Description

Technical Field

[0001] This invention relates to the field of polishing technology, specifically to a polishing equipment and method for steel structure materials based on automatic application of polishing agent. Background Technology

[0002] Steel structures are structures made of steel materials and are one of the main types of building structures. In steel structure production, polishing of raw materials is an essential process to ensure the smoothness and shine of the steel structure and improve product quality.

[0003] Polishing liquid has good degreasing, rust prevention, cleaning and brightening properties, and can make products show a true metallic texture. Therefore, some manufacturers choose to use polishing liquid as an aid in polishing. Specifically, the polishing liquid should first be applied to the polishing surface of the material, then the material should be polished, and finally the residue and polishing liquid on the surface of the material should be wiped off.

[0004] Nowadays, the above operations are usually carried out separately. The application of polishing liquid, polishing and wiping cleaning of materials are generally carried out using different equipment. In specific operations, workers need to disassemble and assemble materials on different equipment, which leads to a significant increase in workload, reduced work efficiency and affects the production progress of steel structures.

[0044] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on 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.

[0045] Furthermore, elements in this invention are referred to as being "fixed to" or "set on" another element, which may be directly on the other element or may also include an intervening element. When an element is considered to be "connected" to another element, it may be directly connected to the other element or may also include an intervening element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only possible implementations.

[0046] Please see Figures 1-11 In this embodiment of the invention, the steel structure material polishing equipment based on automatic polishing agent application includes a first vertical plate 1 and a second vertical plate 2 arranged opposite to each other, and further includes:

[0047] A placement platform 40 is movably disposed between the first vertical plate 1 and the second vertical plate 2 for placing materials to be processed. The placement platform 40 is connected to a lifting mechanism installed between the first vertical plate 1 and the second vertical plate 2.

[0048] A horizontal plate 3 is movably disposed between the first vertical plate 1 and the second vertical plate 2, and is connected to a threaded drive mechanism installed between the first vertical plate 1 and the second vertical plate 2. The threaded drive mechanism can drive the mounting frame 4 to move between the first vertical plate 1 and the second vertical plate 2. The mounting frame 4 is also rotatably mounted on the horizontal plate 3. Rotary wheels 11, polishing wheels 12 and wiping discs 13 are rotatably mounted on the mounting frame 4 and are equidistantly distributed along the circumference.

[0049] Three points require further explanation;

[0050] Firstly, the bottom of the rotary wheel 11 is equipped with a polishing cloth, and the rotating shaft of the rotary wheel 11 is a conduit. The conduit is rotatably connected to the outlet of the external pump body, and the inlet of the pump body is connected to the polishing liquid storage container. The pump body is used to pump polishing liquid into the rotary wheel 11 through the conduit. Then, the polishing liquid is applied to the surface of the steel structure material through the polishing cloth at the bottom of the rotary wheel 11. Since the mounting frame 4 needs to rotate during the polishing process to switch between different work positions, the pump body and the polishing liquid storage container are mounted on the mounting frame 4.

[0051] Secondly, this application does not impose specific limitations on the specific specifications of the polishing wheel 12, which can be selected according to actual needs;

[0052] Third, the bottom of the wiping disc 13 is equipped with a cleaning cloth. When the wiping disc 13 corresponds to the steel structure material on the placement platform 40, the power mechanism drives the wiping disc 13 to rotate, thereby wiping and cleaning the polished material surface to remove residues and polishing liquid from the material surface.

[0053] An elastic transmission mechanism is installed on the horizontal plate 3 and connected to the rotation shaft of the mounting frame 4. The elastic transmission mechanism is triggered at the end of the stroke when the horizontal plate 3 moves toward the first vertical plate 1 or the second vertical plate 2, and can drive the mounting frame 4 to rotate so that the positions of the rotating wheel 11, the polishing wheel 12 and the wiping disc 13 change. The rotating wheel 11, the polishing wheel 12 and the wiping disc 13 sequentially apply polishing liquid, polish and wipe clean the material surface on the placement table 40.

[0054] The power mechanism is located on the mounting frame 4 and can be connected to the rotating wheel 11, the polishing wheel 12 or the wiping disc 13.

