摘要： A collet adapter operates a draw-type collet in an axially stationary mode in a machine spindle that would otherwise operate with a stationary collet. The machine spindle has an axially stationary outer portion including a cap nut and an axially movable sleeve inside the axially stationary portion. The collet adapter includes an adapter body and a restraining apparatus. The adapter body has an inside surface that receives the draw-type collet in sliding engagement. The restraining apparatus is configured to transmit an axial force from the stationary cap nut to a rearward portion of the draw-type collet to restrain axial motion of the draw-type collet. As a result of this axial constraint forward and backward motion of the axially movable sleeve closes and opens the collet respectively through the sliding engagement between the collet and the inside surface of the adapter body.

The machine spindle has an axially stationary outer portion including a cap nut and an axially movable sleeve inside the axially stationary portion. The collet adapter includes an adapter body and a restraining apparatus. The adapter body has an outside surface that fits into the axially movable sleeve such that adapter body moves axially with the axially movable sleeve. The adapter body has an inside surface that receives the draw-type collet in sliding engagement. The restraining apparatus is configured to transmit an axial force from the stationary cap nut to a rearward portion of the draw-type collet to restrain axial motion of the draw-type collet. As a result of this axial constraint forward and backward motion of the axially movable sleeve closes and opens the collet respectively through the sliding engagement between the collet and the inside surface of the adapter body.

摘要： A mounting tool for a hydromechanical chuck or mandrel of the type which is clamp connected using a pressure medium in order to clamp connecting a shaft or a shaft tool or a working piece, and in which said shaft or working piece is dismantled from the chuck, and which chuck using a pressure medium in the opposite direction , and which chuck is formed with two separate pressure chambers, a first chamber acting as a clamp connection chamber, and a second chamber acting as a dismantling chamber, which chambers are formed with inlets/outlets provided on opposite sides of the chuck and opening at the periphery thereof. The mounting tool is formed as a yoke (2) adapted to stridingly engage the chuck or mandrel to be actuated, said yoke having a first leg (4) formed with a fixed nozzle (8) and the second leg (5) formed with an axially displaceable nozzle (9), both nozzles adapted to engage the two opposite inlets/outlets of the chuck to be activated, and each leg (4, 5) formed with a passageway (6, 7) for directing pressure medium into and out of the nozzle (8, 9). The yoke (2) is substantially U-shaped having the legs thereof (4, 5) so widely spaced as to be able to engage differently wide chucks.

摘要： Le piston primaire (19) coulisse axialement sur le corps de broche (5). Il limite avec les deux portées de diamètre (D1) et (D2) du corps de broche la chambre hydraulique primaire (22) qui est en communication par le conduit (25) avec la chambre hydraulique secondaire (24). La face active (33) du piston secondaire (20) limite la chambre (24) de sorte que le piston secondaire (20) est déplacé en réponse à un déplacement du piston primaire (19) avec un chemin qui est réduit dans le rapport des sections des deux chambres. Le piston secondaire (20) agit sur le manchon de serrage (15) qui actionne la pince (12) contre l'action de l'organe élastique (17) qui en l'absence de pression maintient la pince (12) serrée sur une pièce à usiner. Le piston primaire (19) est commandé par une alimentation d'air comprimé arrivant à travers le support de broche fixe (1) par le conduit (27) dans la chambre pneumatique (21) qui est limitée par l'alésage (8) fixe et par les deux éléments en forme de disque (7) et (19), lesquels tournent avec la broche.
