[0002] The return wheel, a core component in mechanical systems for precise resetting and positioning, integrates gear transmission, elastic reset, and intelligent control technologies. It is widely used in photovoltaic equipment, industrial robots, and AGV logistics systems. Its core function is to automatically return moving parts to their correct positions through mechanical or electromechanical linkage, ensuring stable operation of equipment under complex conditions. In silicon wafer cutting and module positioning, the return wheel works in conjunction with a synchronous belt to achieve precise resetting at high speeds with extremely high transmission efficiency, improving silicon wafer utilization. To reduce friction during use, the return wheel requires polishing during manufacturing.

[0003] Most common return wheels are cylindrical bosses with different diameters at both ends. Existing polishing clamping fixtures usually require multiple clamping operations when clamping and polishing the two ends of the return wheel, resulting in low clamping efficiency and requiring multiple adjustments to the polishing position, which affects the polishing accuracy.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-4The polishing clamping fixture for the return wheel in this embodiment includes a frame 1. A mounting frame 2 is fixedly connected to the top of the frame 1. A lifting cylinder 3 is vertically fixedly connected to the top of the mounting frame 2. A lifting plate 4 is horizontally slidably connected to the inner side of the mounting frame 2. The piston rod of the lifting cylinder 3 is fixedly connected to the top of the lifting plate 4. An upper clamping electric cylinder 5 is vertically fixedly connected to the bottom of the lifting plate 4. An upper limit block 8 is provided on the piston rod of the upper clamping electric cylinder 5. A lifting top platform 6 is provided directly below the upper clamping electric cylinder 5. A lower clamping electric cylinder 10 is vertically fixedly connected to the inner side of the frame 1. The piston rod of the lower clamping electric cylinder 10 is fixedly connected to the bottom of the lifting top platform 6. A lower limit block 9 is provided at the top axis of the lifting top platform 6. A polishing mechanism 7 is provided on the side of the lifting top platform 6 for polishing and grinding the outer wall of the return wheel. The polishing mechanism 7 includes a motor 701, which is vertically fixedly connected to the top of the inner side of the frame 1. The rotating shaft of the motor 701 is fixed. A drive wheel 702 is connected to the motor 701. A support frame 703 is rotatably connected to the outer side of the middle of the motor shaft. A polishing wheel 706 is rotatably connected to the top of the support frame 703 facing the lifting platform 6. An upper limit block 8 is rotatably connected to the piston rod of the upper clamping electric cylinder 5. A lower limit block 9 is rotatably connected to the top of the lifting platform 6. The upper limit block 8 and the lower limit block 9 are coaxially arranged. A reversing seat 707 is detachably provided on the top of the support frame 703 away from the lifting platform 6. A reversing wheel 708 is rotatably connected to the reversing seat 707 away from the polishing wheel 706. A polishing belt 709 is meshed between the drive wheel 702, the polishing wheel 706, and the reversing wheel 708. A sliding plate 704 is provided at the bottom of the polishing wheel 706. A translation mechanism 705 is horizontally fixedly connected to the bottom of the support frame 703 facing the reversing seat 707. The moving platform of the translation mechanism 705 is fixedly connected to the bottom of the sliding plate 704.During polishing, the cylindrical boss-shaped return wheel is placed on top of the lower limit block 9. The lower limit block 9 is inserted into the limit hole at the bottom of the return wheel to limit its bottom. Then, the lifting cylinder 3 drives the lifting plate 4 and the upper clamping electric cylinder 5 to move downwards to the clamping position. At this time, the upper clamping electric cylinder 5 drives the upper limit block 8 to move downwards to be inserted into the top limit hole of the return wheel, clamping and limiting the return wheel. At this time, the translation mechanism 705 drives the sliding plate 704 and the polishing wheel 706 to move towards the return wheel, causing the polishing belt 709 on the outside of the polishing wheel 706 to move accordingly until the outer wall of the polishing belt 709 abuts against the outer wall of the larger diameter end of the return wheel. Then, the motor 701 is started, causing the drive wheel 702 to start rotating. When the drive wheel 702 rotates, it drives the polishing belt 709 to start rotating. When the polishing belt 709 rotates, it drives the polishing belt 709 to rotate. The return wheel rotates accordingly, polishing the outer wall of the larger diameter end of the return wheel. After the outer wall of the larger diameter end of the return wheel is polished, the upper clamping electric cylinder 5 and the lower clamping electric cylinder 10 drive the return wheel to move vertically until the outer wall of the smaller diameter end of the return wheel is at the same height as the polishing belt 709. At this time, the translation mechanism 705 drives the sliding plate 704 and the polishing wheel 706 to move towards the return wheel, causing the polishing belt 709 on the outside of the polishing wheel 706 to move until the outer wall of the polishing belt 709 abuts against the outer wall of the smaller diameter end of the return wheel. Then the above steps are repeated to polish the outer wall of the smaller diameter end of the return wheel. Through the above steps, the return wheel can be polished in all directions with a single clamping, effectively improving polishing efficiency and polishing precision.

