Ultrasonic drilling machine circuit
Description: The ultrasonic drilling machine is essential machinery in the dairy industry for processing jewelry, primarily for natural stones, crystal agate, jade, and glass products. This machine is particularly effective for high-hardness materials, enabling both drilling and engraving. The following outlines the circuit of an ultrasonic drilling machine. The reader is referred to the specific components involved, including the electromechanical circuit routing, power supply circuit, ultrasonic oscillator circuit, driver amplifier, and power output circuit, as illustrated in the relevant schematic. The power circuit consists of a power switch, a power transformer, a two-way bridge rectifier circuit, an ammeter, a resistor, a three-terminal voltage regulator integrated circuit, and filter capacitors. The ultrasonic oscillator circuit includes resistors, an inductor, and capacitors, along with a transistor. The drive amplifier circuit comprises a capacitor, multiple transistors, an input transformer, and additional resistors. The power output circuit utilizes an input transformer winding, power amplifier tubes, resistors, an output transformer, a capacitor, and an ultrasonic transducer.
The operational analysis begins with the power switch, which converts AC 220V to a step-down voltage via the transformer. The transformer produces AC voltages of 20V and 56V. The 20V AC voltage is rectified and filtered, providing a near 24V DC voltage to the driver amplifier, while the 7815 voltage regulator supplies +15V for the ultrasonic oscillator's power supply. The 56V AC voltage is rectified and filtered, allowing the ammeter to provide approximately 60V DC for the power output circuit. Once powered, the ultrasonic oscillator generates oscillation signals that are amplified by transistors. The output circuit subsequently drives the power amplifier tubes, which energize the transducer. This conversion of ultrasonic vibration energy into mechanical energy facilitates the machining of workpieces, allowing for the formation of drilled holes or engraved patterns through the repetitive vibration of the milling head, typically composed of emery, submerged in water.
The ultrasonic drilling machine circuit integrates various components to create a robust system capable of handling high-hardness materials efficiently. The power supply circuit ensures stable voltage levels are maintained throughout the operation, while the ultrasonic oscillator generates the necessary frequencies for effective drilling and engraving. The driver amplifier plays a critical role in boosting the signals from the oscillator before they are sent to the power output stage, where the energy is transformed into mechanical vibrations. This intricate interplay of components ensures the machine operates optimally, providing precise and effective processing of various materials in the jewelry industry.Ultrasonic drilling machine is the dairy industry essential jewelry processing machinery, mainly for natural stones, crystal agate, jade and glass products, such as high hardness materials, drilling and engraving, the following describes an ultrasonic drilling machine circuit.
