Description

Technical Field

[0001] This invention relates to the field of aluminum disc polishing technology, and in particular to a polishing machine for the surface of aluminum discs. Background Technology

[0002] Aluminum discs are widely used in industries such as electronics, daily chemicals, pharmaceuticals, auto parts, electrical appliances, insulation, machinery manufacturing, automobiles, aerospace, military, molds, construction, and printing. They are also commonly seen in our daily lives, for example, in can sealing, non-stick pot bottoms, traffic signs, and lamp shades.

[0003] Chinese patent application CN218254504U discloses an aluminum disc polishing machine, including a base, a rotating disk, a motor, and a grinding assembly. The rotating disk is rotatably mounted on the upper surface of the base. The motor is connected to the rotating disk. Several placement slots are evenly arranged along the circumference of the rotating disk, and aluminum discs are placed in these slots. The grinding assembly is positioned at the edge of the base to accommodate the aluminum discs. The plane of the rotating disk is angled to the horizontal plane. A surrounding plate is mounted on the upper surface of the base to accommodate the rotating disk. A grinding opening is formed on the surrounding plate. The grinding assembly is positioned to accommodate the grinding opening. The placement slots are located downwards from the upper surface of the rotating disk and are positioned at the edge of the rotating disk. Compared with existing technologies, the angled arrangement of the rotating disk's plane to the horizontal plane and the surrounding plate facilitate the loading and unloading operations during aluminum disc polishing, thus improving production efficiency.

[0004] The above device enables rapid loading and unloading of aluminum discs during grinding. However, it can only polish the sides of the aluminum discs, which is quite limited. Existing flat polishing devices, if they need to polish both sides of the aluminum discs, generally require manual flipping of the discs after polishing one side, which still requires a lot of manpower. Therefore, this paper proposes a polishing machine for aluminum discs that can automatically flip the discs to solve the above problems. Summary of the Invention

[0005] To address the aforementioned problems, the present invention provides a polishing machine for the surface of aluminum discs.

[0006] The present invention provides a polishing machine for the surface of aluminum discs, which adopts the following technical solution:

[0007] A polishing machine for the surface of aluminum discs includes a base plate, two vertical plates fixedly connected to the top of the base plate, a placement mechanism between the two vertical plates, a movable seat on the top of the base plate, and a polishing mechanism on the movable seat.

[0008] The placement mechanism includes a platform plate disposed between two vertical plates.

A first gear 398 is fixedly connected to the outside of each of the two round rods 393. The two first gears 398 mesh with the two racks 397 respectively.

[0044] A second electric push rod 399 is fixedly connected to the inner side of the support plate 395. The second electric push rod 399 extends into the moving plate 396 and is fixedly connected to the moving plate 396. The aluminum disc workpiece can be placed inside the placement groove 32. During placement, the first support plate 36 or the second support plate 37 can be controlled to extend into the placement groove 32 to provide support for the aluminum disc. At this time, the aluminum disc can be polished. After the polishing is completed, the first support plate 36 and the second support plate 37 can be controlled to extend into the placement groove 32. Then, the platform plate 31 is controlled to rotate 180 degrees to change the surface. After changing the surface, the first support plate 36 and the second support plate 37 at the top of the aluminum disc are moved to one side of the placement groove 32, and the new surface can be processed. The surface changing process does not require much manual intervention, which greatly saves manpower.

[0045] The platform plate 31 has a through groove 381, which is located on both sides of the placement groove 32 and is connected to the adjacent through groove 381. A clamping block 382 is slidably connected inside the through groove 381. An auxiliary plate 383 is fixedly connected inside the through groove 381.

A spring 386 is fixedly connected between the trapezoidal block 385 and the auxiliary plate 383. The spring 386 is located outside the limit rod 384. A stabilizing rod 387 is fixedly connected to the top and bottom of the platform plate 31 and passes through the control plate 39. The spring 386 exerts an elastic force on the trapezoidal block 385, causing the trapezoidal block 385 to remain away from the placement groove 32.

