The working principle is as follows: according to the invention, firstly, a flaky round cake hardware is placed between a disc 6 and a polishing disc 5, two cylinders 2 are driven, the disc 6 and the polishing disc 5 are close to each other and are extruded on the surface of the hardware, a sucker 8 on the disc 6 is adsorbed on one surface of the hardware, the surface does not need to be polished and is the surface attached to the surface of an object, the surface does not need to be polished, then the output end of the cylinder 2 connected with the polishing disc 5 does retraction action, the retraction stroke distance enables the end part of a polishing brush on the surface of the polishing disc 5 to be in contact with the surface of the hardware, then two motors 4 are driven and rotate in opposite directions, then the brush on the polishing disc 5 polishes the surface of the hardware, after polishing is finished, the two cylinders 2 retract and reset, and move to an initial position, the hardware is taken down from the sucker 8, in the taking-down process, an operator can use an end part flaky tool to be inserted into a gap between the sucker 8 and the hardware, the sucker 8 loses a negative pressure environment, and the hardware is taken down; the hardware polishing device designed in the invention is suitable for polishing flaky round-cake-shaped hardware, so that deformation and damage of the hardware caused by radial extrusion force and simultaneous rotation of the two motors 4, namely rotation of the polishing disc 5 and rotation of the hardware, are avoided, and the polishing operation efficiency is ensured;

placing hardware on a material separation mechanism on a material rod 11, driving a screw rod 10 to rotate by an external servo motor to drive the material rod 11 to move, driving a cylinder 2 to clamp the hardware when the hardware is conveyed to the positions of a polishing disc 5 and a disc 6, separating the hardware from the material separation mechanism, and placing the hardware on the material separation mechanism when the material rod 11 synchronously moves to one side of one fixing plate 9; when the material rod 11 moves to one side of one of the fixing plates 9 from the position of the motor 4, hardware is placed, and the material rod 11 carries the hardware to move to the position of the motor 4 again, the hardware is polished to be separated from the material separation mechanism, namely, the hardware is polished and placed at the same time when the hardware is moved, so that the automation degree of the polishing device is improved, and the polishing operation efficiency is improved;

when the material rod 11 moves to one side of the fixing plate 9, the hardware is placed in the grooves 17, the hardware is erected by the two grooves 17, then the hardware is conveyed to a position between the disc 6 and the polishing disc 5 through the material rod 11 and clamped, then the material rod 11 continues to move, the edge of the hardware extrudes the material block 16, the material block 16 rotates around the rotating shaft 15 connected with the material block, the hardware is separated from the material block 16, then the material block 16 is restored to the initial state again under the torsion force of the torsion spring 14, namely the two notches of the grooves 17 are inclined to the middle state, then the hardware is placed in the grooves 17, and the material block 16 supports the hardware frame; the arrangement of the groove 17 on the material block 16 is convenient for placing hardware, an operator can vertically place the hardware in the groove 17, the hardware can be placed between the disc 6 and the polishing disc 5 even if the hardware has a left or right inclination amplitude, and the hardware can be clamped and placed in a vertical state when the disc 6 and the polishing disc 5 are mutually extruded;

the hardware is arranged in the groove 17, the lowest point of the edge of the hardware is lower than the inner bottom surface of the groove 17, so when the hardware is separated from the groove 17, the inner bottom surface of the groove 17 has a tendency of vertically extruding the hardware, the tendency forces the hardware to move upwards, the moving amplitude is the upward deformation quantity of a polishing brush and a suction cup 8 on a polishing disc 5, although the hardware can be separated from the groove 17, the lowest point of the edge of the hardware generates extrusion friction with the inner surface of the groove 17, and the lowest point of the edge of the hardware is seriously extruded and deformed, a sliding block 19 is arranged, so that the hardware extrudes the groove 17, a material block 16 rotates and presses the sliding block 19 downwards, and the sliding block 19 moves downwards along a sliding groove 18, the lowest point of the edge of the hardware is buffered and protected, meanwhile, the friction force between the hardware and the inner bottom surface of the groove 17 is reduced, and the friction damage to the inner bottom surface of the groove 17 is reduced; by arranging the rolling shaft 20, when the hardware is separated from the groove 17, the rubbing rolling shaft 20 rotates to convert the stable sliding friction between the edge of the hardware and the groove 17 into rolling friction, and meanwhile, a rubber layer is arranged on the surface of the rolling shaft 20 to protect the edge of the hardware;

after the hardware is polished, starting an external water pump, injecting water into a water supply pipe 23, enabling clear water to flow into a sleeve 21 through a through hole 22, pushing a push rod 24 to move along a slide hole 27 by water pressure, enabling the other end of a channel 25 to be gradually close to one end of a gas channel 26, when a limiting plate 241 of the push rod 24 in the slide hole 27 is in contact with the inner end of the slide hole 27, communicating the channel 25 with the gas channel 26 at the moment, enabling water to flow into a hose 28 along the gas channel 26 and flow out of a through hole 29 in a suction disc 8, injecting the water into the suction disc 8, enabling the suction disc 8 to lose a negative pressure environment, automatically separating the hardware on the suction disc 8 to drop, stopping water supply by the water supply pump, and resetting the push rod 24 under the elastic force of a connecting spring; due to the arrangement of the sucking disc 8 and the water supply pipe 23, automatic blanking of hardware is realized, an operator does not need to take down the hardware manually, operation is reduced, meanwhile, water flows out of the through hole 29, the sucking disc 8 is moistened by the water, and the effect of the sucking disc 8 on the surface of the hardware is improved;

the water inlet pipe 33 rotates and is communicated with the connecting pipe 31, external water pumps inject polishing liquid into a hollow part in the polishing disc 5 in the polishing process of the polishing disc 5, and the polishing liquid flows out from the overflow hole 30, so that the polishing disc 5 polishes the surface of the hardware while supplementing the polishing liquid, and the polishing quality of the surface of the hardware is improved;

make the mill 5 when rotating, the polishing solution is because of the centrifugal force reason that the 5 rotations of mill produced, make when starting rotation at every turn, pour into the polishing solution, the polishing solution is inhomogeneous in the inside distribution of mill 5, lead to the mill 5 start-up rotation unstable enough, influence the steady operation of motor, set up even body 34 for this reason, back in the mill 5 is poured into to the polishing solution, through body 34 evenly distributed in the mill 5, make every position quality tend to the uniform state in the mill 5, simultaneously after pouring into the polishing solution in the mill 5 into, liquid can evenly distributed to in every body 34, in the mill 5 starts rotation process, guarantee motor operating stability.
