    摘要： A collet assembly includes a collet and a tubular valve sleeve sleeved on a rotary shaft that is disposed within a stationary wall body and which defines a piston-receiving chamber. A piston is disposed movably in the piston-receiving chamber. The valve sleeve is formed with a valve opening therein, a valve chamber extending from the valve opening, a valve inlet in fluid communication with the valve chamber and a fluid injection passage in the stationary wall body, and a valve outlet in fluid communication with the valve chamber and a fluid channel in the shaft. A check valve is mounted in the valve chamber, and is moved to an open position, in which, the valve opening is opened due to injection of a high-pressure hydraulic oil into a clearance through the fluid injection passage, thereby permitting movement of the piston, which, in turn, results in clamping of the collet.

    摘要： Systems and methods include using a pull stud bolt for connecting a tool holder to a collet in a spindle. The pull stud bolt includes a body configured to receive a tool holder, the body having a longitudinal passage fluidly connected to a cavity, the cavity fluidly connected to a plurality of longitudinal channels; a sealing ring disposed around an end of the longitudinal passage, the sealing ring in contact with the cavity; a spring disposed in the cavity; and a sphere in contact with the spring. The sphere is configured to unblock the end of the longitudinal passage by losing contact with the sealing ring when a first force applied to the sphere from the spring is less than a second force applied by a fluid flowing through the longitudinal passage. The first and second forces are substantially opposite in direction of application.

    摘要： A collet adaptor (10) including a body (11, 12) having forward and rear ends and an axial bore (17) extending through the forward and rear ends. A drawbar (13) disposed at least partly within the bore (17) for connection to a collet (14). The drawbar (13) is secured within the bore (17) and a biasing arrangement (42) acts on the drawbar (13) in a direction tending to shift the drawbar (13) rearwardly within the bore (17). The drawbar (13) is displaceable within the bore (17) against the biasing influence of the biasing arrangement (42) to shift forwardly within the bore (17).

    摘要： The present invention relates to a tool holder, in particular a steep-taper shank type tool holder, the tool holder comprising at least one mounting surface, in particular a mounting cone, for being received and driven by a drive spindle, and further comprising at least one integrated fluid path for an operating fluid, wherein at least one flow blocking member is associated with the at least one fluid path and is configured to block or release the at least one fluid path in a manner depending on flow direction. The at least one flow blocking member may be configured and arranged such that it permits flow for the operating fluid in the intended direction of supply and does not permit flow for the operating fluid in opposition to the intended direction of supply. The tool holder may be arranged as a chuck or a clamping chuck, for example.

    摘要： A method and apparatus for controlling an air motor. Speed information is received for an operation using an apparatus comprising the air motor having an inlet and an exhaust, and a valve comprising a body with a first port, a second port, and a third port. The first port is connected to the air motor, the second port is configured for connection to an air supply, and the third port is configured to vent air out of the body. A first flow of air is controlled in the body between the first port and the second port and a second flow of air is controlled out of the body through the third port to control a speed of the operation.
