摘要： A primary piston (19) slides axially on a spindle body (5). Together with two cylindrical bearing surfaces of different diameters (D1 and D2) of the spindle body, the primary piston bounds a primary hydraulic chamber 22) which communicates via a conduit (25) with a secondary hydraulic chamber (24). The active face (33) of a secondary piston (20) bounds the secondary hydraulic chamber (24), so that the secondary piston (20) is displaced in response to a displacement of the primary piston (19) which is reduced in the same ratio as the cross-sections of the two chambers. The secondary piston (20) acts upon a chucking sleeve (15) which actuates the chuck (12) against the bias of a spring member (17) which, in the absence of pressure, holds the chuck (12) grippingly on a workpiece. The primary piston (19) is controlled by compressed air fed through a fixed spindle support (1) via a conduit (27) into a pneumatic chamber (21) bounded by a fixed bore (8) and by two disk-shaped elements (7 and 19) rotating with the spindle.

摘要： A hydraulic chuck having a piston means with an axially centered passage and a first end sized to engage a tube. Collet means are located at the first end of the piston for engagement with said tube upon closure of the collet means. Surface means bearing on the collet means are provided to close the collet on the tube. Biasing means are provided to normally force the surface means against the collet means to incur a normally closed position of the collet. A handle or attachment means is provided for movement of the biasing means to remove the surface means from the collet means whereby the tube may be inserted into the chuck. Finally, passage defining means in the piston means are provided to force the surface means onto the collet means when fluid is passed through the axially centered passage.

摘要： A machine tool spindle characterized by excellent dynamic balance at very high rates of rotation and adapted for automatic tool changing has a tool-holding collet actuated by a plunger coaxial with the spindle. The plunger is maintained in the toolholding position by belleville springs that rotate with the plunger and collet and a nonrotating push rod engages the plunger and drives it against the spring bias to open the collet when a tool is to be released or picked up. Advantageous embodiments of the invention, the collet draws air through a small conduit in the spindle, thereby cleaning dust from the collet fixture.

摘要： An indexable tool turret for use in a machine tool having an automatic tool changer. The turret has two tool stations, both of which have a motor operated clamp for securing a tool in the station with a locating surface of the tool clamped against a locating surface of the turret. Each station has a plurality of air jets directed at the tool when it is inserted into the station so that dirt and debris are blown clear of the tool and particularly its locating surfaces automatically as the tool is inserted into the station. Indexing of the turret is effected by lifting the tool turret clear of a gear coupling and rotating the turret to a new index position after which it is lowered to reengage the gear coupling. A hydraulic motor raises and lowers the turret and functions as a relatively friction free hydraulic thrust bearing to support the turret in the raised position while it is indexed.
