Described self locating device includes that flexible block, back-moving spring, the regulation screw of supporting, flexible supporting are provided with right angle below the block left side Step, right angle step is arranged above with pointed projection, and profile on the right of block of stretching is mated with arc groove, and centre position is provided with kidney-shaped Hole, mounting hole axis direction is consistent with arc groove axis direction;It is provided with back-moving spring below the flexible mounting hole supporting block, regulates spiral shell Follow closely to mate with the internal thread hole being arranged on locating slot through mounting hole and back-moving spring and be connected in frock main body, back-moving spring It is set on regulation screw;
Described clamping device includes compact heap, clamping sleeve, tightens up block, and described compact heap is strip, the most self-align dress The position of the regulation screw put is fixing connects clamping sleeve, is provided with pivot pin in the middle of compact heap length direction, and pivot pin is hinged to be tightened up on block End;Tightening up block is the plate that lower section is provided with kidney slot, the rolling that in kidney slot, the eccentric handwheel cylindrical of matching tooling main body both sides is installed Dynamic bearing outer ring.
The described flexible block that supports is " axe " shape pressing plate.
Described flexible block and the arc groove mating part of supporting is the least big cone above.
This utility model is rational in infrastructure simply, it is easy, easy to use to manufacture, by this utility model, during use, and institute State the fixture plane using Milling Process as positioning datum so that processing dimension is guaranteed, when block part length occurs by mistake During difference, the cone on the right of block that stretches adjusts in arc groove automatically, during compressing, automatically ensures with block part Milling Process plane positioning, described clamp-replacing workpiece is quick, and the installation workpiece time is greatly shortened, accurate positioning, production efficiency Improve.This utility model energy quickly multiple block part of clamped one time, application block part needs the one side of processing as determining The frock clamp of position reference design, it is possible to make processing dimension reach consistent, effectively solve the deficiency in above frock clamp The defect caused;This utility model positions, fixes quickly, effectively ensures quality, reduces cost, significantly improves production effect Rate.
