[0002] If bolts are not stored properly after production, they may rust. Alternatively, bolts may rust after prolonged use in a humid environment. Therefore, bolts need to be derusted and polished to ensure their service life.

[0003] Chinese Patent Publication No. CN213532138U discloses a polishing device for bolt production, comprising a base plate, a cabinet fixedly mounted at the center of the lower surface of the base plate, and a polishing barrel fixedly mounted on the upper surface of the base plate. The polishing barrel is filled with abrasive material, specifically brown corundum. A motor is fixedly mounted at the bottom of the inner wall of the cabinet, and a rotating shaft is vertically and movably connected through the center of the top of the motor. A stainless steel plate is fixedly mounted at the bottom of the polishing barrel, with the lower surface of the stainless steel plate in contact with the upper surface of the base plate. A fixing cavity is formed between the upper and lower surfaces of the base plate and the center of the top of the cabinet.

[0014] Preferably, a connecting plate is provided on the top of the frame, and a cylindrical cover is connected between the connecting plate and the lifting plate. The cylindrical cover has a pleated cylindrical structure, and the lead screw and sliding rod are both located inside the cylindrical cover.

[0015] Preferably, an agitator is installed at the lower part of the lead screw. The agitator includes an integrally connected mounting cylinder and agitator blades.

[0018] On the other hand, the present invention proposes a method for processing the above-mentioned bolt surface rust removal and polishing device, the method comprising the following steps:

[0019] S1. Fix one end of the bolt to be processed to the bottom of the bolt fixing assembly;

[0025] Compared with the prior art, the present invention has the following beneficial technical effects:

[0026] This invention facilitates the placement and removal of bolts, avoids collisions and impacts between bolts, and automatically shakes off any adhering abrasive. During descent, the bolt fixing assembly causes the bolt to rotate and revolve, as well as to wobble. The exposed portion of the bolt fully rubs against the abrasive, achieving rust removal and polishing. Due to the centrifugal force during revolution and the friction with the abrasive, the wobbling assembly causes the bolt to sway within the abrasive, ensuring sufficient friction between the abrasive and the bolt and guaranteeing effective rust removal and polishing. After the bolt moves upward above the abrasive, the wobbling assembly allows the bolt to sway in the air, further helping to shake off any abrasive and rust residue that may be adhering to the bolt.

[0034] Example 1

[0035] like Figures 1-4 As shown in the figure, the bolt surface rust removal and polishing device proposed in this embodiment includes a frame 1, a material box 2, a bolt fixing assembly and a drive mechanism.

[0036] The material box 2 has a cylindrical structure and is filled with abrasive, which can remove rust and polish the bolts when they are rubbed together.

[0037] The bolt fixing assembly is distributed in multiple groups around the central shaft of the material box 2, which can fix multiple bolts at the same time for rust removal and polishing, ensuring processing efficiency.

[0038] The drive mechanism is mounted on the frame 1 and is used to drive multiple sets of bolt fixing components to lift, rotate, and sway. When the height of the bolt fixing components decreases, the bolt fixing components rotate and revolve, accompanied by swaying. The bolt fixing components drive the bolts to move within the abrasive to remove rust and polish the bolts. When the height of the bolt fixing components increases, the bolt fixing components rotate and revolve in the opposite direction, accompanied by swaying. The bolt fixing components drive the bolts to move out of the abrasive to shake off the abrasive on the bolts. Before moving out of the abrasive, the friction between the bolts and the abrasive still has the effect of removing rust and polishing.

[0039] The bolt fixing assembly includes a magnet 3, the bottom surface of which is flat. The bolt to be processed can be attracted by the magnet, thus easily fixing it to the bottom surface of the magnet 3, and easily removing it from the bottom surface of the magnet 3.

