Mounting structure for three encoders at crankshaft end of press machine

The utility model relates to the technical field of press machines, in particular to a three-encoder mounting structure at a press machine crankshaft end, which comprises a press machine crankshaft, a crankshaft end cover is fixedly arranged at the end part of the crankshaft, the center of the outer end of the crankshaft end cover is integrally connected with a synchronizing shaft, and the shaft end of the synchronizing shaft is connected with a three-stage synchronous output gear box through a first coupler. The gear box comprises an input shaft and three output shafts, the shaft ends of the output shafts are respectively connected with an encoder, each output shaft and a synchronizing shaft of the crankshaft end cover synchronously rotate, and the gear box is supported and mounted in the side direction of the machine body through a bracket. The three-encoder mounting structure solves the problem of synchronous mounting of multiple encoders on the same crankshaft, and ensures the safety and reliability of th
