Problems solved by technology

Yet present ultrasonic machining device has many defects, as: the patent No. is 200310105459.X (authorized announcement number is CN100364673C), and its authorized announcement date is disclosed in the Chinese invention patent on January 30, 2008 " a kind of high-efficiency ultrasonic Processing Equipment", the machine tool can no longer perform other types of processing except for ultrasonic processing; another example: the patent application number is 200910226156.0 (publication number is CN101704219A), and its publication date is May 12, 2010 in China The invention patent application discloses "A Kind of Ultrasonic Processing Equipment". Although this equipment can realize ultrasonic processing and non-ultrasonic processing such as turning and grinding on the same machine tool, due to its complex structure and poor interchangeability, it cannot be processed by simple Ultrasonic processing can be realized on any ordinary CNC machine tool, therefore, it affects the promotion and use of ultrasonic processing
[0003] At present, most ultrasonic processing devices use the power supply method of the brush, in which the slip ring is always in contact with the power supply brush, so the wear or damage is serious. Therefore, in addition to the frequent replacement of the power supply brush, the stability and reliability cannot be guaranteed. In addition to the problem of high processing work, in order to reduce the wear or damage of the slip ring, its rotation speed is also limited, so it cannot respond to the request of high-speed rotation
The patent application number is 200680024192.3 (the publication number is CN101213042A), and the Chinese patent application published on July 2, 2008 discloses a "spindle device for ultrasonic machining", in which a non-contact power supply method is adopted, but since only a single two One coil induction, low induction efficiency, unable to meet the needs of high-power ultrasonic processing
In addition, the document "Research on Three-dimensional Simulation of Loosely Coupled Transformer Based on ANSYS" published in the journal "World Electronic Components" in June 2010 provides a non-contact energy transfer device, that is, the upper and lower tank-shaped magnetic rings are non-contact. type transformer, the primary and secondary coils are respectively wound in the upper and lower pot-shaped magnetic cores, which are used in the controllable eccentric device of the core component of the rotary steerable intelligent drilling system in this document, and the non-contact energy transmission method can also be Used in ultrasonic processing devices, but its induction efficiency is still very low, and high power transmission cannot be achieved

Embodiment 1

[0087] Figure 11 It shows the structure of Embodiment 1 of a rotary ultrasonic head based on the machine tool attachment of the present invention. The main components include an ultrasonic vibration working device, a non-contact collector ring, a main shaft 17, a tool handle 16, a support shell 12, and a shift fork 13. The first bearing 11, the second bearing 14, the main side insulating cage 22 of the collector ring, and the secondary side insulating cage 23 of the collector ring.

[0088] Some accessories are not shown among the figure, these accessories can be changed under the situation that the gist of the present invention remains unchanged.

[0089] One end of the main shaft 17 has an inner cavity D, and the inner cavity D is coaxial with the main shaft 17. Tool handle 16 is installed, the rotation axes of ultrasonic vibration working device (18, 9, 8, 7, 6), main shaft 17 and tool handle 16 are on the same straight line, and tool handle 16 is installed on the machine...

Embodiment 2

[0097] like Figure 12 Shown is the structure of Embodiment 2 of a rotary ultrasonic head based on machine tool attachment of the present invention, which is the same as Figure 11 The same parts of the illustrated embodiments will not be repeated, and only the differences will be described.

[0098] In the second example, the Figure 11 The split tool holder 16 and the main shaft 17 in the Figure 12The one-piece tool holder main shaft 24 shown in , that is, cancel the connecting part between the two under the premise that the respective functions of the tool holder and the main shaft remain unchanged, and manufacture the two as a whole. The one-piece tool holder main shaft 24 is due to the The handle and the main shaft are a whole and cannot be disassembled, that is, a rotating ultrasonic head corresponds to a certain type of tool handle, and can only be installed on the machine tool spindle that matches the type of tool handle. The interchangeability of the integrated typ...

Embodiment 3

[0100] like Figure 13 Shown is the structure of Embodiment 3 of a rotary ultrasonic head based on machine tool attachment of the present invention, which is the same as Figure 11 The same parts of the illustrated embodiments will not be repeated, and only the differences will be described.

[0101] Figure 13 The third embodiment shown does not have Figure 11 The first bearing 11 and the second bearing 14, the shift fork 13 and the accessories equipped for installing the bearings in the shown embodiment one, but the end of the support shell 12 close to the tool handle is directly fixedly connected with the machine tool bed, in this Under the premise that the purpose of the invention remains unchanged, the connection method can be that a magnetic seat (not shown in the figure) is set near the end of the support shell 12 near the handle of a knife, or use other connection methods. use Figure 13 In the third embodiment shown, the requirement for the coaxiality of the supp...
