[0002] Fountain pens, as a common type of pen, have a long history. Early fountain pens were mostly made of metal. As development progressed, fountain pen materials became more diverse. However, due to the decline in usage, most fountain pens are now used as signing pens or souvenirs, so they have returned to metal materials. They are generally exquisite in appearance, so the shell is finely processed during the production process, among which polishing is an essential step.

[0003] However, the surface polishing equipment currently used for pen casing processing still has some defects in use. It cannot quickly fix the pen casing before polishing, which makes the casing prone to shaking or displacement during the polishing process, affecting the polishing effect.

[0004] A novel, easy-to-fix pen casing surface polishing device is proposed to solve the above-mentioned problems. Summary of the Invention

[0007] The fixing structure includes a mounting plate. A set of mounting plates is movably connected to the top and bottom of one end of the fixing box. A bidirectional lead screw is movably connected inside the fixing box. A set of threaded sleeves is movably connected to both ends of the bidirectional lead screw. A connecting block is fixedly connected to one end of the threaded sleeve. A sliding groove is opened at one end of the fixing box. A second servo motor is fixedly connected to the bottom end of the fixing box. A fixing sleeve is movably connected to one side of one end of the mounting plate.

[0008] As a further technical solution of this utility model, the connecting block is fixedly connected to the mounting plate through the sliding groove, and the mounting plate is slidably connected to the fixed box.

[0009] As a further technical solution of this utility model, the output end of the second servo motor passes through the bottom end of the fixed box and is fixedly connected to the bidirectional lead screw, and the threaded sleeves at both ends of the bidirectional lead screw are arranged symmetrically.

[0010] As a further technical solution of this utility model, a fixed cover is fixedly connected to one end of the mounting plate, and a transmission sprocket is movably connected to both sides inside the fixed cover. A chain is movably connected to the outside of the transmission sprocket. A square telescopic rod is fixedly connected to one side of the other end of the mounting plate, and a second drive motor is fixedly connected to one side of one end of the fixed cover.

[0011] As a further technical solution of this utility model, the transmission sprocket is fixedly connected to the mounting plate and the fixed sleeve, the output end of the second drive motor extends into the interior of the fixed cover and is fixedly connected to the transmission sprocket, and the square telescopic rod is fixedly connected to the mounting plate and the transmission sprocket.

[0013] As a further technical solution of this utility model, the reciprocating lead screw is threadedly connected to the threaded hole, the support shaft is slidably connected to the through hole, and the output end of the first servo motor passes through one end of the movable frame and is fixedly connected to the reciprocating lead screw.

[0014] As a further technical solution of this utility model, the output end of the electric cylinder is fixedly connected to the movable frame, the movable frame is slidably connected to the limiting plate, and the output end of the first drive motor extends into the interior of the movable frame and is fixedly connected to the polishing wheel.

[0015] Compared with the prior art, the beneficial effects of this utility model are: the easy-to-fix pen shell surface polishing device not only achieves quick fixation and automatic drive of the shell, but also achieves automatic drive of the polishing wheel to move for complete polishing;

[0016] The system is equipped with a fixed box, mounting plate, slide rail, second servo motor, fixed sleeve, threaded sleeve, bidirectional lead screw, and connecting block. Before polishing, the pen shell to be polished is placed between two sets of fixed sleeves. Then, the second servo motor is started to drive the bidirectional lead screw to rotate. The bidirectional lead screw drives the connecting block to move through the threaded sleeve. Finally, the connecting block drives the mounting plates at both ends to move.

[0017] By setting up a fixed box, a fixed cover, a second drive motor, a mounting plate, a square telescopic rod, a transmission sprocket, a chain, and a fixed sleeve, after the pen shell is fixed, the second drive motor can be started to drive a set of transmission sprockets inside the fixed cover to rotate, and the chain drives two sets of transmission sprockets to rotate synchronously. Then, the square telescopic rod drives the transmission sprockets at both ends to rotate synchronously. Finally, the transmission sprockets drive the fixed sleeve to rotate, thereby driving the pen shell inside to rotate for rapid polishing.

