Abstract

The invention discloses an intelligent visual guidance steel rail welding seam finish-milling machining system and method, and relates to the technical field of steel rail machining. The steel rail welding seam finish-milling machining method comprises the steps that a steel rail to be subjected to finish-milling is conveyed to a finish-milling station; positioning and clamping sections are arranged on a steel rail to be subjected to finish milling and distributed on the front side and the rear side of a butt welding seam, and when the positioning and clamping sections are positioned and clamped, the front-back central plane of a rail head coincides with the central plane formed by the corresponding clamps, so that the side plane of the rail head is pre-clamped while the rail head is centered and positioned; the rail top and the rail bottom are clamped, and the side plane of the rail head is clamped; and a finish-milling machining standard is obtained, and finish-milling machining is conducted on the steel rail. According to the clamping device, the rail head is centered and positioned, the side plane of the rail head is pre-clamped, the rail head and the rail bottom are clamped, then larger clamping force is applied to the side plane of the rail head so that the side plane of the rail head can be converted into the clamping state from the pre-clamping state, and the precision of subsequent finish milling machining is guaranteed.
