It is described in the utility model a kind of for detecting the experimental rig of crankshaft position sensor, including being used for described in fixation
First mounting base of crankshaft position sensor further includes the second mounting base, is fixed with electromagnetic core in second mounting base, institute
It states one end of electromagnetic core and the measuring surface of crankshaft position sensor is oppositely arranged, electromagnetic coil is wound on the electromagnetic core,
The electromagnetic coil is connected in series by conducting wire and switch, AC power and frequency converter；First mounting base and the second installation
Seat is fixed on sweat box or vibration mechine.
Further, the distance between measuring surface of one end of the electromagnetic core face measuring surface and crankshaft position sensor
For 0.2 ~ 3mm.
Further, the distance between measuring surface of one end of the electromagnetic core face measuring surface and crankshaft position sensor
For 2 ~ 3mm.
The beneficial effects of the utility model are：
It, being capable of real simulation signal panels by setting electromagnet on the correspondence position of the measuring surface of crankshaft position sensor
It, can be to crankshaft position sensor in high/low temperature or vibration test to the reaction magnetic of crankshaft position sensor under different rotating speeds
Under the conditions of carry out signal detection when working, and simple in structure, manufacture is at low cost, easy to operate, reliable.
Description of the drawings
Fig. 1 is the structure diagram of the utility model.
In figure, 1-crankshaft position sensor, 11-measuring surface, the 2-the first mounting base, 3-electromagnetic core, the 4-the second peace
Fill seat, 5-electromagnetic coil, 6-switch, 7-AC power, 8-frequency converter.
Specific embodiment
It elaborates below in conjunction with the accompanying drawings to the utility model.
Referring to Fig. 1, shown is a kind of for detecting the experimental rig of crankshaft position sensor, including being used to fix the song
First mounting base 2 of shaft position sensor 1 further includes the second mounting base 4, electromagnetic core is fixed in second mounting base 4
3, one end of the electromagnetic core 3 is oppositely arranged with the measuring surface 11 of crankshaft position sensor 1, is wound on the electromagnetic core 3
Electromagnetic coil 5, the electromagnetic coil 5 are connected in series by conducting wire and switch 6, AC power 7 and frequency converter 8；First peace
Dress 2 and second mounting base 4 of seat is fixed on sweat box or vibration mechine.One end of the 3 face measuring surface 11 of electromagnetic core
The distance between measuring surface 11 of crankshaft position sensor 1 is 0.2 ~ 3mm.Preferably, the 3 face measuring surface of electromagnetic core
The distance between 11 one end and the measuring surface 11 of crankshaft position sensor 1 are 2 ~ 3mm.
During specific works, crankshaft position sensor 1 is fixed in the first mounting base 2, electromagnetic core 3 is fixed on second
In mounting base, 2 and second mounting base 4 of the first mounting base is fixed on sweat box or vibration mechine, electromagnetic core 3 and electricity
The electromagnet that magnetic coil 5 forms is closed in switch 6 and is powered, because power supply is AC power, the direction in the magnetic field of generation
Meeting cyclically-varying adjusts the power frequency in series circuit by frequency converter 8, so as to adjust the direction change in magnetic field, passes through
Effect of the electromagnet real simulation signal panels under different rotating speeds to crankshaft position sensor 1, can be to crankshaft position sensor
Signal detection is carried out when working under the conditions of high/low temperature or vibration test.The experimental rig is simple in structure, small, can
It more easily configures on sweat box or vibration mechine, so as to detect crankshaft position sensor under various operating conditions
Export signal.
The above is only the preferred embodiment of the utility model, it is noted that for the common skill of the art
For art personnel, on the premise of the utility model principle is not departed from, several improvements and modifications can also be made, these improve and
Retouching also should be regarded as the scope of protection of the utility model.
