[0002] A CNC polishing machine is a type of polishing machine used in workshops to polish and grind the surface of items, enabling the surface of the items to achieve a certain degree of smoothness.

[0003] In the existing technology, when polishing the surface of steel pipes, the steel pipes need to be placed on the bearing rollers, and then the polishing mechanism moves to perform the polishing operation. After the polishing operation is completed, the steel pipes need to be picked up manually. Therefore, the automation is poor, the manual labor intensity is high, and the work efficiency is affected, so there is room for improvement. Utility Model Content

A first roller and a second roller are rotatably mounted at both ends of the first U-shaped frame, and a third roller is rotatably mounted between the first and second rollers. The outer ends of the first and second rollers rotatably pass through the first U-shaped frame, and a first gear disc is mounted at the end of the first roller, a second gear disc is mounted at the end of the second roller, and a third gear disc is mounted in the middle of the third roller. A second U-shaped frame is slidably mounted on the front side of the mounting groove within the frame. The second U-shaped frame has a first auxiliary roller, a second auxiliary roller, and a third auxiliary roller rotatably mounted inside, corresponding to the first roller shaft, the second roller shaft, and the third roller shaft. Several storage racks are fixed at equal intervals on the front side of the second U-shaped frame. A first hydraulic telescopic rod is provided in the mounting groove between the first roller shaft and the third roller shaft, and between the second roller shaft and the third roller shaft. A push plate is installed at the telescopic ends of the two first hydraulic telescopic rods. A gantry frame is installed in the frame. Two telescopic cylinders are installed in the gantry frame. The telescopic end of the second telescopic cylinder is connected to a mounting plate. Several positioning wheels are rotatably mounted at equal intervals on the bottom surface of the mounting plate. A guide rod that is slidably connected to the gantry frame is fixed at the upper part of both ends of the mounting plate.

[0006] Preferably, a drive shaft is rotatably mounted at the bottom of the frame on the rear side of the mounting slot, and one end of the drive shaft is connected to a drive motor. The two ends and the middle part of the drive shaft are respectively equipped with a first drive gear plate, a second drive gear plate, and a third drive gear plate that match the first gear plate, the second gear plate, and the third gear plate.

[0007] Preferably, the front side of the frame has three equally spaced sliding grooves, and the bottom end of the second U-shaped frame is respectively equipped with sliders that are slidably connected to the three sliding grooves.

[0010] The beneficial effects of adopting the above technical solutions are: The steel pipe is fed into the space between the first, second, and third rollers and the first, second, and third auxiliary rollers via an external feeding device. Then, the mounting plate is driven to move downwards via a second hydraulic telescopic rod, and the positioning wheel positions the steel pipe against the surface. The polishing mechanism then moves to perform the polishing operation. After polishing, the push plate is driven to move upwards via the first hydraulic telescopic rod, causing the movable plate to contact the lower surface of the steel pipe and lift it up. The movable plate is then tilted at an angle via the third hydraulic telescopic rod, allowing the steel pipe to be guided into the storage rack, completing the automatic unloading operation and improving work efficiency.

[0020] like Figure 1-5In this embodiment, a CNC polishing machine includes a frame 1 and a polishing mechanism 2. The polishing mechanism 2 is slidably mounted on the rear side of the frame 1. A mounting groove 11 is provided in the middle of the frame 1, and a first U-shaped frame 3 is mounted on the rear side of the mounting groove 11 in the frame 1. A first roller 31 and a second roller 32 are rotatably mounted at both ends of the first U-shaped frame 3, and a third roller 33 is rotatably mounted between the first roller 31 and the second roller 32. The outer ends of the first roller 31 and the second roller 31 rotatably pass through the first U-shaped frame 3, and a first gear disk 311 is mounted at the end of the first roller 31, a second gear disk 321 is mounted at the end of the second roller 32, and a third gear disk 331 is mounted in the middle of the third roller 33. A second U-shaped frame 4 is slidably mounted on the front side of the mounting groove 11 in the frame 1. The frame 4 is rotatably mounted with a first auxiliary roller 41, a second auxiliary roller 42, and a third auxiliary roller 43 corresponding to the first roller shaft 31, the second roller shaft 32, and the third roller shaft 33. Several storage racks 5 are fixed at equal intervals on the front side of the second U-shaped frame 4. A first hydraulic telescopic rod 6 is provided in the mounting groove 11 between the first roller shaft 31 and the third roller shaft 33, and between the second roller shaft 32 and the third roller shaft 33. A push plate 61 is installed at the telescopic ends of the two first hydraulic telescopic rods 6. A gantry frame 7 is installed in the frame 1. Two telescopic cylinders 71 are installed in the gantry frame 7. The telescopic ends of the second telescopic cylinders 71 are connected to a mounting plate 72. Several positioning wheels 73 are rotatably mounted at equal intervals on the bottom surface of the mounting plate 72. A guide rod 74 that is slidably connected to the gantry frame 7 is fixed at the upper part of both ends of the mounting plate 72.

