てある。On the central axis of the upper end of the core member 4, a sphere 6 serving as a fulcrum of rotation is provided in a projecting manner, and the lower end surface is formed into a convex curved surface that draws an arc concentric with the sphere 6. On the central axis of the lower end, a chuck receiving portion 7 formed by a hollow shaft having a thread partially formed on the inner peripheral wall is provided so as to project from the through hole 9 formed in the center of the bottom portion 8. It projects downward and is movably accommodated in the core accommodating portion 10 in the casing.

に当接して底部８に受け止められている。The inner bottom surface of the core accommodating portion 10 is formed into a concave curved surface that fits the lower end surface of the core member 4, and the lower surface has a concave curved surface that rotatably fits with the sphere 6. The seat 11 provided in the above is elastically pressed downward by the spring member 12. As a result, the lower end surface of the core member 4 contacts the inner bottom surface and is received by the bottom portion 8.

周方向に対して一体的に連結している。On the side portion of the casing 3, five support members 13, 13 are elastically pressed by the spring members 14, 14 at right angles to the central axis of the core member 4, from the casing side portion toward the inside of the accommodating portion. The support members 13 and 13 are radially provided so that the tips of the support members 13 and 13 are formed in the recesses 1 on the sides of the core member 4.
5 and 15, the core member 4 is elastically supported vertically by the tip, and the casing 3 and the core member 4 are integrally connected in the circumferential direction.

状に形成した先端面により型面などを研磨する。In the above-mentioned curved surface polishing tool, the mounting shaft 17 is not shown in the drawing, but it can be mounted on a rotating shaft protruding from the lower end of the numerically controlled machine. The rotation is transmitted from the casing 3 to the core member 4 via the support members 13 and 13, and the core member 4 rotates in the circumferential direction together with the casing 3. By this rotation, the chuck member 5 holds the core member 4
The polishing material 2 attached to the mold also rotates in the same direction, and the tip surface formed into a hemispherical surface polishes the mold surface and the like.

いる。The core member 4 is always supported vertically by a large number of supporting members 13, 13 which are radially present. Further, a pressing force larger than the elasticity of the polishing material 2 is applied to the core member 4 so that the core member 4 can cope with a change in the outer shape due to the abrasion of the polishing material 2 during polishing, thereby keeping the pressing margin constant.

押し代が一定に保たれる。The strength of the pressing force due to the unevenness of the polishing surface is automatically adjusted by the expansion and contraction of the spring member 14 due to the vertical movement of the core member 4, but it is too large to give a great load to the rotation of the polishing material 2. At the time of contact pressure, stress concentrates on the ball segment 6 portion of the core member 4, whereby the lower end surface of the core member 4 slides on the inner bottom surface and inclines with the polishing rod 1 as shown in FIG. Due to this inclination, excessive contact pressure is absorbed and the pushing margin is kept constant.

れることになる。Further, since the fitting of the core member 4 and the receiving seat 11 is carried out by the spherical section 6, the inclination direction is unlimited, and the inclination is always supported from five directions by the support members 13, 1 which are elastically supported.
The compressed spring member 14 of No. 3 acts as an immediate push back so that the core member 4 responds immediately in all directions to cope with excessive contact pressure. As a result, the curved surface can be smoothly polished regardless of the size of the undulations.
