[0030] In this embodiment: when clamping the steel pipe to be welded, the linear motor 18 is started, so that the linear motor 18 drives the linear screw 16 to rotate, and the linear screw 16 is connected to the linear slide 17 through a transmission connection, so that the linear slide 17 drives the lifting slide 3 to move to the position of the workpiece, and then the lifting motor 15 is started, so that the lifting motor 15 drives the lifting screw 13 to rotate, and the lifting screw 13 is connected to the lifting slide 14 through a transmission connection, so that the lifting slide 14 drives the grabbing cylinder 2 to move to a suitable height, and then the grabbing cylinder 2 is started, so that the grabbing cylinder 2 controls the grabbing claw 1 to grab the workpiece, and then the lifting motor 15 and the linear motor 18 are controlled to rotate in the opposite direction, thereby driving the workpiece to the welding station.

[0031] Example 2: A positioning and clamping tool for a grinding device with automatic loading and unloading, also includes a welding fixture, the welding fixture includes a front end chuck 5 and a rear end chuck 6, the front end chuck 5 and the rear end chuck 6 are both fixed on a sliding mechanism; the sliding mechanism includes a push-pull rod 7 connected to the front end chuck 5 and the rear end chuck 6, the push-pull rod 7 is fixed on a moving seat 8, and moving rollers 9 are installed on the left and right sides of the bottom of the moving seat 8, and the moving rollers 9 are connected to a servo motor 10; the moving rollers 9 are rotatably installed on a moving rail 11, and the moving rail 11 is fixed to the bottom of the linear slide rail 4.
