Metal processing positioning device

The utility model discloses a metal machining positioning device. A sliding channel is formed between a clamp body and a front positioning frame and between a first folded plate and a second folded plate. The pressing block is placed above the clamp body and can slide in the sliding channel, and a rear positioning shaft is arranged in the pressing block; the lead screw penetrates through the frontpositioning shaft to form threaded connection with the front positioning shaft, the outer surface of one end of the lead screw is a smooth surface, and therefore the lead screw with the smooth surface is inserted into the rear positioning shaft and extends to the outer side of the rear positioning shaft. The first folding plate and the second folding plate are respectively arranged on the clamp body, and a certain angle is formed between the first folding plate and the second folding plate, so that a workpiece can be conveniently placed in the sliding channel, then the screw rod is rotated, is in threaded connection
