Description

Technical Field

[0001] This utility model relates to the field of nut processing technology, and in particular to a burr removal device for nut processing. Background Technology

[0002] In the field of mechanical manufacturing, nuts are basic fasteners, and their processing quality directly affects assembly accuracy and connection reliability. During the processing of nuts such as cold heading, tapping, and stamping, burrs are easily generated at the end face edges, hexagonal edges, etc. due to the plastic deformation of the material or the cutting residue of the tool. If these burrs are not removed in time, they will not only cause thread fit jamming and abnormal torque during assembly, but may also fall off due to vibration and friction during use, causing hidden dangers such as equipment wear and oil circuit blockage. Especially in high-precision fields such as automobiles and aerospace, burr residue can even cause safety risks.

[0003] Currently, deburring of nuts mainly involves operators using hand files, sandpaper, or specialized deburring tools to grind and clean the burrs on individual nuts. While this method can target specific burrs, it has significant limitations. On one hand, manual operation is extremely inefficient, and processing a single nut takes a long time, making it difficult to meet the needs of large-scale production. On the other hand, the quality of manual grinding is affected by factors such as experience and physical strength, easily leading to problems such as missed areas, over-grinding, or uneven processing, resulting in poor product consistency. Therefore, a deburring device for nut processing is proposed to solve the above problems. Utility Model Content

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A burr removal device for nut processing includes a base plate with multiple circular holes. Each circular hole contains a cylinder, and gears are fixedly connected to the top sides of each cylinder. Threaded posts are fixedly connected to the top sides of each gear, and fixed discs are fixedly sleeved on the outer sides of each threaded post.

[0015] 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.

[0016] Example: Refer to Figure 1-4A burr removal device for nut processing includes a base plate 1 with multiple circular holes. Each circular hole contains a cylinder 2, and gears 3 are fixedly connected to the top of each cylinder 2. Threaded posts 4 are fixedly connected to the top of each gear 3, and fixed discs 5 are fixedly sleeved on the outer sides of each threaded post 4. Two fixed plates 6 are fixedly mounted on the top of the base plate 1, and a reciprocating moving assembly is provided between the two fixed plates 6. A toothed plate 11 is provided between the two fixed plates 6 via the reciprocating moving assembly, and the toothed plate 11 meshes with the multiple gears 3. Two mounting plates 13 are fixedly mounted on the top of the base plate 1, and a... A transmission assembly is provided, and a grinding assembly is installed between the two mounting plates 13 via the transmission assembly. The transmission assembly includes a rotating rod 14 positioned between the two mounting plates 13. Both ends of the rotating rod 14 are rotatably connected to the opposite surfaces of the two mounting plates 13. A second synchronous pulley 15 and a first synchronous pulley 12 are respectively fixedly sleeved onto the other ends of the rotating rod 14 and the lead screw 8. The second synchronous pulley 15 and the first synchronous pulley 12 share the same synchronous belt 16. The grinding assembly includes a connecting plate 21 fixedly connected between the two mounting plates 13. The connecting plate 21 has multiple circular holes, each containing a rotating column 18. Each of the rotating rods 18 has a grinding brush 20 fixedly connected to its bottom end. Multiple grinding brushes 20 are located on one side of multiple threaded columns 4. Second bevel gears 19 are fixedly connected to the top of each rotating column 18. Multiple first bevel gears 17 are fixedly sleeved on the outside of the rotating rod 14, and these first bevel gears 17 mesh with the multiple second bevel gears 19. A first synchronous pulley 12 is fixedly sleeved on the other end of the lead screw 8. The first synchronous pulley 12 and the second synchronous pulley 15 share the same synchronous belt 16. Therefore, under the meshing transmission of the synchronous belt 16, the second synchronous pulley 15 synchronously drives the rotating rod 14 connected to it to rotate. Multiple first bevel gears 17 are fixedly sleeved on the outer side. The multiple first bevel gears 17 mesh with multiple second bevel gears 19 respectively. Therefore, under the meshing transmission of the multiple first bevel gears 17, the multiple second bevel gears 19 will synchronously drive the rotating column 18 connected to them to rotate. This causes the grinding brushes 20, which are fixedly connected to the bottom of the multiple rotating columns 18, to begin to deburr the nuts outside the threaded column 4. During the grinding process, the nuts are always rotating, so the grinding brushes 20 can avoid the situation of only grinding one place, and can achieve all-round grinding and can grind multiple nuts at the same time.

