Positioning equipment for positioning shaft machining

The utility model discloses positioning equipment for processing a positioning shaft, which comprises a processing table plate, two groups of support plates, a positioning component and a processing component, and the two groups of support plates are symmetrically mounted on two sides of the top end of the processing table plate through bolts. The positioning assembly is arranged, the positioning shaft is placed between the positioning plates, the first motor drives the first lead screw to rotate, the first lead screw rotates to drive the first lead screw nuts to get close to each other, and the first lead screw nuts move to drive the positioning plates and the connecting rods to move till the two ends of the positioning shaft penetrate into the positioning plates. A clamping and fixing plate is driven by an electric push rod to move, so that the end part of the positioning shaft penetrating into the positioning plate can be clamped and fixed, the positioning shaft is positioned and fixed, the subsequent stab
