[0014] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0015] 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. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0016] Example 1: As Figure 1 - Figure 6As shown, this utility model provides a technical solution: a workpiece polishing mechanism for a rotating shaft 7, including a housing 1. A first motor 2 and a second motor 4 are fixedly installed on the top operating table of the housing 1. A cylindrical rod is fixedly installed at the output end of the first motor 2. A baffle 8 and a disc 9 are fixedly installed on the cylindrical rod. A polishing wheel 3 is sleeved between the baffle 8 and the disc 9. The disc 9 is fixedly installed to the cylindrical rod by a fixing mechanism 10. A guide wheel 5 is fixedly connected to the output end of the second motor 4. A guide groove 6 is provided between the guide wheel 5 and the polishing wheel 3. The fixing mechanism 10 includes a block 1001, a fixing block 1002, and a pin 1003. A square hole 1004 is opened on the block 1001. The fixing block 1002 is fixedly installed on the side of the block 1001. The pin 1003 is inserted into the square hole 1004. The bottom end of the pin 1003 is inserted into the slot 15 opened on the cylindrical rod. The fixing block 1002 is slidably connected to the locking block 1005. The locking block 1005 is inserted into the slot 1009 opened on the pin 1003. A pull rod 1006 is fixedly installed on the other side of the locking block 1005. A pull plate 1007 is fixedly installed on the other end of the pull rod 1006. A spring 1008 is sleeved on the pull rod 1006. A magnet 12 is fixedly installed inside the slot 1009. The magnet 12 is magnetically connected to the insertion end of the locking block 1005. The end of the locking block 1005 inserted into the slot 1009 is provided with a first inclined surface 13. The bottom end of the pin 1003 is provided with a second inclined surface 14 corresponding to the position of the first inclined surface 13. The side of the pull plate 1007 that contacts the finger is provided with an anti-slip protrusion 19.

[0017] The beneficial effects achieved in this embodiment 1 are as follows: the cooperation between the disc 9 and the fixing mechanism 10 achieves the purpose of fixing the polishing wheel 3, and also facilitates the replacement of different types of polishing wheels 3 as needed. When it is necessary to replace the polishing wheel 3, simply pull the pull plate 1007 of the fixing mechanism 10. The pull plate 1007 drives the pull rod 1006 to move. The pull rod 1006 pulls the locking block 1005 out of the slot 1009 of the pin 1003 and squeezes the spring 1008. At this time, the pin 1003 can easily exit the slot 15 on the cylindrical rod and the square hole 100 in the block 1001. Pulling out from inside 4 releases the fixing restriction on the disc 9, allowing the old polishing wheel 3 to be removed and replaced with a new one. This replacement method is simple, convenient, and efficient. Compared to the method of fixing with nuts and bolts, it greatly improves the efficiency and convenience of polishing wheel 3 replacement. It can quickly switch the appropriate polishing wheel 3 according to the polishing requirements of different workpieces on different rotating shafts 7, thereby effectively improving production efficiency and ensuring the polishing quality of the workpiece and reducing downtime. A magnet 12 is fixedly installed inside the slot 1009. The magnet 12 is magnetically connected to the insertion end of the card block 1005. The magnet 12 and the card block 1005 are connected by magnetic attraction. The magnetic attraction further enhances the stability of the locking block 1005 within the slot 1009, preventing it from accidentally dislodging from the slot 1009 due to equipment vibration during normal operation of the polishing wheel 3. This ensures the reliability of the entire fixing mechanism 10 in fixing the disc 9 and the polishing wheel 3. A first inclined surface 13 is provided at the end of the locking block 1005 inserted into the slot 1009, and a second inclined surface 14 is provided at the bottom end of the pin 1003 corresponding to the first inclined surface 13. When the pin 1003 is inserted into the square hole 1004 of the block 1001 and its bottom end aligns with the first inclined surface 14, a second inclined surface 14 is provided. When the pin 1003 is inserted into the slot 1009, the second inclined surface 14 of the pin 1003 contacts the first inclined surface 13 of the block 1005. Through the guiding effect of the inclined surface, only a slight external force is applied to push the pin 1003, which will cause the block 1005 to slide automatically into the fixing block 1002. This makes it convenient and quick to insert the pin 1003 into the slot 1009, improving the ease of installation and fixing of the fixing mechanism 10. The side of the pull plate 1007 that contacts the fingers is provided with anti-slip protrusions 19, which makes it less likely for the operator to slip when pulling the pull plate 1007, making the operation more stable and reliable.

