Claims

[Claims for Utility Model Registration] A grinding machine for a bar-shaped workpiece, which is equipped with a chuck 11 at the tip of a driven and rotated spindle 14 for removably fixing a bar-shaped workpiece A to be ground. A centering mechanism 21 is interposed between the chuck 11 and the spindle 14 so that the rod-shaped work A fixed to the chuck 11 is positioned concentrically with the spindle 14. grinding machine. The centering mechanism 21 is connected to the spindle 14
The chuck 11 is equipped with a base 22 that can be attached to the tip of the chuck 11 and that forms a plane 22A perpendicular to the axis _a3 of the spindle 14 in the attached state, and is fixed to the chuck 11. a mounting base 23 forming a plane 23A perpendicular to the axis _a1 of the rod-shaped workpiece A, and the base 2.
2 can be attached to the base 22 while being prevented from moving in the direction along the plane 22A of the two, and can be moved toward the base 22 in the attached state so that both the bases 22
, 23, and an annular fixing member 24 that can be fixed in a non-rotating state by pressing the mounting base 23 against the base 22 so that the flat surfaces 22A, 23A of the mounts 23 are in surface contact with each other, and a ring-shaped fixing member 24 that is attached to a plurality of locations in the circumferential direction of the fixing member 24. When the fixing member 24 is in a state allowing the mounting base 23 to slide relative to the base 22, the chuck 11 is moved along the radial direction toward the axis.
and a plurality of adjustment rods 25 that slide the mounting table 23 relative to the base 22 so that the axis _a1 of the rod-shaped work A fixed to is located on the extension of the axis _a3 of the spindle 14. A grinding machine for a rod-shaped workpiece according to claim 1 of the utility model registration claim. The chuck 11 is attached to the tip of the spindle 14 via the centering mechanism 21, and the rod-shaped workpiece A is held in a position where the rod-shaped workpiece axis _a1 is parallel to or coincides with the extension line of the spindle axis _a3 .
A work holding member 31 is formed with a work holding groove 30 having a V-shaped cross section and can receive and hold a rod-shaped work A while positioning the workpiece A. 31 and a fixing member 33 that presses and fixes the rod-shaped workpiece A received and held by the workpiece holding groove 30 against both inclined inner wall surfaces 30a of the workpiece holding groove 30. grinding machine.
