Embodiment Construction

[0019] Please check Figure 1 to Figure 4 , a preferred embodiment of an adjustable magnetic block magnetically supported rotating ultrasonic handle, the adjustable magnetic block magnetically supported rotating ultrasonic handle includes a machine tool, a handle housing 10, an ultrasonic system, and several block magnets 31 And ring magnet 32.

[0020] The tool handle housing 10 is rotatably mounted on the machine tool.

[0021] In this embodiment, the handle housing 10 is provided with a plurality of first threaded holes 11 penetrating through the inside and outside of the handle case 10 and arranged at intervals in a ring. The inner ends of the first threaded holes 11 correspond to the ring magnets 32 . In this embodiment, the number of the first screw holes 11 is set to three, and in practical applications, the number of screw holes can also be changed according to actual processing needs, and a corresponding number of block magnets 31 can be provided.

[0022] In this e...

Abstract

The invention discloses a rotating ultrasonic tool shank supported by the magnetic force of adjustable magnets. The rotating ultrasonic tool shank comprises a machine tool, a tool shank casing rotationally mounted on the machine tool, and an ultrasonic system mounted in the tool shank casing, wherein the ultrasonic system comprises an amplitude-change pole; the front end of the amplitude-change pole is fixedly connected with the tool shank casing; the rotating ultrasonic tool shank further comprises a plurality of blocky magnets mounted in the tool shank casing and an annular magnet fixedly mounted at the rear end of the amplitude-change pole; the blocky magnets are distributed at the periphery of the annular magnet at equal intervals; the polarity of the inner surface of the blocky magnet is the same as that of the peripheral surface of the annular magnet; the rear end of the amplitude-change pole can be relatively fixed with the tool shank casing in the radial direction in a non-contact way through the effect that the same polarities of the blocky magnet and the annular magnet mutually repel. The rotating ultrasonic tool shank improves the stability and the radial stiffness of the ultrasonic system, and can neither influence the transmission of axial ultrasonic vibration wave nor cause ultrasonic energy loss and heating of the system. Meanwhile, the magnetic force between the blocky magnet and the annular magnet can be adjusted according to the practical requirements.

Description

technical field [0001] The invention relates to an adjustable magnetic block magnetically supporting a rotating ultrasonic handle. Background technique [0002] Hard and brittle materials such as engineering ceramics, optical glass, and artificial crystals are widely used because of their high hardness, good chemical stability, resistance to oxidation, wear resistance, and corrosion resistance. However, these hard and brittle materials have extremely high hardness and brittleness, and their processing is very difficult. Ultrasonic machining is a new processing method that has been gradually developed and applied in recent decades. A large number of theoretical and experimental studies have shown that ultrasonic machining has a process effect that cannot be compared with ordinary processing methods in the precision machining of hard and brittle difficult-to-machine materials. In order to make better use of the advantages of ultrasonic processing, ultrasonic processing is usu...
