The gain effect of the invention is as follows:
structurally: the equipment polishing wheel is vertically installed, so that the occupied area is small compared with that of a traditional horizontal polishing machine, and the space is saved; the equipment adopts an automatic finishing polishing wheel and an automatic feeding and discharging mechanism, so that the online production of the equipment is met, and the labor is saved; the polishing wheel can be automatically trimmed, the consistency after trimming is ensured, the beat is saved, and the workload of workers is reduced; the touch screen is used as a manual interface, so that the operation is simplified, and meanwhile, the setting of operation data is more flexible, so that the polishing requirements of different workpieces can be met; the inside of the equipment adopts a slope type welding technology, so that the complete backflow of the polishing solution is ensured, the accumulation of polishing scraps is avoided, and the cleaning of the equipment is simpler; the adopted polishing wheel fixing mechanism has certain floating amount, and can ensure that the polishing wheel can be completely attached to the rack in the whole polishing process.
In terms of control: the pressure sensor is used to effectively control the pressure value applied to the rack by the polishing wheel, so as to prevent the rack from being bent; the servo motor is used as a power source for rack rotation, so that the rotation angle of the back of the tooth profile can be polished, and the slow rotation of the shaft of the polishing rack can be met.
On the selection of polishing materials: the nylon resin wheel is adopted, so that the rack can not be damaged when the rack is polished.
