Abstract

The invention provides an automatic-welding special repairing machine for a train coupler knuckle, belonging to the field of automatic welding and relating to an automatic-welding repairing device for a coupler knuckle. A welding gun is automatically adjusted according to the uneven abrasion condition of the coupler knuckle and a work piece distance is highly-precisely repaired. The automatic-welding special repairing machine is composed of a base, an upright post, a cross beam, a cross-shaped slide frame, a welding gun, a pedestal, a rotating shaft, an L-shaped bent plate, a jackscrew rod, an angle adjusting mechanism, a controller and an arc length sensor, wherein the cross beam is installed on the upright post and the cross-shaped slide frame is installed on the cross beam; the weldinggun is installed on the cross-shaped slide frame through the angle adjusting mechanism to realize up-down, left-right and front-back movements; the rotating shaft is installed on the side surface of the pedestal and the L-shaped bent plate is fixedly arranged on the pedestal; a panel of the L-shaped bent plate is provided with the jackscrew rod and is vertical to the rotating shaft; the signal output end of the controller is connected with the welding gun and the signal input end of a welding gun movement control unit; and the signal output end of the arc length sensor is connected with the signal input end of the controller. The automatic-welding special repairing machine for the train coupler knuckle is used for welding and repairing the train coupler knuckle.

Description

technical field [0001] The invention belongs to the field of automatic welding and relates to an automatic welding and repairing device for a train knuckle. Background technique [0002] In recent years, my country's railway transportation has undergone four major speed increases, and the high-speed rail industry is booming. The government and railway departments attach great importance to how to make trains run more safely and at high speed after the speed increase. There have been more and more problems caused by the speed increase of railway vehicles, and the worn parts on the trains have suffered from excessive wear and tear. The movable parts such as the hook knuckle and the brake beam between the carriages are prone to major accidents such as train decoupling, brake failure, or even derailment due to excessive wear and tear. [0003] The knuckle is one of the key parts for the safe operation of the train. In order to reduce the cost, most of the knuckles are not used ...
