Detailed description of the invention
With reference to accompanying drawing, the utility model is achieved in that a kind of movable fast-holding head, it comprises the workpiece 3 of locating module 2 and clamp module 1 and clamping, and described locating module 2 is a L-type die holder, and it is made up of horizontal U-shaped seat 21 and vertical positioning head 22 disjunctor; Clamp module 1 comprises a T-shaped die holder 11 and connected movable clamping head 12 forms, and clamp module 1 also comprises interchangeable pressing plate 13 and is fixedly connected with movable clamping head 12.
As shown in Figure 2 and Figure 4, the T-shaped die holder of the utility model 11 and movable clamping head 12, through being flexibly connected with the dovetail groove 121 that T-shaped die holder 11 horizontal bottom inclination angle at 45 ° is arranged, suitably can adjust the upper-lower height of movable clamping head 12 through its dovetail groove; Movable clamping head 12 is provided with the screw hole 122 being parallel to dovetail groove 121 and is equipped with clamping screw 14; Movable clamping head 12 is fixedly connected with T-shaped die holder 11 through clamping screw 14, nut 15; T-shaped die holder 11 is provided with nut bore 16 and is equipped with clamping screw 14, nut 15; Interchangeable pressing plate 13 is fixedly connected with movable clamping head 12 through bolt, for the replaceable pressing plate of workpiece 3 clamping of different materials, guarantees that workpiece 3 can not press from both sides bad, ensures Product Precision.
