An automatic centering adjustment system of an engine stand

Abstract

The invention provides an automatic centering adjustment system for an engine stand, comprising a stand base, a laser sensor, a control system and a pressure controller; On the base, the laser sensor is fixed above the shaft of the dynamometer, and the vibration recognition sensor is fixed on the base of the bench. The signal output terminals of the laser sensor and the vibration recognition sensor are connected to the control system, and the output terminal of the control system is connected to the pressure controller. Connection; the control system is used to calculate the position information of the engine relative to the dynamometer according to the information sent by the laser sensor, and send the control signal to the pressure controller. The pressure controller is used to control the three-dimensional translation according to the control signal sent by the control system The mechanism moves to center the engine. The invention can realize the automatic centering of the engine bench, and can be widely used in the field of engine test benches.

Description

technical field [0001] The invention belongs to the field of engine test benches, and in particular relates to an automatic centering adjustment and monitoring system of an engine bench for experiments. Background technique [0002] When traditional car companies and research institutes conduct engine bench experiments, engine alignment is often a headache for the experimenters. When changing different engine experiments, due to the different sizes of the engine bases, the flywheel shaft and dynamometer after the engine is replaced The shafts are not on the same axis, so the engine needs to be centered. In the traditional engine centering, the experimenter uses a dial indicator to determine the position of the end surface of the engine flywheel and the circumferential direction, and then uses a sledgehammer to hit the lower support of the engine to change the position of the engine. Then use a dial gauge to measure the position of the engine flywheel, and change the position...

[0002] When traditional car companies and research institutes conduct engine bench experiments, engine alignment is often a headache for the experimenters. When changing different engine experiments, due to the different sizes of the engine bases, the flywheel shaft and dynamometer after the engine is replaced The shafts are not on the same axis, so the engine needs to be centered. In the traditional engine centering, the experimenter uses a dial indicator to determine the position of the end surface of the engine flywheel and the circumferential direction, and then uses a sledgehammer to hit the lower support of the engine to change the position of the engine. Then use a dial gauge to measure the position of the engine flywheel, and change the position after multiple measurements and sledgehammer knocking until the engine flywheel shaft and the dynamometer shaft are aligned. This method wastes time and increases the labor of the experimenters. manual labor
