Embodiment 1
[0027] A tool for measuring the center of mass of an engine, the tool includes a 12mm thick steel plate 7, a bracket 5 with two rollers 6, and the two rollers 6 are connected by an iron rod with a diameter of 25mm to ensure that the two wheels are parallel to the engine 4 and on the same plane superior. The roller 6 bracket is located on the steel plate, and the roller bracket 5 is used to support the engine to be tested. There is a tooling hook 1 on the other side of the engine to be tested. Connect the engine. The center of mass measurement tools include a plumb, a straightedge and a level; when measuring the center of mass of a machine part, the plumb is used to measure verticality, the ruler is used to measure distance, and the level is used to measure levelness.

The invention relates to a center-of-mass measuring tool of an engine, belonging to the technical field of measurement of the engine. The invention is characterized in that the center-of-mass measuring tool comprises a flat plate, a bracket with two rollers which are connected by a shaft, a tooling lifting hook and a weighing tensioner, wherein the bracket with two rollers is positioned on the flat plate and is used for bearing a center-of-mass machine part to be measured; and the other side of the center-of-mass machine part to be measured is provided with the tooling lifting hook which is connected with the weighing tensioner. The center-of-mass measuring tool has the advantages of having simple structure and low fault rate, saving cost, labor and measuring time, being economical and practical and having accurate measurement and easy popularization.
Description
technical field [0001] The invention belongs to the technical field of engine measurement, in particular to an engine mass center measurement tool. Background technique [0002] At present, with the rapid development of my country's automobile industry, the application matching work of its key component engine is becoming more and more important. In order to make the engine better match the vehicle, it is necessary to provide the engine's Center of mass position, because the engine mass center position parameter is a prerequisite for measuring the moment of inertia and is a necessary parameter for the engine dynamic model, which is of great significance to the analysis of engine dynamic characteristics and the vibration isolation design of the mount. [0003] The position of the center of mass of a regular object can be obtained by calculation, but for a complex and irregular object like an engine, the calculation is quite troublesome, and because most of the parts of the eng...
