Abstract
Provided is a bearing insertion apparatus in which a movable carriage is provided on a base placed on a floor surface in a manner of being movable in a horizontal Z-axis direction corresponding to a direction in which the movable carriage moves toward or away from a housing. In addition, an apparatus main body for supporting a rolling bearing at a distal end thereof is supported such that the apparatus main body can be freely moved, by a guide mechanism, with respect to the movable carriage in a horizontal X-axis direction orthogonal to the Z-axis direction and in a vertical Y-axis direction orthogonal to both of the Z-axis direction and the X-axis direction.
Claims4
A bearing insertion apparatus comprising:
- a base;
- a movable carriage provided to be movable in a horizontal Z-axis direction on the base;
- and
- an apparatus main body supported to be freely movable in a predetermined direction with respect to the movable carriage, wherein:
- the apparatus main body includes:
- an elongated hollow cylinder-shaped outer ring supporting cylinder having a distal end surface that is brought into contact with a side surface of an outer ring constituting a rolling bearing such that positioning of the rolling bearing in the Z-axis direction is performed;
- and an inner ring clamping mechanism gripping an inner peripheral surface of an inner ring constituting the rolling bearing by expanding and contracting a clamp main body provided at a portion protruding from a distal end of the outer ring supporting cylinder;
- and
- the apparatus main body is structured to be freely movable with respect to the movable carriage by being guided by a guide mechanism in a horizontal X-axis direction orthogonal to the Z-axis direction and in a vertical Y-axis direction orthogonal to both of the Z-axis direction and the X-axis direction, and the apparatus main body is floatingly supported in a state of being movable in the Y-axis direction within a predetermined range.
