Automatically-rotating liquid level alarm performance testing table for liquid storage kettle

Abstract

The invention belongs to the technical field of performance testing of car component sensors, and discloses an automatically-rotating liquid level alarm performance testing table for a liquid storage kettle. The testing table comprises an installation base, a supporting and rotating system, a liquid storage kettle mechanism, a support moving mechanism, a liquid storage kettle clamp, a liquid storage kettle rotation driving mechanism and a control cabinet. The supporting and rotating system comprises a supporting bottom plate, a left rotating connection plate, a right rotating connection plate and an installation table plate. The liquid storage kettle mechanism is fixedly arranged on the installation table plate. Two liquid level alarm performance testing systems for the liquid storage kettle are oppositely arranged on the two sides of the installation base respectively. The support moving mechanism comprises an air cylinder, a guide rail, a guide rail base and a sliding block. The liquid storage kettle is fixedly arranged above the left of a liquid storage kettle fixing plate. When a motor drives the liquid storage kettle mechanism to rotate, a PLC in the control cabinet collects on-off signals of a liquid level sensor and judges whether the alarm performance of the liquid level sensor is qualified. The testing table has the advantages of completing testing at a time, achieving alternating operation of a left station and a right station, improving the work efficiency, carrying out automatic judgment and eliminating misjudgment.

Description

technical field [0001] The invention relates to a liquid level alarm performance tester for a liquid storage pot for automobiles, in particular to a liquid level alarm performance tester for automatic rotation of liquid storage pots for automobiles, and belongs to the technical field of sensor performance testing for automobile parts. Background technique [0002] Usually, the method used to test the liquid level alarm performance of the liquid storage pot for automobiles is: the wire of the liquid level sensor is connected to the light bulb circuit, the mouth of the liquid storage pot faces upwards, and the performance of the liquid level sensor is turned on and the light bulb is on, then the performance is qualified, and the liquid storage pot is manually turned 180° The mouth of the liquid storage pot is facing down, and the liquid level sensor is disconnected and the light bulb is off, then it is qualified. Repeat three times to detect the movement of the float of the liq...
