[0017] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0018] See also Figure 1 and Figure 3 As shown, the utility model provides the following technical solutions: a device for processing an arc-shaped headlamp lampshade includes a motor 1, a grinding sandpaper 3, a main body 7 and a connecting assembly, the motor 1 is arranged on the top of the main body 7, and the connecting assembly is fixed to the end of the motor 1, the grinding sandpaper 3 is wrapped around the outer wall of the connecting assembly, and the connecting assembly is used to change the end surface shape of the grinding sandpaper 3. The connecting assembly includes a connecting disk 2, an elastic rubber 12 and an elastic ring 14, the end of the motor 1 is provided with a connecting disk 2, the elastic rubber 12 is cylindrical, and the elastic rubber 12 is arranged It is placed at the bottom of the connecting disk 2, and the grinding sandpaper 3 is wrapped around the outer wall of the elastic rubber 12, and an elastic ring 14 is sleeved on the outer periphery of the side wall of the grinding sandpaper 3, the inner wall of the elastic ring 14 is in contact with the side wall of the grinding sandpaper 3, the diameter of the elastic rubber 12 is smaller than the diameter of the connecting disk 2, and a positioning groove 13 is provided on the outer wall of the end of the elastic rubber 12 that contacts the connecting disk 2, and the positioning groove 13 is annular, the elastic ring 14 and the end of the grinding sandpaper 3 are both embedded in the positioning groove 13, and the inner diameter of the elastic ring 14 is smaller than the diameter of the elastic rubber 12.

[0019] Through the above technical scheme: when in use, the motor 1 drives the grinding sandpaper 3 to move downward until the grinding sandpaper 3 contacts the surface of the lampshade. With the continuous pushing of the motor 1, the grinding sandpaper 3 is forced to squeeze the elastic rubber 12 due to the obstruction of the lampshade, causing the elastic rubber 12 and the end surface of the grinding sandpaper 3 to begin to deform synchronously, so that the grinding sandpaper 3 is in close contact with the surface of the lampshade. With the driving rotation of the motor 1, automatic grinding can be completed. At the same time, there is no need to use a mechanical arm, which solves the current problems of low processing efficiency and high investment cost in the process of grinding the lampshade. After long-term use, since the grinding sandpaper 3 is fixed to the elastic rubber 12 through the elastic ring 14, when replacing the grinding sandpaper 3, it is only necessary to pull out the elastic ring 14 downward to disengage it from the positioning groove 13 to complete the disassembly. The opening of the positioning groove 13 reduces the situation where the elastic ring 14 slides downward autonomously due to vibration during operation.

[0020] See also Figure 1-Figure 3As shown, a placement groove 8 is provided at the bottom of the inner wall of the main body 7 and directly below the elastic rubber 12, a limit plate 10 is provided in the placement groove 8, a through hole is provided in the middle of the limit plate 10, the through hole is on the same axis as the rotating shaft of the motor 1, and a headlamp cover is embedded in the through hole, movable grooves 6 are symmetrically provided on both sides of the limit plate 10, a connecting rod 5 is provided in the movable groove 6, and the diameter of the connecting rod 5 is smaller than the thickness of the limit plate 10, filter plates 11 are symmetrically installed on both sides of the inner wall of the main body 7, and grooves are symmetrically provided on both sides of the outer wall of the main body 7, air holes are symmetrically provided on the inner wall of the groove and on one side close to the filter plate 11 at equal intervals, and an air pipe 9 is also provided in the groove, and air nozzles 4 are symmetrically installed on the surface of the air pipe 9 and on one side relative to the filter plate 11 at equal intervals, and the air nozzles 4 extend into the air holes.

[0021] Through the above technical scheme: before use, the limit plate 10 is embedded into the movable groove 6 on the inner wall of the main body 7 through the connecting rod 5. At this time, the lampshade is buckled in the through hole on the limit plate 10, and the positioning of the lampshade is completed by utilizing the through hole and the interlocking connection between the limit plate 10 and the movable groove 6 to ensure the polishing effect during subsequent processing. At the same time, the air pipes 9 on both sides are connected to the air pump. When in use, the air pump, air pipe 9 and air nozzle 4 are used to evacuate air, driving the dust generated during polishing to move synchronously with the nearby air to the filter plates 11 on both sides, and the filter plates 11 are used to absorb and entrain the dust, thereby reducing the impact of dust on the surrounding environment and production personnel. At the same time, since the filter plate 11 is fixed on the inner wall of the main body 7, the operator can directly contact it, thereby simplifying the subsequent steps of disassembling and cleaning the filter plate 11, and improving the dust removal effect of the equipment itself.
