[0018] 2. This kind of fixing fixture for metal parts is provided with a lifting mechanism. When it is necessary to adjust the position of the fixed metal parts, the telescopic end of the driving cylinder can be controlled to drive the lifting slide to move upward. The lifting slide drives the positioning pressure plates at the bottom ends of the two adjusting slides to move upward synchronously through the two lifting slide bars, thereby releasing the position fixation of the metal parts. By rotating the rotating table, it is convenient to drive the metal parts to adjust the position to a suitable position. Then, the telescopic end of the driving cylinder is controlled to drive the lifting slide to move downward, so that the two positioning pressure plates can be moved downward synchronously to fix the position of the metal parts. The above operation is simple and practical, which improves the practical convenience of the equipment. The supporting slip ring supports the rotating table through the rolling contact between the supporting balls and the top wall of the workbench, thereby improving the stability of the equipment structure.
