Description

Technical Field

[0001] The utility model relates to the technical field of flywheel threaded hole detection devices, in particular to a flywheel threaded hole detection device. Background Art

[0002] A flywheel, a disc-shaped component with a large moment of inertia, acts as an energy storage device. In a four-stroke engine, work is performed only during the power stroke, while the exhaust, intake, and compression strokes all consume energy. Consequently, the torque output by the crankshaft varies periodically, and the crankshaft speed is unstable. To improve this situation, a flywheel is installed at the rear end of the crankshaft, at the power output end of the crankshaft, where it connects to the gearbox and the power generating equipment. The flywheel's primary function is to store energy and inertia outside the engine's power stroke. In a four-stroke engine, only the power stroke—intake, compression, and exhaust—is generated by the energy stored in the flywheel. The flywheel has a large moment of inertia. Because the work performed by each cylinder is discontinuous, the engine speed also varies. As the engine speed increases, the flywheel's kinetic energy increases, storing energy; as the engine speed decreases, the flywheel's kinetic energy decreases, releasing energy. Flywheels can be used to reduce speed fluctuations during engine operation.

[0003] At present, the flywheel threaded hole detection device in the prior art usually lays the flywheel to be tested flat first, stacks the inspection fixture seat on the flywheel, and passes the inspection piece I and inspection piece II through the inspection hole I and inspection hole II respectively, and then inserts them into the threaded hole and positioning pin hole of the flywheel to be tested. The entire movable inspection piece group can complete the insertion operation at the same time, which proves that the flywheel to be tested is a qualified part. However, during the detection process, since the existing inspection method is that the operator manually uses the inspection fixture to detect the bolt hole position accuracy of the flywheel, when replacing different flywheels during the inspection, it is necessary to repeatedly calibrate the center hole of the flywheel with the position of the inspection fixture. Moreover, the inspection fixture is often made of metal, and workers will cause muscle strain after long-term use. Therefore, there is a problem of repeatedly needing to calibrate the center hole of the flywheel with the inspection fixture. In addition, during use, the inspection fixture on the existing inspection device is generally installed by bolts, which makes it inconvenient to disassemble when replacing the inspection fixture, thereby reducing the inspection fixture replacement efficiency. Therefore, there is a problem of inconvenience in replacing the inspection fixture. In summary, the utility model has the problem of repeatedly needing to calibrate the center hole of the flywheel with the inspection fixture and the inconvenience of replacing the inspection fixture.
