Title:
ABRASIVE WATER JET GRINDING SYSTEM AND METHOD BASED ON MULTI-AXIS DRIVE CONTROL
Document Type and Number:
WIPO Patent Application WO/2023/207007
Kind Code:
A1
Abstract:
An abrasive water jet grinding system and method based on multi-axis drive control. The system comprises a grinding vehicle (1), a vehicle control system mounted on the grinding vehicle (1), a steel rail surface damage and front and rear profile detection system (2), a grinding servo drive system (3), an ultra-high pressure water treatment system (4), a water jet grinding system (5), a multi-channel grinding pressure and flow control system (6), and a waste water recovery and separation system (7). The water jet grinding system (5) comprises a grinding lifting mechanism (51), grinding performance mechanisms (52), and an abrasive supply mechanism (53), wherein the grinding performance mechanisms (52) on the same side are respectively used for realizing the rough-fine grinding of a steel rail, a three-axis full-servo drive mechanism is arranged on each grinding performance unit (57) of each grinding performance mechanism (52), and a plurality of grinding performance units (57) are controlled to be subjected to high-precision posture and position linkage by the grinding servo drive system (3), so as to fit with a profile of the steel rail, realizing profiling high-precision grinding of the steel rail; in addition, the high-precision multi-channel grinding pressure and flow control system (6) is designed in a channel of the grinding performance units (57), so as to control water pressure and flow of a water jet accurately.
