Abstract
A feed apparatus for a grinding machine including a bed, a swivel base rotatably mounted on the bed, a wheel support slidably mounted on the swivel base for sliding movement in a direction slanted by a predetermined angle with respect to a radial direction of a workpiece. The feed apparatus comprises a transmission shaft operatively connected to the wheel support and received in the swivel base thereof to be slidable in the same direction as the sliding movement of the wheel support, means movable in the radial direction of the workpiece, driving means for moving the movable means, and means arranged between the transmission shaft and the movable means for transmitting movement of the movable means in the radial direction of the workpiece to the wheel support through the transmission shaft.
Claims11
A feed apparatus for a grinding machine including a bed, a swivel base rotatably mounted on said bed, a wheel support slidably mounted on said swivel base for sliding movement in a direction oriented by a predetermined angle with respect to a radial direction of a workpiece, comprising:
- a transmission shaft operatively connected to said wheel support and being movable in the same direction as the sliding movement of said wheel support;
- means movable in the radial direction of said workpiece;
- driving means for moving said movable means;
- and
- transmitting means arranged between said transmission shaft and said movable means for transmitting movement of said movable means in the radial direction of the workpiece to said wheel support through said transmission shaft in such a manner as to be movable on said movable means relatively in the axial direction of said workpiece in proportion to movement of said movable means in the radial direction of said workpiece.
A feed apparatus according to claim 11 further comprising a hydraulic cylinder provided in said wheel support, a piston rod thereof being held in contact with one of said transmitting shaft to effect a rapid feed movement of said wheel support.
