Description

Technical Field

[0001] This utility model relates to the field of grinding disc processing technology, and more specifically, to a grinding disc cutting device. Background Technology

[0002] In the field of grinding disc processing, traditional cutting equipment generally suffers from insufficient cutting precision, complex operation, and poor protective effects, making it difficult to meet the demands of modern industry for efficient, precise, and safe processing. Existing technologies often employ a single motor to drive the cutting blade assembly for linear cutting, which makes it difficult to achieve precise control of complex trajectories, resulting in uneven cutting edges and affecting the quality and efficiency of subsequent grinding processes.

[0003] In addition, the protective devices of traditional equipment are mostly fixed or manually operated, and cannot be synchronized with the cutting action. This increases the labor intensity of operators and poses a safety hazard due to untimely protection. In particular, the problem of flying debris generated during the cutting process is that traditional equipment often adopts a completely enclosed design. Although it can play a protective role, it seriously hinders the operator's real-time observation and adjustment of the cutting status and reduces work efficiency. Therefore, in order to address the above technical problems, a grinding disc cutting device is proposed here. Utility Model Content

[0004] The purpose of this invention is to provide a grinding disc cutting device that uses a motor to drive a lead screw and a rotating shaft to achieve simultaneous cutting and protection. During cutting, the lifting block drives the cutting blade assembly to move down and rotate precisely, forming a circumferential cutting trajectory. This quickly processes the grinding disc into a circular disc shape, facilitating subsequent processing. At the same time, the rotating shaft releases a pull rope to automatically unfold the baffle for protection. After cutting, the baffle automatically resets. This device combines efficient cutting with safety protection, and is easy to operate and provides intuitive observation.

[0005] This utility model is achieved through the following technical solution:

[0006] A grinding disc cutting device includes an operating table. A vertical plate is fixedly connected to the upper side of the operating table. A lifting groove is formed on the outside of the vertical plate. A first motor is fixedly connected to the upper side of the lifting groove. A lead screw is fixedly connected to the bottom of the first motor. A lifting block is threaded onto the outside of the lead screw. A mounting base is fixedly connected to the outside of the lifting block. A rotating mechanism is mounted on the outside of the mounting base. A cutting mechanism is mounted on the bottom of the mounting base. A baffle is slidably connected to the upper side of the operating table. Tempered glass is formed on the outside of the baffle. A retracting mechanism is installed inside the operating table.

[0007] Preferably, a clamping platform is fixedly connected to the upper side of the operating table, and the clamping platform is located directly below the mounting base.

[0008] Preferably, the lead screw is rotatably connected to the inner side of the lifting groove, and the lifting block is limited and slidably connected to the inside of the lifting groove.

[0009] Preferably, the rotating mechanism includes a second motor, a rotating rod, and a rotating disk. The second motor is fixedly connected to the upper side of the mounting base, the rotating rod is fixedly connected to the lower side of the second motor and rotatably connected to the inner side of the mounting base, and the rotating disk is fixedly connected to the bottom of the rotating rod, with a sliding connection between the rotating disk and the lower side of the mounting base.

[0010] Preferably, the cutting mechanism includes a fixed base, a third motor, and a cutting blade assembly. The fixed base is fixedly connected to the bottom of the rotating disk, the cutting blade assembly is rotatably connected to the inner side of the fixed base, and a portion of the cutting blade assembly protrudes from the bottom of the fixed base. The third motor is fixedly connected to the outside of the fixed base.

[0011] Preferably, the retraction mechanism includes a rotating shaft, a pull rope, a mounting plate, and a compression spring. The rotating shaft is fixedly connected to the bottom of the lead screw, and the rotating shaft is rotatably connected to the upright plate and the operating table. The mounting plate is fixedly connected to the inner side of the operating table, and there are two sets of mounting plates arranged symmetrically. The mounting plate is installed on the lower side of the baffle.

[0012] Preferably, there are two sets of pull ropes, which are fixedly connected and wound around the outside of the rotating shaft. The ends of the two sets of pull ropes pass through the mounting plate and are fixedly connected to the lower side of the baffle. The compression spring is fixedly connected between the mounting plate and the baffle, and is sleeved on the outside of the pull rope. The compression spring is always in a compressed state.

[0013] The technical solution of this utility model has at least the following beneficial effects:

[0014] This utility model proposes a grinding disc cutting device. During the cutting process, a first motor drives a lead screw to precisely lower a lifting block, while a third motor drives the cutting blade assembly to rotate at high speed. Combined with a rotating disk driven by a second motor, this creates a continuous circular motion in the cutting trajectory, quickly cutting the grinding disc into a standard circular disc structure. This ensures smooth cutting edges and optimizes the adaptability of subsequent grinding processes. Furthermore, as the lead screw descends, it releases a pull rope from the rotating shaft, causing a baffle to automatically unfold under the action of a compression spring, forming a protective barrier around the cutting area. This effectively prevents debris from flying everywhere, and the tempered glass on the baffle allows for real-time observation of the cutting status, balancing protection and ease of operation. After cutting, the lead screw reverses, causing the baffle to automatically reset, and the compression spring compresses and stores energy. This not only improves processing accuracy and efficiency but also eliminates the cumbersome steps of manually operating the protective device, ensuring continuous safety isolation and providing operators with a more convenient and safer working experience.

