Machining coolant/lubricant is used to operate a piston of a clamping-side coupler by feeding same via a coolant feed passage to a clamping pressure chamber through a first check valve and a clamping pressure fluid passage. The same coolant/lubricant is discharged from an unclamping pressure chamber through an unclamping pressure fluid passage and a second check valve. The resulting movement of the piston downwards brings a clamp member into contact with a workpiece to thereby clamp the workpiece on a table. Thus, a dedicated pressure source for clamping can be dispensed with.

A multiple-bolt insertion tool in accordance with the present invention simultaneously inserts bolts into at least two bolt holes arrayed in a workpiece and includes a bolt receiving member and a hold-and-release mechanism. The bolt receiving member includes bolt positioning portions which establish a positional relationship among the bolts that are to be inserted that matches the positional relationship of the bolt holes, and a tool positioning portion, which fits (mates with) the workpiece to locate the bolt positioning portions in alignment with corresponding bolt holes in the workpiece. The hold-and-release mechanism holds the bolts in the bolt positioning portions until the tool positioning portion is mated with the workpiece and can release the bolts from the bolt positioning portions.
