Conventionally, the polishing of curved surfaces of deformable objects relied entirely on the operator's intuition, requiring an extremely high degree of skill.In other words, the success or failure of the polishing work was determined by this curved surface polishing, so this curved surface polishing was This was a major bottleneck in polishing work.

The present invention solves this major problem all at once, and because it is configured as described above, it has the following features.

- Fit the deformable device 11 onto the support body 12, slide the left and right slide tables 5 using the lever 4, set the slide limit position to the bending start position of the deformable device 11, and then slide the support table 8 slightly back and forth; Motor stand 1
In other words, the support body 12 is moved on the X-Y plane to align the center of curvature R of the deformable device 11 with the axis of the fulcrum shaft 6, and then the lever 4 is reversed. Just shake it to complete the preparation.

That is, in this state, when the switch of the puff board 13 and the motor 9 are turned ON and the operator presses down the foot lever 2 with his/her foot, the front and rear slide table 3 moves forward and the deformable device 11 and the puff board 13 are brought into contact with each other. Then, by swinging the lever 4 (toward the right in this figure) and sliding the left and right slide bases 5 to the right, polishing work on the straight outer circumferential surface of the deformable instrument 11 whose generatrix is straight begins. become.

Later, when the polishing work on the straight outer circumferential surface is completed and the puff machine 13 reaches the position where the deformable object 11 starts to curve, the left and right slide tables 5 are prevented from sliding at the slide limit, and in this state, the next rotation is started. When the plate 7 is rotated, the rotating plate 7 matches the curvature R of the deformable device 11, and the rotating plate 7 rotates around the fulcrum shaft 6, so that the curved surface of the deformable device 11 is accurately aligned with the puff board 13. It will be pressed together and polished.

Then, move your foot away from the foot lever 2 and move the front and back slide platform 3.
is moved backward, and then the lever 4 is swung (towards the left in this figure) to return the left and right slide tables 5 to their original positions and the deformable device 11 is removed.

By repeating this operation, the deformable utensil 11 can be sequentially polished using the puff machine 13.

Therefore, what kind of transformed object 1! However, at the start of work, the center of curvature R of the deformable utensil 11 and the fulcrum axis 6 are aligned, and the rest is a simple operation of rotating the rotary plate 7. Polishing of the curved surface of the deformable utensil 11, which has been considered difficult in the past, is now possible. This can be done sequentially.

2 Furthermore, the pressure force between the puff board 13 and the deformable device 11 is also constant because the deformable device 11 aligns with the puff board 13,
Since the polished surface, which is a beautiful mirror surface, is exposed, a product with extremely high commercial value can be obtained.

3. Moreover, since it is only necessary to rotate the rotating plate 7, the polishing work can be performed very quickly and with high efficiency.

4 At the same time, since the outer circumferential surface where the generatrix of the deformable object 11 is linear and the outer circumferential surface where the curved line, that is, the curved surface, can be polished continuously, discontinuous polishing scars (grinding scratches) that occur at these boundaries are not carved. This results in a more beautiful polished surface.

5. Furthermore, since the entire structure is simple, it is easy to manufacture and can be packed compactly, which means that it can be manufactured at a lower cost.

As described above, according to the present invention, curved surfaces of deformable utensils (such as pots, fonge pots, kerators, trays, pots, etc.) can be polished easily and beautifully and precisely without leaving any polishing scratches. Therefore, it is possible to provide an apparatus for polishing the outer peripheral surface of a deformable vessel that exhibits practical effects.
