A device for detecting the transport position of train wheels

Abstract

The invention discloses a train wheel transport position detecting device which is characterized by comprising a coarse adjustment unit and a position detection unit, wherein the coarse adjustment unit comprises a pedestal and a sliding seat that is arranged on the pedestal and slides relative to the pedestal, the pedestal is mounted on a steel structure platform on tail ends of train wheel transport roller-ways, and a side face of the pedestal is provided with a calibrated scale on which positions of slide seats corresponding to train wheels of different specifications are marked; the position detection unit comprises a limiting rod, a limiting seat, an optoelectronic switch and a support rack A used for installation of the optoelectronic switch; the limiting seat and the support rack A are mounted on the sliding seat; the limiting rod is mounted on the limiting seat in a reciprocating manner, a head part of the limiting rod extends toward the tail ends of the train wheel transport roller-ways, and a tail end of the limiting rod is close to the optoelectronic switch and does not trigger the optoelectronic switch. The train wheel transport position detecting device be used for accurate positioning of train wheels of all specifications on a roller-way transport line, requirements for positioning of train wheels of all specifications on the roller-way transport line can be met, and position control signals can be provided for a next working procedure.

Description

technical field [0001] The invention belongs to the technical field of position detection during the transportation of disc-shaped parts, and in particular relates to a transportation position detection device for train wheels. Background technique [0002] In order to improve the surface hardness of train wheels, the rolled wheel blanks need tread quenching treatment. The wheel blanks are transported to the front feeding door of the quenching furnace through the roller table. The manipulator will take the material from the roller table and grab the wheels transported to the designated position. Transport it to the quenching furnace for heat treatment. In order to realize the automatic picking of materials from the roller table by the manipulator, a wheel positioning device is installed at the end of the roller table. The device adopts a trapezoidal groove. Two guide rods with spring preload are installed, and a photoelectric switch is installed in the middle of the guide ro...

AI Technical Summary

Problems solved by technology

[0003] Because the wheel is sometimes not in the center position of the roller table during the roller table transportation process, the wheel squeezes the trapezoidal groove on one side. When the photoelectric switch senses the position signal, the center of the wheel does not coincide with the center line of the roller table. After reaching the grabbing position of the manipulator, the center of the wheel deviates from the clamping center deviation allowed by the manipulator, and the jaws of the manipulator cannot clamp the wheel correctly, resulting in the wheel falling and damaging the jacking machine and the transport roller during the process of clamping and retrieving. In severe cases, when the deviation between the center of the wheel and the center line of the roller table is too large, the wheel tipping phenomenon will occur during the jacking process of the jacking machine; in addition, due to the wide variety of wheel specifications, the wheel diameter range covers φ630~φ1250mm. At present, the device mainly By changing the position of the photoelectric switch to adapt to the change of the wheel size, the accuracy of the adjustment position is not easy to control, and the adjustment process is cumbersome
