Technical Field
[0001] The utility model relates to the technical field of flywheel disc processing, in particular to a fixing device for punching holes in a flywheel disc. 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] When processing a flywheel, it is necessary to drill a hole in the middle of one side of the flywheel disc. Traditionally, a dotting tool is used to manually mark the hole before drilling, and then the flywheel disc is rotated in sequence to make the marked position correspond to the drill bit, and the middle of the flywheel disc is drilled. However, this method has poor accuracy and low processing efficiency. Based on this, a fixing device for punching a flywheel disc is proposed to solve the above problems. Utility Model Content

This scheme effectively prevents interference between the mounting bracket and the inner wall of the limit groove. At the same time, the limit groove provides a larger operating space for the mounting bracket, which is convenient for changing the relative position between the flywheel disc and the drilling rig, and facilitating drilling of the flywheel disc by the drilling rig.
