Optionally, the magnetic core 200 is ferrite. In this embodiment, the sealing member is a sealant.
In the electromagnetic receiving device 10, the magnetic core 200 is arranged in the mounting groove 110, the coil 300 is arranged in the accommodating groove 210 of the magnetic core 200, and the magnetic core 200 and the coil 300 are sealed in the mounting groove 110 through the sealing element, so that the coil 300 and the magnetic core 200 are wrapped in a closed space formed by the receiving ring 100 and the sealing element, thereby the relatively fragile magnetic core 200 and the coil 300 are well protected, the magnetic core 200 and the coil 300 are prevented from being damaged due to collision or damp in the ultrasonic processing process of a workpiece, and the service lives of the magnetic core 200 and the coil 300 are prolonged. The coil 300 is disposed in the accommodating groove 210 of the magnetic core 200, which can enhance the inductance of the coil 300 on one hand and provide one more layer of protection for the coil 300 on the other hand.
In this embodiment, the mounting groove 110 is an annular groove disposed along the circumferential direction of the receiving ring 100; the magnetic core 200 is an annular magnetic core 200, and the accommodating groove 210 is an annular groove arranged along the circumferential direction of the magnetic core 200. Therefore, the coil 300 is convenient to wind in the magnetic core 200, and when the receiving ring 100 is sleeved on the cutter body 20, the cutter body 20 is positioned at the center of the coil 300 and the magnetic core 200, so that good transmission of high-frequency electric energy signals is ensured.
Specifically, a first wiring opening 111 is provided on the inner wall of the mounting groove 110, and the first wiring opening 111 is used for leading out the wiring of the coil 300 in the mounting groove 110. In this manner, the wiring of the coil 300 is facilitated to pass through the receiving ring 100 and be led out of the mounting groove 110.
In this embodiment, the edge of the receiving ring 100 at the bottom of the first connection opening 111 is a bottom edge 120, and the bottom edge 120 is higher than the bottom of the mounting groove 110. Therefore, the wire passing is convenient, the rigidity of the receiving ring 100 can be ensured, and the magnetic core 200 and the coil 300 arranged in the receiving ring 100 can be well protected.
Further, a second wire connection opening 211 is disposed on the inner wall of the accommodating groove 210, and the second wire connection opening 211 is disposed at a position corresponding to the first wire connection opening 111.

On the one hand, the windings of the coils 300 are generally stacked layer by layer from the inside to the outside of the accommodating groove 210, so that there is one connection each of the inside and the outside of the coils 300, and the connection of the two coils 300 is finally led out from the inner groove wall of the accommodating groove 210. This arrangement may facilitate, on the one hand, the outer wiring of the coil 300 to pass through the core 300 from the wiring hole 212 and out from the second wiring opening 211. Because the wiring hole 212 is disposed at the bottom of the accommodating groove and is communicated with the second wiring opening 211, a certain wire passing space is left for the outer wiring of the coil 300, so that the overall height of the coil 300 is not affected, and the subsequent glue filling process is prevented from being hindered. On the other hand, the subsequent glue filling operation is also convenient to carry out. When the sealant is filled, a part of sealant is filled into the accommodating groove 210, and the other part of sealant flows out from the second wiring opening 211 to fill the gap between the receiving ring 100 and the magnetic core 200. The bottom of the accommodating groove 210 is provided with a wiring hole 212, and the wiring hole 212 is connected with the second wiring opening 211, so as to keep the same level of the sealant in the accommodating groove 210 and the sealant in the mounting groove 110, and make the sealant distribution uniform. In this embodiment, the gap between the first wiring opening 111 and the wiring of the coil 300, and the gap between the second wiring opening 211 and the wiring of the coil 300 are filled and sealed by sealant. Thus, the first and second wire openings 111 and 211 have good sealing performance, prevent cutting fluid and other dirty contaminants from entering the receiving ring 100, and fix the wire of the coil 300 so as not to shake.
In this embodiment, the wire hole 212 is disposed inside the outer groove wall of the accommodating groove 210, i.e. the wire hole 212 does not penetrate the outer groove wall of the accommodating groove 210. This arrangement can increase the rigidity of the magnetic core 200 and strengthen the protection of the coil 300.
