[0004] However, in the aforementioned patents, the position of the grinding wheel cannot be moved, and the grinding area cannot be changed horizontally to cover different positions of the track plate. In actual processing, if track plates of different specifications or different areas need to be ground, it is necessary to manually disassemble and reposition the track plates repeatedly, or even replace the grinding frame components. The operation is cumbersome and time-consuming. Based on this, this utility model designs a surface grinding device for track plate processing to solve the above problems. Utility Model Content

[0005] In view of the above-mentioned shortcomings of the existing technology, the present invention provides a surface grinding device for processing track plates.

[0006] To achieve the above objectives, this utility model provides the following technical solution: A surface grinding device for processing track plates includes a base, a mounting frame fixedly connected to the top of the base, a first threaded rod rotatably connected inside the mounting frame, a fixed frame threadedly connected to the outer wall of the first threaded rod, the fixed frame and the mounting frame being slidably connected, a second threaded rod rotatably connected inside the fixed frame, a moving block threadedly connected to the outer wall of the second threaded rod, the moving block and the fixed frame being slidably connected, a hydraulic cylinder fixedly connected below the moving block, a third motor fixedly connected to the output end of the hydraulic cylinder, and a grinding wheel fixedly connected to the output end of the third motor.

Bolts are threadedly connected to the lower sides of both sides of the base, and clamping plates are rotatably connected to one end of each bolt located inside the base. The clamping plates are slidably connected to the base.

[0008] Furthermore, a second motor is fixedly connected to the outside of the fixed frame, and the output end of the second motor is fixedly connected to one end of the second threaded rod.

[0009] Furthermore, the base has sliding grooves on both sides, and a rotating shaft is slidably connected inside the sliding grooves. Two racks are fixedly connected to both sides of the base, with the racks located below the sliding grooves respectively.

[0010] Furthermore, gears are fixedly connected to both ends of the rotating shaft, and the two gears mesh with two racks respectively.

[0011] Furthermore, a brush roller is fixedly connected to the outside of the rotating shaft, a No. 3 threaded rod is rotatably connected to the outside of the base, a fixing block is threadedly connected to the outer wall of the No. 3 threaded rod, the fixing block and the rotating shaft are rotatably connected to the outer wall of the base, the fixing block and the outside of the base are slidably connected, a No. 4 motor is fixedly connected to the outside of the base, and the output end of the No. 4 motor is fixedly connected to one end of the No. 3 threaded rod.

[0014] In this invention, the horizontal cross adjustment structure can stably drive the grinding wheel to move along the X and Z axes of the mounting frame, allowing grinding of any position on the track plate. It can also adjust the horizontal trajectory of the grinding wheel to grind special areas such as the edges and grooves of the track plate, avoiding the problems of uneven grinding and local missed grinding in traditional devices, and ensuring consistent grinding of all areas on the track plate surface.

[0015] In this invention, the brush roller operates synchronously with the rotating shaft through "sliding + rotation", which can initially remove most of the debris from the surface of the track plate; at the same time, the gear generates compressed air through the turntable and connecting rod, which is sprayed out from the air nozzle through the duct and air pipe, which can perform secondary cleaning on the surface of the track plate and blow away the fine debris that the brush roller cannot remove.

[0020] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0021] The present invention will be further described below with reference to the embodiments.

[0022] In some embodiments, please refer to Figures 1-5A surface grinding device for processing track plates includes a base 1, a mounting frame 11 fixedly connected to the top of the base 1, a first threaded rod 12 rotatably connected inside the mounting frame 11, a fixed frame 14 threadedly connected to the outer wall of the first threaded rod 12, the fixed frame 14 and the mounting frame 11 being slidably connected, a second threaded rod 15 rotatably connected inside the fixed frame 14, a moving block 17 threadedly connected to the outer wall of the second threaded rod 15, the moving block 17 and the fixed frame 14 being slidably connected, a hydraulic cylinder 18 fixedly connected below the moving block 17, and the output end of the hydraulic cylinder 18... A No. 3 motor 19 is fixedly connected, and a grinding wheel 2 is fixedly connected to the output end of the No. 3 motor 19. A No. 1 motor 13 is fixedly connected to the top of the mounting bracket 11. The output end of the No. 1 motor 13 is fixedly connected to one end of the No. 1 threaded rod 12. Bolts 21 are threadedly connected to the lower sides of both sides of the base 1. The two bolts 21 are rotatably connected to a clamping plate 22 at one end inside the base 1. The clamping plate 22 is slidably connected to the base 1. A No. 2 motor 16 is fixedly connected to the outside of the fixing frame 14. The output end of the No. 2 motor 16 is fixedly connected to one end of the No. 2 threaded rod 15.

