Description

Technical Field

[0001] This utility model relates to the field of polishing disc technology, specifically a detachable polishing disc for a polishing machine. Background Technology

[0002] The polishing disc and polishing machine can be disassembled and replaced. In the existing technology, the polishing disc is generally connected by a threaded rod to the threaded tube on the polishing disc, and then the polygonal column is locked to the rotating output end of the polishing machine. This completes the installation and is easy to disassemble. However, in actual use, due to the high speed of the polishing disc, the polishing disc is connected to the threaded tube through the threaded rod. This structural design makes the locking between the threaded rod and the threaded tube increasingly tight during the rotation of the polishing disc, which is inconvenient for later separation and is relatively difficult to disassemble. Utility Model Content

[0003] Therefore, the purpose of this utility model is to provide a detachable polishing disc for a polishing machine. Through the cooperation of the polishing disc assembly and the positioning assembly, the threaded rod is repositioned after locking during use. The positioning point is subjected to force, which avoids the problem of the threaded connection becoming increasingly tight and difficult to disassemble during the rotation of the polishing disc, and facilitates subsequent replacement.

[0004] To solve the above-mentioned technical problems, according to one aspect of the present invention, the present invention provides the following technical solution: a detachable polishing disc for a polishing machine, comprising:

[0023] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0024] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0025] Secondly, this utility model is described in detail with reference to the schematic diagrams. When describing the embodiments of this utility model, for ease of explanation, the cross-sectional views illustrating the device structure may be partially enlarged, not adhering to the usual scale. Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of this utility model.

[0026] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0027] This utility model provides a detachable polishing disc for a polishing machine. Through the cooperation of the polishing disc assembly and the positioning assembly, the threaded rod is repositioned after locking during use. The positioning point is subjected to force, which avoids the problem of the threaded connection becoming increasingly tight and difficult to disassemble during the rotation of the polishing disc, and facilitates subsequent replacement.

[0028] Figures 1-4 The diagram shown is an overall structural schematic of an embodiment of the detachable polishing disc for a polishing machine according to this utility model. Please refer to [link / reference]. Figures 1-4 The main structure of this embodiment includes: a polishing disc assembly and a positioning assembly.

[0029] The polishing disc assembly is used for rotary polishing. Specifically, the polishing disc assembly includes a polishing disc 11, a cylinder 12 fixed on the top surface of the polishing disc 11, a threaded tube 13 embedded in the cylinder 12, a threaded rod 14 set above the polishing disc 11, a hexagonal disc 15 fixed on the top surface of the threaded rod 14, and a polygonal column 16 fixed on the top surface of the hexagonal disc 15.

[0030] In practical use, the threaded rod 14 is connected to the threaded tube 13, and the polygonal column 16 is locked to the output end of the external polishing machine, so that the polishing machine can drive the polishing disc 11 to rotate for polishing.

[0031] The positioning component is used for positioning the threaded connection. Specifically, the positioning component includes a notch 21 on the frame of the hexagonal disk 15, a round shaft 22 in the notch 21, a sleeve 23 fitted with the round shaft 22, an L-shaped hook 24 fixed on the sleeve 23, an arc-shaped threaded plate 26 fixed on the back of the L-shaped hook 24, and a hole 25 on the cylinder 12.

[0032] In practical use, the user pulls the L-shaped hook 24 downwards, and the sleeve 23 drives the L-shaped hook 24 to rotate along the circular shaft 22. The end of the L-shaped hook 24 engages with the hole 25. Then, the threaded ring is connected to the distributed arc-shaped threaded plates 26, which gathers the distributed L-shaped hooks 24 together. At this time, positioning can be achieved. During the rotation of the polishing disc 11, the L-shaped hook 24 is under force. At this time, the threaded rod 14 and the threaded tube 13 will not get closer and closer, which is convenient for replacement. At the same time, the double locking structure also prevents the cylinder 12 from accidentally separating from the threaded rod 14.

[0033] Furthermore, it also includes a locking assembly, which includes a threaded cylinder 31 fixed to the bottom surface of the hexagonal disk 15 and an external thread 32 formed on the outer wall of the cylinder 12.

[0034] In practical use, the threaded cylinder 31 is located outside the threaded rod 14 and is connected to the external thread 32. In this way, during the connection between the threaded rod 14 and the threaded tube 13, the outer cylinder 12 is also locked by the threaded cylinder 31. This can prevent the entire polishing disc 11 from falling off due to the falling off of the threaded tube 13, and improve the stability of the polishing disc 11 in use.

[0035] Although the present invention has been described above with reference to embodiments, various modifications can be made and components can be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the features in the embodiments disclosed in this invention can be combined with each other in any way. The lack of an exhaustive description of these combinations in this specification is merely for the sake of brevity and resource conservation. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