[0018] By incorporating a movable frame, a first servo motor, a first drive motor, a reciprocating lead screw, a support shaft, a limit plate, an electric cylinder, a moving frame, a polishing wheel, threaded holes, and through holes, the polishing process involves first activating the electric cylinder to move the movable frame to one side. The movable frame then moves the polishing wheel via the moving frame, bringing it into contact with the outside of the pen casing. Next, the first drive motor rotates the polishing wheel to polish the outside of the pen. Finally, the first servo motor rotates the reciprocating lead screw, which in turn drives the moving frame to reciprocate through the threaded hole. The moving frame then drives the polishing wheel to reciprocate, polishing the entire pen casing. This system enables automatic movement of the polishing structure to polish the pen casing.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. 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.

[0025] Example: Please refer to Figure 1-4 A polishing device for the surface of a pen casing that is easy to fix includes a fixed platform 1, a fixed box 5 fixedly connected to one side of one end of the fixed platform 1, and a movable frame 2 movably connected to the other side of one end of the fixed platform 1. The center line of the movable frame 2 and the center line of the fixed box 5 are on the same horizontal plane. A fixing structure for fixing the pen casing is provided at one end of the fixed box 5.

[0026] The fixed structure includes a mounting plate 8. A set of mounting plates 8 are movably connected to the top and bottom of one end of the fixed box 5. A bidirectional lead screw 24 is movably connected inside the fixed box 5. A set of threaded sleeves 23 are movably connected to both ends of the bidirectional lead screw 24. A connecting block 25 is fixedly connected to one end of the threaded sleeve 23. A sliding groove 10 is opened at one end of the fixed box 5. A second servo motor 13 is fixedly connected to the bottom end of the fixed box 5. A fixed sleeve 14 is movably connected to one side of one end of the mounting plate 8.

[0027] The connecting block 25 is fixedly connected to the mounting plate 8 through the sliding groove 10, and the mounting plate 8 is slidably connected to the fixed box 5.

[0028] The output end of the second servo motor 13 passes through the bottom end of the fixed box 5 and is fixedly connected to the bidirectional lead screw 24. The threaded sleeves 23 at both ends of the bidirectional lead screw 24 are arranged symmetrically.

[0029] Specifically, such as Figure 1 , Figure 3 and Figure 4As shown, before polishing, the pen casing to be polished is placed between two sets of fixed sleeves 14. Then, the second servo motor 13 is started to drive the bidirectional lead screw 24 to rotate. The bidirectional lead screw 24 drives the connecting block 25 to move through the threaded sleeve 23. Finally, the connecting block 25 drives the mounting plates 8 at both ends to move. As the two sets of mounting plates 8 move towards the middle, the fixed sleeve 14 is fitted onto the outside of the pen casing, thereby effectively fixing the pen casing and realizing the ability to quickly fix the pen casing.

[0030] One end of the mounting plate 8 is fixedly connected to a fixed cover 6. The two sides inside the fixed cover 6 are movably connected to a transmission sprocket 11. The outside of the transmission sprocket 11 is movably connected to a chain 12. One side of the other end of the mounting plate 8 is fixedly connected to a square telescopic rod 9. One side of one end of the fixed cover 6 is fixedly connected to a second drive motor 7.

[0031] The transmission sprocket 11 passes through the mounting plate 8 and is fixedly connected to the fixed sleeve 14. The output end of the second drive motor 7 extends into the interior of the fixed cover 6 and is fixedly connected to the transmission sprocket 11. The square telescopic rod 9 passes through the mounting plate 8 and is fixedly connected to the transmission sprocket 11.

