[0002] This is primarily due to the stringent quality requirements of modern industry, especially in high-end manufacturing sectors such as aerospace, automotive, and precision instruments. These sectors have extremely high demands for the precision, surface quality, and consistency of fasteners, and the presence of burrs directly affects the assembly performance, sealing performance, and overall aesthetics of fasteners. High-precision fasteners require strict control over the processing accuracy of each step in the manufacturing process. Burrs, as a common defect in the processing, although small in size, often have a significant impact on the dimensional accuracy of fasteners. Especially in precision assembly, even tiny burrs can lead to assembly difficulties and inadequate sealing, thus affecting the overall performance of the product. The surface quality of fasteners directly affects their corrosion resistance, wear resistance, and aesthetic appearance. The presence of burrs will damage the surface finish of the fastener, increase surface roughness, and reduce its service life. Furthermore, in high-end manufacturing, fasteners often require surface treatment processes such as electroplating and spraying; the presence of burrs will affect the effectiveness of these processes and reduce the overall quality of the product. With the continuous development of industrial automation, the production of high-precision fasteners is also gradually shifting towards automation and intelligence. Traditional deburring methods, such as manual grinding and abrasive wheel grinding, are not only inefficient but also fail to guarantee consistent processing quality. Therefore, there is a need to develop high-precision deburring and grinding devices for fastener processing to achieve automated, efficient, and precise deburring. In summary, a high-precision deburring and grinding device for fastener processing is proposed to address these issues. Utility Model Content

Detailed Implementation
[0016] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.
[0017] like Figure 1 , Figure 2 and Figure 3 As shown, a high-precision fastener processing deburring and grinding device includes a processing base 1, a processing frame 2 on the processing base 1, and a fastener supply component and a grinding component on the processing frame 2. The fastener supply component includes a supply hopper 3, a slide rail 4, a rotating push rod 5, a hinge frame 6, and a stop plate 7. The supply hopper 3 is located on the processing frame 2, the hinge frame 6 is located on the supply hopper 3, the rotating push rod 5 is located on the hinge frame 6, the stop plate 7 is located at the end of the rotating push rod 5, the slide rail 4 is located on the bottom surface of the supply hopper 3, and the grinding component is located in the middle of the processing frame 2. In practice, the processing base 1 provides a stable support platform to ensure the stability and precision of the entire grinding device during operation, supports the processing frame 2 and all other components, and ensures their smooth operation. The processing frame 2 is used to install and adjust the fastener supply component and the grinding component. The supply hopper 3 on the fastener supply component facilitates the storage and automatic supply of fasteners to be processed, reducing manual intervention. The fasteners to be processed are stored and guided to the grinding area through the slide rail 4. The slide rail 4 ensures that the fasteners slide smoothly to the grinding position and guides the fasteners from the supply hopper 3 to the grinding component, ensuring continuous and stable feeding. Through the reciprocating motion of the rotating push rod 5, in conjunction with the abutment plate 7, the fasteners are pushed one by one to the grinding position, ensuring that the grinding process is continuous. The grinding component includes an active grinding wheel 8, a grinding spindle 9, a grinding auxiliary wheel 10, and an auxiliary grinding shaft 11. The active grinding wheel 8 is mounted on the grinding spindle 9, which is mounted on the processing base 1 via a first rotating seat 12. The auxiliary grinding shaft 11 is perpendicular to the grinding spindle 9 and does not intersect with it. It is mounted above the processing frame 2 via a second rotating seat 13. The grinding auxiliary wheel 10 is mounted on the auxiliary grinding shaft 11, and the grinding auxiliary wheel 10 is connected to the drive component via a rotating gear 14. One side of the active grinding wheel 8 abuts against the drive roller 15. In practice, the active grinding wheel 8 contacts the surface of the fastener through high-speed rotation and uses grinding force to remove burrs and uneven parts from the surface of the fastener. The grinding spindle 9 provides support and rotational power for the active grinding wheel 8, ensuring a stable axis and low vibration during high-speed rotation. The grinding auxiliary wheel 10 works in conjunction with the active grinding wheel 8 to grind the fastener from different angles, ensuring uniform and thorough grinding, helping to balance the stress during the grinding process, and reducing stress concentration caused by grinding in one direction.
