Description

Technical Field

[0001] The utility model relates to an ultrasonic vibration device. Background Art

[0002] Ultrasonic transducers are devices that can convert input electrical power into mechanical power and then transmit it. Ultrasonic transducers consume less power themselves and are important components of ultrasonic welding equipment. Ultrasonic transducers are generally composed of an outer shell, a piezoelectric ceramic chip, and an electrode sheet. After the ultrasonic transducer is assembled, its internal electrode sheet will protrude outward. At present, when the ultrasonic transducer is not in use, in order to avoid damage to the protruding electrode sheet, the staff generally uses soft materials to wrap the electrode sheet to protect it. This method relies on external materials and has certain limitations.

[0003] There are transducers that do not need to rely on external materials for protection, such as an ultrasonic transducer with patent number CN218854772U, which includes a transducer body and a protective mechanism. The transducer body is composed of a transducer body and two protruding electrode sheets. The protective mechanism includes a mounting ring, and a storage cavity is symmetrically opened on the top of the mounting ring. The inner walls of the two storage cavities are provided with arc-shaped protective airbags, and the tops of the two arc-shaped protective airbags are fixedly connected with guide plates, and the tops of the two guide plates are fixedly connected with T-shaped hanging plates. The top of the transducer body is symmetrically provided with T-shaped hanging grooves, and an air supply channel is opened inside the mounting ring. Both ends of the air supply channel are provided with connecting pipes, and the front of the mounting ring is fixedly inserted with an air supply pipe. The back surfaces of the two arc-shaped protective airbags are provided with reinforcement components.

[0004] This embodiment has the advantage of improving the protection strength of the protruding electrode sheet without the need for external materials, but it has the following defects:

[0005] 1. The lower end of the transducer body is connected to the tool head through a thread, which may cause thread slippage after long-term use;

[0006] 2. The transducer can only dissipate heat through natural wind, and the heat dissipation efficiency is low. Summary of the invention

It should be understood that the data used in this way can be interchangeable under appropriate circumstances, so that the embodiments of the present application can be implemented in an order other than those illustrated or described here, and the objects distinguished by "first", "second", etc. are generally of one type, and the number of objects is not limited. For example, the first object can be one or more.

[0047] The server provided in the embodiment of the present application is described in detail below through specific embodiments and application scenarios in conjunction with the accompanying drawings.

[0048] Embodiment 1:

[0049] like Figure 1 , Figure 2 As shown, an embodiment of the present application provides an ultrasonic vibration device, including a transducer body 1, an amplitude modulator 2, a motor sheet 3 and a tool head 4, and also includes: a threaded hole 5, which is arranged at the lower end of the amplitude modulator 2; a pair of limit units 6, which can be adjusted and installed on both sides of the amplitude modulator 2, and are connected to the threaded hole 5.

[0050] Furthermore, the limiting unit 6 includes an adjusting block 7, which is movably mounted on the transducer body; a connecting rod 8, whose front end is fixedly connected to the bottom end of the adjusting block 7; a clamping block 9, which is fixedly connected to the rear end of the connecting rod 8; and a pull ring 10, which is fixedly connected to the adjusting block 7.

[0051] Furthermore, it also includes a mounting groove 11, which is arranged on the outer wall of the amplitude modulator 2, and an adjusting block 7 is movably installed inside; a slide groove 12, which is arranged on the inner wall of the threaded hole 5, and a clamping block 9 is movably installed inside; a through hole 13, which is fixedly connected between the mounting groove 11 and the slide groove 12; wherein, the connecting rod 8 is movably inserted in the through hole 13.

[0052] Furthermore, it also includes a snap ring groove 14 which is arranged on the outer wall of the tool head 4 ; wherein the clamping block 9 can be installed in the snap ring groove 14 .

[0053] Furthermore, it also includes a pair of buffer grooves 15, which are respectively arranged on both sides of the installation groove 11; a pair of sliders 16, which are respectively fixedly connected to the two ends of the adjustment block 7 and slidably installed in each buffer groove 15; a pair of buffer assemblies 17, which are installed in each buffer groove 15 and fixedly connected between the upper wall of each buffer groove 15 and the slider 16.

[0054] Furthermore, the buffer assembly 17 includes a first damping block 18 fixedly connected to the upper end of the buffer groove 15 ; a second damping block 19 fixedly connected to the upper end of the slider 16 ; and a spring 20 fixedly connected between the first damping block 18 and the second damping block 19 .

[0055] In this embodiment of the present application, due to the adoption of the above-mentioned structure, the tool head 4 is installed in the threaded hole 5 of the amplitude modulator 2 connected to the lower end of the transducer body 1. Since thread slippage is likely to occur through threaded connection, a pair of limit units 6 are installed at the lower end of the amplitude modulator 2 for fixing the tool head 4. First, pull the pull ring 10 outwards so that the connecting rod 8 drives the block 9 to move along the moving direction of the pull ring 10. At the same time, the sliders 16 on both sides of the adjusting block 7 move outwards along the buffer groove 15, and the spring 20 is compressed, and the block 9 slides into the slide groove 12, so that the part of the block 9 exceeding the threaded hole 5 moves into the slide groove 12, and then the connecting end of the tool head 4 is screwed into the threaded hole 5. The position of the clamping ring groove 14 of the tool head 4 corresponds to the position of the slide groove 12. After the tool head 4 is installed, release the pull ring 10, the spring 20 is restored, and the elastic force of the spring 20 pushes the slider 16 to drive the adjusting block 7 to move inwards. At the same time, the connecting rod 8 pushes the block 9 outwards, so that the block 9 moves outward along the slide groove 12, and a part of the block 9 is installed in the clamping ring groove 14, thereby limiting the connecting end of the tool, ensuring the stability of the installation of the tool head 4 and avoiding the phenomenon of slipping.

[0056] Embodiment 2:

[0057] like Figure 3 As shown, in this embodiment, in addition to the structural features of the aforementioned embodiments, it also includes: a heat dissipation sleeve 21, which is mounted on the transducer body 1; a heat dissipation layer 22, which is arranged between the heat dissipation sleeve 21 and the transducer body 1; a plurality of heat dissipation holes 23, which are evenly distributed on the heat dissipation sleeve 21; and the heat dissipation layer 22 is a graphene heat dissipation layer 22.

[0058] In this embodiment of the present application, due to the adoption of the above-mentioned structure, the heat dissipation sleeve 21 is sleeved on the outside of the heat exchanger body, and heat dissipation holes 23 distributed at equal intervals are opened on the side wall of the heat dissipation sleeve 21, which can dissipate heat energy to the outer wall of the heat exchanger body. A heat dissipation layer 22 is installed in the gap between the heat dissipation sleeve 21 and the heat exchanger body. The heat dissipation layer 22 is a graphene heat dissipation layer, which further improves the heat dissipation effect of the heat dissipation sleeve 21.