[0055] Taking the attached diagram as an example, during use, the worker fixes the material to be processed onto the placement table 40. The entire polishing process is divided into three stages:

[0056] In the first stage, the rotating wheel 11 corresponds to the placement table 40 (i.e., the central axis of the rotating wheel 11 is perpendicular to the center line of the placement table 40), and the power mechanism is connected to the rotating shaft of the rotating wheel 11. Thus, the power mechanism drives the rotating wheel 11 to rotate, and the threaded drive mechanism works in the forward direction, driving the horizontal plate 3 to move toward the first vertical plate 1. During the first part of this movement, the lifting mechanism is triggered, causing the placement table 40 to lift the material until the surface of the material contacts the bottom of the rotating wheel 11. After the horizontal plate 3 moves to the end of its stroke, the elastic transmission mechanism is triggered, driving the mounting frame 4 to deflect 120°. At the same time, the placement table 40 moves the material down, the polishing wheel 12 corresponds to the material, and the power mechanism is connected to the rotating shaft of the polishing wheel 12. In this stage, the rotating wheel 11 completes the application of polishing liquid to the surface of the material.

[0057] In stage two, the power mechanism drives the polishing wheel 12 to rotate, the threaded drive mechanism works in reverse, driving the horizontal plate 3 to move toward the second vertical plate 2, the lifting mechanism is triggered, causing the placement table 40 to lift the material, so that the surface of the material contacts the bottom of the polishing wheel 12. After the horizontal plate 3 moves to the end of its stroke, the elastic transmission mechanism is triggered, driving the mounting frame 4 to deflect 120° again, the placement table 40 moves the material down, the wiping disc 13 corresponds to the material, and the power mechanism is connected to the rotating shaft of the wiping disc 13. In this stage, the polishing wheel 12 completes the polishing treatment on the surface of the material.

[0058] In stage three, the power mechanism drives the wiping disc 13 to rotate, the threaded drive mechanism works in the forward direction, driving the horizontal plate 3 to move toward the first vertical plate 1, the lifting mechanism is triggered, causing the placement table 40 to lift the material, so that the surface of the material contacts the bottom of the wiping disc 13. In this stage, the wiping disc 13 completes the wiping treatment on the surface of the material, removing the residue and polishing liquid from the surface of the material.

[0059] In summary, through the cooperation between various mechanisms and components, the threaded drive mechanism drives the horizontal plate 3 to reciprocate between the first vertical plate 1 and the second vertical plate 2. At the end of each stroke, the elastic transmission mechanism is triggered, causing the mounting frame 4 to rotate, thereby switching the positions of the rotating wheel 11, polishing wheel 12, and wiping disc 13. Finally, the rotating wheel 11, polishing wheel 12, and wiping disc 13 can sequentially apply polishing liquid, polish, and wipe clean the material surface on the placement table 40. This equipment integrates the functions of polishing liquid application, polishing, and wiping cleaning, which can effectively reduce the workload of workers and has a high degree of automation, effectively improving work efficiency and providing an effective guarantee for the production progress of steel structures.

[0060] Please refer to it again. Figure 4 , Figure 5 , Figures 7-10The elastic transmission mechanism includes a bidirectional moving component mounted on the horizontal plate 3 and a bidirectional ejector component connected to the bidirectional moving component. The bidirectional ejector component is triggered at the end of the stroke of the horizontal plate 3 and can cause the bidirectional moving component to drive the mounting frame 4 to rotate. The bidirectional moving component includes a first movable seat 23 slidably disposed on the horizontal plate 3 and a ratchet 22 rotatably mounted on the horizontal plate 3. The rotation shaft of the ratchet 22 is connected to the rotation shaft of the mounting frame 4 through a transmission belt 21.

[0061] The first movable seat 23 has multiple mounting slots equidistantly arranged on both sides, and each mounting slot has a pawl that engages with the ratchet 22 hinged in it. The pawls on both sides face opposite directions, and the pawls are also connected to a torsion spring located in the mounting slot.

