DETAILED DESCRIPTION

[0018] The technical solutions in the embodiments of the present invention are described clearly and completely below. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0019] Embodiment 1: A hole trimming device for lampshade production, such as Figure 1-Figure 4As shown, it includes a base 1, on which a lampshade 21 is placed, on which a support rod 2 is welded, on which an electric hydraulic cylinder 3 is fixedly connected to the top of the support rod 2, on which a grinding component is provided, and the electric hydraulic cylinder 3 is used to drive the grinding component to rise and fall.

[0020] The grinding component includes a mounting frame 4, which is fixedly connected to the bottom end of the telescopic rod of the electric hydraulic cylinder 3, and the mounting frame 4 is slidably connected to the support rod 2. A pressing ring 5 is fixedly connected to the bottom of the mounting frame 4, and a plurality of rubber heads 51 are provided on the pressing ring 5. The rubber heads 51 are used to limit the lampshade 21. A motor 6 is fixedly connected inside the mounting frame 4, and a grinding head 7 is fixedly connected to the output shaft of the motor 6. The grinding head 7 is used to grind the holes of the lampshade 21, and the grinding head 7 passes through the pressing ring 5.

[0021] At first, the staff places the lampshade 21 that needs round hole trimming in the middle of the base 1, and then the staff starts the electric hydraulic cylinder 3. The telescopic rod of the electric hydraulic cylinder 3 descends, which will drive the mounting frame 4, the pressing ring 5, the motor 6 and the grinding head 7 to descend together. The grinding head 7 descends and contacts with the holes of the lampshade 21 around. Then the pressing ring 5 descends and contacts with the lampshade 21 and limits the lampshade 21. The staff turns off the electric hydraulic cylinder 3, and then the staff starts the motor 6. The output shaft of the motor 6 rotates to drive the grinding head 7 to rotate. The grinding head 7 rotates to achieve the trimming of the holes in the lampshade 21. After grinding, the staff turns off the motor 6, and the staff starts the telescopic rod of the electric hydraulic cylinder 3 to rise. The rising telescopic rod of the electric hydraulic cylinder 3 will drive the mounting frame 4, the pressing ring 5, the motor 6 and the grinding head 7 to reset upwards. Then the staff removes the trimmed lampshade 21 and replaces it with a new untrimmed lampshade 21. This reciprocating process is used to trim the holes in the lampshade 21.

[0022] Embodiment 2: Based on embodiment 1, Figure 5-Figure 6 As shown, it also includes a sliding mounting block 71, and the two sliding mounting blocks 71 are fixedly connected to the base 1. The two sliding mounting blocks 71 are symmetrically arranged, and the two sliding mounting blocks 71 are slidably connected with a clamping rod 8, and the clamping rod 8 is used to clamp the lampshade 21. A pressure spring 9 is connected between the clamping rod 8 and the sliding mounting block 71, and the pressure spring 9 is used to drive the clamping rod 8 to reset. An extrusion rod 10 is fixedly connected to the installation frame 4, and the extrusion rod 10 is located above the two clamping rods 8.

[0023] It also includes a positioning plate 13 , which is fixed on the base 1 .

[0024] It also includes two rotating mounting plates 101, both of which are fixedly connected to the base 1, a swing rod 11 is rotatably connected between the two rotating mounting plates 101, the swing rod 11 is used to tilt the lampshade 21, the swing rod 11 is stuck in the base 1, and a torsion spring 12 is connected between the swing rod 11 and the two rotating mounting plates 101.

[0025] When the mounting frame 4 descends, the squeezing rod 10 will be driven down. The squeezing rod 10 will come into contact with the two clamping rods 8 and squeeze the two clamping rods 8 to move toward each other. The pressure spring 9 will be compressed. At the same time, the two clamping rods 8 will clamp the lampshade 21, thereby strengthening the position limitation of the lampshade 21, making the lampshade 21 clamped more firmly and improving the processing quality. When the lampshade 21 is processed, the squeezing rod 10 will reset upward and disengage from the two clamping rods 8. The reset of the pressure spring 9 will drive the clamping rod 8 to reset.

[0026] When the staff places the lampshade 21 on the base 1, the lampshade 21 can be positioned through the positioning plate 13 to improve work efficiency. After the holes of the lampshade 21 are trimmed, the staff presses the rocker arm 11, the torsion spring 12 is twisted, and the rocker arm 11 swings to lift the lampshade 21, making it more convenient and quick for the staff to replace the lampshade 21.
