Technical Field
[0001] The utility model relates to the technical field of polishing quick-change heads, in particular to a polishing quick-change head which is convenient to assemble and disassemble. Background Art
[0002] With the further optimization and development of mechatronics, it is common to see robots flexibly braking and operating various actions that were once only possible manually. Now, through programming, they can perform precise mechanized operations. For example, on the polishing and grinding production line, the end of the robot is connected to the fixture of the polishing and grinding head, controlling the position, direction, angle, and accuracy of the polishing head on the workpiece. The polishing quick-change head is an accessory for polishing machines that allows users to quickly change polishing heads to switch between different polishing tasks. This design can significantly improve work efficiency and reduce the time required to change polishing heads.
[0003] The existing quick-change polishing heads need to be replaced according to different processing requirements. Once the grinding position, direction, angle of the grinding head or the workpiece being polished changes, it is necessary to replace the entire grinding machine connected to the robot and the grinding head fixture matching different specifications to achieve the purpose of replacing the grinding head. The polishing head needs to be replaced frequently, but the replacement process is relatively cumbersome, resulting in low work efficiency. Utility Model Content

[0007] Through this technical solution, the fixed block provides the basic support structure for the entire polishing quick-change head. It contacts the bottom of the quick-change head body and serves as the foundation for the installation and interaction of other parts, ensuring the stability of the entire structure. The mounting slots on the top facilitate the installation and connection with other components. The four mounting slots design ensures a more stable and balanced connection.
[0008] As a further improvement of the above solution, the inner wall of the protective ring is fixedly connected to the surface of the fixed block, the surface of the locking bolt is connected to the internal thread of the fixed block through the protective ring, and the left end of the clamping block is fixedly connected to the right end of the locking bolt.
[0009] Through this technical solution, the inner wall of the protective ring is fixedly connected to the surface of the fixed block, protecting the internal structure of the fixed block and preventing external factors from interfering with and damaging the internal structure, such as the locking bolt. It also provides a stable working environment for the locking bolt, ensuring its normal threaded connection operation. The left end of the clamping block is fixedly connected to the right end of the locking bolt, which then engages with the inner wall of the notch on the bearing surface. This, in conjunction with the locking bolt, secures the bearing and prevents it from loosening during operation. This is a key structure for achieving stable operation and convenient assembly and disassembly of the quick-change head.
[0010] As a further improvement of the above solution, a notch is provided on the bearing surface, and the right end of the clamping block is clamped with the inner wall of the notch.
[0011] Through the above technical solution, the bearing plays a key transmission connection role inside the quick-change head body, and the top is connected to the top of the quick-change head body, making the rotation smoother during the polishing process, reducing the loss of equipment due to friction, and improving work efficiency. A limit rod is set inside and a slot is opened on the surface. These structures cooperate with other parts to realize the function of easy disassembly and assembly of the quick-change head.
[0012] As a further improvement of the above solution, the rear end of the sealing member is fixedly connected to the front end of the protective ring, and the front end of the sealing member is in contact with the rear end of the locking bolt.
[0013] Through the above technical solution, the front end of the seal contacts the rear end of the locking bolt, and the rear end is fixedly connected to the front end of the protective ring, which plays a sealing role, preventing external dust, moisture and other impurities from entering the interior of the fixed block, protecting the internal structure, especially the threaded connection part between the locking bolt and the fixed block, and extending the service life of the equipment.
[0014] Compared with the prior art, the beneficial effects of the present invention are:
[0015] The utility model realizes connection and disassembly with other components by means of a locking bolt provided at the front end of a fixing block through a quick-change head. When disassembly is required, the locking bolt is turned. Due to the clamping relationship between the clamping block and the clamping groove (10) on the bearing surface, as the locking bolt is turned, the clamping block is disengaged from the clamping groove, and the quick-change head body can be conveniently removed from the fixing block. The same is true for installation. The operation is simple and fast, which improves work efficiency.
[0016] A bearing is installed inside the quick-change head body, and the bearing is connected to the fixed block through a limit rod and a limit slot. This structure can ensure the stability of the quick-change head during operation. At the same time, a protective ring is installed on the surface of the fixed block. The protective ring not only protects the internal locking bolts and other components from external influences, but also enhances the stability of the overall structure.
[0017] The utility model provides a seal to ensure the tightness between the locking bolt and the protective ring. When working in an environment where dust, liquid, etc. may be present, it can prevent foreign matter from entering the interior of the fixed block, thereby protecting the internal components and extending the service life of the equipment.
[0018] There are two connecting holes on the connecting ring at the top of the quick-change head body. This structure is convenient for connecting with other equipment or components through connecting parts such as bolts. The connection is firm and easy to operate. BRIEF DESCRIPTION OF THE DRAWINGS

[0032] The implementation principle of a polishing quick-change head that is easy to disassemble and assemble in the embodiment of the present application is as follows: when an external power source acts on the quick-change head, the power is transmitted to the quick-change head body 2 through the connecting ring 13. Since a bearing 3 is provided inside the quick-change head body 2, the bearing 3 plays a role of support and friction reduction, so that the quick-change head body 2 can rotate smoothly relative to the fixed block 1. The limit rod 6 inside the bearing 3 plays a role of further stabilizing the rotation of the bearing 3 to prevent it from axial displacement during operation. During installation, the quick-change head body 2 is placed in the installation groove 7 at the top of the fixed block 1, so that the limit groove 5 of the bearing 3 is engaged with the limit groove 5 at the top of the fixed block 1, and then the locking bolt 8 is screwed into the inside of the fixed block 1 from the protective ring 11, so that the clamping block 9 is engaged with the clamping groove 10 on the surface of the bearing 3, thereby firmly fixing the quick-change head body 2 on the fixed block 1. The seal 12 plays a role of sealing protection in this process, preventing foreign matter from entering the interior through the gap between the locking bolt 8 and the protective ring 11. When disassembly is required, the locking bolt 8 can be unscrewed according to the reverse operation.
