[0036] This utility model discloses a plasma cutting machine for easy positioning. First, according to the size of the workpiece to be processed, the lead screw 102 rotates under the drive of the motor, thereby driving the workpiece clamps 4 on both sides to move towards each other. Then, the two sides of the workpiece are placed on the lower side wall of the C-shaped groove inside the two workpiece clamps 4, clamping the two sides. Then, the first telescopic rod 402 in the C-shaped groove extends, causing the clamping plate 403 to press down and clamp the workpiece. Then, the winding machine 301 in the winding box 3 on both sides works, and the winding machine 301 on both sides pulls the movable seat 202 located on the outer edge of one end of the slide rod 201 on the other side, causing the movable seats 202 at both ends of the slide rod 201 to move towards each other along the slide rod 201, thereby causing the support frame 205 placed on the movable seat 202 to converge. According to the position of the workpiece above it, the support frame 205 converges to the bottom of the workpiece. Then, the second telescopic rod 404 retracts, so that the bottom of the workpiece is placed on the top of the support frame 205 to support the workpiece. Then, the plasma cutting assembly can start working to process the workpiece.
