Abstract
Description
Technical Field
[0001] This utility model belongs to the field of silicone rubber frame processing technology, specifically a cutting device for processing silicone rubber frames. Background Technology
[0002] Silicone rubber frames, with their advantages of high temperature resistance, aging resistance, good elasticity, and strong sealing performance, are widely used in electronic equipment (such as sensor and display sealing), medical devices (such as frames for sterilization equipment), and automotive parts (such as waterproof and dustproof frames). During the production of silicone rubber frames, a cutting device is required to cut them. Existing cutting devices typically cut the silicone rubber frame directly through the cutting head, requiring the frame to be held and fixed during cutting. This can cause the frame to move with the cutting tool, resulting in an uneven cut surface. Furthermore, when cutting other edges or corners, the frame needs to be repositioned, which can easily lead to errors. Utility Model Content
[0003] To overcome the above-mentioned defects, this utility model provides a cutting device for processing silicone rubber frames. It solves the problems that when using the cutting device, the silicone rubber frame is usually cut directly by the cutting head, which requires holding the silicone rubber frame to fix it during cutting. The silicone rubber frame may move with the cutting tool during the cutting process, resulting in an uneven cutting surface. Moreover, when other edges and corners of the silicone rubber frame need to be cut, the silicone rubber frame needs to be rearranged, which is prone to errors.
[0004] To achieve the above objectives, this utility model provides the following technical solution: a cutting device for processing silicone rubber frames, comprising a base, a placement platform rotatably connected to the top of the base, two fixed plates symmetrically fixed to the bottom of the placement platform, a motor fixedly connected to one side of one of the fixed plates, the motor having a bidirectional threaded rod provided through an output shaft, the bidirectional threaded rod being rotatably connected to the fixed plate through bearings, two limiting rods fixedly connected between the two fixed plates on both sides of the bidirectional threaded rod, movable blocks threadedly connected to both ends of the bidirectional threaded rod between the two fixed plates, the movable blocks being slidably connected to the limiting rods, an mounting plate fixedly connected to the top of the movable blocks, two sliding grooves opened on the top of the mounting plate, limiting blocks being slidably connected inside the sliding grooves, a connecting rod fixedly connected to the top of the limiting blocks, a positioning block fixedly connected to the top of the connecting rod, and four guide grooves opened on the top of the placement platform, the inner walls of the guide grooves being slidably connected to the connecting rods.
[0005] As a further embodiment of this utility model: four limiting grooves are provided at equal angles on the top of the placement platform, and a fixing frame is fixedly connected to one side of the top of the base.
[0006] As a further embodiment of this utility model: a screw rod is threaded through the top of the fixing frame, and a plug is installed at the bottom of the screw rod through the fixing frame, the plug being positioned corresponding to the limiting groove.
[0007] As a further embodiment of this utility model: the top of the insert block is fixedly connected to the slide rods on both sides of the screw, and the slide rods are slidably connected to the fixing frame through it.
[0008] As a further embodiment of this utility model: the base is fixedly connected to the inner wall on both sides of the placement platform with two electric telescopic rods, one end of the two electric telescopic rods is fixedly connected to the same support frame, and the support frame is slidably connected to the base.
[0009] As a further embodiment of this utility model: two electric push rods are fixedly connected to the top of the support frame, and a lifting plate is fixedly connected to the bottom of the electric push rods through the support frame. Slider blocks are fixedly connected to both sides of the lifting plate.
[0010] As a further embodiment of this utility model: two limiting frames are symmetrically fixedly connected to the inner wall of the support frame, and the limiting frames are slidably connected to the slider inside.
[0011] As a further embodiment of this utility model: four movable rods are slidably connected through the four corners of the bottom of the lifting plate, and the bottom of the four movable rods are fixedly connected to the same cutting seat through the lifting plate. A spring is sleeved on the surface of the movable rods located between the lifting plate and the cutting seat.
