Description

Technical Field

[0001] This utility model relates to the field of electric tricycle parts processing, and in particular to a grinding device for processing electric tricycles. Background Technology

[0002] Electric tricycle parts require polishing during processing. Polishing provides a smooth, shiny surface, improving the appearance quality of the parts. Burrs and sharp edges generated during machining can be removed by polishing, preventing damage during use. The smoother surface after polishing helps improve the corrosion resistance of the parts, reducing corrosion and oxidation. High-quality polishing can enhance the overall image of the product and increase market competitiveness. Polishing is an important step in metal processing and plays a vital role in improving the overall quality and performance of electric tricycle parts.

[0003] A search revealed Chinese Patent Publication No. CN220806662U, which discloses a polishing device for processing electric tricycle parts. The device places a square tube on a positioning frame and a support plate. By rotating an adjusting wheel, a screw is moved vertically to fix the positioning plate onto the square tube. Then, the positioning frame is pushed from left to right, pushing the square tube into the corresponding pre-drilled slot. Simultaneously, an air pump inflates the air inlet pipe, causing the gas bladder to expand until sandpaper covers the outside of the square tube. As the square tube moves, the sandpaper removes burrs from its outer surface, allowing for simultaneous polishing of all four sides of the tube.

[0004] In the above technical solution, the square tube is positioned by using a positioning frame and a support plate in conjunction with a screw and the positioning plate, and then polished by a polishing component. However, after most of the tube body is polished, the fixed end is difficult to be polished evenly with other areas of the tube body, resulting in inconsistent polishing degree of the square tube. Therefore, a grinding device for processing electric tricycles is proposed to solve the above problem. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a grinding device for processing electric tricycles, which aims to improve the problem that existing grinding devices for processing electric tricycles cannot guarantee uniform polishing of the square tubes in the receiving positioning area, resulting in inconsistent polishing effects.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a grinding device for processing electric tricycles, comprising a worktable, a polishing component and a fixing component on the top of the worktable, a positioning structure on the surface of the worktable, the positioning structure comprising a U-shaped frame, a fixing plate on the top of the U-shaped frame, a sliding rod fixedly connected to the bottom of the fixing plate, a telescopic spring sleeved on the outer wall of the sliding rod, a positioning plate fixedly connected to the bottom end of the telescopic spring, a guide component at the bottom of the positioning plate, and a moving component at the bottom of the U-shaped frame.

[0007] As a further description of the above technical solution:

[0008] The outer wall of the slide rod is slidably connected to the inner wall of the U-shaped frame, and the top end of the telescopic spring is fixedly connected to the inner surface of the U-shaped frame.

[0009] As a further description of the above technical solution:

[0010] The guide assembly includes an installation groove, the inner wall of the positioning plate has a sliding groove, the inner wall of the sliding groove is slidably connected to a slider, the top of the slider is fixedly connected to a connecting rod, the side wall of the slider is rotatably connected to a guide wheel, the surface of the guide wheel is fixedly connected to an inclined block, and the top of the connecting rod is fixedly connected to a limit spring.

[0011] As a further description of the above technical solution:

[0012] The moving component includes a guide rail, a support frame is fixedly connected to the bottom of the guide rail, and a sliding plate is slidably connected to the outer wall of the guide rail.

[0013] As a further description of the above technical solution:

[0014] The mounting groove is formed on the lower surface of the positioning plate, the sliding groove is located inside the mounting groove, and the top end of the limiting spring is fixedly connected to the inner wall of the mounting groove.

[0015] As a further description of the above technical solution:

[0016] The bottom of the guide rail is fixedly connected to the upper surface of the worktable, and the upper surface of the sliding plate is fixedly connected to the lower surface of the U-shaped frame.

[0017] As a further description of the above technical solution:

[0018] A water tank is fixedly connected to the outer wall of the workbench, a connecting hose is fixedly connected to the inner wall of the water tank, a corrugated pipe is fixedly connected to the outer wall of the connecting hose, a strong magnet is fixedly connected to the side wall of the sliding plate, and a strong magnet is fixedly connected to the outer wall of the support frame.

[0019] As a further description of the above technical solution:

[0020] One end of the corrugated pipe is fixedly connected to the outer wall of the workbench, and the other end of the corrugated pipe is fixedly connected to the side wall of the sliding plate.

[0021] This utility model has the following beneficial effects:

[0022] 1. In this utility model, a circular frame, a sliding rod, and a telescopic spring are used to position the square tube in conjunction with a positioning plate. The guide component allows the polished area of ​​the square tube to move inside the circular frame to receive positioning. At the same time, when the square tube generates a reverse displacement force, the friction increases. The moving component facilitates the movement of the square tube so that its very end enters the polishing component to receive polishing, thereby avoiding uneven polishing between the polished very end and the tube body, and ensuring the overall polishing integrity of the tube body.

