Example Embodiment

[0021] in Figure 1-4 In the illustrated embodiment, it includes three parts: a handle part 1, a low-frequency mechanical vibration part 2, and an ultrasonic vibration part 3. The tool handle part 1 is rigidly matched with the low-frequency vibration part 2 through the flange 102, screws, and ensures that the two parts are on the same axis; the low-frequency mechanical vibration part 2 is protected by the flange at the lower end of the low-frequency vibration shaft 219 and the ultrasonic part 3 The cover is matched and fastened by screws; the end of the horn 305 of the ultrasonic part 3 is provided with threads and cavities, which cooperate with a standard ER chuck to realize tool clamping. The center lines of the three parts are based on and coincide with the center of the HSK standard interface 101. The standard interface 101 of the tool holder part 1 is integrated with the flange 102. The HSK standard interface 101 at the upper end is used to connect to the spindle of the m...

Abstract

The invention discloses a cutter handle capable of realizing composition of ultrasonic vibration and low-frequency vibration. According to the cutter handle, low-frequency vibration is realized by utilizing mechanical movement formed by a motor, double cams and a vibration sliding block structure, and ultrasonic vibration is realized by utilizing piezoelectric vibration energy converter consistingof piezoelectric ceramics and an amplitude-change pole; a high-frequency vibration mechanism and the low-frequency vibration mechanism of the cutter handle are connected through a low-frequency vibration shaft; and two kinds of vibration are coupled in a cutter handle axis direction; the cutter handle is compact in integral structure, proper in size and high in rigidity; the lower end amplitude-change pole is fastened with a machining tool through a standard spring clamp collet; three modes of ultrasonic vibration, low-frequency vibration and ultrasonic-low-frequency composite vibration; andultrasonic vibration machining modes of different modes can be realized according to different machining tools. The cutter handle is compact in structure and low in cost, and has a wide prospect in the aspect of research and application of an ultrasonic-low-frequency composite vibration machining technique.

Description

technical field [0001] The invention relates to a vibrating tool holder, in particular to an axially reciprocating vibrating tool holder capable of realizing low-frequency vibration, ultrasonic vibration, and ultrasonic low-frequency combination, and belongs to the field of mechanical processing equipment. Background technique [0002] With the development of the aerospace industry, the structure of the overall blisk is becoming more and more complex, the overall thickness of the blade and the size of the flow channel between the blades are getting smaller and smaller, resulting in a further reduction in the diameter of the tool for processing the blade surface, which in turn leads to The rigidity of the overall process system for disk surface processing is extremely weak; on the other hand, the machinability of the blisk material is getting worse and worse, and it is difficult for traditional cutting to meet the requirements of the blisk machining accuracy. Ultrasonic machi...
