Problems solved by technology

[0003] However, when using the dial indicator device to test the coaxiality, two people need to cooperate to complete it. One person uses the crankshaft and the other observes the dial indicator reading. The operation is complicated and labor-intensive, and the manual reading results in large measurement errors.

Abstract

The invention discloses a flywheel housing coaxiality measuring device which comprises a crankshaft rotating assembly installed on a flywheel housing starting motor installation base and a measuring assembly fixed to a flywheel housing. The crankshaft rotating assembly comprises a driving motor, a connecting base and an output gear, and the driving motor is driven to drive the output gear to rotate so that a crankshaft can rotate synchronously. The measuring assembly comprises a mounting substrate, a sliding block, a sensor frame, a sensor mounting base and a sensor. The measuring device has the advantages that labor intensity is reduced, uniform rotation of the flywheel housing is guaranteed, measuring precision of the measuring assembly is improved, the measuring precision of the measuring device is greatly improved through automatic reading and measurement of the sensor compared with manual observation of a dial indicator, and in addition, due to the fact that the sensor frame can be movably fixed to the sliding block, the measuring assembly can measure the coaxiality of different types of flywheel housings, and the applicability is high.

Description

technical field [0001] The invention relates to the technical field of flywheel housings, in particular to a measuring device for coaxiality of flywheel housings. Background technique [0002] The flywheel housing is an important component of the engine. The coaxiality between the flywheel housing and the crankshaft is an important parameter for engine assembly. Effective monitoring of the coaxiality is the only way to ensure the quality of the engine. For example, the Chinese Utility Model Patent Publication No. CN207923040U discloses a coaxiality checker for the flywheel housing of an engine, which is used to improve the efficiency and accuracy of the detection of the coaxiality of the flywheel housing. At present, most of the existing measurement technologies for the coaxiality between the flywheel housing and the crankshaft are measured by dial indicators. The dial gauge probe is placed on the spigot of the flywheel housing, calibrated to zero, and then the crankshaft i...
