Description

Technical Field

[0001] This invention relates to the field of nut grinding technology, specifically a grinding assembly for processing press-fit nuts. Background Technology

[0002] Currently, most press-fit nuts require external grinding during production. The grinding component of the press-fit nut is used to grind the surface of the press-fit nut. Grinding the surface of the press-fit nut can effectively remove imperfections, improve surface smoothness, ensure a tight fit between the nut and other connecting parts, enhance its corrosion resistance, and extend its service life.

[0003] Existing grinding components for processing press-fit nuts generate a lot of debris during the grinding process. Some of this debris usually splashes during the grinding process. When grinding with a grinding roller, the debris will splash in a fixed direction due to the rotation direction of the grinding roller. The splashed debris undoubtedly increases the difficulty of cleaning and increases manpower consumption. Therefore, we propose a grinding component for processing press-fit nuts.

[0017] To make the objectives, technical solutions, and advantages of the present invention clear and complete, the embodiments of the present invention will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some, not all, embodiments of the present invention, and are merely illustrative of the embodiments of the present invention. They are not intended to limit the embodiments of the present invention. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0018] Example 1, please refer to Figure 1 - Figure 7This invention provides a technical solution: a grinding assembly for processing press-fit nuts, comprising a main mounting plate 1 and a secondary mounting plate 3, both mounted on a machine tool, with a grinding tool 2 disposed between the main mounting plate 1 and the secondary mounting plate 3. The machine tool has a through-type discharge port 15 at its top, with the grinding tool 2 and a collecting frame 12 located above the discharge port 15. A worktable is provided at the top of the machine tool, and press-fit nuts are mounted on the top of the worktable. Guide blocks 17 are fixedly connected to the inner walls of both sides of the discharge port 15, with the two guide blocks 17 positioned opposite each other. The bottom ends of the two guide blocks 17 are fixedly connected to... Triangular blocks 16 are rotatably connected to each other by an inclined plate 21. A compensation groove 25 is provided at the bottom of the machine tool. A column gear 33 is rotatably connected between the inner walls of the two sides of the compensation groove 25. An arc-shaped rack 32 is fixedly connected to the outer walls of both sides of the inclined plate 21. A gear plate 34 meshes with the outer wall of the column gear 33. Multiple sets of equidistant auxiliary devices 36 are arranged inside the compensation groove 25. The auxiliary devices 36 include an air pump fixedly connected inside the compensation groove 25 and an air jet pipe connected to one end of the air pump. Each air jet pipe passes through the inside of the machine tool and is set on the worktable. The adjusting plate of the air pump is fixedly connected to one side of the gear plate 34. During the grinding process, each firing component 20 continuously impacts the inclined plate 21. Through the constraint of the protrusion 22 and the arc groove 23, the inclined plate 21 swings back and forth along its own shaft, shaking off the debris that has accumulated at the inclined end. At the same time, each auxiliary device is continuously activated, and each air pump continuously generates airflow, blowing the debris on the worktable toward the discharge port 15, completing the self-collection of debris and greatly reducing manpower consumption.

[0019] In Example 2, based on Example 1, a mounting groove 4 is provided inside the main mounting plate 1. The rotating shaft of the grinding tool 2 is rotatably connected to the inside of the mounting groove 4. A linkage mechanism is provided inside the mounting groove 4, which includes a connecting belt 5. A horizontal rod 6 is rotatably connected to one inner wall of the mounting groove 4. One end of the horizontal rod 6 passes through the outer wall of the main mounting plate 1 and is rotatably connected to the auxiliary mounting plate 3. An absorption assembly is provided above the horizontal rod 6. The absorption assembly includes a horizontal rod 8 and a suction fan blade 11. The connecting belt 5 is drivenly connected to the horizontal rod. Between the rotating shaft of horizontal rod 16 and grinding tool 2, horizontal rod 28 is rotatably connected between main mounting plate 1 and auxiliary mounting plate 3. A cylindrical gear 7 is fixedly connected to the outer wall of horizontal rod 16, and a cylindrical gear 9, meshing with cylindrical gear 7, is fixedly connected to the outer wall of horizontal rod 28. A meshing assembly 10 is provided on the outer wall of horizontal rod 28, including a helical gear 1 and a helical gear 2. Helical gear 1 is fixedly connected to the outer wall of horizontal rod 28, and helical gear 1 and helical gear 2 mesh with each other. One end of helical gear 2 is fixedly connected to the suction fan blade 11 via a rotating mechanism. A collection frame 12 is fixedly connected between the main mounting plate 1 and the auxiliary mounting plate 3 of the rotating shaft 1. A stabilizing frame is fixedly connected between the outer wall of the rotating shaft 1 and the outer wall of the collection frame 12. The cross-sectional area of ​​the collection frame 12 is larger than that of the grinding tool 2. The collection frame 12 is hollow as a whole and both ends are open. The same partition mesh 14 is fixedly connected between the inner walls of the collection frame 12. A partition mesh 13 is fixedly connected to the end of the collection frame 12 near the suction fan blade 11. The grinding assembly is set on the machine tool, and a through-type drain is opened on the top of the machine tool. The material outlet 15, the grinding tool 2 and the collection frame 12 are all located above the discharge outlet 15. Guide blocks 17 are fixedly connected to the inner walls on both sides of the discharge outlet 15. The positions of the two guide blocks 17 are opposite to each other. Triangular blocks 16 are fixedly connected to the bottom of the two guide blocks 17. An inclined plate 21 is rotatably connected between the two triangular blocks 16. A connecting belt 18 is driven to the outer wall of the horizontal rod 6. One end of the connecting belt 18 is located inside the mounting groove 4. One end of the connecting belt 18 passes through the main mounting plate 1 and the machine tool and is driven to the short shaft 19.

