Description

Technical Field

[0001] This utility model relates to the field of polishing equipment technology, and more specifically, to a surface polishing equipment for processing rail transit vehicles. Background Technology

[0002] Surface grinding equipment for rail transit vehicles is a specialized piece of equipment designed for treating the surfaces of vehicle components. Its core function is to improve the surface quality of components through grinding processes, meeting the stringent safety and reliability requirements of rail transit vehicles. The working principle of surface grinding equipment is mainly based on the high-speed rotation or reciprocating motion of the grinding head, which drives the grinding wheel to contact the workpiece surface. The grinding action of the grinding wheel removes burrs, oxide scale, weld excess, and wear layers from the workpiece surface, thereby improving surface roughness, flatness, and smoothness. In automated equipment, sensors monitor the grinding status in real time and feed the data back to the control system so that grinding parameters can be adjusted in a timely manner to ensure grinding quality. Since the workpiece is moved by the conveyor belt during grinding, the unloading of the workpiece directly affects the grinding efficiency; therefore, it is necessary to perform a grinding unloading operation.

[0003] In related technologies, during the use of surface grinding equipment, workers typically place the workpieces that need to be ground on the surface of the conveyor belt, so that the conveyor belt can move the workpieces into the grinding equipment for grinding.

[0004] However, in the current use of surface grinding equipment, the process of feeding workpieces requires workers to repeatedly pick them up and place them on the conveyor belt, which makes the workpiece feeding process cumbersome and inefficient, affecting the convenience and efficiency of the grinding equipment.

Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0030] Reference Figures 1-4This utility model provides a technical solution: a surface grinding equipment for processing rail transit vehicles, including a grinding machine 1 and a grinding and feeding mechanism. The grinding machine 1 has an operating table 2 installed at the bottom of its front side, and a conveyor belt 3 installed at the top inside the operating table 2. This can form a medium for accommodating and feeding materials on the top of the operating table 2, so that the user can place external workpieces on the surface of the conveyor belt 3 for grinding and feeding operations. This avoids the cumbersome feeding operation when using the operating table 2 and the conveyor belt 3, thus improving the convenience and efficiency of grinding and feeding of the operating table 2 and the conveyor belt 3.

[0031] Reference Figures 1-4 In a preferred embodiment, the grinding and feeding mechanism includes a feeding frame 4, which is movably connected to the top of the operating table 2. A feeding plate 5 is movably connected inside the feeding frame 4. A discharge port 6 is located at the bottom rear side of the feeding frame 4. A support frame 7 is fixedly connected to the bottom outer side of the feeding frame 4. A feeding stabilizing mechanism is located at the bottom of the support frame 7. External workpieces are placed inside the feeding frame 4 and the feeding plate 5. As the conveyor belt 3 moves, the bottommost workpiece follows the conveyor belt 3 through the discharge port 6, moves out of the feeding frame 4, and enters the grinding machine 1. During the grinding process, the top workpiece moves downwards under the influence of gravity and contacts the conveyor belt 3, thus cyclically grinding and feeding. The feeding stabilizing mechanism includes a screw hole 8, a stud 9, and a stabilizing plate 10. The screw hole 8 is located at the bottom of the support frame 7, the stud 9 is threaded into the interior of the screw hole 8, and the stabilizing plate 10 is fixedly connected to the top of the stud 9. The support frame 7 can stabilize the feeding work between the feeding frame 4 and the operating table 2, preventing the feeding frame 4 from shifting position or becoming unstable during operation, thereby improving the working stability of the feeding frame 4.

[0032] Reference Figures 2-3 In a preferred embodiment, an adjustment groove 11 is provided at the top of the inner wall of the discharge port 6. An adjustment plate 12 is magnetically connected inside the adjustment groove 11. An movable opening 13 is provided on the outer side of the inner wall of the adjustment groove 11. This provides a medium for users to adjust the discharge size of the discharge port, avoiding the situation where the discharge size is difficult to adjust when using the discharge port. Therefore, the flexibility of the discharge port is improved. Threaded grooves 14 are provided at the top of both sides of the adjustment plate 12 and are connected to the movable opening 13. Bolts 15 located on the outer side of the discharge frame 4 are threaded inside the threaded grooves 14. This provides a medium for users to stabilize the positioning between the adjustment plate 12 and the discharge frame 4. Therefore, the convenience of adjusting and positioning the adjustment plate 12 is improved.

