Description

Technical Field

[0001] This utility model relates to the field of ultrasonic welding technology, and in particular to a split-type inclined bar welding head for ultrasonic metal welding. Background Technology

[0002] Existing wedge-type welding heads (such as those with patent number CN 221473849 U, entitled "An Ultra-Wide Ultrasonic Wedge Welding Head Structure", and patent number CN 222326982 U, entitled "A Nodal Wedge Welding Head and Ultrasonic Welding Assembly") are usually machined from a single piece of steel, which is very costly and difficult to manufacture, and it is also not easy to adjust the frequency of the welding head.

[0003] Therefore, existing technologies have shortcomings and need to be improved. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a split-type inclined bar welding head for ultrasonic metal welding, which reduces processing costs, reduces processing difficulty, and facilitates frequency adjustment of the welding head.

[0005] The technical solution of this utility model is as follows: An ultrasonic metal welding split-type inclined rod welding head is provided, comprising: a mass block, an attenuation rod, and an acoustic rod; one end of the attenuation rod is connected to the mass block, and the other end is a welding surface; the mass block and the attenuation rod are integrally formed, and the acoustic rod is mounted on the attenuation rod by screws. In this solution, the acoustic rod and the attenuation rod are not integrally formed, but are separate structures. Therefore, it is not necessary to use a large piece of sheet metal to process the mass block, attenuation rod, and acoustic rod; only one piece of sheet metal is needed to process the mass block and attenuation rod separately, and another piece of sheet metal is needed to process the acoustic rod separately, thereby effectively reducing processing costs and processing difficulty. Furthermore, since the acoustic rod is not integrally formed with the attenuation rod, different acoustic rods can be mounted on the attenuation rod, thereby enabling the application of different ultrasonic frequencies for welding, facilitating the adjustment of the ultrasonic frequency for welding.

[0006] Furthermore, there are two acoustic rods, symmetrically distributed on both sides of the attenuation rod. Using two acoustic rods, symmetrically distributed on both sides of the attenuation rod, can maintain good balance and ensure stability during use.

[0007] Furthermore, the attenuation rod is provided with screw holes, and the screws are double-ended bolts. The double-ended bolts pass through the screw holes and are connected to the two acoustic rods respectively. The use of double-ended bolts facilitates the interchange of the two acoustic rods.

[0008] Furthermore, a washer ring is provided around the screw hole, and the washer ring contacts the acoustic rod.

[0009] Furthermore, the acoustic rod is positioned at the center of the attenuation rod.

[0010] By adopting the above solution, this utility model provides a split-type inclined rod welding head for ultrasonic metal welding. By setting the acoustic rod as a separate structure, not integrally formed with the attenuation rod, it eliminates the need to process the mass block, attenuation rod, and acoustic rod from a single piece of sheet metal. Only one sheet metal is needed to process the mass block and attenuation rod, and another sheet metal is needed to process the acoustic rod separately. This effectively reduces processing costs and difficulty. Furthermore, since the acoustic rod is not integrally formed with the attenuation rod, different acoustic rods can be mounted on the attenuation rod, allowing for the application of different ultrasonic frequencies for welding and facilitating adjustment of the ultrasonic frequency during welding.

[0013] Figure 3 This is a schematic diagram of the mass block and the attenuation rod. Detailed Implementation

[0014] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0015] Please see Figures 1-3 This embodiment provides a split-type inclined rod welding head for ultrasonic metal welding, including: a mass block 10, an attenuation rod 11, and an acoustic rod 12; one end of the attenuation rod 11 is connected to the mass block 10, and the other end is a welding surface 16. The mass block 10 and the attenuation rod 11 are integrally formed, and the acoustic rod 12 is installed on the attenuation rod 11 by screws. In this solution, the acoustic rod 12 and the attenuation rod 11 are not integrally formed, but are separate structures. Therefore, it is not necessary to use a large piece of sheet metal to process the mass block 10, the attenuation rod 11, and the acoustic rod 12. Only one piece of sheet metal is needed to process the mass block 10 and the attenuation rod 11, and another piece of sheet metal is needed to process the acoustic rod 12, thereby effectively reducing processing costs and processing difficulty. At the same time, since the acoustic rod 12 is not integrally formed with the attenuation rod 11, different acoustic rods 12 can be assembled on the attenuation rod 11, thereby enabling the application of different ultrasonic frequencies for welding, and facilitating the adjustment of the ultrasonic frequency for welding.

[0016] In this embodiment, there are two acoustic rods 12, symmetrically distributed on both sides of the attenuation rod 11. Using two acoustic rods 12, symmetrically distributed on both sides of the attenuation rod 11, can maintain good balance and ensure stability during use.

[0017] In this embodiment, the attenuation rod 11 is provided with a screw hole 13, and the screw is a double-ended bolt 14. The double-ended bolt 14 passes through the screw hole 13 and is connected to the two acoustic rods 12 respectively. The use of double-ended bolts 14 facilitates the interchange of the two acoustic rods 12.

[0018] In this embodiment, a washer ring 15 is provided around the screw hole 13, and the washer ring 15 is in contact with the acoustic rod 12.

[0019] In this embodiment, the acoustic rod 12 is positioned in the center of the attenuation rod 11.

[0020] In summary, this utility model provides a split-type inclined rod welding head for ultrasonic metal welding. By designing the acoustic rod as a separate structure, not integrally formed with the attenuation rod, it eliminates the need to use a large single sheet of material to process the mass block, attenuation rod, and acoustic rod. Only one sheet of material is needed to process the mass block and attenuation rod, and another sheet is used to process the acoustic rod separately. This effectively reduces processing costs and difficulty. Furthermore, because the acoustic rod is not integrally formed with the attenuation rod, different acoustic rods can be mounted on the attenuation rod, allowing for the application of different ultrasonic frequencies for welding and facilitating adjustment of the ultrasonic frequency during welding.

[0021] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
