Numerical control drilling and milling device for train roof

Abstract

The invention relates to a numerical control milling and drilling device for the roof of a train, which comprises a base, a base positioning mechanism, a base fastening mechanism, an X-axis movement mechanism, a Y-axis movement mechanism, a Z-axis movement mechanism and at least one working end. The base positioning mechanism and the base fastening mechanism are arranged on the base. The X-axis movement mechanism is arranged on and connected with the base. The Y-axis movement mechanism is arranged on and connected with the X-axis movement mechanism. The Z-axis movement mechanism is arranged on and connected with the Y-axis movement mechanism. The working end is arranged on the Z-axis movement mechanism. The numerical control milling and drilling device for the roof of the train can automatically perform face milling, hole drilling and tapping in the stroke range after being primarily positioned and stabilized. Compared with machining by manually climbing the roof and machining of a semi-automatic device of Siemens, the numerical control milling and drilling device at the roof of the train is more accurate to position, higher in machining precision and stable, and the machining quality is ensured, the work efficiency is improved exponentially and the numerical control milling and drilling device for the roof of the train is safe and reliable.

Description

Technical field [0001] The invention relates to a drilling and milling processing device, in particular to a numerical control drilling and milling processing device applied to the top of rail transit train cars such as EMUs, light rails and subways. Background technique [0002] As the train carriage is the living and resting space of passengers during the journey, in order to ensure the comfort of the passengers, all pipe lines for water supply, power supply, air supply and ventilation and cooling facilities must be arranged on the roof and then enter the corresponding position inside the carriage. For this reason, it is necessary to open the holes and grooves for arranging pipelines on the top of the train carriages and trim the planes of the partial components to facilitate installation. [0003] In recent years, my country’s high-speed rail construction has advanced by leaps and bounds. At first, we introduced advanced foreign technology, digested and absorbed, and successfull...

AI Technical Summary

Problems solved by technology

A small number of companies have purchased semi-automatic processing devices from Germany's Siemens, which are expensive and inconvenient to maintain

Although the latter has made some progress compared with the manual processing method, when the processing position changes, the displacement of the drilling and milling head is still adjusted by manually turning the handwheel.

Its positioning accuracy is difficult to control, and the positioning method is cumbersome and complicated, requiring several people to work together

For this reason, it cannot meet the requirements of machining accuracy and efficiency of train carriages, which restricts the production capacity