[0020] It should be noted here that: please refer to the attached instruction manual. Figure 3 , 4 5. The cross-section of the collecting frame 12 is much larger than that of the grinding tool 2. The splashing range of metal shavings and other impurities generated during the grinding of the rivet nut by the grinding tool 2 is all within the range of the collecting frame 12. That is, the collecting frame 12 can block the splashing metal shavings and other impurities, avoiding environmental pollution and threats to the safety of operators. The grinding tool 2 is described in the instruction manual. Figure 4When the device rotates clockwise, most of the debris generated by its interaction with the rivet nut will fly between the main mounting plate 1 and the auxiliary mounting plate 3. A small amount of debris will remain on the worktable and machine tool after collision. The partition net 2 14 and partition net 1 13 provide initial blocking of the splashing metal debris and other impurities, while partition net 1 13 provides secondary blocking. More importantly, they protect the suction fan blades 11 and prevent the splashing metal debris and other impurities from affecting the suction effect of the suction fan blades 11. The metal debris blocked by partition net 1 13 or partition net 2 14 will eventually fall into the discharge port 15 below due to its own gravity. It will pass through the discharge port 15 and fall onto the inclined plate 21 or the two guide blocks 17. The two guide blocks 17 have a steeper inclined surface than the inclined plate 21, making it easier for the metal debris and other impurities to fall, which is conducive to the subsequent collection operation.

[0021] In Example 3, based on Example 2, there are two short shafts 19, and a crossbar is fixedly connected between the two short shafts 19. Side plates are rotatably connected to the outer walls of both short shafts 19, and the tops of both side plates are fixedly connected to the bottom of the machine tool. Multiple sets of equidistantly arranged bumping components are fixedly connected to the outer wall of the crossbar. Each set of bumping components includes four firing components 20 that are rotationally symmetrical about the axis of the crossbar and equidistantly arranged. Each firing component 20 includes a rubber rod and a rubber block, and the two are connected... The rubber rod is fixedly connected to the outer wall of the crossbar, and the rubber block is movably connected to the inclined plate 21. A part of the inclined plate 21 is located inside the compensation groove 25, but the two are not in contact. Both sides of the outer wall of the inclined plate 21 are fixedly connected with protrusions 22. The outer wall of the two triangular blocks 16 near the inclined plate 21 is provided with arc-shaped grooves 23. The protrusions 22 are slidably connected inside the arc-shaped grooves 23. An elastic element 24 is fixedly connected between the protrusions 22 and one end of the inner wall of the arc-shaped grooves 23.

[0022] Through the connecting belt 5 and connecting belt 18, the rotation of the grinding tool 2 drives the horizontal bar 6, which in turn drives the short shaft 19. The crossbar between the two short shafts 19 also rotates. Through the meshing helical gears 1 and 2, the suction fan blades 11 rotate simultaneously. The stabilizing frame provides a foundation for the rotation of the suction fan blades 11, ensuring stable rotation and thus ensuring the adsorption effect. The two guide blocks 17 guide and drain the flow, transferring metal debris and other impurities to the inclined plate 21, facilitating the gathering and collection of metal debris and other impurities. In the initial state, before the grinding tool 2 operates, since the two short shafts 19 rotate with the start of the grinding tool 2, the synchronous rotation of the crossbar will drive all the bumping components to operate together. At this time, the rubber blocks will impact the outer wall of the inclined plate 21. Refer to the attached instruction manual. Figure 7By setting the protrusion 22 and the elastic element 24, since the inclined plate 21 is rotatably connected between the two triangular blocks 16 and the rotating shaft is located in the middle of the inclined plate 21, after being impacted by the rubber block, the inclined plate 21 rotates along the shaft, and its lower end will drive the protrusion 22 to compress the elastic element 24. Since the two firing components 20 are separated by a distance, there is also an interval between the impacts of the two adjacent rubber blocks on the inclined plate 21. During this time, the inclined plate 21 loses the external impact force, the force on the elastic element 24 gradually decreases, and its rebound pushes the protrusion 22 back to its original position. When another rubber block impacts the inclined plate 21, the elastic element 24 will be compressed again, and so on. When the grinding tool 2 is started, the inclined plate 21 will be in a state of frequent oscillation around its axis to vibrate the metal chips and other impurities accumulated or retained on the inclined plate 21 into the collection box below, which greatly improves the collection efficiency of metal chips and other impurities generated during the grinding of the rivet nut. Since the protrusion 22 always slides inside the arc groove 23 and is fixedly connected to the inclined plate 21, the swing range of the inclined plate 21 can be limited to keep it within the normal range. When the inclined plate 21 is impacted by the rubber block, the inclined plate 21 deflects inside the compensation groove 25. The opening of the compensation groove 25 provides space for the normal deflection of the inclined plate 21.

