Description

Technical Field

[0001] This utility model belongs to the field of steel plate production and processing technology, specifically, it relates to a double-sided steel plate grinding machine. Background Technology

[0002] The prior art discloses a double-sided steel plate grinding machine (application number 202320709342.5), which includes two vertical plates; a worktable is provided between the two vertical plates, and a rotating shaft is rotatably installed above and below the worktable. The two ends of the rotating shaft are rotatably connected to the two vertical plates respectively; a grinding disc is fixedly installed on the outer wall of the rotating shaft, and an mounting plate is fixedly installed on the outer wall of the vertical plate below the rotating shaft.

[0003] The aforementioned existing technology involves passing the steel plate through two grinding discs, one above the other, and then grinding the steel plate by the rotation of the grinding discs. While the rotating grinding discs can indeed grind the steel plate to a certain extent, there are still some blind spots in the grinding process. Furthermore, it cannot be guaranteed that the steel plate will be completely ground as it passes through the two grinding discs. If there are severe rust spots in some areas, multiple back-and-forth grinding processes are required to clean them.

[0004] In view of this, this utility model is proposed. Utility Model Content

[0005] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by this utility model is as follows:

[0006] A double-sided steel plate grinding machine includes a worktable, which is U-shaped. The two side walls of the top of the worktable are horizontally extended. Support legs are fixedly welded to the bottom of the two horizontally extended side walls of the worktable. Movable plates are movably arranged in the two side cavities of the worktable. Grinding components for reciprocating extrusion grinding of both sides of the steel plate are provided on the side wall of the two moving plates that are close to each other. A reciprocating structure is provided between the moving plates and the corresponding side outer wall of the worktable, and the reciprocating structure drives the moving plates to move.

[0007] In a preferred embodiment of this utility model, the bottom wall of the workbench is provided with a hollow rectangular groove, and a filter plate is provided in the rectangular groove. The filter plate is fixedly welded to the wall of the workbench. Below the filter plate, a collection box for collecting grinding debris is also provided, and the collection box is fixedly welded to the bottom wall of the workbench.

[0008] In a preferred embodiment of this utility model, the motion plate is L-shaped, with its vertical end located inside the cavity of the workbench and its horizontal end attached to the horizontal wall of the workbench. Guide slide plates are also fixedly welded to the top walls of the horizontal ends of both motion plates. The guide slide plates are L-shaped, and guide grooves are respectively provided on the two side walls of the top of the workbench to engage with the corresponding guide slide plates. The guide slide plates engage with the guide grooves to guide and limit the motion plates.

[0009] In a preferred embodiment of the present invention, the reciprocating structure includes a servo motor fixedly mounted on the side wall of the workbench via a bracket. The output end of the servo motor is fixedly connected to a turntable. A first column is fixedly welded to one outer wall of the turntable. A second movable sleeve is rotatably fitted onto the outer wall of the first column. Through slots are provided on both outer walls of the workbench, and the through slots penetrate the side walls of the workbench.

[0010] In a preferred embodiment of this utility model, connecting columns are fixedly welded to the outer wall of the motion plate. The connecting columns extend outward through through slots. A second column is fixedly welded to the outer wall of the connecting column. A third movable sleeve is rotatably fitted onto the outer wall of the second column. A connecting rod is also movably installed between the third movable sleeve and the second movable sleeve.

[0011] In a preferred embodiment of the present invention, the polishing assembly includes a polishing plate, and multiple sets of telescopic rods are fixedly installed between the inner wall of the polishing plate and the moving plate. A polishing layer is also fixedly installed on the side wall of the polishing plates on both sides that are close to each other.

[0012] In a preferred embodiment of this utility model, electromagnets are fixedly installed on the inner walls of the two moving plates that are close to each other, and permanent magnets are fixedly installed on the side walls of the grinding plates that are far apart from each other. The permanent magnets on each side correspond to the positions of the electromagnets on each side, and the electromagnets have the same magnetic poles as the permanent magnets when energized.

[0013] Compared with the prior art, the present invention has the following advantages:

[0014] 1. This solution uses a set of motion plates, reciprocating structure and grinding components. The two relatively moving motion plates drive their respective grinding components to perform reciprocating friction motion on the clamped steel plate, which can realize reciprocating extrusion grinding of the steel plate and improve the automatic grinding efficiency of both sides of the steel plate.

[0015] 2. Through the grinding components set up in this solution, the magnetic force generated by the electromagnet on the permanent magnet on the grinding plate can not only enable the grinding plate and the grinding layer to rub and clamp the two sides of the steel plate, thereby increasing the friction during steel plate grinding, but also enable friction grinding of steel plates of different thicknesses, further improving the practicality of this solution.

[0016] 3. Compared with existing technologies, this solution solves the problem of blind spots in grinding. When the steel plate is ground on both sides, it is completely located between the grinding layers on both sides. The constantly reciprocating grinding layers can achieve continuous friction and grinding of the steel plate. Compared with existing technologies, it increases the grinding area and grinding efficiency. Even if it is not cleaned in one go, the steel plate can be fully ground through continuous movement.

[0017] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings. Attached Figure Description

[0025] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate this utility model.

