Description

Technical Field

[0001] This utility model belongs to the field of metal polishing technology, and specifically relates to a metal polishing device. Background Technology

[0002] Metal polishing is a finishing process that uses polishing tools and abrasive particles or other polishing media to modify the surface of metal workpieces. Polishing does not improve the dimensional accuracy or geometric accuracy of the workpiece, but aims to obtain a smooth surface or mirror gloss. Polishing wheels are usually used as polishing tools, and polishing wheels are generally made of multiple layers of canvas, felt or leather.

[0003] Existing metal polishing equipment typically operates in a single-station manner. After the polishing wheel finishes polishing a workpiece, personnel are required to unload and load the workpiece. During this process, the polishing wheel is idle, and the machine is usually stopped to save energy. This process is repeated. However, this method not only wastes time but also greatly reduces the polishing rate. Utility Model Content

[0025] This specific embodiment is a metal polishing device, the structural schematic diagram of which is shown below. Figures 1 to 4As shown, the system includes a main body 1, with a protective door 2 at its front end. A multi-station rotation mechanism 3 is installed inside the main body 1. A polishing assembly 4 is installed on the upper part of the main body 1. The multi-station rotation mechanism 3 includes a fixed platform 31, which is fixed inside the main body 1. A rotation assembly 32 is mounted on the upper and lower sides of the fixed platform 31. The rotation assembly 32 includes a fixed frame 321, which is fixed below the fixed platform 31. A first motor 322 is mounted in the middle of the fixed frame 321, and the output end of the first motor 322 is connected to a first transmission rod 323. Lower mounting frames 324 are provided on both sides below the processing table 33, and movable wheels 325 are connected to the bottom of the lower mounting frames 324. A circular guide rail groove 326 is provided around the upper periphery of the fixed platform 31. The movable wheel 325 is connected to the circular guide rail groove 326 above the fixed platform 31 for guided movement. A processing table 33 is fixed above the lower frame 324. Mounting frames 34 are distributed around the upper periphery of the processing table 33. Clamping components 35 are jointly installed inside and outside the multiple mounting frames 34. The clamping components 35 include preset grooves 351, which are distributed on both sides of the middle of the mounting frame 34. A forward and reverse lead screw 352 is installed in the middle of one of the preset grooves 351. A first bevel gear 353 is fixed on one side of the middle section of the forward and reverse lead screw 352. A second bevel gear 354 meshes on one side of the first bevel gear 353. A second transmission rod 355 is fixed in the middle of the second bevel gear 354. A second motor is installed at one end of the second transmission rod 355. 356. Screw sleeves 357 are screwed onto both sides of the middle portion of the positive and negative lead screws 352. A mounting bracket 358 is fixed around and on one side of the screw sleeve 357. A clamping plate 359 is fixed to one end of the mounting bracket 358, and a guide bracket 3510 is fixed to the other side of the clamping plate 359. A guide rod 3511 is fixed inside another pre-set slot 351. The guide bracket 3510 and the guide rod 3511 are connected by a movable guide connection. The operator can pre-place four metal workpieces to be processed in the middle of the four mounting brackets 34 above the processing table 33. Then, the corresponding second motor 356 is started sequentially to rotate the second transmission rod 355 and the second bevel gear 354 at its end. This causes the first bevel gear 353, which interacts with the lead screw, to rotate the positive and negative lead screws 352. The two opposing lead screw sleeves 357, which interact with the lead screw, can move relative to each other, along with their respective fixed mounting brackets 358 and connected clamping plates 359, guided by guide brackets 3510 and guide rods 3511. This allows for the stable clamping of the metal workpiece to be processed. At this point, the operator can start the third motor 45 to drive the polishing wheel 46 to perform surface polishing on the metal workpiece clamped in the middle of one of the mounting brackets 34. After the workpiece is processed, the operator can start the first motor 322 to cause the first transmission rod 323 to rotate the processing table 33 in conjunction with the support of the lower mounting bracket 324, movable wheels 325, and circular guide rail groove 326. This allows unprocessed metal parts to be moved to the processing area, while processed metal parts can be moved to the unloading area.Personnel can simply unload and simultaneously load the material, which improves efficiency and reduces the idle time of the polishing wheel 46.

[0026] The polishing assembly 4 includes an electric push rod 41, which is installed inside the upper part of the main body 1.

Slide rods 44 are fixed on both sides inside the upper part of the main body 1. A third motor 45 is installed inside the assembly frame 42, and the output end of the third motor 45 is connected to a polishing wheel 46. The connecting slides 43 and the corresponding slide rods 44 on both sides of the assembly frame 42 are movably connected. When metal workpieces of different heights are involved, the operator can start the electric push rod 41. Under the guidance of the assembly frame 42, the connecting slides 43, and the slide rods 44, the third motor 45 and the polishing wheel 46 connected to the end can be indirectly lifted and lowered to adapt to different metal workpieces.

[0027] Working principle: The operator can pre-place four metal workpieces to be processed in the middle of the four mounting brackets 34 above the processing table 33. Then, the corresponding second motor 356 is started in sequence to rotate the second transmission rod 355 and the second bevel gear 354 at the end. As a result, the first bevel gear 353, which interacts with the lead screw, can rotate the forward and reverse lead screw 352. As a result, the two opposing lead screw sleeves 357, which interact with the lead screw, can move relative to each other with their respective fixed mounting brackets 358 and connected clamping plates 359, in coordination with the guide brackets 3510 and guide rods 3511. This can stabilize the metal workpieces to be processed. At this time, the operator can start the third motor 45 to drive the polishing wheel 46 to polish the metal workpiece held in the middle of one of the mounting brackets 34. The workpiece undergoes surface polishing. After the workpiece is finished, the operator can start the first motor 322 to make the first transmission rod 323 rotate the processing table 33 in conjunction with the support of the lower frame 324, movable wheel 325, and circular guide groove 326. Thus, unprocessed metal parts can be rotated to the processing area, while processed metal parts can be rotated to the unloading area. The operator can unload them and load them simultaneously, which improves efficiency and reduces the idle time of the polishing wheel 46. Finally, when dealing with metal workpieces of different heights, the operator can start the electric push rod 41. Under the guidance of the assembly frame 42, connecting slide 43, and slide rod 44, the third motor 45 and the polishing wheel 46 connected to the end can be lifted and lowered to accommodate different metal parts.