[0023] In Example 4, based on Example 3, one end of the short shaft 19 passes through the side plate. Connecting belts 27 are driven to the outer walls of both short shafts 19. One end of the connecting belt 27 passes through the machine tool and is driven to a rotating shaft 28. A stabilizing block is rotatably connected to the outer wall of the rotating shaft 28, which is fixedly connected to the top of the machine tool. A fan blade is fixedly connected to one end of the rotating shaft 28. Two conveying pipes 29 are provided at the top of the machine tool. The components at one end of the two conveying pipes 29 have the same characteristics. The fan blade is located inside the conveying pipe 29. One end of the conveying pipe 29 is fixedly connected to a diversion box 30. One end of the diversion box 30 is fixedly connected to three equally spaced enhanced nozzles 31. The enhanced nozzles 31 are angled downwards. A splash guard 26 is fixedly connected between the two triangular blocks 16.

[0024] The fixed side plate provides a foundation for the stable rotation of the short shaft 19. It is important to note that the flow distribution box 30 has three equally spaced through slots inside. Each through slot connects to the inside of the delivery pipe 29, and each through slot connects to the inside of each enhancement nozzle 31. With the connection of the connecting belt 27, the rotating shaft 28 rotates, thereby driving the fan blades to rotate. The resulting airflow passes through the delivery pipe 29 and the flow distribution box 30, and is finally delivered in equal volumes to the interiors of each enhancement nozzle 31 under the action of the flow distribution box 30. (See the instruction manual attached.) Figure 8As can be seen, the gas flow path here is indicated by the arrow. Because the cross-sectional area of ​​the internal channel of the enhanced nozzle 31 suddenly decreases, according to the principle of fluid mechanics (the increase in flow velocity means the increase in fluid kinetic energy, thereby enhancing the impact force of the fluid), the flow velocity of the airflow will increase, which will blow away the debris stuck on the machine tool. They can only fall through the discharge port 15. The setting of the splash guard 26 greatly reduces the probability of debris splashing to the outside of the collection box, which is conducive to the collection operation.

[0025] Example 5 Based on Embodiment 3, the width of the compensation groove 25 is greater than the width of the inclined plate 21, the arc-shaped rack 32 is located between the inclined plate 21 and the compensation groove 25, the width of the toothed plate 34 is less than the inclined plate 21, the movement trajectories of the arc-shaped rack 32 and the toothed plate 34 do not interfere with each other, the outer walls on both sides of the toothed plate 34 are fixedly connected to the limiting blocks 35, the inner walls on both sides of the compensation groove 25 are provided with limiting grooves, and the limiting blocks 35 are slidably connected inside the limiting grooves.

[0026] It should be noted that the air pump is an existing tool, and its specific working principle will not be explained in detail. When the tilting plate 21 is impacted by the firing component 20, the tilting plate 21 will swing back and forth along its own shaft through the set protrusion 22 and arc groove 23, and simultaneously drive the arc rack 32 to swing back and forth. With the meshing connection of the column gear 33 and the cooperation of the limiting block 35 and the limiting groove, the rack 34 can only move up or down at a fixed tilt angle. This process is fed back to the air pump, so the adjusting end of the air pump sometimes moves away from the inside of the air pump and sometimes moves closer to the inside of the air pump. Then the jet pipe connected to one end will spray gas and act on the work table, blowing the debris on the work table towards the discharge port 15, completing the self-collection of debris and greatly reducing manpower consumption.

[0027] In actual use, through the connection of connecting belt 5 and connecting belt 18, the rotation of the grinding tool 2 drives the horizontal bar 6, which in turn drives the short shaft 19. The crossbar between the two short shafts 19 also rotates. Through the meshing helical gears 1 and 2, the suction fan blades 11 rotate simultaneously. The stabilizing frame provides a foundation for the rotation of the suction fan blades 11, ensuring stable rotation and thus ensuring the adsorption effect. The two guide blocks 17 guide and divert the flow, transferring metal debris and other impurities to the inclined plate 21, facilitating the gathering and collection of metal debris and other impurities. The synchronous rotation of the crossbar drives all the bumping components to operate together. Each rubber block impacts the outer wall of the inclined plate 21. Through the set protrusion 22 and arc groove 23, the inclined plate 21 swings back and forth along its own shaft, and simultaneously drives the arc rack 32 to swing back and forth. With the meshing connection of the column gear 33 and the cooperation of the limiting block 35 and the limiting groove, the toothed plate 34 can only move up or down at the inclined angle. This process is fed back to the air pump, so the adjusting end of the air pump sometimes moves away from the inside of the air pump and sometimes moves closer to the inside of the air pump. Then the jet pipe connected to one end will spray gas and act on the work table, blowing the debris on the work table towards the discharge port 15, completing the self-collection of debris and greatly reducing manpower consumption.
