Abstract
There is disclosed a roller burnishing apparatus including a first member moved relative to an object to be burnished, a second member movable relative to the first member in a relative movement direction, a burnishing roller held by the second member such that the burnishing roller is rotatable, a biasing device which biases with a biasing force the second member relative to the first member in one of two opposite directions along the relative movement direction, and a pressing-force detecting device that detects a pressing force with which the burnishing roller is pressed against the object and which is based on the biasing force of the biasing device.
Claims21
A roller burnishing apparatus comprising:
- a first member moved relative to an object to be burnished;
- a second member movable relative to the first member in a relative movement direction;
- a burnishing roller held by the second member such that the burnishing roller is rotatable;
- a biasing device which biases with a biasing force the second member relative to the first member in one of two opposite directions along the relative movement direction;
- a pressing-force detecting device that detects a pressing force with which the burnishing roller is pressed against the object and which is based on the biasing force of the biasing device;
- and
- a relative-movement-direction defining mechanism which defines the relative movement direction in which the second member is movable relative to the first member,
- wherein the pressing-force detecting device includes a detecting portion disposed in series with the biasing device and between the first member and the second member.
A roller burnishing apparatus comprising:
- a first member moved relative to an object to be burnished;
- a second member movable relative to the first member in a relative movement direction;
- a burnishing roller held by the second member such that the burnishing roller is rotatable;
- a biasing device which biases with a biasing force the second member relative to the first member in one of two opposite directions along the relative movement direction;
- a pressing-force detecting device that detects a pressing force with which the burnishing roller is pressed against the object and which is based on the biasing force of the biasing device;
- a tool holding portion which detachably holds at least the burnishing roller and the second member;
- an object holding portion which holds the object;
- a relative movement device which moves the tool holding portion and the object holding portion relative to each other by a numerical control;
- and
- a relative rotation device which rotates the object holding portion and the tool holding portion relative to each other.
A roller burnishing apparatus comprising:
- a first member moved relative to an object to be burnished;
- a second member movable relative to the first member in a relative movement direction;
- a burnishing roller held by the second member such that the burnishing roller is rotatable;
- a biasing device which biases with a biasing force the second member relative to the first member in one of two opposite directions along the relative movement direction;
- and
- a pressing-force detecting device that detects a pressing force with which the burnishing roller is pressed against the object and which is based on the biasing force of the biasing device;
- wherein the first member also holds a burnishing roller such that the burnishing roller is rotatable, the apparatus further comprises a holding member which holds the first member and the second member such that the two burnishing rollers respectively held by the first member and the second member are movable toward and away from each other, and the biasing device biases the first member and the second member in respective directions to move the two burnishing rollers in respective directions opposite to each other.
