Detailed Description
As shown in fig. 1 and 2: the utility model discloses a five machining center anchor clamps of gas-liquid linkage, including the connection pad 3 that is located the bottom and with connection pad 3 fixed connection's air chuck 4. An annular connecting plate 6 is fixedly connected above the connecting disc 3 through a supporting block 5, and a mounting plate 7 is fixed on the connecting plate 6. The jaws 16 of the air chuck 4 extend upwardly from elongated slots 17 in the mounting plate 7. An airtight supporting plate 8 and an installation seat 18 are fixed at the central part of the installation plate 7, a hydraulic cylinder 13 is vertically fixed at the upper end of the installation seat 18, a connecting seat 19 is fixed at the upper end of the hydraulic cylinder 13, and a connecting head 12 is fixed at the upper end of a piston rod matched with the hydraulic cylinder 13.