[0017] Specifically, the reciprocating motion assembly includes a motor 7 fixedly installed on one side of the right fixed plate 6. The output end of the motor 7 rotates through the two fixed plates 6 and is fixedly connected to the lead screw 8. A guide rod 9 is fixedly installed on the opposite side of the two fixed plates 6. A slider 10 is threadedly sleeved on the lead screw 8 and the guide rod 9. By setting the motor 7, when it is necessary to grind the burrs on the surface of the nut, the motor 7 is started to drive the lead screw 8 to rotate, thereby causing the slider 10, which is threaded on the lead screw 8, to drive the toothed plate 11 fixedly connected on one side to reciprocate along the guide rod 9. Since the toothed plate 11 meshes with multiple gears 3, under the meshing transmission of the toothed plate 11, the multiple gears 3 will synchronously drive the threaded post 4 fixedly connected on the top side to rotate, thereby causing the nut threaded on the threaded post 4 to rotate synchronously. As the toothed plate 11 reciprocates, the nut outside the threaded post 4 will also reciprocate synchronously, so that the multiple grinding wheels 20 can grind the nut in all directions when rotating.

[0018] Specifically, two limiting rings are fixedly sleeved on the outer side of each of the multiple rotating columns 18. The sides of the two limiting rings that are close to each other are respectively attached to the top and bottom sides of the connecting plate 21. The bottom side of the base plate 1 is fixedly installed with four support legs. By setting multiple sets of limiting rings, the multiple sets of limiting rings can play a limiting role when the multiple rotating columns 18 rotate, so that they can only rotate and will not shift up or down, ensuring that the bevel gears always maintain a meshing state.

[0019] All electrical components mentioned in this article are connected to an external main controller and 220V AC mains power. The main controller can be any conventional known device, such as a computer, that can control the operation of the electrical components mentioned in the article.

[0020] In use: Multiple nuts to be deburred are sequentially threaded onto their corresponding threaded posts 4. After all nuts are installed, the motor 7 is started. The motor 7 drives the lead screw 8 to rotate synchronously. Since the lead screw 8 and the slider 10 are connected by external threads, and the slider 10 is limited by the guide rod 9, the slider 10 will reciprocate linearly along the guide rod 9. The toothed plate 11, fixedly connected to one side of the slider 10, moves synchronously with the slider 10. The toothed plate 11 meshes with multiple gears 3. Under the meshing transmission of the toothed plate 11, the multiple gears 3 will rotate synchronously, thereby driving the threaded posts 4 fixedly connected to their respective top sides to rotate together. This causes the nuts on the threaded posts 4, connected by external threads, to rotate synchronously. Simultaneously, the other end of the lead screw 8 is fixedly fitted with a first synchronous pulley 12. The first synchronous pulley 12 and the second synchronous pulley 15 are meshed and transmitted through the same synchronous belt 16. Therefore, the second synchronous pulley... The step wheel 15 rotates synchronously with the first synchronous wheel 12, driving the connected rotating rod 14 to rotate as well. Multiple first bevel gears 17, which are fixedly sleeved on the outside of the rotating rod 14, also rotate synchronously. Since these first bevel gears 17 mesh with their corresponding second bevel gears 19, under the action of meshing transmission, the multiple second bevel gears 19 will synchronously drive their respective connected rotating columns 18 to rotate. Finally, the grinding brush 20, which is fixedly connected to the bottom of the rotating column 18, starts to rotate, and performs burr grinding on the nut on the threaded column 4. During the grinding process, the nut is always in a state of rotation, and the grinding brush 20 also keeps rotating. The relative movement of the two allows the grinding brush to evenly contact the surface of the nut, completely avoiding the problem of local missed grinding caused by grinding in one direction. This achieves all-round, dead-angle-free burr cleaning of the nut, allowing multiple nuts to complete burr processing in the same cycle, greatly improving the overall processing efficiency.
