Description

Mechanical upward grinding online tool for center plate seat on vehicle and upward grinding device

Technical Field

The application relates to the technical field of maintenance tools, in particular to an upward grinding online tool and an upward grinding device for a mechanical center plate seat on a vehicle.

Background

The underframe of the body of the railway vehicle is supported on the bogie by means of a core disc or side bearing. The steel structure of the train body bears the dead weight, the load, the preparation weight, the vertical dynamic load generated by the impact of wheel tracks and the vibration on springs, the longitudinal load such as the traction and compression impact force generated between the trains when the train is started, changes the speed and goes up and down the ramp, and the lateral load such as wind power, centrifugal force, the pressure of the goods on the side wall. The upper center plate is installed on a car body sleeper beam, the upper center plate is installed in a riveting mode, the installation plane requirement is extremely high, the tight combination of the center plates is guaranteed, the friction force of the tight combination is enhanced, and the safety of the application of the upper center plate and the safety of the application of a vehicle are guaranteed. However, in the welding process of the central disc seat on the sleeper beam with the steel structure of the car body, the welding stress on the welding process of the sleeper beam steel structure group and the improper processing of the process links can cause the welding stress deformation of the central disc seat on the sleeper beam, the installation flatness is not enough, and the problems of rivet breakage and central disc cracking are caused by load and operation impact in the application process after the central disc is riveted and installed. Therefore, before the upper center plate of the vehicle sleeper beam is installed, the plane of the center plate installation seat must be checked, the contact surface is more than 80%, when the vehicle in use has the problems of rivet breakage and center plate crack, the welding stress deformation of the vehicle body steel structure sleeper beam often exists, the flatness of the upper center plate seat is not enough, and therefore the deformation surface must be polished.

In conclusion, the flatness of the center plate seat on the railway vehicle sleeper beam is related to the stress of the car body steel structure sleeper beam in welding, when the flatness of the upper center plate seat is not enough, a rivet is broken and the center plate is cracked in application, a deformed surface needs to be repaired and polished when the upper center plate is replaced, the installation surface of the sleeper beam center plate faces downwards, and the used electric angle grinder only can be used for upward grinding operation, so that the manual hand-held operation is difficult and extremely dangerous.
