Abstract
The invention discloses a device for preventing a positional deviation of a long hole of a bearing bush. The device comprises an ejection block (1), a spring (2) and a guide rod (3). The ejection block adopted by the device is provided with push arms, a carrying plate and a guide hole. The spring is a cylindrical spiral compression spring. The guide rod is a hexagon socket cylindrical-head bolt. The ejection block is arranged on the right portion of a lower die, and the guide rod penetrates through the carrying plate in a sliding mode through the guide hole. The guide rod is fixedly connected with the right side face of a lower die plate of the lower die. The guide rod is sleeved with the spring, and the spring is located between the cylindrical head of the guide rod and the right side face of the carrying plate. The pushing arms are located between the upper surface of the lower die plate and the lower surface of a die anvil in a sliding mode. According to the technical scheme, during work, a bearing bush workpiece is suspended by the push arms and an upper positioning post of the die anvil, the lower surface of the bearing bush workpiece makes no contact with the upper surface of the die anvil, a suspension gap is formed between the lower surface of the bearing bush workpiece and the upper surface of the die anvil, and the bearing bush workpiece is made to rotationally slide on the die anvil by stopping vibration during downward punching of an upper die under the suspension effect, so that the purposes of achieving good consistency, eliminating waste products and reducing cost are realized in the production process of the long hole of the bearing bush.
