Piston cooling nozzle testing fixture

The invention discloses a piston cooling nozzle testing fixture, and relates to the technical field of automobile part inspection, the piston cooling nozzle testing fixture comprises a W-direction push-pull handle, a W-direction base, a W-direction standard plate and a W-direction slide block, the W-direction of a piston cooling nozzle is divided into two parts of XZ-direction detection of the piston cooling nozzle and XY-direction detection of the piston cooling nozzle, a three-dimensional shape is converted into a two-dimensional shape, and the two-dimensional shape is converted into a three-dimensional shape. After the projections in the two directions are determined, the space shape of the piston cooling nozzle is determined, and by designing the XZ-direction piston cooling nozzle testing fixture and the XY-direction piston cooling nozzle testing fixture, qualified piston cooling nozzles can be more accurately and efficiently selected for assembly, the fault occurrence rate of an engine is reduced, and th
