Embodiment 1
As shown in Figure 1-2, a kind of integrated hydraulic cylinder structure with displacement detection function, including cylinder barrel 1, primary coil
2nd, insulating barrier 3, A phases differential coil 4, B phases differential coil 5, screen layer 6 and piston group 7, piston group 7 are installed on inside cylinder barrel 1,
It can be moved along cylinder barrel, described primary coil 2 is wrapped on cylinder barrel 1, and insulating barrier 3 is covered on primary coil 2, and A phases are differential
Coil 4 and B phases differential coil 5 is respectively wound around on insulating barrier 3, and by being boundary among cylinder barrel 1, side is that A phases differential coil 4 twines
Around position, other side is the winding position of B phases differential coil 5, the outermost layer covering of A phases differential coil 4 and B phases differential coil 5
There is screen layer 6.Bleeder screw 8 is placed in the exhaust for being used for hydraulic cylinder on cylinder barrel, and connecting lug 9 is used for machine of the hydraulic cylinder to outside
Tool connects.Piston group includes piston and piston rod.
The principle of the present embodiment is：Differential coil is wound outside Barrel of Hydraulic Cylinders, using piston as inductive iron core, is led to
Secondary coil induction piston movement position is crossed, so as to realize the function of detection piston cylinder relative position, primary coil is produced and encouraged
Magnetic magnetic field, magnetic field is produced inside hydraulic cylinder through Barrel of Hydraulic Cylinders, its motion directly affects A phases, B phase coils.
Operation principle is as follows：In work, high frequency sinusoidal signal is applied on primary coil, produces high frequency sinusoidal alternation magnetic
, the position of piston and piston rod has influence on above differential secondary coil the magnetic field intensity sensed, is closed so as to export with position
It is consistent high-frequency modulation signal, then by rear class demodulator circuit and by the detection extraction electric signal related to piston movement.
