Abstract

The invention relates to an ultrasonic amplitude-change pole, in particular to an ultrasonic amplitude-change pole with a frequency modulation sucker. The problem that stable frequency modulation is difficult to achieve through a traditional ultrasonic amplitude-change pole frequency modulation technology is solved. The ultrasonic amplitude-change pole with the frequency modulation sucker comprises an ultrasonic amplitude-change pole body and further comprises the frequency modulation sucker. The frequency modulation sucker comprises a cylindrical magnetic conductive sleeve, a cylindrical yoke, M arc-groove-shaped permanent magnets, M arc-groove-shaped electromagnets, a cylindrical shell, a circular-ring-shaped top cover and a circular-ring-shaped bottom cover, and M is a positive integerand is greater than or equal to 2, wherein a cylindrical section of the ultrasonic amplitude-change pole body faces upwards, and two symmetrical guide grooves are formed in the side face of the cylindrical section of the ultrasonic amplitude-change pole body in the axial direction; and the lower ends of the two guide grooves are closed, and the upper ends of the two guide grooves penetrate throughthe upper end face of the cylindrical section of the ultrasonic amplitude-change pole body. The ultrasonic amplitude-change pole is suitable for ultrasonic machining.

Description

technical field

[0001] The invention relates to an ultrasonic horn, in particular to an ultrasonic horn with a frequency modulation suction cup. Background technique

[0002] Ultrasonic horn is an important equipment in ultrasonic machining. Its main function is to amplify the ultrasonic mechanical vibration generated by the ultrasonic transducer and transmit it to the tool. In the actual processing process, when the processing conditions (such as the size and quality of the tool, the material of the workpiece, etc.) change, the natural frequency of the ultrasonic horn will not adapt to the processing conditions, thus affecting the processing quality and processing efficiency. At this time, in order to ensure the processing quality and processing efficiency, it is necessary to frequency-modulate the ultrasonic horn (that is, adjust the natural frequency of the ultrasonic horn), so that the natural frequency of the ultrasonic horn can adapt to the processing conditions. The...
