[0022] The present invention provides the following technical solutions:

[0023] As shown in Appendix Figures 1 to 5 , the present invention discloses a small workpiece automatic polishing machine, which includes a workbench 1, a frame 2 and a polishing mechanism 3. The frame 2 is arranged on the workbench 1, the polishing mechanism 3 is arranged on one side of the workbench 1, a feeding mechanism 4 is arranged on the frame 2, a feeding mechanism 5 is arranged on the workbench 1, a workpiece guiding tube 6 is arranged between the feeding mechanism 5 and the feeding mechanism 4, both ends of the workpiece guiding tube 6 are correspondingly connected to the feeding mechanism 5 and the feeding mechanism 4, the feeding mechanism 4 includes a first feeding mechanism 7 and a second feeding mechanism 8, a workpiece (not shown in the figure) is arranged on the feeding mechanism 5, the workpiece enters the first feeding mechanism 7 through the workpiece guiding tube 6, the first feeding mechanism 7 drives the workpiece into the second feeding mechanism 8, and the second feeding mechanism 8 sends the workpiece to the polishing mechanism 3 for polishing.

[0024] Further, the first feeding mechanism 7 includes a first feeding cylinder 9 and a first feeding push rod 10. The first feeding cylinder 9 is fixed on the frame 2. One end of the first feeding push rod 10 is connected to the first feeding cylinder 9. A workpiece clamping groove 11 is formed at the end of the first feeding push rod 10 away from the first feeding cylinder 9. The workpiece clamping groove 11 communicates with the workpiece guiding tube 6. The first feeding cylinder 9 drives the first feeding push rod 10 to reciprocate on the frame 2. Specifically, by providing the workpiece clamping groove 11 on the first feeding push rod 10, the workpieces fed by the feeding mechanism 5 to the feeding mechanism 4 can be fixed. The workpieces are conveyed to the first feeding mechanism 7 by the feeding mechanism 5, and the horizontal position of the workpieces is fixed by the workpiece clamping groove 11, preventing the workpieces from shifting or falling during the process of being conveyed from the first feeding mechanism 7 to the second feeding mechanism 8.

[0025] Further, the second feeding mechanism 8 includes a second feeding cylinder 12, a second feeding push rod 13 and a polishing die 14. The second feeding cylinder 12 is fixed on the frame 2. One end of the second feeding push rod 13 is connected to the second feeding cylinder 12. The polishing die 14 is arranged on the frame 2. A workpiece limiting hole 15 is provided on the polishing die 14. The workpiece limiting hole 15 has a first opening 16 facing the second feeding push rod 13 and a second opening 17 facing the polishing mechanism 3. The bottom surface of the second feeding push rod 13 is flush with the bottom of the first opening. Specifically, the setting of the polishing die 14 of the second feeding mechanism 8 can limit the position of the workpiece on the path leading to the polishing mechanism 3, so that the moving path of the workpiece is limited within the workpiece limiting hole 15 of the polishing die 14, and thus the workpiece will not shift, and the workpiece can accurately extend from the second opening 17 to the polishing mechanism 3.

[0026] Further, a blanking mechanism 18 is arranged on one side of the frame 2. The blanking mechanism 18 includes a fixing frame 19 and a blanking cylinder 20 arranged on the fixing frame 19. A blanking push rod 21 is arranged at one end of the blanking cylinder 20. A blanking through hole 22 is formed on the polishing die 14 near the blanking push rod 21. The blanking through hole 22 communicates with the workpiece limiting hole 15. The blanking cylinder 20 drives the blanking push rod 21 to extend into and out of the blanking through hole 22. In this design, the workpieces are conveyed to one end close to the second feeding mechanism 8 by the first feeding mechanism, and the workpieces on the first feeding mechanism 7 are pushed onto the second feeding mechanism 8 by the blanking mechanism 18. In this design, the blanking push rod 21 pushes the workpieces to the position where the blanking through hole 22 intersects with the workpiece limiting hole 15 under the drive of the blanking cylinder 20, and then the second feeding mechanism 8 pushes the workpieces out from the second opening 17, so that the workpieces can be polished by the polishing mechanism 3.

[0027] Further, a through hole corresponding to the second opening 17 is formed on one side of the frame 2 close to the polishing die 14. The through hole corresponds to the polishing mechanism 3. The polishing mechanism 3 includes a polishing assembly 23 and a polishing oil cylinder 24. A transmission shaft is arranged between the polishing oil cylinders 24. The polishing oil cylinder 24 drives the polishing assembly 23 to rotate through the transmission shaft.

[0028] Specifically, the polishing assembly 23 includes a polishing sand belt 29 and a polishing roller. The polishing roller includes a first polishing roller 25 and a second polishing roller 26. A connecting frame 27 is arranged between the first polishing roller 25 and the second polishing roller 26. The first polishing roller 25 and the second polishing roller 26 are connected through the connecting frame 27. One end of the first polishing roller 25 is connected to the polishing oil cylinder 24 through a transmission shaft. The polishing sand belt 29 is wound around the first polishing roller 25 and the second polishing roller 26.

[0029] Further, the feeding mechanism 5 is a vibrating disk (not shown in the figure). Workpieces are arranged inside the vibrating disk. One end of the vibrating disk is connected to a workpiece guiding tube 6. The height of the vibrating disk is higher than that of the feeding mechanism 4. The workpiece guiding tube 6 includes a tube body and a tube body guard plate. The cross section of the tube body is arranged in a C-shaped structure. An opening is formed on one side of the tube body. The tube body guard plate is arranged on one side inside the tube body close to the opening. Specifically, by arranging the feeding mechanism 5 and connecting the feeding mechanism 5 to the feeding mechanism 4, it is convenient for the workpieces to automatically enter the workpiece guiding tube 6 under the action of the vibrating disk. Since the workpiece guiding tube 6 is arranged in a structure having a first smooth portion 28, a second smooth portion 30 and a connecting portion 31, the workpieces in the vibrating disk can quickly enter the feeding mechanism 4 through the workpiece guiding tube 6 for processing.

[0030] Specifically, a recycling box (not shown in the figure) is further arranged on one side of the workbench 1. The recycling box is arranged below one side of the second feeding mechanism 8. The recycling box 8 recycles the debris generated by the polishing die 14.

[0031] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to those skilled in the art. The general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but rather to the widest scope consistent with the principles and novel features disclosed herein.