[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This cutting device for processing silicone rubber frames comprises a motor, a bidirectional threaded rod, a movable block, and a positioning block. The motor drives the bidirectional threaded rod to rotate via its output shaft, allowing it to slide between two fixed plates. This, in turn, causes the movable block to slide between the two fixed plates. The mounting plate on top of the movable block then drives a limiting block to slide at the top of a groove. This limiting block, in turn, causes a connecting rod and the positioning block to slide together. The guide groove guides the connecting rod, allowing it to position the positioning block against the four corners inside the silicone rubber frame. This facilitates stable cutting of the silicone rubber frame. The rotating placement table allows the silicone rubber frame to rotate, facilitating cutting of other surfaces of the frame and reducing cutting errors.
[0013] 2. The cutting device for processing silicone rubber frames includes an electric telescopic rod, a support frame, a lifting plate, and a cutting seat. The electric telescopic rod pushes the support frame to move, causing the support frame to adjust the position of the cutting seat. The electric push rod moves the lifting plate, allowing the lifting plate to move the cutting seat and spring together downwards. After the cutting seat touches the surface of the silicone rubber frame, the electric push rod continues to push and compress the spring, causing the cutting seat to move downwards through the spring's elastic force, thus stabilizing the cutting seat to cut the silicone rubber frame.

[0015] The technical solution of this patent will be further described in detail below with reference to specific embodiments.
[0016] like Figure 1-4 As shown, this utility model provides a technical solution: a cutting device for processing silicone rubber frames, including a base 1, a placement platform 2 rotatably connected to the top of the base 1, four limiting grooves 14 equally spaced on the top of the placement platform 2, a fixing frame 15 fixedly connected to one side of the top of the base 1, a screw 16 threadedly connected to the top of the fixing frame 15, and an insert 17 installed at the bottom of the screw 16 through the fixing frame 15. The insert 17 is positioned corresponding to the limiting grooves 14. By setting the screw 16, the screw 16 can drive the insert 17 to move downward, so that the insert 17 can be inserted into the limiting grooves 14, thereby limiting the placement platform 2 and improving the stability of cutting the silicone rubber frame on the top of the placement platform 2. The top of the insert 17 is fixedly connected to the two sides of the screw 16. The slide rod 18 is slidably connected to the fixing frame 15. By setting the slide rod 18, the screw 16 drives the insert 17 to move, so that the slide rod 18 at the top of the insert 17 slides inside the fixing frame 15. Thus, the fixing frame 15 can limit the insert 17 through the slide rod 18, so that the insert 17 can be stably inserted into the limiting groove 14. The base 1 is located on the inner wall of both sides of the placement platform 2 and has two electric telescopic rods 19 fixedly connected. One end of the two electric telescopic rods 19 is fixedly connected to the same support frame 20. The support frame 20 is slidably connected to the base 1. By setting the electric telescopic rods 19, the electric telescopic rods 19 can drive the support frame 20 to move, thereby realizing the position adjustment of the support frame 20 and the cutting seat 26, which makes it convenient for the cutting seat 26 to cut silicone rubber frames of different specifications. Two electric push rods 22 are fixedly connected to the top of the support frame 20. The bottom of the electric push rods 22 passes through the support frame 20 and is fixedly connected to the lifting plate 23. Slider 24 is fixedly connected to both sides of the lifting plate 23. By setting the electric push rods 22, the electric push rods 22 drive the lifting plate 23 to move down, so that the lifting plate 23 can drive the cutting seat 26 to cut the silicone rubber frame. Two limiting frames 21 are symmetrically fixedly connected to the inner wall of the support frame 20. The inside of the limiting frame 21 is slidably connected to the slider 24. By setting the limiting frame 21, when the lifting plate 23 moves, it drives the slider 24 to slide inside the limiting frame 