[0062] A second movable seat 24 is slidably mounted on the horizontal plate 3. The bidirectional ejection assembly includes two cylinders 26 fixedly mounted on the second movable seat 24 and crossbars 27 slidably mounted in the two cylinders 26 respectively. One end of each crossbar 27 is fixed to the first movable seat 23, and the other end is fixedly connected to a first column 31. A second column 32 is fixed on the second movable seat 24. The first column 31 and the second column 32 cooperate with a limiting plate 25 fixedly mounted between the first vertical plate 1 and the second vertical plate 2. A frustum 28 fixed to the crossbar 27 is slidably mounted in the cylinder 26. A first columnar spring 29 and a second columnar spring 30 are respectively connected to the two sides of the frustum 28 and sleeved on the outer periphery of the crossbar 27. The ends of the first columnar spring 29 and the second columnar spring 30 away from the frustum 28 abut against the inner wall of the cylinder 26.

[0063] Please refer to it again. Figure 11 The bottom of the limiting plate 25 is provided with a rectangular groove and an inclined groove 2505. The second column 32 extends into the inclined groove 2505 and is slidably connected to the limiting plate 25. The first column 31 extends into the rectangular groove and is slidably connected to the limiting plate 25. The rectangular groove includes a first straight section 2501, a first vertical section 2502, a second straight section 2503, and a second vertical section 2504 connected together.

[0064] Taking the attached diagram as an example, the first column 31 is located at the connection between the first straight section 2501 and the second vertical section 2504, and the second column 32 is located at one end of the inclined groove 2505 near the second vertical plate 2.

[0065] When the horizontal plate 3 moves toward the first vertical plate 1, the first column 31 slides in the first straight section 2501, and the second column 32 slides in the inclined groove 2505. Thus, the second column 32 slides with the limiting plate 25, causing the second movable seat 24 to slide close to the ratchet 22 on the horizontal plate 3. Since the first column 31 is located in the first straight section 2501 at this time, the second movable seat 24 drives the cylinder 26 to slide together on the horizontal bar 27, causing the first columnar spring 29 to be compressed.

[0066] When the horizontal plate 3 moves to the end of its stroke, the first column 31 reaches the connection between the first straight section 2501 and the first vertical section 2502, and the second column 32 reaches the end of the inclined groove 2505 near the first vertical plate 1. At this time, the first column spring 29 rebounds, causing the horizontal bar 27 to push the first movable seat 23 to slide on the horizontal plate 3 away from the center of the horizontal plate 3. The first column 31 moves to the connection between the first vertical section 2502 and the second straight section 2503. During this process, the pawl on one side of the first movable seat 23 flips when it passes the ratchet 22, while the pawl on the other side does not flip when it passes the ratchet 22, thus causing the ratchet 22 to rotate. Then, the rotating shaft of the ratchet 22 drives the mounting bracket 4 to rotate 120° through the transmission belt 21 to change the position of the rotating wheel 11, the polishing wheel 12, and the wiping disc 13.

[0067] Subsequently, when the horizontal plate 3 moves toward the second vertical plate 2, the first column 31 moves toward the second vertical plate 2 within the second straight section 2503, and the second column 32 slides with the limiting plate 25 again through the inclined groove 2505, so that the second movable seat 24 slides away from the ratchet 22. Correspondingly, the cylinder 26 moves together with the second movable seat 24, and the second columnar spring 30 is compressed.

[0068] When the first column 31 moves to the connection between the second straight section 2503 and the second vertical section 2504, the second columnar spring 30 will rebound. Then, the first column 31 moves to the connection between the second vertical section 2504 and the first straight section 2501. The crossbar 27 then drives the first movable seat 23 to slide towards the center of the horizontal plate 3. At this time, the pawl on one side of the first movable seat 23 does not flip when it passes the ratchet 22, and drives the ratchet 22 to rotate. The pawl on the other side flips when it passes the ratchet 22. The ratchet 22 rotates in the same direction each time, so as to ensure that the mounting bracket 4 rotates in the same direction each time, and ensure that the rotating wheel 11, polishing wheel 12 and wiping disc 13 change positions in the normal order.

