Abstract
The invention discloses a drilling and positioning fixture with balance clamping force function, including: a base, a vertical plate, the first positioning part, the second positioning part, a clamping mechanism and a balancing mechanism. By locating pillar and the clamping jaw, the lower end surface of the workpiece is closely attached to the mating surface of the base, and maintain a relatively constant position. The horizontal state of the workpiece is adjusted by the top rod, so that the processed horizontal holes and vertical holes have a higher perpendicularity, which can meet the requirements of the assembly process. In that invention, by the fit of balancing plate, the first and the second positioning part, when adjusting any nut, the clamping claw on both sides of the base can always keep the abutment force of the workpiece by the micro rotation of the balance plate, therefore effectively prevent the workpiece from being deformed due to uneven clamping force, improving the machining accuracy of the workpiece.