[0021] Through the above technical solution, the steel pipe is fed into the space between the first roller 31, the second roller 32, the third roller 33 and the first auxiliary roller 41, the second auxiliary roller 42, and the third auxiliary roller 43 via an external feeding device. Then, the mounting plate 72 is driven to move downwards by the second hydraulic telescopic rod 71, and the positioning wheel 73 is used to position the steel pipe surface. Then, the polishing mechanism 2 moves in the frame to perform polishing. After polishing, the push plate 61 is driven to move upwards by the first hydraulic telescopic rod 6, lifting the steel pipe so that it is separated from the first roller 31, the second roller 32, the third roller 33 and the first auxiliary roller 41, the second auxiliary roller 42, and the third auxiliary roller 43. Then, the steel pipe tilts and rolls into the storage rack 5, completing the automatic unloading operation and improving work efficiency.

[0022] Preferably, a drive shaft 8 is rotatably mounted at the bottom of the frame 1, located behind the mounting groove 11, and one end of the drive shaft 8 is connected to a drive motor 9. The two ends and the middle part of the drive shaft 8 are respectively equipped with a first drive gear 81, a second drive gear 82, and a third drive gear 83 that match the first gear disk 311, the second gear disk 321, and the third gear disk 331. The first gear disk 311 is connected to the first drive gear 81, the second gear disk 321 is connected to the second drive gear 82, and the third gear disk 331 is connected to the third drive gear 83 by a chain.

[0023] Through the above technical solution, the drive motor 9 drives the transmission shaft 8 to rotate, thereby driving the first gear disk 311, the second gear disk 321, and the third gear disk 331 to rotate synchronously through the first drive gear disk 81, the second drive gear disk 82, and the third drive gear disk 83 in conjunction with the chain. This causes the first roller shaft 31, the second roller shaft 32, and the third roller shaft 33 to rotate synchronously, thereby driving the placed steel pipe to rotate, improving polishing efficiency and stability.

[0024] Preferably, the front side of the frame 1 is provided with three sliding grooves 12 at equal intervals, and the bottom end of the second U-shaped frame 4 is respectively equipped with sliders 44 that are slidably connected to the three sliding grooves 12. The front middle part of the frame 1 is provided with an adjusting screw 13, which rotates through the middle sliding groove 12 and is threadedly connected to the slider 44 at the middle of the bottom surface of the second U-shaped frame 4.

[0025] Through the above technical solution, the setting of the adjusting screw 13 is used to drive the second U-shaped frame 4 to slide on the front side of the frame 1, thereby adjusting the position between it and the first U-shaped frame 3, which facilitates the placement of steel pipes of different sizes and improves applicability.

[0026] Preferably, the push plate 61 has two I-shaped movable plates 62 symmetrically hinged, and the movable plates 62 are located at the top of the first hydraulic telescopic rod 6. A positioning plate 63 is fixedly provided on the rear side of the push plate 61, and a third hydraulic telescopic rod 64 is installed in the positioning plate 63. The top end of the third hydraulic telescopic rod 64 is hinged to the bottom surface of the movable plate 62.

[0027] Through the above technical solution, the third hydraulic telescopic rod 64 drives the movable plate 61 to move on the push plate 61, so that the movable plate 61 is tilted at a small angle, thereby allowing the lifted steel pipe to move along the inclined surface into the storage rack 5, thus completing the automatic unloading process, improving work efficiency, and reducing labor intensity by eliminating the need for manual unloading.

[0028] Preferably, a plurality of silicone sheets 51 are installed at equal intervals on the upper surface of the storage rack 5.

[0029] Through the above technical solution, the setting of the silicone sheet 51 reduces the rolling speed of the steel pipe in the storage rack 5, reduces the impact force generated when the steel pipe is unloaded, and ensures the quality of the product.

[0030] Finally, it should be noted that the above embodiments are only used to illustrate this utility model and are not intended to limit the technical solutions described in this utility model. Therefore, although this specification has described this utility model in detail with reference to the above embodiments, those skilled in the art should understand that modifications or equivalent substitutions can still be made to this utility model, and all technical solutions and improvements that do not depart from the spirit and scope of this utility model should be covered within the scope of the claims of this utility model; technologies not described in detail in this utility model are implemented using existing technologies.
