 8 passes through the interior of the top plate 7 and is fixedly connected to the interior of the functional plate 12, allowing air from the external environment to enter the interior of the functional plate 12. A filter screen is installed on the air inlet end of the blower 8 to filter the air from the external environment. A rotating shaft 16 is fixedly connected to the end of the cleaning roller 15 near the functional plate 12, allowing it to rotate... The surface of shaft 16 is rotatably connected to the interior of functional plate 12. The interior of rotating shaft 16 is connected to the interior of cleaning roller 15. The interior of functional plate 12 is connected to the interior of rotating shaft 16, so that the gas inside functional plate 12 can enter the interior of cleaning roller 15 more smoothly through rotating shaft 16. Air blowing hole 17 is provided inside cleaning roller 15. Through air blowing hole 17, the gas inside cleaning roller 15 can be discharged and the gas can blow clean the surface of pin. The combined action of brush 18 cleaning and air blowing cleaning makes the pin cleaner more thorough.

[0025] The bottom of the top plate 7 is fixedly connected to a limiting plate 10, the surface of the limiting plate 10 is slidably connected to the inside of the connecting frame 6, and the surfaces of the supporting positioning plate 11 and the functional plate 12 are slidably connected to the inside of the connecting frame 6.

[0026] Working Principle: For this type of pin processing loading rack, the operator first places the pin inside the tray 4, then starts the conveyor body 1. The conveyor body 1 moves the pin via the conveyor belt. The operator starts the motor 14 via an external control device. The motor 14 drives the cleaning roller 15 to rotate. Through the rotation of the cleaning roller 15, the brush 18 cleans the impurities on the surface of the pin. At the same time, the rotation direction of the cleaning roller 15 is opposite to the forward direction of the pin. When the pin enters the cleaning zone, the reverse rotation... The rotating cleaning roller 15 will first contact the upper side of the pin, and at the same time the brush 1818 will apply a frictional force to the pin. This force will generate a torque relative to the two contact points (fulcrums) between the pin and the tray 4. This force will push the pin forward. In conjunction with the force of the conveyor belt of the conveyor body 1, under the action of the torque, the pin will naturally and smoothly rotate around its own axis in the tray 4. At the same time, under the combined action of the axial component force and the frictional force of the conveyor belt of the conveyor body 1, the pin will continue to move forward.

[0027] Ultimately, as the pin passes under the brush roller 18, it undergoes a combined motion of "rotation" and "revolution" (forward movement). The cleaning roller 15 acts like a "hand," pushing it forward while continuously rolling it, thus ensuring that its entire cylindrical outer surface is thoroughly cleaned. The air is expelled through the air hole 17, allowing the air to clean the surface of the pin. The combined effect of the brush 18 cleaning and the air cleaning makes the pin cleaner even more thoroughly.

[0028] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
