The invention discloses an oil pipe pitch measuring device, which comprises a baffle, standard oil pipe tapered thread pitch template bodies and bolts. The standard oil pipe tapered thread pitch template bodies are rectangular, and each standard oil pipe tapered thread pitch template body has a group of parallel V-shaped grooves on the surface of one side thereof. The baffle and the standard oil pipe tapered thread pitch template bodies are arranged side by side. The standard oil pipe tapered thread pitch template bodies and the baffle are provided with holes parallel to the V-shaped grooves,and the bolts pass through the holes of the standard oil pipe tapered thread pitch template bodies and the baffle to fix the standard oil pipe tapered thread pitch template bodies and the baffle together. A handle is arranged on the top standard oil pipe tapered thread pitch template body. The positions of the standard oil pipe tapered thread pitch template bodies can be adjusted to ensure the zero setting accuracy of a pitch gauge. The problem that a calibration certificate cannot guide the actual zero setting of a pitch gauge is solved.
