The invention discloses automatic trimming equipment for a wind
turbine blade girder. The automatic trimming equipment comprises a transverse guide rail, a sliding table, a fixed cutter head, a movable cutter head and a sensing detection
system, wherein the transverse guide rail is located on a to-be-
cut girder; the sliding table is arranged in the length direction of the transverse guide rail, the fixed cutter head and a movable cutter head guide rail are arranged on the sliding table; the fixed cutter head and the movable cutter head can move up and down, the fixed cutter head is arranged onthe left side of the sliding table, and the movable cutter head is arranged on the movable cutter head guide rail and can move left and right relative to the fixed cutter head; and the sensing detection
system is connected with the sliding table, the fixed cutter head and the movable
cuter head and used for detecting the position of the girder, and the sliding table, the fixed cutter head and themovable cutter head are correspondingly controlled to move according to the detected signals, so that the to-be-
cut girder is
cut freely. The automatic trimming equipment can operate automatically, produces no dust and is high in
cutting accuracy; two sides of front and back edges of the girder are cut simultaneously, and the working efficiency is high; the automatic trimming equipment senses andcontrols the
cutting width, cuts the girders with different widths and has a wide applicable range; and quality accidents and safety accidents such as cut wounds of workers are avoided.
