The working principle is as follows: when the device works, firstly, a metal plate to be polished is pushed rightwards from the left end of the workbench 1 to enter between the two protection plates 75 until the right end of the metal plate abuts against the reinforcing plate 71, then the metal plate is pushed rightwards, the reinforcing plate 71 drives the connecting rod 73 to move through the connecting plate 72, because the second sliding block 74 is arranged in a limiting sliding groove formed in the inner wall of the workbench 1, and the two ends of the connecting rod 73 are respectively connected with the connecting plate 72 and the second sliding block 74 through hinges, the second sliding block 74 can slide relatively in the limiting sliding groove, at the moment, the second sliding block 74 can drive the protection plates 75 to slide relatively, so that the protection plates 75 on the two sides gradually clamp the metal plate, along with the sliding of the protection plates 75, the moving block 77 can drive the inserting rod 78 to enter the inside of the second fixing plate 6, and simultaneously, under the self elastic force of the third spring 79, the clamping block 710 can enter the inside of the inserting rod 78, then the inserting rod 78 can slide stably towards the inside of the second fixing plate 6, when the metal plate is pushed rightwards and does not move any more, it is indicated that the protection plate 75 has firmly clamped the metal plate and the right side is tightly pressed against the side surface of the reinforcing plate, at this time, the clamping block 710 is stably clamped in the channel formed in the second fixing plate 6, the clamping work of the clamping block 710 is completed, at this time, the protection plate 75 is stably clamped and fixed to the metal plate, then the polishing sheet 34 is pressed against the surface of the metal plate by opening the switch of the hydraulic telescopic rod 33, then the polishing sheet 34 is opened by the built-in power supply of the polishing sheet 34, so that the polishing sheet 34 polishes the metal plate, meanwhile, the external power supply is used for supplying power to the electromagnetic slider 32, thereby the electromagnetic slider 32 can slide stably in the electromagnetic sliding rail 31, so that the polishing plate 34 can be driven to completely polish the surface of the metal plate, and the subsequent treatment of the metal plate is more convenient.

When the work of polishing goes on, open water pump 52 through external power supply, make the inside water source of water tank 51 enter into the inside of delivery port 55 through water pump 52 water pipe 54, carry sheet metal's surface with the water source through delivery port 55 afterwards, make the piece waste material that produces when polishing obtain wetting, then offer through 1 bottom through-hole of workstation, thereby make the piece waste material enter into the inside of water tank 51 through the through-hole, the completion is to the collection processing work of waste material, meanwhile, the piece waste material stays the surface that exists filter 56, make rivers enter into the bottom of water tank 51 through filtering, it is more convenient to make it carry out follow-up use.

After the metal plate is polished, the knob 81 is twisted to enable the rotating rod 82 to drive the rotating wheel 83 to rotate, at this time, the first moving plate 84 can drive the second moving plate 86 to slide through the sliding plate 85, so that the second moving plate 86 abuts against the fixture block 710, under the action of the self elastic force of the third spring 79, the fixture block 710 can enter the inside of the inserting rod 78, then under the action of the self elastic force of the second spring 76, the second spring 76 can drive the protection plate 75 to slide towards the inner wall of the workbench 1, at this time, the protection plate 75 is separated from the metal plate, and simultaneously along with the sliding of the protection plate 75, the protection plate can drive the connecting rod 73 to slide through the second sliding block 74, so that the connecting plate 72 drives the reinforcing plate 71 to slide, then the reinforcing plate 71 abuts against the metal plate, so that the metal plate slides towards the left end of the workbench 1, and the polished metal plate is taken out, the subsequent treatment is more convenient.

After the collection of the scrap is finished, the first sliding block 511 is pressed against the first spring 510 by pressing the pulling block 513, so that the limiting block on the surface of the limiting rod 512 is separated from the limiting groove, and then the pulling plate 57 can drive the filtering plate 56 to be pulled outwards, so that the worker can collect the scrap remaining on the surface of the filtering plate 56 or replace the filtering plate 56, the scrap can be more conveniently processed and used, the cost waste is reduced, and the whole working principle of the invention is described above.
