Abstract
A latching mechanism for a tool spindle or mandrel that latches by pivotally extending a plurality of tensioned arms from a tensioned seated state to a tensioned locked state through rotation of a lock ring pivotally deploying the arms from their nested seated state into a blade engaging position of a larger radius than the radius of the lock ring with the arms in their nested position.
Claims15
A latching mechanism for mounting tools onto a spindle or mandrel, comprising:
- a substantially cylindrical housing having a flange as a housing base with said housing having fastener mounting means for attaching said housing to a spindle;
- a tool lock ring having bore mounting means for attaching said lock ring onto said housing with said lock ring having a plurality of deployable tensioned pivotal arms provided as latching means for holding a tool attachment between said flange and said deployable tensioned pivotal arms of said lock ring with said lock ring having an initial radius when said deployable tensioned pivoted arms are in a subjacent position;
- and
- a pivotal arm retainer for holding said deployable tensioned pivotal arms in said subjacent position and returning said deployable tensioned pivotal arms from a blade engaging deployed position to said subjacent position via rotation of said lock ring for pivotally deploying, and subsequently returning, said deployable tensioned pivotal arms from said subjacent position into said blade engaging deployed position of a larger radius than said initial radius of said lock ring when said deployable tensioned pivotal arms are in said subjacent position.

A latching system for mounting tools onto a spindle or mandrel, comprising:
- a spindle mount member having threaded bore, spindle mount flange and cylindrical body having a cavity receiving a fastener;
- a substantially cylindrical housing having a flange as housing base with said housing having a bore for mounting onto said spindle mount member and an exterior wall fastener extendable into the spindle mount cavity;
- a lock ring having bore mounting means for attachment onto said housing with said lock ring having a plurality of deployable pivotal arms provided as latching means for holding a tool between said flange of said housing and said deployable pivotal arms of said lock ring with said lock ring having an initial radius when said deployable tensioned pivoted arms are in a subjacent position;
- and,
- a pivotal arm retainer for holding said deployable pivotal arms in a lock ring subjacent position and returning said deployable pivotal arms from a bladed engaging deployed position to said subjacent position via rotation of said lock ring for pivotally deploying, and subsequently returning, said deployable tensioned pivotal arms from said
- subjacent position into said blade engaging deployed position of a larger radius than said initial radius of said lock ring when said deployable tensioned pivotal arms are in said subjacent position.