[0040] like Figures 1-3 As shown, the drive mechanism includes a rotating shaft 9, a driven gear 10, a driving gear 11, a gear ring 12, a top plate 13, a lifting plate 15, a motor 16, a lead screw 17, a lead screw nut 18, a sliding rod 19, a mounting plate 20, and a wobbling assembly for mounting bolt fixing components. The wobbling assembly is located at the bottom of the rotating shaft 9, which is mounted on the driven gear 10. Multiple driven gears 10 are evenly arranged around the driving gear 11. The driven gear 10 meshes with the driving gear 11 and the gear ring 12 simultaneously. The gear ring 12 is located at the bottom of the lifting plate 15. The driving gear 11 is located at the bottom of the lead screw 17. The top plate 13 is rotatably connected to the rotating shaft 9 and the lead screw 17 simultaneously. The motor 16 is mounted on the mounting plate 20 and is driven by the lead screw 17. The lead screw 17 is vertically arranged and threadedly connected to the lead screw nut 18, which is mounted on the frame 1. The sliding rod 19 is vertically arranged and its two ends are connected to the lifting plate 15 and the mounting plate 20, respectively.

[0041] The output of motor 16 can rotate in both directions. Motor 16 drives lead screw 17 to rotate. Lead screw 17 rotates downward or upward on lead screw nut 18. Lead screw 17 also drives drive gear 11 to rotate. Driven gear 11 drives driven gear 10 to rotate. Driven gear 10 meshes with gear ring 12. Driven gear 10 has both rotation and revolution, so it can drive the wobbling component to rotate and revolve through rotating shaft 9, and then drive the bolt on bolt fixing component to rotate and revolve.

[0042] like Figure 3 As shown, the wobbling assembly includes a mounting post 4, a guide post 5, a baffle 6, a spring 7, and a mounting bracket 8. The mounting post 4 is horizontally slidably mounted on the guide post 5, which is mounted on the mounting bracket 8. Two baffles 6 are slidably mounted on the guide post 5, with the two baffles 6 distributed on both sides of the mounting post 4. The two ends of the spring 7 are connected to the baffles 6 and the mounting bracket 8, respectively. The mounting bracket 8 is located at the bottom of the rotating shaft 9. When the rotating shaft 9 drives the mounting bracket 8 to rotate, the mounting bracket 8 drives the magnet 3 to rotate via the guide post 5 and the mounting post 4, and the bottom of the magnet 3 attracts the bolt. When the bolt rubs against the abrasive in the hopper 2, due to the resistance of the abrasive and the centrifugal force of the bolt's revolution, the mounting post 4 will slide back and forth on the guide post 5, allowing the bolt to wobble while rotating and revolving, thus achieving better friction with the abrasive and better rust removal and polishing. The two baffles 6 can limit the range of motion of the mounting column 4. After the baffle 6 is hit by the mounting column 4, the impact is buffered by the spring 7. When the spring 7 rebounds, it will also use the baffle 6 to push the mounting column 4 away, so that the mounting column 4 can slide back and forth better, that is, better realize the shaking of the bolt, so as to shake off the abrasive and rust that may be attached to the bolt. The buffering of the spring 7 also reduces the noise of the entire device during operation.

[0043] like Figure 1 and Figure 2 As shown, a connecting plate 21 is provided on the top of the frame 1. A cylindrical cover 22 is connected between the connecting plate 21 and the lifting plate 15. The cylindrical cover 22 has a pleated cylindrical structure, and the lead screw 17 and the sliding rod 19 are both located inside the cylindrical cover 22. When the lifting plate 15 is raised or lowered, the cylindrical cover 22 can be folded and stretched, which can always shield and protect the inner structure and ensure the cleanliness of the entire device.

[0044] like Figure 2As shown, an agitator 31 is installed at the lower part of the lead screw 17. The agitator 31 includes an integrally connected mounting cylinder and agitator blades. Multiple agitator blades are evenly distributed around the mounting cylinder, and the agitator blades gradually bend along the circumference of the mounting cylinder from top to bottom. After the bolt comes into contact with the abrasive, it pushes the abrasive away. Although the abrasive will slide down onto the bolt's path due to its own gravity, it cannot completely slide off, and a depression will still appear on the bolt's path. When the lead screw 17 rotates, it drives the agitator 31 to rotate. The agitator 31 agitates the abrasive in the feed box 2 through the agitator blades, thereby making the abrasive evenly distributed and pushing the abrasive to the depression. This allows the bolt to rub against more abrasive when it moves to this point, ensuring the rust removal and polishing effect.

