Abstract
There is disclosed a chuck jaw (10.1, 10.2, 10.3) for securing a workpiece (12) to a lathe chuck. The chuck jaw (10.1, 10.2, 10.3) includes a jaw body (16) adapted for operative mounting to the lathe chuck. The chuck jaw (10.1, 10.2, 10.3) further includes at least one holding element (18) operatively associated with the jaw body (16) and adapted to engage the workpiece (12). The at least one holding element (18) is moveable between (i) a release condition in which the holding element (18) is released from the workpiece (12), and (ii) an engaged position in which the holding element (18) engages a surface of the workpiece. The chuck jaw (10.1, 10.2, 10.3) further includes a clamping assembly (20) operatively adapted to secure the at least one holding element (18) in the engaged position.
Claims3
A chuck jaw for securing a workpiece to a lathe chuck, the chuck jaw including:
- a jaw body adapted for operative mounting to the lathe chuck;
- at least one holding element operatively associated with the jaw body and adapted to engage the workpiece, the at least one holding element being moveable between (i) a release condition in which the holding element is released from the workpiece, and (ii) an engaged position in which the holding element engages a surface of the workpiece;
- and a clamping assembly operatively adapted to secure the at least one holding element in the engaged position;
- wherein the at least one holding element is a first holding element and the chuck jaw includes a plurality of holding elements each operatively adapted to engage the workpiece;
- wherein each respective holding element is moveable between (i) a release condition in which the respective holding element is released from the workpiece, and (ii) an engaged position in which the respective holding element enrages a surface of the workpiece;
- and wherein each holding element includes a holding element body and two holding element legs outwardly extending for the holding element body;
- wherein the two holding element legs define a holding slot between them;
- wherein the jaw body includes at least one jaw body bore for receiving a fastener to secure the jaw body to the lathe chuck;
- wherein the one jaw body bore is a first jaw body bore and the jaw body includes a second jaw body bore to receive a second fastener to secure the jaw body to the lathe chuck;
- wherein the clamping assembly includes a jaw body clamping member outwardly extending from the jaw body and a clamping element operatively associated with the jaw body clamping member, in use the at least one holding element being clamped between the jaw body clamping member and the clamping element;
- wherein the jaw body clamping member includes a clamping member hole operatively adapted to be located in register with a corresponding clamping element hole of the clamping element;
- wherein the holding slot of the at least one holding element is adapted to permit a clamp fastener to pass through the clamping member hole, through the holding slot and through the corresponding clamping element hole;
- wherein the jaw body clamping member includes a plurality of clamping member holes operatively adapted to be located in register with corresponding clamping element holes of the clamping element;
- wherein the holding slot of each of the plurality of holding elements is adapted to permit a clamp fastener to pass through the clamping member hole, through the holding slot and through the corresponding clamping element;
- wherein the jaw body defines a jaw body guide formation which is operatively adapted to couple with a complemental clamping element guide formation of the clamping element;
- wherein the jaw body guide formation is a jaw body slot and the clamping element guide formation is clamping element adapted to be received and held within the jaw body slot.
