The specific positional relationship and structure:

The bottom of the mounting plate of the short axis fixture can be connected with the stepping rotation motor. After connection, the rotation of the stepping rotary motor can be controlled according to the laser welding speed and other needs, so as to ensure the welding quality.

The clamp base is fixed above the clamp mounting plate.

The fixture cylinder is divided into two pieces, which are arranged symmetrically on both sides of the bracket, and push the limit pressing piece to compress the workpiece. The transmission rod is connected with the transmission end, and its other end is connected with the cylinder block.

The brackets are rigidly attached and secured above the base of the fixture.

The boss is arranged on the upper part of the bracket.

The limiting pressing piece is divided into two pieces, which are arranged symmetrically on both sides of the boss; the fulcrum of the limiting pressing piece is set on the bracket, which moves around the fulcrum under the push of the clamp cylinder.

The pressing end is arranged on the inner side of the limiting pressing piece, and the pressing ends on both sides can just be pressed together on the top of the boss.

The transmission end is arranged outside the limiting pressing piece.

In a further optimized solution, the fixture base is fixed on the fixture mounting plate by screws and pins.

After adopting above-mentioned technical scheme, the beneficial effect of the present invention is:

Compared with the disclosed fixing technology solution suitable for laser welding of high-voltage vacuum DC contactors, this workpiece fixing device suitable for laser welding has the characteristics of adjusting the pressing force of the welding workpiece, which is conducive to meeting various laser welding requirements. Thereby improving the quality and efficiency of welding.
