Finally, the positive adjustment member 47 is threaded through the stepped slot 414 to the slide block 45.
The clamping process of the clamping device 100 is as follows:
first, the workpiece 300 is placed on the table 20.
Then, the clamping unit 40 is slid in from the end of the mounting groove 23 until the clamping jaw 4323 contacts the workpiece 300.
Thereafter, the forward adjuster 47 is tightened to securely mount the fixed clamp 41 on the table 20.
Finally, the lateral adjustment member 44 is threaded through the tightening stepped bore 4343 and the locking threaded bore 412, and as the lateral adjustment member 44 is progressively tightened, the first movable clamping portion 432 is moved toward the workpiece 300 until the blank is clamped.
According to the clamping device 100 and the clamping device provided with the same, the clamping unit 40 can selectively clamp the workpiece 300 in the forward direction or in the lateral direction, when the workpiece 300 is clamped in the lateral direction, the interference with a machining path of a tool is avoided, and the workpiece does not need to move in the machining process, so that the machining efficiency is high, and the machining quality is good.
