Embodiment 1
[0019] Such as figure 2 As shown, a telescopic ultrasonic welding tooling base includes a base body 1, the side of the base body has a stepped surface I11, the top of the base body 1 has a placement surface 12, and the base body 1 has a hollow cavity 13, the hollow cavity 13 The top is open, and the placement surface 12 is arranged around the top opening of the hollow cavity 13 to form a circle. The hollow cavity 13 is covered with a central shaft 2, and the hollow cavity 13 has a spring 3 inside. The bottom wall of the hollow cavity 13 has a concave groove I14 , the bottom end of the spring 3 extends into the groove I14 and is supported on the bottom end face of the groove I14, the bottom end of the spring 3 is radially limited in the groove I14, and the top end of the spring 3 is against the center axis 2 The bottom, preferably the bottom of the central axis 2 has a groove II 21, the top of the spring 3 is in the groove II 21, the top of the spring 3 is radially limited in ...
Embodiment 2
[0023] Such as image 3 As shown, the structure is basically the same as that of Embodiment 1, the difference is that no bolts are set in this structure, but a stepped surface III17 is set on the inner wall surface of the hollow cavity 13, wherein, preferably, the base body 1 is composed of upper and lower parts, and the steps The surface III17 is formed by the junction of the upper and lower parts, which is convenient for manufacturing the cross-sectional area of the hollow cavity part below the stepped surface III17 is larger than the cross-sectional area of the hollow cavity part above the stepped surface III17. A stepped surface IV18 is set on the outer wall of the central axis 2, and the step The cross-sectional area of the central axis part below the surface IV18 is larger than the cross-sectional area of the central axis part above the stepped surface III17, and the central axis 2 is limited in the hollow cavity 13 of the base body 1 by the structure of the stepp...
Embodiment 3
[0025] Such as Figure 4 As shown, the ultrasonic welding tooling includes a base and a welding head 5. The base adopts the scalable ultrasonic welding tooling base described in Embodiment 1. The bottom surface of the welding head 5 is a plane, and the welding head 5 is installed on a lifting mechanism for scalable ultrasonic welding. The base of the tooling is located under the welding head 5. When welding starts, the welding head 5 descends and presses down on the central axis 2, and the spring gradually shortens downward until the flat part of the welding head touches the seal 7 and gradually moves downward to weld the seal on On the filter end cover 6. Compared with the ultrasonic welding tool with traditional structure, the welding head is changed from a concave structure to a flat structure, and the base is changed from a three-step integral structure to a two-step split structure. The central axis, when the ultrasonic machine is welding, the central axis 2 can be stret...
