[0016] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. The described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.
[0017] See also Figure 1-3The utility model provides a technical solution: an aluminum alloy polishing device, including a workbench 1, a mounting frame 5 is slidably mounted on the workbench 1, a polishing mechanism 9 is arranged in the mounting frame 5, the polishing mechanism 9 includes an electric hydraulic push rod 10 and a mounting plate 11, the electric hydraulic push rod 10 is mounted in the mounting frame 5, a mounting plate 11 is arranged at the output end of the electric hydraulic push rod 10, a U-shaped frame 12 is arranged at the center of the lower surface of the mounting plate 11, a polishing disc 13 is rotatably mounted on the inner side of the U-shaped frame 12, a driving motor 14 for driving the polishing disc 13 is arranged on one side of the U-shaped frame 12, sliding rods 15 are arranged on both sides of the lower surface of the mounting plate 11, a sliding sleeve 17 is slidably sleeved at the end of the sliding rod 15, a telescopic spring 16 is sleeved on the sliding rod 15, one end of the telescopic spring 16 is fixedly connected to the mounting plate 11, and the other end of the telescopic spring 16 is fixedly connected to the sliding sleeve 17, and a pressing roller 18 is rotatably mounted on the inner side of the sliding sleeve 17;
[0018] When in use, the aluminum alloy tube to be polished is placed on the workbench 1, and the joint of the aluminum alloy tube is upwardly aligned with the position of the polishing disc 13, and then the mounting plate 11 is pushed downward by the electric hydraulic push rod 10, and at the same time, the polishing disc 13 and the pressing roller 18 are driven downward, and then the pressing roller 18 first contacts the surface of the aluminum alloy tube, and then the polishing disc 13 and the pressing roller 18 are continuously pushed downward, and the pressing roller 18 drives the sliding sleeve 17 to produce relative movement along the sliding rod 15, and at the same time, the telescopic spring 16 is squeezed, and the downward impact of the polishing disc 13 is consumed through the deformation of the telescopic spring 16 to avoid collision between the polishing disc 13 and the surface of the aluminum alloy tube, and then the polishing disc 13 contacts the surface of the aluminum alloy tube, and then the surface of the aluminum alloy tube is polished by the polishing disc 13.
[0019] Among them, frames 2 are provided at both ends of the workbench 1, and two symmetrically arranged threaded screws 3 are rotatably installed between the two frames 2. A servo motor 4 is provided at the position corresponding to the threaded screw 3 on one of the frames 2, and the output end of the servo motor 4 is fixedly connected to the end of the threaded screw 3. A nut sleeve 6 is threadedly installed on the threaded screw 3, and the bottom of the mounting frame 5 is fixedly connected to the nut sleeve 6. When the polishing disc 13 starts to polish the joint of the aluminum alloy pipe, the servo motor 4 is turned on, and the threaded screw 3 is driven to rotate by the servo motor 4. During the rotation of the threaded screw 3, the nut sleeve 6 moves along the threaded screw 3, thereby driving the mounting frame 5 to move along the threaded screw 3, so that the polishing disc 13 can be moved along the joint of the aluminum alloy pipe, so that the polishing disc 13 is convenient for continuous polishing along the joint seam of the aluminum alloy pipe, thereby improving work efficiency.
[0020] Among them, a guide rod 8 is provided at a position corresponding to the threaded screw 3 on the surface of the workbench 1, a guide roller 7 is provided at the bottom of the nut sleeve 6, and an annular groove cooperating with the guide rod 8 is opened on the surface of the guide roller 7. When the nut sleeve 6 moves along the threaded screw 3, the guide roller 7 rolls along the guide rod 8 through the annular groove, thereby limiting the position of the nut sleeve 6, preventing the nut sleeve 6 from rotating synchronously with the threaded screw 3, and ensuring that the nut sleeve 6 can be driven to move during the rotation of the threaded screw 3.
[0021] Among them, the guide rod 8 is arranged parallel to the threaded screw 3, and an arc groove is opened on the surface of the workbench 1. The arc groove and the threaded screw 3 are arranged parallel to each other. The movement trajectory of the polishing disk 13 is located directly above the arc groove. When the splicing seam of the aluminum alloy tube needs to be polished, the aluminum alloy tube is placed on the surface of the workbench 1, and the aluminum alloy tube is placed in the arc groove. The aluminum alloy tube is limited by the arc groove to prevent the aluminum alloy tube from rolling on the surface of the workbench 1, and then the splicing seam of the aluminum alloy tube is aligned with the movement trajectory of the polishing disk 13. In this way, when the polishing disk 13 is driven to move with the nut sleeve 6, it can be ensured that the polishing disk 13 is polished on the splicing seam of the aluminum alloy tube.
[0022] Working principle: When in use, place the aluminum alloy tube on the surface of the workbench 1 and in the arc groove. The aluminum alloy tube is limited by the arc groove to prevent the aluminum alloy tube from rolling on the surface of the workbench 1. Then align the joint of the aluminum alloy tube with the movement trajectory of the polishing disc 13. Then, push the mounting plate 11 downward through the electric hydraulic push rod 10, and drive the polishing disc 13 and the pressing roller 18 to move downward at the same time. Then, the pressing roller 18 first contacts the surface of the aluminum alloy tube, and then continuously pushes the polishing disc 13 and the pressing roller 18 to move downward. The pressing roller 18 drives the sliding sleeve 17 to move relative to the sliding rod 15, and at the same time, the telescopic spring 16 is produced. The downward impact of the polishing disc 13 is consumed by the deformation of the telescopic spring 16 to avoid the collision between the polishing disc 13 and the surface of the aluminum alloy tube. The polishing disc 13 contacts the surface of the aluminum alloy tube, and then the surface of the aluminum alloy tube is polished by the polishing disc 13. At the same time, the servo motor 4 is turned on, and the threaded screw 3 is driven to rotate by the servo motor 4. During the rotation of the threaded screw 3, the nut sleeve 6 moves along the threaded screw 3, thereby driving the mounting frame 5 to move along the threaded screw 3, so that the polishing disc 13 can be moved along the joint of the aluminum alloy tube, so that the polishing disc 13 can be continuously polished along the joint of the aluminum alloy tube, thereby improving work efficiency.
