Description

Technical Field

[0001] This utility model relates to the technical field of bolt rust removal equipment, specifically to a bolt rust removal and polishing equipment. Background Technology

[0002] During maintenance and repair, a large number of bolts of various specifications in the static sealing components of petrochemical plant equipment and pipeline flanges need to be disassembled and reused. Due to the influence of environmental factors during long-term use, the bolts are severely corroded, which can easily lead to poor fit between the bolt and nut, and even affect the stability and reliability of the connection.

[0003] Currently, the traditional method for removing rust from bolts involves soaking them in kerosene and then manually grinding them with a wire brush. This method is labor-intensive, inefficient, and the use of kerosene and other auxiliary materials can easily cause environmental pollution. Utility Model Content

[0004] The purpose of this invention is to design a bolt rust removal and polishing device that can solve the technical problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A bolt rust removal and polishing device includes a worktable. A drive roller and a driven roller are arranged parallel to each other on the top of the worktable. The left ends of the drive roller and the driven roller are horizontally aligned, and the right end of the driven roller is higher than the right end of the drive roller. A polishing machine and a first servo motor are mounted on the top of the worktable. A parallel steel wire wheel is connected to the output end of the polishing machine. The parallel steel wire wheel is located above the drive roller and the driven roller. The first servo motor is connected to the drive roller for transmission.

[0006] Furthermore, both ends of the drive roller are fixed to the top of the worktable via a first bearing seat, and both ends of the driven roller are fixed to the top of the worktable via a second bearing seat.

[0007] Furthermore, the right end of the transmission roller passes through the first bearing seat and is fixedly connected to a first bevel gear, and the output end of the first servo motor is fixedly connected to a second bevel gear that meshes with the first bevel gear.

[0008] Furthermore, a dust suction hood is fixed to the top of the workbench, with the suction port of the dust suction hood aligned with the parallel steel wire wheel. A dust suction pipe communicating with the dust suction hood is provided at the bottom of the workbench, and a vacuum cleaner is connected to the other end of the dust suction pipe.

[0009] Furthermore, a ramp is fixedly connected to the left side of the workbench, and a receiving box is fixedly connected to the lower side of the ramp.

[0010] Furthermore, baffles are provided on both sides of the slope.

[0011] Furthermore, a feeding mechanism is provided on the top of the workbench.

[0012] Furthermore, the feeding mechanism includes a feeding plate fixed to the top of the workbench and inclined, with the lower side of the feeding plate aligned with the side of the drive roller away from the driven roller. The top of the feeding plate is provided with a limiting rod and a knife hole in sequence in the direction away from the driven roller. The bottom of the feeding plate is provided with a rotating shaft, and two oppositely arranged push knives are fixedly connected to the rotating shaft. There are two knife holes, which correspond to the two push knives one by one. The bottom of the feeding plate is fixed with a second servo motor that is drivenly connected to the rotating shaft.

[0013] Furthermore, both ends of the rotating shaft are fixed to the bottom of the feeding plate by a third bearing seat. One end of the rotating shaft passes through the third bearing seat and is fixedly connected to a first pulley. The output end of the second servo motor is fixedly connected to a second pulley. The first pulley and the second pulley are connected by a belt.

[0014] The beneficial effects of this utility model are as follows: By placing the bolt to be derusted between the driven roller and the transmission roller, the first servo motor drives the transmission roller to rotate, the transmission roller drives the bolt to rotate, and the bolt then drives the driven roller to rotate. During the rotation, the driven roller pushes the bolt from the right end of the transmission roller to the left end, so that the bolt passes under the parallel wire wheel, allowing the parallel wire wheel to polish and remove rust from the surface of the bolt. This reduces the labor intensity of workers, improves the efficiency of rust removal, and greatly reduces environmental pollution. Attached Figure Description

Detailed Implementation

[0018] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0019] like Figure 1-3 As shown, a bolt rust removal and polishing device includes a worktable 1. A drive roller 3 and a driven roller 2 are arranged parallel to each other on the top of the worktable 1. Both ends of the driven roller 2 are fixed to the top of the worktable 1 via first bearing seats 7 and second bearing seats 8. The left ends of the drive roller 3 and the driven roller 2 are horizontally aligned, while the right end of the driven roller 2 is higher than the right end of the drive roller 3. The drive roller 3 drives the bolt 25 to rotate, which in turn drives the driven roller 2 to rotate. During rotation, the driven roller 2 pushes the bolt 25 from the right end of the drive roller 3 towards the left end. The workbench 1 is equipped with a polishing machine 4 and a first servo motor 5. The output end of the polishing machine 4 is connected to a parallel steel wire wheel 6, which is located above the drive roller 3 and the driven roller 2. The parallel steel wire wheel 6 is used to remove rust and polish the surface of the bolt 25. The right end of the drive roller 3 passes through the first bearing seat 7 and is fixedly connected to a first bevel gear 9. The output end of the first servo motor 5 is fixedly connected to a second bevel gear 10 that meshes with the first bevel gear 9. The first servo motor 5 drives the second bevel gear 10 to rotate, the second bevel gear 10 drives the first bevel gear 9 to rotate, and the first bevel gear 9 drives the drive roller 3 to rotate.

