summary of the invention.
For the defect that above-mentioned prior art exists, the purpose of this utility model is to provide a kind of clamping work pieces to stablize, and can protect the rotation clamping device of workpiece to be clamped.
For achieving the above object, the technical solution of the utility model is: rotate clamping device, comprise frame, force arm, left and right pressing plate and transmission mechanism, described left and right pressing plate is positioned opposite, and respective middle part and frame hinged, wherein, described left and right pressing plate bottom is equipped with rotational pin, described force arm is positioned at the centre position of left and right pressing plate, is respectively equipped with transmission mechanism between force arm and left and right pressing plate; Described transmission mechanism comprises handler, transmission arm, screw rod and flexible floating structure, coaxially fix in the middle part of described force arm one end and handler, and be connected with gantry rotation, handler one end and transmission arm one end hinged, the transmission arm other end is connected with screw rod, and described screw rod vertically runs through rotational pin, and screw rod end is provided with anti-drop block, described floating structure is sheathed on screw rod, and one end and rotational pin offset, and the other end and transmission arm offset.
When adopting technique scheme, transmission mechanism is respectively equipped with between force arm and left and right pressing plate, when pulling force arm, handler rotates around middle part, transmission arm hinged with it is outwards strutted, because transmission arm is connected with one end screw rod, screw rod vertically runs through rotational pin, and be provided with relocation mechanism between rotational pin and transmission arm, transmission arm struts and drives floating structure to extrude rotational pin, and screw rod vertical rotation bearing pin is to also sliding in contrast, hinged with frame in the middle part of pressing plate, now left and right pressing plate all rotates around respective pin joint, and realizes the action of clamping work pieces.The utility model drives platen clamp workpiece by having flexible floating structure completely, when the position that workpiece is placed is slightly inclined, can regulate the position of workpiece, stablized by the workpiece clamped, in addition, adopt flexible floating structure to transmit clamping force, during clamping work pieces, clamping force is relatively little, is convenient to clamp yielding workpiece.
Further, described floating structure comprises stage clip and the bar shaped push-plate in " recessed " font, stage clip one end and push-plate closed side offset, the stage clip other end and transmission arm offset, the uncovered width of described push-plate open-position-side is less than the diameter of rotational pin, two flanges of the bar shaped push-plate open-position-side in " recessed " font offset with rotational pin respectively, and the wearing and tearing of rotational pin are less.
Further, described floating structure is butterfly spring, and described butterfly spring, between rotational pin and transmission arm, adopts butterfly spring structure simple, and can provide larger elastic force, be convenient to holding workpiece.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail:
Fig. 1 is the structural representation that the utility model rotates clamping device embodiment;
Fig. 2 is the structural representation that the utility model rotates left pressing plate or right pressing plate and floating structure coupling part in clamping device embodiment 1;
Fig. 3 is the structural representation that the utility model rotates left pressing plate or right pressing plate and floating structure coupling part in clamping device embodiment 1.
Detailed description of the invention
Embodiment 1
As shown in Figure 1, a kind of rotation clamping device, comprise frame, force arm 1, left and right pressing plate 9 and transmission mechanism, left and right pressing plate 9 is positioned opposite, and respective middle part and frame hinged, wherein, left and right pressing plate 9 bottom is equipped with rotational pin 7, force arm 1 is positioned at the centre position of left and right pressing plate 9, is respectively equipped with transmission mechanism between force arm 1 and left and right pressing plate 9; Transmission mechanism comprises handler 2, transmission arm 3, screw rod 4 and floating structure, coaxially fix in the middle part of force arm 1 one end and handler 2, and be connected with gantry rotation, handler 2 one end and transmission arm 3 one end hinged, transmission arm 3 other end is connected with screw rod 4, and screw rod 4 vertically runs through rotational pin 7, and screw rod 4 end is provided with anti-drop block 8, floating structure is sheathed on screw rod 4, and one end and rotational pin 7 offset, and the other end and transmission arm 3 offset.
As shown in Figure 2 and Figure 3, floating structure comprises stage clip 5 and the bar shaped push-plate 6 in " recessed " font, stage clip 5 one end and push-plate 6 closed side offset, stage clip 5 other end and transmission arm 3 offset, the uncovered width of push-plate 6 open-position-side is less than the diameter of rotational pin 7, two flanges of bar shaped push-plate 6 open-position-side in " recessed " font offset with rotational pin 7 respectively, and the wearing and tearing of rotational pin 7 are less.