[0033] Reference Figures 2-4In a preferred embodiment, by providing sliding openings 16 on the top of both sides of the feeding plate 5, and the top of the feeding frame 4 being located inside the sliding openings 16, the feeding plate 5 and the feeding frame 4 can be slidably guided, preventing the feeding plate 5 from shifting position during use, thus improving the stability of the feeding plate 5. Positioning grooves 17 are provided on both sides of the top of the feeding frame 4, and a positioning frame 18 is movably connected to the top of the feeding plate 5, passing through the sliding openings 16 and located inside the positioning grooves 17, which can provide the user with a medium for positioning the feeding plate 5 and the feeding frame 4, thus improving the convenience of positioning the feeding plate 5 and the feeding frame 4.

[0034] Reference Figures 2-4 In a preferred embodiment, a lifting groove 19 is provided on the top of the feeding plate 5, and a lifting plate 20 located inside the lifting groove 19 is fixedly connected to the bottom of the positioning frame 18. This allows for lifting and lowering connection between the positioning frame 18 and the feeding plate 5, thus improving the connection effect between the positioning frame 18 and the feeding plate 5. Magnetic strips 21 are embedded on both sides of the lifting plate 20, and magnetic strips 22 that are magnetically connected to the magnetic strips 21 are embedded on both sides of the inner wall of the lifting groove 19. The lifting plate 20 can be used to magnetically position the positioning frame 18 and the feeding plate 5 after lifting and moving, thus improving the ease of operation of the positioning frame 18.

[0035] Specifically, the working process or working principle of this surface grinding equipment for rail transit vehicle processing is as follows: During use, the feeding frame 4 is moved to the top of the operating table 2, and the support frame 7 is positioned at the bottom of the operating table 2. Then, the stud 9 is held and rotated to engage the screw hole 8, applying an upward threaded force to the stabilizing plate 10, causing the stabilizing plate 10 to contact and press firmly against the bottom of the operating table 2. This ensures the stable contact between the feeding frame 4 and the operating table 2. Subsequently, based on the actual thickness of a single vehicle workpiece, the adjusting plate 12 is moved within the adjusting groove 11 by using bolts 15 to engage the screw groove 14 and the movable opening 13. The material is moved to adjust the feeding size of the feeding port. After the adjusting plate 12 moves, the bolt 15 is rotated to engage with the screw groove 14 to tighten the threads between the adjusting plate 12 and the feeding frame 4 for stability. Then, the external workpiece is placed on top of the conveyor belt 3, and the workpiece is brought into contact with the rear side of the inner wall of the feeding frame 4. The feeding plate 5 is then moved to the inner side of the feeding frame 4. At this time, the sliding port 16 moves to the top of the feeding frame 4 to slide the feeding plate 5 and the feeding frame 4. The feeding plate 5 is then moved to contact the front side of the workpiece to limit its movement. Finally, the pressure is pressed down. Positioning frame 18 is inserted into positioning groove 17 to perform insertion and positioning work between placement plate and placement frame. At this time, lifting plate 20 moves with positioning frame 18 inside lifting groove 19 to perform lifting and anti-displacement work between positioning frame 18 and feeding plate 5. At the same time, magnetic strip 21 and magnetic suction strip 22 perform magnetic suction positioning work between positioning frame 18 and placement plate through lifting plate 20. When conveyor belt 3 is working, the bottom of the workpiece stack inside the feeding frame 4 and feeding plate 5 is affected by the moving force of conveyor belt 3 and moves with conveyor belt 3 to the discharge. The workpiece stack is moved out of the discharge frame 4 and enters the grinding machine 1 for grinding. During this process, the adjustment plate 12 works with the discharge frame 4 and the discharge plate 5 to restrict and stabilize the workpiece stack. As the bottom workpiece moves out of the discharge frame 4 with the conveyor belt 3, the workpiece stack inside the discharge frame 4 moves downward under the influence of gravity and comes into contact with the conveyor belt 3 so that the conveyor belt 3 can transport the workpiece at the bottom of the workpiece stack. This cycle is repeated to grind and discharge the workpieces that need to be ground. Since the discharge plate 5 is made of transparent acrylic, the staff can observe the workpiece discharge in real time through the discharge plate 5.

[0036] It should be noted that the grinding machine 1, the operating table 2 and the conveyor belt 3 are all existing devices or equipment, or devices or equipment that can be implemented with existing technology. Their power supply, specific composition and principle are clear to those skilled in the art, so they will not be described in detail.
