The utility model relates to a bearing embedding and positioning device for a lower crank case. The bearing embedding and positioning device is used for enabling bearing inserting pieces, used for bearing a journal of the crank case, in a crank case die-casting die to be located at the correct positions, and comprises a framework, actuators, crank jaw parts, a positioning part and a separation device. A rectangular plate is arranged on one side of the formwork, the formwork is provided with a bearing plate, and a quadrangle through hole is formed in the bearing plate. The crank jaw parts extend towards the outer portion of the bearing plate through the quadrangle through hole, and lift the bearing inserting pieces to be lifted when the actuators are started after power is transmitted to the actuators. The positioning part is assembled on the bearing plate, and enables crank jaws to arrange the bearing inserting pieces to the correct positions when the crank jaw parts lift the bearing inserting pieces. The separation device enables the bearing inserting pieces to be separated from the crank jaw parts after the bearing inserting pieces are arranged in the die by the crank jaw parts. According to the bearing embedding and positioning device for the lower crank case, the bearing inserting pieces are simultaneously lifted and accurately placed into the die, operating speed is high, the arranging precision of the bearing inserting pieces is high, and reliability is provided. |
