Problems solved by technology

[0003] For example, in a conventional tool holder that rotates a nut (an example of an operation member) to press a collet (an example of a fastening member) into the collet (an example of a fastening member), friction occurs between the nut and the collet when the nut is tightened. When the sleeve is pressed in while being twisted and deformed in the direction of rotation of the nut
As a result, when the axis center of the collet deviates from the axis center of the holder body, the clamping accuracy of the tool may decrease

no. 1 approach

[0044] Such as figure 1 As shown, the tool holder 1 includes: a collet 4 (an example of a fastening member) for fastening and holding a tool 5 , a holder body 2 , and a nut N (an example of an operating member) provided with a holding member 3 . The holder main body 2 has, at the front end, an accommodation portion 25 that accommodates the collet 4 along the axis AX. In this embodiment, the collet 4 is inserted into the interior of the housing portion 25 of the holder main body 2 along the axis AX. The holding member 3 is configured to house the collet 4 and to be movable integrally with the collet 4 in the axial direction X based on the axis AX. The nut N is externally mounted on the holder main body 2 and internally houses the holding member 3 . Thereby, the collet 4 fastens the tool 5 by the operation of the nut N. It should be noted that the axis AX of the holder main body 2 corresponds to the rotation axis of the tool holder 1 . Hereinafter, the direction along the a...

no. 2 approach

[0060] In this embodiment, if image 3 As shown, the vibration generating part 11 is provided on the nut N. As shown in FIG. exist image 3 Among them, the vibration generating portion 11 protrudes from the outer peripheral surface A of the nut N. As shown in FIG. Similar to the first embodiment, in this embodiment, the vibration generating part 11 is also provided in a ring shape in all the following embodiments and modifications. Although not shown, the vibration generating part 11 may be assembled at a position radially inner R2 from the outer peripheral surface A of the nut N. As shown in FIG.

no. 3 approach

[0062] In this embodiment, if Figure 4 As shown, the vibration generator 11 is provided on the jacket 4 . exist Figure 4 Among them, the vibration generating part 11 is protrudingly provided on the front end surface 4a of the jacket 4 . Although not shown, the vibration generator 11 may be assembled on the proximal side X2 in the axial direction from the front end surface 4 a of the collet 4 , or may be provided along the axial direction of the tool 5 .

Abstract

The tool holder (1) has: a fastening part (4), which fastens and holds the tool (5); the main body (2) of the holder has a front end which accommodates the fastening part (4) along the axis (AX) The accommodating part (25); and the operating part (N), which is externally mounted on the holder main body (2) and the fastening part (4) is installed inside, the fastening part (4) is installed on the holder main body (2), and the tool is held The part (1) is configured such that the fastening part (4) fastens the tool (5) through the operation of the operating part (N), and when the fastening part (4) fastens the tool (5), the fastening The contact portion (T) of the member (4) and the holder main body (2) is vibrated.

Description

technical field [0001] The invention relates to a tool fastening method of a tool holder and the tool holder. A fastening component installed on a main body of the holder fastens and holds the tool. Background technique [0002] In recent years, due to the development of machine tools, the maximum rotational speed of the spindle of the tool is getting faster and faster. Therefore, especially in mold processing or micro-machining, there is an increasing demand for small-diameter high-precision clamping parts that can withstand precision machining under ultra-high-speed rotation. [0003] For example, in a conventional tool holder that presses a collet (an example of a fastening member) by rotating a nut (an example of an operation member), friction occurs between the nut and the collet when the nut is tightened. A case where the sleeve is pressed in while being twisted and deformed in the direction of rotation of the nut. As a result, when the axial center of the collet dev...
