Abstract

The application relates to a clamping assembly, a positioning mechanism and a welding device. The clamping assembly comprises a mounting base, a first rotating shaft and a second rotating shaft, which are rotatably connected to the mounting base around their own axes, a first clamping arm and a second clamping arm, which are respectively installed on the first rotating shaft and the second rotating shaft, a driving gear and a driven gear, which are respectively installed on the first rotating shaft and the second rotating shaft, and the driving gear is engaged with the driven gear, and a swing arm, which is connected with the driving gear and can drive the driving gear to rotate under the action of external force. Thus, when the welding mechanism welds the product, the product is clamped and fixed by the first clamping arm and the second clamping arm, so that the product can be kept fixed and cannot shake, the welding quality is greatly improved, and the product quality is further improved.