[0026] A clamping platform 2 is fixedly connected to the upper side of the operating table 1, and the clamping platform 2 is located directly below the mounting base 8. A clamp is installed on the clamping platform 2, which can clamp grinding discs of various shapes.

[0027] The lead screw 6 is rotatably connected to the inside of the lifting groove 4, and the lifting block 7 is limited and slidably connected to the inside of the lifting groove 4. The design of the lifting groove 4 ensures the stable movement of the lifting block 7 in the vertical direction and avoids deviation.

[0028] The rotating mechanism includes a second motor 9, a rotating rod 10, and a rotating disk 11. The second motor 9 is fixedly connected to the upper side of the mounting base 8, the rotating rod 10 is fixedly connected to the lower side of the second motor 9, and the rotating rod 10 is rotatably connected to the inner side of the mounting base 8. The rotating disk 11 is fixedly connected to the bottom of the rotating rod 10, and the rotating disk 11 is slidably connected to the lower side of the mounting base 8. The rotation of the rotating disk 11 drives the cutting mechanism to achieve a circumferential cutting trajectory, thereby improving the cutting accuracy.

[0029] The cutting mechanism includes a fixed base 12, a third motor 13, and a cutting blade assembly 14. The fixed base 12 is fixedly connected to the bottom of the rotating disk 11, and the cutting blade assembly 14 is rotatably connected to the inner side of the fixed base 12. A portion of the cutting blade assembly 14 protrudes from the bottom of the fixed base 12. The third motor 13 is fixedly connected to the outside of the fixed base 12. The third motor 13 drives the cutting blade assembly 14 to rotate at high speed to ensure cutting efficiency and quality.

[0030] The retraction mechanism includes a rotating shaft 17, a pull rope 18, a mounting plate 19, and a compression spring 20. The rotating shaft 17 is fixedly connected to the bottom of the lead screw 6, and the rotating shaft 17 is rotatably connected to the upright plate 3 and the operating table 1. The mounting plate 19 is fixedly connected to the inner side of the operating table 1, and there are two sets of mounting plates 19 arranged symmetrically. The mounting plate 19 is installed on the lower side of the baffle 15 and provides a guiding function for the pull rope 18.

[0031] There are two sets of pull ropes 18, which are fixedly connected and wound around the outside of the rotating shaft 17. The ends of the two sets of pull ropes 18 pass through the mounting plate 19 and are fixedly connected to the lower side of the baffle 15. The compression spring 20 is fixedly connected between the mounting plate 19 and the baffle 15, and the compression spring 20 is sleeved on the outside of the pull ropes 18. The compression spring 20 is always in a compressed state. The elasticity of the compression spring 20 ensures that the baffle 15 can be quickly unfolded and stably protected during the cutting process.

[0032] The working principle of a grinding disc cutting device based on an embodiment is as follows: During the cutting process, the operator first securely clamps the grinding disc to be processed onto the clamping table 2. The first motor 5 drives the lead screw 6 to rotate, causing the threaded lifting block 7 to move vertically downwards along the lifting groove 4 of the vertical plate 3. This allows the mounting base 8, carrying the cutting mechanism, to descend precisely. At the same time, the third motor 13 starts synchronously, driving the cutting blade assembly 14 to rotate at high speed to cut the grinding disc. Simultaneously, during the cutting process, the second motor 9 drives the rotating rod 10 to rotate the rotating disk 11 axially. Through the linkage between the fixed base 12 and the cutting blade assembly 14, the cutting trajectory forms a continuously changing circular motion, thereby quickly cutting the flat grinding disc into a standard circular disk structure. This ensures the smoothness of the cutting edge and improves the processing adaptability of subsequent grinding processes, significantly optimizing the overall processing efficiency. Furthermore, while performing the cutting operation, when the lead screw 6 rotates forward, causing the lifting block 7 to move downwards, its bottom connection... The rotating shaft 17 rotates synchronously, gradually releasing the two sets of pull ropes 18 wound around it. At this time, the baffle 15 extends outward along the preset slide rail of the operating table 1 under the elastic restoring force of the compression spring 20, forming a protective barrier around the cutting area. The tempered glass 16 on the surface of the baffle 15 serves as an observation window, allowing the operator to monitor the internal cutting status in real time. This effectively blocks the flying debris generated during the cutting process and avoids the drawbacks of traditional enclosed protection affecting visual monitoring. After the cutting operation is completed, during the process of the screw 6 rotating in the reverse direction to lift the lifting block 7, the rotating shaft 17 synchronously reverses to rewind and retract the pull ropes 18, and pulls the baffle 15 to smoothly reset and be stored inside the operating table 1. At the same time, the compression spring 20 is compressed and stored, preparing for the deployment of protection for the next cutting operation. This automatic protection mechanism linked to the cutting action eliminates the cumbersome steps of manually operating the protective device and ensures the safety isolation of the processing area at all times, improving operational safety while achieving a convenient operating experience.
