这种机械手与自动线的托盘配合,利用卡爪使工件定位,如图所示。淄板上装有卡爪,通过连杆与气缸相连。卡爪在后端时,由于弹簧作用,卡爪成张开状态,并随着气缸杆向前伸出。当淄板触及限位挡铁后。停止前进,活塞杆继续外伸,使爪部收拢,夹紧工件并使其定位。当活塞杆后退时,由于弹簧的作用,卡爪张开,放开工件;活塞杆继续缩回,带动淄板一并后退复位。 本机构用于气缸实现前进、后退和夹紧、放松动作。
This robot with automatic line tray with the use of claws to position the workpiece, as shown. Ziban equipped with claws, connecting rod through the cylinder. When the pawl is at the rear end, due to the action of the spring, the claw is opened and extends forwardly with the cylinder rod. When the limit plate Zibo accession iron. Stop forward, the piston rod continues to stretch, so claw folded, clamping the workpiece and positioning. When the piston rod back, due to the role of the spring, the jaw open, let go of the workpiece; piston rod continued to retract, Zidong together drive back to reset. The mechanism for the cylinder forward, back and clamp, relax action.
