本発明は、工具主軸の軸線と工作物支持主軸の

種々の球面を工作物上に形成し得るようにした球
面加工装置に関するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention allows various spherical surfaces with different radii to be formed on a workpiece by changing the intersection angle between the axis of the tool spindle and the axis of the workpiece support spindle. The present invention relates to a spherical surface machining device.

とによつて任意の半径Ｒの球面を加工することが
できる。 To machine a spherical surface formed on a workpiece, as shown in Fig. 1a and b, the workpiece W is supported on the tip surface of the workpiece support spindle A, and the tip is placed at a position offset from the rotation center line S. The tool spindle B with the tool C attached to the surface is rotated with respect to the workpiece support spindle A so that the rotation center line S of the tool spindle B and the rotation center line P of the workpiece support spindle A intersect at a predetermined angle θ. This is done by rotating both main shafts A and B at the same time after placing the cut and making a predetermined cut. In this case, the workpiece W
The finishing radius R of the spherical surface is expressed as R=r/sinθ, where r is the eccentricity of the cutting edge of the tool C from the rotation center line S, and since r is constant, R1=r/
sin θ1, R2 = r/sin θ2, therefore, by changing θ, a spherical surface with an arbitrary radius R can be machined.

アツプを招き不経済であつた。 By the way, in such spherical machining, since the thickness of the peripheral edge of the workpiece is uniform,
Conventionally, as shown in Fig. 1a and b, a workpiece support is formed by tilting the workpiece support surface by a predetermined angle corresponding to the radius of the spherical surface to be machined with respect to the mounting surface to the workpiece support spindle A. Previously, a plurality of devices were prepared depending on the radius of the spherical surface to be machined, and a workpiece support device suitable for the radius of the spherical surface to be machined was selected and attached to the workpiece support spindle to support the workpiece. If this is done, there is a problem in that a number of workpiece support devices must be prepared depending on the type of spherical surface to be machined. The mounting surface of such a workpiece support device must be machined to have a high level of flatness so that it will not be deformed when the workpiece is fixed by suction, and it is difficult to perform such high-precision machining on multiple workpiece support devices. This led to increased costs and was uneconomical.

The intersection angle of the workpiece support surface formed on the workpiece support axis with respect to the axis of the workpiece support spindle can be changed, and even when machining various spherical surfaces with different radii, the workpiece can be supported with a single workpiece support device. The purpose is to do so.
