The technical scheme is as follows: the utility model provides a simple and easy anchor clamps that is used for clamping face to be non-planar part, includes base, dog, adjusting bolt, fastening bolt, screw rod, the dog is in the base top, both with adjusting bolt connects, the base is equipped with the spill notch from the upper surface, fastening bolt wears to locate dog and orientation in the notch, from a plurality of directions on the base seted up respectively with communicating screw hole in the notch, the screw rod is worn to locate the screw hole orientation in the notch.
Furthermore, the concave notch is a V-shaped notch and is easy to abut against and position with the surface of the part.
Preferably, the concave notch is an isosceles right triangle with a bottom surface facing the stop block.
Further, the adjusting bolts are respectively arranged on two transverse sides of the concave notch.
Furthermore, a clamping platform is formed on the base, the plane of the clamping platform is lower than the concave notch, and the clamping platform can be used for integrally clamping the clamp on the machine tool and does not interfere with the clamping of the part on the clamp.
Furthermore, the front end of the screw is provided with a flexible cushion block, the rear end of the screw is provided with a limit nut, the flexible cushion block is detachably connected with the screw, the flexible cushion block is located in the concave notch, and the limit nut is located outside the base. When the screw is screwed in and the surface of the part is abutted, the flexible cushion block can keep a good fitting degree with the part, and the nut is abutted and pressed with the base from the rear end of the screw to further fix the part.
Has the advantages that: compared with the prior art, the utility model has the advantages that: the structure that adopts the fixed combination of point face, the fixed combination of multiple spot guarantees that the centre gripping of special-shaped structure part is firm on this anchor clamps, guarantees the centre gripping stability in the course of working, guarantees levelness, straightness that hangs down, can not shift to guarantee the machining dimension precision, improve the processing security performance, this simple and easy anchor clamps commonality is strong, to being processed the condition that the part kind is many, single small in quantity, can self-control in order to reduce manufacturing cost.
