Abstract
A fixing band-tightening apparatus comprises a holding section for gripping a shaft section at both ends in an axial direction, the holding section being provided rotatably in a circumferential direction in accordance with a driving action of a rotary driving source, a stopper section arranged in a lateral direction substantially horizontal with respect to the holding section, for positioning a projection of a fixing band in the lateral direction except for a vertical direction, and a band-tightening section for forcibly nipping the projection of the fixing band positioned by the stopper section to tighten the fixing band.
Claims24
A fixing band-tightening apparatus for forcibly nipping and deforming a projection of an annular fixing band loosely fitted to a workpiece having a shaft-shaped configuration so that a diameter of said fixing band is reduced to fix said fixing band to said workpiece, said fixing band-tightening apparatus comprising:
- a holding section for gripping a shaft section of said workpiece at both ends in an axial direction to rotatably hold said workpiece in a circumferential direction in accordance with a driving action of a rotary driving source;
- a stopper section arranged in a lateral direction substantially horizontal with respect to said holding section, for positioning said projection of said fixing band in said lateral direction except for a vertical direction;
- and
- a band-tightening section for forcibly nipping said projection of said fixing band positioned by said stopper section to tighten said fixing band to said workpiece.
A fixing band-tightening apparatus for fixing a boot made of resin to a constant velocity universal joint by installing a large diameter annular attachment section of said boot made of resin formed to have a hollow bellows-shaped configuration to a cup section of said constant velocity universal joint, installing a small diameter annular attachment section of said boot made of resin to a shaft section of an inner member, and forcibly nipping and constricting projections of annular fixing bands loosely fitted to said large diameter annular attachment section and said small diameter annular attachment section respectively, said fixing band-tightening apparatus comprising:
- a holding section for gripping said constant velocity universal joint at both ends in an axial direction to rotatably hold said constant velocity universal joint in a circumferential direction in accordance with a driving action of a rotary driving source;
- and
- end-positioning mechanisms provided for said holding section, for positioning said annular attachment sections of said boot made of resin installed to said constant velocity universal joint at predetermined positions before forcibly nipping said projections of said fixing bands.
The fixing band-tightening apparatus according to claim 21, wherein said bellows section-pressing mechanism includes an actuator, and a pressing plate provided movably back and forth in directions inclined by a predetermined angle with respect to an axis of said shaft section of said inner member in accordance with a driving action of said actuator, and wherein a flat surface section of said pressing plate enters a boundary portion between said small diameter annular attachment section and said bellows section to press said bellows section toward said large diameter annular attachment section.
A fixing band-tightening apparatus for fixing a boot made of resin to a constant velocity universal joint by installing a large diameter annular attachment section of said boot made of resin formed to have a hollow bellows-shaped configuration to a cup section of said constant velocity universal joint, installing a small diameter annular attachment section of said boot made of resin to a shaft section of an inner member, and forcibly nipping and constricting projections of annular fixing bands loosely fitted to said large diameter annular attachment section and said small diameter annular attachment section respectively, said fixing band-tightening apparatus comprising:
- a holding section for gripping said constant velocity universal joint at both ends in an axial direction to rotatably hold said constant velocity universal joint in a circumferential direction in accordance with a driving action of a rotary driving source;
- end-positioning mechanisms provided for said holding section, for positioning said annular attachment sections of said boot made of resin installed to said constant velocity universal joint at predetermined positions before forcibly nipping said projections of said fixing bands;
- and
- a bellows section-pressing mechanism provided for said holding section, for pressing a bellows section of said boot made of resin disposed closely to said small diameter annular attachment section installed to said shaft section of said inner member of said constant velocity universal joint toward said large diameter annular attachment section before forcibly nipping said projection of said fixing band.