[0023] 2. In this utility model, water is introduced into the water tank by setting a corrugated pipe and a connecting hose. The repulsive force between the first strong magnet and the second strong magnet makes the U-shaped frame have a buffering force when moving the square tube, avoiding the risk that the end of the square tube will detach from the polishing component due to the large pulling force of the operator, resulting in poor polishing effect.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Reference Figures 1-3 This utility model provides an embodiment of a grinding device for processing electric tricycles, including a worktable 1, a polishing component 2 disposed on the top of the worktable 1, and a fixing component 3 disposed on the top of the worktable 1. The worktable 1, polishing component 2, and fixing component 3 are similar in principle to the worktable, polishing component, and fixing seat mentioned in Chinese Patent No. CN220806662U (A Grinding Device for Processing Electric Tricycle Parts), and achieve the same effect. They are existing disclosed technical means in this field, and will not be described in detail here. The worktable 1... The surface is provided with a positioning structure, which includes a U-shaped frame 7. The U-shaped frame 7 facilitates the insertion of the square tube into it. A fixing plate 8 is provided on the top of the U-shaped frame 7. A sliding rod 9 is fixedly connected to the bottom of the fixing plate 8. There are four sets of sliding rods 9, and the sliding rods 9 are distributed in a rectangular array with the central axis of the U-shaped frame 7 as the axis of symmetry. The number of telescopic springs 10 is the same as that of the sliding rods 9. The outer wall of the sliding rod 9 is fitted with a telescopic spring 10. The bottom end of the telescopic spring 10 is fixedly connected to a positioning plate 11. A guide component is provided at the bottom of the positioning plate 11. A moving component is provided at the bottom of the U-shaped frame 7.

[0033] Reference Figures 3-5The outer wall of the slide rod 9 is slidably connected to the inner wall of the U-shaped frame 7. The top end of the telescopic spring 10 is fixedly connected to the inner surface of the U-shaped frame 7. The guide assembly includes a mounting groove 12, which is opened on the lower surface of the positioning plate 11. Two sets of guide assemblies are provided, and the two sets of guide assemblies are symmetrically arranged about the central axis of the positioning plate 11. The inner wall of the positioning plate 11 is provided with a sliding groove 13, which is located inside the mounting groove 12. Each set of mounting grooves 12 has two sets of sliding grooves 13 inside. Each pair of opposite sliding grooves 13 is slidably connected to two sets of sliders 14. The inner wall of the sliding groove 13 is slidably connected to a slider 14, and the top end of the slider 14 is fixedly connected to a connecting rod 15. The side wall is rotatably connected to a guide wheel 23, and an inclined block 17 is fixedly connected to the surface of the guide wheel 23. When the guide wheel 23 rotates counterclockwise, the higher end of the inclined block 17 is closer to the polishing component 2. The inclined block 17 is made of rubber, which increases the friction when the positioning plate 11 contacts the square tube. The top of the connecting rod 15 is fixedly connected to a limit spring 16, and the top of the limit spring 16 is fixedly connected to the inner wall of the mounting groove 12. The moving component includes a guide rail 4, the bottom of the guide rail 4 is fixedly connected to the upper surface of the worktable 1, the bottom of the guide rail 4 is fixedly connected to a support frame 5, and the outer wall of the guide rail 4 is slidably connected to a sliding plate 6. The upper surface of the sliding plate 6 is fixedly connected to the lower surface of the U-shaped frame 7.

[0034] Reference Figures 2-3 A water tank 20 is fixedly connected to the outer wall of the workbench 1. The interior of the water tank 20 is used to hold clean water. A connecting hose 19 is fixedly connected to the inner wall of the water tank 20. A corrugated pipe 18 is fixedly connected to the outer wall of the connecting hose 19. The corrugated pipe 18 has a telescopic deformation function. When the corrugated pipe 18 is stretched, water from inside the water tank 20 is introduced through the connecting hose 19. One end of the corrugated pipe 18 is fixedly connected to the outer wall of the workbench 1, and the other end of the corrugated pipe 18 is fixedly connected to the side wall of the sliding plate 6. A strong magnet 21 is fixedly connected to the side wall of the sliding plate 6, and a strong magnet 22 is fixedly connected to the outer wall of the support frame 5. The magnetism of the strong magnet 21 and the strong magnet 22 on opposite sides is mutually repulsive.

[0035] Working principle: The square tube is placed by the fixing seat of the fixing component 3. The screw on the fixing seat drives the clamping plate to fix the square tube. The fixing seat moves towards the polishing component 2 in the moving groove on the worktable 1. The polishing component 2 polishes all four sides of the square tube at the same time. When the area where the square tube is fixed needs to be polished, the fixing component 3 is removed from the square tube, and the square tube is pushed towards the polishing component 2. The opening of the square tube will enter the interior of the U-shaped frame 7 and contact the guide wheel 23. The guide wheel 23 drives the connecting rod 15 to compress the limiting spring 16 and cause it to retract, so that the slider 14 slides inside the slide groove 13 until it can no longer move. The positioning plate 11 is displaced upward by force, the telescopic spring 10 is compressed and the slide rod 9 moves upward, so that the positioning plate 11 fixes the top of the square tube. At this time, the guide wheel 23 is inside the mounting groove 12, but the tilting block 17 is located inside the mounting groove 12. The groove of the mounting slot 12 contacts the square tube. When the opening of the square tube moves continuously to the left, the inclined surface of the inclined block 17 will not obstruct the movement of the square tube. When the square tube moves in the opposite direction, the friction between the protruding end of the inclined surface and the square tube increases, thereby ensuring that the opening area of ​​the square tube is stably fixed in the U-shaped frame 7. The operator manually pulls the U-shaped frame 7 to move away from the polishing component 2. At this time, the corrugated pipe 18 is stretched and the water source introduced into the water tank 20 enters the interior to provide a buffer for the displacement of the U-shaped frame 7. The sliding plate 6 slides on the two sets of guide rails 4 to ensure the stability of the square tube displacement. At the same time, due to the repulsive force between the strong magnet 1 21 and the strong magnet 22, the force applied by the U-shaped frame 7 is prevented from being too large and causing the end of the square tube to detach from the polishing component 2, thereby ensuring that the end of the square tube receives the same degree of polishing effect on the tube body and ensuring the consistency of polishing.

[0036] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
