  • the shank provided on the shank makes uniform contact over a wide area at the open end face of the tool holder, and provides smooth and powerful driving in the longitudinal direction. Since the drive source is the open end face of the tool holder, deformation due to continuous driving for a long time is unlikely to occur, and even if deformation occurs, it is easy to visually determine the situation. Both the tool cover and the open end face of the tool holder can be easily and quickly corrected.

  • ultrasonic vibration as a drive source
  • the method of driving the tool D free by making the shank end face d3 of the tool D abut the hole bottom face b3 with the hole bottom face b3 of the tool holder B as a drive source part is as follows. There is a limit to the diameter of the round hole b2 due to the outer diameter of the tool holder B, so the area of the hole bottom b3 is limited and small. However, it had a problem that the time required for the work was extremely long.
  • the bottom surface b 3 of the tool holder B which is the drive source, is gradually roughened and deformed by continuously driving the tool D, and the shank end surface d 3 of the tool D is also driven repeatedly.
  • the burr does not easily reach the bottom of the hole, the driving capacity will naturally decrease, and the tool D will not move freely. It had a complicated problem that these deformations had to be corrected frequently because it became difficult to remove them.
  • the present invention has been made in view of the above-mentioned problems of the conventional technology, and aims at the high frequency, which is a characteristic of ultrasonic waves. It is capable of exerting powerful vibrations, making full use of its power as a drive source for engraving, embossing, cutting, etc., and for tools and tool holders through repeated driving. The generated deformation has little effect on the driving force, and it is intended to provide a tool and a tool holder that can easily correct the deformation. Disclosure of the invention

Abstract

Un outil à main à ultrason permet à un outil (1) d'effectuer un mouvement de va-et-vient régulier, puissant et aisé par l'intermédiaire d'un porte-outil (2) utilisant les vibrations ultrasonores comme source d'entraînement. La queue (1c) de l'outil (1) est introduite dans un trou rond (3) du porte-outil (2) de sorte qu'un entraînement libre soit assuré au niveau d'une face d'extrémité ouverte (2a) de ce dernier (2). Un collier (1b) prévu sur la queue (1c) de l'outil (1) procure une plus grande surface de butée et permet d'assurer un entraînement efficace. Ce dispositif permet de réaliser efficacement des opérations d'usinage telles que la gravure et l'estampage sur du métal ou un autre matériau. En outre, il est improbable que la butée se déforme sous l'effet du mouvement de va-et-vient. Il est néanmoins possible de remédier rapidement et facilement à une déformation, ce qui permet d'utiliser aussi bien l'outil (1) que le porte-outil (2) sur la totalité de leurs durées de vie.