[0046] The placement mechanism 3 includes auxiliary components, including a support plate 388, which is fixedly connected to the frame plate 394. A first motor 389 is fixedly connected to the top of the support plate 388, and a second gear 371 is fixedly connected to the first motor 389 through an output shaft. A gear ring 372 is fixedly connected to the outside of the platform plate 31. The second gear 371 meshes with the gear ring 372. When the second gear 371 rotates, it can drive the gear ring 372 to rotate. A receiving frame 373 is fixedly connected between the two vertical plates 2, and a buffer net 374 is fixedly connected to the bottom of the receiving frame 373. After the aluminum disc is processed, it is placed downward into the receiving frame for storage.

[0047] The polishing mechanism 5 includes a lifting plate 51, which is located on the top of the movable seat 4. The lifting plate 51 extends into the interior of the movable seat 4 and is slidably connected to the movable seat 4. A third electric push rod 52 is fixedly connected to the bottom of the lifting plate 51 and is fixedly connected to the interior of the movable seat 4. A function plate 53 is fixedly connected to the top of the lifting plate 51. An installation plate 54 and a movable block 55 are respectively provided on the top of the function plate 53.

[0048] A second motor 56 is fixedly connected inside the movable block 55. The second motor 56 is fixedly connected to a rotating rod through an output shaft. A polishing head 57 is fixedly connected to the bottom of the rotating rod. A third motor 58 is fixedly connected to the bottom of the function plate 53. A square rod 59 is fixedly connected to the third motor 58 through an output shaft. The square rod 59 matches the rectangular groove 38. A strip plate 591 is provided on the outside of the square rod 59. A fourth electric push rod 592 is fixedly connected to the bottom of the strip plate 591. The bottom of the fourth electric push rod 592 is fixedly connected to the function plate 53. Two extrusion blocks 593 are fixedly connected to the top of the strip plate 591. The polishing head 57 polishes the outside of the aluminum disc.

[0049] Mounting plate 54 extends into the interior of function plate 53 and is slidably connected to function plate 53. Placement frame 594 is slidably connected to the top wall of mounting plate 54. The top of movable block 55 extends into the interior of placement frame 594 and is slidably connected to placement frame 594. Threaded rod 595 is rotatably connected inside placement frame 594. Threaded rod 595 passes through movable block 55 and is threadedly connected to movable block 55. Fourth motor 596 is fixedly connected to the outside of placement frame 594. Fourth motor 596 is fixedly connected to threaded rod 595 through output shaft. After threaded rod 595 rotates, it can drive movable block 55 to move.

[0050] An integrally formed connecting plate 597 is formed on the mounting plate 54. The connecting plate 597 extends outward from the outer side of the functional plate 53. A fifth electric push rod 598 is fixedly connected to the bottom of the connecting plate 597. The bottom of the fifth electric push rod 598 is fixedly connected to the functional plate 53. After the fifth electric push rod 598 is working, it can push and pull the connecting plate 597 up and down. A sixth electric push rod 599 is fixedly connected to the inside of the top wall of the mounting plate 54. One end of the sixth electric push rod 599 is fixedly connected to one side of the placement frame 594. After the sixth electric push rod 599 is working, it can push and pull the placement frame 594. Two rectangular plates 581 are fixedly connected to the top of the base plate 1. The movable seat 4 is set between the two rectangular plates 581. A guide rod is fixedly connected between the two rectangular plates 581. The guide rod passes through the movable seat 4. A seventh electric push rod 582 is fixedly connected between the movable seat 4 and one of the rectangular plates 581. The guide rod provides guidance for the movable seat 4 to maintain linear movement.

