Similarly, the contact position of the second rotary grinding wheel from the obliquely upward direction to the workpiece end 31 in the second step is held constant, and further, the front surface of the workpiece end 31 in the third step is maintained. The contact position of the rotating grinding wheel from the direction is kept constant.

Since the workpiece traveling guide 70 regulates the protruding distance of the end portion 31 of the workpiece to be constant, the respective position settings of the first rotating grinding wheel 40, the second rotating grinding wheel 50, and the rotating polishing wheel 60 that are in contact therewith are set. Thus, it becomes possible to adjust or preset the grinding amount / polishing amount of each burr.
The first rotating grinding wheel 40, the second rotating grinding wheel 50, and the rotating polishing wheel 60 are rotationally driven by individual motors, and the rotational speed and the rotational direction can be arbitrarily adjusted by electric control, respectively, and the individual actuators. Thus, the installation angle of each rotary shaft 42, 52, 62 can be controlled and the press of each disk-shaped rotary grindstone 41, 51, 61 to the workpiece end 31 can be finely adjusted.
As described above, the rotation speed, rotation direction, contact angle, and contact pressure when the first rotating grinding wheel 40, the second rotating grinding wheel 50, and the rotating polishing wheel 60 are in contact with the workpiece end 31 are finely adjusted. By being able to do so, burrs can be reliably and minimally removed and finished in accordance with the shapes of various workpieces and the occurrence of burrs, so product quality after removal of burrs is not reduced.

  Moreover, the workpiece | work 30 is mounted in the upstream of the belt conveyor 20, and is conveyed horizontally, and moves to the downstream of the belt conveyor 20 through a 1st process-a 2nd process-a 3rd process. At this time, the conveyance speed of the belt conveyor in each of the first to third steps of the work 30 can be adjusted in accordance with the shape of the work and the occurrence of burrs. By adjusting the conveying speed of the belt conveyor in each process, the grinding / polishing time by the first rotating grinding wheel, the second rotating grinding wheel and the rotating polishing wheel can be adjusted. The optimum conditions can be set.

Reversing means. The transport speed adjusting means and the transport direction reversing means can be performed manually, but include a memory for electrically storing an optimum adjustment value in accordance with the shape of the work to be deburred and the shape of burrs. It is also possible to automatically execute the optimum value location from the memory.
Further, the first rotating grinding wheel, the second rotating grinding wheel, and the rotating polishing wheel are driven to rotate by individual motors, and each motor is electrically controlled so that the rotation speed can be arbitrarily adjusted. It is an adjustment means. Further, the joint angle adjusting means for finely adjusting the joint angles of the first rotating grinding wheel, the second rotating grinding wheel, and the rotating polishing wheel with respect to the workpiece end portion includes the first rotating grinding wheel, the second rotating grinding wheel, This is carried out by electrically controlling motor-controlled actuators respectively provided on the rotating grinding wheel.

It is also possible to call the optimum value location from the memory automatically.

As the first rotating grindstone, the second rotating grindstone, and the rotating polishing grindstone, a commercially available disk-shaped rotating grindstone (disc grindstone) for a small disc grinder can be used. Normally, a disc grindstone having the same particle size is used as the first rotating grindstone and the second rotating grindstone, but the first rotating grindstone and the second rotation depend on the part and size of the burr generated at the end of the workpiece. With the grinding wheel, it is possible to use the disc grindstone with the optimum particle size.
Similarly, the rotary grinding wheel can be a disc-shaped rotary grinding wheel (disc grinding stone) for small disc grinders that are commercially available, and removes secondary burrs and finish polishing. Select a disc grinding stone with a finer grain size. And use it.

Conventionally, a large-scale deburring device is used for deburring a large workpiece, and a large amount of capital is required for capital investment. On the other hand, for deburring relatively small to medium-sized workpieces, a deburring apparatus having an appropriate size is not commercially available, and manual deburring using a hand-held disc grinder has been common. This required the skill of the operator, and the finished quality was not necessarily good.
According to the deburring method and the deburring device of the present invention, the optimum conditions can be set according to the deburring state of the workpiece, so that the skill of the operator is not required and the deburring with good finished quality is shortened. A large amount can be processed in time, and labor costs can be significantly reduced.
