[0002] An ultrasonic welding machine is a device that generates a high-voltage, high-frequency signal from a generator, which is converted into high-frequency mechanical vibration by a transducer system. This vibration is applied to the workpiece, and the temperature at the interface is increased through friction between the workpiece surface and molecules, thereby achieving the welding purpose.

[0018] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0019] Figure 1 This is a schematic diagram of the structure of this utility model; Figure 2 This is a structural illustration of the triangular positioning mechanism of this utility model.

[0020] intention; Figure 3 This is a schematic diagram of the clamping mechanism of this utility model.

[0021] As attached Figure 1 As shown, a quick-change clamp structure for an ultrasonic welding machine includes a base 1, a slide 2, a welding head positioning seat 3, a triangular positioning mechanism 4, a fixing component 5, and a clamping mechanism 6. The base 1 and the slide 2 are slidably connected together. A clamping mechanism 6 for clamping and fixing the slide 2 within the base 1 is installed on one side of the base 1. The slide 2 is provided with a welding head positioning seat 3 and a fixing component 5. The welding head positioning seat 3 is provided with a triangular positioning mechanism 4 for positioning the welding head. The base 1 is fixed to the automatic welding machine by bolts.

[0022] As attached Figure 2As shown, the triangular positioning mechanism 4 includes an arc-shaped protrusion 41, a limiting protrusion 42, and a fixing screw 43. The welding head positioning seat 3 is provided with a U-shaped groove. The bottom of the U-shaped groove is provided with an arc-shaped protrusion 41 for matching the arc-shaped groove at the bottom of the welding head. One inner side wall of the U-shaped groove is provided with a limiting protrusion 42 for pressing against the side wall of the welding head. The other inner side wall of the U-shaped groove is threaded with a fixing screw 43 for pressing the welding head.

[0023] After the welding head is placed in the U-shaped groove of the welding head positioning seat 3, the arc-shaped groove at the bottom of the welding head engages with the arc-shaped protrusion 41, while the limiting protrusion 42 fits against the left side of the welding head. Finally, the locking screw 43 is tightened, and the locking screw 43 moves along the screw hole toward the welding head. The locking screw 43 presses down onto the welding head along an inclined downward path, thus achieving triangular positioning of the welding head within the welding head positioning seat 3.

[0024] The base 1 has a dovetail groove, and the slide 2 is a dovetail slider. The dovetail slider and the dovetail groove are matched.

[0025] As attached Figure 3 As shown, the clamping mechanism 6 includes bolts 61 and pressure blocks 62. Several bolts 61 for pushing the pressure blocks 62 are threadedly connected to one side of the base 1. The pressure blocks 62 are placed in the dovetail groove of the base 1.

[0026] When the slide 2 is inserted into the dovetail groove of the base 1, the pressure block 62 is located between the inclined surface of the slide 2 and the dovetail groove. Tightening the bolt 61 will push the pressure block 62 to press against the inclined surface of the slide 2, thereby fixing the slide 2 to the base 1.

[0027] The fixing component 5 is composed of two C-shaped parts, one above the other, which are fixed together by bolts. One of the C-shaped parts is fixed to the slide 2. When the welding head is placed into the C-shaped part on the slide 2, the other C-shaped part is placed on the C-shaped part on the slide 2, and then the two C-shaped parts are fixed together by bolts. In this way, the two C-shaped parts lock the welding head onto the slide 2.

[0028] The working method of this application is as follows: the welding head is positioned on the slide 2 by the welding head positioning seat 3 with the triangular positioning mechanism 4, and the welding head is fixed on the slide 2 by the fixing component. Then the slide 2 is inserted into the base 1, and the slide 2 and the base 1 are fixed together by the clamping mechanism 6, thereby completing the installation and connection of the welding head and the automatic welding machine.

[0029] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
