Description

Technical Field

[0001] The utility model relates to the technical field of flywheel pinning presses, in particular to a special press for flywheel pinning with gas-liquid boosting. Background Art

[0002] The flywheel is a disc-shaped part with a large moment of inertia, and it acts like an energy storage device. For a four-stroke engine, work is done once every four piston strokes, that is, only the power stroke does work, while the exhaust, intake and compression strokes all consume work. When installing the flywheel, the sub-pin needs to be installed in the pin hole on the flywheel through a press.

[0003] The existing special press for gas-liquid booster flywheel pin pressing is usually composed of only a gas-liquid booster bar, a workbench and a limit device, and lacks a fixing device for the flywheel. Although the limit device can limit the flywheel, due to the large number of flywheel models and the different sizes of flywheels of different models, the practical effect of the limit device is poor and it is difficult to adapt to flywheels of different models. In addition, since the pin is usually interference fit with the pin hole, the traditional press needs to be manually adjusted when in use, and then the end of the pin is pressed into the pin hole partially, the pin is released, and then the press is completely pressed in by the press. The safety is poor and it is easy to cause damage to the operator's hands. Therefore, the existing special press for gas-liquid booster flywheel pin pressing has the disadvantages of poor adaptability and inconvenience in adjusting the pin. Utility Model Content
