Description

Technical Field

[0001] This utility model relates to the field of grinding equipment, and in particular to a grinding equipment for liners used in cast iron trenches. Background Technology

[0002] Cast iron troughs are extremely common in industrial production, widely used in steel mills, foundries, and other places as channels for transporting liquid or molten metal. A corresponding liner is installed at the top of the cast iron trough. The liner is typically designed to prevent direct erosion damage to the trough body from the high-temperature metal flow. During the liner manufacturing process, its surface must be precision ground to meet usage requirements.

[0003] A Chinese patent application (CN202322555435.X) discloses a liner processing and grinding device, comprising a grinding table. Two clamping plates are slidably fitted on the upper side of the grinding table, with a liner placed between the clamping plates. Two grinding frames are slidably fitted on the grinding table, located on opposite sides of the liner. Sliding blocks are slidably fitted within each grinding frame, and each sliding block contains a rotating locking block and an insert block. A grinding roller and a pressure rod are installed between the two sliding blocks, with the two ends of the grinding roller corresponding to the rotating locking block and the insert block, respectively. In this invention, sliding blocks are installed within the grinding frames, and a second electric cylinder drives the sliding blocks up and down, thereby driving the grinding roller to slide. The pressure rod controls the position of the grinding roller, allowing for grinding of liners with different curvatures, thus preventing uneven grinding. Clamping plates are installed on the grinding table, and sliding these plates hold and fix the liner, preventing it from moving during grinding.

[0004] However, the above-mentioned patent has certain defects in use. Because it cannot effectively adapt to different sizes of liners during the grinding process, it leads to frequent tooling changes, which affects processing efficiency. In addition, the clamping is unstable after the liner is placed in the grinding process, which is prone to displacement and affects grinding accuracy.

[0005] To address these issues, a grinding device for cast iron trench liners is proposed. Utility Model Content

All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0017] Example: Please see Figures 1-5A grinding device for liners in cast iron trenches includes a worktable 1 and a tray 22. The tray 22 is located above the worktable 1, and a liner 7 is placed on the tray 22. A first slide 11 is provided on the top of the worktable 1. A first motor 2 is provided on one side of the first slide 11. The output end of the first motor 2 is located inside the first slide 11 and is movably connected to a first lead screw 21. The tray 22 is movably connected to the first lead screw 21. The tray 22 has a displacement groove 50 inside, and a fourth motor 5 is provided on one side of the tray 22. The output end of the fourth motor 5 is located inside the displacement groove 50 and is provided with a screw 51. A movable groove 6 is symmetrically provided on the top of the tray 22. A movable plate 61 is provided in the movable groove 6. Second springs 62 are symmetrically provided on both sides of the movable plate 61. The ends of the second springs 62 abut against the inner wall of the movable groove 6.

[0018] In this embodiment, a first slide 11 is provided on the top of the workbench 1. A first motor 2 is provided on one side of the first slide 11. A first lead screw 21 is movably connected to the output end of the first motor 2. The first lead screw 21 is located inside the first slide 11 and is threadedly engaged with it, driving the tray 22 to move along the axial direction of the slide, so as to realize the smooth sliding of the tray 22 on the workbench 1. A displacement groove 50 is provided in the middle of the tray 22. A screw 51 is provided in the displacement groove 50. The screw 51 is driven by a fourth motor 5. The fourth motor 5 is fixed on the side wall of the tray 22. An movable groove 6 is located on the top of the tray 22. There are two movable grooves 6. The two movable grooves 6 are symmetrically distributed with the displacement groove 50 as the center. A movable plate 61 is embedded in the movable groove 6. A second spring 62 is provided in the part of the movable plate 61 located in the movable groove 6. Multiple second springs 62 are provided and symmetrically arranged between the two sides of the movable plate 61 and the inner wall of the movable groove 6, so as to ensure that the movable plate 61 can elastically expand and contract when subjected to external force, and firmly clamp the liner 7 above the tray 22.

[0019] Positioning plate 52, two of them are provided, one of which is bolted to the top of the tray 22, and the other is movably connected to the screw 51. The liner 7 is clamped between the positioning plate 52 and the movable plate 61.

[0020] In this embodiment, there are two positioning plates 52, which are symmetrically arranged with two movable plates 61 on both sides of the displacement groove 50. The two positioning plates 52 and the two movable plates 61 form a symmetrical clamping structure to stabilize and limit the edge of the liner 7. One of the two positioning plates 52 is fixed to the top of the tray 22, and the other is threadedly connected to the screw 51. When the fourth motor 5 drives the screw 51 to rotate, the positioning plate 52 moves horizontally along the direction of the displacement groove 50 as the screw 51 rotates. That is, the movable plate 61, which is movably connected to the screw 51, is displaced and moves closer to or away from the positioning plate 52 fixed on the tray 22, thereby adjusting the distance between the two positioning plates 52. The function of the movable plate 61 is to realize the adaptive clamping of liners 7 of different sizes. Through the elastic action of the second spring 62, the movable plate 61 maintains a stable clamping force during movement. The positioning plates 52 and the movable plate 61 work together to adapt to the clamping requirements of liners 7 of different sizes, realize rapid positioning and fixing, and improve processing stability and work efficiency.