[0020] A dust hood 11 is fixed to the top of the workbench 1, with the dust suction port of the dust hood 11 aligned with the parallel steel wire wheel 6. A dust suction pipe connected to the dust hood 11 is provided at the bottom of the workbench 1, and the other end of the dust suction pipe is connected to a vacuum cleaner. Under the action of the vacuum cleaner, the dust hood 11 can absorb rust and other debris splashed from the surface of the parallel steel wire wheel 6, reducing environmental pollution. A ramp 12 is fixedly connected to the left side of the workbench 1, and a receiving box 13 is fixedly connected to the lower side of the ramp 12. The polished bolts 25 will fall onto the ramp 12 and then slide into the receiving box 13 for collection. Baffles 14 are provided on both sides of the ramp 12 to prevent the bolts 25 from falling to the ground from both sides of the ramp 12.

[0021] The top of the workbench 1 is equipped with a feeding mechanism, which includes a feeding plate 15 fixed to the top of the workbench 1 and inclined. The lower side of the feeding plate 15 is aligned with the side of the drive roller 3 away from the driven roller 2, so that after the bolt 25 is placed on the top of the feeding plate 15, the bolt 25 rolls from high to low on the top of the feeding plate 15, so that the bolt 25 can fall between the drive roller 3 and the driven roller 2, thereby feeding. The top of the feeding plate 15 is provided with a limiting rod 16 and a knife hole 17 in sequence in the direction away from the driven roller 2. The limiting rod 16 limits the bolt 25 placed on the top of the feeding plate 15. The bottom of the feeding plate 15 is equipped with a rotating shaft 18, and two oppositely arranged push knives 19 are fixedly connected to the rotating shaft 18. There are two knife holes 17, which correspond one-to-one with the two push knives 19. The rotation of the rotating shaft 18 drives the push knives 19 to rotate (e.g., Figure 4 As shown, the pusher 19 rotates counterclockwise, allowing it to push and lift the bolt 25, which is limited by the limiting rod 16, after passing through the cutter hole 17, so that the bolt 25 can roll forward past the limiting rod 16. A second servo motor 20 is fixed to the bottom of the loading plate 15. Both ends of the rotating shaft 18 are fixed to the bottom of the loading plate 15 through the third bearing seat 21. One end of the rotating shaft 18 passes through the third bearing seat 21 and is fixedly connected to the first pulley 22. The output end of the second servo motor 20 is fixedly connected to the second pulley 23. The first pulley 22 and the second pulley 23 are connected by a belt 24. The second servo motor 20 drives the second pulley 23 to rotate, and the second pulley 23 drives the first pulley 22 to rotate through the belt 24. The first pulley 22 drives the rotating shaft 18 to rotate.

[0022] A controller is fixed at the bottom of the workbench 1. The first servo motor 5, the second servo motor 20, the polishing machine 4, and the vacuum cleaner are all electrically connected to the controller. The controller controls the electrical components to start and coordinate their work. This is existing technology, and its principle will not be elaborated here.

[0023] Working principle: like Figure 1-3As shown, when the rust removal and polishing equipment is in use, several bolts 25 to be rusted are arranged in sequence on the top of the loading plate 15. The bolt 25 closest to the transmission roller 3 is limited by the limiting rod 16. Then, the first servo motor 5, the second servo motor 20, the polishing machine 4 and the vacuum cleaner are started, so that the transmission roller 3, the rotating shaft 18 and the parallel steel wire wheel 6 are all rotated, and the dust collection hood 11 performs the adsorption operation. The rotation of the rotating shaft 18 drives the pusher 19 to rotate (e.g., Figure 4 As shown, the pusher 19 rotates counterclockwise, allowing it to push and lift the bolt 25, which is limited by the limiting rod 16, after passing through the cutter hole 17. This allows the bolt 25 to roll from high to low over the limiting rod 16 on the top of the feed plate 15, falling between the drive roller 3 and the driven roller 2. The drive roller 3 drives the bolt 25 to rotate, which in turn drives the driven roller 2 to rotate. During rotation, the driven roller 2 pushes the bolt 25 from the right end to the left end of the drive roller 3, allowing it to pass under the parallel wire wheel 6. This allows the parallel wire wheel 6 to polish and remove rust from the surface of the bolt 25, reducing the labor intensity of workers, improving rust removal efficiency, and greatly reducing environmental pollution. After polishing and rust removal, the bolt 25 finally falls onto the ramp 12 and slides into the receiving box 13 for collection.

[0024] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
