２は加工物を研削する砥石である。 The present invention will be explained below with reference to the drawings showing one embodiment thereof. Reference numeral 10 denotes a main body fixing frame, which is attached to the bed 12 of the grinding machine. Reference numeral 14 denotes an index tube, which is cylindrical and rotatably fitted into the main body fixing frame 10. Recesses 16 are formed on the outer circumference of the index tube 14 at positions where the circumference is divided into eight equal parts and at positions where the circumference is divided into six equal parts, and an index pin 18 protruding from the main body fixing frame 10 is fitted into the recesses 16.
This index tube 14 is fixed by a screw 20 attached to the main body fixing frame 10. A coil spring 22 is in contact with the inner periphery of the index tube 14 and has a cylindrical shape as a whole. 24a and 24b are torsion frames, which are fixed to both ends of the coil spring 22 and which are attached to the index tube 1.
4, and is attached so that it can be fixed at any position using screws 26a and 26b. An index tube 1 is provided on the outer periphery of the torsion frames 24a and 24b.
A scale (not shown) is provided to indicate the rotation angle with respect to 4, that is, the torsion angle between both torsion frames. 28
is a main shaft, which is fitted into the inner periphery of a cylinder formed by the coil spring 22 so as to be rotatable in a linear manner. 30
A guide rod is fitted into a radially extending hole 32 provided in the middle portion of the main shaft 28, and is projected outward from the main shaft 28 by a spring 34. Note that spring 3
The center end of the main shaft 28 of No. 4 is supported by a ball 36. The protruding end of the guide rod 30 fits into a groove between the coil springs 22. One end of the main shaft 28 is rotatably connected to a rack shaft 38.
is fitted into a pedestal 40 attached to the bed 12. The rack 42 formed on the rack shaft 38 is
The handle 4 meshes with the pinion 44 attached to the pedestal and is therefore attached to the pinion 44.
6, the rack shaft 38, that is, the main shaft 38, moves linearly via the pinion 44 and the rack 42. At the other end of the main shaft 28 is a workpiece 48 such as a drill blade.
A chuck 50 is attached for gripping. 5
2 is a grindstone for grinding the workpiece.
