Detailed Description

Referring to fig. 1 to 4, in an embodiment of the present invention, a workpiece clamping device for a numerically controlled milling machine includes a workbench 1, a workpiece 2 is placed on a top of the workbench 1, and a clamping mechanism 3 contacting the workpiece 2 is disposed on the top of the workbench 1.

Wherein, fixture 3 includes the riser 301 at 1 top of workstation of four fixed connection, the same round bar 302 of fixedly connected with between the adjacent one side of per two risers 301, two round bars 302 all run through two grip blocks 303, and all rotate with two grip blocks 303 and be connected, bar through-hole 304 has all been seted up to two grip blocks 303 one side, equal sliding connection has slide bar 305 in two bar through-holes 304, fixture 3 still includes the first electric putter 307 of fixed mounting on 1 diapire of workstation, first electric putter 307 piston rod end fixedly connected with connecting plate 308, connecting plate 308 top fixedly connected with two lifter 306, two lifter 306 all run through 1 top of workstation, and all with 1 sliding connection of workstation, two lifter 306 tops all are in the outer one end fixed connection of bar through-hole 304 with two slide bars 305.
