Bidirectional positioning mechanism for machining mechanical parts

The bidirectional positioning mechanism comprises a hollow machining table, a pair of strip-shaped grooves are symmetrically formed in the upper end of the machining table, sliding rods are connected into the strip-shaped grooves in a sliding mode, Z-shaped plates are fixedly connected to the upper ends of the sliding rods, and clamping mechanisms used for clamping parts are installed on the Z-shaped plates. A first threaded rod and a second threaded rod are rotationally connected to the opposite inner walls of the machining table correspondingly, and the first threaded rod and the second threaded rod are coaxially and fixedly connected through a coupler. By arranging the Z-shaped plate, the clamping mechanism, the control mechanism and the like, mechanical parts can be positioned and clamped bidirectionally from two side edges, the stability and the reliability of positioning and clamping are ensured, the positions of the parts are prevented from deviating in the machining process, the machined parts are ens
