[0021] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative. This utility model is not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
[0022] Reference Figures 1-5 This utility model provides a shaft grinding debris cleaning device, including a receiving box 1, with a discharge port 2 at the top of the receiving box 1. Side plates 3 are bolted to the top outer wall of the receiving box 1 on both sides of the discharge port 2. Two symmetrical guide rods 4 are bolted between the two side plates 3. A fixing plate 10 and a T-shaped guide rail 11 are bolted to the top outer wall of the receiving box 1 on the other two sides of the discharge port 2. A sliding plate 12 is slidably connected to the T-shaped guide rail 11. The sliding plate 12 and the fixing plate 10... Rotating clamps 14 are rotatably connected to opposite sides of plate 10. A drive motor 13 is bolted to one side of the slide plate 12 to rotate the rotating clamp 14 on that side. Support plates 5 are bolted to the middle of the two guide rods 4. Connecting plates 6 are bolted to the top of the two support plates 5. Two sliding rods 7 are slidably connected through the connecting plate 6. A horizontal plate 8 is bolted to the top of the two sliding rods 7. Cleaning cotton 9 is glued to the horizontal plate 8. The upper surface of the cleaning cotton 9 is in contact with the shaft surface.
[0023] Specifically, when grinding the shaft to be processed, the shaft is first installed between two rotating chucks 14, and then the bidirectional lead screw 18 is rotated. While the bidirectional lead screw 18 is rotating, it will drive the two moving frames 17 to move closer to each other. While the two moving frames 17 are moving closer to each other, multiple T-shaped frames 19 will drive multiple positioning clamping wheels 20 to clamp and fix the shaft.
[0024] The horizontal plate 8 and the cleaning cotton 9 that is in close contact with the shaft can clean the residual debris adhering to the shaft surface during the grinding process, ensuring the accuracy of the shaft grinding. The movable frame 17 and multiple positioning clamping wheels 20 can ensure that the axis of the shaft being processed always remains in a straight line during the processing, further ensuring the processing accuracy.
[0025] In this utility model, two symmetrical movable frames 17 are slidably connected to the two guide rods 4. The upper surfaces of the two movable frames 17 are fixedly connected to T-shaped frames 19 by bolts. The opposite sides of the multiple T-shaped frames 19 are rotatably connected to two upper and lower positioning clamping wheels 20. The multiple sets of positioning clamping wheels 20 are in close contact with the processing shaft. The two side plate 3 supports are rotatably connected to a bidirectional lead screw 18 through bearings. The bidirectional lead screw 18 passes through the two movable frames 17 and is threadedly connected to them. One end of the bidirectional lead screw 18 passes through one side of one of the side plates 3.
[0026] Specifically, the electric push rod 21 is then activated to retract, thereby pushing the slide plate 12 to press against the T-shaped guide rail 11 and move through the connecting rod 23 and the round rod 22. As the slide plate 12 moves, it drives the rotating chuck 14 on it to fix the two ends of the machining shaft.
[0027] In this utility model, a round rod 22 is fixedly connected to one side of the slide plate 12 by bolts, and a connecting rod 23 is fixedly connected to one end of the round rod 22 by bolts. An electric push rod 21 is fixedly connected to one side of the outer wall of the receiving box 1 by bolts. The output end of the electric push rod 21 is fixed to one side of the connecting rod 23. An inclined plate 24 is fixedly connected to the upper surface of the two side plates 3 by bolts. The two inclined plates 24 are inclined to both sides and the length of the inclined plate 24 is the same as that of the side plate 3. A limiting port 15 is opened on one side of the receiving box 1. A material drawer 16 is slidably connected inside the limiting port 15. The upper surface of the cleaning cotton 9 is concave downwards, and the shape of the concave downwards is the same as the shape of the processing shaft.
[0028] Specifically, after the shaft is fixed, the drive motor 13 is started to rotate the shaft by rotating the chuck 14. Then, the surface of the shaft is polished manually. During the polishing process, the debris adhering to the shaft surface is cleaned off by the cleaning cotton 9. The fallen debris falls into the material drawer 16 in the receiving box 1. After processing is completed, it can be pulled out and cleaned.
[0029] The inclined plate 24 increases the range of debris collection, effectively reducing the amount of grinding debris splashing outside the device.
[0030] It should be noted that the inner wall of the threaded hole on the movable frame 17 is provided with an annular groove in the axial direction. A nylon 66 damping ring with a Shore hardness of 85A is embedded in the groove. The continuous axial clamping force generated by its elastic deformation forms a helical angle interference fit with the surface of the double-acting screw 18 at 15°-20°. When the threaded pair is subjected to axial vibration load, the nylon insert can generate a maximum elastic compression of 0.3mm, which increases the friction coefficient between the thread contact surfaces from 0.15 to 0.68 (tested according to ASTM D1894 standard), effectively suppressing the loosening displacement caused by thread springback.
[0031] It should be noted that the drive motor 13 and the electric push rod 21 are both existing technologies, and those skilled in the art can set them according to actual needs, which will not be elaborated here.
[0032] The use of this utility model involves the following steps:
[0033] S1: When grinding the shaft to be processed, first install the shaft between two rotating chucks 14, then rotate the double-acting screw 18. While the double-acting screw 18 is rotating, it will drive the two moving frames 17 to move closer to each other. While the two moving frames 17 are moving closer to each other, multiple T-shaped frames 19 will drive multiple positioning clamping wheels 20 to clamp and fix the shaft.
[0034] S2: Then the electric push rod 21 is activated to retract, thereby pushing the slide plate 12 to press against the T-shaped guide rail 11 and move through the connecting rod 23 and the round rod 22. While the slide plate 12 is moving, it will drive the rotating chuck 14 on it to fix the two ends of the processing shaft.
[0035] S3: After the shaft is fixed, start the drive motor 13 to rotate the shaft by rotating the chuck 14. Then, manually polish the surface of the shaft. During the polishing process, the debris adhering to the shaft surface is cleaned off by the cleaning cotton 9. The fallen debris falls into the material drawer 16 in the receiving box 1. After processing is completed, it can be pulled out and cleaned.
[0036] Finally, the following points should be noted: In the description of this application, it should be noted that, unless otherwise specified and limited, the terms "installation", "connection" and "linkage" should be interpreted broadly, and can be mechanical or electrical connection, or internal connection between two components, or direct connection. "Up", "down", "left", "right", etc. are only used to indicate relative positional relationship.

[0037] The electronic components and modules used in this utility model can all be parts that are commonly used in the market and can achieve the specific functions in this case. The specific models and sizes can be selected and adjusted according to actual needs.