[0022] A tensioning cylinder 710 is provided on the side wall of the polishing wheel 706. The piston rod of the tensioning cylinder 710 is rotatably connected to a tensioning wheel 711, which meshes with the inner side wall of the polishing belt 709. Before polishing, the tensioning cylinder 710 drives the tensioning wheel 711 to extend or retract, thereby tightening or loosening the polishing belt 709 outside the tensioning wheel 711, thus adjusting the tension of the polishing belt 709.

[0023] A quick-release clamp 712 is horizontally positioned on the side of the polishing wheel 706 away from the tension wheel 711. A pair of limiting wheels 713 are rotatably connected to the top and bottom of the movable end of the quick-release clamp 712. The limiting wheels 713 are slidably connected to the outer wall of the polishing belt 709. Before polishing, the quick-release clamp 712 is closed, causing the limiting wheels 712 to abut against the upper and lower edges of the polishing belt 709. When the polishing belt 709 rotates, it drives the limiting wheels 712 to rotate accordingly, thereby limiting the polishing belt 709 and preventing it from loosening during rotation.

[0024] Working principle: During polishing, the cylindrical boss-shaped return wheel is placed on top of the lower limit block 9. The lower limit block 9 is inserted into the limiting hole at the bottom of the return wheel to limit its bottom. Then, the lifting cylinder 3 drives the lifting plate 4 and the upper clamping electric cylinder 5 to move downward to the clamping position. At this time, the upper clamping electric cylinder 5 drives the upper limit block 8 to move downward to the top limiting hole of the return wheel, clamping and limiting the return wheel. At this time, the translation mechanism 705 drives the sliding plate 704 and the polishing wheel 706 to move towards the return wheel, so that the polishing wheel... The polishing belt 709 on the outer side of 706 moves until its outer wall abuts against the outer wall of the larger diameter end of the return wheel. Then, the tensioning cylinder 710 drives the tensioning wheel 711 to extend or retract, tightening or loosening the polishing belt 709 on its outer side, thus adjusting the tension of the polishing belt 709. The quick-close clamp 712 closes, causing the limiting wheels 712 to abut against the upper and lower edges of the polishing belt 709. As the polishing belt 709 rotates, the limiting wheels 712 rotate accordingly, thereby adjusting the tension of the polishing belt 709. The system is designed to limit the movement of the polishing belt 709 to prevent it from dislodging during rotation. Then, motor 701 is started, causing drive wheel 702 to rotate. The rotation of drive wheel 702 drives the polishing belt 709 to rotate, which in turn drives the return wheel to rotate, thus polishing the outer wall of the larger diameter end of the return wheel. After the outer wall of the larger diameter end of the return wheel is polished, the upper clamping electric cylinder 5 and lower clamping electric cylinder 10 drive the return wheel to move vertically until the outer wall of the smaller diameter end of the return wheel is in contact with the polishing belt 709. When the height reaches level 9, the process stops. At this point, the translation mechanism 705 drives the sliding plate 704 and polishing wheel 706 to move towards the return wheel, causing the polishing belt 709 on the outer side of the polishing wheel 706 to move accordingly until the outer wall of the polishing belt 709 abuts against the outer wall of the smaller diameter end of the return wheel. Then, the above steps are repeated to polish the outer wall of the smaller diameter end of the return wheel. Through the above steps, the return wheel can be polished in all directions with a single clamping, effectively improving polishing efficiency and polishing precision.
