The specific embodiment
In order further to explain the technical solution of the utility model, the utility model is elaborated below by specific embodiment.
As shown in Figures 1 to 3, two-way linkage clamping device of the present utility model comprises the first locating piece 1, two-way linkage anchor clamps 2 and driving mechanism 3.
The first locating piece 1 is arranged on the workbench 1b, and the first locating piece 1 is mainly used in preventing workpiece 1a play on workbench 1b.
Two-way linkage anchor clamps 2 comprise body 21 and are articulated in jig arm 22 on the body 21, and jig arm 22 is folding arm structure, forms corner part 23 in the bending place, and the both ends of jig arm 22 are protruded respectively and formed the clamping part 24 that is resisted against on adjacent two outer surfaces of workpiece.
As a preferred embodiment of the present utility model, corner part 23 is hinged by bearing pin and body 21.In addition, the profile of the shape of jig arm 22 and workpiece 1a is roughly coincide, for example, workpiece 1a is rectangle, square structure on the whole, jig arm 22 is folding arm structure at right angles, workpiece 1a is polygonized structure on the whole, and jig arm 22 can match with the profile of workpiece 1a, correspondingly is acute angle folding arm structure or obtuse angle folding arm structure.Like this, two clamping parts 24 of jig arm 22 are resisted against respectively on adjacent two outer surfaces of workpiece 1a, and workpiece 1a is resisted against on the first locating piece 1 and the workbench 1b tightly.
