Detailed Implementation

[0022] 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.

[0023] Please see Figure 1-4 This utility model provides a technical solution: a cutting device for isostatic graphite, including a processing table 1, two sets of rodless cylinders 2 are installed on both sides of the top of the processing table 1, a support base 3 is connected to the top of the rodless cylinder 2, a support plate 4 is fixedly installed on the top of the support base 3, a telescopic rod 5 is connected to one side of the support plate 4, a clamp 6 is provided at the corresponding position on one side of the telescopic rod 5, and a disassembly and assembly component for installing or disassembling the clamp 6 is provided between one side of the clamp 6 and the telescopic end of the telescopic rod 5.

[0024] Preferably, the assembly / disassembly components include: a connecting rod 7, a connecting pipe 8, and a limiting mechanism. The connecting rod 7 is rotatably connected to one side of the clamp 6, and the connecting pipe 8 is fixedly installed at the telescopic end of the telescopic rod 5. The interior of the connecting pipe 8 is adapted to the connecting rod 7, and the surface of the connecting rod 7 is threadedly connected to the inner wall of the connecting pipe 8. Axial force is transmitted by a screw pair, and the clamp 6 is fixed by generating a preload force through tightening. A limiting mechanism for limiting the connecting rod 7 is provided between the connecting rod 7 and the connecting pipe 8.

[0025] Specifically, through the coordinated use of connecting rod 7, connecting pipe 8, and limiting mechanism, connecting rod 7 and connecting pipe 8 are fixed by screwing them together, and then the limiting mechanism is used to mechanically lock them together. The clamp 6 at one end of connecting rod 7 can be installed, and vice versa, the clamp 6 can be disassembled. This allows for quick assembly and disassembly between clamp 6 and telescopic rod 5, supports quick switching between different specifications of clamp 6, adapts to various graphite billet shapes, and facilitates the replacement of damaged clamp 6 or connecting rod 7 without disassembling the entire telescopic mechanism, thus reducing maintenance costs.

[0026] Preferably, the limiting mechanism includes: a limiting block 9, a limiting rod 10, a telescopic spring 11, and a limiting hole 12. The limiting block 9 is fixedly installed on the surface of the connecting pipe 8. The limiting rod 10 is slidably connected inside the limiting block 9. The telescopic spring 11 is connected to one end of the surface of the limiting rod 10 and inside the limiting block 9. One end of the telescopic spring 11 is connected to the inner wall of one end of the limiting block 9. The limiting hole 12 is opened through the surface of the connecting rod 7. The interior of the limiting hole 12 is adapted to one end of the limiting rod 10, and one end of the limiting rod 10 is inserted into the inner cavity of the limiting hole 12. The limiting rod 10 is inserted into the limiting hole 12 under the pressure of the telescopic spring 11, forming a physical block to prevent the thread from rotating in the opposite direction and loosening due to vibration or impact. It can also form a redundant design. Even if the thread is worn, the limiting rod 10 can still provide mechanical anti-reverse, avoiding the sudden fall of the clamp 6 and causing a safety accident.

[0027] Preferably, a cutting blade 13 is provided at one end of the top of the processing table 1. The cutting blade 13 is connected to a rotating shaft 14. Rotating seats 15 are adapted to be connected to both ends of the surface of the rotating shaft 14. One end of the rotating shaft 14 passes through a set of rotating seats 15 and is connected to a drive assembly for driving the rotating shaft 14. A mounting bracket 16 is connected to the surface of the rotating seat 15. The upper end of the mounting bracket 16 is fixed to the inner wall of the upper end of the processing table 1 by bolts. The rotating shaft 14 is fixed to the mounting bracket 16 through the rotating seats 15 at both ends, forming a symmetrical support structure. To eliminate shaft deflection caused by unilateral cantilever and ensure that the rotational concentricity error of the cutting blade 13 is reduced, the mounting bracket 16 is rigidly connected to the processing table 1 by bolts, which evenly distributes the cutting load to the frame of the processing table 1 and resists the torsional vibration caused by the cutting reaction force. The bolt holes of the mounting bracket 16 are elongated openings, which allow the rotating seat 15 to be finely adjusted within an appropriate range to compensate for the cumulative installation error between the processing table 1 and the rotating shaft 14. By adjusting the tightness of the bolts, the center line of the cutting blade 13 and the workpiece of the fixture 6 can be quickly aligned.

[0028] Preferably, the drive assembly includes: a drive motor 17, a first pulley 18, a belt 19, and a second pulley 20. The drive motor 17 is mounted on the inner wall of the upper end of the processing table 1. The output end of the drive motor 17 is fixedly connected to the first pulley 18. The belt 19 is fitted onto the surface of the first pulley 18. The second pulley 20 is fixedly mounted on the surface of one end of the rotating shaft 14. The surface of the second pulley 20 is fitted onto the belt 19, and the second pulley 20 is connected to the first pulley 18 via the belt 19. The drive motor 17 is mounted via a slide rail, allowing for adjustable mounting position. By controlling the tension of belt 19, the life of belt 19 is extended. Belt 19 transmits power through friction. When the cutting resistance suddenly increases, belt 19 can slip briefly to prevent drive motor 17 from stalling and burning out or mechanical parts from being overloaded and damaged, thus acting as a mechanical fuse. The elasticity of belt 19 can also absorb the instantaneous vibration generated by the start-up and stop of drive motor 17 and cutting impact, reducing the vibration amplitude transmitted to processing table 1. By adjusting the diameter ratio of the first pulley 18 to the second pulley 20, the rotational speed range of cutting blade 13 can be flexibly adjusted to meet the cutting needs of graphite of different thicknesses.
