Positioning structure of precise water gap cutting machine

The utility model belongs to the technical field of precise water gap cutting machines, and discloses a positioning structure of a precise water gap cutting machine. The positioning structure of the precise gate cutting machine comprises a lower base plate, the lower surface of the lower base plate is movably connected with a front-back air cylinder, the output end of the front-back air cylinder is fixedly connected to the back face of the lower base plate through a fixing block, the upper surface of the lower base plate is fixedly connected with a positioning table, and the lower surface of the lower base plate is slidably connected with a guide rail through a sliding block. According to the positioning structure of the precise water gap cutting machine, the Y-axis positioning assembly and the X-axis positioning assembly are used in cooperation, a lower base plate is pushed to move through a front air cylinder and a rear air cylinder, a stop screw is further pushed through a fixing plate to enable a pressing
