Description

Technical Field

[0001] The utility model relates to the technical field of flywheel processing assistance, in particular to a flywheel dynamic balance testing tool. Background Art

[0002] The main function of the flywheel is to store energy and inertia outside the power stroke of the engine. In a four-stroke engine, only the energy for the power stroke (intake, compression, and exhaust) comes from the energy stored in the flywheel.

[0003] After the flywheel is produced, it must undergo rigorous inspection, mainly for the flywheel dynamic balance test. The flywheel dynamic balance detection device is easily affected by the vibration force generated by the outside world during operation, which will cause a certain deviation in the test result.

[0004] The prior art patent document with publication number CN 206920079 U provides a flywheel dynamic balancing detection workbench, which relates to the field of flywheel processing auxiliary equipment, and particularly to a workbench body, wherein a rotating seat is provided on the workbench body, and a protective baffle and a flywheel placement frame are also provided on the workbench body, wherein the rotating seat is arranged in the protective baffle, and a plurality of partitions are provided in the flywheel placement frame, wherein the protective baffle is detachably connected to the workbench body, and slide rails are provided on both sides of the protective baffle, and a limit block is provided at one end of the slide rail, and the flywheel placement frame is slidably connected to the slide rail, and a limit plate is provided on the side wall at one end of the flywheel placement frame, and the limit plate is rotatably connected to the side wall of the flywheel placement frame through an axis. This design has reasonable structure, is easy to clean, has diverse functions, is convenient to use, and improves work efficiency.

[0005] The above technology facilitates cleaning by setting a protective baffle, but it is easily affected by external vibrations during operation, which may cause movement deviation of the detection structure. Therefore, we need a flywheel dynamic balancing test fixture. Utility Model Content
