METHOD OF PUTTING CIRCULAR TOROIDAL SPRINGS IN OUTER GROOVES OF WORKPIECES AND A DEVICE FOR PERFORMING IT

A method of putting circular toroidal springs into outer grooves of workpieces, especially in the outer grooves of shaft seals. A circular spring (6) is inserted into a flexible bearing (1), into which a transfer mandrel (2) is inserted, by which means the spring (6) is transferred onto its circumference, the transfer mandrel (2) with the spring (6) is ejected from flexible bearing (1) and moves above the shifting bearing (3), abutting on it, whereupon the spring (6) is transferred by a transfer sliding sleeve (23) from the circumference of the transfer mandrel (2) onto the shifting bearing (3), on which it remains even after the return of the transfer mandrel (2) to its parking position, whereupon the insert mandrel (4) moves above the shifting bearing (3) and abuts on it, whereupon with the aid of the shifting sliding sleeve (34), the spring (6) moves onto the circumference of the insert mandrel (4) which moves with the spring (6) above the insert bearing (5) in which the workpiece (7) is placed, whereby the insert bearing (5) abuts on the workpiece (7), whereupon with the aid of the insert sliding sleeve (44), the spring (6) moves from the circumference of the insert mandrel (4) to the outer groove of the workpiece (7) and the insert mandrel (4) returns to its parking position. In addition, the invention relates to a device for performing this method.
