Abstract

PURPOSE: To carry a thrusting force to a positioned and clamped workpiece by a collet chuck when machining the workpiece, by driving a lock-up cylinder to contract the collect chuck along a sleeve and holding a piston rod not to move toward the body of a clamping unit.
CONSTITUTION: A positioning bushing 44 and a piston rod 27, which are parallel with a guide bar 15, are secured on one side of the body 17, 17' of a clamping unit, which slides on the guide bar 15. A piston 28 coupled with the piston rod 27 is fitted in a clamping cylinder 29. A collet sleeve 30 and a lock-up cylinder 32 are connected to the clamping cylinder 29. When a workpiece is positioned by the positioning bushing 44 and an insert bushing 23 in a plate 19 for supporting the workpiece, a collet chuck 31 is constracted by the leftward movement of a piston 33 in the lock-up cylinder 32. The piston rod 27 is held not to move toward the body 17 of the clamping unit. When the boss part 4 of the workpiece is drilled, the thrust to the workpiece is carried by the collet chuck 31.
