摘要（英）：

The invention relates to an automatic groove cutting device of a plasma cutting torch, comprising a frame (1), a cutting torch rotating mechanism, a cutting torch oscillation angle mechanism, a synchronous pulley transmission mechanism, a link mechanism and a cutting torch (27), wherein the cutting torch rotating mechanism comprises a cutting torch rotating motor (2), a gear (4), a gear ring (5),a turntable bearing (6), a rotating bracket (7) and a transmission bracket (8); the cutting torch oscillation angle mechanism comprises a cutting torch oscillation angle motor (9), a shaft joint (10), a ball screw kinematic pair (11), a transmission ring (12), a guide rail pair (13) and a stroke switch (14); the synchronous pulley transmission mechanism comprises a first synchronous pulley mechanism, a linear guide rail pair (16), a rolling wheel (15) and a second synchronous pulley mechanism; and the cutting torch (27) is vertically arranged on a third swing rod (25). The automatic groove cutting device of the plasma cutting torch has the advantages of compact structure, light weight, good reliability, low cost and simple programming.