[0018] Example 2: As Figure 4 - Figure 5 As shown, a number of limiting rods 18 are fixedly installed on the side of the disc 9 facing the polishing wheel 3. A limiting groove 11 is opened on the side of the polishing wheel 3. The limiting rods 18 are inserted into the corresponding limiting grooves 11. A guide groove 16 is opened on the outer wall of one end of the cylindrical rod. A guide block 17 is fixedly installed on the inner circular surface of the disc 9. The guide block 17 is locked inside the guide groove 16.

[0019] The beneficial effects achieved in this embodiment 2 are as follows: by inserting the limiting rod 18 on the disc 9 into the limiting groove 11 on the side of the polishing wheel 3, the polishing wheel 3 can be prevented from rotating when the cylindrical rod rotates, so as not to affect the polishing effect and efficiency; by cooperating with the guide block 17 and the guide groove 16, when the disc 9 is fitted on the cylindrical rod, the guide block 17 on the inner circular surface of the disc 9 is stuck inside the guide groove 16, which plays a guiding and positioning role for the movement of the disc 9, preventing the disc 9 from rotating, and quickly realizing the alignment of the slot 15 on the cylindrical rod with the square hole 1004 on the block 1001, further improving the convenience of inserting the bottom end of the pin 1003 into the slot 15.

[0020] The working principle of this embodiment is as follows: When using the workpiece polishing mechanism of the rotating shaft 7, the workpiece to be polished is first placed in the guide groove 6. Then, the first motor 2 and the second motor 4 are started. The first motor 2 and the second motor 4 drive the polishing wheel 3 and the guide wheel 5 to rotate and polish the rotating shaft 7 that has moved between them. (How the polishing wheel 3 cooperates with the guide wheel 5 to polish the rotating shaft 7 is existing technology and will not be explained in detail here.) When the polishing wheel 3 needs to be replaced, the operator pulls the moving part of the fixing mechanism 10. Pull plate 1007 drives pull rod 1006, which in turn pulls latch 1005 to slide within fixed block 1002, compressing spring 1008 and disengaging it from slot 1009 of pin 1003. This releases latch 1005 from pin 1003. Pin 1003 is then pulled out from square hole 1004 on block 1001, and its bottom end disengages from slot 15 on cylindrical rod. Next, disc 9 is removed from cylindrical rod, and the old polishing wheel is then... 3. Remove the polishing wheel 3 and then install the new polishing wheel 3 in the reverse order. First, place the disc 9 on the side of the new polishing wheel 3 and insert the limiting rod 18 into the limiting groove 11 on the polishing wheel 3. Then, simultaneously place the polishing wheel 3 and the disc 9 onto the cylindrical rod and insert the guide block 17 on the inner circular surface of the disc 9 into the guide groove 16 on the cylindrical rod. When the square hole 1004 on the block 1001 is aligned with the slot 15, insert the pin 1003 into the square hole 1004 and press the pin 1003. The second inclined surface 14 presses against the first inclined surface 13 on the locking block 1005, causing the locking block 1005 to retract toward the interior of the fixing block 1002 and compress the spring 1008. When the bottom end of the pin 1003 is inserted into the slot 15 on the cylindrical rod, the locking block 1005 is pushed by the elastic force of the spring 1008 to insert one end of the block into the slot 1009 on the pin 1003 and magnetically attracted to the magnet 12 in the slot 1009, thereby fixing the polishing wheel 3. After that, the polishing work can continue.

[0021] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
