Abstract

PROBLEM TO BE SOLVED: To provide a polishing device capable of polishing a three-dimensional free curved surface and eliminating adverse influence on a polishing tool by polishing fluid, with an extremely simple constitution. SOLUTION: A rotary shaft 10 and a polishing pad 21 of the polishing device 1 are connected by a connection means 22. The connection means 22 seals fluid 24 in a cell 23 made of a flexible film, oscillatably supports the polishing pad 21 and transmits rotation of the rotary shaft 10 to the polishing pad 21. When a surface 2 to be polished is the three-dimensional free curved surface, the cell 23 is deformed and the polishing pad 21 is oscillated, and thereby the polishing pad 21 exactly goes along with inclination of the surface 2 to be polished.

2. Description of the Related Art Various devices have been conventionally proposed for polishing a three-dimensional free-form surface. For example, Japanese Patent Fair 6-75
The following device is described in Japanese Patent No. 822. That is, a die, which is a workpiece, is placed on the die placement table, and the die is rotated, tilted, and moved in the XY directions through the die placement table. On the other hand, the polishing tool supports the polishing head and gives movement in the Z direction. The polishing tool does not change its horizontal position and angle, but the mold is moved so that the curved surface follows the polishing tool. Then, the polishing is performed by selectively using the contact polishing in which the polishing tool is brought into contact with the mold and the non-contact polishing performed while supplying the abrasive grain liquid through the hole in the center of the polishing tool.

The apparatus described in Japanese Patent Publication No. 6-75822 mentioned above enables precise polishing of a three-dimensional free curved surface, but has a drawback that it requires a large-scale apparatus.
In particular, since the curved surface shape is made to follow the polishing tool by moving the workpiece without changing the horizontal position and angle of the polishing tool, the supporting mechanism and control are complicated and the cost is high. In addition, since the workpiece has to be moved around the mounting table, energy consumption is large.

Japanese Unexamined Patent Publication No. 2000-117609 describes a polishing apparatus of a different type. That is, the grindstone of the polishing tool is made to have a variable angle so as to follow the curved surface of the object to be polished. This is realized by configuring the polishing tool with a tool fixing portion and a tool supporting portion, and bringing them into contact with each other in a spherical shape portion so that the tool fixing portion having a grindstone can change the angle. Rotational transmission from the tool supporting portion to the tool fixing portion is performed by a flexible connecting member such as a coil spring, a diaphragm, or a mesh-shaped body.

In the apparatus described in the above-mentioned Japanese Patent Laid-Open No. 2000-117609, since the grindstone changes its angle by itself, if the relative position between the grindstone and the object to be polished is changed while the wheel is brought into contact with the object to be polished under a constant load. Even if the partner is a three-dimensional free-form surface, polishing can be performed. As a result,
It is possible to obtain a three-dimensional free-form curved surface polishing apparatus which is very low in cost as compared with the apparatus described in Japanese Patent No. 5822. However, this device requires a tool fixing portion and a tool supporting portion that are in contact with each other in a spherical shape portion, and thus the structure cannot be said to be sufficiently simple. Further, a polishing liquid is used for polishing, but this cannot prevent the connector from getting wet. When the polishing liquid adheres to the connector, if the material of the connector is, for example, spring steel, rust naturally occurs. Even if the connector is made of a material that does not generate rust, the abrasive grains, which are the constituents of the polishing liquid, are gradually deposited and solidified in the gaps, and smooth expansion and contraction is hindered.

Next, the operation of the polishing apparatus 1 will be described. When the polishing pad 21 is pressed against the surface to be polished 2 with a predetermined pressure while supplying the polishing liquid to the surface to be polished 2, the polishing pad 21 becomes a shape in which the abrasive grains in the polishing liquid are held, and the preparation for polishing is completed. When the rotary shaft 10 is rotated while continuously supplying the polishing liquid, the rotation is transmitted to the polishing pad 21 via the connecting means 22, and the polishing pad 21 polishes the surface 2 to be polished by the abrasive grains held by the polishing pad 21. By moving the rotary shaft 10 within a horizontal plane, the entire surface 2 to be polished can be polished. According to the Pascal principle, the pressure exerted by the polishing pad 21 on the surface to be polished 2 becomes substantially uniform over the entire surface of the polishing pad 21.

When the surface to be polished 2 is a three-dimensional free curved surface as shown in FIG. 2, the connecting means 22 is deformed and the polishing pad 21 is swung. As a result, the polishing pad 21 closely follows the inclination of the surface to be polished 2. Therefore, the three-dimensional free-form surface can be polished without changing the angle of the rotary shaft 10.

During the polishing operation, the polishing liquid is supplied to the surface 2 to be polished, and the polishing liquid inevitably adheres to the connecting means 22. If a coil spring, a diaphragm, a mesh-shaped body or the like or a perforated body such as a sponge is used as the connecting means, there is a problem that the constituent components of the polishing liquid enter the gaps between the portions to be deposited and solidified to prevent expansion and contraction. Occur. However, in the case of the connecting means 22, there is no gap in the cell 23 where the constituents of the polishing liquid are deposited and solidified. Therefore, the situation in which the polishing liquid hinders the movement of the connecting means 22 does not occur. Further, the connecting means 22 has no problem of rust.

The cell 23 may be made of any material as long as it does not allow passage of fluid and has appropriate strength and flexibility. The fluid 24 may be liquid instead of gas. In the case of gas, the volume change due to the temperature change is large, so that if the temperature inside the cell 23 rises, the internal pressure of the cell 23 also rises and the rigidity of the connecting means 22 increases, but in the case of a liquid, the volume change due to the temperature change is small. Even if the temperature inside the cell 23 rises, the internal pressure of the cell 23 does not rise so much. That is, it is possible to obtain the connecting means 22 in which the rigidity change due to the temperature difference is small.

In addition, since the connecting means has no gap through which the polishing liquid penetrates, the constituent components of the polishing liquid do not deposit and solidify, and smooth movement can be obtained for a long period of time.
