Description

Technical Field

[0001] The utility model relates to the technical field of ultrasonic metal welding, in particular to an ultrasonic metal welding machine. Background Art

[0002] Ultrasonic metal welding machines primarily use ultrasonic waves to drive the welding head into high-frequency vibration, causing it to rub against the metal product, generating high temperatures and welding the metal parts. In practice, the ultrasonic transducer and amplitude modulator are often mounted within the machine frame. Due to the machine's internal layout, the welding range is generally limited to 50mm. If the weld area exceeds this range, the product position must be adjusted again, which is inefficient. The adjustment process is also subject to human influence, resulting in unstable weld quality. Utility Model Content

[0003] In response to the problems existing in the above-mentioned prior art, the utility model provides an ultrasonic metal welding machine, in which the transducer, amplitude modulator and welding head are all arranged on the outside of the frame, so that the installation of the clamping block is basically not restricted by the layout inside the frame. Furthermore, the amplitude modulator and welding head can be firmly supported by adopting a clamping block with a larger clamping surface and a limit surface, thereby achieving the purpose of expanding the controllable displacement range of the welding head, improving welding efficiency, and ensuring welding quality.

[0004] In order to solve the above technical problems, a technical solution adopted by the present invention is as follows:

[0005] An ultrasonic metal welding machine includes a frame, a transducer, an amplitude modulator, a welding head and a positioning seat; the frame is provided with a driving device and a guide rail extending in the Z direction, the guide rail is provided on the outer wall of the frame, and a clamping block is provided on one side of the Y direction, the clamping block is transmission-connected to the driving device and can slide along the guide rail under the drive of the driving device; the amplitude modulator is detachably fixed to the clamping block, and the welding head and transducer are respectively provided at both ends of the amplitude modulator, the welding head extends along the X direction and is embedded in the clamping block, its welding end is provided at the Z-down end of the welding head and directly above the positioning seat in the Z direction, and the transducer extends to the outside of the frame.

[0006] As a further elaboration of the above technical solution:

[0007] In the above technical solution, the frame is a C-shaped structure, the guide rail is installed on the outer wall of the frame, and the clamping block, welding head, amplitude modulator and transducer are all arranged on the outside of the frame.

[0008] In the above technical solution, the clamping block includes a slider and a support block that are detachably connected by a locking member. The support block is arranged at one end of the slider in the X direction, and both are provided with a first mounting hole groove for clamping the modulator. The two first mounting hole grooves match each other and extend along the X direction.

[0009] In the above technical solution, the lower end portion of the slider is provided with a second mounting hole groove adapted to the welding head and extending along the X direction on the side of the first mounting hole groove in the X direction.

[0010] In the above technical solution, the welding head is an integrally formed cross structure, whose transverse arm is installed on the clamping block, one end of its longitudinal arm is the welding end and extends to the outside of the clamping block, and the other end of the longitudinal arm extends to the clamping block, and the clamping block is provided with an avoidance hole groove for avoiding the longitudinal arm.

[0011] In the above technical solution, the clamping block is detachably fixed on a slide, and the slide is slidably mounted on the guide rail and is transmission-connected to the driving device.

[0012] Compared with the existing technology, the beneficial effect of the present invention is that by arranging the transducer, amplitude modulator and welding head on the outside of the frame, the installation of the clamping block is basically not restricted by the layout inside the frame. Then, by adopting a clamping block with a larger clamping surface and a limit surface, the amplitude modulator and the welding head can be firmly supported, thereby achieving the purpose of expanding the controllable displacement range of the welding head, improving welding efficiency, and ensuring welding quality.

[0019] like Figure 1As shown, the ultrasonic metal welding machine includes a frame 10, a transducer 20, an amplitude modulator 30, a welding head 40 and a positioning seat 50; the frame 10 is provided with a driving device 60 and a guide rail 1 extending in the Z direction, the guide rail 1 is provided on the outer wall of the frame 10, and a clamping block 70 is provided on one side of the Y direction. The clamping block 70 is transmission-connected to the driving device 60 and can slide along the guide rail 1 under its drive; the clamping block 70 is detachably fixed with the amplitude modulator 30, and the two ends of the amplitude modulator 30 are respectively provided with the welding head 40 and the transducer 20, the welding head 40 extends along the X direction and is embedded in the clamping block 70, the welding end thereof is provided at the Z downward end of the welding head 40 and is provided directly above the positioning seat 50 in the Z direction, and the transducer 20 extends to the outside of the frame 10. In this embodiment, the frame 10 is a C-shaped structure, the guide rail 1 is mounted on the outer wall of the frame 10, the clamping block 70, the welding head 40, the amplitude modulator 30 and the transducer 20 are all arranged on the outside of the frame 10, and the clamping block 70 is detachably fixed on a slide 80, which is slidably mounted on the guide rail 1 and is transmission-connected to the drive device 60.

[0020] like Figure 2 As shown, in this embodiment, the clamping block 70 includes a slider 71 and a support block 72 that are detachably connected by a locking member. The support block 72 is provided at one end of the slider 71 in the X direction, and both are provided with a first mounting hole groove 2 for clamping the amplitude modulator 30. The two first mounting hole grooves 2 match each other and extend along the X direction; the lower end of the slider 71 is provided with a second mounting hole groove 3 that is adapted to the welding head 40 and extends along the X direction on the side of the first mounting hole groove 2 in the X direction.

[0021] like Figure 3 As shown, in this embodiment, the welding head 40 is an integrally formed cross structure, whose transverse arm 41 is mounted on the clamping block 70, one end of its longitudinal arm 42 is a welding end and extends to the outside of the clamping block 70, and the other end of the longitudinal arm 42 extends to the clamping block 70, and the clamping block 70 is provided with an avoidance hole groove 4 for avoiding the longitudinal arm 42.

[0022] It is understandable that if Figure 1 As shown, since the transducer 20, amplitude modulator 30, and welding head 40 are all located outside the frame 10, the design of the clamping block 70 is essentially unconstrained by the internal layout of the frame 10. By designing the clamping block 70 with a larger clamping surface and a larger limit surface, it is possible to firmly clamp and fix the appropriate amplitude modulator 30 and welding head 40. In combination with a higher-power transducer 20, the controllable displacement range of the welding head 40 can be expanded, that is, the single processing range of the welding head 40 can be expanded, while ensuring welding quality. It has been verified that the single welding range of this embodiment can be expanded to within 100 mm, which can reduce the operator's frequency of material changes and transfers, improve welding efficiency, and ensure welding quality.

[0023] The above does not limit the technical scope of the present invention. Any modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention are still within the scope of the technical solution of the present invention.
