摘要:
An ultrasonic machining module that includes an ultrasonic transducer, wherein the ultrasonic transducer is adapted to receive a machining tool and a vibration-isolating housing adapted to be both compatible with a machining system and to receive the ultrasonic transducer therein, wherein the housing further includes at least one modification for isolating all vibrations generated by the ultrasonic transducer when the device is in operation except axial vibrations transmitted to the machining tool, thereby preventing unwanted vibrations from traveling backward or upward into the machining system.
摘要:
A device for use in a machining system, including an ultrasonic transducer, wherein the ultrasonic transducer is adapted to receive a tool bit; a housing adapted to be both compatible with the machining system and to receive the ultrasonic transducer, wherein the housing is operative to isolate all radial and other vibrations generated by the ultrasonic transducer except the axial vibrations transmitted to the tool bit; and a tool holder, wherein the tool holder and the top portion of the housing are mechanically coupled to one another.

A bushing (50) has an externally threaded portion (52) with a thread pitch P1. A collet body (20) has an internally threaded portion (31) with a thread pitch P2, which is smaller than P1 by a pitch differential, ΔP. To assembly the bushing (50) and collet body (20), the collet body is heated relative to the bushing to reduce the ΔP. The threaded portions (52, 31) of the bushing and collet body are then threadingly engaged with each other. The temperature of the bushing (50) and collet body (20) are then equalized, which tends to increase the ΔP, which causes the threaded portions (52, 31) to bind with each other and resist relative loosening rotation. The threaded portions (52, 31) may additionally/alternatively be reverse tapered and/or include variable thread pitches that cause the threaded portions to further bind with each other.

In an interference fit type cutting tool according to the present invention, a projection 8 of an edge section 2 and a hole portion 10 of a shank section 3 are fitted by shrinkage fitting. The shank section 3 is provided with an insertion hole 14 that is coaxial with the center axis O2 thereof, and a threaded hole 14b is provided in a part thereof. A rodlike set screw 15 is in threaded engagement with the insertion hole 14, and a leading end portion 15a thereof can project into a space 13 between the projection 8 and the hole portion 10. By screwing the set screw 15 in to press an end face 8b of the projection 8 of the edge section 2 in a heated state, the edge section 2 can be detached from the shank section 3, and the edge section 2, the shank section 3, and the like can be replaced without causing the problem of waste oil disposal and without chipping the edge section 2 or the like.

The invention relates to a tool head having a shrink-fit chuck (10) that has an axial receiving hole (22), and having a tool (12) that is insertable by way of its cylindrical tool shank (24) into the receiving hole (22), which is open at the front end of the shrink-fit chuck (10), and is fixable therein by thermal shrinking of the shrink-fit chuck (10). According to the invention, it is proposed that the shrink-fit chuck (10) has, in its front end portion, an annular recess (30) that radially widens the receiving hole (22) and is open at the end side, and that a function ring (14) is positioned on the tool shank (24), wherein, in the shrink-fitted state, the tool shank (24) is frictionally fixed in the receiving hole (22) and the function ring (14) sits at least partially in the annular recess (30).

A tool holder (A) has a chuck portion (2) formed with a retaining bore (20) in which a cutting tool (30) can be inserted. The cutting tool (30) is formed with flat surfaces (32) extending from the end of the cutting tool to be inserted first into the bore (20), and with a circumferential groove (33) at the rear ends of the flat surfaces. When the cutting tool is inserted into the retaining bore (20), protrusions (21) pass through spaces (S) defined between the flat surfaces and the inner wall of the retaining bore and fitted in the groove. In this state, when the cutting tool is turned, the protrusions are moved in the length direction of the groove and engage the side edges of the groove, thus preventing the cutting tool from being pulled out of the chuck portion. When the anti-pull-out protrusions are fitted in the groove, anti-rotation protrusions (22) are located on the flat surfaces. When the cutting tool is turned, the anti-rotation protrusions (22) are received in ends of the respective spaces (S), thereby preventing rotation of the cutting tool relative to the chuck portion. The tool holder (A) is split into two separate members (1 and 2) between the protrusions (21 and 22), and the separate members (1 and 2) are joined together by electron beam welding.
