Abrasive water jet grinding system and method based on multi-axis driving control

Abstract

The invention discloses an abrasive water jet grinding system and method based on multi-axis driving control. The system comprises a grinding wagon, a whole vehicle control system installed on the grinding wagon, a steel rail surface damage and profile front-back detection system, a grinding servo driving system, an ultrahigh pressure water treatment system, a water jet grinding system, a multi-channel grinding pressure flow control system and a waste water recycling and separating system. The water jet grinding system comprises a grinding lifting mechanism, a grinding executing mechanism and a grinding material supply mechanism. The grinding executing mechanisms on the same side are used for grinding the steel rail in a rough-fine mode. A three-axis full-servo driving mechanism is arranged on each grinding execution unit of the grinding execution mechanism, the grinding execution units are controlled to be in high-precision pose linkage through a grinding servo driving system, the profile of the steel rail is fitted, and profiling high-precision grinding of the steel rail is achieved; and a high-precision multi-channel grinding pressure and flow control system is designed in a grinding execution unit channel, so that accurate control over water pressure and flow of water jet is achieved.

Description

technical field [0001] The invention belongs to the technical field of water jet grinding, and more particularly relates to an abrasive water jet grinding system and method based on multi-axis drive control. Background technique [0002] The rail is the most important part of the rail system, which guides the train to move forward along the rail, and distributes the load applied by the wheels and transmits it to the structure under the rail depending on the rigidity of the rail system structure. The main function of the rail is to form a wheel-rail friction pair with the train wheels, providing the train with a continuous and smooth bearing surface as much as possible, and guiding the wheels to roll along the track. The wear of the rail surface during the operation of subway vehicles is unavoidable, and due to various other complex factors, especially the influence of the unevenness of the wheel-rail contact interface, the complex dynamic interaction between the wheel and ra...
