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.

[0023] Reference Figure 1 - Figure 3, the utility model provides an embodiment: a protective device for machining a generator rotor, comprising a base 1, a protective shell 3 is arranged on the top of the base 1, a rectangular array of card slots 6 is arranged on the bottom of the protective shell 3, a rectangular array of fixed columns 7 are fixedly connected to the top of the base 1, a rectangular array of wedge-shaped slide bars 11 are slidably connected to one side of the base 1, a threaded column 12 is rotatably connected to one side of the wedge-shaped slide bar 11, an outer wall of the threaded column 12 is threadedly connected to the base 1, a rectangular array of wedge-shaped slide bars 9 are slidably connected to one side of the base 1, a limiting groove 10 is arranged on one side of the wedge-shaped slide bar 9, both sides of the fixed column 7 are rotatably connected, a spring 8 is arranged inside the fixed column 7, one end of the spring 8 is fixedly connected to the top of the wedge-shaped slide bar 9, and the other end of the spring 8 is fixedly connected to the inner wall of the fixed column 7;

[0024] Specifically, when the threaded column 12 rotates, it will drive the wedge-shaped slide bar 11 to slide, so that it can lift the wedge-shaped slide bar 9 when sliding. In this process, the limiting groove 10 opened inside the wedge-shaped slide bar 9 promotes the rotation of the movable clamp 21 by contacting one side of the movable clamp 21 set inside the fixed column 7. As the movable clamp 21 rotates, its other side will be pressed down and clamped in the slot 6 set inside the protective shell 3, thereby fixing the protective shell 3.

[0025] Reference Figure 1 A heat dissipation component is disposed inside the base 1, and the heat dissipation component includes a heat dissipation slot 2, and the heat dissipation slot 2 is opened on one side inside the base 1;

[0026] Specifically, a heat dissipation groove 2 is provided inside the base 1 , and the heat dissipation groove 2 can prevent the generator rotor from overheating during machining, thereby effectively preventing the danger of machining due to overheating.

[0027] Reference Figure 1 and Figure 4 A motor 13 is fixedly connected to one side of the interior of the protective shell 3, and a positive and negative screw rod 14 is fixedly connected to the output end of the motor 13. One side of the outer wall of the positive and negative screw rod 14 is rotatably connected to the interior of the protective shell 3. Both sides of the outer wall of the positive and negative screw rod 14 are threadedly connected to driving blocks 15. A connecting rod 17 is fixedly connected to the bottom of the driving block 15. The bottom of the connecting rod 17 is fixedly connected to the door frame 4. A fixing rod 19 is fixedly connected to one side of the top of the door frame 4. A slide groove 16 is opened on one side of the interior of the protective shell 3. A roller 18 is rotatably connected to one side of the outer wall of the fixing rod 19. The outer wall of the roller 18 is slidably connected to the interior of the slide groove 16. Slide grooves 20 are opened on both sides of the interior of the protective shell 3. The outer wall of the door frame 4 is slidably connected to the interior of the slide groove 20. An acrylic plate 5 is fixedly connected to the interior of the door frame 4.

[0028] Specifically, the rotational power of the motor 13 is transmitted to the forward and reverse screw rods 14. When the forward and reverse screw rods 14 rotate, the driving blocks 15 on both sides can generate relative linear motion. The driving blocks 15 are connected to the door frame 4 through the connecting rod 17. Therefore, when the driving blocks 15 move, the door frame 4 will also move accordingly. In order to ensure the smooth movement of the door frame 4, the roller 18 on the fixed rod 19 is designed to roll inside the slide groove 16. This roller 18 design effectively reduces friction, so that the door frame 4 can easily slide out or slide into the slide groove 20. In this process, the protective shell 3 is opened and closed accordingly. An acrylic plate 5 is also provided inside the door frame 4, which allows people to clearly observe the situation inside the protective shell 3 when the door frame 4 is closed, thereby realizing real-time monitoring of the internal environment.

[0029] Working principle: When the protective shell 3 is fixed, the rotation of the threaded column 12 can drive the wedge-shaped slide bar 2 11 to slide, and the wedge-shaped slide bar 2 11 can lift the wedge-shaped slide bar 1 9. At this time, the limit groove 10 opened inside the wedge-shaped slide bar 1 9 will push one side of the movable clamp 21 set inside the fixed column 7, so that the movable clamp 21 rotates, and the other side of the movable clamp 21 will press down and clamp in the card slot 6 set inside the protective shell 3, so that the protective shell 3 is fixed. When the generator rotor is put in and taken out, When the motor 13 drives the forward and reverse screw rods 14 to rotate, the forward and reverse screw rods 14 will drive the driving blocks 15 on both sides to move relative to each other, so that the driving blocks 15 drive the door frame 4 to move through the connecting rod 17, and the door frame 4 also rolls inside the slide groove 16 by the roller 18 on the fixed rod 19, thereby assisting the door frame 4 to slide out or slide into the slide groove 20, so that the protective shell 3 is opened and closed, and an acrylic plate 5 is arranged inside the door frame 4 to facilitate observation of the inside of the protective shell 3 when the door frame 4 is closed.
