Description

Technical Field

[0001] The utility model relates to fan bearing box production equipment, in particular to a fan bearing box casting overturning device. Background Art

[0002] The fan bearing housing is a part connected to the fan shaft to support and lubricate the bearing. It is a key component of large and medium-sized fan equipment. Its main function is to prevent dust and dissipate heat from the bearing. The fan bearing housing is generally a casting, usually cast using a casting mold. After the fan bearing housing is cast using a casting mold, first open the upper mold, and then use the flip device to flip the lower mold to a certain angle to facilitate the removal of the casting.

[0003] CN 212221577 U discloses a turning device for metal casting, which comprises a workbench; a support plate and an L-shaped plate are provided on the workbench; the support plate is fixedly connected to one side of the upper end surface of the workbench, and a driving unit is provided on the support plate; the lower plate surface of the L-shaped plate is connected to the other side of the upper end surface of the workbench through an adjustment unit, and a driven unit is provided on the L-shaped plate; the driving unit comprises a motor, a No. 1 gear, a No. 2 gear, a No. 1 rotating shaft and a No. 1 receiving plate; the motor is fixedly connected to a side wall of the support plate, a No. 1 gear is sleeved on the output shaft of the motor, the No. 1 gear is meshed with the No. 2 gear, the No. 2 gear is sleeved on one end of the No. 1 rotating shaft, the other end of the No. 1 rotating shaft passes through the support plate and is fixedly connected to the No. 1 receiving plate, and the outer ring of the No. 1 rotating shaft is hinged on the support plate. The driven unit comprises a No. 2 rotating shaft and a No. 2 receiving plate; the No. 2 rotating shaft is hinged on the L-shaped plate, and the end of the No. 2 rotating shaft is fixedly connected to the No. 2 receiving plate. After the casting is cooled into a block, it needs to be taken out of the casting mold and the motor is started. The motor meshes with gear No. 2 through gear No. 1. Gear No. 2 drives receiving plate No. 1 to rotate through the rotating shaft. Receiver plate No. 1 drives receiving plate No. 2 to rotate through the casting mold. Then the upper port of the casting mold gradually faces the workbench. Finally, the casting is separated from the casting mold.

[0004] However, this flipping device has the following problems: it adopts a more common driving structure, that is, it drives the rotating shaft located at the end side of the casting mold to drive the casting mold to flip it. This driving structure causes the rotating shaft to be subjected to very large torque, which can easily cause the rotating shaft to break, posing a major safety hazard. Utility Model Content
