Description

Amplitude modulator structure for welding equipment

Technical Field

The utility model relates to an amplitude modulator structure especially relates to an amplitude modulator structure for welding equipment.

Background

Generally, a welding apparatus is provided with a modulator, a transducer (not shown) and a welding head (not shown), which can adjust the kinetic energy generated by the transducer to a proper frequency, even if the welding head can weld a workpiece, and the structure of the modulator in the welding apparatus is shown in fig. 1 and 2, which mainly includes a convex ring 11 on the modulator 1, the convex ring 11 is embedded in a groove 22 of the housing 2, a gap is generated between the groove 22 and the convex ring 11 of the modulator 1, so that the adhesive tape 21 is usually filled in the gap to enhance the tightness between the modulator 1 and the housing 2.

Although the adhesive tape 21 can enhance the tightness between the amplitude modulator 1 and the housing 2, when the amplitude modulator 1 and the welding head are welded to a workpiece, the amplitude modulator 1 is inclined to one side due to the soft material of the adhesive tape 21, so that the amplitude modulator 1 cannot accurately apply kinetic energy to the welding head when the transducer applies kinetic energy to the amplitude modulator 1 and the welding head, and the adhesive tape 21 is elastically fatigued or deformed due to long-term use, thereby increasing the failure rate of the workpiece.

Therefore, how to eliminate the above disadvantages is the difficulty that the designers of the utility model want to solve.

SUMMERY OF THE UTILITY MODEL

In view of the above-mentioned problems of the prior art modulator structures for welding apparatuses, it is therefore an object of the present invention to provide a modulator structure that achieves a robust modulator.
