Abstract
A seal assembly for a toolholder with a collet clamping member having a forcing ring in which at least in part the clamping member can be positioned, and a seal ring with a tool insertion opening including a surrounding O-ring holder that can be removably engaged with the forcing ring to place this seal ring in a selected position therein. An O-ring is provided in the seal ring O-ring holder.
Claims11
A seal assembly for a toolbolder having a clamp member with clamping structures positioned about an extended tool placement opening therein such that said clamping structures can be forced radially inward a selected distance from a selected initial position, said seal assembly comprising:
- a forcing ring extending about a clamping structures opening in which at least in part said clamping structures can be positioned, and also extending about a seal ring opening positioned adjacent to, and coaxially with, said clamping structures opening but separated therefrom by a shoulder structure in said forcing ring extending about a shoulder opening therein positioned coaxially with said clamping structures and seal ring openings though smaller than said seal ring opening, said forcing ring having therein a forcing ring engager accommodation about said seal ring opening;
- a seal ring extending about a tool insertion opening therein including an O-ring holder surrounding said tool insertion opening, said seal ring having therein a seal ring engager provided thereabout across from said O-ring holder such that said seal ring engager, without having to reposition said forcing ring, can be removably engaged with said forcing ring engager accommodation in said forcing ring seal ring opening to place said seal ring in a selected axial position therein including positioned against said shoulder structure;
- and
- an O-ring positioned in said seal ring O-ring holder about said seal ring tool insertion opening.
A seal assembly for a toolholder having a clamping means such that said clamping means can be forced radially inward against a selected tool, said seal assembly comprising:
- a nut means extending about a clamping opening, in which at least in part said clamping means can be positioned, and also extending about a seal ring opening separated from said clamping opening by a shoulder means in said nut means with said nut means having a nut engager means provided about said seal ring opening;
- a seal ring means extending about a tool insertion opening therein including an O-ring holder means surrounding said tool insertion opening, said seal ring means having a seal ring engager means, without having to reposition said nut means, can be removably engaged with said nut engager means in said nut seal ring opening to place said seal ring means in a selected position therein including positioned against said shoulder means;
- and
- a flexible O-ring means positioned in said seal ring O-ring holder means about said seal ring tool insertion opening.
A seal assembly for a toolholder having a collet chuck, said seal assembly comprising:
- a collet nut extending about a collet opening in which at least in part said collet can be positioned, and also extending about a seal ring opening positioned adjacent to, and coaxially with, said collet opening but separated therefrom by a shoulder in said collet nut extending about a shoulder opening coaxial with said collet and seal ring opening though smaller than said seal ring opening, said collet nut having a threaded surface about said seal ring opening;
- a seal ring extending about a tool insertion opening therein including an O-ring holder surrounding said tool insertion opening, said seal ring having a threaded outer surface such that said seal ring, without having to reposition said collet nut, can be removably threaded into sail collet nut seal ring opening to place said seal ring in a selected position therein including against said shoulder;
- and
- an O-ring positioned in said seal ring O-ring holder about said seal ring toot insertion opening.