[0032] Specifically, such as Figure 1 , Figure 3 and Figure 4 As shown, after the pen casing is fixed, the second drive motor 7 can be started to drive a set of transmission sprockets 11 inside the fixed cover 6 to rotate, and the chain 12 drives the two sets of transmission sprockets 11 to rotate synchronously. Then, the square telescopic rod 9 drives the transmission sprockets 11 at both ends to rotate synchronously. Finally, the transmission sprockets 11 drive the fixed sleeve 14 to rotate, thereby driving the pen casing inside the fixed sleeve 14 to rotate for rapid polishing. This realizes that the pen casing can be automatically driven to rotate for polishing.

[0033] A set of limiting plates 17 are fixedly connected to the top and bottom of one side of the fixed platform 1. A reciprocating screw 15 is movably connected to one side of the interior of the movable frame 2. A support shaft 16 is fixedly connected to the other side of the interior of the movable frame 2. An electric cylinder 18 is fixedly connected to one side of one side of the fixed platform 1. A movable frame 19 is movably connected to the interior of the movable frame 2. A polishing wheel 20 is movably connected to one side of the interior of the movable frame 19. A first drive motor 4 is fixedly connected to one side of one end of the movable frame 19. A threaded hole 21 is opened at one end of the movable frame 19. A through hole 22 is opened on one side of one end of the movable frame 19. A first servo motor 3 is fixedly connected to one side of the top of the movable frame 2.

[0034] The reciprocating screw 15 is threadedly connected to the threaded hole 21, the support shaft 16 is slidably connected to the through hole 22, and the output end of the first servo motor 3 passes through one end of the movable frame 2 and is fixedly connected to the reciprocating screw 15.

[0035] The output end of the electric cylinder 18 is fixedly connected to the movable frame 2, the movable frame 2 is slidably connected to the limiting plate 17, and the output end of the first drive motor 4 extends into the interior of the movable frame 19 and is fixedly connected to the polishing wheel 20.

[0036] Specifically, such as Figure 1 and Figure 2 As shown, during polishing, the electric cylinder 18 is first activated to push the movable frame 2 to one side. The movable frame 2 then pushes the polishing wheel 20 to move through the moving frame 19 so that it fits against the outside of the pen casing. Next, the first drive motor 4 is activated to drive the polishing wheel 20 to rotate and polish the outside of the pen. Finally, the first servo motor 3 is activated to drive the reciprocating screw 15 to rotate. The reciprocating screw 15 drives the moving frame 19 to reciprocate through the threaded hole 21. The moving frame 19 then drives the polishing wheel 20 to reciprocate and polish the pen casing as a whole. This achieves automatic drive of the polishing structure to move and polish the pen casing.

[0037] Working Principle: In use, before polishing, the pen casing to be polished is placed between two sets of fixing sleeves 14. Then, the second servo motor 13 is started, driving the bidirectional lead screw 24 to rotate. The bidirectional lead screw 24 drives the connecting block 25 to move through the threaded sleeve 23. Finally, the connecting block 25 drives the mounting plates 8 at both ends to move. As the two sets of mounting plates 8 move towards the center, the fixing sleeves 14 are fitted onto the outside of the pen casing, effectively fixing the pen casing. After fixing the pen casing, the second drive motor 7 can be started, driving a set of transmission sprockets 11 inside the fixing cover 6 to rotate. This, in turn, drives the two sets of transmission sprockets 11 to rotate synchronously via the chain 12, and then through the square telescopic rod 9... The transmission sprockets 11 at both ends rotate synchronously, and finally the transmission sprockets 11 drive the fixed sleeve 14 to rotate, thereby driving the pen shell inside the fixed sleeve 14 to rotate for rapid polishing. During polishing, the electric cylinder 18 is first started to push the movable frame 2 to one side. The movable frame 2 pushes the polishing wheel 20 to move through the moving frame 19 so that it fits against the outside of the pen shell. Then, the first drive motor 4 is started to drive the polishing wheel 20 to rotate and polish the outside of the pen. Finally, the first servo motor 3 is started to drive the reciprocating screw 15 to rotate. The reciprocating screw 15 drives the moving frame 19 to reciprocate through the threaded hole 21. The moving frame 19 then drives the polishing wheel 20 to reciprocate and polish the pen shell as a whole.
