Technical Field

[0001] The utility model relates to the field of machining of crankshaft holes of flywheel housing blanks, and particularly relates to a simple lifting tool for machining crankshaft holes of flywheel housing blanks. Background Art

[0002] The flywheel housing is a core component of the engine. It not only bears the weight and external forces during the operation of the engine, but also ensures the correct position between the engine and the transmission and the smooth transmission of power. In the process of machining the crankshaft holes of the flywheel housing blank, common machining methods include cantilever machining, line boring process machining, and special machine machining, etc. These machining methods all require highly precise equipment and technology to ensure that parameters such as the size, position accuracy, and surface quality of the holes meet the design requirements.

[0003] When machining the flywheel housing, it needs to be suspended. Due to the irregular appearance of the flywheel housing, it is difficult to fix it with traditional lifting tools. Therefore, we need to develop a lifting tool that is suitable for the flywheel housing to facilitate the suspension of the flywheel housing. Summary of the Utility Model
