Description

Technical Field

[0001] The utility model relates to the technical field of flywheel processing, in particular to a clamp for processing an engine flywheel. Background Art

[0002] The flywheel is a disc-shaped part with a large moment of inertia, and it acts as an energy storage. 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. Therefore, the torque output by the crankshaft changes periodically, and the crankshaft speed is also unstable. In order to improve this situation, a flywheel is installed at the rear end of the crankshaft.

[0003] However, the existing engine flywheel processing fixture has a weak clamping function. When in use, the flywheel needs to be positioned and fixed during processing. The fixing and installation steps of the existing technology are relatively cumbersome and cannot be adapted to flywheels of different sizes and models. The flywheel is fixed on the processing table by turning the bolts, which makes it inconvenient to take it out during disassembly and assembly. Utility Model Content