21, so that the limiting frame 21 can limit the lifting plate 23 through the slider 24, thereby allowing the lifting plate 23 to stably drive the cutting seat 26 to move. Four movable rods 25 are slidably connected through the four corners of the bottom of the lifting plate 23. The bottom of the four movable rods 25 passes through the lifting plate 23 and is fixedly connected to the same cutting seat 26. A spring 27 is sleeved on the surface of the movable rod 25 between the lifting plate 23 and the cutting seat 26. By setting the spring 27, the cutting seat 26 presses against the edge of the silicone rubber frame to perform cutting processing. At the same time, the cutting seat 26 squeezes the spring 27, so that the spring 27 generates a relative elastic force. Thus, after the cutting seat 26 completes the cutting, the spring 27 can drive the cutting seat 26 to return to its original position through the elastic force. Two fixed plates 3 are symmetrically fixedly connected to the bottom of the placement platform 2. A motor 4 is fixedly connected to one side of one of the fixed plates 3. The motor 4 is provided with a bidirectional threaded rod 5 through the output shaft. The bidirectional threaded rod 5 is rotatably connected to the fixed plate 3 through a bearing. Two limit rods 6 are fixedly connected between the two fixed plates 3 on both sides of the bidirectional threaded rod 5. By setting the limit rods 6, the bidirectional threaded rod 5 drives the movable block 7 to move. At the same time, the movable block 7 slides outside the limit rods 6, so that the limit rods 6 can limit the movement of the movable block 7, so that the movable block 7 can stably drive the installation plate 8 to move. The two-way threaded rod 5 is located between two fixed plates 3, with movable blocks 7 threaded through both ends. The movable blocks 7 are slidably connected to the limiting rod 6. The top of the movable blocks 7 is fixedly connected to the mounting plate 8. The top of the mounting plate 8 has two sliding grooves 9. The sliding grooves 9 are slidably connected to the limiting blocks 10. The top of the limiting blocks 10 is fixedly connected to the connecting rod 11. The top of the connecting rod 11 is fixedly connected to the positioning block 12. The top of the placement platform 2 has four guide grooves 13. The inner wall of the guide grooves 13 is slidably connected to the connecting rod 11. When the guide grooves 13 guide the connecting rod 11 by setting the sliding grooves 9, the limiting block 10 at the bottom of the connecting rod 11 slides inside the sliding grooves 9. This allows the sliding grooves 9 to limit the movement of the connecting rod 11 and the positioning block 12 through the limiting block 10, so that the positioning block 12 can stably limit and fix the silicone rubber frame.
[0017] The working principle of this utility model is as follows: Place the silicone rubber frame on top of the placement platform 2, start the motor 4. The motor 4 drives the bidirectional threaded rod 5 to rotate through the output shaft, allowing the bidirectional threaded rod 5 to move the movable block 7 between the two fixed plates 3. The movable block 7, through the mounting plate 8, causes the limiting block 10 and the connecting rod 11 to slide. Under the guidance of the guide groove 13, the connecting rod 11 moves the positioning block 12 toward the silicone rubber frame until the positioning block 12 abuts against the inside of the silicone rubber frame, thus fixing the silicone rubber frame in place. Start the electric telescopic rod 19, which moves the support frame 20 to adjust the position of the support frame 20 and the cutting seat 26. The electric push rod 22 is activated, which drives the lifting plate 23 to move. The lifting plate 23 can simultaneously drive the cutting seat 26 and the spring 27. The cutting seat 26 abuts against the top of the silicone rubber frame. As the lifting plate 23 moves down, it compresses the spring 27 and simultaneously drives the movable rod 25 to slide inside the lifting plate 23, thereby buffering the cutting process of the silicone rubber frame. After the cutting is completed, the electric push rod 22 drives the cutting seat 26 to move up and rotates the screw 16. The screw 16 drives the insert block 17 to move out of the slide groove 9, thereby rotating the placement table 2 and driving the silicone rubber frame to rotate together, which facilitates the cutting and processing of different edges and corners of the silicone rubber frame.
