Description

Technical Field

[0001] This utility model relates to the field of polishing protection technology, and more specifically, to a splash guard for crankshaft polishing. Background Technology

[0002] The crankshaft is a key component of an engine, enduring enormous pressure and friction during operation. To reduce friction during subsequent operation and improve engine efficiency and lifespan, grinding and polishing the crankshaft is essential.

[0003] Crankshaft polishing generates a large amount of debris. This debris is prone to flying and is not only difficult to clean, but also poses a threat to the working environment and personnel safety. Specific problems include: Cleaning difficulties: The flying debris will scatter in every corner of the work area, increasing the difficulty and workload of cleaning.

[0004] Safety hazard: Flying debris can easily get into workers' eyes, potentially causing eye injuries and other safety accidents.

[0005] Limited protective effect: Existing polishing machine guards are not effective in preventing debris from flying and cannot effectively solve the problem of flying debris.

[0006] Inconvenient loading and unloading: Some protective covers block the polished parts of the crankshaft, making it difficult to load and unload the crankshaft, which affects work efficiency.

[0007] In summary, existing crankshaft polishing technologies and protective measures cannot effectively solve the problem of debris splashing, resulting in shortcomings such as cleaning difficulties, safety hazards, limited protective effect, and inconvenience in loading and unloading. Therefore, a special anti-splash protective cover for crankshaft polishing is needed to overcome the deficiencies of existing technologies and improve the safety and efficiency of the crankshaft polishing process.

[0027] Please see Figure 1-5 A splash guard for crankshaft polishing includes a worktable 1. Three sides of the worktable 1 are fixed with baffles 2, and the three baffles 2 together with the worktable 1 form a polishing space. A first protective plate 3 is hinged to one side of the worktable 1 to seal the front of the polishing space and prevent debris from splashing. A second protective plate 4 is movably installed on the top of the three baffles 2 to seal the top of the polishing space and prevent debris from splashing. A through groove 401 is provided on the second protective plate 4, and a suction hood 5 is installed at the through groove 401. An exhaust pipe 6 connected to the polishing space is installed on the suction hood 5, and the exhaust pipe 6 is connected to an external suction device to extract debris generated within the polishing space.

[0028] In practical applications, the polishing equipment for crankshaft polishing and the clamping equipment for crankshaft clamping are installed on the worktable 1 and located within the polishing space. When polishing is required, the first protective plate 3 and the second protective plate 4 are rotated to close, thus shielding the polishing space and preventing debris generated during polishing from splashing into the external environment. During this process, the external suction equipment is activated to extract the debris in the polishing space through the suction pipe 6 and the suction hood 5. When polishing is not required, the first protective plate 3 and the second protective plate 4 are rotated to open, allowing for loading and unloading of materials.

[0029] In this embodiment, two symmetrically installed baffle plates 2 are each fixed with a first fixing plate 7 and a second fixing plate 8. The first protective plate 3 has a first rotating shaft 9 on both sides. The two first fixing plates 7 have first through holes 701 through which the first rotating shaft 9 passes, and the first rotating shaft 9 is rotatably placed within the first through holes 701. The second protective plate 4 has a second rotating shaft 10 on both sides. The two second fixing plates 8 have second through holes 801 through which the second rotating shaft 10 passes, and the second rotating shaft 10 is rotatably placed within the second through holes 801. A linkage mechanism is provided between the first rotating shaft 9 and the second rotating shaft 10 to enable their joint rotation. The linkage mechanism includes a third rotating shaft 11 and a fourth rotating shaft 12 that are linked together. The third rotating shaft 11 and the fourth rotating shaft 12 are rotatably mounted on one of the baffle plates 2. A first gear 13 and a second gear 14, which mesh with each other, are respectively fixedly sleeved on the outside of the third rotating shaft 11 and the fourth rotating shaft 12. The transmission ratio of the first gear 13 to the second gear 14 is 2:1. The third rotating shaft 11 and the first rotating shaft 10 are linked together. A first transmission group 15 is provided between shafts 9 to enable them to work together, and a second transmission group 16 is provided between the fourth rotating shaft 12 and the second rotating shaft 10 to enable them to work together. The first transmission group 15 and the second transmission group 16 have the same structure, both including a first pulley 17, a second pulley 18, and a transmission belt 19 for connecting the first pulley 17 and the second pulley 18. The first pulley 17 and the second pulley 18 in the first transmission group 15 are respectively fixedly sleeved on the outside of the third rotating shaft 11 and the first rotating shaft 9. The second transmission group 16... The first pulley 17 and the second pulley 18 in 6 are respectively fixedly sleeved on the fourth rotating shaft 12 and the second rotating shaft 10. A protective cover 20 for blocking the linkage mechanism is installed on the baffle plate 2. The protective cover 20 has a clearance groove 2001 for the first transmission group 15 and the second transmission group 16 to pass through. The anti-splash protective cover for crankshaft polishing also includes a drive motor 21 for driving the third rotating shaft 11. The drive motor 21 is installed on the outside of the protective cover 20, and its drive shaft passes through the protective cover 20 and is connected to the third rotating shaft 11.

[0030] In specific applications, when driving the first protective plate 3 and the second protective plate 4 to rotate, the drive motor 21 is started, which drives the third rotating shaft 11 to rotate. The third rotating shaft 11 rotates through the meshing of the first gear 13 and the second gear 14. When the third rotating shaft 11 rotates, it can also drive the first rotating shaft 9 to rotate through the first transmission group 15. When the fourth rotating shaft 12 rotates, it can drive the second rotating shaft 10 to rotate through the second transmission group 16, so as to realize the synchronous rotation of the first protective plate 3 and the second protective plate 4. When the first protective plate 3 rotates 180 degrees to fully open, the second protective plate 4 rotates 90 degrees to the vertical position.

[0031] Of all the solutions mentioned above, those involving the connection between two components can be selected according to the actual situation, such as welding, bolt and nut connection, bolt or screw connection, or other known connection methods, which will not be elaborated here. For all the fixed connections mentioned above, welding is preferred. Although embodiments of this utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of this utility model.