[0069] It should be further explained that, since the first movable seat 23 and the second movable seat 24 are slidably connected to the horizontal plate 3, a guide rail (not labeled in the figure) is provided on the horizontal plate 3 for slidingly guiding the first movable seat 23 and the second movable seat 24.

[0070] Please refer to it again. Figure 4 , Figure 5 . Figure 7 as well as Figure 8 The power mechanism includes a second drive motor 8 installed at the bottom of the mounting frame 4 and a first bevel gear 9 fixedly installed on the output shaft of the second drive motor 8. The mounting frame 4 is provided with three sets of telescopic components. One end of the telescopic component is connected to the first bevel gear 9. A fourth bevel gear 17 is fixed on the rotation shaft of the rotating wheel 11, the polishing wheel 12 and the wiping disc 13 respectively. The other end of the telescopic component can be connected to the fourth bevel gear 17.

[0071] The telescopic assembly includes a rotating shaft 14 rotatably mounted on the mounting frame 4, a slider 18 slidably mounted on the mounting frame 4, and a sleeve 15 rotatably mounted on the slider 18 and slidably fitted with the rotating shaft 14 through a concave-convex structure. A second bevel gear 10, meshing with the first bevel gear 9, is fixed to one end of the rotating shaft 14 facing the first bevel gear 9. A third bevel gear 16, engaging with the fourth bevel gear 17, is fixed to one end of the sleeve 15 away from the first bevel gear 9. A protruding post 1801 is also fixed to the slider 18. A first ring body 19 and a second ring body 20 are fixedly connected to the horizontal plate 3. The inner wall of the first ring body 19 has a recess 1901, and the outer wall of the second ring body 20 has a protrusion 2001 adapted to the recess 1901. A gap is reserved between the inner walls of the first ring body 19 and the second ring body 20. The protruding post 1801 extends into the gap and is slidably connected to the first ring body 19 and the second ring body 20.

[0072] Furthermore, the concave-convex structure includes two strip-shaped protrusions on the outer wall of the rotating shaft 14 and two strip-shaped grooves on the inner wall of the sleeve 15, and the strip-shaped grooves are adapted to the strip-shaped protrusions, and both are parallel to the central axis of the rotating shaft 14 and the sleeve 15.

[0073] Secondly, it should be added that the gap between the first ring body 19 and the second ring body 20 is constant and equal to the diameter of the protrusion 1801.

[0074] During the processing, the second drive motor 8 works, and its output shaft drives the rotating shaft 14 to rotate through the first bevel gear 9 and the second bevel gear 10. Then, the rotating shaft 14 drives the sleeve 15 and the third bevel gear 16 to rotate through the strip protrusion and the strip groove.

[0075] Each time the mounting bracket 4 rotates, the slider 18 makes a circular motion, and the protrusion 1801 moves within the gap between the first ring body 19 and the second ring body 20. When the protrusion 1801 moves to the space between the recess 1901 and the protrusion 2001, the slider 18 makes room, and thus the slider 18 drives the sleeve 15 to slide on the mounting bracket 4 until the third bevel gear 16 and the fourth bevel gear 17 mesh. Then, the rotating shafts of the processing tools (rotary wheel 11, polishing wheel 12 and wiping disc 13) corresponding to the placement table 40 can rotate, while the other two processing tools do not rotate. On the one hand, this can effectively reduce the load on the second drive motor 8, and on the other hand, it can prevent the polishing liquid on the rotary wheel 11 from being splashed onto the material surface during processing, resulting in poor cleaning effect of the wiping disc 13.

[0076] Please refer to it again. Figure 2 , Figure 3 , Figure 5 as well as Figure 8 The threaded drive mechanism includes a lead screw 6 rotatably mounted between the first vertical plate 1 and the second vertical plate 2, a guide rod 7 fixed between the first vertical plate 1 and the second vertical plate 2, and a threaded sleeve 601 and a guide sleeve 701 respectively sleeved on the lead screw 6 and the guide rod 7. A first drive motor 5 is also mounted on the side of the first vertical plate 1, and the output end of the first drive motor 5 is connected to the lead screw 6. The horizontal plate 3 is fixedly mounted between the threaded sleeve 601 and the guide sleeve 701. The threaded sleeve 601 is threadedly connected to the lead screw 6, and the guide sleeve 701 is slidably connected to the guide rod 7.