[0045] like Figure 2 and Figure 4 As shown, a base plate 14 is rotatably connected to the rotating shaft 9 and the lead screw 17. An installation rod 23 is provided on the bottom surface of the base plate 14, and a feeding hopper 24 is provided at the bottom end of the installation rod 23. The feeding hopper 24 has a V-shaped feeding groove, which is inclined. The base plate 14 can better fill the groove on the bolt movement path with abrasive through the feeding groove, further ensuring the abrasive's effect on rust removal and polishing of the bolt.

[0046] This embodiment facilitates the placement and removal of bolts, avoids collisions and impacts between bolts, and automatically shakes off any adhering abrasive, preventing collisions and wear between bolts. In use, the bolt is fixed to the bolt fixing assembly, which is then driven to descend via a drive mechanism. During descent, the bolt fixing assembly causes the bolt to rotate and revolve, and also to wobble. The exposed portion of the bolt can fully rub against the abrasive, achieving rust removal and polishing. The driven gear 10 revolves around the driving gear 11 and also rotates. The driven gear 10, through the rotating shaft 9 and the wobbling assembly, drives the bolt to rotate and revolve. Simultaneously, due to the centrifugal force during revolution and the friction with the abrasive, the wobbling assembly causes the bolt to wobble within the abrasive, ensuring sufficient friction between the abrasive and the bolt, guaranteeing effective rust removal and polishing. After the bolt moves upward above the abrasive, the wobbling assembly allows the bolt to wobble in the air, further helping to shake off any adhering abrasive and rust.

[0047] Example 2

[0048] This embodiment presents a bolt surface rust removal and polishing device. Compared to Embodiment 1, this embodiment, as follows: Figure 5As shown, the bolt fixing assembly includes a mounting sleeve 25 with a mounting groove at the bottom, a plurality of clamping plates 26 rotatably connected to the top surface of the mounting groove and evenly distributed around the mounting groove, a connecting frame 27 rotatably connected to one end of the clamping plate 26, a movable ring 28 rotatably connected to the other end of the connecting frame 27, a slide rod 30 vertically disposed on the movable ring 28 and slidably connected to the mounting sleeve 25, and a threaded knob 29 vertically rotatably disposed on the movable ring 28 and threadedly connected to the mounting sleeve 25.

[0049] In this embodiment, when fixing the bolt, one end of the bolt is inserted into the mounting groove, and the threaded knob 29 is rotated. The threaded knob 29 drives the moving ring 28 to descend, the moving ring 28 drives the connecting frame 27 to rotate, and the connecting frame 27 drives the clamping plate 26 to rotate inward. Thus, multiple clamping plates 26 are used to clamp one end of the bolt to fix the bolt. The operation is very convenient.

[0050] Example 3

[0051] The processing method of the bolt surface rust removal and polishing device in Embodiments 1 and 2 above includes the following steps:

[0052] S1. Fix one end of the bolt to be processed to the bottom of the bolt fixing assembly;

[0053] S2. Start motor 16. Motor 16 drives lead screw 17 to rotate clockwise. Lead screw 17 screws downward on lead screw nut 18. Lead screw 17 drives drive gear 11 to rotate. Drive gear 11 drives driven gear 10 to rotate. Driven gear 10 rotates on its own axis and revolves around drive gear 11. Finally, the bolt's rotation and revolution are realized. The shaking component is used to realize the shaking. The bolt gradually extends into the abrasive in the material box 2 and rubs against the abrasive to achieve rust removal and polishing of the bolt.

[0054] S3. When the bolt moves to the lowest position, the motor 16 drives the lead screw 17 to rotate counterclockwise. The lead screw 17 rotates upward, and the bolt gradually moves out of the abrasive. During the bolt's removal process, it will still rub against the abrasive and continue to perform rust removal and polishing. After the bolt is completely removed from the abrasive, due to the rotation and revolution of the driven gear 10 and the action of the shaking component, the bolt can be shaken under the action of centrifugal force, thereby automatically shaking off the abrasive on the bolt.

[0055] S4. Repeat steps S2 and S3 until the exposed part of the bolt is rust-removed and polished to the required standard. Since one end of the bolt is fixed first, that end is not exposed. When the bolt rubs against the abrasive, that end cannot be rust-removed and polished, so the subsequent step S5 is required.

