[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0017] Example: Figure 1-3As shown, this utility model provides a thick sheet vacuum forming auxiliary cutting device, including a base frame 1. A moving mechanism 3 is fixedly mounted on the upper surface of the base frame 1. Two symmetrically distributed fixing mechanisms 2 are fixedly mounted on the upper surface of the moving mechanism 3. A cutting device 4 is mounted above the moving mechanism 3. One side of the cutting device 4 is fixedly connected to the base frame 1. The fixing mechanism 2 includes a fixing frame 20. One side of the fixing frame 20 is fixedly connected to the moving mechanism 3. A cylinder 22 is mounted on one side of the fixing frame 20. A moving plate 23 is fixedly mounted at the output end of the cylinder 22. A rotating frame 24 is fixedly mounted at one end of the moving plate 23. A pull rod 27 is rotatably mounted on the inner side of the rotating frame 24. A fixing clamp 28 is rotatably mounted at one end of the pull rod 27. The middle part of the fixing clamp 28 is rotatably connected to the upper end of the fixing frame 20. Through the fixing mechanism 2, when it is necessary to fix the thick sheet vacuum forming material to be cut, the thick sheet vacuum forming material is first placed on the sliding plate 32, and then... When cylinder 22 starts working, its output end pushes the moving plate 23 upward. As the moving plate 23 moves, the rotating frame 24 fixedly connected to one end of it also moves. At this time, the pull rod 27 rotating inside the rotating frame 24 starts to rotate around the axis of the rotating groove 29 due to its rotational connection with the rotating groove 29, thereby driving one end of the fixed clamping plate 28 to lift upward. Since the middle part of the fixed clamping plate 28 is rotatably connected to the upper end of the fixed frame 20, the other end of the fixed clamping plate 28 will move downward, realizing the clamping of the thick sheet of vacuum forming material. When cylinder 22 stops working, the fixed clamping plate 28 maintains the clamping state through its own gravity and the reaction force of the material, ensuring the stability of the material during the cutting process. In addition, the rotating frame 24 slides with the moving slide rail 26 on the fixed frame 20 through the moving slider 25, making the rotating frame 24 more stable during movement and further improving the clamping accuracy.
[0018] A support frame 21 is fixedly mounted on the lower surface of the fixed frame 20. One side of the support frame 21 is fixedly connected to the cylinder 22. A rotating groove 29 is opened on one side of the rotating frame 24. The rotating groove 29 is rotatably connected to the lower end of the pull rod 27. A movable slider 25 is fixedly mounted on one side of the rotating frame 24. A movable slide rail 26 is fixedly mounted on the inner wall of one side of the fixed frame 20. The movable slide rail 26 and the movable slider 25 are slidably engaged. The rotating frame 24 is more stable during movement by sliding the movable slider 25 with the movable slide rail 26 on the fixed frame 20, which further improves the accuracy of clamping.
[0019] The moving mechanism 3 includes a moving frame 30, the lower surface of which is fixedly connected to the base frame 1. A motor 34 is provided on one side of the moving frame 30, and a threaded rod 37 is fixedly provided at the output end of the motor 34. Two positioning frames 38 are fixedly provided on the lower inner wall of the moving frame 30, and the positioning frames 38 are rotatably connected to the threaded rod 37. A sliding block 36 is threadedly sleeved on the outer side of the threaded rod 37, and a sliding plate 32 is fixedly provided on the upper surface of the sliding block 36. One side of the sliding plate 32 is fixedly connected to the fixing mechanism 2. When movement is required through the moving mechanism 3, the motor 34 starts to work, and its output end drives the threaded rod 37 to rotate. Since the threaded rod 37 is threadedly sleeved with the sliding block 36, the rotation of the threaded rod 37 is converted into the linear movement of the sliding block 36. A sliding plate 32 is fixedly provided on the surface, so the sliding plate 32 will also move with the movement of the sliding block 36. At the same time, the sliding slider 33 on the lower surface of the sliding plate 32 slides and engages with the sliding rail 39 on the upper surface of the moving frame 30, ensuring the stability and accuracy of the sliding plate 32 during movement. When the sliding plate 32 moves to the bottom of the cutting device 4, the motor 34 stops working. At this time, the thick sheet of vacuum forming material on the fixing mechanism 2 is within the cutting range of the cutting device 4, waiting for the cutting operation. The cutting device 4 is a conventional technical means in the field and can be flexibly replaced according to actual needs. The anti-slip pad 31 increases the friction between the sliding plate 32 and the clamped material, preventing the material from sliding or displacing during the cutting process.
[0020] A mounting bracket 35 is fixedly provided on one side of the movable frame 30. One side of the mounting bracket 35 is fixedly engaged with the motor 34. Two symmetrically distributed sliding rails 39 are fixedly provided on the upper surface of the movable frame 30. Multiple sliding sliders 33 distributed in a rectangular array are fixedly provided on the lower surface of the sliding plate 32. The sliding sliders 33 are slidably engaged with the sliding rails 39. An anti-slip pad 31 is fixedly provided on the upper surface of the sliding plate 32. The sliding sliders 33 on the lower surface of the sliding plate 32 are slidably engaged with the sliding rails 39 on the upper surface of the movable frame 30, ensuring the stability and accuracy of the sliding plate 32 during movement. The anti-slip pad 31 increases the friction between the sliding plate 32 and the clamped material, preventing the material from sliding or displacing during the cutting process.
[0021] Working principle: When a thick sheet of vacuum forming material needs to be fixed using the fixing mechanism 2, the material is first placed on the sliding plate 32. Then, the cylinder 22 starts working, its output pushing the moving plate 23 upwards. As the moving plate 23 moves, the rotating frame 24, fixedly connected to one end, also moves. At this time, the pull rod 27 rotating inside the rotating frame 24, due to its rotational connection with the rotating groove 29, begins to rotate around the axis of the rotating groove 29, thereby lifting one end of the fixing clamp 28 upwards. The middle part of the fixed clamping plate 28 is rotatably connected to the upper end of the fixed frame 20, so the other end of the fixed clamping plate 28 will move downward to clamp the thick sheet of vacuum forming material. When the cylinder 22 stops working, the fixed clamping plate 28 maintains the clamping state through its own gravity and the reaction force of the material, ensuring the stability of the material during the cutting process. In addition, the rotating frame 24 slides with the moving slide rail 26 on the fixed frame 20 through the moving slider 25, making the rotating frame 24 more stable during movement and further improving the accuracy of clamping.
[0022] When movement is required via the moving mechanism 3, the motor 34 starts working, and its output end drives the threaded rod 37 to rotate. Since the threaded rod 37 is threadedly fitted with the sliding block 36, the rotation of the threaded rod 37 is converted into the linear movement of the sliding block 36. The upper surface of the sliding block 36 is fixedly provided with a sliding plate 32, so the sliding plate 32 also moves with the movement of the sliding block 36. At the same time, the sliding slider 33 on the lower surface of the sliding plate 32 slides and engages with the sliding rail 39 on the upper surface of the moving frame 30, ensuring the stability and accuracy of the sliding plate 32 during movement. When the sliding plate 32 moves to below the cutting device 4, the motor 34 stops working. At this time, the thick sheet of vacuum forming material on the fixing mechanism 2 is within the cutting range of the cutting device 4, waiting for the cutting operation. The cutting device 4 is a conventional technical means in the field and can be flexibly replaced according to actual needs. The anti-slip pad 31 increases the friction between the sliding plate 32 and the clamped material, preventing the material from sliding or displacing during the cutting process.
