Embodiment 1

[0039] In embodiment 1, an ultrasonic vibration compound atomization tool holder is provided, figure 1 It is a structural schematic diagram of the ultrasonic vibration compound atomization knife holder according to Embodiment 1 of the present invention, as figure 1 As shown, the ultrasonic vibration composite atomizing handle includes a pull stud 1 , a handle base 2 , a horn 5 , a piezoelectric sheet 4 , a piezoelectric sheet fixing part 3 , and a rear gland 9 . The pull stud 1 is fixed on the upper part of the knife handle base body 2 through screw connection, and the horn 5 is fixed on the lower part of the knife handle base body 2 through a bolt group composed of a plurality of fixing bolts 7 . The top of the piezoelectric sheet fixing part 3 is provided with a positioning shoulder for pressing the rear gland 9 and the piezoelectric sheet 4 ; Four piezoelectric sheets 4 are installed inside the base body 2 of the tool handle. A rear gland 9 is arranged on the upper part of...

Embodiment 2

[0061] In embodiment 2, an ultrasonic vibration compound atomization tool holder is provided, Figure 8 It is a structural schematic diagram of the ultrasonic vibration compound atomization knife holder according to Embodiment 2 of the present invention, as Figure 8 As shown, the ultrasonic vibration composite atomizing tool handle includes a tool handle base 2 , a horn 5 , a piezoelectric sheet 4 , and a piezoelectric sheet fixing member 3 . The horn 5 is fixed on the lower part of the base body 2 of the knife handle through a bolt group composed of a plurality of fixing bolts 7 . A plurality of piezoelectric sheets 4 are installed inside the handle base 2 , and the piezoelectric sheet fixing member 3 passes through the piezoelectric sheets 4 and is screwed to the horn 5 to fix the piezoelectric sheets 4 to the horn 5 .

[0062] In this embodiment 2, the structure of the handle base 2 and the piezoelectric sheet fixing part 3 for fixing the piezoelectric sheet 4 is the same...

Embodiment 3

[0067] In embodiment 3, an ultrasonic vibration compound atomization tool holder is provided, Figure 9 It is a structural schematic diagram of the ultrasonic vibration compound atomization knife holder according to Embodiment 3 of the present invention, as Figure 9 As shown, the difference between the ultrasonic vibration compound atomizing handle and the embodiment 1 is that the main structure does not include the pull stud 1, the transmission channel does not include the third transmission channel assembly 13 and the fixing ring 12, and the transmission channel does not have an external channel bottom zoom structure, and the reed 6 is arranged on the top of the tool bayonet of the horn 5 . Without the zooming structure at the bottom of the external channel and the resonant cavity 14, the ultrasonic vibration compound atomization handle can also achieve the effect of internal cooling ultrasonic atomization, and the zooming structure at the bottom of the external channel and...

Abstract

The invention belongs to the technical field of ultrasonic processing, and discloses an ultrasonic vibration compound atomization knife handle, which includes a knife handle base body, a horn and a piezoelectric sheet, and the piezoelectric sheet is arranged inside the handle base body and fixed by a piezoelectric sheet fixing part For the horn, the base body of the tool handle, the horn and the piezoelectric film fixing part are all equipped with a hollow structure; the above hollow structure is equipped with a transmission channel, including a coaxial inner channel and an outer channel, which are respectively used to transport the liquid phase Lubricating medium and gas phase medium; the bottom of the external channel is longer than the internal channel; a reed is arranged at or below the outlet of the external channel, and there is a gap between the reed and the outlet of the internal channel to mix the liquid lubricating medium and the gas phase medium space. The invention can improve the processing quality by using ultrasonic vibration, and at the same time reduce the cutting heat and cutting force in the processing area by forming an ultrasonic atomized lubricating medium, further enhance the cooling and lubrication effect, and finally increase the service life of the tool and improve the processing efficiency.

Description

technical field [0001] The invention belongs to the technical field of ultrasonic machining, and in particular relates to an ultrasonic vibration composite atomizing tool handle used in high-speed machining conditions. Background technique [0002] With the rapid development of high-tech in aerospace and other fields, the market has higher and higher requirements for product performance. Therefore, the requirements for the processing quality of materials used in it are also becoming more and more stringent. Hard and brittle materials such as ceramics and ceramic matrix composites have become the new materials that are used in the new generation of aircraft because of their good high temperature resistance, wear resistance and high specific strength. However, due to the characteristics of high hardness and high brittleness of ceramics and ceramic matrix composites, chipping and crushing are prone to occur during processing, which reduces the pass rate and performance of the p...