[0021] Specifically, the workbench 1 has a support frame 12 at its bottom, which is located directly above the first slide table 11. A second slide table 13 is mounted on the support frame 12. A second motor 3 is mounted on one side of the second slide table 13. The output end of the second motor 3 is connected to a second lead screw 31. A sliding plate 32 is movably connected to the second lead screw 31. A third slide table 14 is mounted on the sliding plate 32. A third motor 4 is mounted on one side of the third slide table 14. The output end of the third motor 4 is connected to a third lead screw 41. A grinding machine 42 is movably connected to the third lead screw 41. A grinding head 43 is mounted on the output end of the grinding machine 42.

[0022] In this embodiment, the support frame 12 has an inverted C-shaped structure and is located directly above the first slide table 11. A second slide table 13 is installed on the support frame 12, and the second slide table 13 is located directly above the first slide table 11. The second slide table 13 is arranged in a horizontal longitudinal direction, and the range of motion of the second slide table 13 covers the entire stroke of the first slide table 11, ensuring that the moving plate 32 can move horizontally within the full range. A second motor 3 is provided on one side of the second slide table 13, and a second lead screw 31 is movably connected to the output end of the second motor 3. The second lead screw 31 is located within the range of motion of the second slide table 13, and the moving plate 32 is movably connected to the second lead screw 31. The moving plate 32 can move horizontally along the second lead screw 31 under the drive of the second motor 3.

[0023] A third slide 14 is vertically mounted on the sliding plate 32, and the third slide 14 is arranged perpendicularly to the second slide 13. A third motor 4 is provided on one side of the third slide 14, and the output end of the third motor 4 is connected to a third lead screw 41, which is located within the range of motion of the third slide 14. A grinding machine 42 is movably connected to the third lead screw 41. The grinding machine 42 can move vertically up and down along the third lead screw 41 under the drive of the third motor 4, thereby precisely adjusting the grinding height. By combining the coordinated control of the first slide 11, the second slide 13, and the third slide 14, the grinding machine 42 can be accurately positioned in three-dimensional space to meet the grinding needs of the liner 7 at different positions and depths.

[0024] Specifically, the moving plate 32 is provided with an air nozzle 44 located next to the grinder 42.

[0025] In this embodiment, the jet nozzle 44 is connected to an external air source. When the grinding machine 42 drives the grinding head 43 to grind the liner plate 7, the jet nozzle 44 simultaneously sprays high-pressure gas into the grinding area to effectively remove grinding debris and dust, keep the working surface clean, and avoid the accumulation of impurities that affect the grinding accuracy.

[0026] Specifically, the positioning plate 52 is provided with a plurality of first springs 521 on its inner side, and the ends of the plurality of first springs 521 are connected to contact plates 522.

[0027] In this embodiment, two positioning plates 52 are provided. On the opposite side of the two positioning plates 52, that is, on the inner side of the positioning plates 52, multiple first springs 521 are provided. The ends of the multiple first springs 521 are connected to contact plates 522. When the movable plate 61 connected to the screw 51 moves toward the positioning plate 52 fixed on the tray 22, the contact plate 522 contacts the surface of the liner 7 first under the elastic force of the first springs 521. As the movable plate 61 continues to move, the first springs 521 are compressed, thereby firmly clamping the liner 7 between the two positioning plates 52 through the elastic preload.

[0028] Specifically, the inner wall of the movable plate 61 is provided with anti-slip pads 611.

[0029] In this embodiment, the anti-slip sticker 611 on the inner side of the movable plate 61 is used to enhance the friction during the clamping process of the liner 7. The anti-slip sticker 611 is made of silicone or rubber.

[0030] The principle of this utility model is as follows: First, the liner 7 is placed on top of the tray 22. The movable plate 61 clamps the liner 7 between the two positioning plates 52 under the clamping action of the second spring 62. There are two positioning plates 52. The distance between the two positioning plates 52 can be finely adjusted by the second spring 62 to achieve adaptive clamping for liner 7 of different sizes. Then, the fourth motor 5 drives the screw 51 to rotate, which drives the movable plate 61 to move along the displacement groove 50. When the movable plate 61 connected to the screw 51 moves towards the positioning plate 52 fixed on the tray 22, the contact plate 522 contacts the surface of the liner 7 first under the elastic force of the first spring 521. As the movable plate 61 continues to move, the first spring 521 is compressed, thereby firmly clamping the liner 7 between the two positioning plates 52 through the elastic preload. At this time, the liner 7 is fixed.

[0031] Subsequently, the first motor 2 drives the first lead screw 21 to rotate, causing the first slide 11 to move laterally along the guide rail. At the same time, the second motor 3 drives the second lead screw 31 to rotate, adjusting the longitudinal position of the second slide 13. The third motor 4 synchronously controls the grinding machine 42 to rise and fall. By combining the coordinated control of the first slide 11, the second slide 13 and the third slide 14, the grinding machine 42 can be accurately positioned in three-dimensional space to meet the grinding needs of the liner 7 at different positions and depths.

[0032] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model based on the technical solution and its improved concept should be covered within the protection scope of the present utility model.