[0056] S5. Secure the other end of the bolt using the bolt fixing assembly, and repeat steps S2-S4 to remove rust and polish the unexposed end of the bolt, thereby ensuring the comprehensiveness of the bolt rust removal and polishing.

[0057] S6. Remove the bolts from the bolt fixing assembly after they have been completely derusted and polished. The bolts have undergone thorough rust removal and polishing, which extends their service life.

[0058] When using the magnet 3 from Embodiment 1 to secure the bolt, the magnet 3 is maintained at a height that will not attract rust that has been worn away from the bolt. Even if rust is attracted to the magnet 3, it can be cleaned off later. The rust on the bolt has been removed by the abrasive, and the bolt has been polished, making it difficult for rust to re-adhere to the smooth, finished bolt.

[0059] When the clamp 26 in Embodiment 2 is used to fix the bolt, the abrasive can effectively grind away the rust on the bolt, and the rust will not re-adhere to the bolt.

[0060] Example 4

[0061] This embodiment presents a bolt surface rust removal and polishing device. The differences between this embodiment and Embodiments 1 and 2 are as follows: Figure 6 As shown, the material box 2 is rotatably mounted on the frame 1 via its bottom. The lifting plate 15 is equipped with a transmission assembly for driving the material box 2 to reciprocate and swing. The transmission assembly includes a lifting column 36 mounted on the lifting plate 15, a rack 37 vertically mounted at the bottom of the lifting column 36, a gear 38 meshing with the rack 37, a support frame 41 mounted on the frame 1, a mounting shaft 39 rotatably mounted on the support frame 41, a turntable 40 coaxially mounted with the gear 38 via the mounting shaft 39, a swing rod a35 rotatably connected to the turntable 40 at one end, a swing rod b33 rotatably connected to the other end of the swing rod a35, and a connecting rod 32 rotatably connected to the swing rod b33 and the material box 2 at both ends respectively. The support frame 41 is equipped with a fixed shaft 34 for rotatably mounting the swing rod b33. The distance from the fixed shaft 34 to the rotatable connection point of the swing rod b33 and the material box 2 is less than the distance from the fixed shaft 34 to the rotatable connection point of the swing rod b33 and the swing rod a35, thus forming a force-saving lever, which drives the material box 2 to vibrate with less force.

[0062] In this embodiment, the material box 2 itself also vibrates. The lifting plate 15 drives the lifting column 36 to rise and fall, and the lifting rack 37 drives the gear 38 to rotate. The gear 38 drives the turntable 40 to rotate through the mounting shaft 39. The turntable 40 drives the swing rod b33 to swing back and forth through the swing rod a35. The swing rod b33 drives the material box 2 to swing back and forth through the connecting rod 32, thereby causing the abrasive in the material box 2 to vibrate and improve the rust removal and polishing effect of the abrasive on the bolts.

[0063] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.

8. A method for treating bolt surfaces with rust removal and polishing according to claim 1, characterized in that, Includes the following steps: S1. Fix one end of the bolt to be processed to the bottom of the bolt fixing assembly; S2. Start the motor (16). The motor (16) drives the lead screw (17) to rotate clockwise. The lead screw (17) is screwed downward on the lead screw nut (18). The lead screw (17) drives the drive gear (11) to rotate. The drive gear (11) drives the driven gear (10) to rotate. The driven gear (10) rotates on its own axis and revolves around the drive gear (11). Finally, the bolt rotates on its own axis and revolves around the drive gear (11). The bolt is also shaken by the shaking component. The bolt gradually extends into the abrasive in the material box (2) and rubs against the abrasive to remove rust and polish the bolt. S3. When the bolt is moved to the lowest position, the motor (16) drives the lead screw (17) to rotate counterclockwise. The lead screw (17) rotates upward and the bolt gradually moves out of the abrasive. After the bolt is completely removed from the abrasive, due to the rotation and revolution of the driven gear (10) and the action of the shaking component, the abrasive on the bolt can be shaken off under the action of centrifugal force. S4. Repeat steps S2 and S3 until the exposed bolt parts are rust-removed and polished to the required standard. S5. Secure the other end of the bolt using the bolt fixing assembly, and repeat steps S2-S4; S6. Remove the bolts from the bolt fixing assembly after they have been completely derusted and polished.