[0026] A double-sided steel plate grinding machine, such as Figure 1As shown, the workbench 10 is U-shaped. The two side walls of the top of the workbench 10 are horizontally extended. Support legs 15 are fixedly welded to the bottom of the two horizontally extended side walls of the workbench 10. Motion plates 16 are movably arranged in the two side cavities of the workbench 10. Grinding components for reciprocating extrusion grinding of the two sides of the steel plate are provided on the side wall of the two motion plates 16 that are close to each other. Reciprocating structures 20 are provided between the motion plates 16 and the corresponding side outer wall of the workbench 10. The reciprocating structures 20 drive the motion plates 16 to move.

[0027] like Figure 1 , Figure 2 and Figure 3 As shown, the bottom wall of the workbench 10 has a hollowed-out rectangular groove, in which a filter plate 11 is installed. The filter plate 11 is fixedly welded to the wall of the workbench 10. Below the filter plate 11, a collection box 12 for collecting grinding debris is also provided, and the collection box 12 is fixedly welded to the bottom wall of the workbench 10. The moving plate 16 is L-shaped, with its vertical end located inside the cavity of the workbench 10 and its horizontal end attached to the horizontal wall of the workbench 10. Guide slide plates 13 are fixedly welded to the top walls of the horizontal ends of both moving plates 16. The guide slide plates 13 are L-shaped, and guide grooves 14 are respectively opened on the two side walls of the top of the workbench 10 to movably engage with the corresponding guide slide plates 13. The guide slide plates 13 movably engage in the guide grooves 14 to guide and limit the moving plates 16.

[0028] like Figure 2 , Figure 4 As shown, the reciprocating structure 20 includes a servo motor 21 fixedly mounted on the side wall of the worktable 10 via a bracket. A turntable 22 is fixedly connected to the output end of the servo motor 21. A first column 23 is fixedly welded to one outer wall of the turntable 22. A second movable sleeve 24 is rotatably fitted onto the outer wall of the first column 23. Through slots 29 are provided on both outer walls of the worktable 10, penetrating the side walls of the worktable 10. Connecting columns 26 are fixedly welded to the outer wall of the motion plate 16. The connecting columns 26 extend outwards through the through slots 29. A second column 27 is fixedly welded to the outer wall of the connecting column 26. A third movable sleeve 28 is rotatably fitted onto the outer wall of the second column 27. A connecting rod 25 is also movably installed between the third movable sleeve 28 and the second movable sleeve 24.

[0029] like Figure 3 and Figure 5As shown, the polishing assembly includes a polishing plate 32. Multiple sets of telescopic rods 30 are fixedly installed between the polishing plate 32 and the inner wall of the moving plate 16. A polishing layer 33 is also fixedly installed on the side wall of the polishing plates 32 that are close to each other. Electromagnets 31 are fixedly installed on the inner walls of the two moving plates 16 that are close to each other. Permanent magnets 34 are fixedly installed on the side wall of the polishing plates 32 that are far apart from each other. The position of each permanent magnet 34 corresponds to that of each electromagnet 31. When the electromagnet 31 is energized, its magnetic poles are the same as those of the permanent magnet 34.

[0030] When in use, place the steel plate that needs to be polished on both sides in the workbench 10, that is, between the two polishing layers 33. Turn on the electromagnets 31 on both sides. The electromagnets 31 generate magnetic force after being turned on. The electromagnets 31 generate magnetic repulsion on the permanent magnets 34, which causes the polishing plate 32 to move the polishing layers 33 away from the moving plate 16. In this way, the polishing layers 33 on both sides clamp the steel plate.

[0031] Then, turn on the servo motor 21. After the servo motor 21 is powered on, it starts working and drives the turntable 22 to rotate. The turntable 22 then drives the first column 23 to rotate. When the first column 23 rotates away from the connecting column 26, the first column 23 drives the second column 27 to move the connecting column 26 through the second movable sleeve 24 and the connecting rod 25. The connecting column 26 then drives the corresponding moving plate 16 to move. The movement of the moving plate 16 drives the grinding assembly to rub and grind the clamped steel plate. When the turntable 22 drives... When the first column 23 moves towards the side closer to the connecting column 26, the connecting rod 25 pushes the second column 27 and the connecting column 26. The connecting column 26 then drives the moving plate 16 to the other side, thus enabling the moving plate 16 to reciprocate horizontally within the worktable 10. The two moving plates 16 synchronously drive the grinding assembly to rub and grind the steel plate, thereby continuously grinding both sides of the steel plate. The debris and dirt generated during grinding can fall down through the filter plate 11 and finally fall into the collection box 12 for collection.

[0032] It is worth noting that the two moving plates 16 move in opposite directions. For example, when one moving plate 16 moves forward, the other moving plate 16 moves backward, forming an interlaced pattern, which can improve the grinding efficiency of the steel plate.

[0033] After grinding the steel plate for a certain period of time, first disconnect the switches of the two servo motors 21, and then disconnect the power switches of the electromagnets 31 on both sides. At this time, the grinding plates 32 on both sides no longer clamp the steel plate, and the ground steel plate can be taken out from the worktable 10 cavity.

[0034] It is understood that this utility model has been described through some embodiments, and those skilled in the art will recognize that various changes or equivalent substitutions can be made to these features and embodiments without departing from the spirit and scope of this utility model. Furthermore, under the teachings of this utility model, these features and embodiments can be modified to adapt to specific situations and materials without departing from the spirit and scope of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed herein, and all embodiments falling within the scope of the claims of this application are within the protection scope of this utility model.
