Problems solved by technology
According to this support method, the stable vibration of the complex of the ultrasonic vibrating body and the tool can indeed be realized, but this will cause the following problem, that is, a considerable part of the vibration energy of the ultrasonic vibration generated by the ultrasonic vibrating body is transmitted through the above-mentioned The flange (support) leaks to the sleeve side, so a sufficient amount of ultrasonic energy cannot be transmitted to the tool, so that ultrasonic machining using ultrasonic vibrations cannot be expected to be performed at a predetermined machining efficiency

Embodiment Construction
[0040] figure 2 In the figure, the support structure according to the first embodiment of the present invention is shown by taking the support structure of the elongated ultrasonic vibrating body equipped with the drill bit 16 as an example. figure 2 The supporting structure of the ultrasonic vibrating body is that the ultrasonic vibrating body is supported and fixed on the supporting and fixing structure including the base 8, the motor 9a arranged on the base, the support (ball screw shaft) 11, the ball nut 12 and the lifting table 14. 1 structure. figure 2 Among them, the ultrasonic vibrating body 1 is an ultrasonic vibrating body generally called a Langevin vibrator. A drill 16 is provided at the lower end of the ultrasonic vibrating body 1 . Near the lower end of the ultrasonic vibrating body 1 is provided with an annular flange 2a integrally formed with the ultrasonic vibrating body 1, and at the upper end (top) of the ultrasonic vibrating body 1 is provided a Annul...

Provided is a support structure that makes highly efficient application of vibrational energy to a tool possible by supporting a vibrating complex, which comprises the tool and an ultrasonic vibrator, with a high degree of stability and limiting the leakage of ultrasonic vibrational energy generated by the ultrasonic vibrator to the support (securing support) for the complex to a low level. A support structure for engaged support that results from attaching flanges to a tool-equipped ultrasonic vibrator and bringing one surface of the flanges into contact in a stressed state with separately provided flanged support surfaces formed on a securing body. The flanges on the ultrasonic vibrator are not bonded to the flanged support surfaces of the securing body and have a configuration such that the flanges of the ultrasonic vibrator, when engaged and supported by being in contact with the support surfaces of the securing body, ultrasonically vibrate in the flange thickness direction when the ultrasonic vibrator is vibrating.
Description
technical field [0001] The invention relates to a support structure for an ultrasonic vibrating body equipped with a tool. In more detail, the supporting structure of the ultrasonic vibrating body equipped with a tool according to the present invention can make the ultrasonic vibrating body equipped with a tool for material processing such as a drilling tool, a cutting tool, a grinding tool or a grinding tool be in a stable state, And the ultrasonic vibration energy generated by the ultrasonic vibrating body can be efficiently transmitted to the tool. Background technique [0002] Conventionally, ultrasonic vibration bodies or ultrasonic vibrators are attached to various tools such as drilling tools such as drills, cutting tools such as cutting blades, disc-shaped cutting tools such as dicing machines, circular grinding tools, and circular grinding tools. And by applying electric energy to the ultrasonic vibrating body to generate ultrasonic vibrations, and transmitting the...
