Description

The pawl pincers

The utility model belongs to a kind of clamping tool of mechanical processing industry, is suitable for clamping bigger, the complex-shaped workpiece of workpiece, especially size of various sizes, different shape.

Traditional universal fixturing, the chuck of using as lathe, the vice that planer is used are all made an integral body, and have following point in the use: jaw is restricted by base, can not free opening and closing; The jaw direction of motion is single, is difficult to the workpiece of pinch form complexity.

The purpose of this utility model is to overcome the drawback of this traditional common anchor clamps, designs a kind of opening and closing on demand, clamps the pawl pincers of various sizes and complex appearance workpiece from different directions.

The purpose of this utility model is such realization: adopt the motion of freewheel clutch principle Variable roll to design check lock lever for rectilinear motion, by fixed chela and can turn to chela and the check lock lever chela is formed.The base of fixed chela, chela seat, chela, binding clip are an integral body; But can turn to chela to form by base, chela seat, chela, binding clip steering mechanism and angle orientation mechanism; Check lock lever comprises connecting rod, latch segment, locking bed, rolling element composition, and check lock lever and locking bed all can have the angle groove, can not want according to the concrete structure locking bed, and rolling element can be the pure rolling body, cylinder, spherosome, the frustum of a cone.

Because adopt said structure, the utility model is compared with existing clamping tool, because chela clamping work pieces flexibly, not limited by workpiece size and shape, check lock lever connects two parts, its cling properties and is better than existing screw rod, so have novel structure, easy to operate, advantage such as with better function.

Below in conjunction with accompanying drawing in detail embodiment of the present utility model is described in detail.