[0051] In actual operation, the device is first powered on. After the first electric push rod 391 operates, it drives the control plate 39 to move. After the control plate 39 moves, it drives the push-pull rod 392 to flip. After the push-pull rod 392 flips, it can drive the first connecting plate 34 and the second connecting plate 35 to move. This causes the first connecting plate 34 and the second connecting plate 35 to drive the first tray 36 and the second tray 37 to move respectively. This causes the first tray 36 and the second tray 37 to move into the placement groove 32 or to one side of the placement groove 32. When the first tray 36 or the second tray 37 moves... When the pallet 37 is at the bottom, the first pallet 36 or the second pallet 37 below can be moved into the placement slot 32 by the above operation. The aluminum disc can then be placed in the placement slot 32. After placement, the first motor 389 works and drives the second gear 371 to rotate. The second gear 371 drives the gear ring 372 to rotate. The gear ring 372 drives the platform plate 31 to rotate. During the rotation of the platform plate 31, the aluminum discs in different placement slots 32 pass through the corresponding horizontal positions of the polishing head 57 in sequence, and can be polished in sequence.

[0052] After the aluminum discs are positioned in the processable position, the seventh electric push rod 582 pushes the movable seat 4. The movable seat 4 moves the lifting plate 51, which in turn moves the function plate 53. The function plate 53 then moves the mounting plate 54, the third motor 58, and the push rod. When the square rod 59 moves to a position directly below the rectangular slot 38, the third electric push rod 52 pushes the lifting plate 51 upwards. The lifting plate 51 moves the function plate 53, which then inserts the square rod 59 into the rectangular slot 38. The third motor 58 then rotates the square rod 59, allowing it to rotate at the inserted position. When the first pallet 36 or the second pallet 37 rotates, the placed aluminum disc also rotates, so that the processing position can be adjusted during the rotation when processing its side. During the polishing process, the fourth electric push rod 592 pushes the strip plate 591, and the strip plate 591 drives the extrusion block 593 to move. At this time, the extrusion block 593 contacts the inclined surface of the trapezoidal block 385, and as the extrusion block 593 continues to move, it creates a pushing effect on the trapezoidal block 385. The trapezoidal block 385 drives the limiting rod 384 to move, and the limiting rod 384 drives the clamping block 382 to move to clamp the aluminum disc to ensure its stability during processing.

[0053] Finally, during polishing, the sixth electric push rod 599 pushes and pulls the placement frame 594. Through the above connection relationship, it can be seen that this can adjust the horizontal front and back position of the polishing head 57. After the fourth motor 596 works, it drives the threaded rod 595 to rotate. The threaded rod 595 drives the movable block 55 to move. The movable block 55 drives the placement frame 594 to move, thereby adjusting the horizontal position of the polishing head 57. The fifth electric push rod 598 can pull the connecting plate 597. The connecting plate 597 drives the mounting plate 54 to move up and down, thereby adjusting the vertical height of the polishing head 57. Through the above adjustment steps, the polishing head 57 can flexibly polish the outer side of the aluminum disc. The extension groove 33 connected to the placement groove 32 allows the polishing head 57 to enter and polish the side of the aluminum disc.

[0054] After the aluminum disc is polished on one side, repeat the above steps to move the control function board 53 away from the platform plate 31. After ensuring that it does not obstruct the flipping of the platform plate 31, control the first support plate 36 and the second support plate 37 to extend into the placement groove 32 to prevent the aluminum disc from falling out during the flipping process. Then, the second electric push rod 399 works to push the moving plate 396. The moving plate 396 drives the rack 397 to move. The rack 397 drives the first gear 398 to rotate. The first gear 398 drives the round rod 393 to rotate 180 degrees. The round rod 393 also drives the platform plate 396 to rotate 180 degrees. The table 31 is rotated 180 degrees, causing the unprocessed side of the aluminum disc to face upwards. The first support plate 36 or the second support plate 37 above the aluminum disc is moved away from the placement slot 32, allowing the new side of the aluminum disc to be processed. This achieves the purpose of changing the side of the aluminum disc, which is more labor-saving than manual side changing. After all processing is completed, the first support plate 36 or the second support plate 37 at the bottom of the aluminum disc is moved away from the placement slot 32, and the aluminum disc falls into the receiving frame 373 for storage. The buffer net 374 provides cushioning, which enhances safety. This automatic unloading method is more convenient.

[0055] The above are all preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Therefore, all equivalent changes made in accordance with the structure, shape and principle of the present invention should be covered within the scope of protection of the present invention.
