[0031] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0032] Reference Figure 1-Figure 3The utility model provides an embodiment: a high-efficiency diamond grinding tool with a quick-change grinding disc structure, including a shell 1, an electric slide rail 2 is fixedly connected to the top of the shell 1, a fixed platform 3 is arranged inside the electric slide rail 2, a connecting shaft 6 is rotatably connected inside the fixed platform 3, a worm wheel 7 is fixedly connected to the outer wall of the connecting shaft 6, a connecting plate 10 is fixedly connected to the outer wall of the connecting shaft 6, a worm 4 is rotatably connected inside the fixed platform 3, a hand wheel 5 is fixedly connected to one end of the worm 4, the worm wheel 7 is meshed with the outer wall of the worm 4, a limited block 13 is slidably connected inside the fixed platform 3, and a latch 14 is fixedly connected to the bottom of the limited block 13, A pull rod 12 is fixedly connected to one side of the limit block 13, and a connecting rod 11 is rotatably connected to one end of the pull rod 12. One end of the connecting rod 11 is rotatably connected to the inside of the connecting plate 10. A reset assembly is arranged inside the fixed platform 3, and a connecting block 9 is slidably connected to the inside of the fixed platform 3. A grinding disc 8 is fixedly connected to the bottom of the connecting block 9. The outer wall of the latch 14 is slidably connected to the inside of the connecting block 9. The reset assembly includes a telescopic rod 15, and a spring 16 is sleeved on the outer wall of the telescopic rod 15. One end of the telescopic rod 15 and the spring 16 are fixedly connected to the inside of the fixed platform 3, and the other end of the telescopic rod 15 and the spring 16 are fixedly connected to the other side of the limit block 13;
[0033] Specifically, in actual operation, when the grinding disc 8 needs to be disassembled and replaced, the operator only needs to gently turn the hand wheel 5. This simple action starts the entire disassembly mechanism. The rotation of the hand wheel 5 drives the rotation of the worm 4, which drives the rotation of the worm wheel 7. The rotation of the worm wheel 7 is transmitted to the connecting disk 10 through the connecting shaft 6. The connecting disk 10 is a key connecting component. Its rotation transmits force to the connecting rod 11. The connecting rod 11 is closely connected with the pull rod 12. As the connecting disk 10 rotates, the pull rod 12 also starts its movement trajectory. The movement of the pull rod 12 eventually leads to the retraction of the pin 14. The pin 14 was originally fixed in the fixed platform 3 to fix the grinding disc 8, but under the push of the pull rod 12, the pin 14 gradually retracts into the fixed platform 3, thereby separating from the connecting block 9. This process The process is easy and quick, without the use of any additional tools or equipment. When the pin 14 is completely separated from the connecting block 9, the grinding disc 8 can be easily removed. At this time, the operator only needs to place the new grinding disc 8 at a suitable position on the fixed table 3 and insert it through the connecting block 9. Next, the installation process is reversed. The operator turns the hand wheel 5 again, but this time it is reverse rotation. The rotation of the hand wheel 5 again drives the operation of the entire transmission system. The connecting disc 10 drives the reset of the pull rod 12 through the connecting rod 11. With the reset of the pull rod 12, the pin 14 also begins to be reinserted into the connecting block 9. In the process of the pin 14 being embedded in the connecting block 9, the spring 16 plays an important auxiliary role. The tension of the spring 16 provides additional power for the insertion of the pin 14, making the installation process more labor-saving and efficient.
[0034] Reference Figure 1 , Figure 4 and Figure 5 A fixing ring 17 is fixedly connected inside the shell 1, and a limiting block 2 18 arranged in a ring array is slidably connected inside the fixing ring 17. The bottom of the fixing ring 17 is rotatably connected to a limiting plate 20, and a tooth block 23 is fixedly connected to the inner wall of the limiting plate 20. An arc groove 21 is provided inside the limiting plate 20, and a clamping plate 19 is fixedly connected to the top of the limiting block 18. The bottom of the clamping plate 19 is slidably connected to the inside of the fixing ring 17. A guide column 22 is fixedly connected to the bottom of the limiting block 18, and the outer wall of the guide column 22 is slidably connected to the inside of the arc groove 21. A motor 24 is fixedly connected inside the fixing ring 17, and a gear 25 is fixedly connected to the output end of the motor 24. A tooth block 23 is fixedly connected inside the limiting plate 20, and the tooth block 23 is meshed with the outer wall of the gear 25.
[0035] Specifically, when installing the parts to be processed, first place the parts accurately in the clamping plate 19, and the output end of the motor 24 drives the gear 25 to rotate. The gear 25 transmits the power to the limit plate 20 by meshing with the tooth block 23. Driven by the gear 25, the limit plate 20 starts to rotate. At this time, the arc groove 21 on the limit plate 20 plays a key role. This arc groove 21 is cleverly designed with a certain curvature so that when the limit plate 20 rotates, it can guide the limit block 18 at the bottom of the column 22 to move. The limit block 18 is subject to a certain limiting effect in the fixing ring 17, which enables it to convert the arc motion trajectory into a linear motion under the guidance of the arc groove 21. This conversion mechanism The system ensures the uniform distribution and stability of the clamping force, thereby improving the effect of part fixation. As the limit block 18 moves, it drives the clamp 19 to clamp and fix the part. Under the push of the limit block 18, the clamp 19 fits tightly on the surface of the part to form a strong clamping force. This clamping method is not only stable and reliable, but also can adapt to parts of different materials and shapes, thereby improving the flexibility and adaptability of the processing process. When the part is firmly clamped in the clamp 19, the next step is to perform grinding. The grinding disc 8 is installed on the fixed table 3 as a grinding tool. Through the precise control of the electric slide rail 2, the grinding disc 8 can accurately descend to the surface of the part to start grinding the part.
[0036] Working principle: When using the high-efficiency diamond grinding tool with a quick-change grinding disc structure, first install the part to be processed, place the part in the clamping plate 19, then the output end of the motor 24 drives the gear 25 to rotate, the gear 25 drives the limit plate 20 to rotate through the tooth block 23, and the limit plate 20 drives the limit block 18 at the bottom of the guide column 22 to move through the arc groove 21. Since the limit block 18 is limited in the fixing ring 17, the limit block 18 converts the arc of the arc groove 21 into a linear motion, and then the limit block 18 drives the clamping plate 19 to clamp and fix the part, and then the grinding disc 8 is installed on the fixed table 3 and lowered by the electric slide rail 2 to grind the part. When the grinding disc 8 needs to be adjusted When disassembling and replacing, it is only necessary to drive the worm 4 to rotate through the handwheel 5, and the worm 4 drives the connecting shaft 6 to rotate through the worm gear 7, and the connecting shaft 6 drives the connecting disk 10 to rotate, and then the connecting rod 11 drives the pull rod 12 through the connecting disk 10 to retract the pin 14 into the fixed platform 3, and then the pin 14 is separated from the connecting block 9 to remove the grinding disc 8, and then the new grinding disc 8 is inserted into the fixed platform 3 through the connecting block 9, and then the handwheel 5 is rotated in the opposite direction, so that the connecting disc 10 drives the pull rod 12 to reset through the connecting rod 11, and the pull rod 12 drives the pin 14 to insert into the connecting block 9 to lock it. In the process of the pin 14 being embedded in the connecting block 9, the tension of the spring 16 will assist in pushing, saving effort during the installation process.
