Portable ultrasonic cutter

Abstract

The invention discloses a portable ultrasonic cutter. The portable ultrasonic cutter is mainly characterized in that a piezoelectric ceramic transducer is connected with a quarter-wavelength amplitude transformer through a high-strength screw; the big end of a half-wavelength amplitude transformer is connected with the other end of the quarter-wavelength amplitude transformer, and the small end of the half-wavelength amplitude transformer is connected with a tool head; O-shaped rings A are arranged above and below a zero vibration point of the half-wavelength amplitude transformer and clamped by means of an upper fastening ring and a lower fastening ring through interference fit, and positioning pins A are arranged in opposite positions of the zero vibration point of the half-wavelength amplitude transformer; O-shaped rings B are arranged above and below a zero vibration point of the quarter-wavelength amplitude transformer, the piezoelectric ceramic transducer is fixed in a transducer shell through compression rings, and positioning pins B are arranged in opposite positions of the zero vibration point of the quarter-wavelength amplitude transformer; a ground wire inlet is formed in the outer surface of the rear end of the transducer shell, and a rear cover which is in interference fit with the rear end of the transducer shell is installed at the rear end of the transducer shell; a wind shield is fixed to the rear cover, and the rear cover is provided with an air inlet and an aviation plug wiring port; an air outlet is formed in the quarter-wavelength amplitude transformer. The portable ultrasonic cutter has the advantages that the size of an execution mechanism is small, energy consumption is low, the application range is wide, cost can be effectively reduced, and production efficiency is improved.

Description

technical field [0001] The invention relates to a general-purpose ultrasonic cutting device, which is a portable ultrasonic cutter and is suitable for solving the problem that soft, viscous and brittle materials in the food industry and tough and viscous materials in the rubber industry are difficult to process. Background technique [0002] At present, the existing ultrasonic cutting equipment mainly consists of ultrasonic driving power supply, piezoelectric ceramic transducer, horn and tool head. The piezoelectric ceramic transducer of this equipment is fixed on the transducer through the interference fit of the pressure ring In the transducer shell, the working end of the piezoelectric ceramic transducer amplifies and transmits the amplitude through the horn, and acts on the tool head. The piezoelectric ceramic transducer is connected to the ultrasonic drive power supply through the signal cable to drive the piezoelectric ceramic transducer. The device converts electrical...
