Referring to fig. 1-3, a first aspect of the present utility model provides a radio-emission magnetic core 10, where the radio-emission magnetic core 10 includes a top plate 100, a bottom plate 200 and a side plate 300, where the top plate 100 and the bottom plate 200 are arranged on upper and lower sides of the side plate 300, and the same sides of the top plate 100 and the bottom plate 200 are fixedly connected with the side plate 300 to form a U-shaped structure, i.e. an outer side of the top plate 100 is fixedly connected with an upper side of the side plate 300, an outer side of the bottom plate 200 is fixedly connected with a lower side of the side plate 300 to form a U-shaped structure, and for matching with a radio-reception magnetic core, radio-transmission is realized, and because the radio-reception magnetic core is generally a circular ring structure arranged on an outer periphery of a tool holder, a circular arc structure is formed by recessing a middle portion of the outer sides of the inner sides of the top plate 100 and the bottom plate 200, i.e. an inner and an outer ring structure is formed by the radio-emission magnetic core and the radio-reception magnetic core. In this embodiment, the side plates 300 are flat structures for winding the coil, and the side plates in the prior art are all arc structures, the coil needs to be wound around the side plates of the arc structures, or the wound coil has the same radian as the side plates, so that the winding process is simplified when the side plates 300 around the flat structures are relatively simple (only the winding form of the coil is illustrated in fig. 2, and the actual coil is orderly and tightly arranged when wound), and the flat structures are also simpler to manufacture compared with the arc structures, so that the wireless transmitting magnetic core 10 in this embodiment is simpler to manufacture compared with the prior art, and is convenient for winding of the subsequent coil.

In the prior art radio-emission magnetic core, the coil is all accommodated in the magnetic core in the inner and outer structures in the horizontal direction, but in the present embodiment (as shown in fig. 2), the coil 50 is wound around the side plate 300, half of the coil 50 is accommodated in the notch 400 formed by the top plate 100, the bottom plate 200 and the side plate 300, and the other half is outside the notch 400, and for the coil with the same number of turns (half of the coil or all of the coil is accommodated in the notch and only the inner layer coil acts), the volume of the radio-emission magnetic core 10 in the present embodiment is only half of the magnetic core in the prior art, that is, near half of the magnetic core material, such as ferrite, can be saved in the present application, thereby reducing the production cost.

Referring to fig. 1 and 3, both ends of the top plate 100 and the bottom plate 200 extend beyond both sides of the side plate 300, so that the top plate 100, the bottom plate 200 and the side plate 300 form a notch 400 for accommodating a coil, and since the length of the side plate 300 is smaller than that of the top plate 100 and the bottom plate 200, the radio-emission core 10 is shaped like an i as seen from a front view (fig. 3) of the radio-emission core 10, and the coil 50 is wound around the side plate 300 (see fig. 4). In the existing magnetic core structure, the length of the side plate is equal to that of the top plate, the coil is wound around the side plate, or the coil is arranged in the U-shaped groove, relatively speaking, when the length of the side plate is smaller than that of the top plate under the condition that the volume of the outer shell used for coating the wireless transmitting magnetic core is fixed, the coil with more turns can be wound on the wireless transmitting magnetic core, namely, the wireless transmission efficiency is improved. The length of the side plate is inversely proportional to the number of turns of the coil which can be accommodated, but the area of the magnetic core also affects the signal transmission efficiency, so that the length of the side plate 300 is not less than 4/5 of the length of the top plate on the basis of comprehensively considering the area of the coil turns and the magnetic core.

In this embodiment, the top plate 100 and the bottom plate 200 are disposed in parallel, so that the radial dimension, that is, the utilization rate of the cross-sectional area of the magnetic core is high, and the length of the corresponding tool shank is shortened, that is, the volume is smaller, the weight is reduced, and then the vibration energy loss is reduced. And when the lengths and widths of the top plate 100 and the bottom plate 200 are equal, that is, the areas of the top plate 100 and the bottom plate 200 are equal, the magnetic flux is further improved to thereby improve the transmission efficiency. Since the radio-emission magnetic core 10 is fixedly installed on the spindle, considering that the tool changing movement track cannot be interfered, the magnetic core area is further increased as much as possible, and chamfers are arranged at both ends of the top plate 100 and the bottom plate 200.

The top plate 100, the bottom plate 200 and the side plates 300 constituting the radio-emission core 10 may be integrally formed, simplifying the manufacturing process and thus reducing the production cost. In order to match with the ring-shaped wireless receiving magnetic core, the other sides of the top plate 100 and the bottom plate 200 form an arc structure, that is, an inner-outer ring structure, and in consideration of transmission efficiency and in order not to affect the swing arm in the tool changing process, the central angle corresponding to the arc is 45 ° -140 °.

As shown in fig. 4, a second aspect of the present utility model provides a radio transmission structure, which includes a radio receiving core 20 and a radio transmitting core 10 according to any embodiment of the first aspect, where the radio transmitting core 107 is used in cooperation with the radio receiving core 20. The radio-emission magnetic core 10 is fixed on a machine tool spindle (machine tool spindle is not shown) by an electromagnetic emission bracket 40, and the radio-reception magnetic core 20 fixed on the ultrasonic blade holder 30 is disposed corresponding to the radio-emission magnetic core 10. The wireless receiving magnetic core 20 and the wireless transmitting magnetic core 10 form an inner-outer ring structure, so that the swing arm tool changing is facilitated.

As shown in fig. 4, a third aspect of the present utility model provides an ultrasonic processing system comprising: the wireless transmission structure and ultrasonic transduction system according to any one of the embodiments of the second aspect, wherein the wireless transmission structure transmits a signal of an ultrasonic generator to the transduction system.

Specifically, the wireless transmitting magnetic core 10 is provided with a coil and then transmits a signal, the wireless receiving device 20 on the ultrasonic knife handle 30 restores the sensed signal into a high-frequency electric energy signal and transmits the high-frequency electric energy signal to the ultrasonic transducer on the ultrasonic knife handle, the ultrasonic transducer is used for converting the frequency electric signal into high-frequency mechanical vibration by utilizing the piezoelectric inverse effect of the piezoelectric vibrator and amplifying and transmitting the mechanical vibration to the cutting tool to process a workpiece through the amplitude transformer, and further ultrasonic processing can be realized by matching with a traditional common machine tool, a rotary ultrasonic processing mode is realized, the application range is larger, and compared with the traditional ultrasonic processing machine tool, the ultrasonic processing machine tool has a simple structure and lower price.

The technical features of the above-described embodiments may be arbitrarily combined, and all possible combinations of the technical features in the above-described embodiments are not described for brevity of description, however, as long as there is no contradiction between the combinations of the technical features, they should be considered as the scope of the description.

It should be noted that it will be apparent to those skilled in the art that several variations and modifications can be made without departing from the spirit of the utility model, which are all within the scope of the utility model.
