Abstract

This application discloses a mechanical characteristic testing system for railway signal relays, comprising a turntable device configured to rotate the railway signal relay base to a first testing station and a second testing station; a contact pressure testing mechanism and an industrial vision camera are adapted at the first testing station to measure the contact pressure of the contact group; a gap testing mechanism is adapted at the second testing station to detect the gap of the contact group, and a contact alignment testing mechanism is adapted to detect the contact alignment; this invention, based on key equipment such as an automated motion mechanism, a line laser profile scanner, a contact pressure sensor, and a railway signal relay base, constructs a testing station for the mechanical characteristic parameters of railway signal relays, making the three testing mechanisms independent and non-interfering with each other, and making the system design more compact under the premise that the mechanisms do not interfere with each other.
