The invention aims to provide a sheet metal part polishing device for polishing the edge of a sheet metal part.
In order to achieve the purpose, the technical scheme of the invention is as follows: a sheet metal part polishing device comprises a rack, a motor and at least one polishing mechanism, wherein the polishing mechanism comprises a first rotating shaft, a limiting part, a polishing assembly and a rotating part which are sequentially arranged on the periphery of the first rotating shaft; the frame is provided with two lower pressure springs, one end of each lower pressure spring is fixed on the frame, and the other end of each lower pressure spring is fixed on the limiting piece and the rotating piece respectively; the grinding assembly comprises a roller fixed on a first rotating shaft, a friction layer fixed on the periphery of the roller and a negative pressure piston capable of sliding along the inner wall of the roller, the bottom of the friction layer is equal to the bottom of a limiting piece in height, the negative pressure piston is positioned on the periphery of the first rotating shaft, an electromagnet is fixed on a rack, a first adsorption block is fixed at one end, close to the electromagnet, of the negative pressure piston, a rotating groove with an opening facing the first rotating shaft is formed at one end, far away from the electromagnet, a reset spring and a rotating piston capable of sliding along the rotating groove are arranged in the rotating groove, threads are arranged on the first rotating shaft, a sliding block capable of sliding along the threads is arranged on the rotating piston, a second adsorption block is embedded in the rotating piston, the electromagnet can adsorb the first adsorption block and; a sliding spring and a switch which is positioned at the end part of the roller and can close the electromagnet are arranged in the roller, the switch can rotate by taking the first rotating shaft as the center, and two ends of the sliding spring are respectively fixed on the negative pressure piston and the switch; the side wall of the roller is provided with a plurality of air inlet one-way valves of which air outlet ends are communicated with the inner cavity of the roller, the two end parts of the roller are respectively fixed with an air outlet one-way valve of which the air inlet end is communicated with the inner cavity of the roller, the end part of the roller is fixed with a collecting box, the collecting box is provided with an air outlet and a closable discharge hole, and the collecting box is communicated with the air outlet ends of the air outlet; a filter screen is fixed in the collecting box.
When polishing the sheet metal component, place the sheet metal component in the frame of grinding machanism below earlier to make the locating part press on the sheet metal component, make the cylinder press at the edge of sheet metal component simultaneously, and constantly promote the sheet metal component at the in-process of polishing and remove. Then the motor and the electromagnet are turned on, the motor drives the first rotating shaft to rotate, the roller rotates along with the first rotating shaft, the friction layer polishes the edge of the sheet metal part, and burrs are polished into powder. The electromagnet is opened and then adsorbs the first adsorption block and the second adsorption block, the first adsorption block is always positioned on one side, closest to the electromagnet, of the negative pressure piston under the action of magnetic force, and the negative pressure piston rotates relative to the roller at the moment. The second adsorption block slides towards the first rotating shaft under the action of magnetic force, then the sliding block is attached to the thread, the sliding block slides along the thread, at the moment, the negative pressure piston moves towards one end of the roller, the space in front of the movement of the negative pressure piston is reduced in the process, and air in the negative pressure piston is discharged from the air outlet one-way valve; the space behind the motion of the negative pressure piston is increased, and the outside air is sucked into the roller along with the powder generated by grinding, so that the powder is prevented from being scattered into a workshop. When the slider slided along the screw, sliding spring was elongated, and when sliding spring increased by tensile length, sliding spring increased to the pulling force of switch, the switch was touched by sliding spring, and the electro-magnet was closed, and the rotating piston slides into the rotating groove under reset spring's effect, and negative pressure piston no longer slides along the pivot this moment.
The negative pressure piston is reset under the action of the sliding spring, and in the process, the negative pressure piston slides along the first rotating shaft, and the space volumes on two sides of the negative pressure piston are changed again. And after the length of the sliding spring is reduced, the touch switch is stopped, the electromagnet is turned on again, the negative pressure piston rotates to the position where the first adsorption block is closest to the electromagnet again under the action of the magnetic force of the electromagnet on the first adsorption block, and in the process, the negative pressure piston continues to slide along the rotating shaft for a distance under the action of inertia until the rotating piston slides out again.

The beneficial effect of this scheme does:
the friction layer can polish the edges of the sheet metal parts, dust generated by polishing is continuously sucked into an inner cavity of the roller in the polishing process, and then enters a collecting box along with air to be stored when the volume of the inner cavity is changed, so that the dust is prevented from being scattered into air of a workshop, and the environment of the workshop is prevented from being deteriorated; meanwhile, the phenomenon that the dust is clamped between the friction layer and the sheet metal part to scratch the sheet metal part or clamped into a groove on the surface of the friction layer to cause the polishing effect to be poor is avoided.
When the electromagnet adsorbs the first adsorption block, the first adsorption block is fixed on the negative pressure piston, and the negative pressure piston rotates relative to the roller; when the electro-magnet adsorbed the second and adsorbed the piece, the rotary piston roll-off, because first pivot rotates, the slider can slide one section distance along the screw thread this moment, so last negative pressure piston can slide along first pivot, makes the space volume change of negative pressure piston both sides, then can inhale external air, reaches the effect that prevents dust polluted air.
The bottom of the limiting part is equal to the bottom of the friction layer in height, the limiting part is pressed on the sheet metal part during polishing, and the friction layer can polish burrs higher than the limiting part; when the sheet metal component thickness changes, the height of locating part also changes thereupon, so can polish the sheet metal component of different thickness.
