Embodiment 1

[0023] Such as figure 1 , figure 2 Shown, guide rod 5 is housed in guide sleeve 2. Support 6 is installed in guide sleeve 2, present embodiment adopts upper and lower layers, and electromagnet 7 is housed on support 6. figure 2 The solenoid shown is U-shaped. Since the inductance of the coil is a function of the displacement of the guide rod, the voltage across it is also a function of the displacement of the guide rod.

[0024] Such as image 3 As shown, the circuit is composed of a bandpass circuit 1a, a primary amplifier circuit 2a, a differential detection circuit 3a, a demodulation circuit 4a, and a low-pass filter circuit 5a. At the input end of the linear power amplifier of the magnet coil, a high-frequency signal is injected as a test signal for the position of the guide rod. In addition to the DC component acting on the resistor, the voltage at both ends also has the AC component of the high-frequency signal acting on the inductor. The band-pass circuit 1a is u...

Embodiment 2

[0027] Figure 4 It is the schematic diagram of the self-detection system for the eccentricity of the guide rod. The circuit is composed of bias circuit, detection circuit, and control circuit.

[0028] The signal generated by the pulse width modulation signal (PWM) generator 9a is input to the bias circuit 10a, and a bias magnetic field is generated in the electromagnet. Since the inductance of the electromagnet is a function of the displacement of the guide rod, the carrier voltage (or current) component of the PWM extracted from the control electromagnet contains the displacement information of the guide rod. Because of the control current, in addition to the PWM carrier component of the mutual induction of the bias coil in the control voltage (current), there is also the voltage (including self-induction voltage) generated by the control current on the control solenoid coil. Therefore, the output voltage on the control electromagnet coil must pass through the resonant ci...

Embodiment 3

[0031] In this embodiment, the guide sleeve is equipped with a sensor, and the sensor is used to detect the displacement of the guide rod relative to the guide sleeve, so as to realize the automatic centering of the guide rod in the guide sleeve.

[0032] Figure 5 It is the schematic diagram of the self-detection system for the eccentricity of the guide rod. The circuit is composed of a sensor 14a, a controller 6a-3, a power amplifier 1 8a-3, a power amplifier 2 8a-4, and a displacement conversion circuit 13a.

[0033] When the guide rod is eccentric, the sensor 14a detects that the displacement signal is converted by the displacement conversion circuit 13a, and then converted into a control current by the controller 6a-3 and the power amplifier 8a-3, and the electromagnetic force of the electromagnet is adjusted to make the guide sleeve and the guide rod Automatically centered.

[0034] If both the permanent magnet and the electromagnet are used in the above embodiment, th...
