Detailed Description

An embodiment of the present invention is further described with reference to fig. 1 to 5.

As shown in fig. 1, a machining center anchor clamps, including bottom plate 1, it is connected with a plurality of dwang 9 to rotate on the bottom plate 1, dwang 9 is preferably four, four dwang 9 set up four edges of bottom plate 1 respectively, be equipped with the ascending spout 16 of opening on the dwang 9, it has lifter 3 to peg graft in the spout 16, lifter 3 can move along vertical direction relatively dwang 9, lifter 3's upper end is fixed with the pole 2 that compresses tightly that is used for compressing tightly the work piece, it is connected with connecting rod 4 to rotate on the lifter 3, connecting rod 4 can rotate along the horizontal direction relatively lifter 3, and the in-process that connecting rod 4 reciprocated can drive lifter 3 and reciprocate, the one end that lifter 3 was kept away from to connecting rod 4 with fix the piston rod 6 fixed connection who drives actuating cylinder 8 on bottom plate.

As shown in fig. 3 and 5, the lower side surface of the bottom plate 1 is provided with a mounting groove 12, a rotating device capable of driving all the rotating rods 9 to rotate simultaneously is arranged in the mounting groove 12, the rotating device comprises a driving gear 13 rotatably connected with the bottom surface of the mounting groove 12, the lower end of each rotating rod 9 extends into the mounting groove 12, the lower end of each rotating rod 9 is fixed with a driven gear 11 engaged with the driving gear 13, the rotation of one rotating rod 9 can drive the driven gear 11 on the rotating rod 9 to rotate, the driven gear 11 can drive the driving gear 13 to rotate, at this time, the driving gear 13 can drive other driven gears 11 to rotate together, and finally all the compressing rods 2 are driven to.

As shown in fig. 4, be equipped with along its length direction's spacing groove 5 on the outer wall of lifter 3, threaded connection has the spacing bolt 7 that inserts spacing groove 5 on dwang 9, and the in-process that lifter 3 reciprocated, spacing bolt 7 removed in spacing groove 5, and spacing bolt 7 can avoid lifter 3 relative dwang 9 to take place to rotate.