[0018] like Figure 3As shown, based on the above method, the driving component further includes a drive motor 16, a first belt 17, a second belt 18, a first rotating wheel 19, and a second rotating wheel 20. The drive motor 16 is mounted on the processing base 1. The drive motor 16 is connected to the first rotating wheel 19 via the first belt 17. The second rotating wheel 20 is connected to the first rotating wheel 19 via the second belt 18. The first rotating wheel 19 is sleeved on one end of the drive roller 15. The second rotating wheel 20 is rotatably mounted on the processing frame 2. The second rotating wheel 20 is connected to the reducer 22 via the first rotating shaft 21. The reducer 22 is connected to the second rotating shaft 23. A drive gear 24 is mounted on the second rotating shaft 23. The drive gear 24 meshes with the rotating gear 14. In practice, the drive motor 16 serves as the power source for the entire drive system. The drive motor 16 generates power through rotation. The drive motor 16 is connected to the first rotating wheel 19 via the first belt 17 to achieve initial power transmission. The first rotating wheel 19 receives power from the first belt 17 and transmits it to the connected drive roller 15. The first rotating wheel 19 is sleeved on one end of the drive roller 15 to ensure direct and effective power transmission. The second belt 18 and the second rotating wheel 20 form a branch path for power transmission, used to transmit part of the power to the reducer 22, thereby driving the rotation of the grinding auxiliary wheel 10. The reducer 22 reduces the speed and increases the torque, ensuring that the grinding auxiliary wheel 10 works in a low-speed, high-torque state, thereby improving the grinding effect and stability. The reducer 22 is connected to the drive gear 24 through the second rotating shaft 23, transmitting the reduced power to the drive gear 24, and transmitting the power output by the reducer 22 to the grinding auxiliary wheel 10, driving it to rotate.
[0019] like Figure 1 As shown, based on the above method, a dust collection box 25 is further provided under the processing rack 2. The dust collection box 25 effectively collects the dust and debris generated during the grinding process, keeps the working environment clean, prevents dust and debris from flying, protects the working environment and personnel health, and facilitates subsequent cleaning and treatment.
[0020] like Figure 1 As shown, based on the above method, a sliding rail 26 is further provided between the processing base 1 and the processing frame 2. The processing frame 2 slides parallel to the processing base 1 via the sliding rail 26. A push handle 27 is provided on one side of the processing frame 2. In practice, the sliding rail 26 allows the processing frame 2 to slide parallel to the processing base 1. This design allows the grinding sub-rollers 10 on the processing frame 2 to be flexibly adjusted to adapt to the processing needs of fasteners of different sizes and positions. The design of the push handle 27 allows the operator to easily move the processing frame 2. When processing multiple fasteners, continuous operation can be achieved by quickly adjusting the position of the processing frame 2.
[0021] like Figure 4As shown, based on the above method, a fastener discharge slide 28 is further provided on one side of the grinding auxiliary wheel 10. The fastener discharge slide 28 ensures that the ground fasteners can smoothly leave the grinding area, avoid blockage, guide the ground fasteners out of the grinding area, and collect them into a designated container for subsequent processing and packaging.
[0022] In the specific working process of this novel high-precision fastener processing deburring and grinding device, the fasteners to be processed are placed into the feed hopper 3, which stores and initially sorts the fasteners. The processing frame 2 is installed and the positions of the fastener supply component and the grinding component are adjusted. The fasteners slide down into the slide rail 4 in the feed hopper 3 under gravity. The slide rail 4 guides the fasteners smoothly down to the grinding position. The rotating push rod 5, in its reciprocating motion, pushes the fasteners one by one to the grinding position through the abutment plate 7, ensuring that the grinding process is continuous. The drive motor 16 starts and transmits power to the first rotating wheel 19 through the first belt 17, thereby driving the drive roller 15 to rotate. At the same time, the second belt 18 and the second rotating wheel 20 transmit part of the power to the reducer 22. The reducer 22 reduces the speed and increases the torque, transmitting power to the grinding auxiliary wheel 10 through the second rotating shaft 23 and the drive gear 24, causing it to rotate. The active grinding wheel 8 contacts the surface of the fastener in high-speed rotation, using grinding force to remove burrs and uneven parts from the surface of the fastener. The grinding auxiliary wheel 10 works in conjunction with the active grinding wheel 8 to grind the fasteners from different angles, ensuring uniform and thorough grinding. The ground fasteners leave the grinding area via the fastener discharge chute 28 to avoid blockage and are collected in a designated container. The dust collection box 25 effectively collects dust and debris generated during grinding, maintaining a clean working environment and preventing dust and debris from flying around. The position of the processing frame 2 can be adjusted by pushing the handle 27 and sliding rail 26 to accommodate the processing needs of fasteners of different sizes or types. Regular inspection and maintenance of each component ensures the normal operation of the device and the grinding effect. Through the above steps, this novel high-precision fastener processing deburring and grinding device can efficiently and stably complete the deburring and grinding of fasteners, improving processing accuracy and efficiency.