[0077] The first drive motor 5 is a servo motor with bidirectional drive at the output end, so as to drive the lead screw 6 to rotate in the forward or reverse direction, thereby making the horizontal plate 3 slide back and forth between the first vertical plate 1 and the second vertical plate 2. The lead screw 6 has high driving accuracy and is more suitable for use in processing.

[0078] Secondly, it should be emphasized that during processing, because the polishing wheel 12 needs to operate at a high speed, the mounting bracket 4 may shift due to poor stability. This could lead to shifts in the positions of the rotating wheel 11, the polishing wheel 12, and the wiping disc 13. For this, please refer to... Figure 4 Since the rectangular groove can limit the crossbar 27 through the first column 31, the ratchet 22 cannot rotate clockwise. However, the ratchet 22 can rotate counterclockwise. Therefore, the rotation direction of the output shaft of the second drive motor 8 needs to be specified to ensure that during the processing, the force between the rotating wheel 11, polishing wheel 12 and wiping disc 13 and the material causes the force on the mounting frame 4 to be clockwise, so as to avoid the mounting frame 4 from rotating counterclockwise due to instability.

[0079] Please refer to it again. Figure 2, Figure 3 as well as Figure 6 The lifting mechanism includes a lifting plate 39 with its two ends slidably connected to the first vertical plate 1 and the second vertical plate 2 respectively. The placement platform 40 is connected to multiple sets of elastic support structures installed on the lifting plate 39. The lifting plate 39 is fixedly connected to a connecting plate 35. The connecting plate 35 is provided with a sliding groove. A third column 33 is slidably disposed in the sliding groove and fixedly connected to the threaded sleeve 601 by a connecting arm 34. The sliding groove includes a first inclined section 3501, a horizontal section 3502 and a second inclined section 3503 connected in sequence.

[0080] In detail, the elastic support structure includes a guide cylinder 36 fixedly installed on the lifting plate 39, a vertical rod 37 slidably disposed in the guide cylinder 36, and a third columnar spring 38 disposed in the guide cylinder 36. One end of the third columnar spring 38 is connected to the inner wall of the guide cylinder 36, and the other end is connected to the vertical rod 37. The end of the vertical rod 37 away from the lifting plate 39 is fixed to the placement platform 40.

[0081] Whenever the horizontal plate 3 moves, the threaded sleeve 601 drives the third column 33 to move together through the connecting arm 34. During the first and second strokes of the third column 33, it will slide with the connecting plate 35 through the first inclined section 3501 and the second inclined section 3503, causing the connecting plate 35 to drive the lifting plate 39 to rise or fall. When the lifting plate 39 rises, the material surface on the placement table 40 can come into contact with the processing tools (rotary wheel 11, polishing wheel 12 and wiping disc 13), and the distance between the placement table 40 and the lifting plate 39 will be shortened. The third column spring 38 is in a compressed state, ensuring that the processing tool has a certain pressure on the material and ensuring that the processing is carried out effectively.

[0082] As another embodiment of the present invention, a polishing method for steel structure materials is also proposed, which uses the aforementioned polishing equipment and includes the following steps:

[0083] Step 1: Fix the steel structure material onto the placement platform 40;

[0084] Step two: The thread drive mechanism drives the first horizontal plate 3 to make the first lateral movement, and the rotating wheel 11 applies polishing agent to the material surface.

[0085] Step 3: The elastic transmission mechanism is triggered, driving the mounting bracket 4 to rotate. The threaded drive mechanism drives the first horizontal plate 3 to perform a second lateral movement. The polishing wheel 12 polishes the material surface.

[0086] Step four: The elastic transmission mechanism is triggered, causing the mounting bracket 4 to rotate again, and the threaded drive mechanism drives the first horizontal plate 3 to make a third lateral movement, and the wiping disc 13 wipes and cleans the material surface.

[0087] Step 5: Remove the steel structure material from the platform 40 to complete the processing.

[0088] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0089] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
