The invention discloses a modular oscillating circuit. The modular oscillating circuit is mainly formed by connecting a double-D trigger U5 with the model number being 7474, a crystal oscillator XT1, a crystal oscillator XT2, a ceramic capacitor C2_1, a ceramic capacitor C2_2, a phase inverter U6A, a phase inverter U6B, a phase inverter U6C and a phase inverter U6D. According to the composition of the oscillating circuit, after signals collected from the outside are received, the input signals are converted into alternating-current signals with certain amplitude and certain frequency, alternating-current oscillation is generated and serves as a signal source, and meanwhile clock pulse counting is conducted; and the oscillating circuit is also used for regularly generating beat pulses and pulse sequences in a frequency division mode and conducting digital operation, and then the oscillating circuit is used for outputting the signals processed by an oscillating control module. By the adoption of the modular oscillating circuit, the problems that according to an oscillating circuit of a high-frequency power source of an existing rapid wire feeding linear cutting machine, machining is unstable, the oscillating circuit is prone to being interfered by the outside, and parameters of elements are inconsistent during batch production are well solved. The modular oscillating circuit is stable in wave form output, high in interference resistance, simple in structure, high in practicability, and high in application and popularization value.
