Description

TECHNICAL FIELD

[0001] The utility model mainly relates to the abrasive wheel finishing technical field, concretely is a kind of automatic compensation's abrasive wheel finishing device. BACKGROUND

[0002] Abrasive wheel is constantly worn when constantly polishing workpiece during polishing processing, and error will be generated to polished workpiece after long-time wear of abrasive wheel, and even the situation of polishing workpiece is not appeared.

[0003] Therefore, in the polishing process, abrasive wheel needs to be continuously fed to meet the requirement of accurate finishing of abrasive wheel, and the size of feeding amount each time will depend on the experience of operator, if the feeding amount is small, it needs to be fed many times, which affects efficiency, and if the feeding amount is large, it can cause damage to abrasive wheel dresser, and too large feeding amount can cause explosion of abrasive wheel, which causes harm to person.

[0007] Preferably, the driving assembly comprises a servo motor, the servo motor is arranged on the base, a lead screw is arranged at the output end of the servo motor, and the lead screw is rotatably connected inside the base.

[0008] Preferably, the recording assembly comprises a sliding plate, the sliding plate is arranged on the base, a moving block is arranged on the sliding plate, and the moving block is threadedly connected to the lead screw.

[0009] Preferably, a guide rail is arranged on the base, a sliding block is arranged on the sliding plate, and the sliding block is arranged on the guide rail.

[0010] Preferably, the recording assembly further comprises a top block, the top block is arranged on the sliding plate, and a displacement recorder is arranged above the sliding plate.

[0011] Preferably, one side of the grinding wheel body is attached to the workpiece, and the other side of the grinding wheel body is attached to the displacement recorder.

[0012] Compared with the prior art, the beneficial effects of the utility model are as follows: when the grinding wheel body starts to grind, the displacement recorder is in contact with the grinding wheel body; when the grinding wheel body grinds the workpiece and produces wear, the thickness of the grinding wheel body will become thinner, at which time the contact between the grinding wheel body and the workpiece becomes smaller or even directly not in contact with the workpiece, and the displacement recorder is not in contact with the grinding wheel body; the driving assembly drives the displacement recorder to move to be attached to the grinding wheel body again, and the distance moved by the displacement recorder at this time (this distance is the wear of the grinding wheel body, the grinding wheel body is circular, and the wear is basically the same in one circle through rotation and grinding, so the distance between the displacement recorder and the grinding wheel body is basically the same as the distance that the grinding wheel body needs to contact the workpiece) is recorded; then the grinding wheel body and the displacement recorder are moved at the same time, at which time the grinding wheel body moves the distance that the displacement recorder has just moved, at which time the grinding wheel body can be precisely driven to adjust the feed, which is convenient for the operator to operate.

[0013] Moreover, the position of the displacement recorder is adjusted to record the distance moved by the displacement recorder when the displacement recorder is attached to the grinding wheel body, to calculate the distance that the grinding wheel body needs to move to compensate for the wear of the grinding wheel body, to replace the direct compensation for the wear of the grinding wheel body by moving the grinding wheel body, so that even if the displacement recorder is damaged, no big accident will occur, and if the grinding wheel body is directly moved, the grinding wheel body will burst if the distance moved is too much, so the safety of the compensation adjustment of the grinding wheel body is improved, and the direct movement of the grinding wheel body requires experienced operators, and even workers without rich operation experience can slowly operate by moving the displacement recorder.

[0014] Moreover, according to the characteristics of different grinding wheels, a servo motor torque database can be preset in the numerical control system; an operator only needs to call different torque data to complete the dressing work of different grinding wheels; and workers without rich operation experience can also realize accurate feed amount according to the wear of the grinding wheel body.
