A kind of control system of numerical control non-falling wheel lathe and its application method

Abstract

The invention discloses a numerical-control underfloor wheel lathe control system, which comprises a numerical control system PLC, an NCU unit and a human-machine interface HMI, and is characterized in that: the NCU unit is a central control unit of the numerical control system PLC; the NCU unit is connected with the numerical control system PLC through an Ethernet; the human-machine interface HMI is a login interface, realizes information loading and unloading functions through data communication with the NCU unit, communicates with the numerical control system PLC by means of the NCU unit and controls machining of a locomotive wheelset by means of a lathe and equipment diagnosis of the lathe; and the numerical control system PLC comprises a wheelset measuring module, a cutter compensation adjustment module, an automatic turning repair module and an automatic maintenance module. The invention further discloses an application method of the numerical-control underfloor wheel lathe control system. The numerical-control underfloor wheel lathe control system and the application method thereof have the advantages of reasonable design and high practicability, the turning repair method of the locomotive wheelset is simple and convenient in operation, the problem that the highly-skilled personnel is needed for maintenance is avoided, and a pre-maintenance point and real-time detection are set, thereby realizing regular maintenance of the lathe, and reducing failure rate of the lathe and the time required for maintenance.

Description

technical field [0001] The invention relates to a numerically controlled non-falling wheel lathe, in particular to a control system for a numerically controlled non-falling wheel turning bed and a method for using the same. Background technique [0002] At present, with the increase of train speed and the development of urban rail transit, the wear of locomotive wheel sets is also accelerating, the inspection cycle is shortened, and the running density of locomotives is increasing. Therefore, higher requirements are put forward for the maintenance and safety maintenance of locomotives. After a long period of operation of railway locomotives and subway vehicles, the wheel flange treads in contact with the rails will be worn and deformed. In order to ensure the normal and safe operation of the locomotives, it is necessary to carry out repair processing or turning on the locomotives and subway vehicles. Therefore, it is very important to improve the efficiency and quality of wh...

Problems solved by technology

[0002] At present, with the increase of train speed and the development of urban rail transit, the wear of locomotive wheel sets is also accelerating, the inspection cycle is shortened, and the running density of locomotives is increasing. Therefore, higher requirements are put forward for the maintenance and safety maintenance of locomotives. After a long period of operation of railway locomotives and subway vehicles, the wheel flange treads in contact with the rails will be worn and deformed. In order to ensure the normal and safe operation of the locomotives, it is necessary to carry out repair processing or turning on the locomotives and subway vehicles. Therefore, it is very important to improve the efficiency and quality of wheel-turning repair; CNC non-falling wheel turning machine is mainly used for repair processing or turning repair of locomotive wheel sets, and most of the existing CNC non-falling wheel turning machines use step7 for equipment The diagnosis of the problem requires professionals with certain professional skills to diagnose, which has high technical requirements, and it is difficult to realize the diagnosis and maintenance of equipment
