Description

Technical Field

[0001] This utility model relates to the field of ultrasonic welding technology, and in particular to an ultrasonic metal welding head that is easy to replace. Background Technology

[0002] Ultrasonic metal welding technology, with its core advantages of "no open flame, no consumables, small heat-affected zone, and high welding strength", has become a key process in high-end manufacturing fields such as new energy vehicles, electronic components, and aerospace. However, different welding heads of different specifications are required for different welding needs.

[0003] Currently, existing welding heads are connected to amplitude transformers via flanges or threads. Replacement requires rotating the threaded assembly for disassembly, which is time-consuming and labor-intensive. Over time, this can cause thread stripping, leading to unstable connections and affecting the ultrasonic welding effect. Therefore, to achieve faster installation and disassembly between the welding head and the amplitude transformer, and to promote technological advancement and enhance core technological competitiveness in the industry, this application proposes a new implementation scheme for an easily replaceable ultrasonic metal welding head, which differs from existing technologies. Utility Model Content

[0004] The purpose of this invention is to solve the problems of existing ultrasonic metal welding heads that are inconvenient to install quickly and that stripping occurs after long-term threaded connections, and to propose an easily replaceable ultrasonic metal welding head.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: An easily replaceable ultrasonic metal welding head includes a welding head, a mounting block fixedly connected to the top of the welding head, and slots on both sides of the mounting block. An amplitude transformer is provided at the top of the welding head, and a first mounting groove is provided at the bottom of the amplitude transformer. A second mounting groove is provided on both inner walls of the first mounting groove. An elastic card is fixed in the second mounting groove by a buckle. Both ends of the elastic card are provided with bevels, and the elastic card engages with the slot.

[0006] Furthermore, the output shaft of the amplitude transformer is keyed with a threaded rod.

[0007] Furthermore, the depth of the slot is 0.3-0.5mm.

[0008] Furthermore, the mounting block has a T-shaped structure, and the specifications of the first mounting groove are compatible with the specifications of the mounting block.

[0009] Furthermore, the thickness of the elastic card is 0.2-0.4 mm, and its width is adapted to the width of the second mounting groove.

[0010] Furthermore, the welding head is provided with a protective coating.

[0011] The beneficial effects of this utility model are as follows: The flexible card and slot engage to enable quick assembly and disassembly of the welding head and the amplitude transformer without the need for tools. This simple operation significantly improves the efficiency of welding head replacement and solves the problem of cumbersome welding head replacement in existing technologies.

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0015] Reference Figures 1-3 An easily replaceable ultrasonic metal welding head includes a welding head 4, with an integrally formed mounting block 5 at the top of the welding head 4. The mounting block 5 has a T-shaped structure, and slots 6 are provided on both sides of the mounting block 5. The depth of the slots 6 is 0.3-0.5mm. The top of the welding head 4 is equipped with an amplitude transformer 1, which is an ultrasonic vibration amplification and transmission component that amplifies the vibration energy of the ultrasonic welding equipment and transmits it to the welding head. The bottom of the amplitude transformer 1 is provided with a first mounting groove 3, the specifications of which are compatible with the specifications of the mounting block 5. The inner walls on both sides of the first mounting groove 3 are provided with a second mounting groove 7. An elastic card 8 is fixed in the second mounting groove 7 by a buckle. The elastic card 8 can be engaged with the card groove 6. The elastic card 8 is made of phosphor bronze or stainless steel spring sheet, which has good elasticity and fatigue resistance. Both ends of the elastic card 8 are provided with bevels 9. The bevels 9 are designed so that the elastic card 8 automatically retracts when the mounting block 5 is inserted, and after resetting, it is locked into the card slot 6. The thickness of the flexible card 8 is 0.2-0.4mm, and its width is adapted to the width of the second mounting slot 7; Pull the welding head 4 outward to remove the mounting block 5 from the first mounting groove 3. Under the action of the inclined plane 9, the elastic card 8 gradually disengages from the slot 6, thereby quickly disassembling the amplitude transformer 1 from the welding head 4.

[0016] The output shaft of the amplitude transformer 1 is keyed with a threaded rod 2, which facilitates the connection between the amplitude transformer 1 and the welding equipment.

[0017] The welding head 4 is provided with a protective coating, which can be a nano-ceramic coating, and has the effects of wear resistance, insulation and hydrophobicity.

[0018] The working principle of this embodiment is as follows: When in use, hold the welding head 4 and insert the mounting block 5 into the first mounting groove 3. During the insertion process, the side of the mounting block 5 contacts and squeezes the elastic card 8, thereby causing the elastic card 8 to undergo elastic deformation into the second mounting groove 7. When the mounting block 5 is fully inserted into the first mounting groove 3, it resets and snaps into the slot 6 under the action of the elastic force of the elastic card 8, thus completing the snap-fit ​​fixing of the amplitude transformer 1 and the welding head 4. When it is necessary to replace the welding head 4, pull the welding head 4 outward to pull the mounting block 5 out of the first mounting groove 3. Under the action of the inclined plane 9, the elastic card 8 gradually disengages from the slot 6 until the mounting block 5 is completely disengaged from the first mounting groove 3, thus completing the disassembly of the amplitude transformer 1 and the welding head 4. Then, install the new welding head 4 in the same manner as described above.

[0019] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
