Weighing device for engine piston connecting rod

The invention relates to the technical field of automobile engines, in particular to a weighing device for an engine piston connecting rod, which comprises a controller, a weighing platform with a rectangular structure and a righting device for righting the piston connecting rod, and is characterized in that the righting device and the weighing platform are electrically connected with the controller; the weighing platform comprises a plurality of weighing discs and a plurality of weighing sensors, a photoelectric sensor used for sensing a piston connecting rod is arranged beside each weighingdisc, and limiting assemblies are arranged at the positions, beside all the weighing discs, of the weighing platform. The righting device comprises a plurality V-shaped snapping parts which are horizontally oriented to the weighing disc. According to the device, the piston connecting rod can be limited, so that the piston connecting rod is kept vertical, the measurement error is reduced, the dataaccuracy is improved, the
