[0019] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0020] Please see Figure 1 - Figure 5This utility model provides an embodiment of a quick-connect structure for the grinding wheel of a grinding machine, including a main shaft 1 and a grinding disc 2. An annular surrounding plate 3 is provided at the upper end of the grinding disc 2. An end cap 4 connecting the grinding wheel 21 is provided at the lower end of the main shaft 1. A slot 5 is formed through the end cap 4. A locking block 6 adapted to the slot 5 is provided at the upper end of the grinding wheel 21. A locking hole 7 is provided on the side end of the locking block 6. A locking groove 8 is provided at the upper end of the end cap 4. A first locking mechanism adapted to the locking hole 7 is provided in the locking groove 8. A through groove 9 is provided on the side wall of the grinding wheel 21. A limiting groove 10 is provided on the inner wall of the through groove 9. A second locking mechanism adapted to the limiting groove 10 is provided on the side wall of the end cap 4. The main shaft 1 bears the rotational power of the entire grinding system. The lower end of the main shaft 1 is connected to an end cap 4. The end cap 4 not only serves to fix the grinding wheel 21 but also acts as the quick-connect structure for the entire grinding machine. As a key component of the structure, the grinding disc 2 is located above the spindle 1 and is the direct working surface for grinding operations. An annular enclosure 3 is set at its upper end. The function of the enclosure 3 is to prevent the spatter generated during the grinding process from scattering everywhere, keeping the working environment clean and safe. The shape of the slot 5 perfectly matches the locking block 6 at the upper end of the grinding wheel 21, ensuring the stable installation of the grinding wheel 21 on the spindle 1. The locking block 6 has a locking hole 7, which is used to cooperate with the first locking mechanism on the end cover 4 to further lock the grinding wheel 21 and prevent it from loosening or falling off during high-speed rotation. A through groove 9 is opened on the side wall of the grinding wheel 21. A limiting groove 10 is designed on the inner wall of the through groove 9. This limiting groove 10 cooperates with the second locking mechanism on the end cover 4 to further enhance the stability of the grinding wheel 21 on the spindle 1.

[0021] Please see Figure 1 and Figure 4 In this embodiment, the first locking mechanism includes a support plate 11, which is fixedly connected to the locking groove 8. A screw hole is formed through the support plate 11, and a locking screw 12 is threaded into the screw hole. A knob 13 is provided at one end of the locking screw 12, and a tapered head 20 is provided at the end of the locking screw 12 away from the knob 13. The diameter of the tapered head 20 gradually decreases from the locking screw 12 away from it. The support plate 11 serves as the basic support structure of the first locking mechanism, and a screw hole is formed through the support plate 11 for the locking screw. The channel connecting the grinding wheel 21 to the support plate 11 is provided. The locking screw 12 is responsible for connecting the locking hole 7 on the grinding wheel 21 to the support plate 11, thereby locking the grinding wheel 21. One end of the locking screw 12 is designed with a first knob 13, which is the tool for the operator to lock and unlock. The other end of the locking screw 12 is provided with a conical head 20. This design allows the conical head 20 to be more easily inserted into the locking hole 7 of the grinding wheel 21 and gradually squeeze the hole wall during rotation to form a tight locking effect, thereby improving the stability of the lock.

[0022] Please see Figure 1 and Figure 5 In this embodiment, the second locking mechanism includes a fixing plate 14. The side wall of the end cap 4 is provided with a fixing plate 14. A fixing shaft 15 is provided between two adjacent fixing plates 14. A rotating plate 16 is rotatably connected to the outer wall of the fixing shaft 15. A limiting screw 17 is internally threaded onto the rotating plate 16. A second knob 18 is provided at the upper end of the limiting screw 17. A limiting plate 19, adapted to the limiting groove 10, is fixedly connected to the lower end of the limiting screw 17. The limiting plate 19 rotates and engages in the limiting groove 10. Adaptive magnets are provided in both the limiting plate 19 and the limiting groove 10. The limiting plate 19 and the limiting groove 10 are magnetically connected. Rubber sheets are provided on the outer walls of the first knob 13 and the second knob 18. The surface of the rubber sheets has anti-slip textures. The fixing plate 14 is the basic support component of the second locking mechanism. The fixing shaft 15 provides a fulcrum for the rotation of the rotating plate 16. The rotating plate 16 is connected to the fixing plate 14 through the fixing shaft 15 and can... The rotating plate 16 is used to connect with the limiting screw 17 by thread. The limiting screw 17 is used to rotate the limiting plate 19, thereby locking the grinding wheel 21. The upper end of the limiting screw 17 is provided with a second knob 18, which is the tool for the operator to perform rotation. When the limiting screw 17 rotates, the limiting plate 19 will move accordingly and eventually be locked into the limiting groove 10, thereby locking the grinding wheel 21. The magnet can generate a strong magnetic force to firmly attract the limiting plate 19 into the limiting groove 10. The outer walls of the first knob 13 and the second knob 18 are provided with rubber skin. The rubber skin has good anti-slip and wear resistance, which can increase the operator's grip comfort and stability. At the same time, the surface of the rubber skin is also provided with anti-slip texture. These anti-slip textures can further increase the friction between the operator's fingers and the knob, preventing slippage during rotation.

[0023] During the operation, firstly, the locking block 6 on the grinding wheel 21 is accurately embedded into the slot 5 of the end cover 4. Then, by rotating the first knob 13, the locking screw 12 is driven to move forward until its conical head 20 is firmly locked into the locking hole 7 of the grinding wheel 21, thus achieving initial locking.

[0024] Next, the rotating plate 16 is operated to make the limiting plate 19 align with and enter the through groove 9 of the grinding wheel 21. Then, the second knob 18 is rotated. This action causes the limiting screw 17 to rotate, which in turn pushes the limiting plate 19 to rotate and tightly lock into the limiting groove 10. During this process, the magnets built into the limiting plate 19 and the limiting groove 10 attract each other, further enhancing the stability of the lock.

[0025] Through the above steps, this solution improves the speed of installation of the grinding wheel 21 on the spindle 1 by using the first locking mechanism and the second locking mechanism in combination, thereby simplifying the installation process. The conical head 20 design of the first locking mechanism makes the locking tighter and more secure, while the second locking mechanism uses the magnetic effect of the magnet and the snap-fit ​​structure of the limiting plate 19 to further enhance the locking effect of the grinding wheel 21, thereby ensuring the high efficiency, safety and stability of the grinding operation, and solving the problems of the traditional grinding wheel 21 installation method being cumbersome, time-consuming and affecting the efficiency of the grinding operation.

[0026] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
