Problems solved by technology
When the engine and the dynamometer are manually connected, the coaxiality of the two connection points is not easy to accurately judge, and it is easy to have deviations, which will cause the body to vibrate violently and cause damage to the equipment
Traditional detection methods, such as the fixed-point detection method of the dial indicator, need to use the dial indicator to conduct point analysis at different positions of the engine flywheel, and then determine whether the dynamometer and the engine are coaxially connected after multiple comparisons, which is time-consuming and labor-intensive. very careful sampling

The invention discloses a center calibration device for engine vibration experiment, and belongs to the field of automobile parts detection tooling. The center calibration device comprises a connecting disk, and further comprises a fixing bracket, a screw and a detection pin which are sequentially arranged. The connecting disk is made of a circular plate, and the middle of the connecting disk is provided with four bracket fixing holes distributed in a rectangular shape. The fixing bracket is fixed to the connecting disk through nuts and bolts, and comprises a threaded casing, support arms and fixing plates, which are sequentially arranged from top to bottom. The screw is mounted in the threaded casing, and a pointer sliding rod is fixed at one end of the screw along the radial direction. The detection pin is 'Z'-shaped, and the tail of the detection pin is vertically connected with a sliding sleeve. The center calibration device for engine vibration experiment is skillful in manufacture, low in production cost and high in parts interchangeability. The labor is saved, the cost of engine experiment is effectively reduced, and the time for experiment preparation is shortened.
Description
technical field [0001] The invention belongs to the field of testing tooling for auto parts, and more specifically relates to a central calibration device for engine vibration experiments. Background technique [0002] With the development of the automobile industry, the research and development of new engine models and new technologies have also received extensive attention and attention. In order to verify new models or new technologies, most engine manufacturers have introduced dynamometers and supporting control devices to perform various simulation operations on the engine test bench and test the output power of the engine. When the engine and the dynamometer are manually connected, the coaxiality of the two connection points is not easy to accurately judge, and it is easy to have deviations, which will cause the body to vibrate violently and cause damage to the equipment. Traditional detection methods, such as the fixed-point detection method of the dial indicator, ne...