[0023] In this embodiment, the device drives the fixed frame 14 to slide stably along the mounting frame 11 through the transmission structure of "motor 13-threaded rod 12-fixed frame 14". This enables the grinding wheel 2 to make a wide range of uniform position adjustments in the horizontal direction, which can quickly adapt to the processing requirements of track plates of different thicknesses. This avoids the tedious operation of repeated manual disassembly and adjustment required by traditional devices, and greatly shortens the pre-processing time. With the horizontal adjustment mechanism of "Motor No. 2 16 - Threaded Rod No. 2 15 - Moving Block 17", the Moving Block 17 slides within the Fixed Frame 14 without offset or jamming, and can precisely control the movement trajectory of the Grinding Wheel 2 in the horizontal direction. It can target and grind special parts such as edges and grooves on different areas of the track plate surface, solving the problems of "uneven grinding and local missed grinding" that are easy to occur in traditional grinding devices, and significantly improving the surface roughness of the track plate to meet the standard. The hydraulic cylinder 18 can adjust the downward pressure of the grinding wheel 2 on the track plate in real time. It can flexibly adjust the grinding force according to the material of the track plate, such as high-strength steel or alloy, to avoid deformation of the track plate due to excessive pressure. It can also ensure stable pressure and prevent uneven grinding depth due to pressure fluctuations, thus further ensuring the flatness and consistency of the ground surface. The clamping structure composed of bolts 21 on both sides of the base 1 and clamping plate 22 can drive the clamping plate 22 to slide along the base 1 by rotating the bolts 21, which can effectively clamp the track plate.

[0024] In some embodiments, please refer to Figures 1-5A surface grinding device for processing track plates includes a base 1 with grooves 23 on both sides. A rotating shaft 25 is slidably connected inside the grooves 23. Two racks 24 are fixedly connected to both sides of the base 1, each located below a groove 23. Gears 27 are fixedly connected to both ends of the rotating shaft 25, meshing with the two racks 24 respectively. A brush roller 26 is fixedly connected to the outside of the rotating shaft 25. A No. 3 threaded rod 34 is rotatably connected to the outside of the base 1. A fixing block 250 is threaded to the outer wall of the No. 3 threaded rod 34. The fixing block 250 and the rotating shaft 25 are rotatably connected to the outer wall of the base 1. The fixing block 250 and the outer wall of the base 1 are slidably connected. Next, a No. 4 motor 35 is fixedly connected to the outside of the base 1. The output end of the No. 4 motor 35 is fixedly connected to one end of the No. 3 threaded rod 34. One end of a gear 27 is fixedly connected to a turntable 28. A connecting rod 29 is rotatably connected to one side of the turntable 28. An air cylinder 3 is fixedly connected to one side of the fixing block 250. The end of the connecting rod 29 away from the turntable 28 is rotatably connected to the piston end of the air cylinder 3. A conduit 31 is fixedly connected to the output end of the air cylinder 3. One end of the conduit 31 passes through the slide groove 23 and is fixedly connected to an air pipe 32. The end of the air pipe 32 away from the fixing block 250 is rotatably connected to the end of the rotating shaft 25 away from the fixing block 250. Multiple air nozzles 33 are installed below the air pipe 32.

[0025] In this embodiment, by means of the sliding engagement between the sliding grooves 23 on both sides of the base 1 and the rotating shaft 25, combined with the meshing transmission between the gears 27 and the rack 24 at both ends of the rotating shaft 25, when the rotating shaft 25 moves along the sliding grooves 23, the gears 27 will roll along the rack 24 and drive the rotating shaft 25 to rotate, thereby causing the brush roller 26 outside the rotating shaft 25 to rotate synchronously. The rotating brush roller 26 can thoroughly clean the surface of the track plate after grinding, and can quickly remove the metal debris and dust attached to the surface of the track plate, avoid the accumulation of debris affecting the accuracy of subsequent grinding processes, and at the same time reduce secondary scratches on the surface of the track plate by debris, ensuring the surface quality of the track plate after processing. The air blowing mechanism, consisting of air cylinder 3, conduit 31, air pipe 32 and air nozzle 33, drives the turntable 28 at one end to rotate synchronously when the gear 27 rotates. The turntable 28 pulls the piston end of the air cylinder 3 to reciprocate through the connecting rod 29, so that the air cylinder 3 continuously generates compressed air. The compressed air is delivered to the air pipe 32 through the conduit 31, and then evenly sprayed out through multiple air nozzles 33 below the air pipe 32. On the one hand, it can perform secondary cleaning on the surface of the track plate after the brush roller 26 has been cleaned.

