Title: CLAMPING DEVICE EQUIPPED WITH LIFTING FUNCTION
Abstract:
A cylindrical advancing/retreating member (3) is inserted into a housing (1) so as to be movable in the vertical direction in a sealed manner. The housing (1) is provided with an advancing/retreating mechanism (13) for causing the advancing/retreating member (3) to move in the vertical direction. A support cylinder (17) capable of being inserted in a hole (21) of a workpiece (20) is disposed so as to protrude upward from the advancing/retreating member (3). A pressing surface (4) formed at the top end of the advancing/retreating member (3) is configured to be able to push up the workpiece (20). When the advancing/retreating member (3) is moved upward by the advancing/retreating mechanism (13), the advancing/retreating member (3) causes the support cylinder (17) to be inserted from below into the hole (21) of the workpiece (20), and also pushes the workpiece (20) upward via the pressing surface (4).