[0026] Working principle: After placing the track plate to be ground on the worktable of the base 1, rotate the bolts 21 on both sides of the base 1. Since the bolts 21 are threaded to the base 1 and the end of the bolt 21 located inside the base 1 is rotatably connected to the clamping plate 22, the rotation of the bolts 21 will be converted into the clamping plate 22 sliding along the base 1 in a straight line. The clamping plates 22 on both sides move synchronously towards the track plate until they are tightly attached to both sides of the track plate, forming a symmetrical clamping and fixing, which restricts the displacement of the track plate during the grinding process and provides a stable workpiece base for subsequent grinding operations. Start the first motor 13 on the top of the mounting frame 11. The output end of the first motor 13 drives the first threaded rod 12 inside the mounting frame 11 to rotate. Since the fixed frame 14 is threadedly connected to the first threaded rod 12 and slidably connected to the mounting frame 11, the rotation of the first threaded rod 12 will drive the fixed frame 14 to slide up and down along the mounting frame 11, thereby driving the moving block 17, hydraulic cylinder 18, third motor 19 and grinding wheel 2 below the fixed frame 14 to move horizontally as a whole, initially adjusting the vertical distance between the grinding wheel 2 and the surface of the track plate to match the thickness specification of the track plate. Start the second motor 16 outside the fixed frame 14. The output end of the second motor 16 drives the second threaded rod 15 inside the fixed frame 14 to rotate. Since the moving block 17 is threadedly connected to the second threaded rod 15 and slidably connected to the fixed frame 14, the rotation of the second threaded rod 15 will drive the moving block 17 to slide horizontally along the fixed frame 14, further fine-tuning the position of the grinding wheel 2 in the horizontal direction, ensuring that the grinding wheel 2 can accurately align with the area of ​​the track plate that needs to be ground. By controlling the hydraulic cylinder 18 below the moving block 17, the extension and retraction length of the output end of the hydraulic cylinder 18 can be adjusted. The output end of the hydraulic cylinder 18 is fixedly connected to the No. 3 motor 19. Its extension and retraction will directly change the downward pressure of the No. 3 motor 19 and the grinding wheel 2 on the surface of the track plate. Adjust the pressure to a suitable level according to the material of the track plate to avoid excessive pressure causing deformation of the track plate or insufficient pressure affecting the grinding effect. Once the position and pressure of the grinding wheel 2 are adjusted to the correct position, start motor 3 19. The output of motor 3 19 drives the grinding wheel 2 to rotate at high speed. The rotating grinding wheel 2 contacts the surface of the track plate and performs grinding operations on the surface of the track plate. During this process, the level and horizontal position of the grinding wheel 2 can be finely adjusted by restarting motor 1 13 or motor 2 16 to ensure that all areas of the track plate surface can be ground evenly until the preset surface roughness requirements are met. The output end of motor 35 drives the No. 3 threaded rod 34 outside the base 1 to rotate. Since the fixed block 250 is threadedly connected to the No. 3 threaded rod 34 and slidably connected to the outside of the base 1, the rotation of the No. 3 threaded rod 34 will drive the fixed block 250 to slide horizontally along the outside of the base 1. The fixed block 250 is rotatably connected to the rotating shaft 25, which in turn drives the rotating shaft 25 to slide synchronously along the sliding grooves 23 on both sides of the base 1. At the same time, the gears 27 at both ends of the rotating shaft 25 mesh with the racks 24 on both sides of the base 1 below the sliding grooves 23. When the rotating shaft 25 slides, the gears 27 roll along the racks 24 and drive the rotating shaft 25 to rotate. The brush roller 26 outside the rotating shaft 25 rotates with the rotating shaft 25 and rolls and sweeps the grinding debris and dust on the surface of the track plate, peeling most of the debris off the surface of the track plate.

[0027] When gear 27 rotates, the turntable 28 fixed at one end rotates synchronously. The connecting rod 29 connected to one side of the turntable 28 rotates in a circular motion with the rotation of the turntable 28, which in turn pulls the piston end of the air cylinder 3 on one side of the fixed block 250 to reciprocate. The reciprocating motion of the piston of the air cylinder 3 generates compressed air inside the air cylinder 3. The compressed air is delivered through the conduit 31 at the output end of the air cylinder 3 to the air pipe 32 that passes through the slide groove 23, and finally sprayed out evenly through multiple air nozzles 33 below the air pipe 32. The sprayed airflow performs secondary cleaning on the surface of the track plate after the brush roller 26 has cleaned it.

Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
